Embodiment Construction

[0026] The present invention is further illustrated in conjunction with specific embodiments. It will be appreciated that these examples are intended to illustrate the scope of the invention and are not intended to limit the scope of the invention. It will be appreciated that after reading the present invention, those skilled in the art can make various modifications or modifications of the present invention, which also fall in the scope of the claims appended claims.

[0027] like figure 1 , The submarine cable locating method of an ultra-shallow vessel of the present invention provides a multi-joint, for ultra-shallow operating environment, the existing ship positioning system needs to be upgraded, so that one interface may simultaneously achieve a plurality of moving objects (vessels) and controlling a display, comprising the steps of:

[0028] Step 1, on a barge anchoring boats and two are attached to the positioning system. When mounting the positioning system, the installati...

Abstract

The technical problem to be solved by the invention is that no method capable of realizing multi-ship positioning in a full-automatic and real-time manner exists in the ultra-shallow water multi-shipcombined submarine cable construction process at present. In order to solve the technical problem, the technical scheme of the invention provides an ultra-shallow water multi-ship combined submarine cable construction positioning method. According to the method, DGPS is adopted for real-time differential positioning, so that the precision is improved, wherein the precision in a continental shelf area is smaller than 1 m; an ultra-long-distance wireless local area network system is used for networking multiple ships, so that it is guaranteed that the multiple ships can conduct reliable communication on the sea without mobile signal coverage; and software designed by the invention can display a plurality of moving objects on the interface of the same positioning software, the positioning andconstruction operations of a plurality of ships are relatively independent, and a barge can effectively monitor the positioning of the anchoring boat and send out an instruction.

Description

Technical field [0001] The present invention relates to an ultra-shallow vessel plurality submarine cable joint technical construction, technical field belonging to the submarine optical cable construction method. Background technique [0002] The traditional submarine cable installation is usually operated independently by a single submarine cable ship. In the ultra-shallow water barge operating environment, the traditional boat submarine cable construction due to the limitations of the ship's draft can not enter the super shallow water construction, therefore, ultra-shallow submarine cable construction is usually done using a shallow draft. [0003] Self-propelled barge is usually no power, so in order to achieve accurate positioning of the cable routing and cable without damaging purposes, barge barges to be achieved precise positioning and movement on the sea by helping to anchor boats during construction. [0004] Moving the barge specific method is as follows: [0005] 1, g...
