DIAGNOSTIC SYSTEM AND METHOD FOR MONITORING A RAIL SYSTEM

摘要

The vehicles (12) of at least one fleet of rail vehicles are provided wit h on-board sensors (22) and rail vehicle positioning means (23). The rail in frastructure on which the rail vehicles circulate is provided with fixed rai l infrastructure sensors (18). The rail infrastructure-related sensor data i s merged with the rail vehicle-related sensor data, with location data repre sentative of the location of the rail infrastructure-related sensors and wit h the rail vehicle position data for generating series of categorized event data representative of the occurrence of categorized events at a given locat ion on the rail infrastructure over time and/or on a given rail vehicle of t he fleet over time. The series of categorized events data representative of at least one category of events can be compared over any predetermined perio d of time to identify any location of the rail infrastructure and/or any rai l vehicle which exhibits a series of events data that is significantly diffe rent from the other locations of the rail infrastructure and/or rail vehicle s of the fleet over said predetermined period of time.
