Electroencephalogram signal identification method and device, medium and equipment

The invention discloses an electroencephalogram signal recognition method and device, a medium and equipment, and relates to the technical field of electroencephalogram signal recognition. The method comprises the steps that electroencephalogram time sequences of multiple channels are collected through electrodes located at different brain region positions, so that electroencephalogram signals to be recognized are obtained; constructing a recognition model comprising a brain function network acquisition layer, a spatial-temporal feature extraction layer and an output layer; inputting a to-be-recognized electroencephalogram signal into the constructed recognition model, and adaptively constructing a brain function network topological graph by a brain function network construction layer through learning a relation between channels; the spatial-temporal feature extraction layer extracts time features and spatial features of a brain network in a staggered manner by using a time convolution layer and an image conv
