摘　　要：提出一种基于加权模糊Petri网(weighted fuzzy petri net,WFPN)的1553B总线网络故障诊断方法;在探讨加权模糊Petri网形式化定义和加权模糊产生式规则形式的基础上,给出了基于矩阵运算的加权模糊Petri网推理算法;以某1553B总线网络为例,建立了其故障诊断的WFPN模型,分析了系统故障原因的可信度,验证了所提方法的有效性;可以为1553B总线网络故障诊断研究提供有益参考。A method of fault diagnosis for 1553B bus network based on weighted fuzzy petri net （WFPN） is proposed. Based on the dis- cussing of the formalize definition of WFPN and the forms of weighted fuzzy production rule, the reasoning algorithm of WFPN based on ma- trix operations is given. A 1553B bus network is used as an example, and the model of fault diagnosis is constructed. The confidence of fault causes are analyzed, and the proposed method is validated. This paper can provide theoretical basis for related research on fault diagnosis for 1553B bus network.
