RFID identification technology vehicle automatic counting system

RFID consists of a reader and an electronic tag. RFID radio frequency identification technology is a wireless, non-contact automatic identification technology. Its communication distance can range from a few centimeters to tens of meters, and is almost not affected by the weather environment. RFID electronic tags can input hundreds of bytes of digital information and have extremely high confidentiality. They are recognized as a standard in contemporary information technology. One of the five cutting-edge technologies. By burning 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, storage yards, warehouses, etc., it can be read through the RFID Antenna (card reader) installed above the road. Reading, completely free from manual intervention, improves the speed and accuracy of vehicle traffic counting. Compared with license plate recognition technology based on video and image processing, RFID-based vehicle recognition has high accuracy, is not easily affected by the environment, and can obtain vehicle information accurately and comprehensively.

1 System Principle

The electronic tag has the basic information of the vehicle written in advance through the card issuance management system, such as vehicle ID, license plate number, vehicle owner, fleet, etc. And install RFID electronic tags on the windshields of vehicles at all entrances and exits. At this time, the vehicles have unique ID Cards. Install recognition systems at all intersections, roads and other places where electronic license plates need to be recognized. The identification system operates around the clock. When a vehicle equipped with an electronic license plate enters the identification area, the identification antenna can capture the relevant information in the electronic tag and send it to the backend in real time to help the backend do further processing. If a vehicle without an electronic tag installed enters the system, the vehicle information will not be displayed. The system can cooperate with video surveillance to record the entry and exit of vehicles in real time.

The system consists of the following parts:

RFID electronic tag

RFID Card reader

RFID electronic license plate recognition system

Image capture system

LED display system

Software management system

Language broadcast

The main features of this application:

The electronic license plate (RFID tag) uses a passive card in the UHF (902~928MHz) frequency band, which can be used repeatedly and for a long time without maintenance. The electronic license plate uses anti-removal technology and is installed on the vehicle's front windshield. It forms a unique correspondence with the vehicle and becomes the vehicle's only electronic identity mark. The vehicle's identity information is strictly linked to the vehicle. Using dual-card microwave coupling technology, the glass-medium electronic license plate and the air-medium driver card installed on the vehicle can work synchronously in the same microwave environment, that is, the supervision of the vehicle can be realized.

2 System functions

By connecting the identification system with the software management system, it can provide real-time information about vehicles to the background 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 earthworks, coal mines, quarries, sand fields, and docks;

The electronic tag has anti-tampering function and will be destroyed as soon as it is removed; it meets the requirements of anti-cheating;

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

The system recognition rate under correct installation is >99%;

Recognition distance>10m;

Recognition time <1S;

Correct identification when vehicle speed is <40km/h;

3Application effects

Through the implementation of the RFID electronic license plate recognition system at intersections and crossings, vehicles entering and exiting coal mines and earth-rock construction sites are effectively managed, and the speed of vehicles entering and exiting intersections has increased significantly. This has fundamentally eliminated the phenomenon of vehicle registration and protected the safety of transportation companies and coal mines. legitimate interests.

The RFID electronic license plate automatic counting system does not require manual invoices, which greatly improves the accuracy of counting, reduces errors in counting people, and prevents human cheating. This system can realize bicycle statistics, group statistics, settlement statistics, project material management, etc.

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