摘　　要：对无线传感器网络节点进行了研究,提出2.4GHz、433MHz双频传感器节点的硬件结构设计。双频无线传感器节点既可工作于2.4GHz基于ZigBee协议进行短距离、低功耗通讯,也可工作于433MHz利用射频功放电路进行远距离通讯,可按不同的无线通讯协议和网络体系结构来构建无线传感器网络,为该领域的研究提供了优异的实验平台。The wireless sensor network node is first analyzed, a hardware structure design of the double frequency wireless sensor network node based on 2.4GHz and 433MHz is proposed. The wireless sensor node based on this design idea can be used to build wireless sensor network by multiple communication protocol and network architecture. It can communicate with each other either in a short dis- tance and low power consumption at 2.4GHz based on ZigBee communication protocol or in a long distance based on 433MHz by wireless power amplifier. It is also a powerful experimental platform for the research in this domain.
