It is an intelligent electric energy meter by expanding to the normal electric energy meter, carries out the divided chronometer price, gives the software design and adjusts the problem. We do the following work in the pletion of the thesis. (1) Analyze the requirement of the system, and design the whole structure of the system. (2) Subdivide the whole, and design each module in particular. (3) Protract schematic plot and PCB plot, and crank out experiment board. (4) Write software procedure according to hardware circuit. (5) In debugging moment, debug each software and hardware module, write testing procedure, validate the usability of the system, and finally crank out the system sample. This study will discuss about the intelligence electric energy meter in detail, and tell of the recent development of electric energy meter and the research statement in brief. This study analyzes materially the two parts: keyboard part program design and LCD show part program design, and does the explanation to the use of main chip. Also it explains the hardware total design in brief, and writes some analysis about editing the function which is used of software. Moreover this study also introduced some problems about drawing the principle diagram. For example, the connected line each chip and interface problem. Keywords: keyboard part。 clock chip 目 錄 摘 要 Abstract 1 概述 ....................................................... 1 本課題研究背景及意義 ................................................................................................ 1 國內(nèi)外研究的動(dòng)態(tài) ........................................................................................................ 1 本課題的可行性分析 .................................................................................................... 2 設(shè)計(jì)要求及預(yù)期研究成果 ............................................................................................ 2 2 系統(tǒng)簡介 ................................................... 4 系統(tǒng)總體方案設(shè)計(jì) ........................................................................................................ 4 硬件各模塊的設(shè)計(jì) ........................................................................................................ 5 主機(jī) ............................................................. 5 電腦時(shí)鐘模塊 ..................................................... 6 LCD 顯示模塊 .....................................................
