太阳光入射方向的检测与太阳能电池板方位控制系统

太阳能电池板方位控制系统由光敏检测电路、单片机和步进电机等部件组成,其中光敏检测电路采集入射光方向信息,并将其转化成电信号。当入射光线与检测标杆形成角度差时,标杆阴影遮挡光敏电阻受光面,系统通过检测被遮挡的位置,确定太阳能电池板的偏移方向。检测信号经过调理电路、单片机处理后,输出控制信号控制步进电机在水平、仰角方向转动,使太阳能电池板正对太阳光,以获取最大光能。

The Control System of Detecting Sunlight Incidence Direction and Adjusting Solar Panel Orientation

Wide application of sun energy will bring endless benefits to human society ,but its efficiency has been an urgent prob-lems needed to study and solve , and how to more effectively get solar energy per unit time has practical significance .The sun light incidence direction detection and control system is composed of photosensitive resistance , MCU and stepper motor etc , in which the photoresistor detecting circuit acquires incident light direction information , and the optical signal was changed into elec-trical signal .When the detection benchmark has angle difference with incident ray in detection system , benchmarking can pro-duce shadows on photosensitive resistance , and the detection circuit can detect the blanched position , the direction of solar panels can be determined .After the signal goes through handling circuit , MCU, the control signals was formed to control stepper motor actuator runing in horizontal , or elevation direction ,to make solar panels facing the sunlight incident direction , so as to ultimately get the most sun energy .
