The invention provides a driver state monitoring and early warning method, system and device, and the method comprises the steps: collecting fatigue state related data, environment data and vehicle operation state data of a driver before and during driving, and taking the fatigue state related data before driving as reference data; carrying out difference analysis on the fatigue state related data before driving and during driving, and then carrying out normalization to obtain a fatigue state comprehensive index of the driver; training a fatigue state recognition model through a machine learning algorithm on the basis of taking the reference data as non-fatigue state characteristic parameters and taking the fatigue state comprehensive indexes conforming to a preset fatigue state threshold range as fatigue state characteristic parameters; inputting the fatigue state related data acquired in real time during driving into a fatigue state recognition model to recognize the fatigue state of the driver; if the driver is in the fatigue state, the influence degree of the environment data and the vehicle running state data on the driving fatigue of the driver is determined through an entropy weight method, and corresponding early warning intervention is conducted.

    本发明提供一种驾驶员状态监测与预警方法、系统和装置,所述方法包括:采集驾驶员在驾驶前和驾驶中的疲劳状态相关数据、环境数据和车辆运行状态数据,并将驾驶前的疲劳状态相关数据作为基准数据;将驾驶前和驾驶中的疲劳状态相关数据进行差异分析后再进行归一化得到驾驶员的疲劳状态综合指标;基于以基准数据为非疲劳状态特征参数与以符合预设疲劳状态阈值范围的疲劳状态综合指标为疲劳状态特征参数通过机器学习算法训练疲劳状态识别模型;将实时采集的驾驶中的疲劳状态相关数据输入至疲劳状态识别模型识别驾驶员的疲劳状态;若驾驶员为疲劳状态,通过熵权法确定环境数据和车辆运行状态数据对驾驶员的驾驶疲劳的影响程度,进行相应地预警干预。
