| 摘 要： | 设计了一套基于LabVIEW的心电信号采集系统,实现心电信号实时在线采集。设计系统是由硬件部分和虚拟仪器VI两部分构成。硬件部分包括电极、心电图机、NI ELVIS、数据采集卡和计算机5个部分;虚拟仪器VI的前面板对应着一台实际仪器的面板,实现的是对仪表的控制和信号表达功能;程序框图是程序的图形化源代码,实现数据采集卡对信号的模/数转换,信号的分析显示。实验室测试表明,基于LabVIEW的心电信号采集系统能够实现心电信号的动态实时显示。

| Abstract: | ECG data acquisition system based on LabVIEW is designed to real display electrocardiogram.The system is composed of hardware and virtual instrument VI.Hardware is made up of electrodes,ECG machine,NI ELVIS,data acquisition card and computer.The front panel of VI is just as a real instrument panel,which can control instrument and express signals.Block diagram is a graphical source code of program,which can realize A/D conversion function by data acquisition card,and real-time analysis and display signal.Laboratory tests showed that ECG data acquisition system based on LabVIEW can display ECG waveform real and dynamically. |
