基于ETCS的ATO系统车地无线消息研究

Study on Train-wayside Radio Messages of ATO System Based on ETCS

近年来,欧洲铁路部门开始研究在ETCS的基础上叠加自动驾驶技术(ATO),以提高线路的运输能力和效率.基于ETCS的ATO系统车地无线通信采用了独立于ETCS的通道,也未沿用ETCS既有的无线消息和流程.介绍了基于ETCS的ATO系统总体架构,分析车地无线消息的定义及其应用原则,为国内自动驾驶技术的发展提供一定的参考.

Over recent years,European Union Agency for Railways(ERA)has set to make research on superimposing automatic train operation(ATO)technology on the ETCS in order to improve the carrying capacity and operation efficiency of railway lines.The train-wayside radio communication of the ATO over the ETCS system not only adopts the channels independent of that of the ETCS but also not follows the existing radio messaging and processes of the ETCS.The overall architecture of the ATO over the ETCS is introduced and the definitions of radio messages and the application principles are analyzed,which can provide some references for the development of automation train operation technology in Chinese railways.
