etc lane vehicle detection system and detection method

Abstract

The invention relates to an ETC lane vehicle detection system and a detection method. The ETC lane vehicle detection system comprises a lane host, a fixing rack positioned on an ETC lane, and a laser scanning sensor and a license plate identification device electrically connected with the lane host, the laser scanning sensor and the license plate identification device are both fixed on the fixing rack, the laser scanning sensor is provided with a first laser port and a second laser port, the first laser port and the second laser port are both arranged face to the ETC lane, and the first laser port and the second laser port are arranged along the length direction of the ETC lane. According to the ETC lane vehicle detection system and the detection method, the reconstruction of the three-dimensional contour of the vehicle is realized via the laser scanning sensor, the license plate identification device, and a lane controller, accurate model identification is realized, even a large vehicle installs an OBU of a small vehicle, the large vehicle cannot pass since vehicle information is not in accordance with OBU information, fee evasion behaviors of the vehicles on the ETC lanes can be prevented, the benefit of highway owners is maintained, and the order of the traffic transportation market is maintained.

Description

technical field [0001] The invention relates to the technical field of an ETC non-stop charging system, in particular to an ETC lane vehicle detection system and detection method. Background technique [0002] The non-stop charging system ETC (Electronic Toll Collection) is currently the most advanced road and bridge toll collection method in the world, through the connection between the on-board unit OBU (On Board Unit) installed on the vehicle windshield and the microwave antenna on the ETC lane of the toll station Microwave dedicated short-range communication, using computer networking technology to carry out background settlement processing with banks. Different vehicles have different wear and tear on the road. Different tolls are charged according to different vehicle classifications, and the obligations of different road users are reasonably allocated. However, in order to reduce transportation costs, large vehicles are currently trying to replace the OBU of small ca...

AI Technical Summary

Problems solved by technology

However, in order to reduce transportation costs, large vehicles are currently trying to replace the OBU of small cars on large vehicles, causing extremely bad social impact. If this malicious method of evading fees cannot be effectively curbed, with the large-scale promotion of ETC in the future, This toll evasion behavior will seriously damage the interests of expressway owners and disrupt the order of the transportation market
