摘要
利用故障树分析方法,对靶场某系统的监控单元结构进行可靠性分析和可靠性建模仿真计算,查找出监控单元在结构方面存在的薄弱环节,并对其结构进行改进,改进措施为采用分布式结构和主备切换方式,最后对改进后的系统进行可靠性分析。
In the paper,the structure of a monitoring unit which equipment in a transponder device is analyzed by means of fault tree,and built the reliability model to simulation,to found the weak link of the system＇s structure.Then to improve the reliability of the system,main use the distributed structure and activestandby switch to improve the reliability.Finally analysis the reliability of the improved system.
