摘要
绍了一种三相电能计量系统,以ATT7022B为计量芯片,采用Freescale单片机MC68HC908LJ12为核心。根据系统的设计要求确定了键盘模块的硬件电路和软件程序,实现了测量有功功率、无功功率、视在功率等多种功能。
In this paper,a new type three-phase energy measurement system which based on the electrical energy measurement chip ATT7022B and Freescale Microcontroller MC68HC908LJ12 is introduced.Based on the whole system scheme,the paper describes the hardware and the software process of every part.This system has functions to measure active energy,reactive energy,apparent energy and so on.
