华科学院本科毕业设计（论文）I基于单片机的全自动洗衣机控制系统设计摘要随着数字技术的快速发展，洗衣机成为家庭中不可或缺的家用电器。因此，设计了基于单片机的全自动洗衣机控制系统。本系统实现了对洗衣机整个洗衣过程的控制,包括用户参数输入,洗衣,脱水和结束报警四个阶段.控制系统主要由电源电路，单片机控制系统和外部硬件三大模块组成。通过单片机的控制，外部硬件随着用户参数的输入，洗衣机按照用户的选择要求进行运作。本系统给AT89S52单片机载入软件程序后,能够实现全自动洗衣机的基本功能.使得洗涤、漂洗、排水、脱水等各种功能的操作都不需要手动。并可以通过选择洗涤方式来选择时间，还可以选择洗涤的强弱等多种方式。控制器通常设有强洗、弱洗两种洗涤程序，对不同的衣物可提供用户选择。本设计实现了多种洗衣功能，能够满足现代家庭的基本洗涤要求，具有一定的实用性。关键词：单片机89S52；洗涤；全自动洗衣机；控制器马君：基于单片机的全自动洗衣机控制系统设计II华科学院本科毕业设计（论文）IIIDesignofcontrolsystemofautomaticwashingmachinebasedonthemicrocontrollerAbstractWiththerapiddevelopmentofdigitaltechnology,washingmachinehasbecomeindispensablehouseholdappliances.Therefore,thedesignofthecontrolsystemofautomaticwashingmachinebasedonsinglechipmicrocomputer.Thissystemrealizesthecontrolofthewashingmachineandthewholewashingprocess,includinguserinputparameters,washing,dehydrationandendalarmfourstages.Thecontrolsystemismainlycomposedofapowersupplycircuit,SCMcontrolsystemandtheexternalhardwarethreemodules.ThroughtheMCUcontrol,externalhardwarewithuserinputparameters,washingmachineaccordingtotheuser'schoiceforoperation.ThissystemdownloadingtheprogramtoAT89S52microcontroller,toachievethebasicfunctionsofautomaticwashingmachinewashing,rinsing,drainage.So,dehydrationandothervariousfunctionaloperationdoesnotneedmanual.Andcanchoosethewashingwaytochoosethetime,canalsochoosethewashingstrengthetc..Thecontrollerusuallyprovidedwithastrong,theweakwashwashtwokindsofwashingprocedures,fordifferentclothingcanprovideuserselection.Designandimplementationofthevariouswashingfunction,cansatisfythebasicwashingtherequirementsofthemodernfamily,hasacertainpracticality.KeyWords:Singlechip89S52;washing;fullautomaticwashingmachine;controll马君：基于单片机的全自动洗衣机控制系统设计IV华科学院本科毕业设计（论文）V目录摘要............................................................................................................................................IAbstract.........................................................................................................................................III第1章绪论...................................................................................................................................11.1课题的目的和意义...........................................................................................................11.2洗衣机的发展全景及待解决的问题...............................................................................11.3课题设计任务与要求.......................................................................................................3第2章全自动洗衣机的设计方案...............................................................................................52.1系统方案选择...................................................................................................................52.2具体设计方案...................................................................................................................72.2.1按键........................................................................................................................72.2.2洗衣机自检............................................................................................................72.2.3洗衣程序................................................................................................................82.2.4显示........................................................................................................................82.3控制系统的功能...............................................................................................................8第3章系统硬件设计...................................................................................................................93.1系统硬件总体设计...........................................................................................................93.2各单元电路设计.............................................................................................................153.2.1电源电路..............................................................................................................153.2.2控制电路..............................................................................................................153.2.3检测电路..............................................................................................................173.2.4执行电路..............................................................................................................173.2.5显示电路..............................................................................................................193.2.6蜂鸣器报警电路..................................................................................................203.3电路设计及本章小结.....................................................................................................21第四章系统软件设计.................................................................................................................234.1软件主程序设计.............................................................................................................234.2软件子程序设计............................................................................................
