摘要: 基于DSRC协议的高速公路电子不停车收费(ETC)系统存在价格昂贵、通用性差的问题。为此,简化车载设备对错误信息帧的处理,采用微控制器设计并实现符合ETC复合消费交易应用流程规范的通信帧数据链路层及应用层信息的解析、封装。测试结果表明,程序移植到车载设备硬件系统后,系统运行稳定,时效性符合国家标准要求。

Abstract: Highways of Dedicated Short Range Communication(DSRC) protocol-based Electronic Toll Collection(ETC) system is expensive and has poor versatility. To solve these problems, it simplifies On-board Unit(OBU) error message frame processing, designs and implements communication frame’s analysis and packaging in data link layer and application layer using microcontroller, which is in line with the complex consumer transactions of ETC application process specifications. By porting program to OBU hardware system, test results show that the system is stable, and timeliness is in line with national standards.

Key words: Dedicated Short Range Communication(DSRC), Electronic Toll Collection(ETC), Roadside Unit(RSU), On-board Unit(OBU), Intelligent Transport System(ITS), abstract syntax notation
