摘要
以综合监控系统为研究对象,在对地铁综合监控系统整体架构进行研究的基础上,将系统看作一个离散的异步动态系统,对系统主要设备的控制部分建立可靠性数学模型。运用Lyapunov函数的分析方法证明模型的可靠性,依据控制网络可靠性理论对综合监控系统的平均无故障时间及平均故障修复时间两个指标进行计算,验证系统在不同程度失效时的可靠性。
To study the Integrated Supervisory & Control System( ISCS),a reliability mathematical model is established for the control of the main equipment of the system,which is regarded as a discrete asynchronous dynamic system based on the study of the overall architecture of ISCS. The reliability of the model is proved with the analysis of Lyapunov function,and the mean fault-free time and mean fault recovery time of the comprehensive monitoring system are calculated based on the control theory of network reliability,and the reliability of the system in different degree of failure is verified.
