Real-time monitoring device for working spraying surface of spray gun and control method of real-time monitoring device

The invention relates to the technical field of spraying robots, in particular to a real-time monitoring device for a working spraying face of a spraying gun and a control method thereof, and the control device comprises a spraying area laser display module used for displaying a preset spraying area of the spraying gun through laser; the spray gun inclination angle measuring module is used for detecting the inclination angle of the spray gun; the spraying distance measuring module is used for detecting the distance between the spraying gun and the working surface; and the spraying control module is connected with the spraying area laser display module, the spray gun inclination measuring module and the spraying distance measuring module and used for judging whether the preset spraying area corresponds to an area to be sprayed or not, and if yes, the spraying pressure of the spray gun is obtained according to the inclination angle and the distance. According to the technical scheme, the accuracy of spraying te
