基于模糊数学理论的煤矿机电设备故障诊断分析

Fault Diagnosis of Coal Mine Electromechanical Device Based on Fuzzy Mathematic Theory

为了对煤矿机电系统进行故障诊断,以寸草塔煤矿为研究背景,采用模糊数学法对该煤矿机电设备的运行状况和故障状况进行了权重系数和归一化系数计算。研究结果表明:该煤矿机电系统总体症状归一化系数和总体故障归一化系数均小于0.5,且该煤矿机电系统具有较好的合理性和安全性。

In order to diagnose the fault of electromechanical devices, the method of fuzzy mathematic was used,taking the Cuncaota Coal as engineering background, the weight coefficient and normalization coefficient of running state and fault status of electromechanical system were calculated. The results show that both of the weight coefficient and normalization coefficient of electromechanical system are less than 0.5. Also, the safety and rationality of electromechanical system of Cuncaota coal is very good.
