1. System introduction
Automobile electronic identification, also known as electronic license plate, is an electronic ID card that combines ordinary license plate and UHF radio frequency identification technology.
The automobile electronic identification system is to install an RFID electronic tag for storing car identification data on the inside of the front windshield of the vehicle, and communicate with the high-speed read-write device of the electronic license plate laid on the urban road section. The data can be read and written to realize automatic, non-contact, and non-stop vehicle identification and monitoring. At the same time, combined with the original traffic information collection and traffic management platform, it can fully meet the requirements of the Ministry of Public Security of “real-time monitoring, networked control, automatic alarm, rapid response, science, efficiency, and information sharing”, and realize true digitization, intelligence, Refined traffic management.
2. System advantages
※Compatible with national standards and industry standards
It complies with the national standard of GB/T 29768-2013 “Information Technology Radio Frequency Identification 800/900MHz Air Interface Protocol” and the “General Technical Requirements for Motor Vehicle Electronic Identification” formulated by the Ministry of Public Security.
※Good security and confidentiality
It adopts advanced symmetric encryption algorithm and SM7 or SM4 encryption algorithm approved by the national password management department to meet the second level security requirements of 5.2 in GM/T 0035.1-2014.
※Fast transaction speed
Relying on the technical characteristics of high RFID recognition accuracy, accurate information collection, and high system stability, it supports car driving speeds exceeding 180 km/h.
※High transaction power
Adopting advanced multi-label recognition algorithm, the system identification success rate is higher than similar products.
※Strong anti-interference ability
Using carrier cancellation technology, stronger anti-interference ability.
Three, working principle
As the basic information carrier for the electronic collection of vehicle information by the public security department, the automobile electronic identification system can automatically collect the attribute information, location information and status information of the passing vehicles through the read-write device installed in the lane, which fundamentally eliminates road traffic management. The “blind spots” in time and space have comprehensively expanded the monitoring period and scope of traffic management, and the big data generated can be used to improve the intensity of urban traffic management, truly realize digital and intelligent traffic management, and become a smart city. The construction of the smart transportation system provides key data services.
4. The main technical principles are as follows:
※Information carrier:
Adopt the unmodifiable RFID tag of the global border as the electronic vehicle logo information carrier. It is uniquely matched and bound with the vehicle entity number plate, and the storage space is partitioned, including the license plate information area, the basic vehicle information area, and other information recording areas. The information in different partitions is open or AES encrypted. The license plate information area and The basic information area of the vehicle only supports read operations after being written once, and other information recording areas support read and write operations to meet the needs of different users for different types of information.
※Double base recognition
In the process of vehicle identity recognition, the reader obtains the electronic vehicle logo information provided by the RFID tag and the image processing information obtained by the bayonet system for matching recognition. The identification information can be fuzzy matching only for the number plate information, and if necessary, the basic vehicle information can be extracted for precise matching to achieve high-accuracy recognition.
※Road network collaboration:
Based on RFID communication, the electronic car logo and the base station, the base station and the car trim terminal. The electronic vehicle logo and the vehicle-mounted terminal carry out two-way and multi-directional intercommunication between the equipment. The information source formed by this can be connected to the road network system through the base station, and the man-machine interface can be established through the vehicle trim terminal, thereby forming A, vehicle, locomotive, and Internet. Information coordination completes the closed-loop process of information collection, analysis, processing, and feedback, and realizes diversified and intelligent safety management functions for vehicles.
