Problems solved by technology

[0004] The RSU is usually installed on the gantry above the ramp of the toll station. The size and distance of the communication coverage area are controlled by adjusting the pitch angle of the antenna. The adjustment process is very complicated.
The existing electronic non-parking toll collection system and its implementation method use one antenna to correspond to one OBU transaction processor, and each OBU transaction processor can only conduct transactions with one OBU, and can only conduct transactions with the next OBU after the previous transaction is completed. Transaction, the transaction speed is slow, and cannot meet the requirements of high speed and multiple motor vehicles passing at the same time

Embodiment Construction

[0018] Based on the existing OBU transaction processor in the RSU, one OBU transaction processor corresponds to one antenna, and each OBU transaction processor can only trade with one OBU, and can only trade with the next OBU after the previous transaction is completed. The transaction speed is slow and cannot meet the requirements of high vehicle speed and simultaneous passage of multiple motor vehicles. The embodiment of the present invention provides an OBU transaction processor, which can realize that multiple OBU transaction processors share one antenna, that is, multiple OBUs perform transaction processing at the same time, and share a DSRC channel time-sharing, which can shorten the transaction time of multiple OBUs, It can greatly improve the transaction processing and application performance of the RSU system.

Abstract

The invention relates to an electronic toll collection (ETC) system, and discloses an on board unit (OBU) transaction processing device and an OBU transaction processing method capable of enabling a plurality of OBU transaction processors to share an antenna so as to greatly shorten the time of a plurality of OBU transactions in the ETC system. The OBU transaction processing device comprises a parallel coordinator and at least one OBU transaction processor, wherein the parallel coordinator is used for selectively connecting the plurality of OBU transaction processors to a dedicated short-range communication (DSRC) channel in turn when the shared DSRC channel is available; and when each OBU transaction processor is connected to the DSRC channel, the OBU transaction processor transmits transaction instructions to be transmitted to an OBU through the DSRC channel.

Description

technical field [0001] The invention relates to an ETC system, in particular to an OBU transaction processing device and method. Background technique [0002] The free flow system is an intelligent transportation comprehensive solution that uses active RFID electronic tags as the carrier of vehicle information, combined with modern technologies such as data communication technology, automatic control technology, computer network technology, and information release technology. The system can be used for urban congestion management and a barrier-free charging system for vehicles to travel freely, also known as Multi-Lane free flow (MLFF). [0003] The free-flow system adopts Dedicated Short Range Communication (DSRC) technology to complete the two-way communication between the Roadside Unit (RSU) and the On Board Unit (OBU), and conducts security authentication and consumption wirelessly. Withholding money and realizing non-stop toll collection greatly speeds up the passing s...
