Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
See Fig. 1 and Fig. 2, airborne dust monitoring and automatic dustfall system, include data processing unit 1, respectively with data processing
Unit 1（Single-chip microcomputer based on 32 arm processors）The airborne dust monitoring unit 2 of connection, spray control unit 3, LED display 4,
GPRS communication modules 5 and alarm lamp 6；Airborne dust monitoring unit 2 includes PM2.5 particulate matter sensors, PM10 particulate matter sensors
With TSP airborne dust sensors, spray control unit 3 includes the time relay 31, air switch 32, A.C. contactor 33, water pump
34th, the nozzle being connected by spray piping with water pump 34, magnet coil one end of the time relay 31, the time relay 31 it is normal
A tip side for opening contact electrically connects with a phase line end of air switch 32, phase line end, the ac contactor of the motor of water pump 34
The phase line end of device 33 electrically connects with another tip side of the normally opened contact of the time relay 31, the electromagnetism of the time relay 31
The earth terminal of the coil other end, the earth terminal of the motor of water pump 34, the earth terminal of A.C. contactor 33 with air switch 32 is electrically connected
Connect, and another phase line end of air switch 32 is connected with power supply VCC, the digital output modul port of air switch 32, time relay
Device 31 is connected with data processing unit 1.
Operation principle of the present utility model：
