Talk About the Significance of Using License Plate Recognition System in National Expressway Toll Ne

Network toll collection system is an important part of expressway information construction. Most of the previous expressway network toll collection systems used the form of pass card, that is, mark the corresponding vehicles through the pass card, and then charge at the exit of the expressway according to the vehicle entrance information recorded in the pass card. However, in this way, the vehicle number is incomplete and easy to enter incorrectly; Changing cards between different vehicles, loss of pass cards and large number of pass vehicles are easy to cause vehicle backlog and affect the rapid passage of vehicles. How to use high and new technology to improve the level of road management has attracted extensive attention. The most effective method is to introduce the license plate recognition system into the charging system. The entrance automatically recognizes the license plate number, extracts the binary image of the license plate area and writes it into the pass card; The exit will automatically recognize the license plate information again and match it with the license plate number and the binary image of the license plate area recorded on the card. In case of any mismatch, the alarm will be started, and the whole process billing or other special charging processing will be carried out. The role of license plate recognition system technology in Expressway Toll Collection: first, prevent the loss of pass cards and accurately locate the flow direction of pass cards. Through the identification and archiving of vehicle license plate numbers by the license plate recognition system, the expressway related toll collection system can automatically record the accurate flow direction of all pass cards. For pass cards that cannot be recovered, the vehicles receiving the cards can be listed as blacklisted vehicles, Once the vehicle enters the system again, it will be intercepted. 2、 Check the blacklist vehicles. By using license plate recognition, the vehicles in the blacklist database can be automatically checked. The blacklist vehicles include vehicles wanted by the public security, vehicles with card flushing records, vehicles in arrears, vehicles without return of pass cards and other vehicles with criminal record. 3、 It can replace the lane monitoring equipment, and the license plate recognition system can provide analog video image signals for monitoring the situation of vehicles. The depth of field of view of the provided video image can fully meet the needs of lane monitoring, and can also provide a clear still image of vehicles to the lane control machine, which is convenient for toll collectors to observe the vehicle situation, It successfully solves the problem that the imaging of conventional Lane monitoring equipment is disturbed by sunlight and headlights.
