摘要
在舰炮武器系统的故障诊断中,由于系统的复杂性和直接监测的困难,应用故障机理分析方法判断征兆故障成因间的关系极为困难。介绍了应用模糊数学进行的故障诊断方法,充分利用故障统计数据和专家经验,根据隶属度与贴近度函数来判断征兆群与故障成因之间的关系,从而实现当输入系统征兆后计算机对系统状况的自动诊断。
In fault diagnosis of naval gun weapon system, it is very hard to estimate the relationship of the causes of symptom faults because of the system＇s complexity and the difficulty of direct measure. A kind of fault diagnosis method is introduced which adopts fuzzy mathematic theory and it makes full use of fault statistic data and erpert experiments, estimates the relationgship between symptom groups and fault causes and realizes auto diagnosis with computer to system＇s situation after symptom input.
