Detektering av avsporing ved bestemmelse av fallhastighet

A method and a device for the recognition of a derailment state of a wheel (RAD) of a rail vehicle. The acceleration of the wheel (RAD) is measured perpendicularly to a rail plane ( ) with at least one acceleration sensor (SEN), whereby from an acceleration signal (BSI) generated by the acceleration...

Zusammenfassung:	A method and a device for the recognition of a derailment state of a wheel (RAD) of a rail vehicle. The acceleration of the wheel (RAD) is measured perpendicularly to a rail plane ( ) with at least one acceleration sensor (SEN), whereby 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 ( ), and whereby on the basis of the determined fall speed (FAG), one examines whether a derailed state exists.
