摘　　要：以往应用系统故障诊断模糊行为 PETRI网中规则的可信度为固定常数 ,由于泵站工作状况在改变 ,因此 ,应用在泵站系统时 ,提出了以谓词变迁网 (Pr/ T- PN )存储知识 ,智能推理计算重要规则可信度的方法 ,并给出了明确的定义。以轴流泵出现动力机过载情况为例 ,说明了泵站系统故障诊断智能 PETRI网的构造和诊断方法。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.
