Design and Implementation of Automatic Drainage in Coal Mine
Drainage system is one of the important sub-systems of coal mine integrative control platform, and is used to guarantee the safety of mining and auxiliary transportation under the ground. The functions of drainage system are defined, the network framework is designed, the start and stop procedures of the pump engine under the manual control mode and automatic control mode are described, and the determining methods based on liquid level to control several pumps in automatic mode are analyzed. By using Simense PLC module, power source module, digital module, analog module and touch screen hardware, the drainage system control platform is set up, which is connected to the control computer on the ground by using Simense communication module and industrial ring Ethernet, and achieved the purpose of remote control.
