This design mainly uses in the ordinary indoor humiture survey. Uses the DS18B20 integration chip to take the humiture sensor. In the article has analyzed the humiture survey principle of work and the process, proposed the humiture examination system design's overall plan, has carried on the plan proof to each submodule design and compares. The hardware design uses protel the 99se software, has completed the monolithic integrated circuit smallest system, the LCD display circuit, sensor's schematic diagram and the PCB chart. The software design uses Keil uVision2, has completed the program module each module design programming, has realized to the humiture signal processing process programming and the debugging. Temperature survey scope - 40~+125℃, resolution ±0.5℃. Can meet the daily life humiture survey requirements.key words: AT89C51,DS18B20,LCD,Data acquisition,Data processing 黃河科技學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 第 III 頁(yè)目錄第 1 章 緒論 ..................................................................................................................................11.1 課題意義及發(fā)展前景 ................................................................................................................11.2 設(shè)計(jì)內(nèi)容及性能指標(biāo) ...............................................................................................................2第 2 章 系統(tǒng)器件選擇 ...........................................................................................................42.1 主控芯片介紹 .............................................................................................................................42.2 溫度傳感器的選擇 ....................................................................................................................52.2.1 DS18B20 性能特點(diǎn) .........................................................................................................52.2.2 DS18B20 內(nèi)部結(jié)構(gòu)和測(cè)溫原理 ...................................................................................62.2.3 DS18B20 使用中的注意事項(xiàng)和控制方法 ..................................................................82.3 顯示元件的選擇 ........................................................................................................................9第 3 章 硬件設(shè)計(jì) .....................................................................................................................123.1 復(fù)位電路 ...................................................................................................................................123.2 時(shí)鐘電路 ...................................................................................................................................123.3 顯示電路 ...................................................................................................................................133.4 測(cè)溫電路 ...................................................................................................................................143.5 控制電路 ...................................................................................................................................143.6 報(bào)警電路 ...................................................................................................................................153.7 整機(jī)電路及工作原理 .............................................................................................................15第 4 章 軟件設(shè)計(jì) .....................................................................................................................174.1 主程序模塊 ...............................................................................................................................174.2 溫度相關(guān)模塊 ..........................................................................................................................184.3 時(shí)間相關(guān)模塊 ..........................................................................................................................264.4 中斷相關(guān)程序 ...........................................................................................................................274.5 其他相關(guān)程序 ..........................................................................................................................28 黃河科技學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 第 IV 頁(yè)第 5 章 PROTEUS 進(jìn)行仿真 .........................................................................................315.1 PROTEUS 簡(jiǎn)介 .....................................................................................................................315.2 PROTEUS 仿真圖 .................................................................................................................31總結(jié) .....................................................................................................................................................34致謝 .....................................................................................................................................................35參考文獻(xiàn) ................................................................................................................................................36
