Document Type and Number:
WIPO Patent Application WO/2021/117221
Kind Code:
A1
Abstract:
The objective of the present invention is to provide technology for employing data measured by means of sensors installed in a vehicle to estimate infrastructure factors other than vehicle factors, in order to analyze and diagnose abnormal factors. To this end, the railway vehicle state monitoring and analyzing device is provided with: a vehicle factor estimating unit for estimating vehicle factor evaluation data, from vehicle data and evaluation data; an infrastructure factor extracting unit for extracting infrastructure factor evaluation data from the vehicle data, the evaluation data, and the vehicle factor evaluation data; an infrastructure factor estimating unit for estimating individual infrastructure factor evaluation data from the infrastructure factor evaluation data; an infrastructure factor database constructing unit for storing the individual infrastructure factor evaluation data in an infrastructure factor database; an infrastructure factor analyzing unit for analyzing the infrastructure factors by monitoring the individual infrastructure factor evaluation data stored in the infrastructure factor database; and a vehicle analyzing unit for analyzing the vehicle state with reference to the infrastructure factor analysis information.
