摘　　要：依据太阳光线变化的缓慢性、间歇性及环境天气的变化,设计了一种光电跟踪和太阳轨道跟踪相结合的实时阳光跟踪系统,采用阵列光电传感与时钟计算组合方法,分析太阳运动轨迹、角度姿态对阳光跟踪与能量转换效率的影响,探讨四元阵光电传感对太阳运动角度与方向变化的阳光跟踪光电控制系统原理,通过光照强弱与时钟计算太阳历史位置进行精确跟踪。实验表明,系统能实现太阳位置的二维实时跟踪和太阳能电池姿态控制,在光强大范围变化条件下也可以精确的跟踪,大大提高了太阳光的利用。Based on the tardiness and intermittency of the changes of the sun rays and the environmental changes,a sunlight real- time tracking system that combines photoelectric tracking and sun orbital tracking was designed. It adopted the method that combines array photocell sensor and clock calculation to analyze the trajectory of the sun and how the angle attitude affects the efficiency of sun tracking and energy conversion. It discussed the solar tracking photoelectric tracking control system theory of how the four-element array changes with the angle of the sun. The sunshine was tracked though illumination changes and historical trajectory. The experiment shows that it can achieve the two- dimension real- time tracking and battery management of the sun position and make accurate tracking even on the condition that the light intensity changes within a wide range,which greatly improves the utilization rate of the sunlight.
