摘要
为了提高太阳能的利用率,更加高效地开发太阳能资源,提出了软件计算与传感器实时检测太阳光强相结合的控制方法。根据当地的时间、经纬度,得到当天太阳的高度角和方位角,驱动电机跟踪太阳位置;然后通过实时中断检测太阳光强,控制电机在一定的小范围内调整太阳光板,精确地跟踪太阳光强的最大点,提高了太阳光的利用率。主要介绍了控制系统组成、硬件电路设计以及实时跟踪软件的设计。
In order to improve the utilization of solar energy and develop solar energy resources more efficiently, a control method of the software algorithms combined with sunlight intensity real-time detection by sensor was proposed. By calculating the local time, latitude and longitude, the pitch angle and horizontal angle of the sun could be gotten, and the motor was driven to track the sun posi- tion. Then, by real-time interrupt to detect the sunlight intensity, in a certain small range, the solar panels were adjusted by controlled motor. The strongest signal of sun was tracked accurately, and the utilization of solar energy was greatly improved. The system compo- nents, designs of hardware circuit and real-time tracking software were introduced mainly.
