摘  要

 稱(chēng)重技術(shù)自古以來(lái)就被人們所重視，在傳說(shuō)的黃帝“設(shè)五量”中，權(quán)衡即為五量之首。在公元前，人們?yōu)榱藢?duì)貨物交換計(jì)量，起初采用木材或陶土制作的容器來(lái)作為交換貨物的計(jì)量工具，以后又采用簡(jiǎn)單的秤測(cè)定質(zhì)量。目前，隨著生產(chǎn)力的發(fā)展，電子衡器的應(yīng)用范圍越來(lái)越廣泛，同時(shí)對(duì)電子衡器的技術(shù)要求也越來(lái)越高，電子衡器由一個(gè)單一的稱(chēng)重裝置逐漸發(fā)展成一個(gè)集稱(chēng)重、自動(dòng)控制和信息處理等為一體的綜合性的稱(chēng)重系統(tǒng)。電子稱(chēng)重儀作為智能儀器之一是計(jì)算機(jī)技術(shù)與測(cè)量技術(shù)相結(jié)合的產(chǎn)物，近年來(lái)得到迅速發(fā)展，已成為現(xiàn)代稱(chēng)重技術(shù)發(fā)展的主流。隨著新技術(shù)、新器件、新標(biāo)準(zhǔn)的不斷涌現(xiàn)和應(yīng)用領(lǐng)域的不斷擴(kuò)大，電子稱(chēng)重儀的體系結(jié)構(gòu)、設(shè)計(jì)和實(shí)現(xiàn)的方法等都在不斷地變革之中。
 電子稱(chēng)重儀主要以單片機(jī)作為中心控制單元，通過(guò)稱(chēng)重傳感器進(jìn)行模/數(shù)轉(zhuǎn)換單元，再配以顯示電路及軟件組成。本文在給出電子稱(chēng)重儀硬件設(shè)計(jì)的基礎(chǔ)上，詳細(xì)分析了軟件的控制方法。

Abstract
Weighing technology since ancient times been paid more attention in the legend of the Yellow Emperor, "the five volume set", the balance amount shall be the first five.In BC, people to exchange goods measured initially produced using wood or clay containers as a measurement tool for the exchangeof goods, and later using a simple scale to determine themass. Now, with the development of productivity, the application of electronic weighing more and more widely, while the technical requirements of electronic weighing more and more, electronic weighing scales from a single device evolved into a set of weighing, automatic control and information processing for the integrated weighing system. Electronic weighing instrument is one of intelligent instruments, as computer technology and measurement technology combined with the product of rapid development in recent years has become mainstream in the development of modern weighing technology. With the new technology, new devices, the continuous emergence of new standards and applications continues to expand, electronic weighing instrument of architecture, design and realization method are all constantly transformation.
Electronic weighing instrument mainly as a central control unit MCU, by weighing sensors magic conversion unit, which together with display circuit and software. This paper presented the hardware design of electronic weighing instrument, based on detailed analysis of the software control.
