Problems solved by technology

However, due to the single sensor of these traditional methods, the probe coil needs to move back and forth on the submarine cable to find the peak point or the dumb point to determine the position and direction of the submarine cable, which is easy to cause misjudgm

Embodiment Construction

[0027] The invention proposes a five-rod submarine cable detection antenna array with adjustable side lengths. By rationally selecting the number of probes and optimizing its structure, a square array is formed, and the side length of the square is adjustable. The side length of the array can be adjusted according to the actual measurement site conditions to achieve the best measurement effect. Each point can get a set of parameters of the submarine cable, so it can efficiently and accurately measure the route and buried depth of the submarine cable, which has high practical value.

[0028] Such as figure 1 , the antenna array is composed of five probes, and the materials used to manufacture the probes require high magnetic properties, and a rod-shaped iron core is generally used. Copper wire coils are wound on the probe, because the antenna array measures the magnitude of the induced electromotive force, and the magnitude of the induced electromotive force is proportional to...

Abstract

Provided are a five-rod type side-length-adjustable type submarine cable detection antenna array and a detection method thereof. The five-rod type side-length-adjustable type submarine cable detection antenna array comprises an antenna array and a data transmitting module. Data of the antenna array are transmitted to an upper computer through the data transmitting module in a wired mode. The side length of the antenna array can be adjusted to optimize measurement results according to different on-site actual measurement conditions. When measurement is performed, one group of values of the burial depth, declination angle and deflection distance of a submarine cable can be obtained at each measurement point, the deflection distance and the declination angle are obtained according to measurement, the detailed position of the submarine cable is drawn with a curve by enabling the obtained deflection distance and the declination angle to be matched with global positioning system (GPS) positioning, the burial depth and the route of the submarine cable are obtained, the accuracy is greatly improved by the detection method in comparison with a traditional method, the measurement efficiency is high, and the five-rod type side-length-adjustable type submarine cable detection antenna array is easy to install.

Description

technical field [0001] The invention relates to a submarine cable detection antenna array with a new structure, which can conveniently measure the routing and buried depth of the submarine cable in real time according to different on-site actual measurement situations, and is a five-rod type submarine cable detection antenna with adjustable side lengths array. Background technique [0002] With the continuous development of communication technology, submarine cables, including submarine cables and submarine optical cables, have become the main means of cross-sea communication and are widely used around the world. At present, there are hundreds of thousands of kilometers of submarine cables in the world. Since the extensive use of submarine cables, due to various reasons, including human and natural factors, there have been many safety problems in submarine cable communication lines. On the one hand, the damage caused by natural disasters, on the other hand, various offshore...
