ETCS体系发展技术分析

欧洲列车运行控制系统(ETCS)体系规范基线3(3.6.0)版本于2016年正式发布,并通过TEN-T,NGTC及Shift2Rail等项目不断发展完善。近年来,该体系在保持互联互通特点的基础上扩展了道口关联控制等应用场景,通过优化制动模型提升了系统性能,发布了提升自动化等级的规范集,并保持了对既有体系的兼容性。文章对ETCS体系规范的更新进行分析,从发展过程、系统架构、功能变化、技术趋势等方面梳理变更要点并总结发展趋势,希望对我国CTCS技术体系的发展及CTCS和ETCS的互联互通提供借鉴。

Technical Analysis of the ETCS Architecture Development

Specifications of European train control system(ETCS)were released in 2016 as baseline 3(3.6.0),and it has been continuously developed and improved through projects such as TEN-T,NGTC and Shift2Rail.In recent years,on the basis of maintaining the characteristics of interoperability,the system has defined new functions,including level crossing control,improved braking model and automatic train operation.At the same time,it keeps the compatibility to the existing system.In this paper,it analyzed the updates for the process,architecture,functions and technology trends.Hopefully,such analysis could be helpful for the CTCS development,and the interoperability between CTCS and ETCS.
