智能家居无线传感器网络的研究

Research on wireless sensor network for smart home

为了克服传统有线网络的弊端,针对智能家居环境监测系统,设计了Zigbee无线传感器网络.以MSP430超低功耗处理器和最新的Zigbee CC2480芯片为核心,嵌入式实时操作系统为平台进行低功耗节点的设计.根据文中的低功耗设计措施,节点使用寿命可以达到3年半左右,整个系统运行稳定.最后,用Matlab7.0的Truetime工具箱验证了所设计的节点在节点数目较多的网络中能稳定运行.

With the increase of intelligence of smart home,more and more sensors are used in the smart home system.At the same time,the drawbacks of the wire network become evident.Zigbee wireless sensor network was designed for the environment monitoring of the smart home system in this paper.Low-power nodes were made by using the MSP430 ultra-low power processor.The latest Zigbee chip CC2480 was the core,and embedded real-time operating system was the platform.According to the low-power design,the node′s lifetime was about 3.5 years.At last,applying Truetime toolbox in Matlab7.0 proved that the node could work reliably in the large number node network environment.
