Abstract

The embodiment of the invention discloses an OBU (On Board Unit) and a vehicle positioning system based on BeiDou differential positioning. The OBU comprises a BeiDou positioning module, a first antenna, a master control module, a 5.8GHz DSRC (Dedicated Short Range Communications) module and a second antenna, wherein the BeiDou positioning module is connected with the first antenna for obtaining original BeiDou positioning data according to a preset period and sending the original BeiDou positioning data to the master control module; the master control module is used for sending the original BeiDou positioning data obtained by the BeiDou positioning module to any one RSU (Road Side Unit) on the basis of the 5.8GHz DSRC module after a confirmation result shows that the OBU is awakened by any one RSU; and the 5.8GHz DSRC module is connected with the second antenna for obtaining the accurate positioning data of the OBU. By use of the embodiment of the invention, the problem in the prior art that a vehicle can not be accurately positioned in a billing process due to overhigh power consumption is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of toll collection for toll roads, and in particular to an on-board unit OBU and a vehicle positioning system based on Beidou differential positioning. Background technique [0002] With the rapid development of the economy and the substantial increase in the demand for transportation, the traditional toll collection model has become a bottleneck restricting the traffic capacity of expressways. Electronic Toll Collection (ETC) system, as an effective means to solve this bottleneck, has become the main development direction of highway toll collection management. [0003] OBU (On Board Unit, OBU), also known as electronic tags, on-board equipment, is a mobile identification device with microwave communication function and information storage function, installed inside the vehicle (on the windshield or instrument panel) and A device that supports information exchange with roadside equipme...
