Abstract

For diagnosing a railroad switch with a point machine, a first and a second time series of a sensor signal of the point machine are received. Moreover, changes in the first and the second time series are detected indicating changes of operational conditions of the point machine. Furthermore, an event point of a respective change in the first and in the second time series is allocated to a respective component of the railroad switch or of the point machine based on a simulation modelling the respective component. Then for a respective component: event points allocated to that respective component are identified, the sensor signal at a first identified event point in the first time series is compared with the sensor signal at a second identified event point in the second time series, and depending on the comparison a component-specific fault information and an identification of the respective component are output.
