基于AVR的智能节能插座设计

Design of Intelligent Energy-saving Socket Based on AVR

为了能够在计算机关机或待机情况下有效切断外设电源,达到节能的目的,利用低功耗高性能的AVR mega 48作为控制电路的核心,通过检测计算机待机电流的方法,设计了一种可靠性高、性能好的计算机智能节能插座,并对智能节能插座的控制原理进行了详细的分析。将计算机接到所设计的插座上测试,结果表明:智能插座能正确监测计算机的运行状态,并根据监测状态值有效的切断外设电源,同时具有定时开关的功能,实现了外设的零待机功率。

An intelligent socket for computer energy-saving with high reliability and good performance, which uses AVR mega 48 as the core of the control circuit, is designed to cut off the peripheral power supply effectively by detecting： the standby current of the computer under the condition of shutdown or standby to achieve the purpose of energy saving. The principle of the intelligent socket is analyzed. Connecting the computer to the socket to test, the results show that the intelligent socket can monitor the operating status of computer properly, and cut off the peripheral power supply effectively based on the monitoring state value. It also has the function of time switch, which enables the zero standby power of the peripheralS：
