基于眼动数据和PERCLOS的管制员疲劳状态研究

Study on Fatigue and Eye Movement Data Controllers Based on PERCLOS

空中交通管制员在确保空中交通管制安全和效率中起着重要的作用,管制员的工作负荷是影响航空安全和管制效率的重要因素之一。随着航空业的快速发展,我国空中交通流量不断增大,管制员的工作负荷亦随之增加,进而管制员的疲劳状态也随之增多,导致工作效率变差,有效的实时监控管制员疲劳状态,保证飞行安全正变得日益重要。文章提出基于眼动数据的管制员疲劳状态监测,通过收集管制员管制过程中眼动追踪的眼动数据,分析注视状态极其瞳孔变化、眨眼时间、眨眼频率等指标结合PERCLOS方法来评测管制员的疲劳状态。为管制员的工作负荷研究提供数据和手段支持。

Air traffic controllers to ensure that plays an important role in the safety and efficiency of air traffic control, the controller work load is one of the important factors that affect aviation safety and the efifciency of control. With the rapid development of the aviation industry, the increasing air trafifc lfow in China, controller work load also increases and the fatigue state of the controller also increases, resulting in work becomes less efifcient and effective real-time monitoring controller fatigue state to ensure lfight safety is becoming more and more important. The author puts forward based on eye movement data controller fatigue condition monitoring, through the collection of the controllers in the process of eye tracking eye movement data, analysis attention condition extremely pupillary changes, blink time, blinking frequency index combining PERCLOS method to the fatigue state of the evaluation of the controllers. Provide data and method support for the research of controller workload.
