摘　　要：针对智慧飞行区运行建设研究中,数字孪生的服务应用模块仍然存在数字模型与物理空间缺少交互、功能缺乏应用的问题,依托数字孪生技术对飞行区运行多要素进行物理映射和仿真,构建4层数字孪生基本体系架构;通过数据实时传输,实现物理空间与数字孪生模型、物理对象与虚拟目标之间的虚实映射和状态更新;结合孪生域的数据仿真迭代实现物理域的实时决策,为运行服务对象提供航空器实时状态反馈、指令风险评估等服务。在此架构内分析了五大关键技术的可行性和必要性,采用多种工具对飞行区运行三维空间结构进行建模,在结合航空器运行指令的场面风险评估仿真和可视化对目前的飞行区运行数字孪生技术成熟度进行评价的同时,验证了构建数字孪生运行飞行区的可行性。In the research on the operation and construction of the smart flight zone,it is currently focused on the digital twin service application module.There are still problems of lack of interaction between the digital model and the physical space,and lack of application of functions.In view of the existing problems,a four layer basic architecture of flight zone operation digital twin was built relied on the physically mapping and simulation of digital twin technology to multi-elements of flight zone operation.Through the real-time data transmission,the virtual and real mapping and status update between physical space and objects,digital twin models and virtual targets were realized.Combined with the data simulation iteration in the twin domain,the real-time decision-making in the physical domain was realized,which provided pilots and controllers with real-time aircraft status feedback,command risk assessment and other services.Within this framework,the feasibility and necessity of five key technologies were analyzed,and the three-dimensional spatial structure of flight zone operation was modeled through terraexplorer,Java and other tools,and the simulation and visualization of surface risk assessment based on aircraft operation instructions were carried out.The maturity of the current digital twin technology of flight zone operation was evaluated,and the feasibility of building a digital twin operation flight zone was verified.
