摘　　要：本文描述了一种基于单片机控制的太阳能自动追踪装置,包括太阳能电池板、直流电动机、驱动器、控制单元、光敏半导体、光电检测追踪模块和视日运动轨迹追踪模块。该装置吸收了光电检测追踪模式和视日运动轨迹追踪模式这两者的长处,晴天时采用光电检测追踪模式,利用光敏二极管的A/D转换电路来判断太阳位置,配合步进电机控制太阳能电池板对阳光进行即时追踪;阴雨天时进入视日运动轨迹追踪模式,通过软件计算当时太阳的方位角和高度角来进行追踪。可以对直流电机转速和转动方向进行精确的控制,实现电机的启动、正转、反转等操作。This paper introduces a device of solar automatic tracking based on MCU＇s controlling, including solar panels, DC motor, driver and controller, which connecting with photosensitive semiconductor, photoelectric detection and tracking module and tracking trajectory module. The device benefits from both advantages of two modules, using photoelectric detection and tracking module as sunny, judging the sun＇s position with A/D conversion circuit of photosensitive diode and controlling solar panels with the stepper motor to track the sunshine; using tracking trajectory module as cloudy, calculating the angle of the position and height of the sun at that time through software to track. It can control precisely the rotational speed and direction of DC motor to achieve operation of start, rotating clockwise or counter clockwise of motor
