摘　　要：为了使物联网网关连接多个串口设备且能够并行处理来自串口的数据,设计了一个支持多路串口设备连接、在线配置串口参数的物联网网关。网关部署在Raspberry Pi开源硬件平台。软件基于开源的Kura框架,使用OSGi插件技术进行开发,功能模块将来自不同串口的数据按照不同的主题以消息的形式发送到云端,模块之间使用事件通信,网关与云端采用MQTT技术实现数据通信,Kura实现了串口的可视化配置。实际应用表明,该系统可以稳定、可靠地工作,达到了设计要求。In order to use the Internet of Things gateway to connect multiple serial devices,and to process data from the serial port in parallel,a gateway of the Internet of Things(IOT)with online configuration of serial port parameters is designed.The gateway is deployed on Raspberry Pi.The software based on the open source Kura framework adopts plug-in technology.Function modules send data from different serial ports to the cloud in the form of messages according to different topics.Events are used to communicate between modules.MQTT technology is adopted to realize gateway and cloud data communication.Kura realizes the visual configuration of serial ports.The practical application shows that the system can work stably and reliably,and meets the design requirements.
