机场物联网融合网关的设计与实现

Design and Implementation of Airport IOT Integration Gateway

机场飞行区中存在多种类型测控设备,这些设备有着不同类型的无线通信协议。因不同协议的设备缺乏管理且存在物联网入网需求,设计异构网络融合的机场物联网网关有其重大价值和现实意义。文章设计的网关选用RK3399为核心处理器,搭载了BLE、Wi-Fi和LoRa模块作为南向接口的汇聚节点,网关北向接口支持5G和Ethernet方式进行双向通信。文章所设计的物联网网关实现了LoRa、BLE和Wi-Fi机场物联设备的接入、南向接口与北向接口数据的协议转换、本地化数据实时存储和远程运维管理,支持至少200个设备的接入和800Mb/s的上下行速率,并针对机场海量设备和数据的传输场景提出了自适应数据传输机制。所设计的网关借助阿里云平台进行示范验证,验证了其有效性与可靠性。

There are many types of measurement and control equipment in Aerodrome Traffic Zone, which have different types of wireless communication protocols. Devices with various protocols need proper management and network access. Therefore, it is of great value and practical significance to develop an airport IOT gateway that can realize the integration of heterogeneous networks. The designed gateway selects RK3399 as the CPU and is equipped with BLE, Wi-Fi and LoRa modules as the sink node in the southbound network. It supports the two-way communication of northbound data through 5 G and Ethernet. This design finally realizes the access of airport IOT devices of LoRa, BLE and Wi-Fi, protocol conversion of data in South and North interfaces, real-time storage of localized data and remote operation and maintenance management, supports the access of more than 200 devices and the uplink and downlink rate of 800 Mbps, and puts forward an adaptive data transmission mechanism for the airport transmission scenario with massive equipments and data. The gateway designed in this paper has been verified via Alibaba cloud platform for its effectiveness and reliability.
