摘  要:
为提高太阳能的利用率,以AT89S52单片机为控制核心,采取极轴式跟踪方式,设计了一套以视日运动轨迹跟踪为主、光电跟踪进行跟踪校正的智能型双精度太阳跟踪系统,该系统通过采集时钟芯片信息计算当前太阳位置,实现视日运动轨迹跟踪;同时利用光电传感器采集的光强偏差控制步进电机,实现光电跟踪,校正轨迹偏差,保证聚光板与太阳光相垂直。试验表明,该太阳跟踪系统能在不同天气状况下对太阳进行较准确跟踪,能量接收效率提高20%以上,达到了充分利用太阳能的目的。

摘  要:
In order to improve the operating factor of solar energy,an intelligent double-precision automatic tracking system of sun was designed.AT89S52 singlechip was used as the control core,and polar tracking mode was adopted.The sun trajectory tracking was used as main mode,with photoelectric tracking used for regulating.The system calculates the present position of sun by collecting information from clock chip,to achieve trajectory tracking;while the photoelectric sensors collect light intensity deviation to achieve photoelectric tracking,which can correct the tracking deviation,make sure that the solar panel is perpendicular to solar ray all along.Test results show that the system can improve the tracking accuracy,solar energy receiving efficiency has improved more than 20%,reach the goal that make full use of solar energy.
