基于生物反馈试验的高原公路驾驶员生理特性研究

Research on Driver's Physiological Characteristics on Plateau Highway Based on Biological Feedback Test

为了掌握高原公路海拔对驾驶员生理特性的影响规律,利用生物反馈系统对急进高原公路的驾驶员进行实地行车试验。通过定量分析,建立了驾驶员各项生理指标与试验路段海拔之间的关系模型。结果表明;高原公路行车驾驶员的各项生理指标都随海拔上升而表现出不同程度的变化;驾驶员心率增长率、LF/HF、LF以及脑电波"频段功率值与高原公路海拔成正相关,而表面肌电IEMG、血容振幅、HF指标与高原公路海拔表现出负相关性;其中,驾驶员心率增长率、LF/HF及脑电波"频段功率值三项指标与高原公路海拔的相关性较强,可以作为相关研究的备用指标。

In order to master the effect of altitude to driver＇s physiological characteristics on plateau highway,biofeedback instrument was used to test the driver who entry the plateau highway for the first time. On the basis of theoretical analysis,the relationship between the driver＇ s physiological characteristics and altitude on the experimental highway was respectively established. The analysis results show that,the driver＇s physiological characteristics change with the increase of altitude. The driver＇s heart rate of growth,LF/HF,LF and beta band power shows a positive correlation with the altitude. And the IEMG,PVA,HF shows a negative correlation with the altitude.Among all the physiological characteristics,the driver＇ s heart rate of growth,LF/HF and beta band power shows strong correlations with the altitude on the plateau highway,and these indexes may serve as reserve index on the correlational research.
