基于LTE和《RSSP-I铁路信号安全通信协议》的互联互通CBTC系统车地安全通信方案分析

摘要

In view of the characteristics of train/ground wireless communication in the interoperable CBTC system, the current problems of " Railway Signal Safety Protocol II/V1. 0" applied in some interconnected and interoperated urban projects based on TCP/IP are expounded. Combined with the advantages of LTE technology and " RSSP I/V1. 0", a new train/ground safety communication solution is proposed for the interoperable CBTC system. Finally, the feasibility of the new solution is analyzed from the safety point of view according to the requirements of relevant standards for the open communication system.%针对互联互通CBTC (基于通信的列车控制) 系统车地无线通信的特点, 阐述了目前基于TCP (传输控制协议) /IP (互联网协议) 的《RSSP-II铁路信号安全通信协议/ (V1. 0) 》在互联互通项目车地安全通信应用中存在的问题.结合LTE (长期演进) 技术和《RSSP-I铁路信号安全通道协议 (V1. 0) 》的优势, 提出了一种新的互联互通CBTC系统车地安全通信解决方案.最后, 根据相关标准定义的开放式通信系统要求, 对该方案进行了可行性分析.
