摘要
生理信号采集是对生理信号分析和处理的首要环节。介绍了PC/ 10 4系统的常用开发模式 ,给出了基于PC/ 10 4的多道生理信号采集系统的设计方案。系统硬件主要包括PC/ 10 4嵌入式计算机、DIAMOND -MM- 16 -AT集成采集卡和四通道生理信号放大器。用Windows 2 0 0 0作为PC/ 10 4嵌入式计算机的操作系统 ,用VisualC+ + 6 .0编写了多线程数据采集程序。实验结果表明 ,基于PC/ 10 4的生理信号采集系统能够实现多道生理信号的采集、处理和实时显示 ,并且具有体积小、功耗低、结构牢固。
The acquisition of physiological signals is the first step of its analysis and processing. The development mode for PC/104 module is introduced and the design of multichannel acquisition system for physiological signals based on PC/104 is also put forward. The system hardware mainly includes PC/104 embedded computer,DIAMOND-MM-16-AT acquisition card and four-channel amplifiers. Windows 2000 is used as operating system for PC/104 embedded computer. The multithread program to sample data is made by means of programming language Visual C++ 6.0. The experimental results show that the system can be applied to sample, analyse, and process the physiological signals. The system also has lots of advantages, such as small volume, low power, firm structure and steady performance.
