Underground pipe network laying method based on three-dimensional virtual city

Abstract

The invention relates to an underground pipe network laying method based on a three-dimensional virtual city, comprising the following steps of: carrying out preprocessing on remote sensing image data, digital elevation model data and three-dimensional building model data to construct a three-dimensional virtual city system; realizing the generation and the management of an underground three-dimensional pipe network model based on pipe point data, pipe well data and two-dimensional pipeline data in the three-dimensional virtual city system; selecting a starting point and a terminal point needing a pipe network according to the underground three-dimensional pipe network model and generating various pipe network laying schemes; carrying out collision processing on the pipe network laying schemes according to relevant specifications and standards, searching pipe network ambient facilities and analyzing the pipe network laying influence factor; carrying out optimization analysis according to the pipe network laying influence factor to obtain an optimum scheme which is suitable for underground pipe network laying, and managing and showing a result in the three-dimensional virtual city system. The invention constructs the three-dimensional virtual city, generates optimization by dynamic modeling and various pipe network laying schemes, realize the laying of a pipe network on dependable basis and provides support for planning underground resources and pipe lines of the city.

Description

【Technical Field】 [0001] The invention relates to a method for laying an underground pipe network, in particular to a method for laying an underground pipe network based on a three-dimensional virtual city. 【Background technique】 [0002] The urban underground pipe network is responsible for information transmission, energy transmission, water supply and drainage and other tasks. It is the foundation of urban development and is therefore known as the lifeline of the city. However, with the rapid development of the city, the material flow and energy flow in the city are gradually increasing, making the spatial distribution of urban underground pipelines narrower and narrower. Discussion on the optimization method of underground three-dimensional pipeline network layout, for urban underground resource management, pipeline planning and urban planning Construction provides auxiliary decision-making, which is of great significance. [0003] Therefore, how to achieve better management o...

AI Technical Summary

Problems solved by technology

[0004]The traditional underground professional pipeline network adopts manual methods, which has low management efficiency and is difficult to dynamically manage the underground pipeline network, which is easy to cause pipeline accidents in narrow spaces

In addition, traditional underground pipe network management is based on two-dimensional, which cannot visually display the distribution of pipelines and the mutual positions of pipe segments
