摘　　要：在雷达和声纳系统中,往往需要专用的数据传输接口实现主控中心和数据处理系统的实时可靠数据交互。而通用串行总线以其高数据传输率、无需配置、真正的即插即用等特性获得了广泛的应用,完全满足这种传输接口的要求。本文设计了一种基于EZ-USBFX2LP的高速数据传输接口,给出了完整的软硬件设计方案,包括硬件电路设计、固件程序和驱动程序以及应用程序的编写。该传输接口已成功运用到声纳系统中,其可靠数据传输速率达到了90Mb/s。实践表明,该接口设计稳定可靠,具有良好的移植性。An interface used to transfer data between control center and digital processing system is required in Radar and Sonar systems. The USB which has high-speed streaming data and can plug and play meets the requirement of the interface. A high-speed streaming data system based on EZ-USB FX2LP is designed in this paper. Design scheme including hardware circuit, firmware of MCU, driver and application programs of host is presented. This design has been used in Sonar which shows that this design works stably and can reach high-speed streaming data of 90 Mb/s.
