ETC fee evasion vehicle screening method and device

Abstract

The invention provides an ETC fee evasion vehicle screening method and device. The method comprises the following steps: monitoring a vehicle signal sent by a passing vehicle in real time, judging whether the vehicle signal can be demodulated according to a preset demodulation code or not in a process of demodulating by utilizing a preset encoding and decoding standard, and quickly confirming whether the received vehicle signal is a shielding signal or not. Meanwhile, after the shielding signals are judged, license plate information of passing vehicles recognized and recorded by a license plate recognizer within the set time range of the interference moment is obtained to serve as suspected fee evasion vehicles, and vehicles illegally using the signal shielding device are screened out by recognizing the suspected fee evasion vehicles appearing at high frequency. According to the invention, shielding signals can be rapidly identified, corresponding suspected vehicles can be recorded andfee evasion vehicles can be screened out based on existing equipment of a portal system, the identification accuracy is high, the operation cost is low, and cheating behaviors by using a signal shielding device can be effectively inspected.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for screening ETC toll-dodging vehicles. Background technique [0002] At present, the toll stations on the provincial boundaries of expressways are cancelled, and the toll mode is changed to a segmented charging method, and the transaction is carried out directly through the ETC (Electronic Toll Collection electronic non-stop toll collection system) equipment, and through the reading of the on-board OBU (On board Unit) Write for real-time automated trading. The segmented billing method is to conduct separate transactions on roads, bridges, ramps and other toll road sections that vehicles pass through on the expressway. [0003] In the mode of trading with the help of ETC, a cheating method that gradually appears among ETC users is to place a WIFI jammer on the car. Since the WIFI jammer can emit interference signals covering the same microwave...

AI Technical Summary

Problems solved by technology

Since the WIFI jammer is used concealed in the car, the workload of inspecting toll-evading vehicles from a large number of driving videos and photos is huge, which has caused great difficulties in the inspection of toll-evading work.
