摘要:

未来ATC 的发展是以航迹为对象从管制意图出发并配备相应的间隔,实时动态地掌握航空器与航空器之间的位置;依据美国Next-Gen 空中交通管理系统的4D航迹应用规划,针对4D航迹的数据内容借助UML和XML Schema 完成了4D航迹的数据建模,并给出了4D 航迹互操作模式下的发布订阅模型;通过对该模型的QoS渊quality of service冤数据同步的分析,可有效地规范4D航迹互操作模式下的数据交换。

关键词: 4D航迹, 数据互操作, QoS机制

Abstract:

The future development of ATC is to track the flight object which is equipped with the appropriate interval considering the control of intention,then we can real-time dynamically master the position between the aircraft. Based on the 4D trajectory application plan of the American Next-Gen air traffic management system,the paper use the UML and XML Schema to design a conceptual and logical data model of 4D trajectory,it proposes a model of publish and subscribe service in the interoperability. By analysising the model of QoS(quality of service)data synchronization,it can effectively regulate the 4D trajectory interoperable data exchange.

Key words: 4D trajectory, data interoperability, QoS structure
