摘要针对计算机联锁系统的二乘二取二容错结构,基于马尔可夫模型,将各单元的失效率划分为几个独立的分量,根据每部分失效率对结构的影响,利用计算机对系统的可靠性和安全性进行分析和仿真计算。结果表明,二乘二取二容错结构满足铁路联锁系统高可靠性和高安全性要求。 It was analyzed the architecture of double 2-vote-2 Computer-based Interlocking System by using Markov model. The failure rates were divided into several different parts. The reliability and safety could be analyzed according to the effects of each part of the failure rate by using computer. The result showed that the double 2-vote-2 fault-tolerant architecture satisfied requirements of high reliability and safety in Computer-based Interlocking System.
