摘要:

地铁联锁系统具有高安全性的特点,通常采用动态故障树分析方法分析联锁系统可靠性,但是随着故障树的增长,马尔可夫状态转移图就会变得非常巨大,相应地会带来计算度的复杂。对于一个热备件的地铁联锁系统而言,运用共因失效原理能够简化分析过程,避免因建立动态故障树、转化马尔可夫图和矩阵计算而带来的复杂过程。仿真证明此方法是切实可行的。

Abstract:

In terms of the high security characteristics of the underground railway interlocking system, dynamic fault tree analysis method is often used. But the increasing of computational complexity is brought by the increasing of the fault tree. This paper uses common cause failure factor replacing the Hot Spare Door of dynamic fault tree, so that the computation is reduced.

Key words: common cause failure, dynamic fault tree, markov chain, reliability analysis, underground railway interlocking system
