光伏发电的智能取用电控制系统设计

摘要

This paper introduced an intelligent control system based on STC12C5A60S2 MCU. It can switch from the photovolta-ic power supply system to electricity network. whatˊs even more,a light sensor and a infrared sensor are integrated in the sys-tem,which can make the LED light turn on automatically when needed.%本文设计一款智能用电控制系统。利用电压采集模块对光伏板的输出电压进行采样，将采样信号输入单片机处理，使用电负载在光伏供电与市电网供电间切换；同时单片机根据红外传感器和光敏传感器的传感信号，控制继电器的开启与闭合达到智能照明的效果。
