基于单片机的事务管理系统摘要所谓事务管理系统就是主要用来做提醒，辅助以计时、秒表等的一个小系统利用MCS51单片机即可完成系统硬件需要，成本低廉，程序简单，功能丰富实用，使用率广。根据题目的设计要求，该系统要实现的功能主要有：事务提醒、定时、秒表、扬声器、小灯闪烁、键盘、液晶屏。其中事务提醒功能可重复可循环，用键盘进行输入，扬声器和小灯作为提醒作用，液晶屏输出显示。在了解了题目要求后，首先进行框图确定并且确定各模块的硬件需要以及各种元器件的需要，之后进行硬件电路的设计，同时，对软件部分的流程进行了演草和模拟，并确定参数。在此设计的最后环节，就是对所有模块的资源整合，扩展功能的实现和编程，最终得到完整的程序。关键词：单片机事务提醒编程ITransactionManagementSystemBasedonSingleChipMicrocomputerAbstractSo-calledtransactionmanagementsystemismainlyusedtodoremind,aidedbyasmallsystemsuchastiming,astopwatch.ByusingMCS51singlechipmicrocomputertocompletethesystemhardware,lowcost,simpleprogram,feature-rich,practical,andwideusage.Accordingtotherequirementsofthesubjectdesign,inordertorealizethefunctionofthesystemmainlyinclude:transactionremind,timer,stopwatch,speakers,smalllightsflashing,keyboard,LCDscreen.Thetransactionalertscanberepeatedcycle,usekeyboard,speakersandsmalllightsasareminder,LCDdisplayoutput.Afterunderstandingthetopicrequest,firsttomakesuretoblockdiagramofeachmoduleanddeterminethehardwareneedsandtheneedsofthevariouscomponents,followedbythedesignofthehardwarecircuit,atthesametime,thesoftwarepartoftheprocesshascarriedonthegrassandsimulation,andparametersweredetermined.Inthelastlinkofthedesign,whichisforallmodulesofresourceintegration,therealizationofthefunctionofextensionandprogramming,finallygetthecompleteprogram.Keywords:singlechipmicrocomputeraffairsremindprogramming目录II摘要..................................................................................................................................................IIAbstract.........................................................................................................................................III目录................................................................................................................................................IV1概述...............................................................................................................................................21.1事务管理系统的概述.........................................21.2研究课题的目的和意义.......................................31.3国内外研究现状.............................................41.4设计内容和要求.............................................41.4.1设计要求...............................................................................................................51.4.2设计内容...............................................................................................................52系统方案分析与选择论证............................................................................................................52.1主控芯片方案比较.............................................52.2显示模块方案比较............................................52.3时钟模块方案比较.............................................62.4系统最终方案确定.............................................63事务管理系统的硬件设计...........................................................................................................73.1基于单片...
