摘要一般说来，像万年历、闹钟等生活必需功能都能在手机或网络中得到很好的体现，人们似乎也没有必要再掏腰包去购买所谓的专用万年历的产品，但有一点不可忽视，随着人们生活水平的提高，人们对产品的要求不再仅仅局限于功能的强大，更希望所使用的产品要简洁、实用，甚至能起到装饰作用，体现一个人的品味，就像数码相册这个成功的创意一样。本作品就是基于这样一种简洁、实用的设计理念，希望通过简单的操作，小巧的外观，是每一个用过的人都能产生深刻的印象。为把作品的成本压到最低，设计过程中的很多功能都使用单片机来实现，外围也都采用市场上较为普及的芯片来做。具体用到了LCD12864作为显示屏，DS1302作为时钟计算器件，DS18B20作为温度感应器件，蜂鸣器作为报时器件，当然少不了AT89S51作为主控部分。关键词：电子日历、MCU、菜单AbstractIngeneral,somemust-functionslikecalendersandclocksarecontainedincellophanesandInternet,soitseemsthatthereisnoneedtobuysomewhatwecalledcalenders.However,withtheimprovementofthequalityoflife,theneedofpeoplearenotonlylimitedinthestrongfunctionsofsomeproduction,they,however,prefertosomeproductionthatiseasy,practical,andsometimesevencanactasdecoration.They'dbetterreflectconsumers'staturejustasthefantasyoftheelectronicalbum.Thissystemisbasedontheopinionofeasinessandutility.Itisexpectedtoattractcustomersbyitseasyoperationandtinyappearancesothatitcanmakesomeimpressiononcustomers.Inodertomakethecostaslowaspossible,manysingle-chipmicrocomputersareappliedwhichareusualinmarket.Indetail,whatweuseis:LCD12864asaLCD,DS1302asatimecalculator,DS18B20astemperaturesensor,abuzzerasaaburglaralarm,andaAT89S51asthemainpartofthesystem.目录论文总页数为15页1引言.............................................................................................................................11.1作品背景..........................................................................................................11.2市场现状..........................................................................................................11.3本作品的意义..................................................................................................12总体方案设计.............................................................................................................22.1方案论证与比较..............................................................................................22.2操作流程..........................................................................................................33单元电路设计.............................................................................................................73.1液晶显示设计..................................................................................................73.2按键操作设计..................................................................................................83.3温度测量模块设计..........................................................................................83.4时钟模块设计..................................................................................................93.5报时模块设计................................................................................................103.6电源模块设计................................................................................................103.7系统控制模块设计........................................................................................114软件设计..........................................
