PAGE\*MERGEFORMAT49题目:大棚内的温、湿度检测与数据处理及显示界面设计学院:组长:组员:摘要温室大棚对现在的人们来说,是非常熟悉的一个名词,因为现在我们生活中的很多花卉、蔬菜、水果都是从温室大棚中种植出来的。如何利用自动检测与自动控制系统有效的控制好温室大棚内的各种环境因子,以提高温室大棚环境的控制精度和效果,对我国温室业的发展有着不可估量的重要意义。本设计采用西门子S7-300系列可编程控制器来实现自动化控制的温室大棚。温度、湿度等环境因子在植物过程中起重要作用,在检测这环境因子的时候考虑到精度,反应速度,方便设备连接等问题,将采用温度传感器,湿度传感器对环境各项指标进行检测,传感器将检测的结果送入PLC中,由PLC将其与设定值进行比较,再发出相应的指令驱动电机﹑卷帘等设备运行或停止来调节室内的温度、湿度,从而达到智能化,自动化控制的目的。使用step7及winccflexible实现上下位连调,详细的介绍系统的特点,组成,硬件设计及软件设计等问题。关键词:蔬菜大棚;PLC;温湿度控制AbstractGreenhouseforthepeoplenowisaveryfamiliarnoun,becausenowweliveinalotofflowers,vegetables,fruitwhichfromgreenhouseshelterofplantingout.Howtouseautomaticdetectionandautomaticcontrolsystemofeffectivecontrolofgreenhousetrellisinside,inordertoimprovetheenvironmentalfactortrellisenvironmentcontrolprecisionofthegreenhouseeffectandhasbecomethegreenhouseindustryresearchinChinaatpresent.ThisdesignUSEStheSiemenss7-300PLCtorealizetheautomationcontrolgreenhousetrellis.Temperature,humidityenvironmentfactorsintheprocessofplantsplaysanimportantroleindetectingtheenvironmentalfactor,whenconsideringtheaccuracy,thereactionspeed,convenientdeviceconnectedbysuchissues,willthetemperaturesensor,humiditysensorsdetecttheindicatorsofenvironment,thesensorwilltestresultsbyPLCsentPLCcompareitwithsetting,thensendsoutthecorrespondingorder-drivenheatingelement,,thefan,ventilationwindow,fillinglightequipment,sunshadeshadeequipmentoperationorstoptoadjustindoortemperature,light,humidity,soastoachievethepurposeofintelligent,automationcontrol.DiscussPLCcontrolsystemapplicationinplantsgreenhousecanopy,Usethestep7andwinccflexibletoachievetheupperandlowersandhidetailedintroducesthecharacteristicsofthesystem,thecomposition,thehardwaredesignandsoftwaredesign.Keywords:Vegetablesgreenhouse;PLCsystem;Temperatureandhumiditycontrol目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc327180884"摘要PAGEREF_Toc327180884\hIIHYPERLINK\l"_Toc327180885"AbstractPAGEREF_Toc327180885\hIIHYPERLINK\l"_Toc327180886"第一章绪论PAGEREF_Toc32718
