Indoor sunshine bathing system control method and system of time-share spot following

Abstract

The invention belongs to the technical field of optics, and discloses an indoor sunshine bathing system control method and system of time-share spot following. The indoor sunshine bathing system control method comprises the steps that comparison of light intensity is carried out by adopting two photosensitive sensors, a control circuit plate drives a direct current motor according to the magnitudes of the light intensity, control of motor steering is realized, lighting device light-following rotation is driven; the lighting device uses the focusing principle of convex lens for lighting, manufactures a three-dimensional hollow cone by adopting 3D printing technology and determines a focal position, one end of a light guide optical fiber is fixed to the focal position, the other end of the light guide optical fiber is connected to inside, sunshine is introduced into a room, then the light is diverged through a concave lens; and a long-distance relay is controlled by an APP on a mobile phone to perform long-distance control. The comparison of light intensity is carried out by adopting the two photosensitive sensors, and the control of the motor steering is realized by the control circuit so that a light-following rotation function is realized. Focusing, divergency and total reflection transmission of the light are realized through combination of the lens and the light guide optical fiber.
