Dynamic computing method for construction period of submarine cable operation

Abstract

The invention discloses a dynamic computing method for a construction period of submarine cable operation. The method includes the steps of firstly building a seabed profile model according to prospected seabed parameters, and setting a construction starting coordinate point; according to the construction coordinate point and the default speed of submarine cables, building a margin model, a submarine-cable type transition coordinate point and a grounding coordinate point, obtaining a submarine cable laying length model, creating a gradient critical-point coordinate point, building a ship speed adjusting model and a transition margin adjusting model, setting a construction ending coordinate point, and then creating a margin model; finally obtaining construction period data, and determining the construction period of the implementation scheme which needs to be executed. According to the dynamic computing method for the construction period of the submarine cable operation, by setting and computing the seabed profile model, the construction coordinate points and corresponding data are obtained to achieve full-period instruction and construction period control of submarine cable laying, and therefore laying work of the submarine cables can be conducted successfully and effectively, and more convenience is provided for people to precisely and timely monitor the process of submarine cable laying so that construction efficiency is improved and a controllable construction period is ensured.

Description

technical field [0001] The invention relates to the technical field of submarine cable routing, in particular to a method for controlling the construction period of a submarine cable operation. Background technique [0002] With the development of communication technology, information exchange has become more and more common. Long-distance communication requires the installation of communication cables to ensure the rapid transmission of information. [0003] my country's coastline is about 18,000 kilometers, and it has more than 5,000 islands or islands. Some of these islands or islands have long-term human populations. Both the development of islands and the protection of sea area resources require the establishment of a submarine cable communication resource network. Compared with the difficulty of laying submarine cables on land, it can be seen that the difficulty of laying submarine cables on the seabed is average. With the rapid development of various technologies toda...
