摘　　要：为提高太阳能的转换效率,设计了基于四象限探测器的太阳跟踪装置,采用视日运动轨迹跟踪与光电跟踪相结合的方式对太阳进行跟踪,利用光电二极管检测作为反馈实现两种跟踪方式间的转换。设计了一套能自动使太阳能电池板与太阳光线保持垂直的跟踪系统,实现了最大效率的太阳能利用。试验结果表明,该系统跟踪精度高,可实现各种天气状况下全天候全自动跟踪,跟踪器稳定,效果满意。A sun-tracker device is designed based on the four-quadrant detector in order to improve the conversion efficiency of the solar energy. The tracking of sun is achieved by using the combination of both calendar-check tracking and light-electric tracking. And the conversion between the two tracking ways is achieved by using a photo electricity diode examination as feedback. A tracking system to assure the solar panels vertical to the solar incident angle to improve the absorbing efficiency is designed. After some experiments, we draw the conclusion that the accuracy of this system is high. No matter under any weather, this device can run stably and achieve satisfactory results.
