病床呼叫管理系统I本科毕业论文(20届)病床呼叫管理系统的设计与实现所在学院专业班级计算机科学与技术学生姓名指导教师完成日期轩友会车友综合信息管理系统II摘要在如今的各大医院中,特别是住院部的病房,都面临着医护人员人手不足的问题。医院无法为每一位病人安排一位医生,而病人的需要却是不定时的,这样很有可能延误病人的病情,出现医疗事故。病床呼叫管理系统就是为了缓解这种情况而出现的。本系统可以按照病人的病情紧急情况对病人的呼叫信息进行排列,通过动态优先级算法的分配,对病情比较严重的病人进行优先救治。首先,在论文中对现有的病房呼叫系统及其发展进行了描述,对其功能进行了分析、理解,为本系统做了充分的准备。而后,在此基础上,对本系统进行了需求分析,增加和完善了系统的功能,并且对系统实现所使用到的环境,技术和工具进行了说明。在需求分析的工作完成之后,对系统进行了总体设计,同时开发了本系统的数据库。本系统共分为两个客户端,分别为护士站端和病人端。一个护士站端应对应多个病人端,病人端可向护士站端发出呼叫请求,由护士站端派出护士进行处理,经过双方的三次确认完成整个的呼叫过程。最后,在系统的实现中,做到了集呼叫护士、替换护士、调派护士、统计工作量、视频通话为一体的病床呼叫管理系统。在系统中,使用了Visio建模工具建立系统功能分解图、活动图和流程图等,使用VisualStudio2005软件,通过C#语言完成了系统的界面设计。在.NET平台下,使用C/S结构完成了本系统。在最后经过了测试,证明本系统达到了系统设计时所提出的要求。关键词:C#编程;Socket通信;病房呼叫管理;动态优先级哈尔滨工程大学学士学位论文IIABSTRACTThelackofmedicalpersonnelhaslongbeenaprobleminmosthospitals,especiallyinwards.Allpatientscannotgetaone-on-onecarefromthedoctorswhiletheirneedsareofvariableinterval,which,mayleadtodelaytreatmentorevenmalpractice.Hospitalintercomsystemisdesignedtoeasethissituation.Thesystemisabletoarrangecallsfromthepatientsbytheseverityoftheillnesswithanalgorithmofdynamicpriority,givingprioritytotheseverecase.Thisdissertationgivesadescriptionandanalysistotheexistinghospitalintercomsystem,tohelpbetterpreparementforthisdissertation.Afterthat,requirementanalysisandillustrationaremadetohelpconsummatesfunctionandexplainthesoftwareenvironment,techniqueandtoolsneeded.Moreover,systemdesignismadeanddatabaseisaddedtoit.Thesystemincludestheterminalofnursestationandtheterminalofpatient,aone-to-manydependency.Patientsplacecallstothenursestationandnursesaresentinreturn.Thecallingprocessisfinishedbythreetimesofhandshakeprotocol.Finally,thehospitalintercomsystemisachievedwithfunctionsofcalling,dispatchingandreplacingnurses,workloadaccountandvideocalls.Inthissystem,Visioisusedtobuildsystemfunctionaldecompositiondiagram,activitydiagramandflowchart.InterfacedesignismadebyVisualStudio2005inC#.Systemdesignmentisfinishedon.NETplatformwithastructureofClient/Server.Theexpectedrequirementsaremeetandconfirmedbythefinalexamination.Keywords:C#Programming;Socket;HospitalIntercomSystem;DynamicPriority病床呼叫管理系统III目录第1章绪论..............................................................................................................................11.1课题背景及目的...........................................................................................................11.1.1课题背景............................................................................................................11.1.2课题目的及意义................................................................................................11.2病床呼叫管理系统的现状与发展..............................................................................21.2.1现有病床呼叫管理系统....................................................................................21.2.2病床呼叫系统的发展........................................................................................31.3内容和作者的主要工作...............................................................................................31.3.1论文主要内容....................................................................................................31.3.2作者的主要工作................................................................................................41.4论文的组织结构...........................................................................................................4第2章系统需求分析..............................................................................................................52.1系统开发平台和语言...................................................................................................52.1.1系统的开发平台................................................................................................52.1.2系统的开发语言................................................................................................62.1.2数据库连接简介................................................................................................62.2系统需求分析..............................................................................................................72.2.1系统的目标........................................................................................................72.2.2系统的总体任务................................................................................................82.2.3系统功能需求....................................................................................................82.2.4系统用例分析..................................................................................................102.3本章小结....................................................................................................................12第3章系统的详细设计........................................................................................................133.1总体设计.....................................................................................................................133.1.1系统的设计准则............................................................................................133.1.2系统开发模式.............................................................
