The embodiment of the invention discloses a conflict-free flight path planning method, device and system based on a reachable time-space domain and relates to the technical field of air traffic management and planning, thereby improving the flight safety of an aircraft in a four-dimensional flight path operation mode and reducing the workload of a controller. The method comprises the following steps: acquiring flight data of an aircraft in a cruise operation stage, and recording a real-time position and a planned flight path of the aircraft in the cruise operation stage in a three-dimensionalspace-time coordinate system; according to the planned flight path and a minimum safety interval in the three-dimensional space-time coordinate system, determining a reachable time-space domain of a main aircraft and an oblique cylinder protection area invading the aircraft; projecting the intersection of the reachable time-space domain and the oblique cylinder protection area invading the aircraft to a two-dimensional plane to obtain a set of conflict navigation modification points; and removing the set of conflict navigation modification points from the reachable time-space domain of the two-dimensional plane projected by the main aircraft to generate a conflict-free navigation modification point set and a conflict-free feasible navigation modification flight path. The method is suitablefor air traffic management.

    本发明实施例公开了一种基于可达时空域的无冲突航迹规划方法、装置及系统,涉及空中交通管理与规划技术领域,有助于提高四维航迹运行模式下航空器飞行安全性及减少管制员工作负荷。本发明包括:采集巡航运行阶段的航空器的飞行数据,并在三维时空坐标系内记录巡航运行阶段的航空器实时位置和计划航迹;根据三维时空坐标系内计划航迹和最小安全间隔,确定主航空器的可达时空域和侵入航空器的斜圆柱保护区;将可达时空域和侵入航空器的斜圆柱保护区的交集,向二维平面投影,得到冲突改航点的集合;将冲突改航点的集合从主航空器投影在二维平面的可达时空域中剔除,即可生成无冲突改航点集合和无冲突可行改航航迹。本发明适用于空中交通管理。
