    摘要:

    在机场自治化运行条件下,对于场面运行环境的感知是制约机场实现自治化运行的一个关键因素,而机场场面交通运行过程中对于场面滑行资源占用情况是构建完整的场面运行环境的关键步骤,本文首先以机场场面滑行过程为研究对象,构建了机场场面滑行过程的本体模型,基于机场的场面路网结构,对路网中的滑行路径进行划分,建立了以路网节点与节点连接关系为基础的“节点-边”模型,同时以本体模型为基础,定义了场面路网的动静态属性作为路网节点的基本属性,在此基础上,以路网节点为研究对象,将航空器场面滑行过程中的存在的多种冲突场景以路网节点的动态属性进行模型表达,从而实现了航空器滑行过程在路网节点上的动态表示。以航空器动力学模型生成的速度数据为基础,设计了在航空器冲突场景下的飞行区场面滑行资源动态图的可视化表示,试验结果表明,该模型可以很好的表示场面运行过程中的冲突场景和无冲突运行过程。可以增强场面交通参与者对飞行区场面滑行资源占用状况的全域感知能力。

    Abstract:

    Under the condition of airport autonomous operation, perception of the operational environment is a crucial factor constraining the realization of autonomous airport operations. In the process of airport surface traffic operation, understanding the utilization of surface movement resources is a key step in establishing a comprehensive operational environment. This study first focuses on the surface movement process at airports and constructs an ontology model for airport surface movement processes. Based on the structural layout of the airport surface road network, the movement paths are divided, and a "node-edge" model based on the connection between network nodes is established. Meanwhile, building upon the ontology model, dynamic and static attributes of the surface road network are defined as the basic properties of network nodes. With network nodes as the research object, various conflict scenarios existing in aircraft surface movement processes are modeled based on the dynamic attributes of network nodes, thus achieving a dynamic representation of aircraft movement processes at network nodes. Using speed data generated by aircraft dynamics models as a basis, a visualization representation of dynamic graphs of surface movement resource utilization in the presence of aircraft conflict scenarios is designed. Experimental results demonstrate that the model effectively represents both conflict and conflict-free scenarios in surface operations. This enhances the overall perception of surface movement resource utilization among participants in airport surface traffic.
