摘要
根据云架构综合监控系统的软件硬件架构,结合系统特点,建造了云架构综合监控系统的故障树图,并进行了定性分析,找出影响系统可靠性最大的底事件,利用分析结果指导综合监控系统的实施,提高了系统的可靠性。另对云架构综合监控系统和传统综合监控系统的可靠性作了计算和对比,论证了云架构综合监控系统的可靠性满足城市轨道交通建设运营要求。
According to the software and hardware architectures of ISCS based on cloud architecture, and combined with the characteristics of the system,a fault tree diagram of ISCS on the cloud architecture is constructed. Through qualitative analysis,the bottom event is detected which has the greatest impact on the reliability of the system,and the analysis result is used to guide the implementation of ISCS and improve the reliability of the system. In addition,the reliability of ISCS based on cloud architecture and the traditional ISCS are calculated and compared,it shows that the reliability of ISCS based on cloud architecture could meet the requirements of urban rail transit construction and operation.
