A method for classifying and early warning of abnormal psychological states in miners

This invention discloses a method for graded early warning of abnormal psychological states in miners. It extracts and filters features from three modal signals processed in the time domain, frequency domain, time-frequency domain, and spatial domain to obtain corresponding first target signal feature sets. Based on optimal transmission theory, the maximum mean difference algorithm, and a selected kernel function, the first target signal feature sets are aligned locally and globally to obtain second target signal feature sets. These second target signal feature sets are then mapped to a unified, preset-dimensional embedding space for comparative learning to obtain a third target signal feature set. The third target signal feature set is then weighted, summed, and input into a bidirectional long short-term memory network to obtain initial fused features. These features are then input into a GhostNet network to obtain fused features, which are then input into the psychological state recognition module of a psychological graded early warning model to determine the miner's psychological state. Finally, these features, combined with mine environment parameters, are input into the early warning grading module of the psychological graded early warning model to obtain early warning information.
