医院住院呼叫系统的设计与实现

毕业设计（论文）题目：医院住院呼叫系统的设计与实现系别：专业班级：姓名：学号：指导教师：职称：广西工学院鹿山学院本科生毕业设计（论文）I摘要随着科学与技术的发展，医院呼叫系统也成了医院的必须设备。为了丰富了医院呼叫系统的控制方式，使医生更加及时的了解病房动态及病人情况，同时也为了满足病人与护士取得实时联系，本论文采用了PLC可编程控制器为核心控制件，设计实现了新型PLC医院住院呼叫系统。所设计的PLC病床呼叫系统结构简单、易于管理、可靠性强，且可编程控制器病床呼叫系统可以及时、准确的实现病房呼叫管理，具有良好的应用前景。此系统应用于病人呼叫护士寻求帮助，护士根据护士站内显示器上的指示灯及响铃获取到求助信息的来源，并且及时的给病人提供帮助，提高了医院的工作效率，也更好地服务了病人，使医院医疗更科学化与人性化，在现实生活中具有举足轻重的作用。关键词：病床呼叫系统；PLC；S7-200广西工学院鹿山学院本科生毕业设计（论文）IIAbstractWiththedevelopmentofscienceandtechnology,thehospitalcallsystemhasbecomethenecessaryequipmentforthehospital.Inordertoenrichthecontrolofthehospitalcallsystem,allowingphysicianstomoretimelyunderstandingofwarddynamicandpatients,butalsotomeetthepatientsandnursestoobtaininrealtime,thepaperadoptsPLCprogrammablecontrollerasthecorecontrolparts,DesignandImplementationthenewPLChospitalcallsystem.PLCbedscallsystemstructureissimple,easytomanage,reliability,andprogrammablecontrollerbedscallsystemcanbetimely,accuratewardcallmanagement,andhasgoodapplicationprospects.Thissystemisappliedtothepatientnursecallforhelp,nurseaccordingtotheindicatorsonthemonitorinthenursesstationandringstogettothesourceofhelpinformation,andtimelyhelptothepatient,toimprovetheefficiencyofthehospital,butalsotobetterservethepatients,thehospitalmedicalscientificandhumane,hasapivotalroleinreallife.KeyWords:WardCallingSystem;PLC;S7-200广西工学院鹿山学院本科生毕业设计（论文）III目录1绪论.................................................................11.1选题的背景和意义...............................................11.2国内外研究现状和发展趋势.......................................11.2.1国外研究情况..............................................11.2.2国内研究情况..............................................21.3本文研究内容及安排.............................................22可编程序控制器的组成与工作原理.......................................42.1概述...........................................................42.2PLC的特点......................................................42.2.1使用灵活、通用性强........................................42.2.2编程简单、易于掌握........................................42.2.3可靠性高、能适应各种工业环境..............................42.2.4接口简单、维护方便........................................52.3采用PLC控制的优点.............................................52.4PLC的构成......................................................52.4.1CPU的构成................................................62.4.2存储器....................................................62.4.3输入/输出接口电路.........................................72.4.4电源.....................................................102.4.5扩展接口和通信接口.......................................102.4.6底板或机架...............................................102.4.7PLC系统的其它设备.......................................102.4.8PLC的通信联网...........................................112.5PLC的工作原理.................................................112.5.1扫描技术.................................................112.5.2输入采样阶段.............................................112.5.3用户程序执行阶段.........................................112.5.4输出刷新阶段.............................................122.6PLC的软件系统.................................................122.6.1监控程序.................................................122.6.2用户程序.................................................132.7PLC的编程语言.................................................132.7.1梯形图语言...............................................132.7.2指令表语言...............................................142.7.3状态转移图语言...........................................143医院住院呼叫系统的设计与实现........................................153.1任务描述......................................................153.1.1设计任务和要求...........................................163.1.2系统的工作流程...........................................163.1.3系统的运行环境...........................................183.2I/O接线图.....................................................213.3S7-200编程....................................................22广西工学院鹿山学院本科生毕业设计（论文）IV3.4梯形图程序设计................................................233.4.1主程序设计...............................................233.4.2子程序设计...............................................243.5系统说明......................................................244程序调试与仿真......................................................254.1程序的调试....................................................254.1.1程序的模拟调试...........................................254.1.2程序的现场调试...........................................254.2程序的仿真....................................................264.2.1准备工作.................................................264.2.2程序仿真.................................................264.3仿真结果........................................................29结束语.................................................................31致谢...................................................................32参考文献...............................................................33附录...................................................................34广西工学院鹿山学院本科生毕业设计（论文）11绪论1.1选题的背景和意义医院病床呼叫系统是一种应用于医院病房的专用呼叫系统，是医护人员和病人之间联系的重要桥梁。当病人需要医生帮助时，可以通过病床呼叫系统发出呼叫请求。当医生需要了解病人病情时，也可以通过病床呼叫系统来询问病人的状
