摘要
地铁信号系统是地铁系统的中枢神经,同时也是提高地铁运营水平的重要保障。在分析信号系统功能及故障类型的基础上,划分了设备重要度水平。通过地铁信号系统Petri网5大对象子类框架的搭建,分析研究了信号系统重要设备发生故障的情况下,系统各子类的动态Petri网可靠性模型。
Subway signal system is the central nervous system of metro,at the same time,it is the important safeguard of the metro operation standard improvements.This paper divided the important degree of the system based on the analysis of system function and system fault type.Constructing the metro signaling Petri Net framework of five sub-nets,the paper researches the dynamic sub-nets reliability model under the condition of the important equipment signal system failure.
