Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The main solution of the embodiment of the present invention is:

[0044] Due to the differences in the OBU hardware loaded on different vehicles, the distance between the microwave radio frequency signals recognized by the on-board OBU and the RSU at the road end is different. Due to the OBU of the vehicle behind, the lane cannot be lifted correctly, and the vehicle behind cannot pass through the gate of the toll station normally.

[0045]The present invention provides a solution, by detecting that the vehicle enters the ETC communication area of ​​the high-speed toll station, judge the real-time distance between the vehicle and the vehicle in front; when the real-time distance between the vehicle and the vehicle in front is less than or equal to the preset first distance , the communication function of the o...

Abstract

The invention discloses a method for preventing ETC misreading. The method comprises the steps that whether the real-time distance between a vehicle and a front vehicle is smaller than or equal to a preset first distance or not is judged when it is detected that the vehicle enters an ETC communication area of a highway toll station; when the real-time distance between the vehicle and the front vehicle is smaller than or equal to a preset first distance, the communication function of the vehicle-mounted ETCOBU of the vehicle is limited, so that the road end RSU in the ETC communication area cannot identify the vehicle-mounted ETC of the vehicle; and when the real-time distance between the vehicle and the front vehicle is greater than the preset first distance, or the front vehicle leaves the ETC communication area, the communication function of the vehicle-mounted ETC OBU of the vehicle is recovered, so that the road end RSU identifies the vehicle-mounted ETC of the vehicle. The invention also discloses a device for preventing ETC misreading, a vehicle-mounted OBU and a computer readable storage medium. According to the method, the ECT misreading phenomenon caused by the fact that the distance between the two vehicles is too short can be prevented.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for preventing ETC misreading, a vehicle-mounted OBU and a computer-readable storage medium. Background technique [0002] ETC (Electronic Toll Collection) refers to the non-parking electronic toll collection system, which is mainly composed of automatic vehicle identification system, central management system and other auxiliary facilities. Among them, the automatic vehicle identification system is composed of OBU (On board Unit, on-board unit), RSU (Road side unit, road side unit), loop sensor and so on. The OBU stores the relevant information of the vehicle, which is generally installed on the front windshield of the vehicle, the RSU is installed next to the ETC toll station, the loop sensor is installed under the ground of the driveway, and the central management system stores a large amount of vehicle and owner information. The management system i...
