The Research And Application Of Water Supply System In Heidaigou Coal Mine

It is subjected to shenhua hadai ditch coal mine on the basis of the actual production conditions, the application of water supply system. Water supply system is mainly divided into three parts:central monitoring station, pump room intelligent equipment and information acquisition device. Central monitoring station is based on the Windows operating system according to the production requirements of the using king view software development monitoring and control system, the function of the complete data real-time remote monitoring; Pump room intelligent equipment using PLC to realize automatic constant pressure water supply control, PLC controller with the GSM module to realize the data acquisition of the wireless receiving and control water pump control command of wireless data transmission; Data acquisition devices using sensors to pool water level, water supply pipeline and equipment parameters acquisition and the acquisition of information sent to the pump room control, data acquisition terminal with PLC as the controller, sensor and GSM module connected to the controller to realize data acquisition and wireless transmission function. Center monitor and pump room intelligent devices through GPRS wireless network data connection.Water supply system of water is provided by the groundwater after a triple pressure, so the water supply system of site design since the fourth. The system is made up of four pressure station and five pressure station of two sites. Five pool water levels fall, PLC through GSM network will water level signal station to no.4, no.4 stop PLC according to the received signal, the pipe pressure signals and the output of the inverter PID arithmetic, sent the inverter control signal to control motor speed,4 class stand up automatic intelligent constant pressure water supply, keep five pool water level within the set value of 18 m. Level 4 station and five station with natural elevation difference to supply water to the water at around. Tested, stable operation, the system of wireless communication, five standing pool water can keep around the set value.
