Determination of operating states relating to wheel-rail parings of a train and track, e.g. for determining wear of the rail or wheel surface, whereby two optical projection-imaging systems are used to improve diagnosis

摘要

Method for determining at one or more values relating to a wheel-rail pairing, whereby for determination of each value an arrangement of projection device and receiver arranged at angles to the longitudinal rail axis are mounted on the train or carriage. An Independent claim is made for a device for determining wheel-rail pairing values, with two projection-receiver arrangements and an evaluation device for evaluation of the projected light.
