Windows环境下生物医学信号高速采样的实现

High Speed Biomedical Data Sampling Technique Based on Windows

Windows下的实时数据采集是生物医学信号处理中很重要的一部分 ,然而Windows操作系统为非实时系统。本文介绍了在非实时的Windows下进行实时数据采集的几种常用方法 ,同时给出了利用Windows本身实现高速采样控制的两种方法。综合使用本文提出的方法 ,可在Windows环境下实现 5 0kb s的实时采样 。

Real\|time data collection under Windows environment is a very important part for bio\|medical signal processing.However,Windows Operating System is a non\|real\|time system.In this paper,several commonly used methods for real\|time data collection under non\|real\|time Windows environment are introduced. At the same time,two methods for high speed sampling control,using Windows Operating System itself,are given.Comprehensively using the methods proposed in this paper,real\|time data sampling of 50kb/s can be carried out to implement collection of electric\|physiological data.
