基于城际铁路CCS和高铁ATO系统TSRS的ATO技术探讨

Discussion on ATO Technology Based on CCS of Intercity Railways and TSRS of ATO System of High Speed Railways

列车自动驾驶(ATO)技术是提高运营效率的重要技术手段。2016年珠三角城际铁路首次实现CTCS-2级列控系统下的自动驾驶功能,2018年原中国铁路总公司组织实施京沈综合试验段高铁ATO列控系统试验,两者在不同级别列控系统下分别实现了自动驾驶。回顾城际铁路CTCS2+ATO技术体系中通信控制服务器的系统设计方案,比较分析高铁ATO系统临时限速服务器针对ATO功能实现方案的差异及背景原因,总结设备开发的思路变化及其带来的趋势影响,探讨高铁ATO技术的发展方向。

Automatic train operation(ATO)technology is an important technical means to improve the operation efficiency.In 2016,the automatic train operation function under CTCS-2 train control system was realized on the Pearl River Delta intercity railway for the first time.In 2018,the former China Railway Corporation organized and implemented the test on the ATO system in the integration test section of Beijing-Shenyang High Speed Railway.Automatic train operation was realized in both cases under the train control system of different levels.This paper reviews the system design scheme of the communication control server in CTCS2+ATO technology system of the intercity railway,comparatively analyzes the difference of temporary speed restriction server of ATO system of the high speed railway for ATO scheme,the corresponding background and reasons,summarizes the idea change of equipment development and trend impact brought by such a change,and discusses the development trend of ATO technology of the high speed railways.
