| 摘 要： | 根据天文学上的天球模型，选择地平坐标系法的高度角和方位角来描述太阳位置，并将高度角和方位角的算法程序化，以此作为双轴太阳能跟踪装置的核心算法．采用STC89C52作为控制芯片，利用高精度时钟芯片DS12C887提供时间信息，同时引入风速传感器和压力传感器，使得控制系统能在恶劣条件下可实现自保护和除雪自清洁的功能．最后通过立杆投影法验证太阳能跟踪装置的跟踪效果．

| Abstract: | Elevation angle and azimuth angle in astronomy was used to described the sun position, and the elevation angle and azimuth were programmed, which was the core algorithm in biaxial solar tracking system. The IC STC89C.52 was used as the control chip, and the real time was provided by the high-preclslon time IC called DS12C887. Meanwhile wind speed sensor was applied to realize the function of self-protection. Finally the tracking performance was verified by pole projection method. |
