针对矿井提升系统故障中不确定因素,利用灰色关联理论,分析各个因素引发故障的可能性大小,首先将各个因素序列与参考序列进行对比,通过关联系数与关联度计算,最后对关联度排序,说明不确定因素与故障之间的关系,从而为故障中不确定因素诊断的可靠性提供理论依据。
Aiming at the uncertain factors in the failure of mine hoist system, the gray relational theory is used to analyze the possibility of each factor causing fault. First, the sequence of each factor is compared with the reference sequence, and then the correlation coefficient and correlation degree are calculated. Finally, Explain the relationship between uncertainties and failures, and provide a theoretical basis for the reliability of the diagnosis of uncertainties in the failure.
