摘　　要：为了评估临界闪光融合频率(critical flicker fusion frequency,CFF)和眼动追踪中的眼睛闭合时间占某一特定时间的百分率(percentage of eyelid closure over the pupil over time,PERCLOS)检测管制疲劳的性能,利用模拟塔台管制软件和眼动仪搭建实验平台,采集被试的CFF、PERCLOS和主观疲劳数据,从疲劳前后指标变化的差异显著性检验,与疲劳的相关性以及受试者工作特征曲线(receiver operating characteristic curve,ROC)3个方面分析探讨了CFF和PERCLOS检测管制疲劳的性能。结果表明:疲劳前后被试的CFF和PERCLOS均差异显著,且与疲劳呈高度显著相关。CFF和PERCLOS检测管制疲劳的效果分别为中等和较好,两者联合可以作为很好的管制疲劳检测指标。To evaluate the detection performance of critical flicker fusion frequency（CFF）and percentage of eyelid closure over the pupil over time（PERCLOS）on air traffic controller fatigue,an experimental platform was constructed based on tower control software and eye tracker while the CFF,PERCLOS and subjective fatigue data were collected.Based on the difference significance test of the index before and after fatigue,the Spearman correlation analysis with fatigue,and the analysis of receiver operating characteristic curve（ROC）,the performance of CFF and PERCLOS on detecting fatigue was evaluated.The results showed that the CFF and PERCLOS of the subjects before and after fatigue were significantly different,which were both significantly related to fatigue.The effect of CFF and PERCLOS on detecting air traffic controller fatigue was moderate and better,and the combination can be used as a reliable indicator for fatigue detection.
