Problems solved by technology

[0005] In view of this, the embodiment of the present invention provides a method for trading with OBU and RSU to solve the problem of the existing ETC lanes as a whole based on the current position of the motor vehicle as the basis for establishing a transaction communication link with the OBU. The traffic efficiency is low, and the overall unobstructed effect of the lane is not good

Embodiment Construction

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0064] figure 1 It is a flow chart of the method for trading with OBU provided by the embodiment of the present invention. This method can be applied to RSU. Refer to figure 1 , the method can include:

[0065] Step S100, acquiring a plurality of OBU signals sent by the OBU;

[0066] The OBU here can be an OBU in the ETC lane to which the RSU belongs, and the RSU can obtain the OBU signal (such as VST) sent by the OBU by sending a communication command (such...

Abstract

The embodiment of the invention provides a method for communicating with an OBU and an RSU. The method comprises the steps of obtaining multiple OBU signals sent by the OBU, determining the OBU coordinates and acquiring time corresponding to the multiple OBU signals, determining the OBU speed and OBU coordinates corresponding to the OBU according to the OBU coordinates and acquiring time corresponding to the multiple OBU signals, and carrying on transactions with the OBU if the OBU coordinates corresponding to the OBU are legal and the OBU speed and OBU coordinates corresponding to the OBU meet preset transaction communication conditions. According to the method for communicating with the OBU and the RSU, the speed and the current position of a motor vehicle serve as the basis for establishing a transaction communication link with the OBU, the problems of car flowing and byway interference can be effectively solved, and overall traffic efficiency of an ETC lane is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, and more specifically, relates to a method for trading with an OBU and an RSU. Background technique [0002] ETC (Electronic Toll Collection, non-stop charging system) is a kind of intelligent transportation system. ETC mainly includes RSU (Road Side Unit, road side unit) and OBU (On board Unit, vehicle-mounted unit). RSU is set on the ETC lane. The OBU is installed on the motor vehicle; after the motor vehicle enters the ETC lane, the RSU will use DSRC (Dedicated Short Range Communication) technology to communicate with the OBU to complete non-stop charging. [0003] At present, the way for OBU and RSU to establish a transaction communication link is mainly: RSU sends communication signals such as BST to OBU to locate OBU. When the positioning position of OBU reaches the predetermined position of ETC lane, it means that the motor vehicle has reached the ETC lane. at the prede...
