| Abstract: | In this paper, 4 photodiodes are placed on the test board. Under the sunlight, current signals produced by photodiodes, it is used to analog data acquisition. Then the microcontroller process the data. The frame of the system of analog signal＇s collection based on MCU is introduced and the hardware and software is designed in details in this paper. With the transmission mode of SPI and with the MCU of STC89C52, the transform from analog signals to digital signals, data＇s transmission and processing is achieved by this system. This design of the optical analog signal detecting and tracking program, can better determine the precise location of the angle of solar radiation, and then realize the more precise control. |
