The utility model relates to a linkage control device based on raise dust monitoring system, including the raise dust monitor that is arranged in monitoring air PM numerical value, raise dust monitorcommunication connection has the coordinated control case, the coordinated control incasement is equipped with the coordinated control ware, is used for to control the relay and the ac contactor of dust fall equipment, linkage controller is connected with the relay, the ac contactor and the control switch of dust fall equipment are connected, the relay is connected with ac contactor and the relaycontrols opening and cutting out of dust fall equipment through opening and shutting of control ac contactor, the coordinated control case is equipped with the air switch who is used for controlling the power of coordinated control case, air switch is connected with the surge protector who is used for protection control mainboard. This linkage control device based on raise dust monitoring system realizes the operating condition of automatic control dust fall equipment, and labour saving and time saving avoids the resource of wasting water, and the real -time high efficiency of dust suppressioneffect.
