基于民用北斗的海洋资料浮标安全通信机制研究

Research on the Security Communication Mechanism of Marine Data Buoy Based on the Civil Beidou

为了解决针对多台浮标系统同时工作,并通过民用北斗卫星向岸站实时安全地传送数据的问题,通过设计一种可行的通信机制来实现单点式终端接收多台发射端数据。介绍了整个浮标通信的框架和通信终端的具体接收实现,并在实验室条件下,研究了在多台标体同时发送观测数据的情况下接收终端的通信机制。最后经过大量的海试试验验证,现已实现三台浮标的并网实时传输数据的功能,并预留相应接口,可满足添加更多台浮标的需求。

In order to deal with the simultaneous work of the multi-buoy system and the real-time secure data transmission tiom the civil Beidou satellite to the shore station, a tasible communication mechanism to support the single-point terminal receiving multi-transmitter data was designed in this paper. The complete buoy communication framework and the detailed terminal reception implementation were introduced. The receiving terminal＇s communication mechanism when multiple targets transmit observational data simultaneously was investigated through laboratory experiments. Finally, lots of sea trials demonstrate that the simultaneous real-time data transmission of three buoys is implemented and corresponding interfaces are reserved to meet the requirement of adding more buoys.
