Abstract

A system for tracking train assets is disclosed. The tracking system may include an image capture device configured to collect an image data set of a train asset and an area surrounding the train asset. Furthermore, the image data set may be associated with a time stamp and in one non-limiting example, the time stamp provides a collection time of the image data set. In some embodiments, a controller may be configured to receive the image data set and to perform an analysis of the image data set and the analysis provides a track location of the train asset and an identification of the train asset.

First claim

What is claimed is:

1. A system for tracking train assets, the system comprising:
a first image capture device disposed along a railway, the first image capture device being configured to collect a first image data set of a first train asset and a first surrounding area of the first train asset;
a second image capture device disposed along the railway, the second image capture device being configured to collect a second image data set of a second train asset and a second surrounding area of the second train asset;
a first time stamp associated with the first image data set;
a second time stamp associated with the second image data set, the first time stamp providing a first collection time of the first image data set and the second time stamp providing a second collection time of the second image data set; and
a controller configured to receive and combine the first data set, the second data set, the first time stamp and the second time stamp into a consolidated data set, the controller performing an analysis on the consolidated data set and providing a track location for the first train asset and the second train asset and an identification of the first train asset and the second train asset.

2. The system of claim 1 , wherein the first image capture device is deployed at a fixed location along the railway, the first image capture device configured to collect the first image data set as the first train asset passes by the first image capture device.

3. The system of claim 1 , wherein the second image capture device is mounted on a mobile train asset moving along the railway and the second image capture device is configured to collect the second image data set as the second train asset passes by the second image capture device.

4. The system of claim 1 , wherein the first image capture device and the second image capture device are configured to collect a continuous video stream of the first image data set and the second image data set.

5. The system of claim 1 , wherein the analysis of the consolidated image data set uses an image recognition and time stamp algorithm to provide a track location for the first train asset and the second train asset and an identification of the first train asset and the second train asset.

6. The system of claim 1 , wherein the first image capture device is operatively coupled to a first control module, the second image capture device is operatively coupled to a second control module, the first control module and the second control module are used to start and stop a collection of the first image data set and the second image data set and to adjust a field of view of the first image capture device and the second image capture device.

7. The system of claim 6 , wherein the first control module is coupled to a first storage device and the first image data set is saved to the first storage device, the second control module is coupled to a second storage device and the second image data set is saved to the second storage device, the first control module and the second control module communicate wirelessly with the controller, sending the first image data set and the second image data set to the controller located in a remote office.

8. The system of claim 6 , wherein the first image capture device is communicably coupled to a first active position sensor, the second image capture device is communicably coupled to a second active position sensor and the controller uses the first active position sensor, the second active position sensor, the first image data set and the second image data set during the analysis performed by the controller.

9. The system of claim 8 , wherein the first image capture device is communicably coupled to a first automatic equipment identification system, the second image capture device is communicably coupled to a second automatic equipment identification system and during the analysis the controller combines a first data set produced by the first automatic equipment identification system with the first image data set and a second data set produced by the second automatic equipment identification system with the second image data set.

10. A method of tracking train assets, the method comprising:
installing a first image capture device at a fixed location along a railway, the first image capture device configured to collect a first image data set of a first train asset and a first area surrounding the first train asset;
mounting a second image capture device on a mobile train asset moving along the railway, the second image capture device configured to collect a second image data set of a second train asset and a second area surrounding the second train asset;
providing a first time stamp associated with the first image data set and a second time stamp associated with the second image data set, the first time stamp providing a collection time of the first image data set and the second time stamp providing a collection time of the second image data set;
using a controller to receive and combine the first image data set, the first time stamp, the second image data set and the second time stamp into a consolidated data set;
performing an analysis with the controller on the consolidated data set to provide a track location for the first train asset and the second train asset and an identification of the first train asset and the second train asset.

11. The method of claim 10 , wherein the first image data set is a first continuous video stream and the second image data set is a second continuous video stream, the consolidated image data set uses an image recognition and time stamp algorithm to provide a track location of the first train asset and the second train asset and an identification of the first train asset and the second train asset;
the first image capture device is operatively coupled to a first control module, the second image capture device is operatively coupled to a second control module, the first control module and the second control module are communicably coupled to the controller, the first control module and the second control module wirelessly send the first image data set and the second image data set to the controller located in a remote office; and
the first image capture device is communicably coupled to a first active position sensor and a first automatic equipment identification system, the second image capture device is communicably coupled to a second active position sensor and a second automatic equipment identification system, the analysis performed by the controller correlates the consolidated data set with an output from the first active position sensor, an output from the second active position sensor, an output from the first automatic equipment identification system and an output with the second active position sensor and the analysis provides the track location and the identification of the first train asset and the second train asset.
