设计题目：基于PLC的智能全自动洗衣机系统设计摘要在国内社会经济迅猛发展过程中，大众的生活水平也日益改善，人们的物质条件越来越好，因而对精神层面有了更高的需求。经济全球化的发展也促使各国科技不断交流，现代科技领域生机勃勃，科技的发展辐射到了大众生活中的方方面面，其中智能化、自动化逐渐成为家居产品发展的主流，不少的电器家具都有了不同程度的升级转型。作为常用家庭电器之一的洗衣机，如果能引进新型自动化、智能化技术，必将满足当下人们对生活便捷性、舒适性的需求。许多电器产品的内部都包含着控制芯片，洗衣机也不例外，而PLC作为可编程逻辑控制器，同时也作为电器的核心控制芯片，能够满足人们对洗衣机功能多样、工作稳定的需求，因此，本系统将基于PLC开发出一款智能全自动洗衣机系统。PLC涉及到的技术内核是计算机技术，能够实现对设备的自动化控制，具有功能强大、性能稳定、体积紧凑、易于操作等优点。本文采用S7-300系列的PLC，对硬件以及程序这两部分内容进行了具体的设计，基于此，开发了一款系统结构较为简单的全自动洗衣机控制系统，该系统能够完成完整的衣服洗涤流程，包括六个工作环节：第一，进水；第二，洗涤；第三，排水，第四，脱水。第五，报警；第六，停机。本文所设计的洗衣机通过可编程序控制器来实现洗涤过程，满足了对洗衣机运行的智能控制，对实现一流全自动洗衣机有了具体的实践，相信全自动洗衣机将会有更广阔的市场前景。关键词：PLC;洗衣机;可靠性；全自动;AbstractIntheprocessofrapiddomesticsocialandeconomicdevelopment,thepeople'slivingstandardsarealsoimprovingdaybyday,people'smaterialconditionsaregettingbetterandbetter,sothereisahigherdemandforspirituality.Thedevelopmentofeconomicglobalizationhasalsopromptedthecontinuousexchangeofscienceandtechnologyinvariouscountries.Thefieldofmodernscienceandtechnologyisvibrant,andthedevelopmentofscienceandtechnologyhasradiatedintoallaspectsofpubliclife.Amongthem,intelligenceandautomationhavegraduallybecomethemainstreamofthedevelopmentofhouseholdproducts.Manyelectricalappliancesandfurnitureareavailable.Upgradeandtransformationtovaryingdegrees.Asoneofthecommonlyusedhouseholdappliances,washingmachines,ifnewautomationandintelligenttechnologiescanbeintroduced,willsurelymeetpeople'sneedsforconvenienceandcomfortinlife.Manyelectricalproductscontaincontrolchips,andwashingmachinesarenoexception.PLC,asaprogrammablelogiccontroller,isalsothecorecontrolchipofelectricalappliances.Itcanmeetpeople’sneedsforwashingmachineswithdiversefunctionsandstablework.ThesystemwilldevelopanintelligentfullyautomaticwashingmachinesystembasedonPLC.ThetechnicalcoreinvolvedinPLCiscomputertechnology,whichcanrealizeautomaticcontrolofequipment,andhastheadvantagesofpowerfulfunctions,stableperformance,compactsize,andeasyoperation.ThisarticleusestheS7-300seriesPLCtospecificallydesignthetwopartsofthehardwareandtheprogram.Basedonthis,afullyautomaticwashingmachinecontrolsystemwitharelativelysimplesystemstructureisdeveloped,whichcancompletethecompleteclotheswashingprocess.,Includingsixworklinks:first,waterintake;second,washing;third,drainage,fourth,dehydration.Fifth,alarm;sixth,shutdown.Thewashingmachinedesignedinthispaperrealizesthewashingprocessthroughtheprogrammablecontroller,whichsatisfiestheintelligentcontrolofthewashingmachineoperation,andhasconcretepracticeforrealizingthefirst-classfullyautomaticwashingmachine.Ibelievethatthefullyautomaticwashingmachinewillhaveabroadermarketprospect.KEYWORDS：PLC;Washingmachine;Reliability;Fullyautomatic;目录第一章绪论.................................................................................
