摘    要:作为计算机和网络技术与传统仪器融合的产物,虚拟仪器具有很多传统仪器无法比拟的优势.以NI公司的LabVIEW为开发平台,本文设计了一个低成本的虚拟心电信号采集系统.该系统摈弃了传统虚拟仪器的前端数据采集卡,而自行开发了以单片机技术为硬件基础的前端数据采集卡,从而有效地降低了成本;以LabVIEW8.2作为该系统仪器面板的软件编程语言,又可缩短开发时间.经实验室使用验证,该系统可实现对心电信号的实时采集、显示和存储,而且性能可靠,工作稳定,成本又大大地降低.

关 键 词:心电  单片机  信号采集系统  虚拟仪器

Abstract:As a fusion product of computer, network technique and traditional instrument, virtual instrument has many incomparable advantages over traditional instrument. Taking NI Company's LabVIEW as the development platform, an electrocardiogram (ECG) acquisition system was developed using virtual instrument technology at low cost. Microcontroller technology was selected as the hardware base to construct the data-acquisition board to replace traditional front-end data-acquisition card and LabVIEW 8.2 was used as th...
Keywords:electrocardiogram (ECG)  microcontroller  signal acquisition system  virtual instrument (VI)
