【摘要】 随着我国经济的发展，电力资源正逐渐成为人民生产、生活不可缺少的一部分。而传统的电量计量工具有的功能单一，有的安全性、可靠性差，精度有限等，已经不符合现代电量科学管理的要求。本课题设计的数字式多功能复费率电度表，主要用于家庭或工厂的电能消耗测量。它不仅能进行电能计量、还具有费率管理、通讯等功能，同时具有计量精度高、电磁兼容性能好、过载能力强，功耗低等特点，安装时无需校表即可使用。而且稳定性很好，寿命长，测量精度基本不受温度影响。该电能表以Microchip公司的单片机PIC16C67和Analog Devices公司生产的ADE7755为核心，整个电表没有机械部件，是纯电子的电量测量仪器，可靠性极高。设计参数严格按照GB／T15284-1994、DL／T614-1997及《江苏省电力公司数字式多功能复费率电度表技术规范》的标准执行，部分参数大大优于以上标准的要求。更多还原

【Abstract】 With the development of our country, the demand for the electricity is greater and greater between all trades and professions, unbalanced phenomenon of different time power consumption is serious day by day too. In order to alleviate the sharp electric imbalance between supply and demand of our country, regulate the load curve, improve the unbalanced phenomenon in power consumption, "sharpen peak fill out valley", to improve power consuming efficiency, to rationally utilize electric energy of the whole country. Because the traditional measuring instrument just has only one function: metering. What’s more, it has little to do with security and dependability, the precision does not match people’s needs. So 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 can be programmed for special use, such as changing fee rate, communication. And it has many strong points: the precision is very exactitude, the EMC has a better performance. In addition, low power, long life, easy fix are all its merit. The CPU is PIC16C67, which is manufactured by Microchip. The key part is ADE7755, it is a power energy metering IC with pulse output. There is no mechanical part, so the dependability is extremely good. This design keeps to GB/T15284-1994 and DL/T614-1997.更多还原
