Machine shutdown control method and device, electronic equipment and storage medium

The invention discloses a machine shutdown control method and device, electronic equipment and a storage medium. The method comprises the steps that current signal data and current images of all protection devices are collected; for each protection device, performing feature extraction on the current image of the protection device to obtain a current image feature matrix of the protection device; loading a standard image feature matrix of the protection device from the image feature library; randomly generating a plurality of current new feature matrixes in a feature value space corresponding to the protection device, and screening out a current center feature matrix, wherein the deviation between the current center feature matrix and the standard image feature matrix is smaller than a preset threshold value; extracting a center vector with the minimum deviation from the current image feature matrix of the protection device from the current center feature matrix to form an output vector of the protection devi
