摘要
为了高效利用太阳能,为太阳能板加装追光系统是一个简单可靠的实现方式。基于北斗授时定位的太阳能追光系统由嵌入式芯片S3C2440与北斗模块通讯获取太阳能板所在位置和当前时间,再通过太阳定位算法实时计算出太阳方位角与高度角,最终由步进电动机驱动器来驱动双轴电动机调整太阳能电池板,以最大角度接收太阳能,实现追光。实验证明,基于北斗授时定位的太阳能追光系统可替代基于GPS的追光系统,且更具优势。
To use the solar energy more efficiently,a solar tracking system installed on a solar panel is a simple and reliable solution. A solar energy tracking system based on Beidou works as follows. An embedded chip S3C2440 communicates with Beidou to get the position and time of the solar panel. A realtime positioning algorithm is executed to calculate the azimuth and elevation angles of the sun. A stepper motor drives the double axis motors to adjust the solar panel to receive maximum solar energy. Experiments show that the solar tracking system based on Beidou is superior to the GPS-based technique.
