Description

technical field

[0001] The invention relates to the technical field of automatic control, in particular to a compressed air automatic spraying device and system. Background technique

[0002] For the special working environment of coal mine underground, the construction progress is often affected due to the large amount of dust, so the spray device which plays the role of dust prevention is indispensable. At present, there are multiple spraying devices underground in coal mines, and multiple spraying devices can form a spraying system. However, since each spraying device needs to be manually opened and closed, and there are a large number of spraying devices, if all of them are manually operated, it will take a lot of time. manpower and time.

[0003] In the prior art, the automatic spraying device can effectively save manpower and time, but since the automatic spraying device mostly relies on the electric control or sound control system, when the electric control or sound ...
