The invention relates to a metro vehicle air brake fault detection method, device and equipment and a storage medium, and belongs to the technical field of fault diagnos.The metro vehicle air brake fault detection method comprises the steps that in-library data of metro vehicles are obtained according to metro vehicle in-library screening rules; the inflation and deflation cycle duration T of the subway train under the normal working condition is set; intercepting in-library data with the duration T and processing the in-library data to obtain a training data set; dividing the data in the training data set into normal data and fault data according to the operation and maintenance data of the metro vehicle, and establishing a metro vehicle air brake fault detection model; and obtaining to-be-detected data of metro vehicle operation, and importing the to-be-detected data into the metro vehicle air brake fault detection model to obtain a detection result. According to the metro vehicle air brake fault detection method, multi-dimensional detection of the metro vehicle is achieved through the multi-dimensional in-library data, and the accuracy of fault detection of the metro vehicle air brake system is effectively improved.

    本发明涉及一种地铁车辆空气制动故障检测方法、装置、设备及存储介质,属于故障诊断技术领域,该地铁车辆空气制动故障检测方法根据地铁车辆在库筛选规则获取地铁车辆的在库数据;设定地铁列车正常工况的充放气周期时长T;截取时长T的在库数据并进行处理,获得训练数据集;根据地铁车辆的运维数据,将训练数据集中的数据分为正常数据和故障数据,建立地铁车辆空气制动故障检测模型;获取地铁车辆运行的待检测数据,将待检测数据导入地铁车辆空气制动故障检测模型,获得检测结果。该地铁车辆空气制动故障检测方法通过多维度的在库数据,实现对地铁车辆的多维度检测,有效提升地铁车辆空气制动系统故障检测的准确性。
