为了解决故障诊断中的冲突消解问题 ,将故障概率信息和管理信息引入模糊 Petri网 ,提出故障诊断综合信息网模型。研究了基于综合信息网的故障诊断问题 ,对故障进行分类 ,分析了不同类型的故障诊断所需管理信息的内容 ,确立了概率与管理信息的关系 ,通过机械手掉刀故障的诊断 ,验证了该模型和方法的正确性与可行性 In order to solve the problem of conflict resolution in fault diagnosis, the fault probability information and management information are introduced into fuzzy Petri net to propose fault diagnosis integrated information network model. The problems of fault diagnosis based on comprehensive information network are studied, the faults are classified, the contents of the management information needed for different types of fault diagnosis are analyzed, the relationship between probability and management information is established, and the diagnosis of the fault Correctness and feasibility of models and methods
