Abstract

The invention relates to a method and device for recognizing a derailment state of wheel (RAD) of a railway vehicle, in which the acceleration of the wheel (RAD) perpendicular to a rail plane (.epsilon.) is measured by at least one acceleration sensor (SEN). A rate of fall (FAG) of the wheel (RAD) in the direction of the rail plane (.epsilon.) is determined based on an acceleration signal (BSI), which is produced by the acceleration sensor (SEN), by simple integration (INT) of a value that can be predetermined over a time window, and the existence of a derailed state is verified based on the determined rate of fall (FAG).

Claims (20)

1. Method for recognition of a derailment state of a wheel (RAD) of a rail vehicle, where the acceleration of the wheel (RAD) is measured perpendicularly to a rail plane (.epsilon.) with at least one acceleration sensor (SEN), characterized in that from an acceleration signal (BSI) generated by the acceleration sensor (SEN) by means of simple integration (INT) over a time window of predeterminable magnitude, one determines a fall speed (FAG) of the wheel (RAD) in the direction of the rail plane (.epsilon.), and where, on the basis of the determined fall speed (FAG), one examines whether a derailed state exists.
2. Method according to Claim 1, characterized in that the determined fall speed is compared to a boundary fall speed (GFG), where one concludes that there is a derailed state as the boundary fall speed (GFG) is exceeded.
3. Method according to Claim 1, characterized in that one concludes that there is a derailed state from the time curve of the fall speed (FAG).
4. Method according to one of Claims 1 to 3, characterized in that the acceleration signal (BSI) is generated in an area of an axle bearing (ALA) of a wheel (RAD) of the rail vehicle.
5. Method according to one of Claims 1 to 4, characterized in that low-frequency jamming portions, contained in the acceleration signal (BSI), are eliminated prior to integration (INT) by means of filtration (FIL).
6. Method according to one of Claims 1 to 5, characterized in that one uses high-pass filtration to eliminate the jamming portions.
7. Method according to one of Claims 1 to 6, characterized in that phase relationships of frequency portions of the acceleration signal to be integrated (BSI) are preserved among each other during filtration (FIL).
8. Method according to one of Claims 1 to 7, characterized in that the integration (INT) of the acceleration signal (BSI) is performed in each case in successive time windows, where the terminal point of a time window forms the starting point of a subsequent time window.
9. Method according to one of Claims 1 to 8, characterized in that the integration of the acceleration signal (BSI) is performed in each case in successive time windows, where successive time windows overlap each other segment by segment.
10. Method according to one of Claims 1 to 9, characterized in that an acceleration signal (BSI) is generated in the area of each wheel (RAD) of the rail vehicle.
11. Device for the recognition of a derailment state of a wheel (RAD) of a rail vehicle, which has at least one acceleration sensor (BSE) for the acquisition of the acceleration of the wheel (RAD) perpendicularly to a rail level (.epsilon.), whereby the acceleration sensor (BSE) is set up with an analysis unit (ASW) for the analysis of an acceleration signal (BSI) that is generated by the acceleration sensor (BSE), characterized in that the analysis unit (ASW) is so outfitted as to determine from the acceleration signal (BSI) by means of simple integration (INT) over a time window of predeterminable magnitude a fall speed (FAG) of the wheel (RAD) in the direction of rail level (.epsilon.) and where, on the basis of the determined fall speed (FAG), one can examine whether a derailed state exists.
12. Device according to Claim 11, characterized in that the analysis unit (ASW) is so set up as to compare the determined fall speed (FAG) with a boundary fall speed (GFG), where one can conclude that there is a derailed state when the boundary fall speed (GFG) is exceeded.
13. Device according to Claim 11, characterized in that the analysis unit (ASW) is so set up as to recognize a derailed state on the basis of the time curve of the fall speed (FAG).
14. Device according to one of Claims 11 to 13, characterized in that the acceleration sensor (BSE) is arranged in the area of an axle bearing (ALA) of a wheel (RAD) on the rail vehicle.
15. Device according to one of Claims 11 to 14, characterized in that a filter (FIL) is provided to eliminate low-frequency jamming portions contained in the acceleration signal (BSI) prior to integration (INT).
16. Device according to Claim 15, characterized in that the filter (FIL) is a high-pass filter.
17. Device according to Claim 15 or 16, characterized in that the filter (FIL) essentially exerts no influence on the phase relationships between frequency portions of the acceleration signal (BSI).
18. Device according to one of Claims 11 to 17, characterized in that the analysis unit (ASW) is set up to perform the integration (INT) of the acceleration signal (BSI) each time in successive time windows, where the terminal point of one time window will form the starting point of the subsequent time window.
19. Device according to one of Claims 11 to 17, characterized in that the analysis unit (ASW) is set up to perform the integration of the acceleration signal (BSI) each time in successive time windows, whereby successive time windows will overlap each other segment by segment.
20. Device according to one of Claims 1 to 19, characterized in that an acceleration sensor (BSE) is arranged in the area of each wheel (RAD) of the rail vehicle.
