为预防鸟撞事故,根据事故发生过程和开放系统的熵演变过程有很大相似性这一特点,采用信息熵理论解释事故发生过程,进而建立鸟撞事故发生和预警的动力学模型,揭示引发事故的主要原因和预防事故的对策。在此基础上,采用基于熵的综合评价方法,对造成事故的多个因素进行对比分析和综合评价,得出鸟撞事故中飞行时间(季节和昼夜2个因素)、飞行高度、飞机的结构、遭遇的鸟类和发生区域等5大类共6个因素的熵值。结果表明,飞鸟种类的熵值最大,为0.410 6;其次是飞机结构因素。因此,预防鸟撞事故应该从飞鸟控制和飞机结构设计着手。
In order to prevent bird collision, based on the characteristics of the similarity between the accident occurrence process and the entropy evolution of open system, the information entropy theory is used to explain the process of the accident and then the dynamic model of bird collision and warning is established. Main Causes of Accidents and Countermeasures to Prevent Accidents. Based on this, a comprehensive evaluation method based on entropy is used to compare and comprehensively evaluate the multiple factors causing the accident, and the flight time (two factors of season, day and night), the height of the flight, the structure of the aircraft , Encountered birds and occurrences of five major categories of total 6 factors entropy. The results showed that the species of birds had the highest entropy value of 0.410 6, followed by the aircraft structure. Therefore, the prevention of bird collisions should start with bird control and aircraft structural design.
