Aiming at the problems existing in the structure and constant speed operation control of SGZ 1250/2400 scraper conveyor in 5308 coal mining face,a scraper conveyor operation control system based on load prediction was built.Sensors were set to obtain the information of sprocket meshing frequency,and a predictive model was constructed by convolutional neural network to realize load prediction.Based on the load prediction results,fuzzy PID can be used to adjust the transport scheduling of the scraper conveyor to reduce energy consumption and wear points.After the field application,the constructed scraper conveyor control system ran smoothly,the load prediction results were accurate,the adjustment precision of fuzzy PID was high,the stability of fuzzy PID was strong,and the energy consumption and wear amount of the scraper conveyor were reduced by about 15%and 10%respectively compared with before the application,so the application benefits were significant.
