Temperature control method and system for 3D glass hot bending mold

The invention discloses a 3D glass hot bending mold temperature control method and system, and the method comprises the steps: obtaining a temperature rise curve of each temperature measurement point of a 3D glass hot bending mold, carrying out the segmentation and segmentation discrete control, obtaining the theoretical temperature SUi (tn) of the ith temperature measurement point at the future moment in a time region [tm, tn], and detecting the instantaneous temperature VUi (t); establishing an LSTM prediction model, and inputting the plurality of instantaneous feature vectors into the trained LSTM prediction model to obtain a predicted temperature WUi (tn) of the ith temperature measurement point at a future moment in the time region [tm, tn]; calculating the difference between the theoretical temperature SUi (tn) and the instantaneous temperature VUi (t) to obtain an instantaneous temperature difference value, and calculating a main control quantity corresponding to the ith temperature measurement point b
