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.
