摘要:

针对如何分析功能安全产品的可靠性问题,提出了一种基于Markov模型的可靠性分析方法。通过对产品的系统结构进行分析,研究系统的 Markov状态转移图,结合失效模式、影响及其诊断分析(FMEDA)法对系统进行可靠性建模,引入状态转移矩阵,并以功能安全温度变送器为例对模型进行验证。相关验证结果表明,该模型应用于功能安全领域是可行的。

Abstract:

A reliability analysis method based on the Markov model is proposed for analyzing the reliability of functional safety products.Based on the analysis of the structure of the product and study of the Markov state transition diagram of the system,the system reliability modeling is performed by the failure modes effects and diagnostic analysis method (FMEDA),with the state transition matrix   introduced.The model has been verified with the functional safety temperature transmitter as an example.Results show that application of the Markov model in the field of functional safety is feasible.

Key words: temperature transmitter;functional safety;reliability;Markov model;FMEDA
