摘　　要：通过对分布式光纤传感技术及布里渊光时域反射领域国内外研究应用情况的介绍,阐述了利用光电复合海缆富余光纤作为传感元件进行海缆在线监测研究的技术路线。着重论述分布式光纤温度和应变传感技术原理及基于BOTDR海缆本体状态实时在线监测的研究;船舶自动识别系统(AIS)和视频系统构建的肇事船只确认子系统可以与BOTDR系统联动,提前预警海缆异常状态,确认肇事船只;探讨海洋磁力计对海缆故障点进行水下定位方法。文章归纳总结了从海缆本体状态监测到海上肇事船只确认及海缆故障点定位的海缆立体监测研发成果,该成果在海洋环境下有着广泛的推广应用前景。Through introducing the research and application of the distributed optical fiber sensing technology and Brillouin optical time domain reflect at home and abroad, this paper expounds the technical route of online monitoring of photoelectric composite submarine cable through using the redundant optical fibers as sensing elements. It emphasizes on the principle of distributed temperature and strain sensing technology, and the research of online monitoring of submarine cable based on BOTDR. It also emphasizes on the research and development of the ship verification subsystem for the early warning of submarine cable abnormality by interacting with BOTDR system, which consists of Autonomous Identification System （AIS） and video system. It discusses the method of undersea positioning using the marine magnetometer. The paper summarizes the research results of the integrated online monitoring system for submarine cable. The results have the broad application prospect in the marine environment.
