Central Pumping Station automatic drainage system is one of the important systems that make coal industry automatic in production, and its development and application has great prospects. However, most of domestic coal mine drainage systems are still using the traditional relay control. Water level monitoring, pump switch and the choice of switching are all artificially pleted. With its operation plex, reliability low, and the labor of workers intensive, this system has seriously affected the management of underground drainage system and the economic benefits of coal industry. In this paper, the underground drainage system is based on PLC control technology, and it adopts a programmable controller, which replaces the traditional relay control. At the same time, it bined with configuration software, which realized the automatic drainage system for remote monitoring and control. This system uses Mitsubishi PLC (Model FX2N64MR) as the central controller, and expands the necessary analog input module (FX2N4AD) and munication module. Through program control, the system has automatic and manual control mode, so you can freely switch. In automatic mode, according to the dynamic changes of water level by monitoring, the System is optimized to start the pump, which achieves system coordination. The pumps and pipe of the system adopts work system by rotation, so every time you start, you always open the pumps and pipe of minimum running time. With fault monitoring and protection, the system can accept the remote PC monitoring and control, which can plete the fault tips and emergency alarm. This makes up the traditional coal mine drainage system, improves security and reliability, and plays a significant role in promoting the mine industrial automation.
