1、福建农林大学硕士学位论文散栏式奶牛舍降温设备控制系统姓名:董晓林申请学位级别:硕士专业:农业机械化工程指导教师:张性雄20090401福建农林大学硕士学位论文摘要本课题针对南方高温对奶牛生产的影响,对适用我国南方的散栏式牛舍降温设备控制系统进行了研究。该系统以THI(HO温湿度指数)结合湿度、日照辐射度为主控参数,并根据奶牛习性、品种及地理环境设定的各个辅助参数,使奶牛的饲养环境得到更为合理的控制,有效的降低奶牛热应激程度。为了实现系统输出控制的可靠性与稳定性,本文详细介绍了以STC89RD54为核心的单片机控制单元的硬件组成方案以及动力驱动单元的设计方案:并给出了本系统单片机软件
2、抗干扰的设计思想以及实现方法。系统包括数码管显示,支持遥控和键盘操作,良好的人机交互既满足了实时控制的要求,又使控制操作简单易行。本文对控制单元的软硬件设计的主要内容进行阐述,并对驱动单元进行了简单介绍。实践证明:本系统在散栏式牛舍中能长期稳定可靠地运行,并且取得了一定的效益:试验组牛舍内THI较对照组显著降低(P3、生产热应激降温控制系统日照辐射度抗干扰福建农林大学硕士学位论文AbstractAiIIlingatthehightemperatureinthesouthofChinawhichaffectsthedairyproduction,aworkablecontrolsystemofcoolingequipmentsindairyfarmisstudiedinthispaper.,n圮systemintroducesT】HI(temperature—humidityindex),thehumidityandirradiance嬲itschiefcontrolparameters.ands4、etsseveralauxiliaryparametersinaccordancewiththelifestyleandthebreedofdairyearleandthegeographicalenvironment.toassurethebettercontroloftherearingenvironmentofdairycattle,andreducetheheatstressofdairycattlee伍ciently.Inordertoensurethereliabilityandthestabilityoftheoutputcontrolsystem,thispaper5、expoundsthehardwarecomponentsschemeofthesingle-chipmicrocomputercontrolunitbasedonthecoreofSTC89Im54,andthedesignofthepowerdrivingunit.ItalSOpresentstheideaandmethodsofimplementationoftheanti..disturbancesoftwareforthesingle..clipmicrocomputer.ThesystemCallsupportLEDdisplay,remotecontrollerand6、keyboardoperation.Agoodhuman-computerinteractionnotonlymeetstherequirementsofreal-timecontrol,butalsomakesthecontroleasilyoperated.TmSpapermainlypresentsthehardwareandsoftwaredesignofthecontrolsystem。andbrieflyintroducesthedrivingunit.Thepracticehasprovedthat:thesysteminthedairyfarmcallworkina7、long.termstableandreliableoperation.andgainedsomebenefitsfromthesystem:theTHIintheexperimentalgroupconspicuouslylowerthanthecomparisongroup(P
