Engine fault data real-time generation method based on fault feature migration

The invention discloses an engine fault data real-time generation method based on fault feature migration, and the method comprises the steps: determining the fault feature parameters of an engine, collecting the fault feature data of a data source engine and the fault-free feature data of a known object engine, and constructing a fault feature data set I and a fault-free feature data set Ib; solving similar data centers in the fault feature data set I to obtain fault style representative data, and constructing a fault style data set If according to the fault style representative data; training the VGG16-Mini classification network by using the fault-free data set Ib and the fault style data set If so as to output a fault feature data set Ig based on fault feature migration; and according to the fault feature parameters, collecting fault-free feature data of the to-be-detected object engine, constructing a fault-free feature data set Ib ', and inputting the fault-free feature data set Ib' into the trained VGG
