Design of the Photoelectric Energy Conversion Data Acquisition System Based on Microprocessor

The paper introduced the photoelectric energy conversion system,which converted the solar energy into electricity and stored it in battery,sending the energy to the loads by controlling model.The system provided evidences for the energy distribution of loads,the energy consumption of system and the calculation of efficiency parameters through data collection and processing.The C8051F040 Single chip micro-computer was applied for the main chip,collecting voltage,current,temperature,humidity and light strength.These data were sent to the C8051F040 in terms of analog signal and digital signal,displaying on the LCD.The result showed that this converter had excellent accuracy of data collection,characterized by good reliability and lower power loss with high value of industrial application.
