System and method for vehicle driving path recognition based on vehicle electronic identification

technical field

The invention relates to a recognition system and method, in particular to a vehicle driving path recognition system and method based on automobile electronic identification, belonging to the technical field of intelligent transportation.

With the rapid development of my country's main roads and expressways, highways in various provinces have gradually formed a complex road ring network that is interconnected, and the problem of ambiguous paths has become increasingly prominent. Deployment and control pose great difficulties. In addition, since my country's expressway construction has adopted various forms of investment entities, and operation management involves different stakeholders, with the increase of people's travel needs and traffic volume, the call for provincial-level network toll collection has become increasingly louder. In order to protect the interests of car owners and investors and improve the operational efficiency and service quality of the highway network, since 2008, the national highway management department and highway operating companies have gradually implemented The highway network toll system based on ambiguous path recognition technology realizes the fairness and rationality of highway toll splitting.

At present, most expressway ambiguity path identification systems use composite pass cards (one RFID active electronic tag and one IC card). For example, "Technical Specifications for Expressway Ambiguity Path Identification System" (GDJTG/T J01-2013) and "Ambiguity Path Identification System and Its Method" (ZL200610036354.7) distribute a composite Pass cards, setting up a set of composite readers at the entrances and exits of toll stations, and setting up roadside launch equipment at highway junctions, etc., can realize the identification of vehicle paths. From the perspective of overall usage, this method not only has high operation and management costs, but also cannot solve the problems of composite pass card shielding and composite pass card interchange, which can easily lead to inaccurate identification of driving routes. In addition, the current domestic ambiguous route identification system based on the composite pass card can only realize the ambiguous route identification of expressways within the province, but cannot realize the ambiguous route identification between provinces.

Since 2013, the Ministry of Public Security, the Ministry of Industry and Information Technology and the National Standards Committee have organized research work on automotive electronic identification based on UHF RFID technology. At present, six national standards have been initially completed and are in the stage of public consultation; in addition, automotive electronic identification and RFID reader equipment with independent intellectual property rights are in the research and development stage, and have been initially demonstrated in Chongqing, Nanjing, Lanzhou and other cities application. In this context, the present invention proposes a vehicle driving path identification system and method based on automotive electronic identification, which solves the deficiencies of the prior art, reduces operating costs, and improves the accuracy of path identification.
