基于ZigBee的持续高波特率无线通讯方法研究

A solution study on durative high baud rate wireless transfer based on ZigBee technology

ZigBee无线通讯技术因其低复杂度、低功耗、低成本等优点在中小型网络中的应用日渐广泛,然而目前对其数据传输的应用基本都是少量、短时性质,对其持续高波特率数据传输等方面的应用并不多。针对ZigBee的持续大量数据传输的可靠性问题,对在9 600 bps^115 200 bps波特率下的基于ZigBee的长时间、大数据量无线通讯进行了尝试和研究;针对数据传输的正确性问题设计了通讯协议和校验方案,进行了误码率测试实验,并给出了实验数据。实验结果证实了ZigBee在持续高波特率传输上的可行性和可靠性。

Applications in small networks based on the ZigBee technology have been keeping growing because of ZigBee＇s merits such as low complexity,low cost,and low power.But these applications are mostly based on small quantity and short-term,not on data transfer under durative high baud rate.Aiming at validating the reliability of durative mass data transfer,an attempt and research were made on long-playing communication carries mass data based on ZigBee technology under the baud rate range from 9 600 bps to 115 200 bps.An experiment was made to figure out the bit error rate under different baud rate and the design of communication protocol and verify method contrapose the correctness of data transfer.Some meaningful experimental data were given.The results indicate the feasibility and reliability of durative high baud rate wireless transfer based on ZigBee.
