The invention discloses a safety monitoring method and device for a running gear of a motor train unit. The method comprises the following steps: detecting and collecting the state parameters of all parts of the running gear of the motor train unit, wherein the state parameters at least comprise one of vibration, pressure, temperature and noise; conditioning the collected state parameters so as toconvert the state parameters into a digital signal which can be used for corresponding calculation models; substituting the digital signal into a corresponding calculation model and carrying out preprocessing calculation to generate a calculation result; carrying out fault comprehensive analysis according to the digital signal and the calculation result to obtain a fault diagnosis result of the train; and outputting the calculation result and the fault diagnosis result. Through comprehensive safety monitoring of the running gear of the motor train unit, fault hidden dangers and abnormal trends influencing the running safety can be found in advance, and pre-alarm is carried out in time, so that the running safety of the high-speed rail train is powerfully guaranteed, and the running risk is reduced.

    本发明公开了一种动车组走行部安全监测方法和装置,该方法包括:检测并收集动车组走行部各零部件的状态参数,状态参数至少包括振动、压力、温度、噪声中的一种;对收集到的状态参数进行调理,以将状态参数转换为能够用于相应计算模型的数字信号;将数字信号代入相应计算模型进行预处理计算,产生计算结果;根据数字信号以及计算结果进行故障综合分析,得出列车的故障诊断结果;输出计算结果和故障诊断结果。本发明通过对动车组走行部的综合安全监测,能够提前发现影响行车安全的故障隐患和异常趋势,并及时进行预报警,有力保障了高铁列车运行安全、降低运行风险。
