摘要
针对铁路信号中常用的双机热备结构进行了可靠性和安全性分析。通过把单元的失效率划分为一些独立的部分 ,根据各部分失效率对系统的影响 ,利用马尔可夫模型可以同时分析可靠性和安全性性能。本文比较了两种不同工作方式双机热备结构的可靠性和安全性性能 ,并给出了结论和建议。
This paper analyzes the reliability and safety of dual module hot spare architecture which is widely used in railway signalling system to achieve high reliability and safety. The failure rates are divided into several different parts, and the reliability and safety may be analyzed by using Markov model according to the effects of each part of the failure rate. The reliability and safety of two different modes of dual module hot spare architecture are analyzed and compared in this paper. Conclusion and advice are also given finally.
