Railway steel rail corrugation recognition method and device

The invention discloses a railway steel rail corrugation recognition method and device, and relates to the technical field of railway engineering engineering.The method comprises the steps that axle box acceleration data are preprocessed, and a plurality of time domain data fragments, running vehicle speed data of each time domain data fragment and a time-frequency graph corresponding to each time domain data fragment are obtained; determining a railway line type and steel rail corrugation information corresponding to each time domain data segment; constructing a sample data set by using the plurality of time domain data fragments, the running speed data of each time domain data fragment, the time-frequency graph corresponding to each time domain data fragment, and the railway line type and steel rail corrugation information corresponding to each time domain data fragment; training a pre-constructed neural network model by using the sample data set to obtain a steel rail corrugation recognition model; and det
