【Abstract】 This paper presents a fault diagnosing intelligent petri net for pumping stations. When the fuzzy behavior petri net is used in an earlier fault diagnosis system, the credibility of rulers is treated as a fixed constant. To use it for a pumping station with changing work state, an intelligent deducing method to calculate the credibility of core rules was developed, which described and deduced information using Pr/T PN. The definition of fault diagnosing intelligent petri net and an example of engine overloading of axial pump were described detailed to explain the model and diagnosis method with fault diagnosing intelligent petri net.更多还原
