摘　　要：介绍了LabVIEW 7 Express开发环境下数据采集与信号处理的实现方式。以计算机和USB2002数据采集卡为主要硬件,LabVIEW为软件开发平台,构建了用于实现信号的采集与信号分析的多功能虚拟仪器系统。系统可实现单通道、多通道数据的采集,信号分析,以及数据的存储和对历史数据的复现。在降低设备成本的同时,该系统还具有友好的人机界面,并且方便进行维护和实现功能扩充。该系统已应用在电力系统试验中,充分体现了方便、快捷、实用等诸多优势。The realizing methods of the data acquisition and signal analysis was introduced based on LabVIEW 7 Expreas. It set up a virtual instrumentation with the function of data acquisition and signal analysis, based on computer and USB2002 data acquisition card and software of LabVIEW. The system includes the signal acquisition and control module which can realize the data acquisition with single channel or multi-channels as well as memory and signal recall. Reducing the cost of the equipment, the system can also provide a friendly human-machine interface. In addition, it is convenient for the system maintenance and function expansion. It is also convenient to the system maintenance and function expansion. The system has good verification and shows the superior performances in the power system.
