技术领域technical field
本发明涉及民用航空技术领域，尤其是涉及一种民航飞行操作安全校验方法及其装置。The invention relates to the technical field of civil aviation, in particular to a civil aviation flight operation safety verification method and device thereof.
背景技术Background technique
民用航空的安全飞行依靠飞行器准确的依照空中交通管制的指令进行飞行。目前空中交通管制的指令主要依靠无线电进行语音管制。由于无线电干扰、方言等因素的存在，以及飞行员的错误操作可能性的影响，难免出现飞行员的操作不符合空中管制员指令的情况。本发明在于依靠大数据语义识别及图像识别技术，对空中管制指令与飞行员的操作进行识别比对，在飞行员操作出现错误的情况下，进行声光提示告警，以提高飞行的安全性。The safe flight of civil aviation depends on the accurate flight of aircraft in accordance with the instructions of air traffic control. At present, air traffic control instructions mainly rely on radio for voice control. Due to the existence of radio interference, dialect and other factors, as well as the influence of the possibility of pilot's wrong operation, it is inevitable that the pilot's operation does not comply with the air controller's instructions. The present invention relies on big data semantic recognition and image recognition technology to identify and compare air traffic control instructions and pilot operations, and to perform sound and light warnings in case of errors in pilot operations, so as to improve flight safety.
