摘　　要：提出了一种基于OSPF路由协议思想的虚拟维修诱导技术方法VMIT。首先列出OSPF核心部分与VMIT的对应关系,然后阐述VMIT的基本内涵,包括编制零件或总成层级码,通过零件发出故障信号以诊断故障零件,利用小波神经网络预测维修时间,采取改进的Dijkstra算法求解和评价更换零件最优路径。最后以更换离合器油封为例,阐述虚拟维修的四个阶段,分别为给油封及周边零件编制层级码,根据故障信号查找故障零件,利用小波神经网络预测拆装油封及周边零件的时间,获取拆除油封的最优路径。案例的四个阶段与VMIT的四个基本内涵相呼应,同时也进一步证明了VMIT的可行性。A virtual maintenance guidance technology method VMIT based on the idea of OSPF routing protocol is proposed.First,the corresponding relationship between OSPF core parts and VMIT is listed,and then the basic connotation of VMIT is stated,including programming parts or assembly level codes,sending fault signals through parts to diagnose faulty parts,using wavelet neural network to predict repair time,and adopting improved Dijkstra algorithm to solve and evaluate the optimal path of replacement parts.Finally,taking the replacement of the clutch oil seal as an example,the four stages of virtual maintenance are explained.They are to compile hierarchical codes for the oil seal and surrounding parts,find the faulty parts according to the fault source,and use wavelet neural network to predict the removal time to install the oil seal and surrounding parts,therefore to get the best solution to remove the oil seal.The four stages of the case correspond to the four basic connotations of VMIT,which proves the feasibility of VMIT.
