摘要
将Zigbee无线传感网络与嵌入式处理器、嵌入式操作系统相结合,构建一个家庭网关。以RT5350为主控芯片,使用多块CC2530开发板组建一个Zigbee网络,实现一个完整的家庭网关。在RT5350处理器中植入嵌入式Linux操作系统,移植Web服务器Boa和嵌入式数据库SQLite。Zigbee终端节点获取到传感器数据,通过Zigbee无线网络传输给Zigbee协调器,Zigbee协调器通过串口发送给处理器,采集的数据保存在SQLite嵌入式数据库中。局域网客户端可以通过连接WIFI监控实时数据,远程用户可以通过连接Internet查看实时数据,实现了Zigbee、以太网和WIFI的互通互联。
A home gateway is formed by combining a Zigbee wireless sensor network with embedded processor and embedded operating system.By using RT5350 as the main MCU and using several CC2530 boards to form a Zigbee network, a complete home gateway is implemented. An embedded Linux operating system is implanted into the RT5350, the Web server Boa and embedded database SQLite are transplanted.The Zigbee end devices get the collected data from the sensors ,then send it to the coordinator through the Zigbee wireless sensor network. The coordinator transmits the data to the processor via serial port, and the data is stored in the embedded database SQLite.The clients can monitor the real-time data by connecting to the WIFI, meanwhile the remote users can check the real-time data by connecting to the Internet,realizing the interconnection of Zigbee,Ethernet and WIFI.
