Design of Belt Transmission Control System Based on PLC
Abstract Belt conveyor is widely used as a material transfer equipment, part of it is simple, and can transport large amounts of material at a time, and adapted to long-distance transmission, safe and reliable operation of the system as a whole. These characteristics make it become the most important coal mining unit of transport equipment. Large and super large coal mines in China are growing with the development of science and technology, and business functional requirements for belt conveyor is also increasing. Belt conveyor for its various advantages, have become a main transportation tool in the coal mining industry [5]. In the course of belt conveyor running, due to various reasons will appear portrait tear, vibration and misalignment common failure, once the above failure occurs, the consequences are often severe, this paper analyzes the reasons for the failures and influence, while around failure analysis solution, choose the corresponding sensors and the monitoring and protection of the system.
Full text of a detailed statement of the overall design of the system. Control unit to PLC controller, combined with the distributed control system DCS, as well as sensors, achieving fault detection and classification of belt conveyor starts and stops.
Belt conveyor based on PLC systems, belt transmission system to improve efficiency and productivity, and production costs and losses due to failure greatly reduced, which makes it valuable.
The paper Figure 18, table 2, 26 references are presented.
