摘　　要：介绍一种以美信片上系统71M6542F为核心的单相智能电能表的设计,给出了该电表的关键硬件电路和软件流程。该系统采用了单芯片集成系统的设计方法,打破了智能电表由计量芯片加控制芯片的常规设计思路。应用表明,该电表计量精度高、抗干扰能力强、市场前景好。The design of single-phase smart meter on the basis of Maxim＇s SoC 71M6542F is introduced. The main hard- ware circuits and software frame of the meter are given. Adopting the design philosophy of the integrated single-chip,the project breaks the traditional idea that the design of smart meter is composed of metering chip and control chip. Then, practice shows that this smart meter is high accuracy,strong anti-jamming ability and have good market prospect.
