| 英文摘要: |
| 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 . |
