Research On Abnormal Behavior Recognition Ability Of Aviation Security Personnel Based On Information Processing Model

In recent years,with the improvement of the civil aviation industry,the number of flights and the size of the fleet have continued to expand,emergencies in the cabin have also increased.How to identify abnormal behaviors as soon as possible and take effective measures has become the key points in the research of civil aviation.The current research on abnormal behavior recognition is only limited to the recognition of abnormal behavior based on computer vision,and considering the internal environment of the cabin,it is impossible to recognize abnormal behavior in the cabin based on computer vision.Aviation security personnel,as important personnel in safeguarding air safety,shoulder the responsibility of identifying abnormal behaviors in the cabin and ensuring the safety of passengers and aircraft.Therefore,it is of great significance to take deep research on the ability of aviation security personnel to identify abnormal behaviors to improve their ability to identify abnormal behaviors and make some reference comments.Based on the information processing model,combined with the environment and content of the aviation security personnel’s work,the process of the aviation security personnel on identifying abnormal behaviors is divided into three stages,namely the information input stage,the information processing stage and the information output stage.Through the analysis of the information processing of aviation safety personnel at various stages,it was found that reasoning ability,memory ability and attention quality will affect the processing and recognition of abnormal behaviors of aviation safety personnel.Furthermore,20 air security major students who participated in the internship and 20 non-air security college students were selected as subjects,and e-prime software and eye movement instrument were used to conduct simulated abnormal behavior recognition experiments.Finally,we analyzed the influence of experience level,reasoning ability,memory ability,attention quality and search strategy on the ability of aviation safety personnel to recognize abnormal behavior.By grouping the abnormal behavior recognition ability,it is found that the fixation duration of the high abnormal behavior recognition ability group is longer than that of the low group;the average saccade distance of the high abnormal behavior recognition ability group is shorter than that of the low group;the fixation point of the high abnormal behavior recognition ability group is more scattered compared with Low grouping.The results found that: experience level will significantly affect the ability of aviation safety personnel to recognize abnormal behaviors,aviation safety personnel with high experience levels have strong ability to recognize abnormal behaviors;reasoning ability has a significant impact on the ability of aviation safety personnel to recognize abnormal behaviors,and Aviation safety personnel with strong reasoning ability have strong ability to recognize abnormal behaviors;memory ability has a significant impact on the ability of aviation safety personnel to recognize abnormal behaviors,aviation safety personnel with strong memory ability have strong ability to recognize abnormal behaviors;attention quality will significantly affect aviation safety personnel’s ability to recognize abnormal behaviors,aviation safety personnel with high-quality attention have strong ability to recognize abnormal behaviors.By studying the ability of aviation security personnel to recognize abnormal behaviors and analyzing its influencing factors,it provides some suggestions for improving the ability of aviation security personnel to recognize abnormal behaviors,and provides a theoretical basis for the selection and training of aviation security personnel.
