Document Type and Number:
WIPO Patent Application WO/2022/264518
Kind Code:
A1
Abstract:
The present invention: corrects a plurality of performance run curves obtained by operation of a train so that a mutual correspondence relationship therebetween can be obtained; and enables vehicle equipment operation conditions at corresponding time points to be collected so as to realize improved maintenance precision and maintenance efficiency based on a statistical analysis of such conditions. Provided is a railway maintenance data analysis assistance method, in which an information processing device comprising a processor and a memory: stores multiple pieces of run curve data which are groups of data indicating a relationship between a time and a speed during train operation; compares the extracted pieces of run curve data to each other; and corrects one of the pieces of run curve data so that the pieces of run curve data are approximated and fall within a predetermined acceptable error range.
