Referring to fig. 5, when matching based on the powder distribution area and the preset cleaning strength, it includes:
step S500: judging whether the powder distribution area is larger than a preset illumination influence area.
The illumination influence area is the area when powder is distributed in an illumination area to influence the illumination brightness, and means that the powder characteristic shields the illumination of a larger illumination area, so that the illumination brightness of the illumination device is weakened. It is thus possible to know whether the powder affects the normal illumination of the illumination device by comparing the powder distribution area with the illumination influence area.
Step S501: if the air blowing speed is smaller than or equal to the preset air blowing speed, a standby prompt is sent out to prompt the preset air blowing cleaning device to keep standby.
If the powder distribution area is smaller than or equal to the illumination influence area, the falling amount of the coating powder is smaller, normal illumination of the illumination device is not influenced at the moment, cleaning is not needed immediately, and the blowing cleaning device is instructed to keep standby.
Step S502: if the dust distribution area is larger than the preset powder collection groove position, analysis is carried out according to the dust distribution area and the preset powder collection groove position, and the position close to the powder collection groove is determined.
If the powder distribution area is larger than the illumination influence area, the coating powder falling amount is larger, and the normal illumination of the illuminating device is influenced, so that the analysis accuracy of the light transmission intensity value is influenced, and the falling coating powder needs to be cleaned. Before cleaning, the position adjacent to the powder collecting tank is searched, wherein at least two dust collecting tanks are arranged at the position, and the two dust collecting tanks are symmetrically arranged relative to the lighting device and are respectively arranged at two edges of the lighting device. Because the radium carving pattern carries out radium carving in-process, carries out the position difference of radium carving, consequently the position that the dust dropped also is different, so the regional position that the dust distribution area corresponds also has the difference with the distance between the different powder collecting vat. By comparing the distance between the region corresponding to the dust distribution area and the two dust collection tanks, the dust collection tank position closest to the region can be known, and the position is defined as the position adjacent to the dust collection tank so as to facilitate subsequent calling.
Step S503: analysis is performed based on the proximity of the powder collection trough to determine the orientation of the blow and to issue a cleaning match cue.
And (3) connecting the positions of the adjacent powder collecting tanks as target directions, defining the directions of the connecting directions to the adjacent powder collecting tanks as blowing directions, and sending a cleaning matching prompt after determining the blowing directions.
Step S504: based on the cleaning strength matching prompt, the blowing cleaning strength corresponding to the powder distribution area is matched.

Step S601: and analyzing according to the blowing direction and the blowing cleaning devices to determine the starting sequence of the blowing cleaning devices.

For example, the furthest blowing purge device is defined as number 1, the next-level blowing purge device is defined as number 2, and so on, until the ordering is complete.
Step S602: the plurality of blowing cleaning devices are instructed to blow in sequence based on the start-up sequence and the matched blowing cleaning intensity.
After determining the starting sequence and the blowing cleaning intensity, the blowing cleaning devices are instructed to sequentially perform blowing cleaning with the blowing cleaning intensity according to the starting sequence, so that dust can be effectively blown into the dust collecting tank closest to the dust collecting tank.
Step S603: timing after the blowing cleaning device is started to determine the starting time.
After each blowing cleaning device is started, timing is carried out through the starting time of the corresponding blowing cleaning device, and the timing time is defined as starting time length so as to facilitate subsequent further calling.
Step S604: when the starting time length is consistent with the preset effective time length, the blowing cleaning device is instructed to stop blowing, and a detection prompt is sent out.
Step S605: and acquiring the luminous area image again based on the detection prompt for analysis so as to determine whether the blowing cleaning device is instructed to perform blowing cleaning or keep standby.
The effective duration is a duration value preset by a worker, and whether the time of the blowing cleaning device when blowing cleaning reaches the duration set by the worker can be known by comparing the starting duration with the effective duration, wherein the effective duration can be 2 seconds, 3 seconds or other times, and the blowing cleaning device can enable dust falling from laser carving to be effectively blown away from an illumination area of the illumination device in the continuous blowing process of a period of time. When the starting time length is equal to the effective time length, the blowing cleaning devices are instructed to stop, so that the blowing cleaning devices stop blowing in sequence, and the blowing cleaning devices cannot occupy too much energy consumption.
And when the blowing cleaning devices stop blowing, sending out detection prompts to instruct the cameras to acquire the light-emitting area images again, analyzing the powder distribution areas corresponding to the powder characteristics in the light-emitting area images, and executing the methods recorded in the steps S502 to S505 again when the powder distribution areas are larger than the illumination influence areas so as to clean the dropped powder in a blowing manner.

Through establishing a flue gas concentration matching database in advance, energy values corresponding to different laser marking energies are stored in the flue gas concentration matching database, and the laser marking energies which can generate corresponding flue gas concentrations are stored, so that when the laser marking energies are input, the corresponding flue gas concentration values can be searched and output.
