Abstract: Belt conveyor is an important equipment of coal transport. In this paper, through the analysis of the mechanical analysis of the adhesive tape transport system, the factors that affect the power of the belt conveyor are obtained. According to the characteristics of nonlinear, time-varying belt conveyor, belt conveyor simulation device by using fuzzy -PID control system design theory of belt conveyor, according to the filling rate of coal, realize the speed regulation of conveyor belt, and real-time monitoring by PC software FactoryTalk View. The results show that the system can adjust the belt speed of the belt conveyor according to the filling rate of coal, and the energy-saving effect is obvious.
