High-precision steel coil blanking size deviation adjusting method and system and electronic equipment

The invention relates to the technical field of metal plate cutting, in particular to a high-precision steel coil blanking size deviation adjusting method and system and electronic device.The method comprises the steps that sound data, hydraulic pressure data and height data of a hydraulic nut are obtained, and a blanking time period is intercepted; the fixed pressure of each time of blanking is obtained; feature extraction is carried out on the amplitude of the sound data of each time of blanking, and the bright band starting and ending moments of each time of blanking are obtained; based on the difference characteristics of the bright belt starting and ending moments of each blanking and a plurality of previous blanking and the hydraulic pressure data, the fracture slope of the plate in each blanking is obtained; and on the basis of the fixed pressure of current blanking and the fracture slope of the plate, the fixed pressure of next blanking is obtained in combination with a simulated annealing algorithm.
