摘要
为了最大限度的利用太阳能,采用自动跟踪太阳的方式以获得更多的能量。简要介绍了现有的几种主要跟踪方式,光电探测器跟踪方式容易受天气条件干扰,时钟跟踪方式有累积误差或者因数据库庞大导致反应变慢等缺点。提出了一种时钟跟踪与光电探测器跟踪相结合的双轴跟踪方式,方位角采用时钟跟踪,俯仰角采用四象限光电探测器跟踪,控制核心选用ATmega16单片机。该跟踪方式结合这两种跟踪方式的优点,很好地克服了两者的缺点。实验表明,本系统转动精度高,工作稳定性好,太阳能接收损失小。
A sun-tracking system has been developed in order to receive more solar energy. The opto-electronic-tracking mode is likely to be perplexed by weather condition; the time-tracking mode can not avoid the cumulative error or the slow reaction which caused by a big database or complicated calculations. A new two-axes automatic tracking mode which combines clock-tracking and opto-electronic-tracking is presented. Time-tracking mode is designed for the tracking of Azimuth while opto-electronic-tracking is designed for the tracking of Pitching. The control core is an ATmega16 SCM. The new combined mode overcomes the shortcomings of the two modes. Experiments show that this system works with high precision, good stability and little loss of solar energy.
