Abstract

An inspection system for use with a rail vehicle includes a database containing vehicle route data and at least one location of track to be inspected. The database may be accessed by rail vehicles with on-board inspection systems so that they may inspect the location of track to be inspected.

First claim

What is claimed is:

1. An inspection system, comprising:
a sensor system on board a rail vehicle configured for inspection of track on which the rail vehicle is configured to travel;
a database containing vehicle route data and at least one location of track to be inspected;
a global positioning system configured to determine a location of the rail vehicle along a route in the database;
a control system on board the rail vehicle, wherein the control system is configured to activate the sensor system for inspecting the track based on the location determined by the global positioning system as cross-referenced to the database;
wherein the database is configured to be accessed by the rail vehicle, when on a route contained in the database, for the rail vehicle to inspect one or more locations of track to be inspected along the route; and
wherein the database further contains one or more frequencies that the at least one location of track is to be inspected and one or more previous times that the at least one location of track was inspected, and wherein the control system is configured to activate the sensor system for inspecting the track further based on the one or more frequencies and the one or more previous times.

2. An inspection system, comprising:
a sensor system on board a rail vehicle configured for inspection of track on which the rail vehicle is configured to travel;
a database containing vehicle route data and at least one location of track to be inspected, wherein the database is configured to be accessed by the rail vehicle, for the rail vehicle, when on a route contained in the database, to inspect one or more locations of track to be inspected along the route;
a control system on board the rail vehicle, wherein the control system is configured to activate the sensor system for inspecting the track based on a location of the rail vehicle as cross-referenced to the database; and
wherein the database further contains one or more frequencies that the at least one location of track is to be inspected and one or more previous times that the at least one location of track was inspected, and wherein the control system is configured to activate the sensor system for inspecting the track further based on the one or more frequencies and the one or more previous times.

3. The system of claim 2 , wherein the database is configured to be updated with the at least one location of track to be inspected by an off-board scheduling system that is configured to schedule the movement of the rail vehicle and plural other rail vehicles in a transportation system that includes the track.

4. An inspection system, comprising:
a sensor system on board a rail vehicle configured for inspection of track on which the rail vehicle is configured to travel;
a database containing vehicle route data and at least one location of track to be inspected, wherein the database is configured to be accessed by the rail vehicle, for the rail vehicle, when on a route contained in the database, to inspect one or more locations of track to be inspected along the route;
a control system on board the rail vehicle, wherein the control system is configured to activate the sensor system for inspecting the track based on a location of the rail vehicle as cross-referenced to the database; and
an energy management system on board the rail vehicle, the energy management system configured to generate a trip plan to control movement of the rail vehicle, the trip plan comprising throttle settings as a function of at least one of location or time, and wherein the energy management system is configured to generate the trip plan based at least in part on the database.

5. The system of claim 4 , wherein the database is located on-board the rail vehicle.

6. The system of claim 4 , wherein the database is located off-board the rail vehicle.

7. The system of claim 4 , further comprising:
a global positioning system configured to determine a location of the rail vehicle along a route in the database.

8. The system of claim 4 , wherein the database is configured to be updated with the at least one location of track to be inspected from an off-board scheduling system that is configured to schedule the movement of the rail vehicle and plural other rail vehicles in a transportation system that includes the track.

9. The system of claim 4 , further comprising:
a global positioning system configured to determine a location of the rail vehicle along a route in the database;
wherein the control system is configured to activate the sensor system for inspecting the track based on the location determined by the global positioning system as cross-referenced to the database.

10. The system of claim 9 , wherein the database is configured to be updated with the at least one location of track to be inspected from an off-board scheduling system that is configured to schedule the movement of the rail vehicle and plural other rail vehicles in a transportation system that includes the track.

11. An inspection system comprising:
a sensor system on board a rail vehicle configured for inspection of track on which the rail vehicle is configured to travel;
a control system on board the rail vehicle, wherein the control system includes an energy management system on board the rail vehicle, the energy management system configured to generate a trip plan to control movement of the rail vehicle, the trip plan comprising throttle settings as a function of at least one of location or time; and
a database stored on a non-transient computer readable electronic storage medium, wherein the control system is configured to communicate with the database, and wherein the database contains vehicle route data, a location of track to be inspected, a frequency that the location of track is to be inspected, and a previous time that the location of track was inspected;
and wherein the control system is configured to activate the sensor system for inspecting the track based on the frequency, the previous time, and a location of the rail vehicle as cross-referenced to the database.

12. The system of claim 11 , wherein the computer readable electronic storage medium is on-board the rail vehicle.

13. The system of claim 11 , wherein the computer readable electronic storage medium is off-board the rail vehicle.

14. The system of claim 11 , wherein the database is configured to be updated with at least one of the location of track to be inspected, the vehicle route data, the frequency, or the previous time by an off-board scheduling system that is configured to schedule the movement of the rail vehicle and plural other rail vehicles in a transportation system that includes the track.

15. The system of claim 11 , wherein the energy management system is configured to automatically control movement of the rail vehicle based on the trip plan.

16. A method comprising the steps of:
establishing a time period during which a rail track inspection location is to be inspected;
identifying all rail inspection vehicles that will be traveling along a route containing the rail track inspect location during the established time period; and
directing rail inspection vehicles travelling along the route during the time period to inspect the inspection location.

17. The method of claim 16 , wherein the rail inspection vehicles are at least one of freight trains and passenger trains, and wherein the steps are carried out by an automated dispatch system that is configured to guide the movement of the at least one of the freight trains and passenger trains in a transportation netw
