基于故障树的分散自律调度集中车站子系统可靠性分析

分散自律调度集中车站子系统作为分散自律调度集中系统的关键子系统,具有从运行计划当中解析出列车进路、调车进路,接收人工列车进路、调车进路操作,并经过自律检查后发送给联锁设备去执行,以及采集行车信息等功能。因此,车站子系统的安全可靠运行直接关系着行车的安全和效率。以自律机不能向联锁设备发送进路命令为顶事件,建立系统故障树,并对该故障树进行定性和定量分析。

As the key component of the distributed and autonomous CTC（Centralized Traffic Control）,the station sub-system is responsible for many important work,such as getting train routes and shunting routes from planning,receiving manmade train routes and shunting routes,then sending those route commands to interlocking equipment to be executed after self-discipline examination,and collecting operation information and so on.So,the safe and reliable operation of the station sub-system is related to the train running safety and efficiency.The fault tree is set up by taking the case that autonomy machine can not send route command to interlocking equipment as top event,then the author carries out qualitative and quantitative analysis on the fault tree.
