舰船装备电子电路故障区域节点跟踪定位方法梅杰，高峰(湖北工业大学工程技术学院，湖北武汉430068)摘要:为提升故障区域节点跟踪定位效果，为舰船安全航行提供保障，研究舰船装备电子电路故障区域节点跟踪定位方法。通过最小二乘支持向量机，延拓处理不同状态下舰船装备电子电路的原始数据；利用经验模态分解算法，在延拓处理后的数据内，提取不同状态下电子电路故障特征；通过在马氏距离内引入权值，得到改进马氏距离算法；采用改进马氏距离算法，计算提取故障特征与已知故障集间的马氏距离，依据马氏距离完成故障区域节点跟踪定位。实验证明：该方法可有效提取不同状态下，舰船装备电子电路故障特征；该方法可有效跟踪定位电子电路故障区域节点，且跟踪定位精度较高。关键词：舰船装备；电子电路；故障区域节点；跟踪定位；支持向量机；马氏距离中图分类号：TM131文献标识码：A文章编号：1672–7649(2023)12–0152–04doi：10.3404/j.issn.1672–7619.2023.12.030TrackingandlocatingmethodofelectroniccircuitfaultareanodeinshipequipmentMEIJie,GAOFeng(HubeiUniversityofTechnologyEngineeringandTechnologyCollege,Wuhan430068,China)Abstract:Thispaperstudiesthefaultareanodetrackingandlocatingmethodofshipequipmentelectroniccircuit,im-provesthetrackingandlocatingeffectoffaultareanode,andprovidesguaranteeforshipsafenavigation.Theleastsquaressupportvectormachineisusedtoprocesstheoriginaldataoftheelectroniccircuitsofshipequipmentindifferentstates.Theempiricalmodedecompositionalgorithmisusedtoextractthefaultcharacteristicsofelectroniccircuitsindifferentstatesfromthedataafterextendedprocessing.ByintroducingweightsintheMahalanobisdistance,animprovedMahalanobisdis-tancealgorithmisobtained.TheimprovedMahalanobisdistancealgorithmisusedtocalculateandextracttheMahalanobisdistancebetweenthefaultfeatureandtheknownfaultset.Experimentalresultsshowthattheproposedmethodcaneffect-ivelyextractthefaultcharacteristicsofshipequipmentelectroniccircuitsunderdifferentstates.Thismethodcantrackandlocatethefaultareanodeofelectroniccircuiteffectively,andthetrackingandpositioningaccuracyishigh.Keywords:ship'sequipment；electroniccircuit；faultareanode；trackingandpositioning...
