Abstract: 
cabled seafloor observatories play an important role in ocean exploration for its long-term, real-time, and in-situ observation characteristics. In establishing a permanent, reliable, and robust seafloor observatory, a highly reliable cable switching and fault isolation method is essential. After reviewing the advantages and disadvantages of existing switching methods, we propose a novel active switching method for network configuration. Without additional communication path requirements, the switching method provides a way to communicate with a shore station through an existing power transmission path. A coded voltage signal with a distinct sequence is employed as the communication medium to transmit commands. The analysis of the maximum bit frequency of the voltage signals guarantees the accuracy of command recognition. A prototype based on the switching method is built and tested in a laboratory environment, which validated the functionality and reliability of the method.

基于可编程电压信号实现海底观测网海缆切换及故障隔离

摘要:缆系海底观测网可实现长时间、实时、原位海洋在线观测,在海洋观测领域扮演重要角色。可靠的海缆切换方法对于建立永久、可靠、鲁棒性高的海底观测网是必要的。对比已有海缆切换方法优缺点,针对海底观测网的网络组态提出一种新颖的海缆切换方法。无需配置额外通讯路由,借助已有电力传输缆,传输基于特定序列的可编程电压信号,实现水下分支器与陆地岸基站的通讯。建立系统仿真模型,分析电压信号最大数据位频率,确保准确识别控制命令。最后,在实验室环境下建立基于所提切换方法的水下分支器样机,验证该方法的功能及可靠性。

关键词:缆系海底观测网;海缆切换及故障隔离;可编程电压信号;最大数据位频率
