基于PIC的费功率电表设计

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，己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 Mieroehip公司的单片机PIC16F946和公司生产的MCP3905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。

Abstract

[来源：http://think58.com]

Along with our country economy's development, the electric power resources are becoming the people to produce, to live gradually an essential part. But traditional electric quantity metering outfit some functions are unitary, some securities, the reliability are bad, the precision limited and so on, oneself after does not meet the modern electric quantity scientific management requirement. This topic design's digital multi-purpose duplicate tariff electric meter, mainly uses in the family or the factory electrical energy consumption survey. It not can only carry on the electrical energy measurement, also have functions and so on tariff management, communication, simultaneously has the measuring accuracy to be high, the electromagnetic compatibility performance is good, overload capacity, the power loss low status characteristic, installs when does not need the dial gauge then to use. Moreover the stability is very good, the life is long, measuring accuracy basic not temperature effect. This electrical energy table MCP3905 which and Analog Deviees Corporation produces by Mieroehip Corporation's monolithic integrated circuit PIC16F946 is a core, the entire electric instrument does not have the mechanical part, is the pure electronic electric quantity metering equipment, the reliability is extremely high.
