The invention discloses a low-altitude real-time flight conflict detection and release method based on navigation rescue. According to the method, conflict detection is carried out on a planned flight trajectory of an aircraft and a predicted trajectory of a target aircraft in a spatial dimension. If the aircraft is found to have conflicts, the aircraft conflicts are divided into a two-aircraft conflict mode and a multi-aircraft conflict mode according to the number of times that the aircraft encounters the conflicts in a certain time domain; and according to whether the aircraft formation exists in the conflict related object, the two-aircraft conflict mode is divided into two-aircraft conflict and fleet conflict. The invention relates to real-time flight conflict resolution based on a Multi-Agent system. According to the invention, a conflict detection model based on a predicted flight path is provided, and a protection area model based on a visual flight interval standard is introduced to make up for the defects of the conflict detection model based on the predicted path under special circumstances. And dividing different conflict scenes according to the flight process of the conflict aircraft and the executed tasks. The method improves the safety and accuracy of actual navigation rescue, and has practical significance.

    本发明公开了一种基于通航救援的低空实时飞行冲突探测与解脱方法,将航空器的计划飞行轨迹与目标航空器的预测轨迹在空间维度上进行冲突检测。若发现航空器存在冲突,之后根据航空器在一定时间域内遭遇冲突的次数,将航空器冲突分为两机冲突、多机冲突模式;根据冲突涉及对象是否有航空器编队,将两机冲突模式分为两机冲突与机队冲突。基于Mulit‑Agent系统的实时飞行冲突解脱。本发明提出了基于预测飞行轨迹的冲突探测模型,并引入基于目视飞行间隔标准的保护区模型来弥补基于预测轨迹冲突探测模型在特殊情形下的不足。根据冲突航空器的飞行过程以及执行的任务划分不同冲突场景。本发明提高了实际通航救援的安全性与准确性,具有现实意义。
