Background introduction
Radio frequency identification card has become the main direction of the development of global automatic identification technology in the 21st century. UHF RFID radio frequency identification is a non-contact automatic identification technology, which automatically recognizes the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient. With the rapid development of smart technology and the general promotion of computer applications, the introduction of smart card application systems in the information management of state agencies, schools, enterprises and institutions is gradually becoming a trend.Shanghai SanierThe UHF-RFID radio frequency identification technology launched has solved the problem of identification of vehicles in motion. The system uses radio frequency technology to perform high-accuracy, high-reliability, and fully-automatic identification of taxis, military, and police vehicles passing through each bayonet, which is conducive to improving the work efficiency of the public security traffic management department, improving the level of scientific management, and improving the overall The function of prevention and control capability.
The advantage of UHF-RFID radio frequency identification technology is that it uses frequency hopping technology and has a complete set of protocols, which ensures its outstanding anti-interference ability and makes it highly stable and reliable when multiple devices are working at the same time. Sex and intelligence. Each radio frequency identification card has a globally unique address code. This identification system uses this address code to correspond to the relevant information of taxis, military, and police vehicles, including the vehicle’s purchase year, license plate time, company, vehicle model, vehicle owner’s name, Information such as residential address, telephone number, ID number, driver’s license number, violation records, and even vehicle photos.
System composition
Radio frequency identification cards installed in the license plates of taxis, military and police vehicles;
Fixed identification readers installed at all entrances and exits and checkpoints;
Mobile (emergency) identification readers (or handheld readers) installed on motor vehicles;
Installed in the control center of the information center of the Public Security Bureau;
Main functions of the system
1. The radio frequency identification reader can read the license plate number, purchase year, license plate time, company, vehicle model, owner’s name, address, telephone number, ID number, Driver’s license number, violation record, vehicle photos and other information.
2. Information such as the license plate numbers, exit time, and entry time of all taxis and military vehicles at entrances and exits and checkpoints can be aggregated to the control center through the network in real time, and dynamically displayed on the screen. At the same time, the records are saved for relevant personnel to inquire. The inquirer can enter the license plate number to inquire about the outbound and inbound records, or enter the identification station number to inquire about the outbound and inbound traffic situation of a certain public security checkpoint within a certain period of time (the inquiry function can be added as needed).It is also possible to visually display the traffic flow of the public security checkpoints that need to be counted through graphs.
3. As long as you enter the relevant license plate number in the blacklist of the control center and click “Send Blacklist”, the blacklist of illegal vehicles such as stolen and fugitive vehicles can be transmitted to each identification station in time via the network. When a vehicle passes through the identification station, the identification station can alarm by means of sound, light, etc., to remind relevant personnel to arrest.
4. In emergency situations, mobile identification stations can be used to perform key surveillance on special intersections.
System features and advantages
1. High recognition accuracy.
2. Support higher traffic volume. Using frequency hopping technology, the effect of anti-interference between the same frequency is good, and it can identify multiple taxis, military and police vehicles at the same time.
3. Use the world’s only address to mark the identity of the vehicle, which is reliable, safe, and has no duplicate number.
4. Simple operation. The fixed identification station and control center can be unattended, and the operation interface is graphical, easy to learn; and the electronic ID does not require any operation by the driver.
5. Equipped with mobile identification station (handheld reader), which can be used under special circumstances.
6. The mobile identification station is very mobile and can exchange data with the control center in any place covered by the GSM network
7. The equipment cost is low. Effectively reduce the system cost.
8. The system function has strong scalability. For example, identification stations can be installed at major intersections in the urban area, and the approximate route of each taxi can be drawn in conjunction with an electronic map. The electronic ID card can be extended to any car, not just taxis, and it can monitor all vehicles in real time and improve the level of traffic management. An input device can also be installed on the electronic ID card to input passenger ID card and other information, and networked with the ID card query system of the Public Security Bureau, so that the information of passengers taking taxis can be counted to further enhance security.
