基于5G 通信与北斗短报文的近海小型浮标通信系统设计方法

针对近海小型浮标仅采用单模方式与岸基进行通信的问题，提出一种北斗短报文与5G 通信相结合的近海小型浮标通信系统设计方法。搭建浮标与岸基指挥所的通信链路，实现岸基指挥所与浮标之间的远程信息交互功能，其中浮标采集的水文气象等信息通过当前锚定区域的最优通信链路上传至岸基指挥所，岸基指挥所远程控制浮标完成相应任务。实验室模拟结果表明：在5G 通信与北斗三号全球卫星导航系统技术支持下，本系统能够增强小型浮标在恶劣海况下的鲁棒性、提升数据传输的安全性以及提高通信质量。

A Design Method of Offshore Small Buoy Communication SystemBased on 5G Communication and Beidou Short Message

In order to solve the problem that offshore small buoys only use single mode to communicate with theshore-based, a design method of offshore small buoy communication system combining Beidou short message and 5Gcommunication is proposed. The communication link between the buoy and the shore-based command post is built torealize the remote information interaction function between the shore-based command post and the buoy, in which thehydrological and meteorological information collected by the buoy is uploaded to the shore-based command post throughthe optimal communication link in the current anchoring area, and the shore-based command post remotely controls thebuoy to complete the corresponding tasks. Laboratory simulation results show that with the support of 5G communicationand Beidou-3 global navigation satellite system technology, the system can enhance the robustness of small buoys in harshsea conditions, improve the security of data transmission and improve the quality of communication.
