摘　　要：多媒体声卡技术的发展,使得基于声卡的信号产生和数据采集成为可能。通过对振动测试系统的分析,提出了一套以计算机声卡作为激励源和采集模块组建振动教学实验系统的方案,阐述了计算机声卡的基本原理、软件结构,并对系统中的多声卡访问控制技术、共享多线程技术等关键问题进行了论述。It is possible that the signal generator and data acquisition based sound card with the development of the multimedia sound card technology. A scheme of the vibration measurement teaching and experiment system that generating signal and acquiring data using sound card is brought out through the analysis of vibration measurement system. Also, the paper sets forth the basic principle and the software architecture about sound card. In addition, several key technologies are discussed, access and control to multiple sound cards and shared multi-thread technology.
