Single-stage equipment defect identification method and device

The embodiment of the invention provides a single-stage equipment defect identification method and device, and belongs to the technical field of power equipment operation and maintenance. The identification method comprises the following steps: acquiring a to-be-identified equipment picture in a close-shot state; decoloring operation is carried out on the equipment picture; sequentially executing at least three times of first convolution operation on the decolored equipment picture; sequentially executing a second convolution operation and a pooling operation on the equipment picture after executing the first convolution operations for three times; executing a first matrix multiplication operation on the equipment picture subjected to the three times of first convolution operations and the equipment picture subjected to the pooling operation; performing global average pooling operation on the equipment picture after the first matrix multiplication operation; executing a second convolution operation on the dev
