单片机仓库恒温恒湿监控系统的设计-详细C源代码和原理图
摘要社会向前走的越来越快，人们在生产活动中对物资的存储质量越来越看重，所以对物资存储的环境也相对的更加看重了。而防潮、霉、腐、爆是我们仓库日常管理的重心，也是评判仓库好坏的决定性参数。因为它直接决定了仓库储物的安全与否。为了维持良好的储物环境，所以对仓库的温度和湿度的监测与控制也就成了重中之重。过去仓库里面测量温度和湿度的方法是：湿度表，温度计，湿度纸等，人工进行监测，温度高了就降温，湿度高了就通风，这些方法不仅工人成本高，而且还不能实时的监测仓库的温度和湿度。当仓库温湿度不符合要求的时候也不能及时的进行更改，因而仓库储物的质量得不到足够的保证。因此大家需要一款成本低、使用简单，能够精确测出温湿度，并且对温湿度不符合标准的仓库及时做出反应的温湿度监控系统。现在单片机在我们生产生活的过程当中所占的比重越来越大，其作用也越来越被大家所认可，基于单片机的仓库温湿度监控系统由此而生。本设计的主要研究内容为：基于89C51单片机的监控系统，温度采集；湿度采集；语音报警；温湿度显示。相比于过去的温湿度采集方式而言，有测量精确，测量范围宽，读数方便等特点。关键词：89C51单片机；温度传感器；湿度传感器；温湿度显示；语音报警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目录摘要………………………………………………………………….…ⅠAbstract…………………………………………………………….Ⅱ第一章绪论……………………………………………………….…….11.1选题背景…………………………………………………….………11.2设计过程及工艺要求…………………………………………….2第二章方案的比较……………………………………………………22.1温度传感器的方案选择………………………………………….…22.2湿度传感器的方案选择……………………………………….……32.3信号采集通道的选择…………………………………………….…4第三章系统总体设计……………………………………………….….63.1信号采集………………………………………………………….73.1.1温度传感器…………………………………
