By adopting the technical scheme, when a worker on a scaffold pushes a spraying gun to a high position through a handheld rod to perform coating spraying work, at the moment, the spraying gun is basically in the range of the upward visual angle of the worker, under the condition of strong outdoor light, the putty layer on the wall surface has certain light reflectivity, the roughness degree of the surface of the putty layer is inconvenient to directly observe through naked eyes, when the spraying gun is moved through the handheld rod by the hand, a first roughness probe on a spraying protective cover firstly performs roughness detection on the surface of the putty layer to be sprayed, under the normal condition, the spraying gun is in a normal spraying state, the roughness range of the surface of the putty layer to be sprayed is generally set in a central processing module of a control system to be 50-100 mu m, the roughness range of the surface of the putty layer after coating spraying is 35-75 mu m, namely, a roughness parameter detected by the first roughness probe is set in the central processing module to be 50-100 mu m, a roughness parameter detected by a second roughness probe is set to be 35-75 mu m, when the worker controls the spraying gun to move, the first signal receiving module receives a roughness signal detected by the first roughness probe, and transmits the roughness value of the surface of the putty layer to be sprayed in the normal spraying gun, and if the roughness value of the spraying gun in the normal spraying gun in the normal spraying condition that the roughness range of the surface of the putty layer to be sprayed is set to be 50-100 mu m;
if the first roughness probe detects that the roughness value of the surface of the putty layer to be sprayed is more than 100 mu m, the roughness of the surface of the putty layer at the moment is higher, at the moment, the central processing module sends a command for increasing the spraying amount of the coating to the execution module, the execution module controls the electromagnetic valve to increase the opening amount of the valve, and the spraying amount of the coating sprayed by the atomizing nozzle in unit time is increased, so that the spraying amount of the coating in the rough area of the putty layer is increased, the rough area is quickly filled and leveled up, and the smoothness is ensured, after the single spraying is finished, a second roughness probe behind the spraying protective cover carries out roughness detection on the surface of the putty layer after the coating is sprayed, a second signal receiving module receives a roughness signal detected by a second roughness probe and transmits the roughness signal to the central processing module, and when the second roughness probe detects that the roughness value of the surface of the putty layer after the coating is sprayed is within the range of 35-75 mu m, after the solenoid valve increases the spraying amount, the area with higher putty layer roughness is filled with the coating and the spraying is qualified, if the value of the roughness of the surface of the putty layer after the second roughness probe detects that the spraying of the coating is larger than 75 micrometers, the first spraying is not enough in thickness, and the second spraying needs to be carried out, at the moment, the central processing module sends a voice reminding instruction to the voice broadcasting module, the voice broadcasting module sends voice broadcasting of 'please spray again' to workers, and after the workers receive the voice broadcasting, the spraying gun carries out the second spraying on the front spraying area (normally, the single spraying stroke of the workers is generally 1-1.5 meters, and the second spraying is along the last spraying track and stroke), during the second spraying, the first roughness probe can also carry out the roughness detection on the coating surface which is sprayed for the first time, if the roughness detected by the first roughness probe is qualified (the roughness range is 50-100 mu m), the electromagnetic valve is still in a normal spraying state, if the roughness detected by the first roughness probe is unqualified (the roughness is more than 100 mu m), the spraying amount is increased by the electromagnetic valve, after the second spraying is finished, the roughness of the surface of the putty layer sprayed with the coating is detected by the second roughness probe again, after the roughness is detected to be qualified (the roughness range is 35-75 mu m), the voice broadcasting module sends voice broadcasting 'please continue construction' to the worker, and after the worker receives the voice broadcasting in the next step, the next putty layer area can be sprayed and constructed.
In addition, a distance detector is arranged on the end face of the port of the spraying protective cover, in the actual spraying process, the distance control between the port of the spraying protective cover and the putty layer is very important, when the distance between the port of the spraying protective cover and the putty layer is too small, the spraying protective cover is easy to touch the surface of the putty layer, particularly, when the spraying protective cover is sprayed for the second time, the spraying protective cover is easy to touch the sprayed paint, so that a pit appears on a paint layer, when the distance between the port of the spraying protective cover and the putty layer is too large, the adsorbability of the paint on the surface of the putty layer can be influenced, therefore, the effective construction distance between the port of the spraying protective cover and the putty layer is set to be 5-10cm by the central processing module, when a worker is in construction, the distance detector detects the distance between the port of the spraying protective cover and the putty layer in real time, and the third signal receiving module receives the detection signal of the distance detector and feeds the detection signal back to the central processing module in real time, if the effective construction distance between the port of the spraying protective cover and the putty layer is less than 5cm, the central processing module sends out voice broadcast of 'too close spraying distance' to workers through the voice broadcast module, if the effective construction distance between the port of the spraying protective cover and the putty layer is more than 10cm, the central processing module sends out voice broadcast of 'too far spraying distance' to workers through the voice broadcast module, the voice broadcast can remind the workers to control the effective spraying construction distance in time and ensure better construction effect, under normal conditions, when experienced workers are in construction, the better effective construction distance can be ensured, because the structure is a handheld spraying structure, the distance between the spraying gun and the palm of the workers is far, because of the visual angle limitation of people and the limitation of control flexibility, the distance between the spraying gun and the wall surface is not very well controlled, the distance detector can solve the problem well.

When a worker on a scaffold pushes a spraying gun to a high place through a handheld rod 2 to spray paint, at the moment, the spraying gun is basically positioned in the upward visual angle range of the worker, under the condition of strong outdoor light, a wall surface putty layer has certain light reflectivity, the roughness of the surface of the putty layer is inconvenient to be directly observed through naked eyes, when the worker moves the spraying gun through the handheld rod 2, a first roughness probe 31 on a spraying protective cover 3 firstly detects the roughness of the surface of the putty layer to be sprayed, under the normal condition, the spraying gun is in a normal spraying state, a central processing module 46 of a control system generally sets the roughness range of the surface of the putty layer to be sprayed to be 50-100 mu m, and the roughness range of the surface of the putty layer after the paint is sprayed to be 35-75 mu m, that is, in the central processing module 46, the roughness parameter detected by the first roughness probe 31 is set to be 50-100 μm, the roughness parameter detected by the second roughness probe 32 is set to be 35-75 μm, when a worker controls the movement of the spray gun, the first signal receiving module 41 receives the roughness signal detected by the first roughness probe 31 and transmits the roughness signal to the central processing module 46, if the value of the roughness of the surface of the putty layer to be sprayed, which is detected by the first roughness probe 31, is within the range of 50-100 μm, in this case, the central processing module 46 defaults that the roughness of the surface of the putty layer belongs to the normal range, and the atomizing nozzle 12 of the spray gun is in the normal paint spraying state;
if the first roughness probe 31 detects that the roughness value of the surface of the putty layer to be sprayed is greater than 100 microns, the roughness of the surface of the putty layer at the moment is higher, at the moment, the central processing module 46 sends an instruction for increasing the spraying amount of the coating to the execution module 44, the execution module 44 controls the electromagnetic valve 141 to increase the opening amount of the valve, the amount of the coating sprayed by the atomizing nozzle 12 in unit time is increased, so that the coating spraying amount of the rough area of the putty layer is increased, the rough area is quickly filled and leveled, the smoothness is ensured, after the single spraying is completed, in the moving process of the spraying protective cover 3, the second roughness probe 32 behind the spraying protective cover 3 detects the roughness of the surface of the putty layer after the coating is sprayed, the second signal receiving module 42 receives the roughness signal detected by the second roughness probe 32 and transmits the roughness signal to the central processing module 46, when the second roughness probe 32 detects that the roughness value of the surface of the putty layer after being sprayed with the coating is within the range of 35-75 μm, it indicates that after the spraying amount of the electromagnetic valve 141 is increased, the area with higher roughness of the putty layer is filled with the coating and the spraying is qualified, if the roughness value of the surface of the putty layer after being sprayed with the coating is detected by the second roughness probe 32 to be greater than 75 μm, it indicates that the thickness of the coating sprayed for the first time is not enough, and the coating sprayed for the second time needs to be sprayed, at this time, the central processing module 46 sends a voice prompt instruction to the voice broadcast module 45, the voice broadcast module 45 sends a voice broadcast of "please spray again" to the worker, and after receiving the voice broadcast, the worker sprays the area sprayed in front for the second time by using the spraying gun (normally, the stroke of a single spraying of the worker is generally 1-1.5 m, and the second spraying is performed along the spraying track and stroke of the last time), in the process of the second spraying, the first roughness probe 31 can also detect the roughness of the surface of the paint sprayed for the first time, if the roughness detected by the first roughness probe 31 is qualified (the roughness range is 50-100 μm), the electromagnetic valve 141 is still in a normal spraying state, if the roughness detected by the first roughness probe 31 is unqualified (the roughness is more than 100 μm), the electromagnetic valve 141 increases the spraying amount, after the second spraying is completed, the second roughness probe 32 detects the roughness of the surface of the putty layer sprayed with the paint again, after the roughness is qualified (the roughness range is 35-75 μm), the voice broadcasting module 45 sends voice broadcasting 'please continue the next construction' to the worker, and after the worker receives the voice broadcasting, the next putty layer area can be sprayed and constructed.
In addition, the end face of the port of the spraying protection cover 3 is provided with a distance detector 33, the distance control between the port of the spraying protection cover 3 and the putty layer is very important in the actual spraying process, when the distance between the port of the spraying protection cover 3 and the putty layer is too small, the spraying protection cover 3 is easy to touch the surface of the putty layer, particularly, when the spraying is carried out for the second time, the spraying protection cover 3 is easy to touch the sprayed paint, so that a paint layer has pits, and when the distance between the port of the spraying protection cover 3 and the putty layer is too large, the adsorbability of the paint on the surface of the putty layer can be influenced, therefore, the central processing module 46 sets the effective construction distance between the port of the spraying protection cover 3 and the putty layer to be 5-10cm, and when a worker is in construction, the distance detector 33 carries out real-time detection on the distance between the port of the spraying protection cover and the putty layer, the third signal receiving module 43 receives the detection signal from the distance detector 33 and feeds back the detection signal to the central processing module 46 in real time, if the effective construction distance between the port of the spraying protection cover 3 and the putty layer is less than 5cm, the central processing module 46 sends a voice broadcast of "too close spraying distance" to the worker through the voice broadcast module 45, if the effective construction distance between the port of the spraying protection cover 3 and the putty layer is more than 10cm, the central processing module 46 sends a voice broadcast of "too far spraying distance" to the worker through the voice broadcast module 45, the voice broadcast can prompt the worker to control the effective spraying construction distance in time and ensure better construction effect, and in normal situation, when the worker is experienced in construction, the better effective construction distance can be ensured, because the structure is a handheld spraying structure, the spraying gun has a farther distance to the palm of the worker, because of the visual angle limitation of people and the limitation of control flexibility, the distance between the spray gun and the wall surface is not well controlled and the distance detector 33 can better solve the problem.
