Abstract

The embodiment of the present invention discloses a communication method for non-stop electronic toll collection. The method includes: obtaining the target distance between the vehicle equipment and the roadside unit; determining the target communication area corresponding to the vehicle equipment according to the target distance, and the roadside unit The side unit includes an antenna array forming at least one communication area, and each communication area has a priority set according to the target distance between the vehicle and the roadside unit, and the target communication area is an unoccupied communication area corresponding to the target distance The communication area with the highest priority among them; communicate with the on-board unit of the vehicle equipment through the target communication area. By adopting the embodiment of the present invention, it is possible to avoid car-following interference during communication between the roadside unit and the vehicle-mounted unit, and improve the reliability and accuracy of the communication between the roadside unit and the vehicle-mounted unit.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication method for non-parking 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 vehicle-mounted unit (On Board Unit, OBU) installed on the vehicle on this lane, completes the transaction and lifts the pole to make the vehicle that has completed the toll pass through the toll system . [0003] At present, when the OBU in a certain vehicle on the lane communicates with the RSU, the OBUs in other vehicles behind the vehicle may also be located in the communication area of ​​the antenna in the RSU, resulting in multiple vehicles communicating with the RSU at the same time to form car following Interference, and sometimes even lead t...
