Research on Method to Prevent External Damage of Submarine Cable by Distributed Optical Fiber Sensing System with Φ-OTDR

本文以陆地电缆为研究对象,利用Φ-OTDR分布式光纤传感系统建立陆缆防开挖数据模型,并应用于实际现场试验,验证了建模的正确性以及定位的准确性。在Φ-OTDR分布式光纤传感系统上建立陆缆防破坏综合系统。本文研究内容可以为陆地电缆防开挖提供技术支持,减少陆缆被人为破坏的可能性,保护用电线路安全。

This paper choose Land cable as the research object. The land cable anti excavation data model was established by distributed optical fiber sensing system with Φ-OTDR. The model applied to the actual field experiments to verify the modeling accuracy and positioning accuracy. The establishment of land cables in distributed optical fiber sensing system with Φ-OTDR on anti damage integrated system. The research content of this paper can provide technical support for the ground cable to prevent excavation, reduce the possibility of damage to the land cable, and protect the safety of the electric line.
