Non-stop electronic toll collection detection device

Abstract

The embodiment of the invention discloses non-stop electronic toll collection detection device. The detection equipment comprises a transceiver, a processor and a memory, a program instruction is stored in the memory; the processor is used for running the program instruction stored in the memory to execute the following steps: obtaining a target distance between the vehicle equipment and the roadside unit; determining a target communication area corresponding to the vehicle equipment according to the target distance, wherein the roadside unit comprises an antenna array forming at least one communication area, and each communication area is provided with a priority according to the target distance between the vehicle and the roadside unit, the target communication area is the communicationarea with the highest priority in unoccupied communication areas corresponding to the target distance; and communicating with an on-board unit of the vehicle equipment through a transceiver in the target communication area. By adopting the embodiment of the invention, the vehicle following interference during the communication between the road side unit and the vehicle-mounted unit can be avoided,and the reliability and accuracy of the communication between the road side unit and the vehicle-mounted unit are improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a detection device for non-stop electronic toll collection. Background technique [0002] At present, in order to reduce labor costs and improve charging efficiency, the Electronic Toll Collection (ETC) system has been greatly developed. In the ETC system, the roadside unit (Rate-Senor Unit, RSU) communicates with the on-board unit (OBU) installed on the vehicle in the lane, completes the transaction and raises the pole to make the vehicle that has completed the toll pass the toll system . [0003] At present, when the OBU in a vehicle in the lane communicates with the RSU, the OBU in other vehicles behind the vehicle may also be located in the communication area of ​​the antenna in the RSU, causing multiple vehicles to communicate with the RSU at the same time to form a follow-up Interference can sometimes even lead to communication errors or billing errors, resulting ...
