The invention discloses an airport group traffic flow strategic conflict alarm method under collaborative operation. The method comprises the following steps: acquiring historical trajectory data, flight plan data, flight plan data and airport group airspace information in advance; generating a planned flight path by adopting a Gaussian mixture model; the planned flight path is matched with the airspace unit, and a daily flow matrix is constructed; a heuristic algorithm is adopted to identify aircraft conflicts, and a basis is provided for constructing traffic flow conflict indexes; three traffic flow conflict indexes including the number of conflicting aircrafts, the sorties exceeding the capacity and the number of conflicting airports are constructed; using an analytic hierarchy process to set weight parameters of the traffic flow conflict indexes; and warning conflicts based on a threshold value. The airport group traffic flow conflict is analyzed from a macroscopic level, and a comprehensive judgment basis is provided for conflict warning by constructing a traffic flow conflict index system, calculating a comprehensive index and setting a comprehensive index threshold.

    本发明公开了一种协同运行下的机场群交通流战略冲突告警方法,预先获取历史轨迹数据、飞行计划数据、航班计划数据和机场群空域信息;采用高斯混合模型生成计划飞行轨迹;计划飞行轨迹与空域单元匹配,构建日流量矩阵;采用启发式算法识别航空器冲突,为构建交通流冲突指标提供依据;构建冲突航空器数量、超过容量的架次和涉及冲突机场数量三个交通流冲突指标;用层次分析法来设定交通流冲突指标的权重参数;基于阈值的冲突告警。本发明从宏观层面分析机场群交通流冲突,通过构建交通流冲突指标体系、计算综合指数以及设定综合指数阈值,为冲突告警提供全面的判断依据。
