Abstract:
1. A method for diagnosis and state monitoring of a wear and functional state of a junction, a crossing, a crossroads, or rail joints of a rail traffic path made of several tracks, wherein the method comprises the steps of: measuring and storing swing acceleration of at least one rail vehicle component of a rail vehicle in at least one direction by means mounted onboard of the rail vehicle, the swing acceleration being produced on the at least one rail vehicle component with the rail vehicle passing at the junction, crossing, crossroads or rail joints, measuring and storing the rail vehicle speed and determining and storing the travel direction, as well as place of the junction, crossing, crossroads or rail joints through a satellite supported position indication device, processing and evaluating by means mounted onboard of the rail vehicle the measured swing acceleration, rail vehicle speed, travel direction and positions in order to forecast maintenance deadlines and the corresponding maintenance efforts, carrying out a control as to whether characteristic, predetermined threshold values of the measured swing accelerations have been exceeded and a subsequent further measurement of the state of the junction, crossing, crossroads or rail joints, if the predetermined threshold values of the swing acceleration have been exceeded.
