基于车-车通信的列车自主运行系统应用与展望

Application and prospect of train autonomous operation system based on vehicle-to-vehicle communication

近年来,国内许多城市轨道交通全自动运行线路的建设呈快速增长趋势。基于车-车通信的列车自主运行系统作为新一代列车运行控制系统,具有安全、高效、灵活、经济、易部署等特点,系统的功能和性能更优、架构更精简。文章基于国家“十四五”规划中持续推进智慧城市轨道交通建设的发展纲领,以深圳地铁20号线为例,分析TACS系统的运行原理、系统架构、系统优势等关键技术特征,剖析现有TACS系统发展现状及存在的不足之处,同时论述该系统的未来发展前景,为TACS系统在运营场景下的开发与应用提供参考和借鉴。

In recent years,the construction of fully automated operation lines of many domestic urban rail transit shows a rapid development trend.As a new generation of train operation control system,the train autonomous operation system based on vehicle-to-vehicle communication has the characteristics of safety,efficiency,flexibility,economically sound,easy deployment,etc.The system has better performance and more functions,and a simpler architecture.Based on the development program of continuously promoting the construction of intelligent city rail transit in the national"Fourteenth Five-Year Plan",this paper takes Shenzhen metro line 20 as an example to analyze the key technical characteristics of TACS system,such as its operating principle,system architecture,system advantages,etc.,analyze the current development situation and existing shortcomings of the existing TACS system,and discuss the future development prospects of the system,providing reference for the development and application of TACS system during market operation.
