（單片機(jī)倉(cāng)庫(kù)恒溫恒濕監(jiān)控系統(tǒng)的設(shè)計(jì)-詳細(xì)C源代碼和原理圖）
摘要社會(huì)向前走的越來(lái)越快，人們?cè)谏a(chǎn)活動(dòng)中對(duì)物資的存儲(chǔ)質(zhì)量越來(lái)越看重，所以對(duì)物資存儲(chǔ)的環(huán)境也相對(duì)的更加看重了。而防潮、霉、腐、爆是我們倉(cāng)庫(kù)日常管理的重心，也是評(píng)判倉(cāng)庫(kù)好壞的決定性參數(shù)。因?yàn)樗苯記Q定了倉(cāng)庫(kù)儲(chǔ)物的安全與否。為了維持良好的儲(chǔ)物環(huán)境，所以對(duì)倉(cāng)庫(kù)的溫度和濕度的監(jiān)測(cè)與控制也就成了重中之重。過(guò)去倉(cāng)庫(kù)里面測(cè)量溫度和濕度的方法是：濕度表，溫度計(jì)，濕度紙等，人工進(jìn)行監(jiān)測(cè)，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(shí)時(shí)的監(jiān)測(cè)倉(cāng)庫(kù)的溫度和濕度。當(dāng)倉(cāng)庫(kù)溫濕度不符合要求的時(shí)候也不能及時(shí)的進(jìn)行更改，因而倉(cāng)庫(kù)儲(chǔ)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(jiǎn)單，能夠精確測(cè)出溫濕度，并且對(duì)溫濕度不符合標(biāo)準(zhǔn)的倉(cāng)庫(kù)及時(shí)做出反應(yīng)的溫濕度監(jiān)控系統(tǒng)?，F(xiàn)在單片機(jī)在我們生產(chǎn)生活的過(guò)程當(dāng)中所占的比重越來(lái)越大，其作用也越來(lái)越被大家所認(rèn)可，基于單片機(jī)的倉(cāng)庫(kù)溫濕度監(jiān)控系統(tǒng)由此而生。本設(shè)計(jì)的主要研究?jī)?nèi)容為：基于89C51單片機(jī)的監(jiān)控系統(tǒng)，溫度采集；濕度采集；語(yǔ)音報(bào)警；溫濕度顯示。相比于過(guò)去的溫濕度采集方式而言，有測(cè)量精確，測(cè)量范圍寬，讀數(shù)方便等特點(diǎn)。關(guān)鍵詞：89C51單片機(jī)；溫度傳感器；濕度傳感器；溫濕度顯示；語(yǔ)音報(bào)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(jì)過(guò)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(hào)采集通道的選擇…………………………………………….…4第三章系統(tǒng)總體設(shè)計(jì)……………………………………………….….63.1信號(hào)采集………………………………………………………….73.1.1溫度傳感器…………………………………
