Beschreibung
Zusammenfassung:	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 se
