Labview is a graphical programming language and development environment, it is widely accepted by the industry, academia and research laboratory, is recognized as the standard of data acquisition and instrument control software. Labview as far as possible using the engineering and technical personnel are familiar with the terms, ICONS and concepts, is a development tool for the end user, enhances the engineering personnel's ability to build your own system of science and engineering, in order to realize instrument programming and data acquisition system provides a convenient way. The design system is based on the altai company's data acquisition card PCI - 8602 for the hardware platform, the data stored in real-time and efficiently. The experimental results show that the system can effectively complete the signal of real-time acquisition, storage, signal analysis and real-time graphic display function, at the same time the experimental results also show that the system has a simple programming, good versatility, high portability, simple interface design generous, easy to operate, etc.Keywords：Labview；data collection；PCI-8602第一章绪论1.1背景随着计算机技术和智能仪器仪表的深入发展，数据采集处理技术作为数字信号处理的前期工作之一，被广泛应用于军事、工业、通信、消费电子、医疗等测控领域。
