ABSTRACT

With the advent of the information age, the industry is also developing in the direction of automation. The application of PLC and computer communication is more and more extensive. For small and medium-sized belt conveyors, the control system is usually controlled by relays, which has poor reliability, high labor intensity and low production efficiency. Therefore, it is necessary to develop a belt conveyor control device based on PLC. Based on this, the development and the existing problems of centralized control system are analyzed firstly. Then the working principle of PLC is briefly introduced. Next we generalized the structure and electrical requirements of the belt conveyor, and finally elaborated the design of the control system, including the main equipment required, system hardware circuit and software system. We also elaborates on the anti-interference related content. The system shows good operation through debugging and can play its function in practical applications.
