Abstract

The embodiment of the invention discloses a communication system, a communication method and a storage medium, and relates to the technical field of ETC (Electronic Toll Collection), the communicationsystem comprises a plurality of road side units (RSUs), wherein the plurality of RSUs are separated with each other, and an OBU is provided with a satellite positioning module for providing satellitepositioning information; a positioning information calibration device used for providing auxiliary positioning information; and a control device used for obtaining calibration positioning informationaccording to the satellite positioning information and the auxiliary positioning information, and then switching to the corresponding RSU and OBU for information interaction according to the calibration positioning information. The system has the advantages that the low power consumption of the to-be-positioned terminal can be ensured on the premise that the vehicle positioning precision is ensured; the RSU is switched in a non-inductive manner in an interaction process of the RSU and the OBU; under the condition of continuous coverage of the RSU, the problem of how to switch the mobile vehicle within each coverage range is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Electronic Toll Collection (ETC), and specifically relate to a communication system, a communication method, and a storage medium. Background technique [0002] In the related art, communication between the OBU and the RSU can be realized by disposing an On Board Unit (OBU) on the vehicle and disposing a Road Side Unit (RSU) on the side of the road. However, in related technologies, after the OBU establishes communication with an RSU, due to the limited communication distance of the RSU, when the vehicle gradually leaves the RSU, the communication signal between the RSU and the OBU will become weaker and weaker, and eventually the communication with the OBU will be disconnected. Inter-communication cannot meet the communication requirements between RSU and OBU. Contents of the invention [0003] Therefore, the embodiments of the present invention provide a communication system, a ...
