Collision detection method based on BIM technology

Abstract

The invention relates to a collision detection method based on the BIM technology, and belongs to the technical field of building detection. The collision detection method includes the following steps that 1) through a BIM, three-dimensional model information of a member is constructed, and the volume is calculated according to size parameters of the member; 2) the member and electrical equipment are subjected to wall-through hole leaving and subjected to collision detection, a mixed-level bounding-box collision detection method is adopted, a mixed-level tree is constructed and then is traversed, and nodes needing to be subjected to collision detection are determined according to the traversed result; 3) for geometric primitives, collision detection is carried out, and if the detection result is collision, moving is carried out to form a reasonable design scheme; 4) the construction process is simulated through the constructed model, dynamic interference existing in construction is found, the reasonable construction sequence and process are calculated, and a construction scheme is selected. According to the collision detection method based on the BIM technology, through a three-dimensional digitizing mean, the installing process is simulated, pre-designing is carried out, the problem is discovered and solved in advance, and the construction efficiency of a transformer substation is effectively improved.

Description

technical field [0001] The invention relates to a collision detection method based on BIM technology, and belongs to the technical field of building detection. Background technique [0002] In the design of indoor substations, due to the intricate distribution of cable structures, HVAC systems, water supply and drainage systems, and communication systems, it is easy to cause collisions between pipelines and structures during construction. In traditional two-dimensional design, in order to reduce collisions, designers need to have good spatial imagination and inter-professional coordination meetings to solve the problems. The main problems are as follows: [0003] (1) Manual coordination will be limited by professional skills. [0004] (2) According to the method of coordinating two-dimensional drawings, superimpose the drawings of various disciplines together, and judge whether there is space intersection according to the plan and section drawings. This method will be very ...

Problems solved by technology

[0005] (3) Multiple consultations between various disciplines are often required, which will consume a lot of manpower, and more collisions will still be found in the later construction process, which will cause rework and delay the progress of the project

However, the design software itself still needs to be perfected and optimized, and the digital process has yet to be formulated. Some basic work includes the content contained in the digital design technology system, relevant regulations and specifications, and the content, depth, and method of digital transfer, and the life cycle management of power transmission and transformation projects. Requirement interface standards urgently need to be formulated
