摘　　要：水声网络和北斗的结合为实时、原位、立体化的水下信息跨域传输提供了有效的技术手段。面向海洋环境监测应用,设计了一个基于北斗和水声网络的水下传感数据跨域传输系统并开展海试试验。该系统由多个水下传感节点与搭载北斗终端的跨介质节点组成,给出了系统水声网络物理层、MAC层、路由层及北斗模块接口设计。厦门港的海试试验表明:原始海洋环境传感数据与水声–北斗跨域传输岸基接收数据完全一致,水下网络可通率为92.5%,水下部分平均端到端延时为101.43 s,初步验证了北斗–水声网络数据跨域传输的有效性。The integration of underwater acoustic networks and BeiDou offers an effective technical solution for real-time,in-situ,and three-dimensional cross-domain transmission of underwater information.For Marine environmental monitoring applications,a cross-domain transmission system for underwater sensing information based on BeiDou and underwater acoustic networks is designed and tested.The system comprises multiple underwater sensor nodes and a cross-media node equipped with BeiDou module.The physical layer,MAC layer,and routing layer of the underwater acoustic network system,as well as the interface design of the BeiDou module are described.The sea trial in Xiamen port demonstrates complete consistency between original marine environment sensing data and the shore-based data transmitted through underwater acoustic-BeiDou cross-domain system,with an underwater network connectivity rate of 92.5%and an average end-to-end delay of 101.43 s for the underwater part,which preliminarily verifies the effectiveness of cross-domain data transmission using BeiDou-underwater acoustic network.
