AI Technical Summary

Technical Problem

Existing virtual simulations of unmanned tower cranes suffer from problems such as scene distortion, rough simulation, and missed risk assessment. They cannot effectively integrate dynamic data, simulate the stress and motion state of equipment under dynamic changes and extreme weather conditions, and lack a multi-tower crane spatiotemporal conflict simulation mechanism.

Method used

We constructed a BIM model and point cloud data of the unmanned tower crane, established a simulation model by combining adaptive mesh technology, developed a customized physics engine for multibody dynamics simulation, combined a three-dimensional wind field model for climate coupling simulation, used an improved path planning algorithm to generate motion paths, and conducted multi-dimensional risk monitoring.

Benefits of technology

It enhances the realism and effectiveness of virtual pre-simulation, can flexibly reproduce temporary working conditions, reduce the deviation between simulation and real working conditions, monitor implicit safety indicators such as stress resonance, and support pre-simulation of spatiotemporal conflicts among multiple tower cranes.
