摘要/Abstract

摘要： 适当的休息能有效缓解驾驶疲劳,提高行车安全。为探究科学的驾驶休息时间,开展试验,用MP150多通道生理信号采集仪,采集20名驾驶人4 h模拟驾驶作业后休息时的心电(ECG)信号,分析ECG信号的变化规律。结果表明:在驾驶疲劳恢复期,ECG指标心率(HR)、间期标准差(SDNN)、低高频比值(LF/HF)、样本熵(SampEn)与恢复时间高度线性相关,且性别差异对疲劳恢复期ECG指标有显著影响;驾驶人的心理疲劳恢复时间早于生理疲劳恢复时间;驾驶人主观恢复时间相对于客观疲劳恢复时间有提前现象;建议连续驾驶4 h后男性驾驶人休息时间不少于 24 min,女性驾驶人休息时间不少于27 min。

关键词: 驾驶疲劳, 恢复时间, 心电(ECG)信号, 疲劳类型, 心率(HR)

Abstract: Proper rest can alleviate driving fatigue and improve driving safety effectively. In order to explore the reasonable driving rest time, simulation experiments were carried out by using an MP150 multi-channels physiological signal acquisition instrument. 20 drivers' ECG signals in fatigue recovery process after 4 hours simulated driving were collected. Then the ECG data were analyzed for obtaining the objective and subjective driver fatigue recovery time. The results show that the HR, standard deviation in N-N intervals (SDNN),the ratio of low frequency to high frequency(LF/HF) and sample entropy (SampEn) have a high linear correlation with recovery time during the driving fatigue recovery process, that the gender has a significant influence on the ECG indicators, that driver's mental fatigue recovery time is shorter than that for physical fatigue, that the subjective recovery time is shorter than that for objective fatigue recovery the rest time for men should not be less than 24 min, that for women should not be less than 27 min after 4 hours' continuous driving.

Key words: driving fatigue, recovery time, electrocardiogram(ECG) signal, types of fatigue, heart rate(HR)
