1, function introduction of traffic police RFID vehicle identification management system
The system is suitable for the inspection of bad phenomena of vehicles, such as the inspection of vehicles with fake or fake plates, the inspection of vehicles violating regulations and hit-and-run vehicles, the inspection of other types of vehicles violating regulations, and other extended functions.
Install an active remote identification card with vehicle information and owner information behind the windshield of a legal vehicle, and the management platform and data server will download the corresponding information to each inspection system (PDA remote card reader) in time; On the premise that all legal vehicles are equipped with long-distance identification cards, the handheld inspection system directionally receives electronic information and displays corresponding vehicle information, and law enforcement officers compare the physical characteristics of vehicles with the displayed vehicle information, and those that do not match or cannot receive electronic information are fake and shoddy vehicles; The on-board inspection system or the fixed inspection system automatically compares the physical characteristics and electronic information of the designated vehicle through the image recognition system and the electronic information receiving system. If the information is inconsistent or the system only receives image information, it is a fake or counterfeit vehicle. The system will immediately give an alarm through voice and digital display, and law enforcement officers can conduct interception inspection in time or notify law enforcement officers at the next intersection to conduct interception inspection.
A) inspection of stolen and smuggled vehicles
Enter the information such as the license plate number of the stolen vehicle into the inspection system through the management platform and join the blacklist. If the stolen vehicle continues to use the original license plate number and enters the inspection scope, the system can immediately monitor and alarm; If you don't use the original license plate number, it will be considered as a fake, deck car and will be identified and intercepted. Further examination of the characteristics of the car can determine whether it is a stolen car. For smuggling cars, because they can't get a legal license, they can only be fake, and the deck cars will also be seized in time.
B) Check illegal and hit-and-run vehicles.
Information such as license plate numbers and violation records of illegal and hit-and-run vehicles are entered into the inspection system through the management platform and blacklisted. When this kind of vehicle enters the inspection range, the system can monitor it immediately, prompting the vehicle characteristics, violation of regulations, hit-and-run and so on, and law enforcement officers can intercept it immediately.
C) Check other types of illegal vehicles.
The system can also input the information of scrapped vehicles, vehicles that have not been inspected annually, vehicles that owe taxes and other vehicles and their owners. Enter the management platform and add them to the blacklist. When these vehicles enter the inspection scope, the system can immediately monitor and prompt the characteristics of the vehicles and their violations, and law enforcement officers can immediately intercept and enforce the law.
D) other extended functions
The system provides a variety of functional interfaces, which can easily increase the functions needed for traffic management and public safety, such as highway toll collection, access control management in residential areas and parking lots, vehicle driver identification and so on. Combined with GPRS technology, it can realize remote vehicle status monitoring, remote flameout of stolen vehicles, automatic notification of vehicle violations and other functions.
2. The working principle of traffic police RFID vehicle identification management system.
The core technology of vehicle identification management system is automatic identification and automatic discrimination of vehicles. Automatic Vehicle Identification System (AVI) based on active RFID technology includes vehicle-mounted radio frequency tag, fixed base station AVI and handheld base station AVI system. Here we introduce the handheld method, and the schematic diagram is as follows: handheld AVI system
In some applications, such as public security criminal investigation, road patrol, important conference security, etc., it is necessary to equip with a handheld AVI system, which can start and stop at designated roadside at any time to conduct surprise inspection and identification of passing vehicles. The handheld AVI system keeps communication or exchanges data information with the system control center through GPRS. If you need to report the location of the handheld AVI system, you only need to transmit the geographical location of the mobile station to the command center through GPRS. In some applications, you can also use a simple mobile detection device (ML-M4000P PDA handheld card reader). Inspectors can use PDA card readers to check passing vehicles in some narrow areas. The PDA reader will download the vehicle information in advance, and once it reads the illegal information, it will immediately call the police.
3. System composition
The system mainly consists of a long-distance 2.4G anti-disassembly active electronic tag, a handheld PDA card reader and background management software:
Electronic tag is an active electronic radio frequency card, with a power of about110,000 watts and ultra-low power consumption. Its memory can be used to store all kinds of information, including vehicle model, license plate number, owner's related information and so on. It is a perfect car ID card and credit card.
Handheld PDA can read electronic tags and contact information management center through GPRS to display information in real time.
Background management software is specially designed for vehicle identification management.
