Abstract

The invention discloses an automatic fare collection method and a device thereof for eliminating interference from adjacent channels in an electronic automatic fare collection system, relating to the field of electronic automatic fare collection. The method comprises: providing a plurality of on-bus station wireless signal receiving antennae to detect an on-bus station position signal; analyzing the obtained on-bus station position signal; according to the analysis and calculation result, calculating a lane on which the on-bus station is positioned; controlling the roadside station of the corresponding lane to charge the on-bus station; and preventing the roadside stations of other lanes from charging the on-bus station. The invention ensures that RSU (Remote Subscriber Unit) only processes the OBU (On-Bus Unit) of the lane so as to avoid mistaken payment deduction.

Description

Technical field [0001] The present invention relates to the field of electronic automatic toll collection (ETC, Electronic Toll Collection), in particular to a technology for solving adjacent channel interference in multi-lane applications in the field of automatic electronic toll collection of vehicles. Background technique [0002] With the rapid development of highways and intelligent transportation, traditional manual toll collection systems are increasingly unable to meet people's requirements for fast, accurate, energy-saving and safe highway toll collection. In this way, a new generation of vehicle electronic automatic toll collection system is gradually being developed. It is loved by people for fast, accurate, energy-saving and safe, and gradually occupy the market. [0003] In 2007, the country formulated a national standard based on the 5.8GHzDSRC system, and highways in Beijing, Shanghai and other places began to be gradually promoted and applied. Such automatic toll ...
