Research on Communication Method for the Coal Mine Drainage Control System

The communication method of the automatically drainage monitoring system for underground coal mine is researched. The advanced PLC control technology and visual InTouch human-machine interface are used to design the control system. The information which is measured by downhole monitoring device can be real-timely transmitted to the ground monitoring stations through the Ethernet optical fiber communication system. The monitoring system can realize on-site manual and automatic control, also can realize remote monitoring and management. This paper mainly describes the implementation process and implementation principle of the data transfer between control unit and remote host computer via Ethernet technology.
