摘要
为了监测管制员在执勤期间的疲劳风险,首先将管制员的闪光融合临界频率(CFF)作为评估管制员疲劳程度的指标,并结合卡罗林斯卡嗜睡量表(KSS)评分,建立人的疲劳程度与CFF值之间的关系方程;然后定义疲劳指数,用以反映管制员的疲劳状态,进而提出基于CFF的管制员疲劳评估方法;最后通过36 h睡眠剥夺状态下的模拟管制试验,采集5名被试CFF和模拟管制成绩,分析疲劳指数与模拟管制成绩的变化关系。结果表明:4名被试的疲劳指数呈周期性变化,一名被试的疲劳指数先下降然后一直上升,每名被试的疲劳指数与其模拟管制成绩呈负相关性;随着睡眠剥夺试验的进行,5名被试的疲劳指数均值呈上升趋势,模拟管制成绩均值呈下降趋势。
In order to monitor fatigue risks of air traffic controllers during their duties,with their CFF as an index to evaluate fatigue degree,a relationship equation between fatigue degree and CFF was established based on KSS scale score.Then,fatigue indexes were defined to reflect fatigue state,and a fatigue evaluation method based on CFF value was established.Finally,through a 36-hour simulated control experiment under state of sleep deprivation,CFF and simulated control scores of five subjects were collected,and relationship between the indexes and simulated control scores was analyzed.The results show that the fatigue index of four subjects change periodically,while that of the other one decrease first and then increase all the time.And there is a negative correlation between fatigue index of each subject and their simulated control performance.With the progress of sleep deprivation experiment,the indexes of five subjects present an upward trend,while the simulated performance shows a downward trend.
