The invention relates to the technical field of rail transit, in particular to a danger alarm method and device for rail transit and a rail vehicle, and the method comprises the steps: obtaining the heartbeat sound of a driver in the vehicle driving process in real time; the heartbeat sound is input into a preset self-adaptive filter to be processed, a heartbeat signal output by the self-adaptive filter is obtained, and the coefficient of the self-adaptive filter is adjusted by minimizing the mean square error between an input signal and an expected signal; feature extraction is carried out on the heartbeat signal, the driving state of the driver is evaluated based on a feature extraction result, and the driving state comprises dangerous driving and normal driving; and under the condition that the evaluation result of the driving state is dangerous driving, alarm information is sent out, and the alarm information comprises the identification and position information of the vehicle. According to the invention, dangerous events can be detected in real time, and an alarm is automatically sent, so that the safety of rail transit is improved.

    本发明涉及轨道交通技术领域,尤其涉及一种用于轨道交通的危险报警方法、装置和轨道车辆,方法包括:实时获取车辆行驶过程中驾驶员的心跳声音;将所述心跳声音输入预设的自适应滤波器中进行处理,得到所述自适应滤波器输出的心跳信号,其中,所述自适应滤波器的系数通过最小化输入信号和期望信号之间的均方误差进行调整;对所述心跳信号进行特征提取,基于特征提取结果,对驾驶员的驾驶状态进行评估,所述驾驶状态包括危险驾驶和正常驾驶;在所述驾驶状态的评估结果为危险驾驶的情况下,发出报警信息,所述报警信息包括车辆的标识及位置信息。本发明能够实时检测危险事件,并自动发送警报,从而提高轨道交通的安全性。
