The invention belongs to the technical field of flight control, and particularly relates to an aircraft air collision avoidance hierarchical decision method and system. The method comprises the following steps: step 1, acquiring relative position information of threatening aircrafts, performing conflict detection according to the relative position information to obtain a collision warning sign, and sequencing the priorities of the threatening aircrafts; step 2, acquiring state information of the threat aircraft with the highest priority, determining a threat type according to the state information, and acquiring a 9 o'clock direction mark NF and a threat resolution mark RF of the threat aircraft with the highest priority; 3, referring to an air rule, and generating a decision suggestion for avoiding maneuver according to the collision warning sign and the threat type; and step 4, generating an evasion maneuver trajectory profile according to the 9 o'clock direction mark NF of the threat, the threat resolution mark RF and the decision suggestion.

    本申请属于飞行控制技术领域,特别涉及一种飞机空中防撞分层决策方法及系统。方法包括:步骤一、获取威胁飞机的相对位置信息,根据所述相对位置信息进行冲突检测得到碰撞警告标志,并对各个威胁飞机的优先级进行排序;步骤二、获取优先级最高的威胁飞机的状态信息,根据所述状态信息确定威胁类型,以及获取优先级最高的威胁飞机的威胁位于9点钟方向标志NF以及威胁解决标志RF;步骤三、参考空中规则,根据所述碰撞警告标志以及所述威胁类型生成规避机动的决策建议;步骤四、根据所述威胁位于9点钟方向标志NF、所述威胁解决标志RF以及所述决策建议生成规避机动轨迹剖面。
