摘要
分析了无线传感器网络节点的需求,阐述了无线传感器网络节点的体系结构.在此基础上采用符合802.15.4协议的ATmega128L主控和CC2420射频传输的设计模式,以模块为单位进行设计,分为处理器模块、无线通信模块、传感器模块、能量供应模块四部分,最后整体实现了该设计.通过对比本文设计节点与Micaz节点的数据包随距离变化的接收率测试结果和温度传感器数据采集测试结果,证明该设计取得了良好的效果,为无线传感器网络进一步的深入研究提供了一个性能较好的硬件平台.
The needs of a wireless sensor network node are analyzed with the architecture of the node described. According to the protocol 802.15.4, the design mode of the node consisting of the main controller ATmega128L and CC2420 RF transmission is adopted in modular form including the wireless communication, processor, sensor and power supply modules, thus implementing the design as a whole. Comparing the test results of data packets sending/receiving rates varying with the distance from the nodes thus designed with those from Micaz nodes and temperature data acquired by temperature sensor, the designed node shows a favorable effect and provides further a high performance hardware platform for in-depth study of wireless sensor networks.
