Abstract

The present invention provides a method and device for screening ETC toll evading vehicles. The method monitors the vehicle signals sent by passing vehicles in real time, and judges whether the vehicle signals can be used in the demodulation process according to the preset encoding and decoding standards. Preset modulation, decoding and demodulation to quickly confirm whether the received vehicle signal is a shielded signal. At the same time, after judging the shielding signal, obtain the license plate information of the passing vehicle identified and recorded by the license plate recognizer within the time range set at the time of interference as the suspected toll-evading vehicle, and screen out the Vehicles using signal jammers illegally. Based on the existing equipment of the gantry system, the invention can quickly identify shielding signals, record corresponding suspected vehicles and screen out toll evading vehicles, has high recognition accuracy, low operating cost, and can effectively check cheating behaviors using signal shielding devices.

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...
