Based on RFID, it can provide independent and uninterrupted system equipment for the passage of vehicles to realize convenient management of vehicles. It has the characteristics of high reliability, high recognition rate, easy installation and maintenance, etc., without manual intervention, and automatically completes a series of on-site data Collecting, comparing and switching gate control work, etc., save manpower, improve work efficiency, and reduce human intervention.
The current management of vehicles is usually manual management and IC card close management. However, the huge number and the frequency of entry and exit have caused the efficiency of registration to be extremely low, and the accuracy of data is also very limited. The main defects are:
1. For manual management, the labor intensity is high, the efficiency is low, and the error rate is high
2. For the short-distance management method of IC card, the vehicle must stop to pick up the card, which is slow and cumbersome procedures
In response to the above problems, the latest generation of automatic vehicle entry and exit system has been launched. It takes UHF RFID radio frequency identification products as the core to replace traditional management methods. Vehicles do not need to stop when entering and exiting. All registrations are realized by the system remotely and automatically without manual intervention. , Put an end to mistakes and cheating.
The vehicle management system based on RFID technology can provide independent and uninterrupted system equipment for the passage of vehicles, and realize convenient management of vehicles. It has the characteristics of high reliability, high recognition rate, and easy installation and maintenance. It does not require manual intervention and can be completed automatically. A series of field data collection, comparison and switch gate control work, etc., save manpower, improve work efficiency, and reduce human intervention.
System composition: The system is mainly composed of electronic license plates, readers, antennas, etc.:
[Electronic License Plate]refers to electronic tags. This article uses the term electronic license plate to appear.
The legal number of the identified vehicle registered in the management department is recorded in the electronic tag. Through the system software, each tag can be authorized to identify whether the vehicle has the right to pass through the door.
[Smart RFID Reader]Installed at gates and entrances, vehicles passing through traffic intersections that need to be monitored, responsible for driving the antenna to transmit signals or receiving signals returned by the antenna, analyze and process the electronic license plate data contained therein, and transmit these data to the PC at the same time, Multiple communication methods can be used to connect with PC.
[RF antenna]Used to transmit wireless signals to activate the electronic license plate, and at the same time receive the wireless radio frequency signals fed back by the electronic license plate, and transmit these signals to the reader.
system design
The RFID vehicle management system involves card issuance, data collection, record query and other links. This section focuses on the data collection part that is closely related to vehicle traffic.
Card issuance: The data information of the electronic license plate is read through the card issuing device and uploaded to the PC, and the electronic license plate is authorized through the software system. After completing the information input, fix the electronic license plate on the vehicle body or paste it on the window glass.
Data collection: When the vehicle passes, the data collection system automatically collects the data in the electronic license plate for registration and judgment.
The system is in the state of automatic monitoring and collection; when legal vehicles enter and exit, the system passes the judgment and opens the automatic barriers so that the vehicles can pass freely. At the same time, the system will record the time of entry and exit of the vehicle. Only when the tag is damaged, the system will automatically prompt and the staff can change the card. When illegal vehicles enter and exit, the system will automatically alarm and the automatic barrier will not be opened.
Record query: according to time, vehicle information and other multi-directional combination conditions, query vehicle traffic data to meet management needs.
System functions
Anti-counterfeiting: Each RFID tag has a unique UID number in the world, and it is unmodifiable, so RFID technology has unparalleled anti-counterfeiting performance.
In the RFID tag, in addition to the UID number, there is also a part of the DATA area, which can write some data information. The vehicle number plate and license information can be encrypted and written into this area, which also has a high anti-counterfeiting feature.
Through the control of the vehicle barrier system by the reader, a vehicle with a false certificate cannot enter or leave a specific area at all.
Borrowing: Since the vehicle license plate information can be encrypted and written into the label, and the image data in the system database can be called, it can be distinguished whether a certain vehicle has the right to use the vehicle license, so as to prevent the phenomenon of vehicle license borrowing. The license and the car are unified.
Anti-theft: If a vehicle license is accidentally lost, we can not only use the above methods to determine whether a vehicle has the right to use the license from the unity of the license plate number and the license. The vehicle pass can also be invalidated by reporting the loss of the owner. Once a vehicle tries to enter a certain area with the reported vehicle pass, it can be recognized on the spot.
Vehicle statistics: Since vehicles are automatically recognized by the reader when they enter and exit the gate, how many vehicles there are in a certain compound and which vehicles can be counted.
Inspection management: The mobile inspection vehicle is equipped with a long-distance radio frequency identification system. The on-board system has a database of legal vehicle information and blacklist (stolen vehicle card number, loss report, and invalid card number information). It inspects illegal vehicles on the road and identifies the vehicle from a long distance. The card number of the car is called, the information and image of the car are compared with the image of the live camera, and the legality is determined: if there is no card or the card is reported lost or stolen in the blacklist, the system will automatically alarm; if the card is legal but not If the file vehicle image does not match, the inspector can intercept it.
