【正文】 I 電子科技大學(xué) 成都學(xué)院 微電子技術(shù) 系 工程系統(tǒng) 1 設(shè)計報告 題目名稱 簡易 電子秤 小組成員： 姓名 江繼維 學(xué)號 1440710425 姓名 夏天 學(xué)號 1440710410 專 業(yè) 集成 電路設(shè)計與集成系統(tǒng) 指導(dǎo)教師 林國偉 2020 年 6 月 制 ABSTRACT II 摘 要 秤是一種在實(shí)際工作和生活中經(jīng)常用到的測量器具。 隨著計量技術(shù)和電子技術(shù)的發(fā)展 ， 傳統(tǒng)純機(jī)械結(jié)構(gòu)的桿秤、臺秤、磅 秤等稱量裝置逐步被淘汰，電子稱量裝置電子秤、電子天平等以其準(zhǔn)確、快速、方便、顯示直觀等諸多優(yōu)點(diǎn)而受到人們的青睞。 和傳統(tǒng)秤相比較，電子秤 利用新型傳感器、高精度 AD 轉(zhuǎn)換器件、單片機(jī)設(shè)計實(shí)現(xiàn)，具有精度高、功能強(qiáng)等特點(diǎn)。本課題 設(shè)計的電子秤具有基本稱重功能。該 電子秤的測量范圍為 05Kg，測量精度達(dá)到 1g，有高精度，低成本，易攜帶的特 點(diǎn) 。 電子秤采用液晶顯示數(shù)值，比傳統(tǒng)秤具有更高的準(zhǔn)確性和直觀性。另外，該電子秤電路簡單，使用壽命長，應(yīng)用范圍廣。 ABSTRACT III ABSTRACT Scale is a kind of measuring instrument which is often used in practical work and life. With the development of measurement technology and electronic technology, gradual elimination of traditional pure mechanical structure of the steelyard, scales, scales, weighing apparatus, electronic weighing apparatus electronic balance, electronic balance to accurate, rapid, convenient and intuitive display etc. many advantages by people39。s favor. Compared with the traditional scale, electronic scale using a new type of sensor, high precision AD converter, MCU design, with high precision, strong function and so on. The electronic scale designed by this paper has the basic function of weighing. The measuring range of the electronic scale is 05Kg, the measurement accuracy is 1g, with high precision, low cost and easy to carry. Electronic scale using liquid crystal display value, pared with the traditional scale has a higher accuracy and intuitive. In addition, the electronic scale circuit is simple, the service life is long, and the application range is wide. 目錄 III 目錄 第 1 章 課題整體框架 .............................................................................................. 1 課題任務(wù) ................................................................................................................... 1 課題要求 ................................................................................................................... 1 研究意義 ................................................................................................................... 1 第 2 章 設(shè)計方案 ..................................................................................................... 2 硬件系統(tǒng)框圖 ............................................................................................................ 2 傳感器模塊 ................................................................................................................ 3 MCU 控制 ................................................................................................................... 7 電源模塊 ................................................................................................................. 9 復(fù)位電路 ............................................................................................................... 10 震蕩電路 ............................................................................................................... 10 軟件設(shè)計 .
