Abstract

A method and a system for diagnosing one or more rail vehicles, each of which has at least one measuring device for measuring measurement values of at least one measurement variable. The method includes the following steps: measuring measurement values by way of at least one measuring device of at least one rail vehicle; transmitting the measurement values from the rail vehicle to a control center situated along the track; evaluating the measurement values in the control center by means of a predefined algorithm, and providing a result of the evaluation as an output.

Claims

1-11. -11. (canceled)

12. A diagnosis method for a rail vehicle, the rail vehicle having at least one measuring device for capturing measured values of at least one measured variable, the method comprising the following method steps:

capturing measured values by way of the at least one measuring device of the rail vehicle;

transmitting the measured values from the rail vehicle to a control center arranged trackside;

evaluating the measured values in the control center by way of a prescribed algorithm to form an evaluation result; and

providing the evaluation result for output.

13. The method according to claim 12, which comprises transmitting the evaluation result to the rail vehicle and outputting the evaluation result on the rail vehicle.

14. The method according to claim 12, which comprises outputting the evaluation result on the line.

15. The method according to claim 12, which comprises transmitting the measured values from the rail vehicle to the control center cyclically.

16. The method according to claim 12, which comprises capturing further measured values by measuring devices that are independent of the rail vehicle, and evaluating the further measured values by way of the prescribed algorithm.

17. The method according to claim 12, wherein the prescribed algorithm is suitable for trend analysis of the measured values.

18. The method according to claim 12, which comprises transmitting the measured values from the rail vehicle to the trackside control center wirelessly.

19. The method according to claim 12, wherein the measured variables for which first and/or second measured values are captured are selected from the group consisting of a speed of the rail vehicle, an acceleration of the rail vehicle, a speed of a drive motor, an electric motor current, an electric voltage of a motor, and a thermodynamic temperature of a drive.

20. A system, comprising:

at least one rail vehicle and at least one control center;

said rail vehicle having at least one measuring device for capturing measured values for at least one measured variable and at least one transmitter for transmitting the measured values from the rail vehicle to said control center; and

said control center having at least one receiver for receiving the measured values transmitted from said rail vehicle to said control center and at least one controller for evaluating the measured values by way of a prescribed algorithm.

21. The system according to claim 20, wherein said controller is configured for evaluating the measured values by way of a plurality of different prescribed algorithms and/or for evaluating the measured values from the rail vehicle and further measured values that are captured independently of the rail vehicle.

22. The system according to claim 20, which comprises a plurality of rail vehicles having measuring devices for capturing measured values for identical measured variables, and wherein said controller is configured for evaluating the measured values by way of the prescribed algorithm in said control center.
