文章论述了光能量转换系统,将太阳能转换成电能并存储在蓄电池里,通过控制将转换的能量传输给负载;通过数据的采集和处理为负载的能量分配、系统的能耗、效率等参数的计算提供依据;设计了基于单片机为主控芯片的数据采集与处理模块系统,通过采集电压、电流、温度、湿度和光强度数据,以模拟信号或是数字信号的形式传输到C8051F040单片机中,并在液晶显示屏上显示出来;实验结果表明,该系统有良好的采集数据精度和可靠性,运行功耗低,具极高的工业实际应用价值。

The paper introduced the photoelectric energy conversion system, the system converts the solar energy into electricity and stores it in battery, sends the energy to the loads by controlling model. The system provides 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 is applied for the main chip, collecting voltage, current, temperature, humidity and light strength, these data are sent to the C8051F040 in terms of analog signal and digital signal, and displaying on the LCD. The result of test shows that this converter makes the system design simple and is characterized by high precision and good reliability and lower power loss. It will he widely required in application.
