Design Of STM32 Based On Total Solar Radiometer

Total solar radiation refers to the sum in the horizontal plane to receive the solar direct radiation and sky diffuse radiation, in the meteorological data and the value of the total solar radiation is an important part can be used to study meteorology, atmospheric pollution, solar energy utilization.In this paper, the research on solar radiation, designed a kind of high precision, good stability, easy operation and high price of total solar radiometer. The system is mainly composed of solar total radiation sensor, STM32F103VET6 core microprocessor and PC software.This paper describes in total solar radiation related background, introduces the total solar radiation measurement principle and method based on the research and design of solar total radiation sensor, solar total radiation sensor made in black and white and mutually insulated sector placed platinum resistance structure, can for high precision of radiation temperature measurement. Hardware circuit design the stm32f103vet6 core circuit, analog digital conversion circuit, temperature sensor circuit, serial communication interface circuit, power supply circuit, JTAG interface circuit, LCD liquid crystal display circuit and reset circuit, software design stm32f103vet6 initialization procedure, total solar radiation sensor analog to digital conversion process, temperature sensor module procedures, LCD liquid crystal display module program and PC program. Finally, the RBF neural network model of total solar radiation temperature drift compensation. Through the establishment of the RBF neural network of temperature drift compensation, completed the network training and testing. The measured results show that the total solar radiometer has basically met the design requirements.
