Embodiment

[0016] When carrying out the steps of the present invention, it is necessary to collect the following data: the real-time tension and speed of the cable output by the speed and tension sensor on the cable laying machine; Data such as equipment speed and dive depth; ship position data transmitted through the satellite global positioning system; water depth and seabed condition data transmitted through the sonar detector; ship direction data transmitted through the compass; Ocean Survey Data.

[0017] Data collection is carried out through a collection program, which can convert the data of the RS232 serial port into a program of network data source, and then the server on the network can easily read the data collected by the COM port on any computer through the network. data. After the computer system collects the above data, it can calculate the ship speed and the margin of cable laying on the seabed through the server, and then calculate the ship position, water depth, ship ...

Abstract

The invention provides a cable paving, salvaging and integrating method, characterized in steps of using a differential GPS to position a cable ship and control route of the ship, recording and printing data in the process, then paving cables in sailing of the cable ship, setting left amount of paving according to actual seabed situation, after the cables are completely released, outputting all positioning points collected by the differential GPS and cable laying depth obtained by an underwater device control cabin of the cable ship in a fixed data format for convenience of future maintenanceneed. The invention has the advantages of effective cable paving, salvaging and integrating method and the method not only brings high paving precision but also brings convenience for future maintenance need.

Description

technical field [0001] The invention relates to a cable laying and salvage control technology, and belongs to the technical field of submarine optical cable construction methods. Background technique [0002] The installation of submarine cables is divided into two types: direct laying and burying. Direct laying means that the submarine cable is directly placed on the surface of the bottom of the sea; the burial of the submarine cable needs to be buried in the bottom of the sea with a special cable burying plow or burial equipment to enhance the protection of the submarine cable. During the submarine cable landing construction, the landing part of the submarine cable is not directly buried, and the buried depth of this part of the submarine cable is completed after the landing construction is completed. [0003] Submarine cable laying is a complicated and tedious work in the construction of submarine optical cable system. In large-scale submarine cable system construction ...
