基于ZigBee技术的无线传感器网络网关设计与实现

摘要

With the further development of wireless network technology,the advantages of wireless sensor networks (WSN) are further reflected than others.WSN will replace most even all of wired sensor networks.In wireless sensor networks,the gateway plays an important role.In this article,beginning with the advantages of ZigBee technology,WSN gateway program based on ZigBee protocol stack is analyzed in detail.In addition,the hardware and software system are designed from the program.Finally,WSN gateway is realized with the use of IC of Microchip.The results show that the gateway can realize the aims at accurate data transmission and stable performance.And the need of the low-cost,low-power and strong anti-interference ability also can be well meet.%随着无线网络技术的深入发展,其优势进一步地体现出来,无线传感器网络将大量甚至全面替代有线传感器网络.在整个无线传感器网络中,网关起到了至关重要的作用.本文从无线传输网络的ZigBee技术优势入手,深入分析基于ZigBee协议栈的无线传感器网络网关方案,进行硬件及软件系统设计,最终利用微芯公司的芯片制作成无线传感器网关.实验结果表明,所设计的网关传输数据准确、性能稳定,并且较好地满足低成本、低功耗、传输距离远的要求.
