Abstract

The invention discloses a method and device for detecting submarine cables, including: adjusting the detector's voltage signal according to the first alternating voltage signal of the first coil array of the detector and the second alternating voltage signal of the second coil array. position until the detector is directly above the cable under test; calculate the first angle between the detector and the cable under test according to the first alternating voltage signal; calculate the first angle between the detector and the cable under test according to the second alternating voltage signal Calculate the second angle between the detector and the cable under test from the voltage signal; obtain the roll angle of the detector; according to the first angle, the second angle, the roll angle and The length between the first coil array and the second coil array obtains the position information of the cable to be tested. By obtaining the roll angle, the precise position of the submarine cable can be detected.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and device for detecting submarine cables. Background technique [0002] With the development of science and technology, submarine cables are widely used. Accurately grasping the location of submarine cables is very important for the operation and maintenance of submarine cables. However, the existing technologies, whether it is multi-beam side-scan sonar detection, underwater robot camera, acoustic pipeline instrument detection, etc., are all limited by the marine environment and cannot accurately obtain the location of submarine cables. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method and device for detecting a submarine cable, which can detect the precise position of the submarine cable. [0004] Based on the above-mentioned purpose, a method for detecting submarine cables provided by the present inven...
