基于ZigBee网络的USB节点研究与实现

摘要

研究并实现了基于ZigBee网络的通用的串行USB接口节点,可以克服常规通信距离限制和布线麻烦等不足,扩大ZigBee技术的应用范围.由无线收发模块(CC2430)、USB接口(CH375)和电源等构成基于ZigBee网络的USB节点硬件.为USB接口定制并封装UVC和UAC协议,CC2430与CH375以异步UART模式串行通信,实现基于ZigBee网络无线收发信息功能,包括音频、视频和数据等信息.经过USB节点点与点的数据收发测试,USB主机方式下可以进行稳定可靠的无线收发传输.%In view of the general USB interface device are common,the research and realization of the USB node based on ZigBee can overcome disadvantages of wiring trouble and distance limitations of the conventional communication, to expand the scope of application of ZigBee technology. The USB node based on ZigBee consisted of CC2430,CH375 and power,etc. UVC and UAC protocol was customized and packaged in the USB interface, serial communication between CC2430 and CH375 in asynchronous UART model realize the function of wireless information transceiver based on ZigBee,including audio,video and data information. After some data transceiver testing between point and point of USB node, testing can be stable and reliable wireless transceiver transmission in USB - HOST mode.
