基于LabVIEW的脉搏检测系统设计摘要本课题以STC15单片机作为控制系统核心的心率测量仪的设计，先采用红外对管采集脉搏的信号，然后将LM328当做运放设计调理电路而处理所采集的信号，在其处理之后，将其送至单片机实施A/D采样与算法处理，其后在液晶屏上显示出脉率与脉搏波形。此外，应用LabVIEW进行上位机的设计而取得和MCU之间的通信。基本实现了对人体脉搏的测量，以及对脉搏波形的实时监控。此次脉率测量的设计方式较为简捷，并且具有精准的测试结果与整齐大方的显示界面，因此其发展前景是光明的关键词：脉搏检测系统，STC15W408AS，红外光电传感器，串口，LabVIEWDesignofpulseratedetectionsystem、AbstractThistopictoSTC15single-chipmicrocomputerascorecontrolsystemoftheheartratemeterdesign,byusinginfraredtubetopulsesignal,theamplificationfiltercircuitforfilterandamplificationprocessing,thepulsesignalsusingLM328asop-ampdesigncontrolcircuittorealizethecollectionofsignalprocessing,theprocessingofsignalintotheMCUA/Dsamplingandprocessingalgorithm,thefinalrealizationofpulsewaveformontheLCDpanelandpulsefrequencydisplay.Inaddition,LabVIEWisusedtodesigntheuppermachinetocommunicatewithMCU.Themeasurementofhumanpulseandthereal-timemonitoringofpulsewaveformarerealized.Thedesignmeasuringpulseratemethodissimple,thetestresultisaccurate,thedisplayinterfaceisfriendly,hastherelativelygooddevelopmentprospect.Keywords:Pulsedetectionsystem,STC15W408AS,infraredemissionreceivingsensor,serialport,LabVIEW目录1引言.......................................................................................................................................................11.1脉搏的研究背景...............................................................................................11.2选题意义...........................................................................................................12系统设计方案...........................................................................................................................12.1实现的要求和功能...........................................................................................12.2采集主控芯片方案..........................................................................................22.3脉搏传感器的选择...........................................................................................22.4上位机实现方案...............................................................................................43硬件电路设计...........................................................................................................................43.1系统总框架.....................................................................................................43.2单片机模块.......................................................................................................53.2.1主芯片STC15W408AS介绍.............................................................................53.2.2单片机最小系统模块....................................................................................63.2.3电源电路............................................................................................................63.2.4复位电路............................................................................................................73.3脉搏信号的采集...........................................................................................................73.4脉搏信号的处理.................................
