基于Markov模型的分布式监测系统可靠性研究

STUDY ON MARKOV MODEL BASED RELIABILITY FOR DISTRIBUTED MONITORING SYSTEM

监测系统作为一种保证复杂系统正常工作与提高其运行可靠性的重要手段被广泛应用。监测可靠度指监测系统能成功地对被控对象进行监测的概率,它是评价监测系统性能的一个重要尺度。以可靠性理论为指导,结合集中分布式监测系统的结构特性,对该类型监测系统的监测可靠性进行深入研究,提出一种基于Markov模型的监测可靠性分析方法。随后,以捏合机监测系统为例进行验证与分析。分析表明该方法对监测系统设计及其维护有一定的应用价值。

As an important means of improving the reliability of complex systems and ensuring that they can function better, distributed monitoring systems are usually designed and used in many areas. A centralized distributed monitoring system, which is usually used in monitoring system design, is presented. Based on reliability theory and the characteristics of this type of systems, monitoring reliability defined as the probability of successfully measuring and monitoring the object which is under control, an important performance measure for the distributed monitoring systems, is investigated. Furthermore, a case of application is used to illustrate the procedure. Analysis results show that the method proposed here is practical and valuable for designing monitoring systems and their maintenance.
