Embodiment Construction

[0066] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0067] Such as figure 1 As shown, the present invention includes a buried submarine cable construction ship 1, a buried plow 2 dragged by the buried submarine cable construction ship 1, a survey ship 3 positioned at the rear side of the submarine cable construction ship, and an ultra-short baseline changer located on the survey ship 3. Energy device 4, 4 ultra-short baseline beacons 5 located on the buried plow 2;

[0068] When burying the submarine umbilical cable 6, the submarine umbilical cable 6 on the submarine cable construction ship is continuously buried into the seabed 7 through the burying plow 2 by the buried submarine cable construction ship 1 dragging the burying plow 2; The ultra-short baseline transducer 4 is immersed in the water downward, and the ultra-short baseline transducer 4 receives the signal from the ultra-s...

Abstract

The invention discloses a submarine pipe cable burying underwater positioning system and a working method thereof and relates to the field of submarine pipe cable burying. When a submarine pipe cable burying plough works, the submarine pipe cable burying plough is invisible, and an effective method for obtaining the posture of the burying plough in real time is lacked. The system comprises a submarine cable burying workboat, a burying plough, a surveying boat, an ultra-short baseline transducer and a plurality of ultra-short baseline beacons arranged on the burying plough, an object coordinate system is set on the burying plough, the position vector of the ultra-short baseline beacon under the object coordinate system and the position vector of the submarine cable under the object coordinate system are determined according to the structural shape and size of the burying plough, and different burying depths correspond to different submarine cable conduit positions; during operation, the ultra-short baseline transducer is used as an original point, a global coordinate system is established, and the position information of the ultra-short baseline beacon is obtained through ultra-short baseline beacon positioning. According to the system, the method is simple, working is reliable, and the real-time position of the submarine pipe cable can be accurately obtained in real time.

Description

technical field [0001] The invention relates to the field of submarine umbilical cable embedding, in particular to an underwater positioning system for submarine umbilical cable embedding and a working method thereof. Background technique [0002] When the submarine umbilical plow is in operation, since the submarine umbilical plow is invisible, there is no effective method to obtain the posture of the buried plow in real time, and then know the real-time position of the submarine umbilical. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and improve the existing technical solutions, and to provide a submarine umbilical buried underwater positioning system to obtain the posture of the buried plow, and then know the real-time location of the submarine umbilical. purpose of the location. For this reason, the present invention takes the following technical solutions. [0004] An un...
