Abstract: Coal in the coal yard under the action of the wind make the coal dust into the air caused by the pollution of the environment, the common method is to use the manual method of high pressure water gun to the coal at regular time that can not only prevent the coal dust from flying, but also can prevent the spontaneous ignition of the coal in the low burning point under the condition of high temperature in summer. Intelligent sprinkler system based on environmental monitoring which based on wireless sensor network is put forward in this paper. The environmental monitoring timely according to the changes of the main factors, such as wind, temperature and so on, to decide the sprinkler system whether open or and the yield of water .The system uses Stacked Autoencoder and fuzzy forecast to forecast situations . The results show that the effect of dust removal is improved and the water consumption is reduced. The utilization rate of water resources was improved, the dust control efficiency reached 90%, and the utilization rate of water resources was up to 86%.
