The invention relates to the technical field of data processing, in particular to a method for monitoring rail vibration data abnormity in train operation. The method comprises the steps of obtaining an initial orbit vibration data sequence; sampling the initial orbit vibration data sequence by using different sampling step lengths to obtain a minimum period corresponding to the initial orbit vibration data sequence; obtaining each target sub-sequence according to the minimum period; according to the track vibration data at the same position in each target sub-sequence, obtaining each recombined track vibration data sequence; noise track vibration data are obtained according to the track vibration data in the recombined track vibration data sequences; obtaining a target track vibration data sequence according to the noise track vibration data and the data mean value corresponding to each recombined track vibration data sequence; and obtaining abnormal track vibration data in the target track vibration data sequence according to the target track vibration data sequence. According to the invention, the accuracy of monitoring the abnormal track vibration data can be improved.
