Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when laying the ocean-going submarine cable, the repeater of the submarine cable needs to be launched together with the submarine cable, so that the diameter of the submarine cable entering the cable laying machine changes, and the diameter change will cause the traction roller The pressure acting on the submarine cable changes, which in turn causes the tension of the submarine cable to change

Abstract

The invention relates to a submarine cable laying wheel set gap adjusting method and system, and relates to the technical field of submarine cable laying, and the method comprises the steps: obtaining and storing the shape data of a to-be-laid submarine cable; establishing and storing theoretical pressure data of each traction pressing wheel during cable laying; according to the theoretical pressure data and the shape data, based on a preset distance estimation algorithm, generating theoretical distance data when each position of the submarine cable to be distributed passes through each traction pressing wheel; collecting traction wheel speed data and pinch roller position data when the cable laying machine lays the cable, and collecting laid cable length data of the cable laying machine; calculating and generating position data of the submarine cable in the cable laying machine according to the traction wheel speed data and the laid cable length data; and based on the shape data and the position data, comparing theoretical distance data, and adjusting the position data of the pinch roller. According to the invention, the tension consistency of submarine cables with different diameters in the cable laying machine can be better ensured.

Description

technical field [0001] The present application relates to the technical field of submarine cable laying, and in particular, to a system and method for adjusting the gap of a submarine cable laying wheel set. Background technique [0002] Submarine cables are cables wrapped with insulating material and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers as the material to transmit telephone and Internet signals. [0003] When the submarine cable is laid in the deep sea, a cable laying machine is required. There are multiple sets of traction pressure rollers arranged in pairs on the cable layout machine. The traction pressure rollers include upper and lower pairs of traction rollers and pressure rollers. , the speed of the motor is controlled by the control module or the other, and the lifting height of the pressing wheel is controlled by...
