Abstract: Aiming at the problems of low efficiency,poor operational reliability,relatively high personnel labor intensity and others in the semi-automation monitoring way of the central water pump room,in order to further improve the operational efficiency and reliability of the coal mine drainage system and promote the improvement of the management level of the downhole central water pump room,through research on computer control and automation monitoring technology,a downhole central water pump room automation monitoring scheme based on PLC control and intelligent sensing fusion detection network is proposed.The corresponding software and hardware systems are designed,and the system adopts PLC as the control core.Multiple intelligent sensors are adopted to conduct real-time collection of core operating parameters such as the liquid level of the water tank,the flow rate of the water pump press and so on in the central water pump room.The remote real-time monitoring,data analysis management,fault alarm and other functions of the ground dispatch center are realized through communication network transmission,and remote automation monitoring of the central water pump room is achieved.Through practical testing,the system can achieve unattened of the central water pump room,effectively improving the operational efficiency of the pump room equipments and providing reliable guarantees for the safe and stable operation of the pump room.
