基于单片机的排队叫号系统设计

I摘要排队叫号系统是针对银行、工商、税务、通讯、政府机构等部门的大厅工作流程设计的，是利用电脑的科学管理客户排队的系统，可以解决不同的客户在业务过程中所遇到的拥挤的现象，为客户办理业务带来很大的便利。本次毕业设计要求的排队系统主要由单片机，完整的键盘，显示电路，蜂鸣器电路组成。系统采用仿真软件protues对排队叫号系统进行模拟仿真，客户使用按键输入信息，单片机接收到输入的信息后，会在排队的人数上面加1，并将最终的号码通知客户，客户拿到号码到等候室等候呼叫自己的号码。在此期间取票机会将客户刚刚接收的信息发送到主机，工作人员接收数据后并作出应答，通过按键通知客户到所在窗口办理业务，此时取票机准备下一次的取号，整个过程非常迅速。为了更加人性化的服务于客户，企业还可以设置座椅，并且提供报纸、书刊，放置公司的相关业务介绍。增加客户等候时的趣味性的同时，还可以让客户更加深入的了解本公司的业务办理，可谓一举两得。此过程有效地避免了因拥挤带来的一系列问题，提高了工作效率。论文主要研究了排队叫号系统的实现方法，研究结果对现实具有重要的指导意义。研究结果肯定了单片机完成排队叫号系统的可能性。本文的特色是采用通俗易懂的语言，向大家介绍了排队叫号系统的原理以及设计思路，对日常的生产生活具有一定的影响。关键字：protues排队叫号单片机人性化IIAbstractQueuingsystemisworkinginthelobbyforbanks,industryandcommerce,taxation,telecommunications,governmentagenciesandotherdepartmentsofdesign,cansolveallkindsofqueues,crowdedandchaoticphenomenaforbusinesscustomersintheencounterforcustomersbringgreatconvenienceforbusiness.Thedesignrequirementsforgraduationtocompletequeuingsystemconsistsofmasterandslavesystem,keyboard,displaypartofthecircuit,buzzercircuit,etc..Protuessystemusingsimulationsoftwaretoachievethenumberqueuingsystem'ssimulation,customersusingthekeyinputinformation,themicrocontrollerreceivesinputinformationwillbeaddedtotheabove,anumberofqueuedandwillnotifythecustomertheultimatenumber,customersgetnumberstothewaitingroomtowaitfortheircallnumbers.Opportunityticketswillbesentduringthisperiodthecustomerhasjustreceivedinformationtothehost,andthestaffmadetheresponsedata,informcustomerstotransactbusinessthroughthekeytowherethewindow,thenthenexttimetheticketdispensingmachinesreadytotakeanumber,thewholeprocessisveryfast.Foramorepersonalizedservicetocustomers,companiescanalsosettheseat,andproviderelevantbusinesspresentationnewspapers,books,placingthecompany.Increasecustomerwaitingtimefunatthesametime,itcanalsoallowcustomerstomorein-depthunderstandingofthecompany'sbusinessprocesssense.Thisprocesseffectivelyavoidaseriesofproblemscausedbycongestion,improveworkefficiency.Thesis,theimplementationmethodqueuingsystem,theresultshaveimportantguidingsignificanceforreality.Theresultsconfirmedthepossibilityofcompletesingle-chipqueuingsystem.Featureofthispaperistheuseofplainlanguage,tointroduceaqueuingsystemprinciplesanddesignideas,hassomeimpactondailyproductionandlife.Keywords:protuesqueuingmicrocontrollerhuma目录第1章绪论...................................................................................................................................12.1系统的基本功能和工作原理...........................................................................................22.1.1基本功能.................................................................................................................22.1.2工作原理........................................................................................................................22.2排队系统工作流程...........................................................................................................22.3系统整体设计...................................................................................................................22.3.1硬件概要设计.........................................................................................................22.3.2软件概要设计.........................................................................................................3第3章主要硬件参数...................................................................................................................43.1STC89C52RC单片机........................................................................................................43.1.1单片机的CPU结构................................................................................................43.1.2STC89C52RC引脚功能说明..................................................................................43.1.3单片机的存储器......................................................................................................63.1.4单片机最小系统设计..............................................................................................73.2液晶显示器.......................................................................................................................83.2.1液晶显示器的原理及分类......................................................................................83.2.2LCD1602液晶.........................................................................................................93.2.31602液晶模块的读写操作...................................................................................10第4章系统流程图.....................................................................................................................11第5章系统电路及仿真结果.....................................................................................................125.1晶振电路..........................................................................................................................125.2开关电路..........................................................................................................................125.3LCD1602电路.................................................................................................................135.4蜂鸣器电路
