Construction management system and management method based on 5g video and bim

Abstract

The invention discloses a construction management system based on 5G video and BIM and a management method thereof. The user compares the construction site scene captured by the physical camera in real time with the BIM of the same viewing angle and similar time axis, so that the user can Intuitively observe the difference between the real progress and the plan of the construction project, as well as the difference between the real construction situation and BIM; users can browse the BIM information and construction design parameters in real time by clicking on the BIM components in the same perspective as the real perspective, and get the current and next construction process. Design information needed in the BIM; users can trace the similarities and differences between the real construction situation at this point in time and BIM through image tracing. The present invention integrates 5G remote video monitoring and BIM digital collaborative traceability, realizes real-time comparison of design drawings and actual construction results and control of details, and plays the role of timely deviation correction and project early warning. Backfilling the BIM with the construction data related to the BIM components is conducive to the retrospection of the project and records the construction process in a digital form.

Description

technical field [0001] The invention relates to a construction supervision and management method 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; the abbreviation of English Building Information Modeling) technology, BIM has gradually radiated 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 whole life cycle of the building into a unified model, break through the business segmentation in the design, construction, operation and maintenance stages, solve the problem that data cannot be shared, and realize integration , the whole process application. [0003] At present, the use of BIM and remote video surveillance systems to supervise and manage co...

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.
