ETC vehicle automatic supervision system

Abstract

The invention discloses an ETC vehicle automatic supervision system. The system comprises an ETC gantry, a microwave antenna, a license plate automatic recognizer, a lane controller and an automatic railing. the microwave antenna is installed on the ETC gantry and used for being connected with and communicating with a vehicle-mounted electronic tag, obtaining a first license plate number stored inthe vehicle-mounted electronic tag and transmitting the first license plate number to the lane controller; the license plate automatic recognizer is used for obtaining an image of a second license plate number of a vehicle and transmitting the image to the lane controller, and the second license plate number is a license plate number suspended by the vehicle; and the lane controller is used for processing the image of the second license plate number, comparing the image with the first license plate number, and controlling the automatic railing to open if the image is consistent with the firstlicense plate number. According to the ETC vehicle automatic supervision system, the distinguishing of vehicles with or without vehicle-mounted electronic tags on the lane is realized, the running state of the vehicles on the lane can be truly reflected, the fee evasion behavior of the vehicles on the ETC lanes is effectively prevented, and the order of the transportation market is maintained.

Description

technical field [0001] The invention belongs to the technical field of ETC, and more specifically relates to an ETC vehicle automatic supervision system. Background technique [0002] Expressway non-stop toll collection refers to the technical means of electronic payment of tolls through the microwave communication link established by the on-board electronic label in the vehicle and the microwave antenna on the ETC mast when the vehicle passes through the ETC lane arranged by the toll station. [0003] In practical application, the problem of following-vehicle interference often occurs, resulting in inconsistencies between toll-paying vehicles and releasing vehicles. For example, when two vehicles drive into the ETC lane, if the vehicle in front is not equipped with a vehicle-mounted electronic tag or the sensitivity of the vehicle-mounted electronic tag is lower than that of the vehicle in the rear, resulting in a successful transaction for the vehicle in the rear and no tr...

Problems solved by technology

However, it still cannot solve the situation that the vehicle in front is not equipped with on-board electronic tags. At the same time, the requirements for the consistency of on-board electronic tags are too high, which will increase production costs.
