【Abstract】 This paper analyzes the fault diagnosis system classification and representation, diagnostic inference stratgy, parsimonious set covering model and its improvement. After discussing the method of constructing fault diagnosis system and frame representation,a way for constructing fault diagnosis system of 40kVA UPS system is presented, and a knowledge based simple diagnosis system has been built.更多还原
