With the development of domestic manufacturing and processing industries, the use of various molds is increasing day by day. Due to the large variety of molds, such as high quality, high volume, and so on, the existing artificial paper records and other methods have been unable to timely and effectively mold the assets management.
In the RFID mold management system, there are 5 main functions, which are stamping times statistics, out of storage management, mold status monitoring, maintenance record management, and quantitative inventory.
Stamping times statistics
Install four UHF RFID anti-metal labels on the four sides of the mold, and UHF RFID reader and the UHF RFID antenna on the punch press, the reader does not perform reading work or performs data communication with the punch press by default module.
Punching the punch press every time, send a command to the reader and trigger the reader to read the label on the mold once, the passive RFID tag reader will sent to the database records that the mold is stamped once, in order to come to monitor the use of mold purposes.
Out of storage management
In the mold warehouse entrances and exits to install fixed RFID reader and RFID antenna set up at the entrance to form RFID signal coverage. When workers use the forklift to paste the RFID tag mold transport to the warehouse, after the RFID signal coverage area can be read by the reader, the reader will read the data and transferred to the system.
Mold status monitoring
In the warehouse shelves set up long range RFID antenna on the shelves of the mold to read, read the data transmitted to the background through the network system to help managers keep abreast of the current state of the mold in the warehouse.
Quantitative inventory
Workshop staffs equipped with RFID handheld reader, when the need for inventory, the workers using the handheld device to read all the labels on the mold. The retrieved data is compared with the inventory on the handset software.
The use of handheld RFID reader writer in fixed assets management system can greatly improve the efficiency of enterprises, increase benefits and reduce costs in practical work, which helps enterprises to truly implement the principle of strict and economical management. Its easy-to-learn user interface and powerful system features stand out from the crowd of similar software. The time-consuming and labor-intensive work, now one or two people can be easily completed within a very short period of time.
Asset identification monitoring and management system through the use of RFID reader handheld to locate and track the assets of the enterprise to help achieve the same kind of physical and books, improve the effectiveness of asset inventory and return on investment. The main goal is to achieve a comprehensive visualization of corporate assets and real-time information updates, allowing users to more sophisticated asset management so that it can monitor real-time use of resources and the flow, so as to ensure physical and book match.

As one of the key technologies of IoT applications, RFID technology has been widely used in many fields such as industrial automation, commercial automation, traffic control and management, the application of this technology in domestic file management is still in its infancy. Earlier this year, the State Archives passed the acceptance inspection of the archives intelligent warehouse management system based on RFID technology of the archives bureau of Lishui City, Zhejiang Province. The system was appraised as advanced, reasonable and practical.
RFID-based file management systems are very sensitive to environmental factors, so some nuances can affect tag reading efficiency. In the archives room, shelves of iron is the primary factor interfering with RFID signals, if the label attached directly to the iron file entities will significantly affect the read rate. In this regard, Hopeland software R&D personnel has modified several times and testing on the UHF RFID reader parameters and tag chip, so that they match more effectively in order to effectively solve this problem. Considering the problem of signal collision and interference in multiple RFID reader and multi-tag environments, the devices with different types and parameters were compared and tested.
It is understood that the system mainly to achieve the three functions. First, to achieve the orderly storage of file entities. The second is to shorten the file access time-consuming. The last is the file inventory operation standard.

The combination of RFID solutions and asset tracking applications not only solved the worries of jewelers, but also facilitated their business expansion.
A: solar street lamp controller recovery voltage
We often encounter a customer response, my lamp is normal light a few days before, a few days after the rain, can not work properly, check the normal solar controller indicator, the battery also has 12V voltage, lamp source also bright which directly connected to the battery, what is the problem, replace a controller,then good. Here to understand the solar charging controller has a recovery voltage, the general controller recovery voltage point is 12.5V, only when the battery voltage exceeds the voltage point, the solar street lights can automatically reply
B: LED light drive damage
Common LED lights are through a drive power to achieve the constant current LED lights, but this drive accounts for the total power of the total 10% -20%, such as a theoretical value of 42W LED lights, coupled with the drive Actual power may be around 46-50W. When calculating the battery power and battery capacity, you must add 10% -20% to meet the power consumption caused by the drive. In addition, the addition of a drive lead to a process of failure. So now the solar street light controller usually built a constant current source, which reduces power consumption and reduces the possibility of failure.
C: compensation for line loss
Line loss compensation function is still unable to achieve, but this factor we can not ignore, if the line is too long, the output voltage and input voltage drop increases, this will cause the battery in advance undervoltage protection, so that solar lights can not work properly. All in the installation of solar street lights, in order to reduce the line voltage drop, try not to use too thin cable, cable should not be too long. Minimize the distance between the controller and the battery.
DP is the largest mail service operator in Europe. The company has international mail, lightweight goods express delivery business, last year revenues of 1 billion euros. All DP's international courier services pass through the Frankfurt sorting center. Deutsche Post uses RFID technology to track international mail.
RFID is not new to the postal industry. Like other IPC members, DP installed UHF RFID readersat key facilities to make it easier to monitor the quality of international mail services. In addition, DP installed an passive RFID tag reader at the International Mail Terminal to monitor and improve processes.
DP at Frankfurt's International Hub Lyngsoe Systems RFID Reader with UHF RFID Antenna for Reading small part IDs passing through this sorting system. DP provides two different RFID tags: N044044B1U, built-in Impinj Monza 4E chip; AZ9662, built-in Alien Technology Higgs 3 chip.
Cross-country tracking of envelopes is more difficult than that of large cartons. Envelopes are usually smaller and therefore more difficult to scan on the envelope. According to Pandikow, there is no international standard for the 2D code system at the current location. As a result, postal operators typically use manual methods to receive international mail, sometimes re-affixing labels in the country of destination. DP said that the number of small pieces of growth is very fast, which also makes automatic tracking system becomes more and more important.
UHF RFID can simultaneously read both near-field and far-field RFID labels. Due to the diversity applications, an UHF RFID reader can more efficiently satisfy read requirements in many operating environments. For example, in large parking lots, such as small and medium-sized trucks, trucks, staff and visitor vehicles, etc., their security access control systems must consider the requirements and restrictions of all vehicles. UHF RFID has the advantages of far-field reading, to meet the needs of different high and low reading position, for example, patrol large range applications (such as university campuses or large hospitals), the long range UHF RFID reader mounted on the patrol car, patrol officers sitting in the car and directly read and verify the electronic tag data.
UHF technology to achieve personnel and vehicles access control. Personnel vehicles entering and leaving the control zone, only need to bring a proximity card, indoor and outdoor access card. Not only can we avoid the extra vehicle-specific card production costs, but also integrate vehicle and personnel access control card management at the same time. UHF RFID technology is ideal for access control systems in communities, office buildings, industrial parks, hospitals or campuses.
In addition to vehicle RFID reader, UHF RFID security access systems are often equipped with handheld RFID readers for property management applications such as campus or factory patrols. The near-field and far-field advantages of UHF RFID technology allow the patrol crew not to be close to the vehicle glass and to hold the RFID hand scanner in the front of the vehicle for direct reading and verification of the electronic tag data.
UHF RFID technology has great potential in security access control applications. In addition to supply chain and logistics management applications, UHF RFID readers are in parking lot management to provide advantages over existing low-frequency and high-frequency RFID security access products.
The Internet of Things has been slowly penetrating into our daily life. The exchange of information between things and things and between people and things has been further reflected. One of its core technologies, RFID radio frequency technology, has gradually entered market.
With the development of RFID technology and the decrease of the price of RFID tags and passive RFID tag reader, which automatically identify the target objects and obtain relevant data. This technology has the tendency of replacing the bar code and 2D code.
Most important, the future development. Due to the strong demand of individual users in the future, a single product can not meet the future development and market demand. In the future, RFID technology will be combined with sensors, GPS and biometrics to be developed from single identification to multi-function identification.
Compared to other anti-fake technology, RFID has advantages below:
RFID room automatic guidance system contains remote RFID reader at where it need to place the guide, when the person passing through the card is automatically identified at long-distance (the card can be put anywhere on the player). And system shows the cardholder the location of the room and the electronic map animation guide. The system can also be extended, such as access control, VIP, multimedia player and other functions.
The scope of application: intelligent buildings, modern office buildings, hotels, guesthouses, KTV, fitness center, sauna, bath center etc
Now most of the hotels or KTV are using the waiter to lead the customer to the designated room, so not only waste a lot of labor, but also inefficient, RFID automatic room guidance system has the following advantages:
(1) quick scan recognition
Once the client arrives at the designated coverage area (such as the elevator hall, etc.), the long distance RFID reader system automatically identifies and guides the customer.
(2) Save Labor
Because it is fully automatic guide, so no human operation, great savings in labor costs, improve work efficiency.
(3) Enhance the image quality
Customers enjoy more than just services, more importantly, the feeling, can give customers completely different feeling of the past, more innovative services.
The application of RFID technology in production management helps manufacturers to monitor the operation of production line equipment components and manage the products in and out of warehouses, and manage the warehousing of distribution centers.
Due to the non-visual reading of RFID technology and the multiple labels reading, multiple RFID reader read all of its logistics data at one time and accurately, which greatly enhanced the efficiency of process management in the supply chain of manufacturing enterprises.
Supply process management: System contains procurement control, order matching, supply cycle control, quality tracking, commissioning process control, in-transit cargo tracking.
Production process management: The key part of whole production, with material cost control, production statistics, pieces of statistics. According to user needs, solution with Ethernet RFID reader and labels can also achieve the production line equipment operation monitoring and management.
Logistics Management: Order product distribution, multi-library collaborative operations, storage warehouse, issuing operations, in and out of stock alarm, unsalable product statistics etc.
The system’s aim to achieve the "supply - production - logistics" optimized management, improve the efficiency of production processes, business cost control and management, effectively implementation of product logistics operation monitoring and management.
Through the RFID tag uniqueness, give each car a unique ID, and then create a database, the name of each car, model, time and other information related to the corresponding ID number, stored in the database. Staffs in a car company can view or enter directly the vehicle's detailed information by RFID tag ID number in the company's permission system platform.
System Technical Features:
For each vehicle attached a unique electronic RFID tag, to ensure the normal use of a variety of environments. Then use UHF industrial RFID reader to complete the electronic tag information entry and query, effectively play the role of vehicle management.
The company has 50 stores each equipped with a long distance RFID reader, within the range can be read, you can quickly identify the vehicle's name, model, store time, quantity and other information, greatly reducing the human inventory time, improve the work efficiency and accuracy of the store.
When vehicle store, they use handheld RFID reader writer to read the code, enter each vehicle information. So at the end of the month, workers could be informed of the vehicle's name and model, store time, quantity and other related information with an industrial handheld data collector.
In the traditional manufacturing enterprises' production flow, most of the production modes are dominated by one-piece flow mode. The biggest disadvantage of this production line mode is that backlogging usually takes a large amount of semi-finished products in some bottleneck processes. If the process is complicated more production links, this phenomenon will be more serious.
The RFID production line management system replaces the traditional paper tickets with electronic RFID tag for each work piece on the production line and an RFID reader device at each station. When the worker completes the homework once, the system automatically sends the information of the work piece to the computer system through the RFID reader system. The system automatically calculates the piece-rate wage and various production statistics and provides a complete set of solutions for the enterprise.
Based on RFID technology, production line management system is one of the effective solutions to solve the above problems. Through the use of RFID reader hardware and system, can automatically collect production data and equipment status data, and provide production managers with "real-time data" of all the process steps in the production line. Combined with the process characteristics of the process equipment and related process, quality indicators of the parameters of the production of important aspects of the process parameters and equipment operating parameters and other production information online monitoring and analysis to help enterprises achieve the production process semi-finished products, finished product process measurement , warehousing storage management automation and information integration, which can effectively monitor the production positions, the stability of the product quality and process parameters to monitor the implementation rate.
With the first application of RFID technology in product manufacturing industry, rising labor costs in retail industry, increasing demand for reducing logistics costs, and the need for retail enterprises to compete and develop themselves, the rise of unattended retail / smart retail stores, will provide objective impetus for the rapid application of RFID technology in modern retail industry. It can be predicted that RFID technology will play an increasingly important role in enhancing the competitiveness of modern retail enterprises.

Solar controller, used in solar photovoltaic system, coordination of solar panels, batteries, load work is a very important component of the photovoltaic system. The controller is different from other solar controllers, adding comprehensive protection features that make the entire solar photovoltaic system efficient and safe operation.
In off-grid PV systems, solar charge-discharge controllers that are used to protect battery overcharge and over discharge and extend battery life are essential. After years of development, pulse width modulation (PWM) type charging controller technology has been very mature. However, we found that in actual cases, the amount of electricity generated by a photovoltaic power station after operation is often lower than the original design value of the building, which not only results in system waste but also brings a lot of inconveniences to the application.
How to solve this problem reasonably presents a challenge for everyone. Some may increase the amount of power generated by designing larger solar panels, but this result will inevitably increase the system cost even more. Is there a way to increase power generation without increasing system costs?
MPPT controller is undoubtedly a good choice. The so-called MPPT (Maximum Power Point Tracking) is the maximum power point tracking.
The maximum power point tracking controller is designed in the controller can be a smart computing and tracking devices at any time to achieve real-time monitoring of solar panels generate voltage and tracking the highest voltage and current values(VI), by the output of the highest point Power, so that the system with the highest efficiency of the battery charge.
We know that in order to charge a battery, the output voltage of the solar panel must be higher than the current voltage of the battery. If the voltage of the solar panel is lower than the voltage of the battery, the output current will approach zero. Moreover, the output of solar panels is not fixed, but with the radiation intensity, ambient temperature and other conditions change curve, and can make the solar panel always work in the maximum IV curve, then reflect the different designers Level and ability.
The traditional solar charge controller its working parameters is set, it set the parameters of the way (or to constant voltage, or constant current) for the solar panel power transfer will not be based on changes in the surrounding environment Change; and solar radiation, ambient temperature and humidity of these natural environment is changing all the time; therefore, to a fixed way to convert the energy of the solar panel, on the one hand is likely to cause the battery is always in full dissatisfaction On the other hand, it is not possible to make full use of solar panels when the weather is good, resulting in waste.
JNGE POWER is a professional solar charge controller factory in China,our solar charge controller have many types of intelligent solar charge and discharge controllers,they has strong stability and high service life.
At present, although the rapid development of RFID technology, but compared with the bar code, due to cost, use of the environment, technical standards and other restrictions, in a period of time, can not replace the bar code applications, then what should we pay attention when choosing the RFID equipment?
Reading accuracy. RFID tags are mainly attached to material pallets and cargo containers, but in some industries, such as electronic manufacturing enterprises, there are many components and devices. How to ensure that each label can be read by RFID reader device in the rapid production flow is a letter problem to be solved.
Environmental impact. By the workshop environment, in the complex electromagnetic environment, serious interference in the business, RFID electronic tags correct reading and writing is also a big problem, companies want to implement RFID reader system, you need to test in the workshop, it will affect the production progress.
Implementation costs. From the cost point of view, the current cost of the label is still high, the RFID reader cost various from different level, especially for the manufacturing industry, what materials and procedures for the use of RFID systems is an important issue, not every word can be said that the need for rigorous planning.
Data Security. RFID application, privacy and security issues are very important. RFID standard system is related to the control of the information of articles and the control of RFID industry. RFID technology should be widely applied and popularized. The development of RFID standard system with independent intellectual property rights is particularly important. At present, China has started to formulate relevant standards, I believe in the near future, the above problems will also be gradually solved.

By using RFID technologies such as NFC and UHF, intelligent packaging products can be easily tracked and traced through the entire supply chain to ensure end-to-end (that is, from core raw materials to The end of the product life and the entire process of recycling) complete transparency.
Uniqueness, each RFID tag has a unique global number (label can not be copied, copy), you can achieve product security, traceability. Efficient, long distance RFID reader technology with long range and multiple reading function (distance 20M can read thousands of labels per minute).
This integrated technology can also detect if smart packages have been tampered with before reaching consumers. When delivered to consumers, NFC-enabled smartphones can provide additional information to consumers and interact with them.
This visibility and insight is critical for brands and large manufacturers to ensure that their products are properly transported and handled. Consumers get two benefits: smart packaging verifies the authenticity of the product; it also provides care through NFC technology logos and uses interactions with other parties.
It is important to test your RFID equipment before deploying an RFID system. RFID tags can be manually scanned by handheld terminals, or by using active tags and fixed readers/antennas. Active tags have built-in power, while passive tags do not require built-in power. Passive RFID tags from the received RFID reader to send the electromagnetic energy to obtain energy, activated to send data to the outside.
RFID reader can be handheld, it can be fixed. Handheld RFID readers are used to read tags manually, just as you manually scan hardware assets while you walk through the data center. Fixed RFID readers are used to mark those applications, such as items being scanned using an ID card to access the data center or downloaded on a transfer carousel.
Another important part of RFID installation is software that supports communicating with tags. There are many vendors that provide ready-made applications for this purpose, often as part of an RFID packaging solution. Another option is to connect directly to your own infrastructure, through a middleware application, or using a driver that connects to your existing back-end data store.
When deploying an RFID reader device into a production environment, it is important to consider variables such as temperature, airflow, and humidity to ensure that the environment is suitable for use with RFID devices. It is worth mentioning that another important test index is the reading distance. For any RFID deployment, be sure to always achieve a read rate of nearly 100%. There are many potential hurdles to achieving this, including interference from unrelated existing wireless infrastructures and even from many devices in high-density environments.
FedEx has tested several uses of RFID and has been successfully used in FedEx's daily operations. They believe that with the combination of effective monitoring, RFID application in individual areas can make companies and customers achieve more benefits.
In the United States, for example, when a FedEx delivery carrier returns to a van, he can open the door and start the engine by simply tapping the RFID button on the wristband. FedEx has also started testing RFID technology in Australia, mainly using RFID tags and RFID scanners to automatically check and report the status of customs clearance awaiting shipment. Without the help of RFID tags, staff must check and scan each package to confirm the current status of the package before updating the package information in the system for customers' access at any time. With the effective use of RFID technology, we can set up an RFID tag that proactively reports information on each shipment waiting for customs clearance, so that the shipment can periodically signal the RFID reader system.
At present, RFID technology in the express delivery industry, mainly involves the following aspects: First, the distribution center in the courier, for large quantities of parcels and express mail through RFID technology, to achieve express mail automatically, high-speed sorting. In China's small and medium-sized private delivery companies generally use human hand sorting case, the use of RFID technology, together with the automatic sorting system, can greatly improve the sorting efficiency. Second, in the process of express mail transportation, through the RFID tags attached to the express mail, the real-time tracking of the express mail is realized by using the GPS technology(in Android RFID reader) so that the sender and the receiver can inquire the position of the express mail through the Internet to obtain a better service experience. Thirdly, it manages the reusable assets of express enterprises such as vehicles, trays and so on. It utilizes the RFID readable and writable characteristics, and enters the related information of assets into RFID, then cooperates with related systems to realize the lean management of assets.
The system is mainly composed of supervision monitoring terminal, communication platform and monitoring center. Compared with the use of bar codes to collect monitoring target information, the RFID technology has the advantages of automatic scanning without manual contact, strong anti-pollution ability (anti-dust, anti-smog, moisture resistance) and large amount of information, RFID technology to build. A complete RFID system consists of three parts: a tag is a combination of a coupling element and a chip, each tag has a unique electronic code that is attached to an object to identify a target object; passive RFID reader to read (and sometimes for writing) tag information; RFID Antenna (radio frequency signal) is passed between the tag and the reader.
Monitoring terminal work flow is: UHF RFID reader sends radio wave energy to the tag, drive tag circuit will send the internal data, reader in order to receive interpretation of data, and finally sent to the communication platform through the RS232 serial port ARM (Advanced RISC Microprocessor, Advanced RISC microprocessor) to do the appropriate treatment.
The monitoring center is composed of a PC with a public IP address and long range RFID reader. Monitoring center backstage management software using self-developed RFID scanner software, parameter settings can be set up to establish network connection and data reception, preservation, analysis and processing. Under the control of the program, the GPRS module can get a dynamic IP address after power on, it will take the initiative to send a connection request to the monitoring center server, so that the server to establish Socket connection.
The remote monitoring and control system based on RFID technology has the characteristics of fast scanning, no contact, oil resistance, large amount of information and so on. Therefore, this system uses RFID technology to monitor the target and provides a new application scheme for optimizing the remote monitoring system, The need to monitor goals in many areas at high efficiency and at low cost.
RagTagd, an Australian company, has introduced a solution that helps parents of students in schools track their uniforms. The RagTagd solution is to have a collection box with passive UHF RFID reader on the school's Lost and Found Area, with labels attached to school uniforms. Software on the RagTagd server keeps track of items in the box and sends messages to parents.
Lost items in the global school is a ubiquitous thing. Students dressed in coat to go to school, often forget to get back in the playground exercise. By the end of the school year, unclaimed items are often discarded, causing waste.
To solve this problem, companies consider using UHF RFID technology, with RFID tag readers built-in and tagged clothing, and school employees do not need to do anything but simply putting their clothes in the box. Using the RagTagd system, the company sew off-the-shelf UHF RFID tags into garments and then sell it to parents with a unique ID number.
Parents need to activate the label when buying uniforms. This process eliminates the need to download additional applications, and parents simply send the six-character code printed on the label to complete the pairing. The collection box is a plastic box with a built-in RFID reader device and antenna that allows the data to be transferred directly to the RagTagd's server.

The RFID-based fire-fighting equipment management system binds the corresponding asset information in the background by installing RFID electronic tags on the fire-fighting equipment. Through the collection of RFID electronic tag information at key nodes and processes, the detailed information of the assets can be accurately obtained.
The basic framework of the system is as follows:
1. A passive RFID tag is attached to all fire-fighting equipment within its jurisdiction. There is a memory on the tag, which can record the purchase time, expiration time, installation time, person in charge, number of inspections and other information of the fire-fighting equipment.
2. The system creates an electronic file of fire fighting equipment, which is stored in the centralized server of the management department and provides the expiration alarm function.
3. Each unit inspector and supervisory personnel are equipped with a RFID handheld reader. The terminal can communicate with RFID tags on various fire fighting equipment and can also communicate with the host computer (management computer).
4. Each sampling personnel receives the sampling plan from the management department, and then arrives at the designated unit, which in turn reads the fire fighting equipment of the unit. At this time, an inspection record will be formed in the handheld terminal, if the equipment is found damaged or not normal, the sampling personnel will make corresponding choices on the handset and save it in the sampling records.
Many industries in China have used RFID technology. Examples include industry and logistics, including asset tracking and logistics, waste management, animal identification, retail and manufacturing, and healthcare. All tags store the reading and writing functions in the RFID reader device so that the tagged stored data can be updated or read in time, ultimately improving performance through tracking or quality control. So, what's the application of RFID technology in the access control system?
RFID access control systems have long surpassed traditional doorway and key management functions. The security requirements of the modern work environment, departmental administrative work, daily attendance management, and company catering consumption are all closely related to the access control system. The installation of RFID gate reader at public exits and entrances in some office locations, residential apartments, etc., can effectively prevent unauthorized personnel from entering and maximize the protection of the safety of these sites.
In addition, an RFID open access control system is installed at the entrance of major conferences and at the entrances of important event venues. When participants or other personnel entering or leaving the passage pass, the fixed RFID reader automatically senses RFID tag invitations or identity cards held by personnel. Documents, confirming the identity of the person entering or leaving the room. The legitimate users pass through the system and the identity information of the personnel and the pictures taken at the scene are displayed on the screen at the same time. The guards who are on duty can confirm the situation.
The RFID open access control system not only has all the features of the traditional ordinary access control system, but also has the characteristics of open multi-person rapid passage and simultaneous recording of each inbound person's personal information, as UHF RFID reader has functions support multiple tags reading.
In addition to delivery, UAV also play a role in the management of large warehouse shipments. At present, some technology companies have combined UAV and RFID (Radio Frequency Identification) technologies to improve the intelligence of drones.
In some cases, tagged items can pile up or be mounted on a rack to make them inaccessible. High metal environments also interfere with RF signals. These companies typically use portable RFID scanner or vehicle RFID reader, who read the inventory item's tag ID by walking up and down the aisle or through storage and construction areas.
Atlas RFID uses Omni-ID's readers to mount on the bottom of the drone. Atlas RFID uses Omni-ID P400 tags to transmit data to RFID readers, readers use GPS to determine the location of tags, and reads are forwarded to cloud-based servers over Wi-Fi or cellular networks, Jovix The software platform manages the data and provides the user with location information for the tagged items on the map of the area. In the past, workers used vehicle and RFID handheld readers to capture tag IDs while the vehicle was in motion.
The traditional method of reading and co-existing with the UAV is very meaningful, and no one can read the information that cannot be read by the traditional method. At present, it only takes 25 minutes for drones to complete inventory of the project once.
In the collection of production line information, the manual acquisition and manual input methods have the problems of insufficient accuracy and high error rate. It is also easy to cause the production data in the system to be unable to be updated in real time and the hysteresis is serious, which is not conducive to the smooth progress of the production flow.
Through the adoption of Internet of Things (RFID), wireless sensing technology, and network technology, real-time tracking and data collection of manufacturing assembly line production processes are realized, thereby improving the visibility and controllability of the manufacturing process of the workshop and increasing the production efficiency of the company.

During inspections, the inspector automatically sends a message to the center via the RFID hand scanner (every 2 minutes, interval can be set) to report information such as the position and time of the current inspector. If a fault is found, the type of failure, device number, through handheld RFID reader the information are sent to the monitoring center.
The monitoring terminal uses the RFID system to display the inspection status on the software in real time, such as displaying the fault points found by various inspection personnel, the emergency status of various types of faults, the processing status, the current status, and the position of each inspection personnel at a certain time.
The tower is affixed with an RFID tag. Through the globally unique identifier, the patrolling personnel must personally go to the site to obtain the RFID identification code, thereby restraining the staff from actually checking in place. At the same time, firstly, the latitude and longitude data of each base tower of all the lines that need to be patrolled are input into the server and the handset. During the inspection process, the lineman locates the latitude and longitude of the towers to be inspected through the GPS global positioning system.
When we walked into a clean and tidy library, we first retrieved the books we wanted to find through self-service borrowing equipment, and then completed the loan. The whole process was quick and simple. This also results in a significant reduction in the workload of the library management staff. It is no longer because of which book to look for. The smart security door will prompt any unfinished registration.
The smart library system quickly reads and writes through the library's RFID tags, and is equipped with floor-level labels (bookcase shelf labels, shelf labels) and special electromagnetic shielding labels for accurate book positioning. It also contains an RFID library card, which uses a card with an embedded RFID tag. It can write and read the basic information of the multiple RFID reader in the storage chip of the RFID tag, and is used for readers' circulation and borrowing operations, and readers.

RIFD application technology is very common in our lives. With the rapid development of the Internet of Things, no one retail is taking RFID to a new height. Is gradually improving our life services, RFID is widely used in security, RFID logistics, anti-counterfeiting of goods, RFID asset tracking and other fields. The RFID Internet of Things technology will be even greater to reflect the application of RFID technology. The Internet of Things needs more technology to build an intelligent entity together.
RFID technology can be divided into three modes: first, tag identification, followed by information collection and analysis, and then target monitoring and tracking. RFID supports "non-contact automatic recognition" technology. This has become the key to wide application. A typical RFID application system consists of RIFD tags, readers (antennas), and interactive systems. When the item is in the collection scope of the long range RFID reader, the RFID tag on the article is received by the reader, the reader performs data decoding and data processing, and the data is packaged and sent to the interactive system, thereby realizing the basic function of the rfid system.
RFID technology has become a great helper in the logistics industry. In smart logistics, as long as an object uses an electronic tag, it can quickly read information and achieve high-efficiency work.
The RFID intelligent transportation system consists of communication technology and sensor integration to form a basic infrastructure, combined with control technology and computer technology to improve the real-time, accuracy and efficiency of the transportation system. RFID Internet of Things technology can enter and exit the vehicle, enter the vehicle identification system automatically, and the RFID parking system can correctly identify information when the vehicle speed is high.
The rapid rise of the Internet of Things has prompted various industries to set off a revolutionary transformation. Make life and technology become a community, life is more intelligent and more convenient. RFID allows each item to truly have its own "identity card." The only identifying information is also the highlight of RFID tags. The field of RFID applications has become a major player in the world of things.
The RFID application field is embodied in many aspects. RFID technology has been used in many urban medical industries. RFID Handheld readers are used to view wards to track the location of patients, and they also play an important role in anti-counterfeiting and tracking of drugs. RFID applications play a very important role in drug management, it can prevent the production and sale of fake drugs to the greatest extent.
RFID applications are also an excellent experience in the automotive industry. This is illustrated by the intelligent manufacturing of the production line. The automotive industry is very advanced in the field of smart manufacturing compared to other industries. Most of the implementation is fully automated. UHF RFID readers can implement automated production lines, due to RFID technology non-visible reading and simultaneous reading of multiple tags.
The smart grid of RFID applications is also very prominent. The construction of smart grids is also one of the major construction projects. Smart grids are faced with information security in all areas of power generation, transmission, substations, power distribution, and electricity use. The RFID technology of the smart grid is better than the barcode, has the advantages of waterproof, high temperature resistance, long service life, long distance to read information, and the ability to store large amounts of data.
As the size of the city expands and people's living standards increase, the number of vehicles on the road becomes more and more. This not only increases traffic pressure, but also imposes higher requirements on the management of vehicles. Is there any new technology to solve these problems? Of course, it is the smart electronic license plate.
The smart electronic license plate is based on RFID solution, and RFID technology is a new non-contact automatic identification technology. RFID-based vehicle identification has high accuracy and is not susceptible to environmental Impact, no blind area, accurate and comprehensive access to vehicle status information and road network traffic conditions.
Taking into account the service life and usage scenarios of electronic license plates, passive electronic tags have the characteristics of long life, small size and easy installation, and low cost, and are more suitable for vehicle installation and use. In the choice of communication distance, UHF 860MHz ~ 960MHz passive RFID electronic tag has the advantages of long communication distance, fast transmission speed, and its use as an electronic license plate recognition is a very good choice.
In recent years, the government has clearly put forward the application of high technology such as the RFID parking system and the automatic recognition of license plates. In simple terms, the "wisdom" of smart parking is reflected in: intelligent space search + automatic parking fees. And RFID technology can be used as an effective means of information collection in traffic dispatching systems and can be applied in traffic dispatch management systems. For example, applying RFID to a bus yard management system can realize automatic, accurate, long-distance, and no-stop collection of information when buses with electronic license plates are in and out of a station, enabling the bus dispatching system to accurately grasp the real-time dynamics of bus access to public parking lots.
Clothing products are a fashion product. Many factors such as the season of sales, the location of sales, the taste level of consumers, fashion trends, and the price of the product will affect the sales of products. Therefore, real-time tracking of sales status is a very important management content for apparel industry companies.
Hopeland has created an RFID/barcode data collection and management system for garment industry companies. It uses a mobile solution to carry out real-time data collection from stores and stores via RFID tracking systems to address garment industry in warehouse management. And problems faced in supply chain management.

The long range RFID reader installed at the exit recognizes the comparison between the label on the forklift and the pallet and the shipping data in the background. The sense of the goods to be shipped is automatically lifted and released, and the goods that are not to be sent will notify the administrator to inquire. Can manage drivers and vehicles (requires back-end software support).
The operation of the RFID smart card parking management system is centered on the process of the user's vehicle entering and leaving the parking lot. Based on the RFID technology, the RFID vehicle tag or the electronic license plate is used to integrate the user's individual and the vehicle information he owns into the database. When driving into the parking lot, the long range RFID reader (3-10 meters) automatically senses the vehicle information, so that the owner can quickly enter the parking.
1. Effectively enhance the safety management of vehicles
After adopting the intelligent parking lot management system, the monthly rent card and the stored value card consumers record the corresponding data in the computer, and the card can be reissued in time after the card is lost. In the case of equipped with image contrast equipment, all types of parking cards have a license plate number archive, one card is dedicated, the license plate does not prompt the computer at any time, and warns.
2. Durable and reliable, fully automated operation
The RFID parking management system adopts a passive RFID card, which is maintenance-free, has a long service life, is fully sealed, and is free from contact. Therefore, it is dustproof and waterproof. It does not need to manually open the gate. The system automatically reads the card, checks the card, and opens the gate.
3. Unattended mode
Reduce labor costs, support high-definition cameras, and achieve vehicle image comparison, so that vehicle information can be checked and checked in and out. To achieve multi-card coexistence, the system supports most IC cards and ID cards at home and abroad, which facilitates the classification management and provides good services for car owners and their vehicles.
4. Solid anti-fake performance
The RFID system uses complex encryption algorithms to make RFID identification cards difficult to forge.
With advances in materials technology, RFID tags are becoming smaller and smaller, and can even be washed without damage, making RFID applications more widely available. Hopeland has developed a number of unique RFID tags, UHF RFID readers and software that can help solve problems or increase the efficiency of customer operations. Applications include retail, medical and healthcare, smart factories, laundries and entertainment.
Retail is the primary application area for RFID solutions, RFID tags are small, helping to prevent counterfeit goods by embedding RFID tags in luxury branded products or jewelry to verify the source of the product.
RFID tags are washable, allowing the laundry to be controlled by RFID, quickly controlling the lending and returning of sheets, towels and pajamas in the hotel, which can also withstand washing and drying.
A system that automatically removes luggage from luggage or clothing or records the storage location of clothes by assembling multiple RFID readers in hotel cloakrooms or dry cleaners, and linking tag data to automatic sorting units that sort luggage or clothing.
Hopeland also introduced a smart factory RFID solution for Industry 4.0 that connects things in the plant (products, production equipment, etc.) to the Internet of Things (IoT) to increase industry efficiency and innovate. In terms of device control, product information is automatically read from the long range RFID reader and the operating conditions are automatically set and registered. If the wrong product is set, it stops working to prevent errors.
The management and application of RFID technology in underground pipeline identification and inspection has been put on the agenda by more and more underground pipeline management departments in recent years. And in the gas, water, communications and other fields RFID solution have achieved good applications.
The most basic RFID system consists of three parts:
1. Label: It consists of a coupling component and a chip. The tag contains a built-in antenna for communication with the RF antenna.
2. IoT RFID Reader: A device that reads tag information.
3. Antenna: Send RF signals on the tag and reader.
Underground electronic signs applied to underground pipelines are generally low-frequency, passive, and loosely coupled cards. They are different from the commonly used RF cards in the market. The buried electronic identification requires the following conditions:
1. The structure is hard, resistant to pressure, acid and alkali, and waterproof.
2. The ability to penetrate obstacles, at least have the ability to wear off the cement road.
3. Strong anti-interference ability, at least can distinguish between more than 8 different professional underground pipeline signs.
4. The long warranty period requires that the life of the RFID be as long as the identified underground pipeline.
The clothing industry also has its own special industry characteristics, namely: product style, color, size and other characteristics determine the number of clothing with geometric growth trend, the sales system covers direct, wholesale, franchise and other industries. The apparel industry is limited by its own and industry's shortcomings, and the future development has also encountered bottlenecks. With the development of RFID technology, more companies are now focusing on RFID technology solutions.
(1) Adjusting the flexibility of production: The real-time production management system based on rfid technology monitors and adjusts the production line to achieve JIST management;
(2) Real-time monitoring of product quality: timely feedback and tracking of production information based on RFID technology ensures real-time analysis and processing of production quality, improving production quality and lower unnecessary waste;
(3) Saving production cost: reducing enterprise inventory, production time and labor cost based on RFID technology;
The intelligent terminal design of the system includes four parts: CAN bus interface part, industrial RFID reader, LCD display and keyboard input part, digital input and output part, etc. The detailed description is as follows:
CAN bus interface part: Receive the master control command and send corresponding action signal according to the communication protocol (drive the electric control part to perform corresponding action), and send information to the master according to the received master command or the set program.
Radio frequency identification part: It can directly identify the smart hanger label moving in the pipeline. In addition, the Ethernet RFID reader can not only read the data of the electronic label, but also can repeatedly write data through the terminal.
As a modern school, the management of students and the level of informatization development of the school itself have become an important factor in measuring the overall development level of a school, and it is also the embodiment of the school image.
The 2.4G "safe campus" system for campus access management based on RFID radio technology is developed. The accessibility attendance scheme adopts the data interaction method of remote sensing card reading. By carrying a customized electronic tag (electronic student ID), students will activate the UHF RFID reader deployed inside and outside the school, and send data to the server. The reader will read the message and send it to the server. Judging, the system starts the SMS platform and sends a secure SMS.
Due to the large number of students entering and leaving the school at the peak period and the existence of certain occlusions, the electronic tags are concentrated and the readers have certain read conflicts. However, after the trigger mechanism is added, when the tag is not in the trigger zone, the tag does not transmit 2.4G, which greatly reduces the number of concurrent tags, enhances anti-collision, and improves the ability of the industrial RFID reader.
The simple 2.45G technology realizes accurate label entry and exit judgment, and the channel management has certain difficulties. Combined with the excitation technology, through the two independent excitation zones inside and outside the school gate, the direction of the label can be clearly determined. When the ground exciter triggers the tag, it will send its ID to the tag, and then pass the information to the remote RFID reader through 2.4G.
To make the customers receive the online orders from the Android POS Terminal without the development of their own App, GOODCOM has designed an App that can receive any orders and print the receipt out.
The Android App is a good fit for your business for any online orders, not only for the restaurants online food takeaway, but also for online shopping, etc.
The GOODCOM Android App GcAnyOrder works perfectly, as the user can accept the order and select the expected delivery time(e.g. 15 mins), or reject it.
The Daily Report, Monthly Report, Yearly Report are checkable. Users can design their own printed format on the receipt in an easier way. As the logo can be branded, I do believe it will be an add feature for u.
With the development of the software industry, more and more inventory management software has been developed and applied to the modern industry, which greatly facilitates the production efficiency of modern industry. Then, in seas of management software, what can effectively improve the efficiency of inventory counting? The answer is: RFID technology.
Prior to the use of RFID technology, the store's business was carried out through bar codes, including the arrival and departure of goods and the realization of inventory. The company reported that it was time consuming and expensive and caused a lot of counting errors, which is a typical bar code.
Thanks to the RFID inventory system, the company reported that inventory counts became faster and more accurate, from 12 hours to barcodes requiring cut to only 50 minutes. They can read with RFID during the day and check if there is a different quantity than ideal and require immediate stock replacement. In the portable RFID reader, we can check if there are items that have expired on the gondola.
Another benefit provided by RFID is the improvement in tracking of goods. The transit of goods circulating between regions is controlled by RFID. If the goods are stored in the store, RFID can move the product through the RFID antenna and we can determine if the item is out of stock.
Every new development in radio frequency identification (RFID) systems for industrial environments is designed to increase performance and extend the possibilities of various applications. Different applications need to consider various factors to choose the most suitable RFID system.
Factors to consider when applying RFID:
(1) The distance between the tag and the RFID reader; (2) The speed at which the object can pass in front of them; (3) The data transmission rate.
Data carriers or tags that can withstand high temperatures are an important added value for systems offered to automotive manufacturers. They are also increasingly used in the process of coating curing, in which data carriers can be used because they can pass through the furnace on the vehicle rails. A good system will provide tags with EEPROM and FRAM memory, which can provide almost unlimited number of read and write operations. UHF RFID system can perform fast read and write, typically at a rate of 0.5 milliseconds per byte.
Integrating RFID reader with passive sensors that measure temperature, humidity, pressure and vibration can provide more information for asset monitoring and management. RFID can be applied to most new applications in major industrial sectors. In the past, managing cloud traffic from thousands of tags brought big problems before cloud technology came. Now, with cloud-based applications and services, the burden of IT support can be reduced, and companies can deploy centralized management and centralized implementation without the traditional support and deployment costs.
With the popularization of library management information, how to realize the intelligent and reliable borrowing of books, rapid inventory, search, and organized books, has always been a bottleneck restricting the development of the library management industry. RFID technology is applied to libraries to identify, track and protect library materials through RFID technology and products, to realize the borrowing, shun, search and inventory of books and materials, and to greatly improve the processing of library materials. effectiveness. Thereby, the intelligent level of the book management method is greatly improved, the work efficiency is improved, the labor intensity of the library management personnel is reduced, and the library information management is brought about a revolutionary improvement.
In the 1990s, RFID technology and products began to be widely used in library management around the world. In 1998, the North American Library proposed to use the RFID technology solution as a way for readers to self-service, and then the Rockefeller University Library in New York first installed the RFID system. In 1999, the Farmington Community Library in Michigan became the first public library to use the technology. In 2002, the National Library of Singapore released the first comprehensive library management system for RFID in Asia, which was the first to introduce high-frequency (HF) RFID technology into the library. After using RFID technology, the library borrowing rate has increased by 30 times, the number of staff has decreased by 2,000, and the annual savings of 28 million US dollars have achieved remarkable results in improving management efficiency and improving service levels.
Early foreign libraries mainstreamed high-frequency RFID solutions. Up to 99% of high-frequency RFID technology is used in libraries in Europe and the United States. The National Library of Singapore is one of the early and widely used libraries using high-frequency RFID technology. The library began testing the application of RFID in library circulation, sorting and logistics systems in 1998 and was comprehensive in 2002. Completed and put into operation. Since then, with the increasing maturity and improvement of RFID manufacturers' solutions for library applications, foreign libraries have begun to plan and implement RFID technology and products. The ParkGrove Bookstore in Minnesota, the OglethorpeMall Bookstore in Georgia, and the GailBorden Public Library in Illinois introduce high-frequency smart return books and sorting systems to provide a full range of self-service; Max Planck Europe The Library of Legal History Institute uses a high-frequency RFID tag system with a lifetime of 40 years to manage historical documents; the Australian Regina Regional Library pilots high-frequency RFID at the Wagga City branch and expands it to 10 branches.
The development of RFID in domestic libraries is also very rapid. Since the implementation of RFID technology by the Chengyi College Library of Jimei University in Xiamen in 2006, the number of libraries using this technology has increased year by year. In October 2006, the new library of Shenzhen Library introduced foreign high-frequency RFID technology, becoming the first public library in China to fully use high-frequency RFID tags, opening up a new situation of RFID in Chinese libraries. In September 2008, the National Library Phase II and the National Digital Library were officially opened to receive readers. The new library introduced RFID technology and integrated traditional services with digital services, marking the beginning of universal adoption of RFID technology in China. Since then, in addition to national, provincial and municipal public libraries, some university libraries and some small public libraries have begun to use RFID technology to manage books.
All this shows that the library has reached a consensus on the use of RFID technology to achieve intelligent library management. In order to better serve the majority of book lovers, it is imperative to improve the efficiency of book management through RFID.

On July 12th, it was reported that recently, the Greater Paris Transport Federation, which is responsible for public transportation in the region, voted to replace the Paris traditional paper subway ticket with two types of RFID subway cards.
The report quoted AFP as saying that the two types of subway cards to be launched are called "Free + Pass-Through Card" and "Easy Travel Card", which can be used to take subway, bus, tram (excluding fast track), Paris Regional Express RER (1 and 2 areas only), cableway and bus leading to the two major airports.
The "Free + Passport Card" will be launched in October 2019 and is suitable for people who frequently use public transportation but are not enough to purchase a pass. This type of card is very similar to an ordinary pass card, but it is not a timely deduction in the month, but is based on the actual travel of the passenger within one month and the second month. Therefore, some personal information, especially bank account certificates, is required when handling the card.
The price of Paris subway tickets is currently different. The price that the car temporarily buys from the driver is 2 euros (about 15.63 yuan), the self-purchasing price on the machine is 1.9 euros, and the purchase of 10 stacks of tickets is 1.49 euros per ticket. The "free + pass card" single trip price is 1.49 euros, the Greater Paris Transport Federation hopes to attract users.
The Easy Travel Card will be launched in April 2019 for people who occasionally take public transportation. It can be said that the official replacement of paper tickets is the "easy pass card." This subway card is very similar to the Oyster Cardde Londre in London, England. The subway card is anonymous, and it takes 2 euros to purchase one, which can then be recharged at each subway station.
However, the report said that unlike the London subway ticket, when the passenger is no longer used, the ticket cannot be refunded and the balance in the card cannot be recovered. The Greater Paris Transport Association explained that "but the traffic card has no expiration date, and because it is anonymous, the purchaser can also transfer the ticket to others" and believes that the card can reach 5.8 million users.
The association pointed out that each year, the Paris Region sold a total of 550 million paper tickets, and the introduction of new cards is due to environmental considerations. "We hope to introduce a new subway card to replace the previous paper magnetic ticket, according to the characteristics of different customers, to meet their requirements." The new subway card is not only flexible, saving production costs, but also relatively affordable for consumers. Overall, transportation cards are cheaper to use than buying a single subway ticket.
Meihe factory can make kinds of rfid products for transportation areas,such as the rfid cards ,subway tags ,subway epoxy keyfobs,etc. If you have any inquiry,welcome to email:sales@mhgyjs.com.
Power plants, coal yards, garbage dumps and other units will have a large number of materials transport vehicles entering and leaving every day. It is necessary to carry out procedures such as parking, registration, weighing, etc. The operator manually records the data into the computer, which is time consuming and has a large error rate. It is also easy to breed human fraud and cause a lot of economic losses to the company. The RFID weighing tag is placed on the car, and the relevant data is read by the UHF RFID reader to correspond to the vehicle, which provides great convenience for the staff.
The system includes long range RFID readers, antennas, tag cards, electronic truck scales, main engines, signal lights (red, green), automatic gates, ground sense coils, infrared instruments and supporting management software.
When the green signal light is on, the weighing vehicle enters the lane, and after the vehicle enters the lane, the red signal light is on, prohibiting the next vehicle from entering the lane. The vehicle passes through the induction coil to generate a sensing signal. After the Ethernet RFID reader reads the card, the card information is uploaded to the host database, and the vehicle information is called out.
System advantages
1. The identification accuracy of the car number can reach 99.99%, which is suitable for various harsh environments such as wind, snow, rain and fog.
2. The data in the label is highly confidential, and the electronic label (electronic license plate) cannot be forged or copied, which fundamentally eliminates the phenomenon of copying, forgery and cheating;
3. The vehicle electronic tag uses passive technology, the service life is long, no maintenance;
4. Automatic acquisition speed is fast, can achieve fast weighing, improve the efficiency of weighing, eliminating the phenomenon of queuing too much;
6. Long-distance dynamic identification, the recognition distance is adjustable within 5-25M.
Utilizing the many different characteristics of UHF RFID, people have developed a series of applications in logistics management, electronic payment, anti-counterfeiting, security access control, intelligent transportation, electronic business cards, traditional media development, rapid access, animal and plant management, indoor Fields such as navigation have been widely used.
1. Logistics
The Internet of Things, first of all, rises in the logistics industry. In order to overcome the shortcomings of traditional logistics, the logistics system now uses a combination of radio frequency identification devices, sensors, GPS (Global Positioning System) and the Internet to form a large network for intelligent logistics management.
Because the UHF RFID reader and tag has the characteristics of reading and writing, no direction, no damage, long-distance reading, and simultaneous reading of multiple items, it can greatly improve the record collection speed and accuracy of the information of the inbound and outbound products, and reduce the artificial errors, improve the speed and accuracy of the inventory.
UHF RFID logistics system can realize full-automatic control and management of goods inbound, outbound, mobile, inventory and other operations. It can track and manage the whole process of goods, and can effectively utilize the storage space of warehouses and improve the storage capacity of warehouses. , thereby reducing the inventory cost of enterprises and enhancing the competitiveness of the enterprise market.
2. Intelligent Transportation System
UHF RFID technology is of great significance to promote the development of modern transportation industry and promote the informationization of transportation. It realizes the concept and development trend of management intelligence, logistics visualization and information transparency in the transportation field. Therefore, more and more transportation industries are beginning to introduce intelligent management systems based on UHF RFID to improve their work efficiency and accuracy. As shown in the following figure, the architecture of the electronic toll collection system is shown, which is mainly composed of long range UHF RFID readers, antennas, lanes and UHF RFID tags on the front windshield of the car.
3. Information Retrieval and Integration
Tag identification provides the most critical information extraction function for UHF RFID applications. However, even though the storable information capacity of UHF RFID has been greatly improved compared to other identification technologies, its storage information is comparable to that of From the perspective of the entire Internet, it is still extremely limited. Therefore, based on the limited keyword information of the tag, UHF RFID tags become the window to access the vast digital media world by extracting information on the Internet side, and provide more dimensional perception through this information retrieval and integration. Experience and achieve fast and efficient information management.
The process of information collection is realized by UHF RFID technology. The whole working process of the UHF RFID system is shown in the figure below. The UHF RFID reader continuously transmits the reference signal carrying energy to the surrounding, and the energy is super The high-frequency RFID tag immediately returns the data carried by the UHF RFID reader in a reflective manner by modulating the circuit signal, and the UHF RFID reader decodes the received data and transmits it to the host for processing.
The intelligent bucket management system is based on RFID technology and consists of modules such as antennas, card readers, tags, and application systems.
The principle is as follows: the card reader sends a modulated signal of a certain frequency containing information through the antenna; when the tag enters the working area of the RFID tag reader, the antenna generates an induced current through coupling, thereby providing a corresponding tag for the tag. At this time, the tag determines whether to respond according to the information sent by the UHF RFID reader, whether to send data; when the card reader receives the signal sent by the tag, after demodulation and decoding, the tag is internally The data is identified and sent to the application.
By introducing IoT RFID technology, we have customized the unique tags in the industry. Using specific materials, combined with the bucket injection molding process, the label is almost perfectly implanted into the bucket, giving the bucket a unique and unmistable encrypted ID card that can transport traditional bottled water from production, storage, and logistics. Every link of distribution, distribution, service consumer and empty container recycling is transformed into a set of data flow based on intelligent bucket management system.

RFID radio frequency identification technology uses radio frequency for non-contact two-way communication to exchange data for identification purposes. Compared with the traditional magnetic card, IC card or barcode recognition method, RFID has the characteristics of long-distance and non-contact identification, and has strong adaptability to the environment. Through reasonable design, it can work in various harsh environments and has excellent recognition effect. RFID identification work does not require manual intervention, and is suitable for realizing automatic data collection of the system. At the same time, it can recognize high-speed moving objects and recognize multiple electronic tags at the same time, and the operation is quick and convenient. RFID truck frame management application technology is precisely using RFID technology to manage these points.
The RFID truck frame management system is based on RFID technology. The Sinotrans container truck control system will be based on the successful application of RFID in other fields, combined with the needs of Sinotrans Container Line Management, with automation, advanced, Based on the principle of stability and expandability, the automatic identification and tracking of the container frame is realized around the core business requirements. The core of the system is to install RFID readers and RFID antennas on the front of the container truck, install RFID electronic tags on the frame, and identify the electronic tags through the readers to achieve monitoring and management of the frames. The RFID electronic tag is installed near the front of the frame, and the appropriate mounting position is selected according to the structural characteristics of the frame. At the same time, the frame is made of metal and requires an anti-metal electronic tag. In order to ensure that the electronic tag is not damaged during the use and storage of the frame, the protection of the electronic tag is achieved by making full use of the structure of the frame itself. For a frame that does not have a protective position, the protection of the label is formed by installing a metal baffle or a cushion rubber under the premise of taking into account the reading performance.
At present, the pharmaceutical industry is currently facing the problem of the proliferation of counterfeit and inferior drugs. Some lawless elements are driven by interests to create counterfeit drugs, which threaten people's lives when they take them. With the rapid development of RFID technology, the medical industry in many cities has begun to apply RFID technology. Many hospitals have begun to use RFID handheld reader for ward inspections, and most importantly, RFID technology and handheld terminal products are It has also played a huge role in drug anti-counterfeiting, tracking and supply chain management.
Using RFID technology, when the drug is shipped from the factory, the RFID tag is attached to the drug package, which becomes an inseparable part of the drug. The RFID tag carries all the information. The principle of RFID used for anti-counterfeiting in commodity anti-counterfeiting is to identify the product (The ID), ie the security code (which is encrypted by hardware or software algorithms) is traced and managed through the system management platform, from the supply chain process that the drug subsequently undergoes, and finally to the patient through the retailer or hospital.
Each Ethernet RFID reader can be connected to the server via GPRS or network, and can effectively record and monitor in production, warehousing, logistics and final sales. The RFID tag is the identity card of the drug, and the product identification number (ID), that is, the security code (encrypted by software or hardware algorithm) is written in the RFID chip. This ID is unique in production and storage. In the warehousing and logistics links, including the final sale, although the number of times to collect information is large, the remote RFID reader can be used for non-contact remote identification, so that data can be collected efficiently. Reduce the complexity of manual statistics and queries. Through RFID technology, we can prevent counterfeiting and sales, and improve the handling capacity of accidents. The application of RFID and handheld terminals in drug management supervision still has a large market space.
With the development of information technology, colleges and universities have adopted information technology to strengthen management according to their own needs. In view of the problems in digital campus management, the use of non-contact RFID electronic tag proximity card to achieve "one card" management, and cost-effective.
The UHF RFID readers are installed at the entrance of the school, at the stairs, and at the entrance of the classroom to realize real-time positioning and identification of students. All reader connections form a bus type network connection to the controller. Analyze student attendance by analyzing the raw data collected by students. The attendance of each class will be sent to the teacher's mobile phone in real time for easy check.
As a new technology for fast, real-time and accurate acquisition and processing of information, radio frequency identification (RFID) electronic tags, as an upgrade and supplement to traditional vehicle management methods, meet today's vehicle management requirements. The vehicle electronic tag is installed on the windshield of the vehicle or the campus "one card", and a vehicle RFID reader is installed at the vehicle passage or the parking lot entrance and exit.
The degree of informationization and construction of digital campus is an important indicator to measure the comprehensive ability of school management, scientific research and application, and is an important factor reflecting the core competitiveness of the school. Therefore, digital smart campus has become the trend of campus management development. The application of Internet of Things technology can actively promote the development of intelligent digital campus system, and can effectively solve the difficulties encountered in the construction of traditional campuses, thus providing more efficient and high-quality services for the daily learning and life of teachers and students.
The security industry and RFID technology are inextricably linked. RFID technology plays an important role in the application of products and solutions such as intelligent transportation, smart parking, smart access control, and radio frequency anti-theft.
The barcode technology attaches the barcode information to the article, and scans the barcode on the article through the scanner to obtain the information of the article. The RFID technology attaches the RFID tag to the article, and reads the information in the tag into the RFID reader through the radio frequency signal, thereby obtaining the unique information of the article.
Overall, the main markets for domestic RFID applications are in the areas of identification, traffic management, military and security, asset management, and logistics and warehousing. And in the application of RFID in foreign countries, the absolute main force of retail and transportation logistics. The sum of the two is about 40% of the entire market. Garment applications have been fully deployed in apparel and retail outlets such as Wal-Mart, Metro and Zara.
Specifically, companies need to affix printed RFID tags to each item that needs to be identified, and also need to be equipped with relevant identification devices such as channel machines, handheld terminal, and the like. In addition, enterprises need to integrate RFID with the original ERP system, and the business process will be more complicated than before, and production, transportation and warehousing should be coordinated.
In the short term, “unmanned retail stores” are still hard to become the next explosion point of RFID technology, but it is a new attempt of RFID technology in the field of consumer retail. Of course, RFID technology is just one of the many reasons for the “unmanned retail store” to attract attention. The value of this new retail form is also the collection of big data for offline consumer spending.
The inspection of the equipment is an important measure to ensure the smooth operation of the equipment. The inspection is a time-sensitive work, and the on-duty personnel must periodically inspect each inspection point.
The use of RFID technology and wireless local area network for equipment and pipeline inspection, usually used in power, manufacturing-type enterprise equipment inspection, petrochemical pipeline inspection. Cover the seamless wireless network along the inspection route in the factory area, install an RIFD label at each inspection monitoring point, and record the basic information of the inspection monitoring point.
Each time the inspection personnel first reads the contents of the label with the handheld RFID scanner at a patrol inspection point, the equipment and pipeline are inspected, and the detection information is transmitted to the management office through the wireless network. A patrol management system is established in the background to realize the inspection quality of the inspection personnel through the system, improve the management level of the equipment being inspected, improve the inspection efficiency, and gain insight into the entire inspection work.
The equipment inspection system based on RFID technology mainly includes inspection and dispatch management, inspection line management, inspection information download management, inspection information upload management, inspection information query management, and inspection information report management. The hardware device is mainly composed of an RFID handheld terminal, an RFID electronic tag, and a wireless access point.
The inspection equipment system fully utilizes the physical advantages of RFID technology, mainly utilizing the characteristics of UHF RFID without contact and long reading distance, without manual intervention, thus improving the convenience of inspection personnel and greatly reducing the inspection. The workload of the inspectors. Long reading distance can realize long-distance data collection, and better remote equipment inspection.
Photovoltaic (PV) Panel make electricity from sunlight, and are marvelously simple, effective, and durable. They sit in the sun and, with no moving parts, can run your appliances, charge your batteries, or make energy for the utility grid.
A solar panel array is the energy collector—the solar “generator” and does so via the photovoltaic effect. Discovered in 1839 by French physicist Alexandre-Edmund Becquerel, the photovoltaic effect describes the way in which solar cells create electricity from the energy residing in photons of sunlight. When sunlight hits a solar cell, the cell absorbs some of the photons and the photons’ energy is transferred to an electron in the semiconductor material. With the energy from the photon, the electron can escape its usual position in the semiconductor atom to become part of the current in an electrical circuit.
Most solar cells fall into one of two basic categories: crystalline silicon or thin-film. Crystalline silicon modules can be fashioned from either monocrystalline and polycrystalline.
To use the energy from the array, you may also need other components, such as inverters, charge controllers and batteries, which make up a solar-electric system. The components required are dependent on the system type designed. System types include:
Off-Grid Solar Systems : Although they are most common in remote locations without utility service, off-grid solar-electric systems can work anywhere. These systems operate independently from the grid to provide all of a household’s electricity. These systems require a battery bank to store the solar electricity for use during nighttime or cloudy weather, a charge controller to protect the battery bank from overcharge, an inverter to convert the DC PV array power to AC for use with AC household appliances, and all the required disconnects, monitoring, and associated electrical safety gear.
Grid-Tied Solar Systems : A grid-tied solar system is dependent upon your municipality’s electrical grid. The DC electricity generated by the photovoltaic (PV) panels is sent through a grid-tied inverter, which converts it to AC power that’s compatible with the grid.
With the continuous improvement of people's living standards, it has become an intimate partner of many urban residents' leisure life. Keeping dogs and cats has become a modern lifestyle. In the morning of the flood, some people will walk around with their love dogs. After dinner, some people will take a dog for a walk.
The RFID pet dog vaccine management system fundamentally solves the problem of pet loss, abandonment and supervision. The pet electronic chip with a global unique identification number (UID) will be used as a pet's electronic ID card, and it will be stored in the pet chip for the rest of its life. The basic information of the pet is transmitted to the computer application software through the Ethernet RFID reader, thereby realizing automatic identification and analysis of the pet identity, the owner, and the information of reproduction, health and epidemic prevention throughout the life, and realizing the information of the pet management.
The chip can record basic information about pets, such as name, gender, date of birth, etc. Information such as the type and time of the vaccine received by the pet will be stored in the pet chip or database and will be stored in the pet chip or database. Only authorized personnel can pass the management software or the Internet.
If a pet is lost, as long as it has an RFID pet chip, it can quickly get the information of the pet owner, effectively preventing the increase of stray dogs.
Due to the openness of the pet chip user data area, as long as the RFID reader device conforms to the chip protocol, the pet's open information can be read, so that the pet supervision department, the epidemic prevention department, the pet hospital, etc. can easily share the pet information. The management of pets brings great convenience.
Based on the RFID device and the tableware with the RFID chip, a checkout counter with sensing function is added in the cashier area to complete the intelligent settlement of the meal checkout.

Card recognition is divided into two categories: the first one is a magnetic card, but the magnetic card is low in security, easy to wear and requires frequent magnetization; the second is an RFID card, which is cheap, easy to use, highly secure and can use a database. It is well managed, its cost performance is extremely high, and it has a good promotion prospect.
The working principle of the whole access control system is: one person and one card, and establish corresponding personal information in the database management system according to the serial number of the card. When the door is to be opened, the card is brushed on the lower computer, and the RFID gate reader transmits the serial number to the upper computer server. The server queries the corresponding personal information in the database according to the serial number and transmits it to the lower computer.
At the same time, the lower computer reads the data of the fixed sector block of the card (reading the card), compares the read data with the data sent by the upper computer, and opens the door exactly the same, otherwise the LCD displays an error and does not open the door.
The overall software design of the access control system includes the software design of the lower computer reader and the software design of the database management system of the upper computer. The access control system of the access control system is mainly to realize the reading of the card and the communication with the host computer management system, and is implemented by C language programming in the Keil4 environment.
Through the physical test many times, the RFID access control system designed by this scheme is safe and reliable, and easy to use. And it has a high price/performance ratio compared to other access control systems. With the rapid development of the Internet of Things technology and the promotion of China's gold card project, it is believed that RFID technology will be increasingly applied to all walks of life.

RFID technology can effectively integrate the daily management activities of medical assets with the medical asset management system, so as to achieve the real-time synchronization of physical information and system information, and quickly find various medical assets in an emergency.
Each medical asset is attached with an electronic tag with a unique ID number. When the item with the electronic tag enters the identification area of the reader, the information that the electronic tag keeps issuing will be received by the long distance RFID reader. The writer passes the information to the computer, and the computer system performs corresponding format conversion, filtering, and subsequent statistical processing to determine whether the item should be stored here and other related information.
The outer packaging of the drug is affixed with a barcode, and the drug and barcode information is registered in the background. When the nurse distributes the medicine to the patient, the scanner scans the barcode of the medicine, and then checks the patient's wrist label information, and distributes the medicine to the patient after confirming that the photos, names, and medical names in the hand are consistent. At the same time, the handheld terminal wirelessly transmits the distributed information to the background management center for information storage.
The temperature sensor can be used to continuously monitor the internal temperature for 24 hours to prevent unnecessary loss due to temperature changes. The temperature tag transmits the temperature change signal to the reader, and the reader transmits the signal to the background operating system. When the temperature exceeds the acceptable range, an audible and visual alarm is issued, and the detailed alarm freezer or thermostat location, storage items, etc. are clearly indicated. information.
With the improvement of people's living standards, the number of liquefied petroleum gas cylinders has also increased dramatically. Liquefied petroleum gas has many problems, such as wide use, large quantity, large liquidity, harsh use environment and lagging regulatory measures, which cause huge safety hazards.
Under this background, it is urgent to strengthen the government safety supervision of liquefied petroleum gas cylinders, implement the policy of cylinder construction, fixed-point filling, and regular inspection, and establish a networked dynamic gas cylinder safety management system.

5. Protect and maintain the good integrity brand effect of the product
With advances in materials technology, RFID tags are becoming smaller and smaller, and can even be washed without damage, making RFID applications more widely available. Hopeland has developed a number of unique RFID tags, RFID UHF readers and software that can help solve problems or increase the efficiency of customer operations. Applications include retail, medical and healthcare, smart factories, laundries and entertainment.
Retail is the primary application area for RFID solutions, and Hopeland's RFID tags are small, helping to prevent counterfeit goods by embedding RFID tags in luxury branded products or jewelry to verify the source of the product.
Hopeland also introduced a smart factory RFID solution for Industry 4.0 that connects things in the plant (products, production equipment, etc.) to the Internet of Things (IoT) to increase industry efficiency and innovate. In addition, RFID can also be used in the production process. When a worker holds an IC card with a built-in RFID tag, the work instructions for the worker are automatically displayed on the screen.
In the toy industry, RFID also has a very interesting application, embedding RFID tags in cards or character dolls and then interacting with smartphone apps, arcade games or home video game consoles.
In addition, you can also install the RFID tag on the mini car and install the reader on the race track. When the mini car passes the position of the fixed RFID reader, you can perform various sound and light actions, and you can accurately measure the mini car from The time from the start to the end, and time competition with other netizens through the Internet.
Based on a simple RFID system, combined with existing network technology, database technology, middleware technology, etc., build a "Internet of Things" consisting of a large number of networked readers and numerous mobile tags, which are larger than Internet. ) has become a trend in the development of RFID technology.
The logistics warehousing management system uses RFID technology to capture information, connects it to an open network system through wireless data communication and other technologies, and automatically identifies and tracks the information in each link of the supply chain, thereby building a huge logistics system. A highly intelligent, physical Internet that covers everything between the items on the warehouse and even between objects and people.
The RFID-based Internet of Things will fundamentally change the management level of flow monitoring for all aspects of production, transportation, and warehousing within the scope of global logistics and warehousing. A product with an electronic tag. The electronic tag has a unique code for the product. When the tagged product passes through a passive RFID reader, the information of the product is transmitted to the designated computer via the Internet. This is a Fully automated product flow monitoring network.
Nowadays, the “Internet of Things” is seen as an important driving force for the recovery of the world economy, and its core technology, RFID, has also received much attention. RFID technology has the advantages of non-contact and automatic identification, and has a wide range of applications in logistics management. However, the development of RFID still faces many problems, and technical standards, implementation costs, and information security all constitute major obstacles to the full application of RFID.
Radio Frequency Identification (RFID) is a non-contact, automatic identification technology. The car security anti-theft system uses radio frequency identification technology to automatically identify the target object and obtain relevant data through the radio frequency signal. RFID technology uses RF transmission to read chip data through external materials for non-contact operation.
Communication data uses an encryption algorithm to encrypt data for secure data storage, management, and communication. With the rapid development of electronic technology, the integration of electronic chips has increased, and the cost of RFID systems has been continuously reduced, accelerating the promotion and application of intelligence in the automotive electronics industry.
Taking a four-tire car as an example, the system consists of four tire modules, one RFID reader module and one base station module. The base station module includes an RF receiver, an LF transceiver, a central control part, a human-machine interface, and is used for transmission. Ignition, gated command of the Automotive Area Interconnect Network (LIN) bus.
The four tire modules are installed in the four tires of the car, and the pressure, temperature and battery voltage parameters of each tire are measured in real time, and the measured data is sent to the base station module for processing by RF communication. The base station module receives RF data from the tire module on the one hand, and further determines whether the tire parameters are normal, and performs real-time alarm if an abnormality is found.
The RFID security-based anti-theft system greatly improves the flexibility and security of the system, saves system space, and reduces production costs. It has broad application prospects in the automotive electronics field.
The personal multi-modal biometrics recognition system mainly collects fingerprints, facial images and DNA, and text information into the microprocessor through computer terminals, and then integrates the information into the background and records the individual biometric information database management system through the network. And can be related to other military information about military information, political information, medical care, clothing, wages, housing and other supply relationship information.
At the same time, a unique ID serial number is generated and written into the RFID card by the RFID reader and its biometric auxiliary information. Then, only the RFID reader writer is used to read the ID and the biometric auxiliary information, and after inputting into the computer terminal, the matching query is performed in the individual biometric information database via the wireless communication network or the local area network.
The computer terminal can be applied with a microcomputer based on the Windows.net operating system, and the Linux RFID reader is internally configured, and the extended interface is connected to the biometric collector. In addition to the DNA, other features can be collected and read and written in real time. The information in the RFID card needs to be encrypted while being written. Finally, an individual biometric information database is established.
RFI D radio frequency identification is a non-contact automatic identification technology that automatically identifies target objects and acquires relevant data through radio frequency signals. The identification work requires no human intervention. Compared with traditional barcodes, it has non-contact, rewritable, fast scanning, good penetrability, high security, large data storage capacity, waterproof, anti-magnetic, high temperature resistance, long service life and large reading distance. It can adapt to the complex environmental requirements of modern high-tech local warfare.
From the perspective of technological development, high-frequency technology is relatively mature than UHF technology. Through continuous improvement and improvement, a learning curve model for high-frequency tag production, data protocol sharing, and the basis for constructing RFID applications has also been established.
Both high frequency and ultra high frequency RFID systems rely heavily on the communication environment between the RFID reader and the tag. UHF uses the principle of electromagnetic emission and is therefore more susceptible to electromagnetic interference. At the same time, the metal will reflect the signal, and the water will absorb the signal, all of which will interfere with the normal function of the tag.
The International Organization for Standardization/International Electrotechnical Commission established the ISO/IEC, 15693 standard in 1999 to regulate the implementation of high frequency radio frequency identification technology. The standards for UHF are not so uniform, and the frequencies used in different countries are not the same. The UHF designated by the EU is 865~868MHz, the United States is 902~928MHz, India is 865~867MHz, Australia is 920~926MHz, Japan is 952~954MHz.
The European Telecommunications Standards Institute (ETSI) EN300-220 specification has two main provisions that are less favorable for UHF. One is about the power limitation, which stipulates that the effective radiated power is 500 mW; the second is about the bandwidth limitation, and as a result, the reader cannot be frequency hopped.
RFID tags have received a lot of praise from users in practical applications. Although the price is relatively high, UHF RFID technology has obvious unique advantages in automatic identification and security of products, and the production efficiency and management of enterprises will be has seen an increase.
By putting the license plate number of the transport vehicle into the RFID electronic tag, when the transport vehicle enters various transport nodes such as intersections, unloading yards, yards, warehouses, etc., it can be carried out by an RFID card reader installed above the road. Reading, completely out of manual intervention, improves the speed and accuracy of vehicle traffic counting.
Compared with the license plate recognition technology of video and image processing, RFID-based vehicle recognition has high accuracy and is not easily affected by the environment, and can accurately and comprehensively acquire vehicle information.
The electronic tag is pre-written with the basic information of the vehicle through the card issuing management system, such as the vehicle ID, the license plate number, the owner, the fleet, and the like. The RFID tags are installed on the vehicle windshield of all the entrances and exits, and the vehicle has a unique ID card. The UHF RFID antenna system is installed at all intersections, roads, etc. where it is necessary to identify the electronic license plate.
Electronic license plate (R F I D tag) The passive card in the U H F (902 ~ 928MHz) frequency band can be used for long-term maintenance and repeated use. The electronic license plate is mounted on the front windshield of the vehicle by anti-disassembly technology, which forms a unique correspondence with the vehicle and becomes the only electronic identity mark of the vehicle. The identity information of the vehicle is strictly fixed in the vehicle.
The RFID electronic license plate automatic counting system does not require manual invoices, which greatly improves the accuracy of counting, reduces the error of counting people, and prevents human cheating. The system can realize bicycle statistics and group statistics, settlement statistics, and engineering materials management.
When using the existing RFID Demo software, the length of the read operation cannot exceed 255 words, which is 510 bytes. This is also the upper limit of the amount of data read by Gen2. Reading too much data at a time will also cause the performance of the reading to be unstable. In fact, reading 128 words at a time is not stable. This is related to the performance of the specific label. When actually doing the project, it should be sufficient. After testing, choose an appropriate value as the number of single reads and writes.
There are a lot of UHF RFID tags in the user area, such as 1K bytes, how to read the large-capacity data area? There are two ways to read 1K bytes of data as an example:
Call the readWait SYNC API 4 times, reading 128 words each time;
ReadWait offset=0, size=128 words;
ReadWait offset=128, size=128 words;
ReadWait offset=256, size=128 words;
ReadWait offset=384, size=128 words;
Call the “Actions.TagAccess.Operation Sequence.performSequence” ASYNC API multiple times (recommended this way - good performance)
If 128 words is unstable, you can read 64 words, 32 words or less each time, and the number of calls increases accordingly. The read and write performance of different UHF RFID reader is different. According to the actual test, the amount of read and write data of a single sequence is adjusted; the number of calls is increased accordingly.
As one of the key technologies of security and Internet of Things, RFID is currently rich in related products and solutions, and the market application is gradually deepening. The application fields are expanding and expanding, especially in intelligent transportation, smart parking, smart access control, radio frequency security, personnel and Areas such as item positioning and track management have gradually gained very mature applications.
Taking jewelry management as an example, the jewelry industry has problems in the exclusive counters of specialty stores. The products that the jewelry industry sells every day are high-value jewellery, which is very important for the daily inventory of goods.
However, the current work of jewellery inventory is basically done by manual manual operation, and the jewellery products have the small size and large number of actual situations. A large number of products are counted by a small number of sales personnel, which results in a huge actual situation of inventory work time.
After adopting the RFID scheme, the target object can be automatically identified by the RFID handheld terminal, and the identification work no longer requires manual intervention. RFID jewelry management is to attach RFID tags to precious jewelry products. Combined with the jewelry counting equipment(fixed RFID reader) installed on the counter, it is used to monitor, control and track the labeling of jewelry accessories, enabling fast inventory and real-time management functions.
In addition to convenience, RFID products have high stability, no mechanical wear and long service life, so the maintenance cost is relatively low. This is an important reason for domestic users to accept and innovate the new RFID technology.
Newborn babies are born every day in the hospital, and this new life is the most precious property for every family and parent. According to the statistics report of the medical department, the incidents of baby miscarriage and theft in the maternity hospital have occurred.
RFID baby identification anti-theft system is safe and reliable, not only has comprehensive regional monitoring, including real-time positioning and tracking of tags and regional positioning of events, but also has a fast response rate of alarm events.
Baby and mother wear wristbands, baby wristbands contain active long-range RFID tags, and mother wristbands contain source short-range RFID tags. The baby's active RFID is used by the system to identify its range of activity, and the close-up examination of the infant and mother uses a handheld RFID reader to visually identify the pairing relationship.
A card reader is arranged in the activity space for collecting information about the baby. A fixed RFID reader (adjustable distance, 3-8 m) is installed in each room where the baby is located, and a long-distance card reader (distance is 20 m) is installed in the aisle corridor. Each baby wristband information is automatically uploaded to the application management subsystem for data processing; at important peripheral channels, it is designed to be accessible only to authorized personnel. Maximize the elimination of unrelated people in and out.
In terms of neonatal management, the hospital can not only monitor the position of the baby wearing the anti-theft tag in real time, track and record the movement of the baby, but also implement monitoring and protection more effectively, and can immediately locate the event when an alarm event occurs and stop the theft incident in time.
The bank belongs to the state's key security and prevention units, and has the characteristics of various scales, numerous important facilities, complicated personnel, and a wide range of management areas. As the main circulation place of today's social currency and an important part of the national economic operation, the bank's business involves a large amount of cash, securities and valuables.
In the process of handing over the cash box of the bank's cash-carrying car, there will always be some cases of misappropriation and misappropriation in the process of depositing the cash box, causing economic losses to the bank and causing negative social impacts and potential safety hazards.

Through RFID technology system, it can realize the whole process, real-time and automatic management and monitoring of the entire business process, and respond to the first-time response to the problem, prevent the phenomenon of forgery caused by human factors, and ensure the safety and accuracy of the tail box management and so on.
1: The core function of the solar controller is to charge and discharge the battery in the solar power system. One is to prevent the battery from overcharging, causing the battery to be overfilled and damaged or exploding. The second is to prevent the battery from being over-discharged, so that the battery can not be charged, resulting in failure to be damaged or invalid.
2: Because the environment used is different from the region, the operating temperature of the solar controller is also different. In places with large temperature difference, the solar controller should also have the function of temperature compensation.
3: Other additional functions such as: light control switch, time control switch, etc. These solar controllers should be optional.
A solar charge controller is mainly responsible for regulating the energy which flows between solar modules and batteries used in storing up energy generated from solar panels. And controls the power output of the solar cell module and the battery to the load according to the power demand of the load, which is the core control part of the entire photovoltaic power supply system.
When a PV power system is working optimally, there is the likelihood of the battery getting overcharged. This is because the solar panels are built for the purpose of generating higher levels of voltage which if not controlled could lead to damage of the solar power system.
RFID is a non-contact automatic identification technology. This technology was born during the Second World War and is mainly used to identify aircraft.
The simplest RFID systems include tags, readers and antennas. Additional hardware and software support is required in the real world.
About RFID Reader
The reader is divided into two types: handheld reader and fixed reader. It consists of a transceiver, an antenna, a receiver, and a control module.
Fixed readers generally have multiple antenna ports. Users can have multiple antennas to implement one reader to read and write tags from multiple places at the same time, or configure multiple antennas with different angles for the same tag. To ensure read and write efficiency.
About RFID Tag
The most common is the passive RF system. When the reader encounters the RFID tag, it emits electromagnetic waves and forms an electromagnetic field around it. The tag obtains the microchip circuit in the energy-activated tag from the electromagnetic field. The chip converts the electromagnetic wave and sends it to the reader. The reader puts It is converted into related data. The control calculator can process this data for administrative control.
Modern warehousing and logistics distribution have become more diversified and demanding. Not only must we implement the storage management of goods, but we must also mark the types, quantities, attributes, etc. of goods in the warehouse one by one. Especially in the management of military supplies, high standards and strict requirements are even more needed. RFID technology relies on many characteristics and has been maturely applied in various fields to efficiently improve internal inventory, warehouse positioning, and distribution security control management.
The army material RFID management system is an Internet of Things solution for military weapons, firearms, combat readiness, and other types of material management. Among them, RFID access control system, material management system, alarm system and other systems are combined into one, which not only manages combat preparation materials, but also realizes management of other property materials in the army, personnel authority management, material life cycle management, and maintenance. Reminders and other functions provide favorable guarantees for the management of many materials in the army.
Deploy and install RFID access control systems in the warehouse of combat readiness materials or training materials, and install RFID access doors or RFID reader devices in the warehouses to identify the access to the access channels. First, you need to apply in advance to the reserve materials administrator (the reserve materials administrator only has access to the access control system). All combat materials are equipped with unique electronic ID RFID tags, and the information about the combat materials corresponding to the tags is recorded in the system. At the same time, each person who enters the warehouse to extract strategic materials is equipped with an RFID card with its identity information. After the materials are extracted and passed through the RFID access door, the personnel information and the material information raised by the person will be obtained. Relevant records of personnel information, the system will prompt the successful borrowing of the material. When returning the materials, the system will also record the relevant information of the personnel and materials when passing through the RFID access door to ensure that the materials can be put into the warehouse in time. The material management personnel will use the RFID handheld terminal device. Inventory inspection of the material situation, the inspection situation information is recorded in the system to facilitate the daily maintenance and management of materials.
Intelligent warehouse management with RFID technology can enhance the accuracy and speed of warehouse operations. Reducing the loss of individual assets due to inadequate management in the inflow and outflow of combat readiness materials, laying a foundation for ensuring the security of combat readiness materials. Improve the management and service level of the combat readiness warehouse, and provide favorable guarantees for the work of the army's logistics department, equipment department, and training department. RFID technology combined with network technology to build military asset management to achieve modernization and informationization, and provide intelligent security management for combat readiness and storage.
UHF RFID electronic tags usually refer to electronic tags that conform to the ISO18000-6C & EPC C1G2 protocol. Of course, there are also electronic tags of the ISO18000-6B protocol, but the ISO18000-6B protocol is gradually marginalized.
First, what needs to be considered is the storage structure of UHF electronic tags?
1. What is the model of the chip?
2. What is the memory map of the chip in the chip's specification?
Generally, the electronic label of the 6C protocol is divided into a TID area, an EPC area, a user area, and a reserved area. The TID is the serial number of the solidified chip and cannot be changed. The EPC area is the most frequently used and written area. Some tags have a user area, and some tags, except for the user area, are usually reserved for storing access passwords.
What kind of data do we need to store in UHF RFID electronic tags? Does the data need to be encrypted?
A typical case is the coding method used in the RFID clothing industry.
96 bit EPC, can store 24 HEX in total, how to allocate these 24 HEX is more important, the following figure clearly lists the storage type of a certain garment,
1- 14 for the product UPC
15-19 digits for clothing information such as style, color, size
20--24 digits are the serial number
Access password and inactivation killing password, add according to your own needs, but you need to pay attention to whether the chip itself can perform password operations
Finally, prepare the UHF RFID reader for batch writing.
Indian company Agra Nagar Nigam has decided to simplify solid waste management by installing RFID tags, which are installed in 99,450 houses in 51 communities and handing over 350 RFID handheld readers to cleaners.
Homeowners must put dry garbage and wet garbage in different bins and pay a Rs 65 management fee each month.
When the cleaner collects garbage from the house and scans the RFID tag installed in the house, it will automatically signal to the command and control center of the Agra Smart City Office. After collecting garbage, the homeowner will receive a text message from the mobile phone.
If cleaners do not collect garbage at home, homeowners can also complain through mobile apps.
Homeowners must keep the RFID tags intact. If there is a problem with the label, the homeowner will pay a fine of Rs 100 for this.
The collected garbage will be sent to six collection centers located at different locations in the city. The dry waste is then sent to the processing plant and the wet waste is sent to the composting plant.
Bar codes and RFID tags are both item information identification technologies, and their essence is to give a special number to an item, through which you can get information about the item.
The bar code is numbered by knowing the change of the image by optical means.
The RFID tag can be considered as the electronic version of the barcode, and its working principle is the radio principle. The number information in the RFID tag chip is obtained through the process of electromagnetic wave carrier and modulation.
RFID tag category:
Low-frequency electronic tags:
Its operating frequency range is 30kHz ~ 300kHz.
Typical operating frequencies are: 125KHz, 133KHz (There are other frequencies close to it, such as TI uses 134.2KHz).
High and medium frequency electronic tags:
The working frequency of mid-to-high frequency electronic tags is generally 3MHz ~ 30MHz. Typical operating frequency is 13.56MHz.
UHF and microwave tags:
Ultra-high frequency electronic tag, its typical working frequency is: 433.92MHz, 862 (902) ~ 928MHz;
Microwave range: above 3GHz
Ultra-high frequency (UHF) ranges from 300MHz to 3GHz, and microwave ranges above 3GHz. RFID systems using UHF and microwave are called UHF RFID systems. Typical operating frequencies are 433MHz, 860 ~ 960MHz, 2.45GHz, 5.8GHz, and the frequency wavelength is around 30cm.
UHF tags can be active or passive, and communicate with the reader through electromagnetic coupling. The communication distance is generally greater than 1m, typically 4-6m, and the maximum can exceed 10m.
Radio waves in the UHF band cannot pass through many materials, especially suspended particulate matter such as water, dust, and fog.
UHF readers have very high data transfer rates and can read a large number of electronic tags in a short period of time.
The reader is generally equipped with a directional antenna, and only tags within the directional wave speed range of the reader antenna can be read and written.
The antenna inside the tag is long and label-like. The antenna has two designs, linear and circular polarization, to meet the needs of different applications.
The data storage capacity of UHF tags is generally limited to 2048bit.
From a technical and application perspective, tags are not suitable as a carrier of large amounts of data. Their main function is to identify items and complete the non-contact identification process. Typical data capacity indicators are 1024bit, 128bit, 64bit, etc.
Typical applications include supply chain management, production line automation, air parcel management, container management, railway parcel management, and logistics management systems.
Breast pump suction level is measured in mmHg – milimetres of mercury – which is the standard unit of measuring vacuum pressure. When you’re buying a breast vacuum pump, you might see mmHg in the product listing. This number, generally in the range of 220 to 350, is the maximum suction level. Hospital grade pumps generally have maximum suction levels in the 300 range while personal grade pumps are generally in the 200 range. This doesn’t necessarily make a pump better or worse – it’s just symptomatic of hospital grade pumps having bigger, stronger motors since they are designed for more rigorous use. AJK mini vacuum pumps have been well used in the breast pump products for a long time. The different size and parameters of mini vacuum pumps are used for different suction level of breast pump.
Should you have any more questions about the micro vacuum pump, welcome for inquiry!
RFID Electronic Tags are packaged in many forms, are not limited by standard shapes and sizes, and their composition is also very different, and even requires special design according to various requirements. The Transponder has been used in sizes ranging from ¢6mm to 76x45mm, small or even micron-sized chips, including antennas with a size of 0.4×0.4mm; storage capacity from 64-200bit read-only ID numbers. The small-capacity type is a large-capacity type (for example, EEPROM 32Kbit) that can store tens of thousands of bits of data; the package material is from self-adhesive to open-molded plastic.
The material, composition, and the like of the various package forms of the electronic tag are different.
Card type (PVC, paper, other) laminated, both melted and sealed.
The melt pressure is made by heating the INLAY sheet of the center layer and the upper and lower pieces of PVC material. The PVC material is fused with INLAY and then die-cut into the size specified in ISO7816.
When the chip adopts a Transponder, the chip is raised above the antenna plane (the antenna thickness is 0.01 to 0.03 mm), and another lamination method, that is, sealing, can be used. At this time, the substrate is usually PET or paper, and the thickness of the chip is usually 0.20 to 0.38 mm. When the card is packaged, only the PVC is sealed at the periphery of the antenna, and the chip is not fused, and the chip is not pressed, so that the chip can be prevented from being crushed.
Gluing type, using paper or other materials to make the Transponder upper and lower materials glue together by cold glue, and then die-cut into cards of various sizes.
(1) Label-type paste type, the finished product can be made into the label form of manual or labeling machine, which is the most mainstream product in the application, that is, the electronic label attached to the back of the trademark is directly attached to the object to be marked. Such as aeronautical baggage tags, pallets, etc. Hanging type, which corresponds to clothing and articles using hanging products, is characterized by compact size and can be recycled. (2) Shaped metal surface type, most electronic labels will be affected by metal and will not work properly. These tags are specially treated and can be placed on metal and can be read and written. It is used for the surface of various metal parts such as pressure vessels, boilers and fire-fighting equipment. The wristband type can be used once (eg medical) or reused (eg playground). The animal and plant use type can be an injection type glass tube, a hanging ear tag, a buckle type foot ring, and the like.
With its breakthrough technical features and wide applicability, electronic label technology has been increasingly recognized by the market. With the further improvement of the chip manufacturing process, packaging process, and the maturity of packaging equipment and materials, electronic tags will be more suitable for our needs. At the same time, we have left us with a series of new topics that we need to improve and improve.
Modern warehousing and logistics distribution have become more diversified and demanding. Not only must we implement the storage management of goods, but we must also mark the types, quantities, attributes, etc. of goods in the warehouse one by one. Especially in the management of military supplies, high standards and strict requirements are even more needed. RFID technology relies on many characteristics and has been maturely applied in various fields to efficiently improve internal inventory, warehouse positioning, and distribution security control management.
The army material RFID management system is an Internet of Things solution for military weapons, firearms, combat readiness, and other types of material management. Among them, RFID access control system, material management system, alarm system and other systems are combined into one, which not only manages combat preparation materials, but also realizes management of other property materials in the army, personnel authority management, material life cycle management, and maintenance. Reminders and other functions provide favorable guarantees for the management of many materials in the army.
Deploy and install RFID access control systems in the warehouse of combat readiness materials or training materials, and install RFID access doors or RFID reader devices in the warehouses to identify the access to the access channels. First, you need to apply in advance to the reserve materials administrator (the reserve materials administrator only has access to the access control system). All combat materials are equipped with unique electronic ID RFID tags, and the information about the combat materials corresponding to the tags is recorded in the system. At the same time, each person who enters the warehouse to extract strategic materials is equipped with an RFID card with its identity information. After the materials are extracted and passed through the RFID access door, the personnel information and the material information raised by the person will be obtained. Relevant records of personnel information, the system will prompt the successful borrowing of the material. When returning the materials, the system will also record the relevant information of the personnel and materials when passing through the RFID access door to ensure that the materials can be put into the warehouse in time. The material management personnel will use the RFID handheld terminal device. Inventory inspection of the material situation, the inspection situation information is recorded in the system to facilitate the daily maintenance and management of materials.
Intelligent warehouse management with RFID technology can enhance the accuracy and speed of warehouse operations. Reducing the loss of individual assets due to inadequate management in the inflow and outflow of combat readiness materials, laying a foundation for ensuring the security of combat readiness materials. Improve the management and service level of the combat readiness warehouse, and provide favorable guarantees for the work of the army's logistics department, equipment department, and training department. RFID technology combined with network technology to build military asset management to achieve modernization and informationization, and provide intelligent security management for combat readiness and storage.
UHF RFID electronic tags usually refer to electronic tags that conform to the ISO18000-6C & EPC C1G2 protocol. Of course, there are also electronic tags of the ISO18000-6B protocol, but the ISO18000-6B protocol is gradually marginalized.
First, what needs to be considered is the storage structure of UHF electronic tags?
1. What is the model of the chip?
2. What is the memory map of the chip in the chip's specification?
Generally, the electronic label of the 6C protocol is divided into a TID area, an EPC area, a user area, and a reserved area. The TID is the serial number of the solidified chip and cannot be changed. The EPC area is the most frequently used and written area. Some tags have a user area, and some tags, except for the user area, are usually reserved for storing access passwords.
What kind of data do we need to store in UHF RFID electronic tags? Does the data need to be encrypted?
A typical case is the coding method used in the RFID clothing industry.
96 bit EPC, can store 24 HEX in total, how to allocate these 24 HEX is more important, the following figure clearly lists the storage type of a certain garment,
1- 14 for the product UPC
15-19 digits for clothing information such as style, color, size
20--24 digits are the serial number
Access password and inactivation killing password, add according to your own needs, but you need to pay attention to whether the chip itself can perform password operations

RFID is a non-contact automatic identification technology. This technology was born during the Second World War and is mainly used to identify aircraft.
The simplest RFID systems include tags, readers and antennas. Additional hardware and software support is required in the real world.
About RFID Reader
The reader is divided into two types: handheld reader and fixed reader. It consists of a transceiver, an antenna, a receiver, and a control module.
Fixed readers generally have multiple antenna ports. Users can have multiple antennas to implement one reader to read and write tags from multiple places at the same time, or configure multiple antennas with different angles for the same tag. To ensure read and write efficiency.
About RFID Tag
The most common is the passive RF system. When the reader encounters the RFID tag, it emits electromagnetic waves and forms an electromagnetic field around it. The tag obtains the microchip circuit in the energy-activated tag from the electromagnetic field. The chip converts the electromagnetic wave and sends it to the reader. The reader puts It is converted into related data. The control calculator can process this data for administrative control.

The main function of MPPT controller is to detect the DC voltage and output current of the main circuit, calculate the output power of the solar array, and track the maximum power point. The disturbance resistor R is connected in series with the MOSFET. Under the condition that the output voltage is basically stable, the average current through the resistor is changed by changing the duty ratio of the MOSFET, thus causing current disturbance. At the same time, the output current and voltage of the photovoltaic cell will also change accordingly. The change of the output power and voltage of the photovoltaic cell before and after the disturbance is measured to determine the disturbance direction of the next cycle. When the disturbance direction is correct, the output power of the solar photovoltaic panel will increase, and the next cycle will continue to disturb in the same direction. Otherwise, it will disturb in the opposite direction. In this way, the disturbance and observation will be repeated to make the solar photovoltaic panel output reach the maximum power point.
With the progress of society and the improvement of productivity, the demand for energy is increasing with the development of human beings. The demand for electric power is expected to increase every year. At present, China's power source mainly relies on fire and thermal power generation. Clean solar power generation has gradually prevailed in recent years. The products related to solar power generation system are also numerous and varied in quality. Take inverter and controller products as an example. Many friends who have just entered the industry do not know much about it, which leads to ambiguity in product selection.
For example, a customer asked whether it is necessary to purchase a controller when purchasing off-grid inverter. AnHui JNGE INVERTER manufacturer is popular here:
Firstly, the inverter function is simple and clear, that is, to convert 12V/24V/48V/72V direct current (storage battery, storage battery, direct current power supply) into 110V/ 220V/380V alternating current commonly used in household and the controller is used when charging the battery with photovoltaic modules, which can maintain a stable charging process, avoid the battery from being damaged by overshoot and reverse current damage to the photovoltaic modules caused by reverse current flowing out of the battery. Therefore, the full name of the controller is also called solar charging and discharging controller, which is divided into MPPT type solar control and PWM type solar controller. Everyone should pay attention to the specific use requirements and the configuration of photovoltaic modules when selecting, and select the appropriate inverter or controller.
One, Complete models. Brand models of solar high-power inverters are very complete, especially some big brands will introduce new products every year, in order to enable their brands to occupy the market advantage, and the practicability of high-quality equipment will certainly be stronger. Moreover, the models of major brands are very complete. We need inverters of any style, which can be purchased directly without worrying about shortage.
Second, the quality is guaranteed. To be able to set up a big brand, naturally, has also passed the corresponding national audit, and many businesses are also strictly controlled, only in this way can our brand go further and have greater influence. The quality of branded solar high-power inverters is strictly controlled. Only products with excellent quality can be sold to the market. As long as we can purchase them through formal channels, they can be guaranteed.
Third, the price is more reasonable. In fact, the price of branded solar high-power inverters should be more reasonable, after all, the production methods and costs of such products are close to each other, and the market prices cannot be too different. Compared with other types of products in the market, the brand inverter is more cost-effective. The brand will provide us with high-quality after-sales service and cooperate with such brand merchants. Of course, there is no need for us to worry about any problems.

Why was intelligent access control born?
The fierce competition in business has made business information security the focus of attention, The pursuit of security has led to higher and higher requirements for the security system of modern buildings. The intelligent access control system manages important passages in buildings. The access control system can control the entry and exit of personnel, Ensure the free entry and exit of authorized personnel and restrict entry of unauthorized personnel, Intelligent access control management not only facilitates internal management, but also enhances internal security, thereby providing users with a safe working environment.The access control system based on RFID technology, as an advanced management technology, has been widely used in scientific research, industry, museums, hotels, shopping malls, medical surveillance, banks, prisons, etc. in some countries.
Access Control System (ACS) refers to a system that manages and controls entrances and exits. It not only includes narrowly defined doors for people to enter and exit, but also includes vehicle access control, logistics access control, etc.The management technology of the access control system has already surpassed the simple doorway and key management, but has gradually developed into a complete set of access management technology.
Form a complete access control system
The basic components of the access control system are Identity recognition, sensing and alarm, processing and control, electric lock and execution, wiring and communication, management and setting and so on. All parties coordinate and cooperate to realize the access control system's access management restriction, real-time monitoring, abnormal alarm and other functions to ensure safety and reliability.
The entry and exit certificate is the "ID card" for entering and exiting the system. Only when the system recognizes the entry and exit certificate will it be allowed to pass through the door. Depending on the system, cards, passwords, and biological characteristics of the human body may all be used as vouchers for the access control system.
The recognizer is mainly responsible for reading access credentials and passing data information to the controller. The controller is the core of the entire access control system, responsible for the transmission, processing, control and storage of the entire system data information, and is equivalent to the computer's CPU. The recognizer generally uses the RS232 or RS485 interface to communicate with the controller. Locks are the executive parts of the entire system, mainly electronic locks, magnetic locks and electric bolt locks, etc. The background management software is the operating basis for all hardware coordination and is responsible for the background monitoring and management of the access control system. Managers can use the access control system to set and identify the authority of personnel at any time, directly control the illegal entry of personnel, and record the personnel and time of each controlled area in real time. When problems occur, they can consult historical records and analyze personnel entering and exiting.
Classification of RFID Smart Access Control
The main access control systems on the market can be divided into two categories according to the control method, independent access control system and networked access control system.
(1) Independent access control adopts non-networked control mode,no host computer is needed, but offline control is performed directly through the embedded microcontroller, the independent access control system has no statistics, query and other functions. The social demand for independent access control systems is relatively large. Free-standing access control system price
It is cheap, easy to install and maintain, and is suitable for places with a small number of people.
(2)The networked access control system requires an upper computer to interact with the computer in the control center. The management software required by the access control system is installed on the host computer. Through the software to control the access authority of the electronic tag, implement operations such as issuing and canceling the card, and can query the access control records. Due to more functions, the cost of a networked system is higher than that of an independent system. Such an access control system is often used in situations where there are many users and detailed records of personnel entering and exiting, such as the entry and exit management of the community and the company's attendance management.

A professional RFID hardware system provider, welcome your inquiry!
In recent years, the UDI (Unique Device Identification) system has been used internationally to give identification to medical devices, enabling them to have a unique "identity card" in the product supply chain to help simplify the tracking and recall of medical supplies. RFID electronic tags can track and record the entire life cycle of medical equipment produced. The RFID passive electronic tag chip has an anti-collision mechanism and can be applied to the application of multi-tag identification; due to the special tag design, the tag can be identified and read in all directions, with fast reading speed and high accuracy.
RFID smart healthcare uses the Internet of Things technology to realize the interaction between patients and medical staff, medical institutions, and medical equipment. RFID automatic identification technology can quickly read in batches, store a large amount of information, has the advantages of high security, unique identity, and non-copyability. It can identify medical supplies and efficiently track the production, transportation, storage, and clinical use of medical supplies. The information status can be traced throughout the entire process, avoiding public medical safety issues, and playing an important role in the construction of smart medical care.
The high-frequency inverter power supply converts the original low-voltage direct current into low-voltage high-frequency alternating current through DC/DC high-frequency conversion technology, then boosts the voltage through a transformer, and then rectifies the high-frequency rectified and filtered current into high-voltage direct current with an average value of more than 300V v. Because the high-frequency magnetic core material of the high-frequency sine wave inverter is small in volume and light in weight, the power density of the circuit can be greatly improved, the no-load loss of the sine wave inverter is reduced to be very low, and meanwhile, the conversion efficiency of the sine wave inverter is improved. The peak conversion efficiency of small and medium-sized high-frequency sine wave inverters can reach more than 90%
Power frequency sine wave inverter：
Sine Wave Inverter, Solar Inverter, MPPT Controller, Inverter Power Frequency Inverter Power Supply is used by converting DC direct current into low-frequency AC alternating current and boosting it to 220V mains supply through a transformer. The structure of power frequency sine wave inverter is relatively simple, and various protection functions can be realized in low voltage working environment. In the circuit using the power frequency sine wave inverter, the power supply is stable in operation, strong in anti-interference performance and good in overload capacity, so it is relatively reliable and can suppress higher harmonic components. However, its size is relatively large, its price is relatively high, and its relative power is also very low. According to the current manufacturing process, the rated load efficiency of the sine wave inverter is not more than 90%, so under the condition of no load, its loss is large and its efficiency is low.
The above is a summary of the differences between high frequency and power frequency sine wave inverters. It can be seen that at present, high frequency sine wave inverters has more market value.
Compared with paper barcodes, the RFID operating environment is inseparable from the three major parts of readers, antennas, and RFID tags. Combining the actual situation of clothing retail stores and the characteristics of RFID technology, four main links are used in store warehousing: fast receiving, fast finding, inventory counting, and inventory overview.
When receiving goods quickly, staff use the RFID scanner to scan the delivery note number, enter the detailed list of delivery notes, after scanning, click "Confirm Receipt" to complete the receipt.
When quickly looking for goods, the staff used the scanner camera to scan the barcode of a piece of clothing, and select the color and size. They can also find other colors and sizes of the clothing item.
The number of clothing shelves and warehouses is displayed on the interface. The staff uses the handheld scanner to inspect the clothing. When the pat reader approaches the garment, there will be a voice prompt, and the staff can find the designated clothing in the area.
During inventory counting, the staff creates a new inventory receipt and enters the inventory details page, and use the camera reader to take inventory of the store. After the inventory is completed, the inventory details page will display the corresponding inventory profit and loss status, click "confirm upload" to complete the inventory. The "Inventory at a Glance" page displays the number of all apparel displays and the number of stores in the store in real time for staff to view.
Store sales management module
It is mainly used in four aspects of store sales management: intelligent display, intelligent fitting, reporting, and intelligent cashier. The display monitoring interface displays the clothing status of the current monitoring display area in real time. When the clothing is removed, put back or placed incorrectly, there will be corresponding prompts, And record the corresponding error display record, pick and place record and replenishment information into the system.
When the stock is out of stock for a certain period of time and there is no timely replenishment, the system will automatically generate a replenishment reminder, and the staff will replenish the goods in time according to the replenishment reminder to ensure the display quantity. The sales statistics report is used to count all the garments in transit/inventory, display quantity, sales quantity, fitting times and other data.
When purchasing, the customer places several pieces of clothing in the scanning area of the cashier at the same time. The system quickly scans the clothing information and total price in batches.
