The invention discloses a terminal area airspace conflict detection and resolution algorithm based on flight flow pre-sorting. The algorithm comprises the following steps: 1, determining a flight planset; 2, carrying out flight flow pre-sorting; 3, carrying out pre-sorted flight flow traversal, and if the flights in the sequence are flights to be added into a simulation terminal area airspace forconflict detection and resolution, carrying out the step 4; 4, carrying out flight point-passing traversal, if terminal area airspace points which are not traversed do not exist in the point-passingsequence of the flight, indicating that the flight has finished conflict detection and resolution of the whole path, and carrying out the step 3; or otherwise, carrying out conflict detection and resolution on points in the flight point-passing sequence, and carrying out the step 5; and 5, carrying out conflict detection and resolution. According to the invention, flight flows are sorted in advance, and flight conflict detection is realized through a point-passing time window on the basis of flight trajectories; conflict resolution is carried out on the premise of flight deduction process backtracking; and in order to be close to the actual control purpose, simulation deduction based on service requirements can be achieved, and the result is real and credible.

    本发明公开一种基于航班流预排序的终端区空域冲突探测与解脱算法,包括:1.确定航班计划集合;2.航班流预排序;3.预排序航班流遍历,若序列中的航班为即将加入仿真终端区空域进行冲突探测与解脱的航班为,执行步骤4;4.航班过点遍历,若该航班的过点序列中不存在尚未遍历的终端区空域点,则表示该航班已完成全路径的冲突探测与解脱,执行步骤3;否则,对于航班过点序列中的点进行冲突探测与解脱,执行步骤5;5.冲突探测与解脱。本发明通过对航班流预先排序,又以航班轨迹为基础,通过过点时间窗实现航班的冲突探测;以航班推演过程回溯为前提进行冲突解脱;以贴近实际管制目的,能够实现基于业务需求的仿真推演,使结果真实可信。
