基于openHAB的嵌入式智能家居网关设计

为解决不同厂商生产的设备使用的协议不相同，设备兼容性差和网络异构等问题，提出基于openHAB （开放式家庭自动化总线）的智能网关设计. 网关采用树莓派3B和Linux操作系统作为嵌入式系统，实现了利 用中间件技术连接多种不同协议的智能家居设备的功能. 编写了家庭自动控制程序和多种终端的用户界面，通 过配置WiFi、蓝牙等功能组件使得系统支持多种协议和天气等服务，利用RRD数据库记录温湿度参数，采用 motion软件实现摄像头视频监控，使用openHAB云服务实现远程登录. 经测试，系统能有效支持多种协议，远 程登录、数据库和摄像头视频监控功能均正常.
