Submarine optical cable burial depth detection equipment

Abstract

The invention provides submarine optical cable burial depth detection equipment. The submarine optical cable burial depth detection equipment comprises a transmitter, a submarine optical cable, a probe and a signal processing and displaying device. The transmitter is electrically connected with the submarine optical cable and outputs low-frequency sine waves to the submarine optical cable. The probe comprises a first coil, a second coil and a third coil, the first coil and the third coil are symmetrically arranged at the two ends of the probe, the second coil is located in the center of the probe, and the centers of the three coils are located on the same straight line. The second coil and the probe are coaxially arranged, and the axis of the first coil and the axis of the third coil are perpendicular to the axis of the probe. The probe wire moves in an area where a submarine optical cable to be detected is located. The first coil, the second coil and the third coil feed back measured induction electric signals to the signal processing and displaying device respectively. The signal processing and displaying device determines the route of the submarine optical cable and the distance between the probe and the submarine optical cable according to the three paths of induction electric signals. According to the invention, the burial depth of the submarine optical cable can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of submarine optical cable communication, in particular to a submarine optical cable buried depth detection device. Background technique [0002] With the continuous development of communication technology, the widespread use of submarine optical cables around the world has become the main means of cross-sea communication. At present, there are millions of kilometers of submarine optical cables in the world. In recent years, a large number of submarine optical cable communication lines have been built along the coast of my country for the communication of garrisoned islands. Since the extensive application of submarine optical cables, due to various reasons, including human and natural factors, there are many safety problems in submarine optical cable communication lines. On the one hand, natural disasters, such as earthquakes, can directly lead to the interruption of multiple submarine optical cables, caus...

Problems solved by technology

[0004] First of all, the burial depth of the submarine optical cable is an important indicator to determine the quality of the project during the construction of the line. Due to the lack of effective means, some existing submarine optical cable projects can only be obtained according to the state of the construction party's buried equipment. Facts have proved inaccurate and The lack of objectivity makes it difficult for the construction unit to grasp the construction quality
