A method and system for automatically correcting physical connections of electromechanical systems across files

Abstract

A method and system for automatically correcting physical connections of an electromechanical system across files is provided, which includes obtaining all free connector information, the informationof each free connector ci including a connector ID, center point spatial coordinates (xi, yi, zi), and a direction vector (vi); Obtaining an allowable distance error d and a directional included angleerror theta of connector matching; Establishing a three-dimensional spatial bounding box including all of the free connectors according to the spatial coordinates of the free connectors; Dividing thethree-dimensional spatial bounding box into small cubes of equal side length a (a>d); Computing free connector pairs in a cube and adjacent cubes that can be interconnected; Wherein the free connector refers to a connector with one end connected to a pipe or device and one end not connected. Thus, the problem that the free connector cannot be automatically corrected in the cross-file building information model is solved, the matching complexity is reduced, and the correction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of building information, in particular to a method and system for automatically correcting the physical connection of electromechanical systems across files. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is a three-dimensional digital description of building entities. It has been widely used in the construction phase of building electromechanical systems, but there are still no actual cases of successful application in the operation and maintenance phase. In the construction phase, during the creation of the BIM model, due to the large file volume, in order to avoid problems such as low modeling efficiency, the BIM models of different floors are often stored in different files, resulting in the lack of physical connections of the mechanical and electrical systems located in different files. For example, a pipeline running through layers 1 to 2 is divided int...

AI Technical Summary

Problems solved by technology

Therefore, the problem of lack of physical connection of electromechanical systems across files has not been paid attention to and solved

However, the number of free connectors in the BIM model is large, often exceeding 10,000, making it difficult to manually associate

In addition, during layered BIM modeling, due to human errors such as the pipes on the upper and lower floors may not pass through the floor correctly or the direction of the pipes is not completely accurate, resulting in automatic matching of free connectors, it is difficult to correct the physical connection

At present, the application of BIM in the operation and maintenance stage is still in its infancy, and no public related devices and methods have been found, which can solve the problem of cross-file physical connection repair of electromechanical systems in the process of transforming the construction BIM model into the operation and maintenance BIM model
