Abstract

A rail vehicle includes of one or more locomotives and may further include one or more rail cars, and the rail vehicle further includes a locator element, a communications device and a control module located on the rail vehicle. The locator elements provide a location information of the rail vehicle to a control module. The control module is coupled to the communications device and the locator element. The control module determines control settings for controlling the operations of the communications device based on the location of the rail vehicle. The communications device sends and/or receives data, including communications data, off-board the rail vehicle.

Claims

1. A method for communicating data for a rail vehicle, the method comprising:

determining a first location of the rail vehicle;

determining a first control setting of a communications device based on the determined first location of the rail vehicle, the communications device being located on the rail vehicle and configured for communications off board the rail vehicle;

automatically controlling the communications device based on the first control setting, wherein the first control setting comprises a designated first communication channel for use in communicating with rail vehicles in a particular geographic region;

automatically determining that the rail vehicle is traversing and/or has traversed from the first location where the first control setting is used for communicating with the rail vehicle, to a second location where a second control setting is used for communicating with the rail vehicle, wherein the second control setting comprises designated second communication channel for use in communicating with rail vehicles in a region comprising the second location; and

controlling the communications device by automatically switching the communications device from the first control setting to the second control setting.

3. The method of claim 1, wherein the first location and/or the second location are determined using information from one or more locator elements, the locator elements comprising at least one of a GPS unit located on the rail vehicle, a wayside device, a control system of the rail vehicle, and/or a cell phone network device.

4. The method of claim 3, wherein the first location and/or the second location are determined based at least in part on switching between at least one of the GPS unit located on the rail vehicle, the wayside device, the control system of the rail vehicle, and/or the cell phone network device.

5. The method of claim 3 wherein the first location and/or the second location are determined at least in part by comparing concurrent location information from multiple locator elements.

6. The method of claim 1 further comprising displaying and/or annunciating a message, wherein the message relates to at least one of a control setting of the communications device and/or an operational parameter of the rail vehicle comprising one or more of a speed of the rail vehicle, a designated speed for the rail vehicle for a particular section of a rail track, a time to reach destination, a time elapsed from a previous stoppage, a journey time, an estimated distance at which the control setting may be changed, an estimated time at which the control setting may be changed, a distance to destination, a distance covered during the journey, or a current signal for the train.

14. The method of claim 1, wherein automatically controlling the communications device based on the first control setting comprises:

automatically providing the first control setting to the communications device;

annunciating the first control setting to an operator; and

applying the first control setting to the communications device upon receiving an operator input.

2. A method for communicating data for a rail vehicle, the method comprising:

determining a first location of the rail vehicle;

determining a new control setting of a communications device based on the determined first location of the rail vehicle, the communications device being located on the rail vehicle and configured for communications off board the rail vehicle;

automatically providing the new control setting to the communications device, wherein the new control setting comprises a designated communication channel for use in communicating with rail vehicles in a first geographic region;

informing a human operator of the new control setting;

if the operator actuates a designated user interface, automatically switching the communications device from a current control setting of the communications device to the new control setting; and

determining that the rail vehicle has transitioned from a second, previous location to the first location, wherein the current control setting is a designated communication channel for use in communicating with rail vehicles in a second geographic region that encompasses the second, previous location.

7. A method for communicating data for a rail vehicle, the method comprising:

determining a first location of the rail vehicle;

determining a new control setting of a communications device based on the determined first location of the rail vehicle, the communications device being located on the rail vehicle and configured for communications off board the rail vehicle;

automatically providing the new control setting to the communications device, wherein the new control setting comprises a designated communication channel for use in communicating with rail vehicles in a first geographic region;

automatically switching the communications device from a current control setting of the communications device to the new control setting; and

determining that the rail vehicle has transitioned from a second, previous location to the first location, wherein the current control setting is a designated communication channel for use in communicating with rail vehicles in a second geographic region that encompasses the second, previous location.

15. The method of claim 7 further comprising:

informing a human operator of the new control setting; and

if the operator actuates a designated user interface, automatically switching the communications device from a current control setting of the communications device to the new control setting.

16. The method of claim 7 wherein:

the first location is determined by comparing a first concurrent location information from a first locator element to a second concurrent location information from a second, different locator element;

if the first concurrent location information and the second concurrent location information match within a designated threshold, the first location is determined based on the first concurrent location information and/or the second concurrent location information; and

if the first concurrent location information and the second concurrent location information do not match within the designated threshold, the first location is determined using a conflict resolution process.

8. A method for communicating data for a rail vehicle, the method comprising:

determining a first location of the rail vehicle, wherein the first location is determined by comparing a first concurrent location information from a first locator element and a second concurrent location information from a second locator element;

determining a first control setting of a communications device based on the determined first location of the rail vehicle, the communications device being located on the rail vehicle and configured for communications off board the rail vehicle; and

automatically controlling the communications device based on the first control setting, wherein the first control setting comprises a designated first communication channel for use in communicating with rail vehicles in a particular geographic region;

wherein determining the first control setting comprises;

determining the first control setting based on the first concurrent location information;

determining a second control setting based on the second concurrent location information; and

determining that a conflict has occurred if the first control setting is not the same as the second control setting.

9. The method of claim 8 further comprising re-determining the first concurrent location information and the second concurrent location information.

10. The method of claim 8 further comprising receiving the first control setting from a dispatch located off board the rail vehicle.

11. The method of claim 8 further comprising determining the first control setting using the first concurrent location information, wherein the first concurrent location information is likely to be more accurate than the second concurrent location information.

12. The method of claim 8 further comprising:

conducting a message test on the communications device configured according to the first control setting; and

preserving the first control setting as a current control setting of the communications device if a designated response is received on the communications device configured according to the first control setting.

13. The method of claim 8 further comprising receiving one or more new location information, respectively, from one or more new locator elements, for resolving the conflict.
