Research of Submarine Cable Route Detection Technology Based on Three-dimensional Magnetic Field Measurement

为了精确、快速地检测海底电缆路由,研究了基于高精度三维磁场测量的海缆路由检测机制与反演算法,研制了相应的探测系统,实现了在海缆附近对海缆方位的实时探测。通过在舟山海域开展不同探测方式的比对试验,对海缆路由检测方案进行分析,得出多次切割海缆并沿缆航行的小S形航行检测方案既可以分辨出海缆的三相线,又能得到海缆精确路由走向的结论。为海缆高精度、高效率路由检测提供了理论依据。

In order to detect submarine cable route accurately and quickly,the mechanism and inversion algorithm of submarine cable route detection based on high-precision three-dimensional magnetic field measurement are studied,and the corresponding detection system is developed to realize the real-time location detection of the submarine cable around.The submarine cable route detection schemes are analyzed through comparison test of different detection methods in Zhoushan sea area.It is proposed that a small S-shaped navigation detection scheme along the cable that cuts the cable several times can not only distinguish the threephase line of the cable but obtain the accurate route direction of the cable.This research provides a theoretical basis for the high-precision and high-efficiency route detection of the submarine cable.
