| Abstract: | A diagnosis expert system based on MCD debris is studied, which is applied in the wear condition monitoring and fault diagnosing of aircraft engines. In this paper, the acquisition and representation of diagnosis knowledge are discussed firstly. According to the design idea of the object oriented ES template, an all in one construction strategy of knowledge base, inference engine and user interface is studied, based on which a heuristic inferring mechanism of depth preferred searching with reverse induction and positive control is introduced. |
