Abstract

A visual diagnostic system for a rail vehicle having multiple assets is disclosed. The visual diagnostic system may have a data interface configured to receive a data stream from a wayside unit. The data stream includes values of a plurality of parameters measured made by the wayside unit. The data interface may also be configured to receive geo-information and configuration-information. The system further includes a memory device configured to store the data stream and a controller configured to determine, from the geo-information and the configuration-information, a geographic location of each of the multiple assets. The controller is further configured to determine prognostic information associated with an operational status of each of the multiple assets. The controller may further render for display in a user interface a visual representation of the rail vehicle with the prognostic information for each asset of the rail vehicle.

Claims

1. A visual diagnostic system for a rail vehicle having multiple assets, comprising:

a data interface configured to;

receive a data stream from a wayside unit, wherein the data stream includes values of a plurality of parameters measured by the wayside unit;

receive geo-information associated with a geographic location of the rail vehicle; and

receive configuration-information including an order in which the multiple assets are arranged in the rail vehicle;

a memory device configured to store the data stream; and

a controller in communication with the data interface and the memory device, the controller being configured to;

determine, from the geo-information and the configuration-information, a geographic location of each of the multiple assets;

identify, from the received data stream and the determined geographic location of each of the multiple assets, an asset that is experiencing an operational status that is one of outside a normal limit or trending toward falling outside a normal limit, the asset being selected from the multiple assets; and

render for display in a user interface a visual representation of the rail vehicle, the visual representation including a graphical icon associated with the identified asset.

2. The visual diagnostic system of claim 1, wherein the plurality of parameters includes at least one of:

a bearing temperature, a wheel temperature, and a brake temperature.

3. The visual diagnostic system of claim 1, wherein the wayside unit is a first wayside unit and the data interface is further configured to receive an additional data stream from a second wayside unit, physically separated from the first wayside unit.

4. The visual diagnostic system of claim 1, wherein the data interface is configured to receive the geo-information from multiple sources, and the controller is further configured to combine the geo-information from the multiple sources when determining the geographic location of each of the multiple assets.

5. The visual diagnostic system of claim 1, wherein the data interface is configured to receive the geo-information from at least one of:

a Global Positioning System (GPS) located on the rail vehicle, an Automatic Equipment Identification (AEI) system, an Automatic Train Protection (ATP) system, and a video monitoring system.

6. The visual diagnostic system of claim 1, wherein the data interface is configured to receive the configuration-information from multiple sources, and the controller is further configured to combine the configuration-information from the multiple sources when determining the geographic location of each of the multiple assets.

7. The visual diagnostic system of claim 1, wherein the data interface is configured to receive the configuration-information from at least one of:

an electronically controlled pneumatic (EPC) braking system, a train scheduling system, an Automatic Equipment Identification (AEI) system, and a video monitoring system.

8. The visual diagnostic system of claim 1, wherein the controller is located on-board the rail vehicle, and the user interface is displayed on an on-board screen.

9. The visual diagnostic system of claim 1, wherein the controller is located at a remote location, and the user interface is displayed on a mobile terminal device.

10. The visual diagnostic system of claim 1, wherein:

the data stream includes timestamps associated with the measured parameters;

the geo-information includes timestamps of signals with data about the geographic location of the rail vehicle; and

the controller is further configured to determine the operational status of each of the multiple assets using the timestamps associated with measured parameters and the timestamps of the signals.

11. The visual diagnostic system of claim 1, wherein the controller is further configured to render for display in the user interface information about a current operational status of all bearings of at least one of the multiple assets.

12. The visual diagnostic system of claim 1, wherein the controller is further configured to render for display in the user interface information about a current operational status of all wheels of at least one of the multiple assets.

13. The visual diagnostic system of claim 1, wherein the controller is further configured to:

receive a selection of a specific component; and

render for display in the user interface historical values for specific parameters associated with the selected component.

14. The visual diagnostic system of claim 1, wherein the data stream is a first data stream and:

the data interface is further configured to receive at least a second data stream from the wayside unit;

the memory device is further configured to store the at least the second data stream; and

the controller is further configured to;

aggregate prognostic information determined from the first and at least the second data streams; and

render for display in the user interface the aggregated prognostic information associated with the operational status for each of the multiple assets.

15. The visual diagnostic system of claim 14, wherein the aggregated information represents changes in the operational status over a period of time.

16. A method for providing visual information on a rail vehicle having multiple assets, comprising:

receiving a data stream from a wayside unit, wherein the data stream includes values of a plurality of parameters measured by the wayside unit;

receiving geo-information associated with a geographic location of the rail vehicle;

receiving configuration-information including an order in which the multiple assets are arranged in the rail vehicle;

determining, from the geo-information and the configuration-information, a geographic location of each of the multiple assets;

identifying, from the received data stream and the determined geographic location of each of the multiple assets, an asset that is experiencing an operational status that is one of outside a normal limit or trending toward falling outside a normal limit, the asset being selected from the multiple assets; and

rendering for display in a user interface a visual representation of the rail vehicle, the visual representation including a graphical icon associated with the identified asset.

17. The method of claim 16, wherein the plurality of parameters includes at least one of:

a bearing temperature, a wheel temperature, and a brake temperature.

18. The method of claim 16, wherein the wayside unit is a first wayside unit and the data interface is further configured to receive an additional data stream from a second wayside unit, physically separated from the first wayside unit.

19. The method of claim 16, further comprising:

receiving a selection of a specific component; and

rendering for display in the user interface historical values for specific parameters associated with the selected component.

20. A computer programmable medium having executable instructions stored thereon for completing a method for providing visual information on a rail vehicle having multiple assets, the method comprising:
