【摘要】：随着科技的进步,各种海底传输网络正向着大容量、长距离、高兼容的方向发展,而建立统一的海底信息网传送平台是一个主流趋势。海底信息网需囊括现有的海底光缆系统、海底观测网系统和海底警戒网系统的全部功能,是实现海底通信的一体化管理的重要方式。海底信息网是水下多节点系统的一种实现,其包含了海底信息网的结构设计、水下节点设计和功能子系统的设计三个方面,本文也据此从三个方面进行研究。首先介绍现有海底网络的发展情况,包括具体系统的关键技术和应用场景,分析海底信息网建设的必要性,并对海底信息网架构进行研究与设计。从整体网络拓扑结构出发,探讨了各种拓扑结构的利弊,并具体分析了海底光缆系统和海底观测网系统的网络结构和实现方式,为后续设计做借鉴。然后根据海底信息网的各方面的技术实现,给出相应的可行性方案。最后根据三种不同业务网络的特点,阐述海底信息网的运作流程。其次介绍了海底信息网中关键水下节点接驳盒的信息系统框架,基于模块化设计的原则,给出了接驳盒的模块化设计方案,并针对每个功能模块作详细说明。最后从海底信息网中线路监测子系统的角度出发,详细研究了基于OTDR技术的线路检测系统的实现,结合COTDR光纤分布式传感原理,给出线路监测系统的系统架构和可行的实施方案。
[Abstract]:With the development of science and technology, various undersea transmission networks are developing towards the direction of large capacity, long distance and high compatibility, and it is a mainstream trend to establish a unified undersea information network transport platform. The submarine information network needs to include all the functions of the existing submarine optical cable system, submarine observation network system and submarine alert network system. It is an important way to realize the integrated management of submarine communication. Submarine information network is a kind of realization of underwater multi-node system, which includes three aspects: structure design of submarine information network, design of underwater node and design of function subsystem. This paper first introduces the development of the existing submarine network, including the key technologies and application scenarios of the specific system, analyzes the necessity of the construction of the submarine information network, and studies and designs the architecture of the submarine information network. The advantages and disadvantages of various topologies are discussed from the perspective of the overall network topology, and the network structure and realization of submarine optical cable system and submarine observation network system are analyzed in detail, which can be used for reference for the subsequent design. Then according to the various aspects of the submarine information network technical realization, the corresponding feasibility scheme is given. Finally, according to the characteristics of three different service networks, the operational process of submarine information network is expounded. Secondly, the information system frame of the key underwater node connection box in the submarine information network is introduced. Based on the principle of modularization design, the modular design scheme of the connection box is given, and each function module is explained in detail. Finally, from the point of view of line monitoring subsystem in submarine information network, the realization of line detection system based on OTDR technology is studied in detail, and the principle of COTDR fiber distributed sensing is combined. The system architecture and feasible implementation scheme of the line monitoring system are given.
