Abstract

A system and method for automating railroad maintenance by a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables collision avoidance between members of the tie gang performing maintenance on railway assets (e.g., Rails, Ties, Ballasts, Turnouts, Crossings, etc.). The system can generate production numbers for the railway assets and evaluate an asset queue for the tie gang to perform maintenance. The system can utilize real-time updates from the tie gang to optimize work output. The system can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset. The system also provides for a heads-up-display (HUD) to notify an operator of relevant information, such as maintenance information, travel indicators, and updated asset queue. The system can identify a next location and calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics.

First claim

What is claimed is:

1. A heads-up display (HUD) system for indicating railway transportation directions and railway assets on which to perform maintenance, comprising:
a real-time sensor array for identifying a location of a machine from a plurality of acquired sensor inputs;
a display configured to display railway transportation directions and identify railway assets on which to perform maintenance;
a memory for storing the acquired sensor inputs and location data relating to the acquired sensor inputs, and information of a surrounding environment of the machine; and
a processor that is configured to identify the surrounding environment and update the display according to the location of the machine by performing the steps of:
displaying railway information onto the display;
displaying transportation information from a maintenance file based on the location of the machine on the display, wherein the transportation information includes a plurality of notices related to a path ahead of the machine;
receiving maintenance information from the maintenance file to display workhead information on the display, wherein the maintenance information includes a first symbol to indicate a location of one or more of the railway assets, a second symbol to indicate that the railway assets are to receive maintenance based on a queue of railway assets, and a third symbol to indicate that the railway assets are not to receive maintenance based on the queue of railway assets; and
displaying an updated icon based on a completion of maintenance according to the maintenance information and an updated location of the machine.

2. The system of claim 1 , wherein the acquired sensor inputs include data from a high-resolution radar.

3. The system of claim 1 , wherein the processor is further configured to perform the steps of identifying whether to update the maintenance file in response to completed maintenance on railway assets.

4. The system of claim 3 , wherein the processor is further configured to perform the steps of updating the maintenance file based on the completed maintenance on the railway assets.

5. The system of claim 1 , wherein the display is a device for displaying information in augmented reality (AR).

6. The system of claim 1 , wherein the updated icon is based on a type of maintenance to be performed corresponding to the railway asset.

7. The system of claim 1 , wherein the updated icon is at least one of various colored text or shapes.

8. The system of claim 1 , wherein the maintenance file includes the railway assets on which to perform maintenance and a corresponding location of the railway asset.

9. The system of claim 1 , wherein the workhead information includes spike puller information, tie kicker information, anchor spreader information, or relevant information relating to another workhead type.

10. A method of indicating railway transportation directions and railway assets on which to perform maintenance, comprising:
collect real-time sensor inputs of an environment proximate a machine;
compare, via a processor, the real-time sensor inputs with location information to identify a location of the machine;
display transportation information on a display inside the cabin of the machine based on the location of the machine, wherein the transportation information includes a plurality of notices related to a path ahead of the machine;
receive maintenance information to display workhead information, corresponding to the maintenance information, inside the cabin of the machine, wherein the maintenance information includes a first symbol to indicate a location of one or more of the railway assets, a second symbol to indicate that the railway assets are to receive maintenance based on a queue of railway assets, and a third symbol to indicate that the railway assets are not to receive maintenance based on the queue of railway assets;
update, via the processor, a maintenance quality status for a maintenance item based on maintenance completion;
display an updated icon based on the completion of the maintenance and an updated location of the rail vehicle.

11. The method of claim 10 , wherein the display is configured to show icons that correspond to the various operations and maintenance the machine is configured to perform.

12. The method of claim 10 , further comprising updating a maintenance file in response to completed maintenance on railway assets.

13. The method of claim 12 , further comprising automatically determining the maintenance is complete.

14. The method of claim 10 , wherein the display is a device for displaying information in augmented reality (AR).

15. The method of claim 14 , wherein the display is at least a portion of a windshield.

16. The method of claim 14 , wherein the display includes AR lenses.

17. The method of claim 10 , wherein the maintenance file includes the railway assets on which to perform maintenance and a corresponding location of the railway asset.

18. The method of claim 10 , wherein the workhead information includes spike puller information, tie kicker information, anchor spreader information, or relevant information relating to another workhead type.
