Abstract: In view of the high energy consumption and the lack of real-time monitoring system, a power measurement system based on atmegal16 was designed and implemented to survey server's key power components. Consumption of server machine, hard disk, CPU and memory were separately gauged in real-time and displayed in curves. The system used perforated-type external components, without insertion loss, so as to achieve the purpose of measuring non-destructively. The experimental results show that this system is lossless and stable, and the measurement result is consistent with the standard power valuation, which can reflect power change of server's key components in real-time.

摘要： 针对计算机能耗较多、功率实时监测系统较为缺乏的不足，提出基于atmegal16单片机的服务器关键能耗部件测量系统的设计方案和实现方法。该系统能分别对服务器整机、硬盘、CPU与内存的功耗进行实时测量并最终显示实时变化曲线；传感器模块采用穿孔式外接元器件，无插入损耗，从而达到测量无损的目的；单片机软件部分基本采用中断方式完成。实验结果表明：该系统测量无损且运行稳定，测量结果与标准功率计值保持一致，能够实时反映服务器关键部件功率的变化情况。
