智能型复费率数字电能表的设计

采用Microchip公司的单片机PIC16C67和Analog Devices公司的ADE7755为核心，设计了单相多功能复费率数字电度表，主要用于家庭或工厂的电能消耗测量．它不仅具有电能计量、费率管理、通讯等功能，同婴苎有计量精度高、电磁兼容性能好、过载能力强、功耗低、安装时无需校表、稳定性好、寿命长，以及测量精度高等特点。

The Design on the Intelligent & Multi-rate Watt-hour Meter

With the development of China's national economy,electric power is becoming one of the most important sources in our life and manufacture.But the traditional measuring tool has only metering function.What's more,it has little to do with security and reliability,the precision does not meet people's need.The task of my work is to design a digital single-phrase electric power measure instrument with subsection fee rate.It is not only used for metering,but also programmed for special use,such as change fee rate,communication.And it has many strong points,the precision being very exactitude,the EMC having a better performance.In addition,low power,long life,easy fixing are all its merits.The CPU is PIC16C67,which is manufactured by Microchip.The key part is ADE7755,which is a power energy metering IC with pulse output.There is no mechanical part,so the reliability is extremely high.
