FMS系统中的实时故障监测与系统评价

Real Time Fault Monitoring and System Evaluating in FMS

该文对ＦＭＳ系统中的实时故障监测与系统评价进行研究。在考察静态故障树组成结构和运行环境及ＦＭＳ的运行特征的基础之上，提出了ＦＭＳ的一般实时故障树模型及其面向对象的知识表示与推理方法。该方法综合运用故障树技术、面向对象的节点描述及存贮和正、反向推理策略，达到了迅速、准确检测故障的要求。文末给出该系统的组成结构和实现方法，通过实际系统的试验运行，证明了该方法的有效性。

The method of real time fault monitoring and system evaluating has been studied. Based on the research of structure and operation environment of static fault tree as well as the operational characteristics of FMS, a generalmethod of FMS real time fault tree m odelas well as its object-oriented know ledge representation and reasoning have been presented. This method, synthetically utilizing the fault tree technique, object-oriented node description and storage techniques as well as forward and backward reasoning strategies, performed the fast and accurate fault detection. Finally, the architecture and implementation method of the system have been provided. The result of experimental operation shows that the method is effective.
