Research on Speed Control of Scraper Conveyor Based on Load Prediction

针对综采工作面刮板输送机存在的轻载、超载问题,进行负载预测下的刮板输送机调速控制系统设计,同时基于模糊PID控制模型对采煤机与刮板输送机牵引速度进行协同调节。通过试验发现,该系统能够有效降低刮板输送机轻载、超载运行时长,并可进行带速的自适应调控,达到节能减耗效果。

In order to solve the problems of unbalanced power distribution of the first and last motors,failure of the inverter motor and damage of the scraper chain under the operation of the scraper conveyor in complex working conditions,a permanent magnet inverter-driven scraper conveyor central control system based on the three-in-one power coordination control system,condition monitoring system and upper computer monitoring system is designed,and the working principle of each system is given to improve the smoothness and safety of the operation of the scraper conveyor and to provide a certain guarantee for the mine The working principle of each system is given to improve the smoothness and safety of scraper conveyor operation and provide certain guarantee for eficient and safe mining.
