BIM information model creation method for railway four-power project based on idm process

Abstract

The invention relates to a method for creating a BIM information model of a railway four-power project based on an IDM process. The steps are as follows: sorting out relevant information in front of a railway station, digitizing information that affects the creation of a BIM information model for a four-power specialty; sorting out according to the four-power IFD Relevant equipment, digitize equipment information, establish dictionary data of various professional equipment of Sidian; establish project information data structure; enter the design results of Sidian project into Sidian equipment layout table; use the above steps for data preparation and the interface of the 3D modeling software itself Methods Calculate, analyze and establish the BIM model of four electric equipment. This method can quickly realize the creation of the BIM information model of the four-power project based on data in the IDM scenario, and quickly update the BIM information model after the basic data is modified and the four-power design is modified. towards design capabilities.

Description

technical field [0001] The invention relates to the technical field of railway four-electricity BIM, in particular to a method for creating a BIM information model of a railway four-electrical project based on an IDM process. Background technique [0002] 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 point, line and surface to three-dimensional form and attribute information expression based on object. The core of BIM lies in the information (Information), in addition to the description of the 3D geometric information and topological relationship of the engineering objects, it also includes the complete description of the engineering information. Continuously utilized information database. The railway four-power project refers to the railway construction project mainly including ...

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
