The invention provides a complex deep foundation pit monitoring system and method based on a BIM + 3D laser scanning technology. The monitoring system comprises a 3D laser scanning system, a BIM system and a monitoring system. The 3D laser scanning system and the BIM system are respectively connected with the monitoring system; the 3D laser scanning system comprises a 3D laser scanner and is usedfor acquiring a real point cloud model of the deep foundation pit; the BIM system comprises a drawing import unit which is used for reading drawing information of the deep foundation pit and obtaininga three-dimensional BIM model of the deep foundation pit; the monitoring system is used for conducting real-time remote monitoring on the deep foundation pit on site and comprises a cloud platform system and an early warning system. And the cloud platform system is connected with the 3D laser scanning system, the BIM system and the early warning system. According to the method, the optimized BIMsystem and the 3D laser scanning technology are adopted for modeling, a web platform is used for achieving the visualization function of the model, and real-time monitoring and remote monitoring of the complex deep foundation pit are achieved.

Description

technical field [0001] The invention relates to a building management system, in particular to a complex deep foundation pit monitoring system and method based on BIM+3D laser scanning technology. Background technique [0002] Deep foundation pit engineering is a project with a high incidence of accidents in construction engineering, and the risk is relatively high. All localities also attach great importance to the safety supervision of foundation pit engineering, but foundation pit engineering accidents still occur from time to time. The main reason for these accidents is that the main responsible units of all parties involved in the construction of the project did not effectively supervise every link in the whole process of deep foundation pit engineering from survey and design to foundation pit backfill. [0003] With the current development level of BIM, Internet, public cloud, mobile client and other technologies, it is completely possible to obtain real-time and accur...

Problems solved by technology

[0007] In view of the technical problems that the traditional algorithm used in the current deep foundation pit monitoring system has not been optimized and the 3D laser scanning model cannot be displayed through the web platform, this invention proposes a complex deep foundation pit monitoring system based on BIM+3D laser scanning technology. Use the optimization algorithm to carry out lightweight processing on the BIM model and point cloud model, and synthesize the 3D deep foundation pit model; use the web platform to display the 3D deep foundation pit model, realizing the visualization of the BIM model; transmit the on-site monitoring data to the web platform , so that the monitoring data can be viewed in the 3D deep foundation pit model in real time, and the danger source can be found in time and dealt with accordingly
