Abstract
In order to quickly and accurately realize the automatic tracking of sunlight,a design scheme of point-light source automatic tracking system based on single chip microcomputer is presented in this paper. The MSP430 chip is used as a micro con?troller and USES LM317 to design a light source with adjustable brightness,light intensity is detected by using light activated tri?ode,combined with the relevant algorithm of computing control software to drive two stepper motor to control the laser pointer from top to bottom and move around,so that the laser pointer can quickly and accurately find the position of the light source.Through the point light source brightness control of tracking experiment,the results show that the whole system can realize preferably to point light source tracking within the scope and is of adaptability.关键词
