沈阳理工大学学士学位论文PAGE\*MERGEFORMATV摘要病床呼叫系统是现在国内医院中需求很高的一种应用电子设备，具有相当大的社会意义和重要的实用价值。所使用的病床呼叫系统既要考虑到医院的整体环境，又要有很好的实用性以及装饰性。它为病人和医护人员之间搭建起一个信息沟通的快速通道，使病房病人在紧要时可得到及时的治疗。本文论述了一种病床呼叫系统的设计方案和实现方法。系统使用VHDL语言，采用目前比较流行的FPGA来完成病房患者呼叫器与护士所在护士站主控之间的通信。文中给出了该系统的软件设计与仿真结果。本系统底层模块采用文本设计输入方法，编译，仿真，生成相应的模块元器件；顶层模块采用原理图设计输入方法，将底层模块元器件结合简单门电路连线而成；最后对系统进行了整体仿真测试。结果表明，系统各功能模块工作状态良好，整个系统设计达到了预期的目的。本系统具有结构简单，程序调试容易，可靠性高，功耗低，安装方便等特点，具有很强的实用价值。关键词：病床呼叫；VHDL；FPGA；底层模块AbstractElectronicdevicethatwidelyusedinmanyhospitalsforthesystemofhospitalbedcalling,becomemoreandmorepopularandvaluable.Thesystemshouldconsiderbothvaluableanddecorativeaswellasthewholedesignofthehospitalrequirements.Itisbuildinganinformationchannelthatcouldconnectwithbothpatientsandhealthcareworkers,soitmaybeverybeneficialforpatientstohavetheeffectivetreatmentsinashorttime.Thispaperdiscussedtheconcretedesignandthemethodofrealizationonthesystemofhospitalbedcalling.Inthesystemdesigned,FPGAthatisverypopularnowadaysusingVHDLwasadoptedtohelpthepatientsinhospitalbedcommunicatewithnursesinthenursesstation.Thesoftwaredesignandthesimulationresultsofthesystemarepresentedinthisthesis.Thebuttonmodulesofthesystemwasdesignedbythemethodoftextdesigninput,compiled,simulatedandthengeneratedthecorrespondingcomponentofthemodule;Themethodofschematicdiagramdesigninputwasadoptedtodesignthetopmodule,inwhichthecomponentsofthebuttonmodulescombinedandlinkedwithsomesimplegates;Finally,thesystemwastestedasawhile.Onasummaryofallthework,allofthemodulesworkedwellandthewholesystemattainedthedesiredgoals.Thesystemischaracteredbysimplestructure,easyprogramdebugging,highreliability,lowpowerconsumptionandeasyinstallation,whichmakeitpossesspracticalvalue.Keywords:hospitalbedcalling;FPGA;VHDL;buttonmodules目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc422426892"1绪论PAGEREF_Toc422426892\h1HYPERLINK\l"_Toc422426893"1.1课题背景和意义PAGEREF_Toc422426893\h1HYPERLINK\l"_Toc422426894"1.2国内外研究现状PAGEREF_Toc422426894\h1HYPERLINK\l"_Toc422426895
