深中通道管节浮运指挥系统研究

Research of Shenzhong-Link immersed tube floating transportation command system

深中通道项目沉管段管节在浮运安装过程中操控性较差,易出现失控乃至搁浅等事故。针对管节浮运过程中的位置服务进行了研究,综合采用定位精度实时评估、网络化分布式实时导航定位数据处理和BIM、三维激光扫描结合应用等方法,为管节浮运全过程提供无缝高精度位置服务和可视化工作拖轮指挥调度。文章分析了深中通道管节浮运指挥系统架构,详细介绍了硬件设备管理、数据融合计算、二维平面和三维立体显示等各个模块的主要功能,以及系统所涉及的关键技术。

The immersed tube part of Shenzhong-Link is one of the most difficult construction projects in the world currently.The maneuverability of immersed tube during floating transportation is very poor,and it is easy to get out of control,even be stranded.Location service during immersed tube floating transportation was studied.Methods of real-time evaluation of positioning accuracy,network-distributed navigation&positioning data processing,BIM and 3D laser scan data integration were comprehensively used to provide seamless high-precision location service and visualized working tug dispatching for immersed tube floating transportation.This paper analyzes architecture of the command system,and introduces in detail the main functions of each module including hardware equipment management,data fusion calculation,2D and 3D display,as well as the key technologies involved in the system.
