Remote Control System of Mine Gas Pumping Station

Remote Control System of Mine Gas Pumping Station

■ Overview
Mine gas drainage monitoring system is used to monitor the parameters of gas drainage pipelines, gas drainage pump parameters, water supply, and power supply parameters in gas drainage, and calculate the standard condition mixed quantity and standard condition pure quantity of gas drainage, and give the day, month, and Annual analysis report, and control each node equipment according to the process and emergency treatment process, to achieve automatic control of gas, pumps, water pumps, pump room fans, cooling towers, exhaust fans, pipeline electric valves and lighting; the system consists of It consists of monitoring host, substation and power box, display control cabinet, explosion-proof PLC control box, pipeline parameter sensor, environmental parameter sensor and water supply parameter sensor. To Inoue, The gas flow, temperature, pressure, methane concentration, carbon monoxide concentration, etc. in the downdraining pipeline are continuously monitored, and converted into the mixed gas flow and pure flow under standard conditions, and the cumulative discharge volume is calculated.
