摘　　要：计算机对信号进行分析和处理依赖于数据的采集,而现有的数据采集卡成本高,接口复杂,不易扩展。采用USB控制器和FPGA为核心设计系统的硬件平台,再结合LabVIEW设计用户应用程序、NI-VISA开发USB驱动程序,最终实现高速数据采集系统的设计。实验结果表明,系统集成度高,结构灵活便于扩展,达到了30Mbit/s的可靠数据传输速度。Relying on the data acquisition, computer conducts signal analysis and processing. While the existing data acquisition card is high cost, interface complex, and hard to expand. Using a hardware platform which regards USB controller and FPGA design as the core of the system, combining the user application program designed by LabVIEW and USB driver by NI-VISA, the design of high speed data acquisition system is realized at last. According to the test result, the system with high integration, flexible structure which is easily expanding, reaches a reliable transmission speed of 30 Mbit/s.
