摘要
为了更充分、高效地利用太阳能的热量,设计了以TMS320F2812为控制核心的太阳能双轴跟踪控制系统。该系统采用视日运动轨迹和传感器校正混合跟踪方案。首先DSP根据相关的理论公式和参数计算出白天太阳的高度角和方位角,并将其转化成相应的脉冲来控制步进电机进行一级跟踪,然后光电传感器检测实际太阳的位置,输出偏差信号来驱动步进电机进行二级校正跟踪,从而获得最大的太阳能热量。理论分析表明,采用该跟踪技术可以有效地提高能量接收率。
In order to fully utilize solar energy with high efllciency, this paper designs dual-axis solar tracking control system which is based on TMS320F2812.By adopting sun motion trajectory tracking and sensor calibration hybrid tracking strategy. First, the sun altitude angle and azimuth angle in daytime are calculated by related theory formulas and parameters using DSP, which are converted to the corresponding primary tracking pulse to control the step motor and photoelectric sensor to detect the actual position of the sun, the output error signal will drive the stepper motor tracking adjustment for the secondary, so as to achieve maximum solar heat. Theoretical analysis shows that using the tracking technology can effectively improve the energy receiving rate.
