Three-Dimensional Visual Monitoring System of Airport Runway Based on Digital Twins

为响应2020年民航局发布的《推进四型机场建设行动纲要》中的推动机场转型升级的要求,并且为了解决传统人工机场跑道监测效率低下且无法做到对机场跑道的全方位实时监测和监测数据的实时互通等问题,结合数字孪生技术对机场跑道监测架构进行设计,通过运用三维可视化技术对机场跑道传感器和监控器汇总到平台的数据进行处理并在虚拟模型中实现映射,运用数字模型对机场三维模型进行还原,对机场三维模型的轻量化进行研究,同时通过光纤传感对飞机的轨迹进行实时定位和映射,生成虚拟孪生体,把机场跑道的实时状态映射到虚拟空间上,实现数字孪生的虚实相映。从而做到对机场跑道的多维度观测、全量数据分析和可视化要求,直观动态的展示机场跑道的实时状态。

In response to the requirements of promoting the transformation and upgrading of airports in the Action Outline for Promoting the Construction of Four Types of Airports issued by the Civil Aviation Administration in 2020,and in order to solve the problems of low efficiency of runway monitoring in traditional artificial airports and the inability to achieve all-round real-time monitoring of airport runways and real-time communication of monitoring data,in this paper,the airport runway monitoring architecture is designed based on digital twinning technology.Through the use of 3D visualization technology,the airport runway sensors and monitors are summarized into the platform data for processing and mapping in the virtual model.The digital model is used to restore the airport 3D model,and the lightweight of the airport 3D model is studied.At the same time,the aircraft trajectory is real-time located and mapped through optical fiber sensors.The virtual twin is generated to map the real-time state of the airport runway to the virtual space,and realize the virtual and real mapping of the digital twin.So as to meet the requirements of multi-dimensional observation,full data analysis and visualization of the airport runway,and visually and dynamically display the real-time status of the airport runway.
