　　Application of RFID recognition technology in automatic vehicle counting system

　　RFID consists of a reader and an electronic tag (Tag). RFID radio frequency identification technology is a wireless, non-contact automatic identification technology. Its communication distance can be from a few centimeters to tens of meters, and it is almost unaffected by the weather environment. RFID electronic tags can input hundreds of bytes of digital information, with extremely high confidentiality, and are recognized in contemporary information technology. One of the five frontier technologies. By burning the license plate number of the transportation vehicle into the RFID electronic tag, when the transportation vehicle enters various transportation nodes such as intersections, unloading yards, storage yards, warehouses, etc., it can be performed through the RFID antenna (card reader) installed above the road Reading is completely separated from manual intervention, which 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, is not easily affected by the environment, and can accurately and comprehensively obtain vehicle information.

　　1 System principle

　　The electronic tag is written into the basic information of the vehicle in advance through the card issuance management system, such as the vehicle ID, license plate number, vehicle owner, and fleet. And install the RFID electronic tag on the windshield of all vehicles at the entrance and exit. At this time, the vehicle has a unique ID card. Install recognition systems at all intersections, roads and other places where electronic license plates need to be recognized. The recognition system runs around the clock. When a vehicle with an electronic license plate enters the recognition area, the recognition antenna can capture the relevant information in the electronic tag and send it to the background in real time to help the background for further processing. If it is a vehicle that does not have an electronic tag installed into the system, the vehicle information will not be displayed. The system can cooperate with video surveillance to record the in and out operations of vehicles in real time.

　　The system consists of the following parts:

　　RFID electronic label

　　RFID reader

　　RFID electronic license plate recognition system

　　Image capture system

　　LED display system

　　Software management system

　　Language broadcast

　　The main features of the application:

　　The electronic license plate (R F I D label) uses a passive card in the U H F (902～928MHz) frequency band, which can be used repeatedly without maintenance for a long time. The electronic license plate is installed on the front windshield glass of the vehicle with anti-dismantling technology, which forms a unique correspondence with the vehicle and becomes the only electronic identification mark of the vehicle. The vehicle's identity information is strictly fixed on the vehicle. Using dual-card microwave coupling technology, the glass-medium electronic license plate and the air-medium driver's card installed on the vehicle can work simultaneously in the same microwave environment, that is, to realize the supervision of the vehicle.

　　2 system function

　　By connecting the recognition system with the software management system, it can provide real-time vehicle information for the back-end system, count the number of vehicles at the crossing, and generate relevant counting statistics reports.

　　This system has the following technical advantages:

　　Work around the clock to meet the needs of industrial environments such as earthwork, coal mines, stone yards, sand yards, and docks;

　　The electronic tag has the function of anti-dismantling, which can be destroyed as soon as it is dismantled; to meet the anti-cheating situation;

　　The data in the electronic tag is encrypted to prevent data duplication;

　　System recognition rate under correct installation>99%;

　　Recognition distance>10m;

　　Recognition time <1S;

　　Correct recognition when the vehicle speed is less than 40km/h;

　　3 application effect

　　Through the implementation of the RFID electronic license plate recognition system at intersections and crossings, vehicles entering and exiting coal mines and earthwork construction sites are effectively managed, and the speed of vehicles entering and exiting intersections has increased significantly. This fundamentally eliminates the phenomenon of vehicle registration and protects transportation companies and coal mines. Legitimate interest.

　　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. This system can realize bicycle statistics and group statistics, settlement statistics, engineering materials management, etc.

　　The staff can check the standard of whether the vehicle is full in the monitoring room. This system saves time and improves efficiency, which is beneficial to vehicle owners and enterprises.
