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.

First claim

The invention claimed is:

1. 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 a transmitter on the rail vehicle to a receiver of the control center arranged trackside;
capturing further measured values by measuring devices that are independent of the rail vehicle;
evaluating the measured values from the rail vehicle in a controller of the control center by way of a prescribed algorithm to form an evaluation result; and
providing the evaluation result from the controller for output;
wherein the evaluation of the measured values from the rail vehicle in the controller of the control center by way of the prescribed algorithm is effected based directly on the further measured values that are captured independently of the rail vehicle by the measuring devices that are independent of the rail vehicle; and
wherein the prescribed algorithm includes a trend analysis of the measured values for predicting whether the measured values will exceed a threshold value.

2. The method according to claim 1 , which comprises transmitting the evaluation result to the rail vehicle and outputting the evaluation result on the rail vehicle.

3. The method according to claim 1 , which comprises outputting the evaluation result on the line.

4. The method according to claim 1 , which comprises transmitting the measured values from the rail vehicle to the control center cyclically.

5. The method according to claim 1 , which comprises transmitting the measured values from the rail vehicle to the trackside control center wirelessly.

6. The method according to claim 1 , 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.

7. A system, comprising:
at least one rail vehicle and at least one control center having at least one receiver;
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 receiver of said control center; and
said control center having at least one controller for evaluating the measured values by way of a prescribed algorithm;
wherein said controller is configured for evaluating the measured values from the rail vehicle based directly on further measured values that are captured independently of the rail vehicle;
wherein said controller is configured for evaluating the measured values from the rail vehicle by way of the prescribed algorithm based directly on the further measured values that are captured independently of the rail vehicle; and
wherein the prescribed algorithm includes a trend analysis of the measured values for predicting whether the measured values will exceed a threshold value.

8. The system according to claim 7 , wherein said controller is configured for evaluating the measured values by way of a plurality of different prescribed algorithms.

9. The system according to claim 7 , 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.

10. The system according to claim 7 , wherein said controller is configured to output an audible alarm to a driver of the rail vehicle as a result of said controller evaluating the measured values by way of the prescribed algorithm.

11. The method according to claim 1 , wherein the step of providing the evaluation result from the controller for output includes outputting the evaluation result as an audible alarm to a driver of the rail vehicle.

12. The system according to claim 7 , wherein said controller is configured to output an evaluation result advising that a door be shut down as a result of said controller evaluating the measured values by way of the prescribed algorithm.

13. The method according to claim 1 , wherein the evaluation result advises that a door be shut down as a result of said controller evaluating the measured values by way of the prescribed algorithm.
