【摘要】：在空中交通管制工作中,管制疲劳程度度量是一项需要长期研究的重要课题。实时测量管制员的疲劳程度,对航空运输系统的安全运行有重要意义。提出以眼动行为特征指标作为反映管制员疲劳程度的依据,利用faceLAB 5.0系统记录了管制员在正常状态和疲劳状态下进行管制模拟实验的眼动数据和绩效数据,分析了管制员的绩效数据与眨眼频率和瞳孔直径两种眼动指标在不同状态下的变化规律。研究发现与正常状态相比,管制员在疲劳状态下的眨眼频率增加,瞳孔直径减小。随着任务时间的增加,被试的绩效变差,眨眼频率增加,瞳孔直径减小,表明被试的工作状态从正常状态转为疲劳状态。统计分析结果说明,眨眼频率和瞳孔直径能够有效地检测管制员的疲劳状态,充分刻画不同工作时段管制员工作状态的变化,为开发实用的疲劳监测系统提供理论基础。
[Abstract]:In air traffic control, the measurement of control fatigue is an important topic that needs to be studied for a long time. It is of great significance to measure the fatigue degree of controllers in real time for the safe operation of air transportation system. According to the characteristic index of eye movement behavior as the basis to reflect the controller's fatigue degree, the eye movement data and performance data of the controller's control simulation experiment under normal and fatigue conditions were recorded by using faceLAB 5.0 system. The changes of performance data, blink frequency and pupil diameter under different conditions were analyzed. It was found that compared with the normal state, the blink frequency of the controller in fatigue state increased and the pupil diameter decreased. With the increase of task time, the performance of the subjects became worse, the blink frequency increased, and the pupil diameter decreased, indicating that the working state of the subjects changed from normal state to fatigue state. The results of statistical analysis show that the blink frequency and pupil diameter can effectively detect the fatigue state of the controller and fully describe the change of the working state of the controller during different working hours, which provides a theoretical basis for the development of a practical fatigue monitoring system.
