The system is mainly used for online monitoring of coal mine dust concentration of different dust places, and according to the position automatic sprinkler control dust concentration monitor to action. The dust concentration of dust concentration sensor, underground substation into frequency signal into parallel, and then through the signal line has been transmitted to the monitoring host ground current, by the industrial TV directly display the location of dust concentration sensor. Dust concentration once detected over a limited set of values (such as 50mg/m3), the system will automatically open the electromagnetic valve, the air of dust sprinkler on the position; but the dust degree is lower than the set limit, automatically closes the electromagnetic valve, stop spray.The system is mainly used for online monitoring of coal mine dust concentration of different dust places, and according to the position automatic sprinkler control dust concentration monitor to action.
