Fault detection method, device and equipment based on rail transit train and medium

The embodiment of the invention provides a fault detection method, device and equipment based on a rail transit train and a medium. The method comprises the steps that vehicle vibration data and rail surface data collected in the running process of the rail transit train are obtained; preprocessing the vehicle vibration data and the track surface data to obtain a data set; performing rail surface fault detection by adopting a first part of data in the data set, and performing bearing fault detection and/or vehicle imbalance fault detection by adopting a second part of data in the data set; wherein the first part of data is different from the second part of data. According to the embodiment of the invention, joint detection of the rail surface fault, the bearing fault and the vehicle imbalance fault is realized, and the fault detection efficiency is improved. 本发明实施例提供了基于轨道交通列车的故障检测方法、装置、设备及介质，所述方法包括：获取在轨道交通列车运行过程中采集的车辆振动数据和轨道表面数据；对所述车辆振动数据和轨道表面数据进行预处理，得到数据集；采用所述数据集中第一部分数据，进行轨道表面故障检测，并采用所述数据集中第二部分数据，进行轴承故障检测和/或
