【摘要】 通用串行总线(USB)主要用于外部设备与主机之间的通信,尤其是外设与主机之间的高速数据传输。目前在工业控制领域中,数据的传输大都采用此种方式,但随着无线USB(WUSB)技术的不断发展和日益成熟,它也逐步广泛地被用于外设与主机之间的通信。本文即基于无线USB技术,成功实现了心电信号和脑电信号的无线采集与处理,此平台的构建将使WUSB技术在信号的采集及处理中得到广泛的应用。文中阐述了整个系统的工作原理、硬件构成和软件设计,重点突出了射频模块和数据的无线传输过程。更多还原

【Abstract】 Universal Serial Bus (USB) is used mostly for communications between external devices and the host, particularly highspeed data transmission between them. In the field of industrial control, data transmission usually uses this way. But with the wireless USB technology continues to grow and mature, it is also gradually used for data communication between the peripheral and the host. This system achieves the physiological signal acquisition and wireless transmission based on wireless USB technology, this platform will enable the WUSB technology to be widely used in the signal acquisition and processing. The article describes the working principle of the entire system、hardware and software design, focused on the RF module and the process of wireless data transceiver.更多还原
