摘要传统的太阳跟踪方式多是基于光电检测技术或者是与天文学相关的太阳运动轨迹的技术,存在着跟踪精度低、成本高昂等缺点。为了提高太阳能跟踪系统的精度，并减小相应跟踪误差, 提高利用太阳能的效率,本文设计了一种以STC12C5A60S2单片机为控制核心的双轴伺服跟踪控制系统,采用光强控制和时空控制互补的方式。在跟踪策略上,晴天光照强度达到设定值时采用光强控制,光照强度低于设定值时采用时空控制跟踪, 实现了全方位、全天候、高精度的实时跟踪。经过多次试验,该太阳能跟踪系统工作性能稳定,实现了对太阳的实时精确跟踪。81686

Title    The Research Of Solar Tracking System                 

Abstract The traditional way of sun tracking is based on the photoelectric detection technology or the solar motion trajectory technology related to astronomy, which have many shortcomings such as low tracking accuracy、high cost。 In order to improve the accuracy of the solar tracking system, and reduce the corresponding tracking error and improve the efficiency of solar energy utilization, this paper designed a biaxial tracking servo control system using microcontroller core with STC125A60S2 single chip microcomputer, and it takes Light intensity control combined with space time control as tracking method 。When it comes to tracking strategy, on sunny day when the light intensity reaches the set standard ,the system chooses the light intensity control ,otherwise the system will use the space-time tracking control。 In this way, it manages to achieve a comprehensive, all-weather, high-precision and real-time tracking。 Experimental results show that the stability of the control system performance is good, which means it achieves real-time precise tracking of the sun successfully。
