商丘学院本科毕业设计摘要为使医疗人员实现更好、更便捷和病人之间的沟通，提升了医院服务水平和质量，本文主要以AT89S51为核心的病房呼叫系统，该系统主要由蜂鸣器，数码管，指示灯，按键及单片机组成。当病房的病人需要帮助时，可以按下呼叫的按钮，值班室的值班人员可在显示器上看到相对应的房号和床号，然后再安排并落实病人的需求。如果有多人同时的按下按钮的时候，可以按照实际的情况来安排，尽量先解决重病房的病人需求。另外该系统采用的是有线的，优点是安全可靠，不干扰其它医疗电子设备的正常运行，缺点是安装的时候繁琐，设备的维护不方便，时效性也比较低。关键词：病房呼叫;单片机;串口显示I商丘学院本科毕业设计AbstractTorealizebetterandmoreconvenientmedicalstaffandpatientstocommunicatebetween,improvethelevelandqualityofserviceinhospital,thisarticlewhonastywardcallingsystemwithAT89S51asthecore,thesystemismainlycomposedofabuzzer,digitaltube,lights,buttonsandsinglechipmicrocomputer.Whenwardpatientsneedhelp,youcanpressthecallbutton,thedutyroomattendantscanbeseenonthedisplaynumbercorrespondingtotheroomandbed,andthenarrangeandimplementthepatient'sneeds.Iftherearemanypeopleatthesametime,pressthebutton,canaccordingtotheactualsituationtoarrange,asfaraspossibletosolvetheheavywardpatientsneeds.Inaddition,thesystemUSESacable,theadvantageissafeandreliable,doesnotinterferewiththenormaloperationofothermedicalelectronicequipment,thedisadvantageisthatwheninstallingtrival,equipmentmaintenanceisnotconvenient,timelinessisalsolow.Keywords:wardcall;Singlechipmicrocomputer;serialportdisplayII商丘学院本科毕业设计目录1绪论....................................................................................................................................12系统硬件设计....................................................................................................................12.1单片机介绍............................................................................................................12.2系统原理................................................................................................................22.3主要元器件介绍....................................................................................................22.4各模块设计............................................................................................................42.4.1LED显示模块设计....................................................................................42.4.2键盘模块设计............................................................................................42.4.3声音模块设计............................................................................................42.4.4接口电路设计............................................................................................42.5单片机控制电路....................................................................................................53系统软件设计....................................................................................................................53.1系统总流程图........................................................................................................53.2各模块功能设计....................................................................................................63.3系统平台................................................................................................................93.3.1汇编语言.....................................
