Automatic Generation Method of 3D Equipment and Pipeline Model of Subway Station Pipeline

Abstract

The present invention relates to a method for automatically generating a three-dimensional equipment pipeline model of a subway station, comprising: step 1, acquiring spatial information of passages used for pipeline arrangement, wherein the passages are divided into multiple passage segments, and the spatial information includes record The path segment information of the position of the path segment; step 2, obtain the endpoint information of each pipeline that needs to be arranged, and the pipeline size information; step 3, according to the information obtained in steps 1 and 2, obtain all the possibilities of each pipeline Then, each pipeline selects a possible pipeline path, and after permutation and combination, multiple candidate pipeline arrangements including the pipeline path of each pipeline are obtained, wherein the pipeline path is determined by the passage it passes through Fragment representation; step 4, according to the pipeline information on each path segment passed by the pipeline path in each candidate pipeline layout scheme, select one from the candidate pipeline layout scheme as the optimal pipeline layout scheme .

Description

technical field [0001] The invention relates to the technical field of computer-aided design of construction engineering, in particular to a method for automatic layout of subway station pipelines. Background technique [0002] In the construction of rail transit facilities (such as subway stations), it is necessary to lay a large number of various pipelines. The pipelines involved in each subway station range from a dozen to as many as several hundred. Not only are they numerous in number, but they are also of various types, involving different specialties. [0003] At present, the designers of the global layout of pipelines need to gather together the pipeline diagrams drawn by various professional designers separately, and then observe each section along the corridor. If there are conflicts and collisions, they need to be adjusted one by one to ensure the previous adjustments as much as possible. No changes occur until all parts are adjusted. Then, feed back the adjuste...

AI Technical Summary

Problems solved by technology

[0004] The above process leads to the following problems: it takes a long time for the designer to modify the design; the special design manually made by the designer has a high probability of error; during the review of the pipeline relocation design, it is difficult to modify and demonstrate the modification suggestions put forward by the participants on the spot , which increases the difficulty of review and reduces the efficiency of review, and it is not easy to find problems and prone to design defects
