Railway four-electricity engineering BIM information model creation method based on IDM process

Abstract

The invention relates to a railway four-electricity engineering BIM information model creation method based on an IDM process. The method comprises the steps: arranging the related information of a railway station front specialty, and carrying out the datamation of information affecting the creation of a four-electricity specialty BIM information model; classifying and sorting related equipment according to the four-electricity IFD, digitalizing equipment information, and establishing dictionary data of all professional equipment of four electricity; establishing a project information data structure; inputting a design result of the four-electric engineering into a four-electric equipment arrangement table; and calculating, analyzing and establishing a four-electric equipment BIM model byutilizing the data preparation in the above steps and an interface method of three-dimensional modeling software. According to the method, the creation of the data-driven four-electric engineering BIMinformation model based on the IDM scene can be quickly realized, and the BIM information model is quickly updated after basic data modification and four-electric design modification, so that the railway four-electric BIM engineering forward design capability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of railway four-power BIM, in particular to a method for creating a BIM information model of a railway four-power project based on an IDM process. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) technology is profoundly affecting the construction industry, bringing a new revolution to the industry. BIM is the transformation of building information technology from two-dimensional expression based on points, lines and surfaces to three-dimensional shape and attribute information expression based on objects. The core of BIM lies in information. In addition to the description of 3D geometric information and topological relationship of engineering objects, it also includes a complete description of engineering information. Ongoing use of information databases. The railway four-power project refers to the railway construction project mainly including four professi...

Problems solved by technology

[0005] Under the IDM process system, the requirements for data integrity, inheritance, scalability, and automation level are improved, but the current method is that designers use 3D modeling software to manually insert the four electrical equipment into the 3D space one by one, and manually add various data. This method is time-consuming and labor-intensive, and the efficiency is very low. The positioning of the equipment in the three-dimensional space is not fast enough and accurate, and consumes a lot of manpower and material resources.

This method cannot meet the data requirements in the entire life cycle of the four-electric equipment based on the IDM system, and the data integrity, scalability, and automation level cannot meet the requirements of railway construction and operation stages and the requirements of railway informatization

[0006] Due to the lack of means to detect, evaluate, and certify the BIM technology and results of the railway four-power project, the creation and application of the BIM model of the railway four-power project cannot be checked for compliance, making it difficult for the research and application of BIM technology to form a healthy development
