摘　　要：主要介绍了当前在智能仪器设计中广泛应用的USB通信技术,重点介绍和分析了USB通信系统软件结构和枚举过程,能有效的帮助技术人员在没有USB总线分析仪等昂贵的硬件设备的情况快速调试USB通信。并将该技术用于智能化心血管功能检测仪的设计中,已可靠地实现了与计算机之间的USB通信功能,显著提升了智能仪器的通信性能,具有良好的推广应用价值。This paper introduces to USB communication, which is used widely in the intelligent apparatus. And emphasize and analysis software structure, and course of enumeration. It is helpful to technicians to rapidly debug USB communication without such as USB bus snooping instrument. It has been used in system of intelligent detection on cardiovascular function, and come true the USB communication between PC and apparatus. This technique improves clearly the communication performance of intelligent apparatus, and can be spread.
