摘要
针对弹载1553B总线网络故障诊断建模中动态故障行为的模糊特性较难描述的问题,提出一种基于模糊Petri网(fuzzy petri net,FPN)的弹载1553B总线系统故障诊断模型,并给出了基于矩阵运算的推理算法;以某型弹载1553B总线系统为例,分析了系统故障原因的可信度;分析表明:所建模型可以实现系统故障的快速诊断,大大减少了诊断时间,提高了诊断的准确度。
In 1553B bus network in missile it is hard to describe the fuzzy characteristics of dynamic fault behaviors. Therefore, a new fault diagnosis model of 1553B bus system in missile by fuzzy petri net （FPN） is proposed and the reasoning algorithm based on matrix operations is given. The confidences of fault reason are analyzed in a type of 1553B bus system in missile. The analysis shows that the proposed model can achieve fault diagnosis rapidly and accurately.
