摘要
在城市轨道交通信号系统中,基于通信的列车控制系统(CBTC)是目前国内运营线路的主要系统。对于列车定位及车地通信正常的CBTC列车而言,若区段故障,降级列车安全防护包络蔓延至故障区段,则会使得联锁认为区段被占用,将破坏进路防护信号机的自动开放条件。结合苏州3号线唯亭站发生的区段特殊故障实际案例,当ATS界面显示棕光带、紫光带交替闪烁故障后,分析列车安全防护包络与区段故障的影响,为运营行车管理提供相应的应对措施和处理方法,提升行车指挥效率。
In the signaling system for urban rail transit,the Communication Based Train Control(CBTC)system is the main system for operating lines in China.For CBTC trains with normal train positioning and train-wayside communication,if a section fault occurs and the safety protection envelope of the downgraded train spreads to the faulty section,the faulty section will be considered by the interlocking system as occupied,so that the automatic clearing conditions of the route protection signal will not be met.Considering an actual case of section fault at Weiting Station on Suzhou Rail Transit Line 3,this paper analyzes the impacts of the protective envelope for train safety and the section fault when the brown and purple light strips are lit alternately to display the fault on the ATS interface.It also provides corresponding response measures and handling methods for operation and train management,which improves the efficiency of train operation commanding.
