摘要随着社会的发展和人们生活水平的提高，人们对生活的健康质量也追求越来越高，为了方便老年人吃药，结合当前智能药盒蓬勃的发展状况，本文介绍了一种基于单片机的家庭用智能药盒的设计。首先，本文介绍了此系统所涉及的硬件的结构和工作原理，主要包括STC90C51单片机、LCD1602液晶和单片机的定时/计数器。其次，介绍了系统硬件的模块化设计和软件的编程思想。最后是对系统进行调试之后得出最后的结果。在第一部分着重介绍了单片机的各项参数、内部结构、引脚功能，LCD1602的硬件电路、显示原理和各项命令，定时/计数器和蜂鸣器原理的简单介绍。在第二部分则系统地介绍了各模块之间的运作模式和工作流程。最后调试完善后得到的系统运行基本模式为：系统基于单片机控制，通过对单片机STC90C516定时器中断的设计，使其完成对时钟运行的控制，并通过LCD1602液晶显示出来。当系统检测到有时间设置功能键或用药设置功能键有输入时，进入关中断调时及设置状态，之后开中断并按下定时键记录当前设置的时间及用药量的值。在调节好系统时间之后，系统时间向前运行的过程中不断将系统实时时间与记录时间作比较，两者相等时发出警报并显示所设置的用药量，一分钟后系统实时时间与记录时间不在相等则自动退出提醒，如此实现每天四次用药及每次四种用药服用量的提醒，比较适合普通家庭使用。关键词：智能药盒；STC90C516；时钟；1602显示AbstractWiththedevelopmentofsocietyandpeople'slivingstandardsimprove,moreandmorepeoplepursueahigherlevelofhealth.Inordertofacilitatetheoldtotakemedicine,incombinationwiththevigorousdevelopmentsituationofsmartpillbox,thispaperintroducesadesignofdomesticsmartpillboxbasedonSTC90C516SCM(Singlechipmicrocomputer).First,thispaperintroducesthesystemstructureandworkingprincipleofhardwareinvolved,mainlyincludesSCM,LCD1602andthecountertimeroftheSCM.Secondly,thepaperintroducesthesystemhardwaremodulardesignandsoftprogrammingideas.Finally,getthefinalresultafterdebugging.ThefirstpartintroducesthevariousparametersofSCM,theinternalstructureandpinfunctions,aswellashardwarecircuitandvariouscommandsofLCD1602,theprincipleofLCD1602,countertimerandbuzzer.Thesecondpartintroducestheoperationmodelandworkprocessbetweeneachmodulesystematically.Afterthecompletionofdebugging,thesystembasicoperationmodeis:thesystemisbasedonSTC90C516,throughthedesignofSTC90516timerinterrupt,thesystemcontroltheclockrunningforward,anddisplaythetimeontheLCD1602.Whenthesystemdetectsthatthetimesettingkeysorthedosagekeyshaveinput,closetheinterruptandsettingthevalueoftimeordosage,thenopentheinterruptandpressthetime-settingkeysdowntorecordthetimeanddosage,Asthesystemtimerunningforward,comparingrecordtimewiththecurrenttime,whentwovaluesareequalactivatethealarmanddisplaythedosagevalue,aminutelatter,thetwovaluesarenotequal,thesystemclosethealarm,thisisthewayofremindingapersontotakefourkindsofmedicinefourtimesadayit`ssuitableforordinaryfamilies.Keywords:smartpillboxSTC90C516clockLCD1602目录摘要......................................................................IAbstract.................................................................II1绪论....................................................................11.1选题目的和意义.....................................................11.2目前智能药盒的现状.................................................11.3本文的结构.........................................................22系统总体方案设计........................................................32.1设计要求...........................................................32.2总体设计思路.........................................
