Abstract

The invention provides a vehicle-mounted unit OBU power adaptive adjusting method and equipment. The method comprises the steps that the power of the OBU is set as the first parameter in front of theentrance of electronic toll collection ETC so as to perform communication with an ETC antenna and complete the entrance transaction process; and the power of the OBU is set as the second parameter after passing the ETC entrance before sleep of the OBU so as to perform communication with a path identification antenna. According to the technical scheme, the functional characteristics of the CPC cardand the conventional OBU can be greatly integrated, the convenient and rapid characteristics at the toll road entrance and exit can be reserved for the OBU vehicle owner, and the marking success rateon the path identification road can also be enhanced. Compared with other schemes, the cost is low and accurate recording of the entrance and exit and path information of the toll road can be completed without performing upgrading and reconstruction of the OBU, the antenna and even the whole system.

Description

technical field [0001] The present invention generally relates to the field of intelligent transportation, and more particularly relates to the field of adaptively adjusting the power of an on-board unit (OBU). Background technique [0002] At present, the expressway network toll collection system mainly includes the non-stop toll collection system (ETC) and the ambiguous path identification composite pass card (CPC). The main function of ETC is to communicate through the dedicated short-range communication DSRC between the on-board electronic tag installed on the vehicle windshield and the path identification antenna on the ETC lane of the toll station. Then, use computer networking technology to carry out background settlement processing with the bank, so as to achieve the purpose of paying road and bridge tolls without stopping when vehicles pass through road and bridge toll stations. [0003] When the owner has installed the OBU, enter the high-speed lane through the ET...
