Construction management system based on 5G video and BIM and management method thereof

Abstract

The invention discloses a construction management system based on a 5G video and BIM and a management method thereof, a user compares a construction site scene shot by a physical camera in real time with the BIM of a similar time axis at the same visual angle, so the user visually observes the difference between the real progress and plan of a construction project, and the difference between the real construction condition and the BIM is calculated; the user browses BIM information and construction design parameters in real time by clicking components in the BIM with the same visual angle as the real visual angle, and design information needed in the current construction process and the next construction process is obtained; and the user knows the difference between the real construction condition at the time point and the BIM through image tracing. According to the invention, 5G remote video monitoring and BIM digital collaborative traceability are realized, real-time comparison and detail control of a design drawing and an actual construction result are realized, and the effects of timely deviation correction and project early warning are achieved; and the construction data related to the BIM component is filled back to the BIM, so the backtracking of the project is facilitated, and the construction process is recorded in a digital form.

Description

technical field [0001] The invention relates to a supervision and management method for the construction of a construction project, in particular to a construction management system and a management method based on 5G video and BIM. Background technique [0002] With the development of BIM (Building Information Modeling; English abbreviation of Building Information Modeling) technology, BIM is gradually radiating from the application mainly in the construction stage to the application in the whole life cycle. As a carrier, BIM can integrate the engineering information, management information and resource information of the building in the whole life cycle into a unified model, break through the division of business in the design, construction, operation and maintenance stages, solve the problem that data cannot be shared, and realize integration chemical, whole-process application. [0003] At present, the use of BIM and remote video monitoring system to supervise and manag...

AI Technical Summary

Problems solved by technology

[0003] At present, the use of BIM and remote video monitoring system to supervise and manage the construction of construction projects has the following shortcomings: 1. The video monitoring system and BIM are displayed independently, and there is no unified management of on-site construction data and BIM data. The staff went to the site to investigate and test the construction situation and then compared it with the BIM data. Therefore, BIM cannot be used for timely correction and early warning of the on-site construction situation; 2. BIM only contains information such as the length, width, and height of the model, and there is no on-site construction for the model Data, BIM cannot be used to record the whole process of construction; 3. The virtual camera in the existing BIM and the real camera of the remote monitoring system cannot be linked, and the on-site monitoring and BIM can only be displayed separately, and the coordination between the monitoring screen and the BIM screen cannot be realized linkage

4. Based on BIM for construction animation production, 3D MAX and other software are used for construction animation production. The BIM virtual camera uses a fixed-focus camera, which can only zoom in on the position of the camera, and cannot rotate the camera horizontally and tilt and tilt the angle Rotation; linkage with the remote monitoring camera cannot be realized, and the staff needs to go to the site to check, and the monitoring of all aspects can be completed through the cooperation of the staff and BIM

5. Since the on-site monitoring and BIM virtual cameras use different coordinate systems, the parameters of the virtual camera and the remote monitoring camera are not uniform, and the two screens cannot be linked and can only be viewed separately, so the real-time relationship between the BIM virtual model and the scene cannot be formed.
