1、基于单片机的智能电表设计基于单片机的智能电表的设计摘要随着经济的快速发展,人们生活水平不断地提高,传统的电网已经不能满足现代社会的需求。现在智能电网技术蓬勃发展,作为智能电网的一个重要组成部分,智能电表也得到很大发展。在不久的将来,智能电表必将在全国范围内安装。所以智能电表技术的研究具有重大的现实意义。传统电表只能显示总体用电量,而且需要人工抄表,浪费了大量的人力物力。智能电表的研究主要为了实现供需双方的实时通信,供方可以根据需求负荷调节电价,需方可以根据电价调节用电量。最终达到削峰填谷,节约用电的效果。本文针对电表现状,提出了基于单片机的智能
2、电表的总体设计方案。本文主要完成以下工作:提出了智能电表总体设计方案,设计了数据采集电路,运用ProtelDXP软件绘制了原理图及生成了PCB板,焊制了数据采集电路板,运用KeiluVision2编写了程序。经过调试,电路板能较准确地显示输入的电压、电流的有效值,他们的功率因数角以及实时功率。关键词:智能电表,数据采集电路,PCB板,程序设计-I-基于单片机的智能电表的设计AbstractWiththerapiddevelopmentofeconomy,peoplelifelevelcontinuouslyimprove,thetraditio
