摘要
ZigBee和WiFi是智能家居设备常用的两种无线通信技术,针对智能家居设备使用ZigBee自组网无法和用户WiFi网络中的智能终端直接通信的问题,设计面向家庭应用环境的ZigBee-WiFi无线网关.网关采用S3C6410作为控制核心,运行Linux操作系统,以USB连接无线网卡,以DMA通道连接CC2530模块.通过信道扫描切换的方案解决ZigBee和WiFi两种信号之间相互干扰的问题,通过数据线连接的方式给要加入ZigBee网络的新设备分发密钥.实验表明,所实现的无线网关信号稳定,丢包率低,实用性强,在智能家居系统中运行稳定、可靠.
In smart home applications, ZigBee and WiFi devices are two common wireless communication technologies. The problem is that the smart home devices in the ZigBee self-organizing networks can not directly communicate with the intelligent terminals in the WiFi networks. In order to solve this problem, a home-oriented application environment ZigBee-WiFi wireless gateway is designed. The gateway uses S3C6410 as the control core, runs on the Linux operating system, connects to a wireless network card with USB and connects CC2530 module with the DMA channel, which resolves the issue of mutual interference between ZigBee and WiFi signals by scanning and switching the transmission channels. Key is distributed to the new devices that join the ZigBee network by mini USB connections. Experiments show that the wireless gateway has stable signal and less packet loss. It is stable and reliable in application of smart home system.
