摘　　要：为了使太阳光始终垂直太阳能电池板照射,提高太阳能转化为电能的效率,设计了以STM32F103ZET6为核心,外围扩展光强采集,步进电机,GPS,液晶显示等的自动跟踪系统。LCD液晶显示屏显示相关数据,太阳光跟踪采集模块采用视日运动轨迹追踪与光电检测两种方式相互配合,GPS模块获取当地的时间日期及经纬度等信息,据此测算太阳方位角及高度角,并驱动步进电机调整太阳能板角度。测试表明系统能实现实时跟踪太阳光,工作稳定,灵活性强。In order to make the sun vertically irradiate the solar panel, improving the efficiency of solar energy into electricity. This system uses STM32F103ZET6 as the core control chip, system expands the light intensity acquisition, stepper motor, GPS, LCD display etc. LCD screen displays related data, sunlight tracking acqui- sition module depends on the trajectory tracking following the sun and photoelectric detecting to complement each other. The GPS module is used to obtain the local time, date, latitude and longitude information, ac- cording these estimates solar azimuth and elevation angle, then drives the stepper motor to adjust the angle of the solar panels. The test shows that the system can achieve real-time tracking the sun, work stability and flexibility.
