摘要

摘要: 海洋浮标具有使用灵活、开发便利、结构简单等优点, 在海洋领域已经有了大量应用。然而现有海洋浮标通信方式单一、可靠性低、丢包率高且实时性差, 无法满足海洋数据大量采集与跨域通信的需求。为了进一步加强海洋全域互联互通建设, 以多源通信为核心, 设计并制作了一种跨域通信浮标系统, 该系统可完成多种通信方式的切换、多源信息采集与多链路实时跨域通信。针对系统设计了一种最优通信链路选择算法, 根据各通信模块实时信号质量, 进行最优通信链路的选择, 提高通信的可靠性, 同时关闭信号质量较差的通信模块, 减少同时使用多种通信手段可能出现的系统通信大量冗余与功耗增加的问题。试验结果表明, 该系统实现了水上与水下数据的跨域传输, 多源通信设计切实可行, 各通信链路稳定可靠, 综合通信成功率达99%以上, 为海洋全域观测网和通信网的建设提供了参考。

Abstract: The ocean buoy has the advantages of flexible use, convenient development and simple structure, and has been widely used in the marine field. However, the existing marine buoy communication mode is single, low reliability, high packet loss rate and poor real-time performance, which cannot meet the needs of large-scale marine data acquisition and cross-domain communication. In order to further strengthen the construction of marine global interconnection, this paper designs and manufactures a cross-domain communication buoy system with multi-source communication as the core. The system can complete the switching of multiple communication modes, multi-source information acquisition and multi-link real-time cross-domain communication. An optimal communication link selection algorithm is designed for the system. According to the real-time signal quality of each communication module, the optimal communication link is selected to improve the reliability of communication. At the same time, the communication module with poor signal quality is closed to reduce the problem of large redundancy and power consumption of system communication that may occur when multiple communication methods are used at the same time. The experimental results show that the system realizes the cross-domain transmission of water and underwater data, and the multi-source communication design is feasible. The communication links are stable and reliable, and the comprehensive communication success rate is more than 99%. It provides a reference scheme for the construction of marine global observation network and communication network.
