The invention provides a low-altitude aircraft icing early warning method and system based on meteorological observation. The method comprises the following steps: acquiring historical meteorological data, historical flight data, aircraft data and icing conditions of a low-altitude aircraft in the same period; respectively establishing corresponding neural network models according to the division of the ice accretion components, and respectively training to obtain corresponding target neural network models; acquiring various data acquired by the low-altitude aircraft in real time, respectively inputting the data into the corresponding target neural network models, and outputting corresponding icing thickness and icing type; according to an output result of the target neural network model, judging whether the preset icing component reaches an early warning standard or not; if yes, first early warning is carried out; if not, weighting processing is carried out according to the icing thickness and the icing type of each icing component, and an evaluation value is obtained; judging whether the evaluation value is greater than a threshold; and if yes, second early warning is carried out, specifically, the flight risk can be effectively reduced by evaluating the icing condition of the aircraft.
本发明提供了一种基于气象观测的低空飞行器结冰预警方法及系统,该方法通过获取低空飞行器同一时期的历史气象数据、历史飞行数据、飞行器自身数据以及积冰情况;根据积冰部件的划分,分别建立对应的神经网络模型,并分别进行训练,得到对应的目标神经网络模型;实时获取低空飞行器采集各项数据,分别输入至对应的目标神经网络模型中,输出对应的积冰厚度和积冰类型;根据目标神经网络模型的输出结果,判断预设积冰部件是否达到预警标准;若是,则进行第一预警;若否,则根据各积冰部件的积冰厚度和积冰类型,进行加权处理,得到评价值;判断评价值是否大于阈值;若是,则进行第二预警,具体的,通过评估飞行器的结冰情况,可以有效降低飞行风险。
