自动故障隔离

Automatic Testing and Fault Isolation can make the MTTR of system be reduced, or enhance the availability of system.

通过自动检测和隔离故障，使系统或设备的平均维修时间显著减小，提高系统的可用性；同时减少维修人员的数量、降低对维修人员技术水平的要求，进而降低使用及保障费用。

This intormation is combined in the structure of a Bayesian Graph so as to identify unknown or unpredictable faults. The final experiment results show the intelligent agent can detect network abnormal behavior before a fault actually occurs. Event correlation algorithm for network fault real-time isolation and handle uses object-oriented model method for critical network device and a novel coding scheme, even if in the case of lost alarm and wrong one, it also can identify the fault origin and automatically adapts to changes to network topology to ensure seemless scalability to large and complex network environment. Its performance greatly presides over traditional rule-based event management system.

对学习获得的信息经由贝叶斯图加以组合，从而签别未知的或不可预见的故障，实验结果表明智能监测代理系统能够在故障发生以前检测网络异常行为；用于网络故障问题实时隔离和处理的事件关联算法使用面向对象的针对的网络关键设备的建模方法和新型编码技术，即使在丢失报警和错误报警的情况下，亦能精确地标识故障源，并能自动适应网络拓扑的改变，从而保证无缝地伸缩到专用大型和复杂网络环境中，其性能大大优于传统的基于规则识别的事件关联系统。

This paper introduces the research arm of automatism check and measure and isolation and give an alarm system, to confirm the technology project, to solve the linchpin technology, and go deep into research and experiment to actualize automatism check and measure and isolation and give an alarm to electromagnetism valve with malfunction from theory and technology.
