Introduction to license plate recognition technology The intelligent license plate recognition system, that is, the bayonet system adopts advanced, high-definition front-end image acquisition technology, and the effective resolution of the picture is several times higher than that of the conventional CCTV system, which solves the disadvantages of poor image quality of the front-end acquisition equipment of the system. After the system is completed, it will be able to realize real-time monitoring of road traffic related areas, automatically record and collect evidence for various traffic behaviors, automatically control the suspect vehicles, and intercept and perform functions at both ends of the entrance and exit duty points to meet the public security department's social security. Management and monitoring needs. The overall development trend of the bayonet system is toward the direction of the high-definition bayonet. At the same time, it is no longer used by a single traffic management department, but is used by the public security, traffic police, criminal investigation and other departments. Therefore, in order to improve the rapid response, handling and further prevention of criminal and public security cases, the establishment of the bayonet system has great practical significance for social security. The use of high-tech equipment to build a high-definition security bayonet system can not only record motorized and non-motorized vehicles and pedestrian information in a timely and accurate manner, but also keep track of the flow and status of motorized and non-motorized vehicles at each entrance and exit, the state of pedestrians, and the dynamic control of vehicles. Pedestrian dynamic monitoring, real-time alarm for all kinds of illegal vehicles, as well as stolen, escaping, suspected vehicles (stored in the "blacklist" library), and can also monitor the pedestrian status of key locations and stolen vehicles, vehicles Or the conditions of the vehicles entering and leaving the city and the route of travel by the criminals have improved the ability and combat effectiveness of the public security to crack down on crimes at the front line, thus providing a scientific and effective basis for the rapid detection of cases. Relying on the urban public security management information network system and the traffic command center management system, the main traffic management security card management system can be integrated into an organic comprehensive network platform to implement data sharing and provide remote services and Web queries for authorized users. The command center can call the information of each bayonet at any time. Application of license plate recognition technology in the investigation of deck vehicles On the GIS map, several areas are defined centering on the densely packed road sections of the front-end equipment. The time difference between the areas is used to cross-check the vehicles. If the vehicle number plate is the same, the vehicles with the same license plate color will pop up. The alarm box is identified by the manual review number plate. If the confirmation number plate is the same, the vehicle of the license plate is considered to be a deck suspect vehicle and is introduced into the deck suspect vehicle database. When the appearance of the two deck vehicles is different, you can use the vehicle management database to query the illegal deck vehicles, and then you can investigate and deal with them. However, when you encounter two identically designed deck cars, how to determine which one is illegal The deck car seems to have no way to start. Introduction to RFID technology RFID (RadioFrequencyIdenTIficaTIon) is a simple wireless system with only two basic components for controlling, detecting and tracking objects. The system consists of an interrogator (or reader) and a number of transponders (or tags). Originally in the technical field, transponders are electronic modules capable of transmitting information and replying information. In recent years, due to the rapid development of radio frequency technology, transponders have a new meaning and meaning, and are also called smart tags or tags. The reader (reader/writer) of the RFID electronic elevator certificate can perform wireless communication with the RFID electronic tag through the antenna, and can realize the reading or writing operation of the tag identification code and the memory data. A typical reader includes a high frequency module (transmitter and receiver), a control unit, and a reader antenna. At present, the local public security departments require taxis to strictly implement the installation of new-type solid-sealing devices in line with national standards. The new-type solid-sealing devices are non-removable screws. Once installed, the device can only be dismantled by breaking the number plate to prevent the illegal use of the number plate and other illegal activities. There are already cities using the most advanced RFID electronic tag technology to build a taxi electronic operation permit system, so that black taxis such as twin cars and deck cars have nowhere to hide. At the same time, it also implements the handling of taxi vehicles, driver qualification information anti-counterfeiting, management of vehicle operation and violation information, registration and punishment of driver violation information, and vehicle annual review records. Through the operation of the system, good practical management effects and social benefits are achieved, so that the functional management department can be informatized and efficient, and at the same time protect the vital interests of the taxi. However, RFID technology usually requires traffic law enforcement personnel to use the traffic law enforcement PDA handheld device to check the electronic label to verify the relevant operational qualifications of personnel and vehicles. The police station is responsible for controlling the suspected party and verifying its identity and other relevant information before it can investigate and deal with it. The illegal vehicles are enforced. Therefore, every time the investigation is conducted, a large number of personnel must be sent to check on the scene for each vehicle, such as the sea fishing. Considering the safety of law enforcement on the already-traveled roads, such law enforcement forms are still relatively rare. Advantages of combination of license plate recognition and RFID License plate recognition technology and RFID technology can be said to have their own strengths. Can we combine the two to complement each other? Through the sharing of data information, comparing the deck suspect vehicle data identified by the license plate recognition system with the RFID-based vehicle management information, the illegal vehicles can be determined very accurately, and combined with on-site law enforcement, the law enforcement efficiency can be greatly improved. Using the wide-area characteristics of the license plate recognition technology, the vehicle license plate data is processed in a certain area. This method can reduce the workload of manual retrieval, and compare the automation to obtain whether there is a black car or a deck vehicle in the area, and it can be intuitive. Know the license plate number of the deck vehicle, the time of occurrence, the driving area and the characteristics of the driver, and connect the above information with the public security, traffic law enforcement, vehicle law enforcement department information base to realize the illegal information sharing of the vehicle, which can be used by law enforcement agencies in the law enforcement process. Provide a good reference for the effective enforcement of law enforcement locations and enforcement time. Then in the field law enforcement can make full use of the uniqueness of RFID, more accurate positioning of illegal vehicles. Law enforcement officers can establish law enforcement checkpoints in places where taxis or black cars are more frequent, such as airports, railway stations, rail transit interchange hubs, etc., through the data query of the license plate recognition system, to know whether there are illegal vehicles, and then The passing vehicles are inspected to determine illegal vehicles. License plate recognition system and RFID vehicle system data flow in conclusion: The combination of these two technologies is fully achievable, and can analyze and process existing data, truly achieve information sharing, improve law enforcement efficiency, reduce law enforcement costs, and provide a good technology for a safe traffic environment. stand by.
