單片機倉庫恒溫恒濕監控系統的設計-詳細C源代碼和原理圖
摘要社會向前走的越來越快,人們在生產活動中對物資的存儲質量越來越看重,所以對物資存儲的環境也相對的更加看重了。而防潮、霉、腐、爆是我們倉庫日常管理的重心,也是評判倉庫好壞的決定性參數。因為它直接決定了倉庫儲物的安全與否。為了維持良好的儲物環境,所以對倉庫的溫度和濕度的監測與控制也就成了重中之重。過去倉庫里面測量溫度和濕度的方法是:濕度表,溫度計,濕度紙等,人工進行監測,溫度高了就降溫,濕度高了就通風,這些方法不僅工人成本高,而且還不能實時的監測倉庫的溫度和濕度。當倉庫溫濕度不符合要求的時候也不能及時的進行更改,因而倉庫儲物的質量得不到足夠的保證。因此大家需要一款成本低、使用簡單,能夠精確測出溫濕度,并且對溫濕度不符合標準的倉庫及時做出反應的溫濕度監控系統?,F在單片機在我們生產生活的過程當中所占的比重越來越大,其作用也越來越被大家所認可,基于單片機的倉庫溫濕度監控系統由此而生。本設計的主要研究內容為:基于89C51單片機的監控系統,溫度采集;濕度采集;語音報警;溫濕度顯示。相比于過去的溫濕度采集方式而言,有測量精確,測量范圍寬,讀數方便等特點。關鍵詞:89C51單片機;溫度傳感器;濕度傳感器;溫濕度顯示;語音報警IIAbstractSocietyforwardfasterandfaster,peopleintheproductionofmaterialsstoragequalityaremoreandmoreimportant,sothematerialstorageenvironmentisrelativelymoreimportant.Andmoisture,mildewandrot,blastingisthefocusofourwarehousedailymanagement,alsoisgoodorbadthedecisiveparameteruationwarehouse.Becauseitdirectlydeterminesthesafetyofthewarehousestorageornot.Inordertomaintainagoodstorageenvironment,sothetemperatureandhumiditymonitoringandcontrolofthewarehousehavebecometoppriority.Insidethewarehousetomeasurethetemperatureandhumidityoftheis:hygrometer,thermometer,moistureofpaper,suchasartificialmonitoring,hightemperaturecooling,andventilationtohumidityishigh,costishigh,thenotonlyworkersbutalsocannotbereal-timemonitoringofthetemperatureandhumidityofwarehouse.Whenthewarehousetemperatureandhumidityisnotinconitywiththerequirementscanttimelymakechanges,andthusthequalityofthewarehousestorageisnotenough.Soweneedalowcost,simpletouse,canaccuratelymeasuretemperatureandhumidity,andtemperatureandhumiditydonotcontothestandardofwarehousetorespondinatimelymannerofthetemperatureandhumiditymonitoringsystem.Microcontrollerintheprocessofourproductionandlivingnowaccountsformoreandbigger,theeffectisbecomingmoreandmorerecognizedbyeveryone,thewarehousetemperatureandhumiditymonitoringsystembasedonsinglechipmicrocomputercomes.Themainresearchcontentofthisdesignis:monitoringsystembasedon89c51,temperatureacquisition;Humidityacquisition;Voicealarm;Temperatureandhumiditydisplay.Wayofcollectingthedataoftemperatureandhumiditythaninthepast,themeasurementprecision,widemeasuringrange,easyreading,etc.Keywords:89C51;thetemperaturesensor;Humiditysensor;Temperatureandhumiditydisplay;VoicealarmIII目錄摘要………………………………………………………………….…ⅠAbstract…………………………………………………………….Ⅱ第一章緒論……………………………………………………….…….11.1選題背景…………………………………………………….………11.2設計過程及工藝要求…………………………………………….2第二章方案的比較……………………………………………………22.1溫度傳感器的方案選擇………………………………………….…22.2濕度傳感器的方案選擇……………………………………….……32.3信號采集通道的選擇…………………………………………….…4第三章系統總體設計……………………………………………….….63.1信號采集………………………………………………………….73.1.1溫度傳感器…………………………………
