DIAGNOSTIC SYSTEM AND METHOD FOR MONITORING A RAIL SYSTEM

摘要

The vehicles (12) of at least one fleet of rail vehicles are provided with on-board sensors (22) and rail vehicle positioning means (23). The rail infrastructure on which the rail vehicles circulate is provided with fixed rail infrastructure sensors (18). The rail infrastructure-related sensor data is merged with the rail vehicle-related sensor data, with location data representative of the location of the rail infrastructure-related sensors and with the rail vehicle position data for generating series of categorized event data representative of the occurrence of categorized events at a given location on the rail infrastructure over time and/or on a given rail vehicle of the fleet over time. The series of categorized events data representative of at least one category of events can be compared over any predetermined period of time to identify any location of the rail infrastructure and/or any rail vehicle which exhibits a series of events data that is significantly different from the other locations of the rail infrastructure and/or rail vehicles of the fleet over said predetermined period of time.
