The invention relates to a space-time conflict detection method for a planned route of an aircraft, and belongs to the technical field of flight safety evaluation. The method comprises the following steps of: dividing a flight area into a series of discrete grid units by adopting a space grid division method, and performing discrete division of time at the same time to form a space-time integrated space-time coding system; expressing a planned route as a grid unit set, calculating a grid code set of a buffer area according to the early warning distance, and judging whether impassable grids exist in the buffer area according to quantitative expression of field environment elements and space-time coding of object environment elements; and judging whether the space-time grid codes of the safe flight buffer area and the object environment element grid codes are in space-time intersection or not, so as to realize the safety degree evaluation of the planned route of the aircraft. The method does not need complex space operation, can be realized only through simple grid coding operation, greatly reduces the calculation amount, and improves the detection efficiency of the space-time conflict of the planned route.
本发明涉及一种飞行器计划航线的时空冲突检测方法,属于飞行安全评估技术领域。本发明采用空间网格剖分方法将飞行区域剖分为一系列离散的网格单元,并同时进行时间的离散剖分,形成时空一体的时空编码体系;将计划航线表示为网格单元集合,并根据预警距离计算缓冲区的网格编码集合,根据对场环境要素量化表达以及对对象环境要素时空编码,判断缓冲区内是否存在不可通行的网格,并判断安全飞行缓冲区时空网格编码与对象环境要素网格编码是否时空相交,以此实现飞行器计划航线的安全度评估。该方法不需要复杂的空间运算,只需简单的网格编码运算就可实现,大大减少了计算量,提高了计划航线时空冲突的检测效率。
