| 摘 要： | 疲劳驾驶是引起交通事故的重要原因之一,为预防驾驶疲劳,国内外科学家研究了多种监测驾驶疲劳的方法,其中采用心电图指标监测驾驶疲劳具有实用价值。采集6名实验对象90分钟模拟驾驶操作的心电信号,并对所选取的8个心电图指标进行分析,通过分析实验数据显示：LF、HF、LF/HF、LFNU和HFNU五个指标随着驾驶时间的增长发生显著性变化,且伴有明显波动;LF、HF和LF/HF三个指标的变化能够反映驾驶员的疲劳状态,其中LF/HF指标变化适时反映了驾驶员疲劳产生特性。因此,采用心电图指标可以对驾驶员疲劳状态进行动态监测。

| Abstract: | Fatigue driving is one of important causes which result in traffic accidents.In order to prevent from driving wearily,both domestic and foreign scientists have studied the methods for monitoring fatigue driving.We select the electrocardiogram of six experimenters in the process of driving,and analyses the selected eight electrocardiogram indicators including LF.HF.LF/HF.LFNU and HFM have occurred a significant change as the driving time goes up,moreaver,which have fluctuated obviously.The change of LF.HF an... |
