1北京交通大学海滨学院毕业设计（论文）基于单片机的电热水器水温水位控制系统设计摘要随着人们生活水平的提高，各种热水器的使用已相当普及。与之相配套的控制仪也相继问世。然而，目前市场上的各种热水器控制电路还与理想要求相差甚远。因此我设计了新型的热水器水温水位控制系统来满足于当今的需求，该热水器智能控制系统主要由80C51单片机控制、DS18B20温度传感器、独立键盘、LED数码管和报警系统组成。该系统能测量并显示水温、设置水温范围，若水温不处于所设置的水温范围则报警，同时还能对水位进行设置及加水，先设置好需要加水的水位段数，单片机会根据这个数进行判断是否加水。通过软硬件调试使以上所述功能都能正常实现。本次设计是对水温水位控制系统的智能化改进，采用单片机对其水温水位参数进行控制，提高了电器的工作稳定性，同时引进了数字传感器对水温进行数据采集，这样也就提高了系统的控制精度，以其自身的控制精度高、稳定性好和成本低的独特优点在今后将会由广泛的实用价值，其基于单片机的改进方法也具用广泛的应用意义。关键词：单片机；DS18B20；水温水位控制2张胜：基于单片机的电热水器水温水位控制系统设计3北京交通大学海滨学院毕业设计（论文）ElectricWaterHeaterWaterTemperature-LevelControlSystemBasedonSCMAbstractWiththeimprovementofpeople'slivingstandard,theuseofvariouswaterheaterisverypopular.Controlapparatusandthematchedfield.However,thecurrentmarketonthevariouswaterheatercontrolcircuitandtheidealrequirementsdifferveryfar.Soidesignanewtypeofwaterheaterwaterlevelcontrolsystemtomeetthesemandinnowdays.Thedesignofsolarwaterheatersintelligentcontrolsystemismainlycomposedofsingle-chip80C51,DS18B20temperaturesensor,anindependentkeyboard,LEDandalarmsystem.Thesystemcanmeasureanddisplaywatertemperature,settherangeofwatertemperature,ofthewatertemperatureisnotintherangeofsettingtemperatureisalarming.Atthesametime,youcansetthewaterlevelandaddwater,first,needtosetupthewaterlevelabovethewater,single-chipwilldeterminewhetheraddthewaterornotaccordingtothenumber.Throughhardwareandsoftwaredebugging,theabovefunctionscanbenormal.Forotherrelatedparameters,italsohasacertainmeaningusing.Therevivificationofthewatercontrolsystemisanintelligentproduct.Toitsowncontrolofhighprecision,stabilityandlowcostoftheadvantages,inthefuturetherewillbeawiderangeofpracticalvalue.Thedesignofthewatertemperaturecontrolsystemistoimprovetheintellectualized.Amonolithicintegratedcircuitsistocontrolthelevelofparameterandimprovethestabilityoftheelectricalwork,andmeantime,What’smore,itsbasedonsinglewaysofimprovementhavewideapplicationmeaning.Keywords:singlechip;waterlevel’sexamination;watertemperature’sexamination目录4张胜：基于单片机的电热水器水温水位控制系统设计摘要....................................................................1Abstract....................................................................2第1章绪论.............................................................-1-1.1选题的意义........................................................-1-1.2电热水器发展现状..................................................-1-1.3课题任务..........................................................-3-第2章系统设计方案....................................................-4-2.1设计原理..........................................................-4-2.1.1系统原理.......................................................-4-2.1.2子系统工作原理.................................................-4-2.2设计方案..........................................................-5-2.2.1系统设计方案的选择.......
