Method and system for adjusting natural light guide cylinder capable of automatically compensating brightness, and medium

The invention provides a method, a medium and a system for adjusting a natural light guide tube capable of automatically compensating brightness, and belongs to the technical field of architectural lighting. The method comprises the following steps: acquiring initial brightness values of different indoor positions through a plurality of brightness sensors arranged indoors; obtaining preset indoor standard brightness and a standard brightness value obtained by each brightness sensor under the standard brightness condition; the output brightness of the light guide cylinder and the brightness of the indoor lamp are adjusted, so that the current brightness value obtained by each sensor is matched with the standard brightness value of the corresponding sensor; indoor brightness is adjusted according to data detected by a brightness sensor, so that a light guide cylinder and a lamp in a large building are coordinated, and the brightness in the large building can be kept stable; through the arrangement, the problem
