RFID electronic license plates help smart transportation construction

　　With the development of Internet technology and RFID technology becoming more and more perfect, "electronic license plates" came into being. "Electronic license plate" embeds RFID technology on the motor vehicle license plate, so that it can automatically recognize, transmit, and process vehicle related information. Electronic license plate is an application based on the subdivision, extension and improvement of passive UHF RFID radio frequency identification technology of the Internet of Things.

　　Its basic technical measures are: using the technical characteristics of RFID high-precision identification, high-accuracy collection, and high-sensitivity, an electronic license plate label is installed on the motor vehicle, and the RFID electronic license plate is used as the vehicle information carrier, and the When the authorized RFID radio frequency antenna and RFID identify the road section, the data on the electronic license plate of each motor vehicle is collected or written to achieve the purpose of comprehensive management of various traffic. This technology can break through the bottleneck of the original traffic information collection technology, realize the classified collection and accurate collection of vehicle traffic information, and grasp the key to the accuracy of the traffic control system information source.

　　It will solve the anti-counterfeiting and dynamic identification of vehicle identities from the source, providing a shortcut to smart transportation for cities. The electronic license plate stores information such as the license plate number in the radio frequency tag, which can automatically, non-contact, and non-stop vehicle identification and monitoring, which is an important part of building an intelligent transportation system. Intelligent transportation is in line with the rapid development and application of Internet of Things technology, cloud computing technology and information transmission technology. The future intelligent transportation will rely on a complete intelligent transportation Internet of Things system, and will further develop into intelligent transportation. Its goal is to change urban transportation. Get smarter. The first step in the construction of intelligent transportation is to popularize the use of automotive electronic license plates. Electronic license plates are an important foundation for building an intelligent transportation Internet of Things system.

　　RFID electronic license plate is an effective means of intelligent traffic management, which will greatly improve the drawbacks of traditional management methods in the transportation sector. RFID electronic license plates transmit vehicle code information and vehicle location to the traffic management system in real time through radio signals, obtain various electronic information and driving track information of vehicles, grasp traffic information in real time, and improve the information level of traffic management. The combined application of the Internet and RFID electronic license plate technology will bring about new changes in vehicle registration management, vehicle traffic management, and vehicle toll management. The specific manifestations are as follows:

　　(1) Vehicle registration management. Complete the automatic electronic identification of the vehicle, compare it with the information recorded in the background database, discover the authenticity, verify the inspection record (such as environmental protection inspection, insurance purchase, etc.), and the public security to inquire about the illegal vehicle. Carry out traffic monitoring based on vehicle recognition, build a traffic management mechanism based on electronic license plates, carry out refined traffic law enforcement operations, and severely investigate and deal with various traffic violations. Realize the digitization of certificates and improve the efficiency of inspection. The front-end automatically compares the inspection results through the passage information obtained in the background to realize the paperless, automated and intelligent pass management, and minimize fraudulent use, embezzlement and imitation.

　　(2) Vehicle traffic management. After the automatic electronic recognition of vehicles is completed, the functions of macro and partial control and path positioning of urban vehicles are carried out to produce linkages between people and vehicles, vehicles and vehicles, and vehicles and background. It can be reasonably matched with other traffic information detection methods (such as the aforementioned video collection) to achieve full coverage collection of vehicle information, and form a traffic information collection mechanism that fully and truly reflects the traffic state. Through the application of detailed traffic flow data, the central traffic is further enhanced The control system grasps the micro and macro traffic conditions, and then provides strong support for traffic guidance, control and decision-making.

　　(3) Vehicle toll management. When it comes to congestion charging, parking lot charges, traffic police fines, highway tolls, etc., in some roads and areas of the city, these charges are based on the internationally accepted back-end credit card payment method. Because the system adopts the most advanced and secure back-end electronic payment method, it realizes the real traffic "all-in-one card", including urban congestion charging and expressway free flow charging.
