Abstract

The invention provides a correcting method and device for top coal caving control and electronic equipment. The method comprises the steps of obtaining a theoretical value and a current actual measurement value of a top coal caving operation parameter when a top coal caving support executes a current top coal caving operation; based on the theoretical value and the current actual measurement value, correcting the theoretical value by using a pre-trained PID control model to obtain a corrected theoretical value of the top coal caving operation parameter; and executing the next top coal caving operation based on the correction theoretical value. According to the method, in an actual top coal caving process, the top coal caving support can carry out top coal caving according to the theoretical value of the top coal caving operation parameter, that is, the top coal caving support can really reach the ideal top coal caving operation parameter (namely reach the theoretical value of the top coal caving operation parameter), the precision is high, the top coal caving accuracy and the top coal caving efficiency are improved, the technical problems of poor top coal caving accuracy and low efficiency caused by poor precision of an existing top coal caving control method are relieved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a correction method, device and electronic equipment for top coal caving control. Background technique [0002] At present, the method of fully mechanized coal mining is to manually open the gate to discharge coal, and to judge indirectly whether the coal discharge is completed by observing the amount of coal inclusions during the coal discharge process with human eyes. When the amount of gangue inclusion reaches a certain level, the gate is closed to stop coal discharge. Complete a coal discharge process with a single ram. However, with the continuous improvement of the intelligent level of coal mining, the manual fully mechanized coal mining operation is being replaced by intelligent control technology. The measurement of coal seam parameters through image, distance sensor, radar and other equipment can often realize the control of top coal caving operation parameter...
