【摘要】 目前中医脉象信号采集系统是以ISA或PCI总线的扩展卡形式实现采集功能 ,在可靠性、扩展性等方面尚有不足。通用串行总线 (USB)为数据采集提供很大的便利 ,利用USB可实现较传统方式更有效、更经济的数据采集。该文介绍用USB接口实现中医脉象信号的数据采集系统的硬件和软件设计更多还原

【Abstract】 Expansion cards based on ISA or PCI Bus are widely used to realize the data acquisition of the human pulse signal,but there are some drawbacks in the reliability,stability and so on.It is the Universal Series Bus(USB) that provides much convenience to the data acquisition.Applying the USB technology to the data acquistion will be more efficient and economical. This paper introduces how to use the USB to realize the data acquisition of human pulse signal.更多还原
