Design and Implementation of Knowledge Base for Fault Diagnosis Expert System of Loader Hydraulic System

According to the trouble feature of loader hydraulic system,by using relevant theory of expert system and data structure and object-oriented design approach,the design and implementation of knowledge base for fault diagnosis expert system of loader hydraulic system are discussed on the basis of fault tree of diagnosis knowledge.The hierarchical multi-base structure,the fault tree based knowledge representation of production rule and object-oriented approaches are adopted in the knowledge base.Thus it can improve the efficiency of the fault diagnosis and provide a scientific and effective method for the design of knowledge base of fault diagnosis expert system.
