The Design of Sunlight Collecting Machine in the Fiber Optic Lighting System

Abstract:

As the sunlight must illuminate the optical fiber in a certain angle in the fiber optic lighting system, a sunlight collecting machine is designed. It uses the 3DU51 light activated triode to transform the changes of sunlight's intensity which is caused by the position of the sun into electrical signals. And after the processing of ADC0809 converter, the signal is sended to AT89S51 single-chip microcomputer which will produce electrical signals to control the electromagnetic relay switches closed or disconnected, realizing that the driving motor can be controlled to start rotating and stop rotating automatically. So the sunlight collecting machine can track the position of the sun, collecting the most strong direct sunlight, improving the system's efficiency of collecting sunlight.
