摘要:
CTCS-2(中国列车运行控制系统2级)+ATO(列车自动运行)系统应用于市域(郊)铁路时,存在线路折返能力不足的问题。以上海机场联络线为研究对象,对CTCS-2+ATO制式下的列车折返作业进行分析,在国内首次提出CTCS-2+ATO下3 min内完成列车自动折返的技术方案。该方案建立了CTCS-2+ATO下的列车自动折返流程,并提出列车自动折返的信号-车辆接口方案。仿真验证结果表明:该方案的列车自动换端时间在20 s以内,列车自动折返全过程可在3 min内完成。

When the CTCS-2 (Chinese Train Control System Level 2)+ATO (automatic train operation) system is applied to urban (suburban) railways, the problem of insufficient train turn-back capacity comes out. In this paper, based on Shanghai Rail Transit Airport Link Line, the current situation of train turn-back under CTCS-2+ATO system is analyzed, and a technical scheme of automatic turn-back within 3 min under CTCS-2+ATO system is proposed for the first time in China. In the scheme, the automatic turn-back process is established and a signal/vehicle interface scheme is put forward. Simulation results show that the automatic train switching of the scheme is within 20 s, and the whole process of train automatic turn-back can be completed within 3 min.
