基于模糊Petri网的某型舰炮系统故障诊断

故障的产生和传播是一个动态的过程,具有突发性、并发性和随机性等特点,精确的推理方法难以有效地对复杂特性的故障进行诊断.利用模糊Petri网对舰炮武器系统进行故障分析,首先分析舰炮故障类型以及故障的规则表示形式,然后给出了基于模糊Petri网的故障传播模式模型及其推理算法,最后以某舰炮武器系的弹药盘点异常故障为例进行了建模并用推理算法计算故障发生概率.结果表明,该模型具有直观和表达能力强的优点,可应用于工程实践.

Fault Diagnosis in A Naval Gun Based on Fuzzy Petri-Net

The occurrence and propagation of fault is a dynamic process.It’s unexpected,concurrency and stochastic.A precise fault diagnosis model is hard to handle the complicated characteristics of system faulty.This paper proposes the fuzzy Petri-Net applying in the fault diagnosis of the naval gun system.First it analyse the fault category of naval gun and the expression rules of fault;then explain the model of fault propagation based on fuzzy Petri-Net and its reasoning algorithm;at last apply this model to a real fault diagnosis of naval gun system and calculate the probability of falte with the reasoning algorithm.The result proved that this model is intuitive and articulat,the reasoning algorithm is effective and valueble.
