（單片機倉庫恒溫恒濕監(jiān)控系統(tǒng)的設(shè)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(chǎn)活動中對物資的存儲質(zhì)量越來越看重，所以對物資存儲的環(huán)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(shù)。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(huán)境，所以對倉庫的溫度和濕度的監(jiān)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(jiān)測，溫度高了就降溫，濕度高了就通風(fēng)，這些方法不僅工人成本高，而且還不能實時的監(jiān)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(zhì)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(yīng)的溫濕度監(jiān)控系統(tǒng)。現(xiàn)在單片機在我們生產(chǎn)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(jiān)控系統(tǒng)由此而生。本設(shè)計的主要研究內(nèi)容為：基于89C51單片機的監(jiān)控系統(tǒng)，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(shù)方便等特點。關(guān)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(shè)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(tǒng)總體設(shè)計……………………………………………….….63.1信號采集………………………………………………………….73.1.1溫度傳感器…………………………………
