Switch cabinet busbar temperature rise early warning method and system based on error sequence correction

The invention discloses a switch cabinet busbar temperature rise early warning method and system based on error sequence correction, and the method comprises the steps: inputting a temperature rise time sequence data set into a preset LSTM temperature rise prediction model, and carrying out the subtraction of a pre-value of each output prediction time step length and an actual observation value, and obtaining a temperature rise prediction error value; taking the temperature rise prediction error value, a prediction result corresponding to the temperature rise prediction error value and an actual result as an input sequence of a preset temperature rise error prediction model to obtain an error correction value output by the temperature rise error prediction model; taking the error correction value and the prediction result as a final temperature rise target prediction value; searching a target parameter combination with the minimum error sum of squares between the temperature rise target predicted value and th
