Problems solved by technology

In particular, the underground pipe network is not easy to detect because it is deeply buried in the ground, making it difficult to grasp the specific situation in case of sudden accidents in the pipe network, resulting in secondary accidents

Embodiment 1

[0036] figure 1 It is a schematic flowchart of a method for establishing a pipeline network model provided by an embodiment of the present invention. like figure 1 As shown, the method for establishing a pipe network model provided by this embodiment of the present invention includes steps S110 and S120.

[0037] In step S110, the pipe network information is read from the pipe network file.

[0038] The pipe network file is an engineering file and an electronic version drawing file, etc. related to the pipe network, and parameter information about the pipe network is usually marked in such a file.

[0039] Taking the pipe network file as an example in dgn format, the information such as the starting point coordinate value, pipeline name and pipe diameter of the pipeline in the dgn file can be parsed. The read information can be directly applied to model building, or can be used to its in other format files.

[0040] The pipe network information includes data about the pipe...

Embodiment 2

[0049] Considering that compared with the actual pipe network structure, the data in the pipe network file may not be the latest data, so the 3D model of the pipe network built according to the pipe network file is deviated from the pipe network file.

[0050] On this basis, on the basis of the constructed three-dimensional model of the pipe network, this embodiment of the present invention also provides an improved construction method, figure 2 It is a schematic flowchart of the method provided in this embodiment. like figure 2 As shown, the method provided by this embodiment of the present invention includes steps S210 to S230.

[0051] In step S210, a three-dimensional model of the first pipe network is obtained.

[0052] In step S220, a user instruction is received.

[0053] The user instruction may be received in any manner, for example, a signal input through an external input device such as a mouse, a keyboard and a display may be used as the user instruction.

Embodiment 3

[0061] Pipelines can be divided into various types according to their functions, such as pipelines for protecting cables and pipelines for transferring substances. Specifically, the substances transferred by the pipeline may include domestic water, fire-fighting water, automatic spraying water, sewage, drainage, heating substances, reclaimed water, rainwater and wind (including exhaust and supply air).

[0062] Taking the pipeline network including pipelines that need to transmit flowing substances as an example, in order to make the built pipeline network model more realistically reflect the actual pipeline network environment, on the basis of the initially built three-dimensional model of the pipeline network, the present invention also provides a A 3D model showing the flowing material inside the pipeline.

[0063] Specifically, the method provided by this embodiment of the present invention includes: acquiring a substance flowing inside a pipeline of a three-dimensional mo...

Abstract

The invention provides a method and device for establishing a pipe network model, and belongs to the technical field of modeling. The building method of the pipe network model comprises the following steps: reading pipe network information from a pipe network file; and building a first pipe network three-dimensional model according to the pipe network information. According to the technical scheme, building of the pipe network three-dimensional model can be automatically completed based on the pipe network file, the manual workload can be effectively reduced, the modeling period is shortened, and the pipe network three-dimensional model built in the mode has the advantages of being low in manufacturing cost and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of modeling, in particular to a method and a device for establishing a pipe network model. Background technique [0002] With the development trend of petrochemical plants becoming gigantic, the demand for the number of pipelines is also increasing rapidly, and the structure of the pipeline network system also becomes complicated. In particular, the underground pipe network is deeply buried in the ground and is not easy to detect, which makes it difficult to grasp the specific situation in the event of an accident in the pipe network, resulting in secondary accidents. [0003] The three-dimensional virtual display model of the pipe network scene can improve the three-dimensional and realistic sense of the pipeline, which is conducive to a comprehensive and realistic reflection of the criss-cross and ups and downs of the above-ground and underground pipe networks. At present, the 3D modeling of underground p...
