The embodiment of the invention provides an adjacent channel interference prevention method and device based on satellite differential positioning, wherein the method comprises the steps that an RSU issues the broadcast information to search for the nearby OBUs; the OBU calculates the accurate positioning of the vehicle to which the OBU belongs through the original satellite positioning data acquired by the OBU and the satellite differential calibration data acquired from the broadcast information of the RSU; the OBU receives the broadcast information of the RSU and sends the basic information of the OBU to the RSU, wherein the basic information carries the calibration positioning data of a vehicle to which the OBU belongs; the RSU receives the calibration positioning data carried in basic information replied by the OBU, and determines that the OBU belongs to a lane to which the RSU belongs, and if the distance between the OBU and the RSU is smaller than a preset distance, the RSU judges that the vehicle to which the current OBU belongs is a vehicle to be transacted; and the RSU establishes a link with the OBU for communication and transaction, so that the problem of the adjacent channel interference caused by the unreasonable design in the prior art is solved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of non-stop tolling on expressways, in particular to a method and device for preventing adjacent road interference based on satellite differential positioning. Background technique [0002] With the rapid development of our country's 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...
