Description

Technical Field

[0001] The present invention relates to the field of building information technology, and in particular to a cloud-based BIM model data parsing method. Background Art

[0002] BIM is widely used in the construction industry because of its rich real engineering data and accuracy, and BIM technology has been widely developed domestically and even internationally. The accuracy of construction engineering is one of the advantages of BIM technology, but because of this, this advantage is also its defect and bottleneck in the effective transmission and utilization of BIM. As we all know, under limited bandwidth conditions, the amount of data is proportional to the time consumption. Because of this, in order to reflect the actual appearance of the construction project, the more accurate the BIM model of the construction project, the more data it has, which brings about problems in the management of the BIM model, and it is highly dependent on the revit tool, making it very inconvenient to view and manage the data.

[0003] At present, the amount of data in the design phase of ordinary construction engineering BIM models can reach hundreds of megabytes or even gigabytes due to the business accuracy restrictions (similar to the LOD standard restrictions often mentioned in the industry). With the continuous development of hardware storage capacity, although the problem of storing gigabytes of data is no longer a difficult task, the problem of transmission and management of BIM models has always existed, as well as the problems of data extraction and real-time viewing.

[0004] In summary, the problems with the existing technology are: the process of parsing the BIM model to obtain valid data is very complicated, and the extracted data does not have a clear format, which is very unfriendly to users. Summary of the invention

[0005] The purpose of the present invention is to provide a cloud-based BIM model data analysis method, which is simple to operate, has a small amount of data, and is easy to apply.

[0006] The technical solution to achieve the purpose of the present invention is:

[0007] A cloud-based BIM model data parsing method comprises the following steps:

[0008] (10) Model file acquisition: Obtain BIM model files from the cloud and add them to the data analysis queue;

[0009] (20) Model file logic processing: performing corresponding logic processing according to the model type corresponding to the BIM model file;

[0010] The model types corresponding to the BIM model file include civil engineering model and electromechanical model;

[0011] (30) Calculation of the room where the equipment is located: By using the secondary development application interface provided by Revit, the BIM models of the civil engineering model and the electromechanical model of the same floor are loaded at the same time. Based on the space information and equipment information, the room where the equipment is located is calculated and the data is stored.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] 1. Simple operation: Through existing technologies, this automated process realizes the online management of BIM models, which can be used permanently after being uploaded once, thus improving the user experience, reducing the complex file transfer process, facilitating file management, and achieving the effect of online management of BIM models.

[0014] 2. Small amount of data: The analysis method mentioned in the present invention solves the problem of large amount of BIM model data. The model file is extracted through the public method provided by the revit software, and calculation and analysis are performed through a specific mathematical calculation method. The data is output and stored in a customized data format, and the huge amount of data is extracted and refined, and data useful for the actual production environment is analyzed, and useless information is removed, thereby improving the user's efficiency in using the BIM model, and effectively enhancing the user experience, which plays a significant role in the popularization and application of BIM technology.

[0015] 3. Convenient application: The present invention solves the technical limitations of the previous BIM model in terms of display. In the past, BIM models could only be loaded and displayed on supported software. Through the present invention, the BIM model is converted into a gltf format file that can be loaded by the browser. In this way, the BIM model can be loaded and viewed in the browser, thereby realizing the Web online display of the BIM model. From the perspective of the actual production environment, the application value of BIM technology is greatly improved, and BIM technology can be quickly popularized and promoted in multiple industries such as the construction engineering industry, engineering manufacturing industry, and computer information technology industry.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the description of the present invention, it is necessary to understand that the terms “resume transmission”, “model conversion”, “data parsing”, etc. are specific technical means in the model parsing process, which are only used to facilitate the description of the specific processes and steps of the present invention, and therefore cannot be understood as limitations on the present invention.

[0023] like Figure 1 As shown, the cloud-based BIM model data parsing method of the present invention includes the following steps:

[0024] (10) Model file acquisition: Obtain BIM model files from the cloud and add them to the data analysis queue;

[0025] The data parsing queue is processed in the first-in-first-out principle and is processed in the order of submission time.

[0026] (20) Model file logic processing: performing corresponding logic processing according to the model type corresponding to the BIM model file;

[0027] The model types corresponding to the BIM model file include civil engineering model and electromechanical model.

[0028] like Figure 2 As shown, the (20) model file logic processing steps include:

[0029] (21) Civil engineering model logic processing: When the model type corresponding to the BIM model is a civil engineering model, extract room information, generate room files, convert file formats, and upload them to the server;

[0030] like Figure 3 As shown, the (21) civil engineering model logic processing steps include: (211) room information extraction: by using the secondary development application program interface provided by Revit, the room information is extracted and synchronized to the basic database table, and the parsing status and parsing time are synchronized at the same time;

[0031] (212) Room file generation: Generate a custom format file that can directly load room information based on the BIM model, upload it to the server, and synchronize the generation status and generation time;

[0032] (213) File format conversion: Convert the BIM model into a gltf format file, upload it to the server, and synchronize the conversion status and generation time.

[0033] (22) Mechanical and electrical model logic processing: When the model type corresponding to the BIM model is a mechanical and electrical model, extract the equipment information, generate equipment files, parse the model filter data, convert the file format, and upload it to the server;

[0034] like Figure 4 As shown, the (22) electromechanical model logic processing step includes:
