北斗RDSS在海洋工程数据传输中的应用

海洋一直是传统通信技术的最大盲区.因为缺乏有效的通信手段,造成船岸之间信息交流困难,高度信息化的海上工程船舶成为漂浮在海上的信息孤岛.北斗卫星导航系统将导航与通信集成,为解决船岸一体化提供了可行的技术途径.本文基于北斗RDSS(Radio—Determina—tion Satellite Service,卫星无线电测定业务)短报文通信原理,提出了北斗集群数传解决海洋工程船大数据量传输的技术方案.通过制定通信协议,建立有效的数据处理算法和压缩算法,将包含船机状态数据、施工工况数据、船位信息等数千个物理量实时发送到岸上指挥中心,实现了海上作业的船岸一体化,为海上作业船舶的生产调度和业务管理提供了信息技术保障.

Application of BD RDSS for marine data transmission

The ocean is always one of the biggest blind spot of traditional communication technologies. Because of lack of effective means of communication, resulting in information communication difficulties between ship and shore, highly informatization of offshore marine engineering ships have become floating “information islands” in the sea. Beidou Satellite Navigation System has integrated navigation and communication, which has provided a feasible technology way to solve the
 Vessel-Shore Integration. This paper proposed a Beidou cluster data transmission technology solution based on short message communication principle of Beidou RDSS (radio determination satellite Service), which solves the problem of large amount of data transmission for marine engineering ships. The software can transmit thousands of physical quantity containing ship machine state data, construction condition data, position information to shore command center in real-time through the development of the communication protocol, the establishment of an effective algorithm of data processing and compression algorithms, which realizes the Vessel-Shore Integration of offshore operations and provides an information technology security for the ship scheduling of production and business management.
