设计基于5G通信技术的船舶网络系统，以提升船舶航行过程中与地面控制站的连通性。该系统以B/S架构为基础，通过通信终端层中的船载终端通信装置，采集船舶航行相关数据后，连接控制传输层内的5G基站；控制传输层利用SDN控制器，按照ZigBee通信协议，控制通信终端内的船载终端通信装置向5G基站发送船舶航行数据，5G基站连接5G核心网络后，利用其将船舶航行数据传输到地面站的云数据中心层。该层使用云管门户、运营门户和运维门户对舰船航行相关数据进行管理，实现海上船舶与地面控制站之间的通信网络连接。实验结果表明，该系统具备较好的稳定性，其传输船舶数据时，传输速度较快，且网络节点接收功率损耗较小，应用效果较佳。
A ship network system based on 5G communication technology is designed to improve the connectivity between ship and ground control station during navigation. Based on B/S architecture, the system is connected to the 5G base station in the control transmission layer after collecting ship navigation related data through the shipborne terminal communication device in the communication terminal layer. The control transmission layer uses the SDN controller to control the shipborne terminal communication device in the communication terminal to send ship navigation data to the 5G base station according to the ZigBee communication protocol. After the 5G base station is connected to the 5G core network, the ship navigation data is transmitted to the cloud data center layer of the ground station through the 5G base station. This layer uses cloud management portal, operation portal and operation and maintenance portal to manage ship navigation-related data and realize the communication network connection between larine ships and ground control stations. The experimental results show that the system has good stability, the transmission speed of ship data transmission, and the network node receiving power loss is small, the application effect is good.
