摘要
文章以某温湿度监控系统为研究对象,对其进行系统可靠性建模和评估。先从组成系统各部件的硬件角度入手,对系统各功能模块可靠性数据的收集和预计;然后将系统所处的环境因素和实际工作参数变换为相应的环境因子,对各模块进行可靠性数据的修正;最后采用故障树分析法(FTA)对系统进行可靠性建模和仿真。
This paper researches a temperature-humidity supervising and controlling system and makes the system reliability model. The reliability data of the components of system are collected and calculated, and then the actual environment and working conditions are transformed into environmental factors and the reliability data are modified, by using fault tree analytical method, the system reliability model is set up and simulation for the model is carried through.
