Identification method and device for opening and closing identification instruments of transformer substation and storage medium

The invention discloses an identification method and device for opening and closing identification instruments of a transformer substation and a storage medium. The method comprises the steps of collecting image data of an opening and closing identification instrument as a training sample; wherein the image data comprises an image training set and an image test set; inputting the image test set into a preset image recognition model to obtain a plurality of candidate frames and categories of each division and combination identifier in the image test set; wherein each candidate box corresponds to one category score; and selecting an optimal candidate box of the opening and closing identifier from the plurality of candidate boxes, and determining the optimal candidate box as a final detectionbox of the opening and closing identifier. According to the method, by constructing the image recognition model, the working state of the opening and closing identification instrument can be effectively and accurately recogn
