In the related art, when the concentration of the underground dust fog is high, the light penetration of the movable lighting device 1 and the fixed lighting device 2 is poor, so that the underground visibility is reduced, and the underground safe production is not facilitated. In order to solve the problem, in the application, the cloud server 5 can intelligently adjust the color temperatures of the corresponding mobile lighting device 1 and the corresponding fixed lighting device 2 according to the dust fog concentration of the lighting area, and different dust fog concentrations can correspond to the color temperatures of the different mobile lighting device 1 and the different fixed lighting device 2, so that the color temperatures of the mobile lighting device 1 and the fixed lighting device 2 can meet the lighting requirements under the current dust fog concentration, and the underground visibility can be improved, and the underground safe production can be guaranteed. For example, when the concentration of the dust fog is low, the requirement for the penetrating power of the light is low, and the color temperature of the mobile lighting device 1 and the fixed lighting device 2 can be increased, and when the concentration of the dust fog is high, the requirement for the penetrating power of the light is high, and the color temperature of the mobile lighting device 1 and the fixed lighting device 2 can be reduced.

For example, when the light intensity is high, the brightness of the mobile lighting device 1 may be reduced to prolong the effective working time of the mobile lighting device 1, whereas when the light intensity is low, the brightness of the mobile lighting device 1 may be increased to ensure that the brightness of the mobile lighting device 1 meets the lighting requirement under the current light intensity.
In summary, in the intelligent mine lighting system provided by the embodiment of the invention, the cloud server can intelligently adjust the color temperatures of the corresponding movable lighting device and the fixed lighting device according to the dust fog concentration of the lighting area, so as to ensure that the color temperatures of the movable lighting device and the fixed lighting device meet the lighting requirements under the current dust fog concentration, and the intelligent mine lighting system is beneficial to improving the underground visibility and ensuring the underground safe production.

In order to solve the problem, in the application, the cloud server 5 can adjust the color rendering index of the fixed lighting device 2 in the lighting area according to the light intensity and the dust fog concentration of the lighting area, so as to ensure that the color rendering index of the fixed lighting device 2 meets the image acquisition requirement under the current light intensity and the dust fog concentration, the image quality acquired by the camera 6 or the inspection robot 7 is improved, the image identification difficulty is reduced, and the intelligent requirement of a mine is met.

At this time, the illumination brightness of the mobile illumination device 1 can be reduced at the same time to save energy consumption.
Meanwhile, the cloud server 5 may adjust the brightness of the fixed lighting device 2 in the lighting area where the underground person or the inspection robot 7 does not exist to a second brightness level, so as to reduce the brightness of the fixed lighting device 2 in the lighting area where the underground person or the inspection robot 7 does not exist, thereby saving energy consumption.
Optionally, the cloud server 5 may adjust the color temperature and the color rendering index of the mobile lighting device 1 and the fixed lighting device 2 according to an optical three-primary-color red, green, and blue (RGB) additive synthesis principle.
