呼吸参数虚拟测量系统的设计

本文介绍了一种基于虚拟仪器的呼吸参数测量系统，该系统由硬件和软件两部分组成。硬件主要采用传感器、调理电路、数据采集和通用计算机，软件采用Lab VIEW编程，由于有大量成熟的软件模块，大大提高了开发效率。经扩展可用于其他生理数据的采集和处理。

Design of a Virtual Test System of Breath Parameters

The development of a test system of breath parameters based on virtual instrument is introduced in this paper. The system is consisted of the hardware and the software. The hardware includes the sensor, the measuring circuit, A/D card and the computer, and it used LabVIEW software platform, which provides a lot of modules to make the programming efficient. It can be adapted to other physiological signals acquisition and processing system with the expanded function.
