Mine automatic sprinkler device adopts good performance as the controller, powerful, simple circuit, reliable work and high cost performance. Colleagues have network communication function and upgrade the ordinary spray controller.
3路输入，控制2路电动球阀，可在最多6个工作模式下选择工作： The controller can be connected with 3 external inputs to control 2 electric ball valves, and can choose to work in up to 6 working modes:
1.1 Alley frequent spray mode;
1.2 Alley working timing spray mode;
1.3 Reproduction point spray mode;
1.4 arson spray mode;
1.5 Removable spray mode;
1.6 Mining random hydropower spray mode.
Through the above rich working modes, it can adapt to a variety of application scenarios, so as to achieve the dust removal effect.
CO含量正常时（ 小于 24*10-6ppm），气路电动球阀打开，气钻可以工作；当 CO含量超标时，能及时切断气路电动球阀，打开水路电动球阀，喷水进行灭火；只有当主动关闭急停开关后，才停止喷水，否则CO含量下降到正常水平后，依旧喷水。 It can accurately execute the control signal from the ground substation, and can monitor the CO content in real time to quickly determine whether a control signal is generated . When the CO content is normal ( less than 24 * 10-6ppm), the electric ball valve of the gas circuit is opened, and the gas drill can work ; When the content exceeds the standard, the electric ball valve of the gas circuit can be cut off in time, the electric ball valve of the water circuit is opened, and water is sprayed to extinguish the fire; only when the emergency stop switch is actively closed, the water spray is stopped, otherwise the water content is still sprayed after the CO content drops to a normal level. Multiple sensors can be installed for signal acquisition.
