摘　　要：为探索检测管制疲劳指标的性能,利用模拟塔台管制软件和眼动仪搭建实验平台进行实验,设计了扫视速度、注视点数、平均注视时长、扫视幅度、闪光融合频率和眼闭合时间比例(percentage of eyelid closure time,PERCLOS)6项指标;并利用卡罗林斯卡嗜睡量表对主观疲劳程度进行评定。通过疲劳前后各项指标的差异显著性,从与疲劳的相关性、受试者工作特征曲线两个方面进行分析,分别评估了指标单项检测和联合检测管制疲劳的性能。研究结果表明:扫视速度、注视点数、闪光融合频率和PERCLOS指标与疲劳呈中度及以上显著相关;其检测管制疲劳的性能在中等及以上水平,可以作为检测管制疲劳的参考指标。指标联合检测管制疲劳的性能要优于单项检测,可以更为准确地检测管制疲劳。所有指标中PERCLOS指标是检测管制疲劳指标中性能最好的指标。In order to explore the performance of index on air traffic controllers fatigue detection,an experimental platform was constructed based on the simulated tower control software and eye tracker.6 single indicators including saccade speed,fixation points,fixation duration mean and average saccade length,critical flicker fusion frequency and PERCLOS were developed.And subjects subjective sleepiness scales were collected by using Karolinska sleepiness scale.Then the difference significance of each indicator before and after fatigue was conducted.And the detection performance of combined detection and single assay were evaluated from the aspects of their correlation with fatigue and receiver operating characteristic curve.The results show that saccade speed,fixation points,critical flicker fusion frequency and PERCLOS are medium and medium above significantly correlated with fatigue.And through the analysis of receiver operating characteristic curve,their performance on detecting fatigue is at moderate and above levels and can be used as reference indicators to detect air traffic controllers fatigue.The detection performance of combined detection is better than single assay,they can be more accurately detect air traffic controllers fatigue.Among all the indicators,PERCLOS is the best performers in detecting fatigue.
