环境自动监控系统可靠性的分析与仿真研究

Reliability Analysis and Simulation of Environment Detecting and Controlling System

利用故障树分析法,对某环境自动监控系统的可靠性进行仿真分析研究,根据系统所处的环境状态从组成系统的基本部件出发进行可靠性数据的收集和计算,然后运用蒙特卡洛方法对系统进行了基于故障树的仿真建模和运算,并通过分析计算结果得出系统故障分布的模型以及各基本部件的重要度,最后进行了故障分布的参数估计和假设检验。

In the paper, an environment detecting and controlling system is analyzed by means of fault tree, and the reliability data of its basic components are collected and calculated based on the environment condition. Then the system is emulated by using Monte-Carlo method. The system fault distribution, the parameter estimation and the Weightiness of the components and are also given by analyzing the emulating results. At last the parameter estimation of system and the test are completed.
