中文摘要:

针对大型电力用户实现节能管理的需求,设计了一款基于高档AVR单片机的便携式多功能电能表,详细介绍了单片机与外围器件的接口电路和软件设计过程。利用高精度同步瞬时采样芯片MAX1320对现场电信号进行同步采集,单片机对采样信号做计算和分析,通过液晶模块和大容量数据存储设备SD卡实时显示和记录采样数据和分析结果。实验测试结果表明该设计的可行性,实现了多项电气参数的实时监测。

英文摘要:

In order to help the large electricity users with energy saving management,a new design of portable multi-functional electric meter based on advanced MCU is proposed in this paper.The program design process for MCU and interface circuits between MCU and peripheral devices are described in detail in the paper.High precision MAX1320 is used for power quality data synchronous acquisition.And the MCU is used for calculation and analysis.The data are stored in large capacity storage device and displayed in the LCD.The testing results show that the design is feasible and that the device realizes on-line monitoring of many electrical parameters.
