Method for constructing real scene model collaborative design platform of railway engineering

Abstract

The invention relates to a method for constructing a real scene model collaborative design platform of railway engineering. Railway and urban rail transit projects are distributed in a strip shape, engineering data are large, numerous professions are involved, and therefore, the efficient and stable collaborative design platform needs establishing. According to the method, the strip-shaped continuous three-dimensional real scene model is established along the whole range of the project, and fusion processing is performed on all professional three-dimensional building information models (BIM) and the three-dimensional real scene model. Under the management mode of a distributed database, management is performed on a global data base of the three-dimensional real scene model collaborative design platform and special databases of all professional BIM design platforms which only transmit upstream data and downstream data involved in collaborative design and generated BIM three-dimensional design results onto the three-dimensional real scene model collaborative design platform. By means of the method, the strip-shaped project information model along the whole range of the project is established, all professional interactive data are integrated into a continuous three-dimensional real scene, and collaborative design is achieved.

Description

technical field [0001] The invention belongs to the technical field of informationization of railway and urban rail transit construction, and in particular relates to a construction method of a collaborative design platform for a real scene model of railway engineering. Background technique [0002] BIM (Building Information Modeling, Building Information Modeling,) refers to the use of digital technology to express the geometric, physical and functional information of a building project (now generally referred to as an engineering project), and to support the project design, construction, operation and management of the entire life cycle technology, method or process. BIM has five characteristics of visualization, collaboration, simulation, optimization, and drawing. It enables the communication, discussion, and decision-making of engineering projects in the process of design, construction, and operation to be carried out in a visualized state; it can not only simulate des...

Problems solved by technology

[0006] 2. Huge number of projects and massive data:

With the advancement of technology and the improvement of construction standards, these majors not only have high technical requirements, but also require close cooperation and collaborative design among multiple disciplines, and there are many parallel and cross operations.

[0010] 4. There are large differences in project attributes, and it is not easy to develop general-purpose software:

[0012] 5. There are "information islands" among majors, and most of the current software does not have BIM interface:

With the deepening of informatization construction, each design major is also gradually improving its own professional database, and strengthens the management and maintenance of data, but it does not plan and coordinate from an overall height, making the degree of informatization of each major more and more serious. Deeper, the phenomenon of "information islands" among majors is more serious

In addition, most of the auxiliary design software being used by various majors did not consider the interface with BIM software when developing
