摘要
针对无线传感网络与Internet网络协议不兼容的问题,融合ZigBee与WIFI无线技术,设计了一款无线传感器网关,实现异构网络双向通信。基于德州仪器的MSP430作为处理器设计网关的软硬件,实现数据接收、信息处理、交互控制、无线协议转换等功能;使用ZigBee模块与无线终端节点相连,通过WIFI模块实现信息传输。通过家居环境测试,表明网关具有稳定性好、扩展灵活、使用便捷等特点,能满足智能系统无线网络的需求。
To solve the incompatibility between wireless sensor network and Internet networking protocol,a wireless sensor gateway is designed to achieve heterogeneous network's intercommunication,based on ZigBee and WiFi wireless technology.Texas instrument MSP430 is applied as the processor to design the hardware and software of gateway,aiming to achieve data reception,information processing,interactive control and wireless protocol conversion etc.The ZigBee module and wireless terminal node are connected to transfer information by WIFI module.The test was proved the stability,flexibility and convenience of the gateway in the home environment,and it can meet the needs of intelligent system wireless network.
