The invention discloses an under-grate pressure prediction method in a cement cooling process based on information fusion. The under-grate pressure prediction method comprises the following steps: S1,determining a feature vector of information fusion; S2, processing the field production data to determine reasonable production data; S3, selecting a scoring model; and S4, determining a multi-modelfusion neural network structure, and predicting the under-grate pressure in the cement cooling process. The invention provides an under-grate pressure prediction method in a cement cooling process based on information fusion. According to the prediction method combining feature fusion and model fusion, the feature fusion can improve the quality of modeling data and ensure the stability of model establishment, and the model fusion can comprehensively consider the prediction precision of various basic prediction methods under different production data and different conditions to ensure the stability of prediction results.
