摘要
为了提高太阳能电池板的工作效率,设计了一种基于ARM920T平台的太阳能电池板自动追光系统。系统以ARM920T内核S3C2440处理器为控制器,根据二维光位置敏感探测器PSD的电流输出量确定电池板绕竖直轴和水平轴转动的方向和角度,进而由2个步进电机驱动双轴跟踪系统,以达到自动追光的目的。经测试表明,该系统运行稳定、可靠,具有良好的应用前景。
An automatic solar panel light-tracking system based on ARM9 platform was designed to improve the efficiency of solar panels.S3C2440 was used as the controller of the system.Based on the current outputs of the 2D positional sensitive detector（PSD）,the directions and angels at which the horizontal and vertical axes should rotated,respectively,were calculated.Two step motors were used to control the two-axis system to trace sun position automatically.Running test shows that the system is stable and reliable,and it has good application prospect.
