OPC has been widely applied to coal mine automation control system as an industry standard of communication between the field control substation and PC in the control system. In this paper, through the analysis and design for the transport system of coal mine belt conveyor, communication between the PC and S7-300 PLC is realized by using OPC technology. This paper gives the configuration scheme of OPC Server and develops the OPC Client program. The actual operation shows that the system is stable, reliable of communication and high of data real-time.

This paper constructs a coal-conveying control system based on programmable logic controller (PLC), which is applied to the residual heat and pressure integrated energy-saving technological transformation projects, and realizes the performance of security, reliable and efficient operation. This control system consists of the PLC control system, computer control system and industrial television monitoring system. After more than one year of actual operation shows that the system structure is reasonable, reliable operation, at the same time, reduce labor intensity, improve the utilization rate of equipment, the stable operation also provides a practical reference for other similar projects.
