A rapid generation method of umbilical routing profile

Abstract

The present invention provides a method for quickly generating a duct cable routing profile, including S1: inputting preset profile parameters, and calculating the length of the overlapping portion of two adjacent picture frames according to the profile parameters; S2: extracting the coordinate data of the picture frames, from Select a number of vertex coordinates from the coordinate data and obtain the frame length through the vertex coordinates; S3: Calculate the coordinates of each point of the frame according to the length of the frame; S4: Calculate the coordinates of two points of the grid line according to the coordinates of each point of the frame ; S5: Generate a picture frame length file and a command execution file according to the element attribute; S6: Determine whether the picture frame length in the picture frame length file complies with the drawing outline generation condition, if it complies with the drawing outline generation operation; otherwise, return to step S1. The invention can accurately calculate the coordinates of the picture frame, and at the same time, the data results can be generated into a .csv file of the outline length list, which solves the need for staff to mark each grid coordinate one by one according to the coordinate value of the location of the pipe cable, which is time-consuming and time-consuming. and prone to mislabeling.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to a method for rapidly generating a duct cable routing profile. Background technique [0002] In the field of marine surveying and mapping, the completion of marine surveying and mapping projects not only includes the completion of field survey work, but also the successful completion of project results. Excellent results of surveying and mapping projects can complement the survey results, show the owner more completely the exposed, suspended, scoured, and offset states of the subsea pipeline and provide accurate coordinates, so that the owner can repair the hidden subsea pipeline according to the surveying and mapping results to ensure the pipeline. The safe and normal operation of the pipeline can prevent production stoppage or marine environmental pollution caused by pipeline damage and destruction. [0003] Due to the limitation of the construction period,...

AI Technical Summary

Problems solved by technology

Due to the complex situation of the actual pipeline, its length is often long and there are many inflection points. In the process of pipeline profile processing, first of all, it is necessary for the office personnel to set the length of the profile and the length of the overlapping part according to the direction and length of the pipeline, and Drawing the frames one by one in CAD is complicated work and the position of the capture point is easily shifted, and the transition of the inflection point is rigid and not smooth enough; secondly, after the drawing of the profile is completed, the office staff need to locate the location of the umbilical cable according to the The coordinate value of , mark each grid coordinate one by one

Especially for long-distance pipelines, it often takes a lot of time for office workers to label, and there is a possibility of coordinate labeling errors

The emergence of these problems makes the results of the initially completed marine surveying and mapping project show the characteristics of low rigor and need for repeated inspections. It requires the office staff to spend a lot of time to eliminate possible errors, which greatly slows down the submission of surveying and mapping results. speed, reducing office worker productivity
