基于Zig Bee无线传感器网络网关的设计与实现

摘要

给出了基于ZigBee的无线传感器网络(WSNs)网关节点的软硬件设计与实现方案.网关节点以ARM9嵌入式处理器ARM966E-S为核心,uC/OS-Ⅱ为嵌入式实时操作系统,配以内置TCP/IP协议的GPRS模块作为网络数据出口和CC2420无线收发模块.实验结果表明:网关节点工作可靠,能够较好地满足低功耗和实时性的要求.%Design and realization scheme of sink node in Zig Bee wireless sensor networks is proposed. The embedded CPU ARM966E-S is the core of sink node,which has the uC/OS-II embedded operation system, the interface of GPRS model with TCP/IP and wireless transfer model CC2420. Experiment results show that the gateway works well. The needs of the lowpower and real-time can be met.
