基于RSSP-Ⅱ的城市轨道交通ATS与VOBC间安全通信研究

摘要

The data communication between the automatic train monitoring (ATS) and the vehicle on-board controller (VOBC) is in open network environment, which has higher requirement on the reliability and timeless of communication between devices. To satisfy the performance of communication, this article combined with the railway signal safety communication protocol(RSSP-Ⅱ), discussed the communication framework between ATS and VOBC, designed and implemented communication interface module for ATS and VOBC. The communication module was tested and verified by the ATS simulation platform.%列车自动监控系统(ATS)与车载控制器(VOBC)之间的数据通信处于开放式网络环境下,对设备间通信的可靠性、时效性提出了较高的要求.为了满足其通信性能,结合铁路信号安全通信协议(RSSP-Ⅱ),论述ATS与VOBC间的通信架构,设计实现了ATS与VOBC交互的通信接口模块,通过建立ATS仿真平台,对该通信接口进行了测试,验证了其功能实现.
