基于单片机的病房呼叫系统VIP免费

毕业设计题目基于单片机的病房呼叫系统姓名雷顺頔学号20126005系部理工系年级专业2012级电子信息工程指导教师陈亚妮2016年3月5日摘要呼叫系统是医院和养老院的必备设备，是日常护理和紧急抢救重要通讯手段。传统有线呼叫系统施工繁琐、检修困难、施工成本高，更重要的是有线系统没有移动接收呼叫信息的功能，使很多病人丧失了抢救的良机。随着医院、养老院的医疗条件的不断提高，越来越多的场所采用无线呼叫系统，施工和维护简便，呼叫操作简单，医护人员可随时随地接收病人的呼叫。医护呼叫系统采用调幅（FSK）技术，保证呼叫成功率，避免信号干扰。根据医院和养老院的功能要求、场地大小、管理要求等因素，多种解决方案以供选择。关键词：单片机STC89C51，无线传输模块，病床呼叫Title：WardcallingsystembasedonsinglechipmicrocomputerAbstract：Callsystemisnecessaryequipmentinhospitalsandnursinghomes,isthedailycareandemergencyrescueofanimportantmeansofcommunication.Thetraditionalwiredcallsystemandfussyconstruction,maintenancedifficulties,highconstructioncost,moreimportantisthecablesystemisnotmobilereceivesthecallinformation,makemanypatientslosttheopportunitytosave.Alongwiththehospital,nursinghomemedicalconditionscontinuetoimprove,moreandmoreplacesusingwirelesscallsystem,constructionandeasymaintenance,operationsimplecall,callmedicalpersonnelcanwheneverandwhereverpossibletoreceivepatients.Addfastwirelessmedicalcallsystemusingamplitudemodulation(FSK)technology,ensurethecallsuccessrate,toavoidinterference.Accordingtothehospitalsandnursinghomes,thesizeofthesitefunctionalrequirements,managementrequirementsandotherfactors,plusXunseriesproductsprovideavarietyofsolutionstochoosefrom.Keywords:singlechipSTC89C51,wirelesstransmissionmodule,SickbedCallingII目录1绪论................................................................................................................................31.1病床系统背景与意义......................................................................................................31.2目标..................................................................................................................................31.3可行性分析......................................................................................................................31.4设计步骤..........................................................................................................................32基于单片机的病床呼叫系统的设计实现......................................................................42.1系统总体设计................................................................................................................43系统硬件设计...................................................................................................................73.1单片机介绍......................................................................................................................73.1.1单片机的发展介绍....................................................................................73.1.2单片机的结构特点....................................................................................73.1.3单片机的实际应用..................................................................................................73.1.4控制器AT89C51.......................................................................................83.2系统原理框图.........................................................................................................
