三维全景数字孪生技术在箱梁运架施工中的应用

Application of 3D Panoramic Digital Twin Technology in Box Girder Transportation and Erection Construction

采用三维全景数字孪生技术实现高速铁路箱梁运架施工环境及设备的虚拟映射,通过北斗定位、GIS地图、设备信息自动采集、智能推理等技术实现三维数字模型的实时驱动,达到与物理实体同步呈现的效果;各级管理人员通过数字孪生全局视角,更便捷、高效地对施工过程进行分析、预测和管控。以荆门—荆州高速铁路项目为依托,进行了实践探索,形成了高速铁路箱梁运架施工大型复杂场景的典型数字孪生应用,有效推动了传统行业与数字孪生的深度融合。

To reach the synchronous virtual effect with physical entity,the virtual mapping of the construction environment around high speed railway box girder transportation and erection and equipment was achieved by 3D panoramic digital technology,then the 3D panoramic digital models were driven in time by technology of the Beidou navigation positioning system,GIS map,equipment automatic information collection and intelligent inference.Through the digital twin global perspective,management personnel at all levels could analyse,predict and control to the work progress more conveniently and efficiently.Based on Jingmen-Jingzhou High-speed Railway project,the practical exploration was conducted,a typical digital twin application in large-scale complex scenes of high-speed rail box girder transportation and erection was formed,and the deep integration of traditional industries and digital twins was effectively promoted.
