摘　　要：介绍一种基于USB总线的中医脉象采集系统的软件设计与实现方法。该软件包括设备固件、设备驱动程序、动态链接库和用户程序。设备驱动程序的数据传输部分采用数据块分解传输方法,支持用户自定义大小的I/O请求,为用户程序提供更加灵活的设计方法。用户程序最终在LabWindows/CVI平台上开发成功,实际运行表明,该软件设计满足脉象采集系统的要求。A software design method of acquisition system for sphygmus information based on USB1.1 is provided. It consists of four parts： firmware, device driver, dynamic link library and user application. Device driver supports user-defined size of I/O request by its disassembly I/O request technology, so the user application can be designed more flexibly. The user application is developed on platform of LabWindows/CVI. The system is tested with lots of practice which proves the software design meets the demand of acquisition system for sphygmus information.
