摘　　要：本文提出在故障诊断的层次化分解基础上,结合模糊Petri网(FPN,Fuzzy Petri Network)实现故障推理过程。首先将层次化的诊断分解模型采用Petri网中变迁和位置的转移来进行描述。推理算法采用矩阵运算,充分利用了Petri网的并行性处理能力,并能够描述故障传递状态。该推理过程简单,并能够使诊断效率得到提高。Based on hierarchical fault diagnosis method, fuzzy petri nets (FPN) is applied for fault reasoning process. At first, hierarchical diagnosis model is described according to fuzzy Petri net place and transition. Matrix based computation method is employed for reasoning process, Petri nets parallel characteristics is adopted and fault transition condition can be described. The proposed method is simple in reasoning process and fault efficiency is improved.
