Background
The explosion-proof water shed is a facility widely used in the underground coal mine for isolating coal dust gas explosion shock waves and flames, and has important significance for the safe production of the coal mine. The water shed is composed of water bags which are erected on the top of the roadway and filled with water, when coal dust or gas explodes, the water bags are shaken over and broken by shock waves, water is sprayed by waterfalls, water mist zones are formed, and the whole roadway is filled with the water mist zones. The water bag can buffer the shock wave strength in the process of turning over by earthquake, so that the damage to the top plate is reduced; the water mist can effectively reduce the concentration of suspended coal dust, prevent the ground coal dust from being raised due to shock waves, absorb heat and suffocate fire, so as to inhibit and prevent the propagation of explosion and control the explosion in a certain area; the explosion-proof water shed can reduce the explosion intensity and harm.
Because the water quantity in the explosion-proof water bag is influenced by dynamic evaporation, the water quantity is reduced every moment, and the explosion-proof water bag is required to be always in a full state by technical and safety management regulations. In order to ensure the safe production of the coal mine, a specially-assigned person is required to regularly replenish water for the explosion-proof water bag.

In addition, in the water replenishing process, an operator is arranged below the water bag, so that the water replenishing quantity cannot be accurately controlled, so that the water overflows or the water quantity after water replenishing is still lower than the standard water quantity, and related potential safety hazards are brought.
Therefore, the wireless intelligent water replenishing system for the mine is provided.
