摘要论文运用嵌入式应用系统技术和智能检测与控制技术，设计了基于单片机技术的智能型感应式冲水系统。该冲水系统利用传感器检测人体发出的红外线信号，由单片机接收并作出智能判断，控制电磁阀的开启，然后经内部软件程序设定一定时间的延时，关闭电磁阀。此种设计方案可以达到环保、节水的目的，克服了现有公厕冲水系统浪费水资源及手动操作不卫生的不足。论文论述了设计的理论基础、论证了设计方案，讨论了PIC12C508A单片机、嵌入式系统及其开发技术、智能检测与控制技术。论述了基于单片机的人体红外探测智能冲厕硬件电路设计和软件程序设计，抗干扰设计及软硬件调试和组装等。对硬软件抗干扰技术和PC板的抗干扰设计做了详细论述。达到了整个系统实现全自动操作，免除人为动作，既能满足冲厕的卫生要求，又最大限度地节约了水资源的目的。【关键词】单片机；红外检测；智能冲厕；节水；1AbstractPaperstheuseofembeddedsystemtechnologyandintelligentapplicationofdetectionandcontroltechnology,designtechnologybasedonsingle-chipsmartsensorflushingsystemtype.Theflushingsystemusesthehumanbodydetectionsensoroftheinfraredsignalsentbythesingle-chipreceiverandmakeintelligentjudgments,controlsolenoidvalvetoopen,andthentheproceduressetbytheinternalsoftwareofacertainperiodoftimedelaytoclosethesolenoidvalve.Thisdesigncanachieveenvironmentalprotection,waterconservationpurposes,toovercometheexistingpublictoiletsflushingwastewatersystemandinadequatemanualunsanitary.Paperdiscussesthetheoreticalbasisfordesign,designverificationprogramtodiscussthePIC12C508Amicrocontroller,embeddedsystemsandthedevelopmentoftechnology,intelligentdetectionandcontroltechnology.Onthehumanbodybasedonthesingle-chipinfrareddetectionIntelligentflushinghardwarecircuitdesignandsoftwareprogramming,hardwareandsoftwaredesignandanti-debuggingandassembly.Hardwareandsoftwareofanti-jammingtechnologyandanti-jammingdesignofPCboarddiscussedindetail.Theentiresystemtoachievefullyautomaticoperation,fromhumanaction,bothtomeetthehealthrequirementsforflushing,butalsotomaximizethepurposeofconservationofwaterresources.Keywords:SCM；infrareddetection；smartflushing；waterconservation；2目录第一章绪论..................................................................................................................51.1课题研究的背景、目的及意义......................................................................51.1.1中国水资源现状..........................................................
