Problems solved by technology
[0012] The purpose of the present invention is to provide a three-dimensional visualized subway comprehensive pipeline operation and maintenance system, which solves the problem that when the existing subway comprehensive pipeline is operated and maintained, the two-dimensional static management cannot express the spatial form of the pipeline entity and the spatial topological relationship between the pipelines. There is a phenomenon of inconsistency between the pictures and the facts, and the problem of lack of unified management

Embodiment
[0118] Take Xi'an City Library Subway Station and combine Figure 12 Some of the comprehensive subway pipelines listed in are taken as examples. Proceed as follows:
[0119] Step ①: First of all, conduct a field investigation on the subway station of Xi'an City Library, and extract it from the AutoCAD drawing Figure 12 The pipeline data described in . Provide data support for the scene modeling of the subway and the 3D visualization management of the integrated pipeline.
[0120] Step ②: Design two database tables and create 5 XML files. One database table is used to store the class information of the two types of pipelines, air pipes and water pipes, and the other is used to store the basic attribute information of air-conditioning air supply pipes, fresh air pipes, exhaust pipes, drain pipes, and sewage pipes. Five XML files are used to store the spatial information and laying information of the five pipelines respectively.
[0121] Step ③: According to Figure 4 Crea...

The invention discloses a three-dimensional visual operation maintenance system of subway comprehensive pipelines, comprising a user management module, a data acquisition and storage module and a three-dimensional modeling module which are connected in sequence, wherein the three-dimensional modeling module is also connected with an operation and maintenance module and a three-dimensional displaymodule respectively. In an operation maintenance method based on the system, firstly subway pipeline data is extracted from drawings and is input into the data acquisition and storage module; and secondly, the three-dimensional modeling module establishes a three-dimensional model according to the subway pipeline data, comprehensive pipelines and subway scenes are displayed by the three-dimensional display module in a three-dimensional effect, and maintenance management is carried out on the subway comprehensive pipelines by the operation and maintenance module. By the maintenance system and the maintenance method, data sources are accurate, and the problem that the drawings does not conform to the reality is solved; and in the unified management mode, the space layout of all special pipelines can be mastered by scene roaming, the integrated browsing and control of the space of all the layers and all the pipelines of subway scenes is realized.
Description
technical field [0001] The invention belongs to the technical field of urban rail comprehensive pipeline operation and maintenance, and specifically relates to a three-dimensional visualized subway comprehensive pipeline operation and maintenance system. The invention also relates to a method for using the above-mentioned system to perform three-dimensional visualized subway comprehensive pipeline operation and maintenance. Background technique [0002] With the continuous development of my country's urban rail transit, especially the construction of subways, the scale of integrated subway pipelines has become increasingly complex. As an important part of urban construction, once the subway comprehensive pipeline is completed, it will have the following characteristics: [0003] 1. Concealment of spatial location: Metro integrated pipelines are usually laid underground or on the ceiling, and it is difficult to determine their specific spatial location without relevant constr...
