Mine water curtain dust fall climate online monitoring linkage system

The utility model discloses a mine water curtain dust fall climate on-line monitoring linkage system which comprises water curtain spray pipes connected with a water vapor input header pipe, the water curtain spray pipes are arranged on an underground coal face, an air inlet way and an air return way respectively, and water vapor sprayed out of the water curtain spray pipes forms a coal face water curtain, an air inlet way water curtain and an air return way water curtain. A dust concentration sensor, a temperature sensor and a humidity sensor are distributed on a coal face, and a central controller is connected with the dust concentration sensor, the temperature sensor and the humidity sensor on a well through interfaces. The output control of the central controller is respectively connected with a first control valve, a second control valve, a third control valve and a fourth control valve, the first control valve controls a first water curtain spray pipe of an air inlet way, the second control valve contro
