本科毕业论文（设计）题目基于单片机的万年历加温度显示设计PAGE\*MERGEFORMAT88基于单片机的万年历加温度显示设计摘要本设计将制作一种基于单片机控制的带实时温度显示、具有定时功能的电子万年历。传统的电子日历大都体积大，功耗大，显示不准确等特点。为了缩小体积，减小功耗，使其变得小巧灵敏，本设计加入了时钟芯片DS1302，可对时间进行准确记时，同时可设置定时时间，实现定时功能。另外本设计具有显示实时温度的功能。传统的温度传感器系统大都采用放大、调理、A/D转换，转换后的数字信号送入计算机处理，处理电路复杂、可靠性相对较差，占用计算机的资源比较多。本设计将采用DS18B20一线制数字温度传感器，可将温度信号直接转换成数字信号送给微处理器，电路简单，成本低，实现了时间温度同时显示的效果。最后，温度和时间都将通过12864液晶显示器进行显示。测试表明系统达到了设计要求的各项功能，各部分工作正常。关键词时钟/温度检测/单片机/温度mICROCONTROLLER-BASHEDCALENDERANDTEMPERATUREDISPLAYDESIGNABSTRACTThisdesigncreatesanelectroniccalendarwithreal-timetemperaturedisplayandtimingfunctionbasedonsinglechipcontrol.Mostoftraditionalcalendarsarecharacterizedbylargesize,highpowerconsumptionandinaccuratedisplay.Inordertoreducevolumeandpowerconsumptionandmakecalendarsbecomesmallandexquisite,thedesignaddsaclockchipDS1302,whichcanaccuratelyrecordthetimeandsetaregulartimetoachievetimingfunction.Inaddition,thisdesigndisplaysreal-timetemperaturefunction.Traditionaltemperaturesensorsystemismostlyamplified,recuperatedandA/Dconverted.Theconverteddigitalsignalisinputthecomputertobeprocessed,buttheprocessingcircuitiscomplicatedwithrelativelypoorreliabilityandoccupiesmoreresourcesofthecomputer.ThisdesignusestheDS18B20first-linesystemdigitaltemperaturesensortodirectlyconvertthetemperaturesignalintodigitalsignalandsenditthemicroprocessor,whosecircuitissimpleandlowcost,achievingthedisplayedeffectoftimeandtemperaturesimultaneously.Finally,thetemperatureandtimewillbedisplayedthroughthe12864liquidcrystaldisplay.Thetestindicatesthatthesystemhasreachedvariousfunctionsofthedesignrequirementsandeachpartoperatessmoothly.KEYWORDSclock,temperaturedetection,SCM,temperature目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc323920935"中文摘要PAGEREF_Toc323920935\hIHYPERLINK\l"_Toc323920936"英文摘要PAGEREF_Toc323920936\hIIHYPERLINK\l"_Toc323920937"1概论PAGEREF_Toc323920937\h1HYPERLINK\l"_Toc323920938"1.1万年历发展背景PAGEREF_Toc323920938\h1HYPERLINK\l"_Toc323920939"1
