复杂装备的层次诊断技术

首先从完备性的角度分析了对复杂装备进行层次诊断的可行性,论述了层次诊断模型应具备的组成内容.然后通过面向对象的知识表示方法建立了装备层次模型,通过对Petri网的分层细化建立了故障层次模型.最后,通过知识库的方式将装备层次模型和故障层次模型进行关联实现,并给出了相应的层次诊断策略.

The Research of Hierarchy Diagnosis Technique of Complicated Equipment

First,this paper analyzes the feasibility of hierarchy diagnosis to complicated equipment from the point of view of completeness,and discuss the content of the hierarchy diagnosis model must be comprised.Then,we build up the equipment hierarchy model with the object-oriented method,and build up the fault hierarchy model by hierarchical refine Petri net.Finally,this paper gives the associate realization of equipment hierarchy model and fault hierarchy model with knowledge database,and propose the strategy of hierarchy diagnosis.
