Abstract

A railroad control system is disclosed for a network of trains. The system may include a centralized control system configured to transmit trip parameters for each train in the network. The system may include an energy manager in communication with the centralized control system and located onboard each train. The energy manager may be configured to determine an energy profile for a consist of the train based on the trip parameters. The system may further include a consist manager located onboard the consist and configured to determine a distribution of the energy profile for each locomotive of the consist. The system may also include one or more locomotive managers, each associated with a locomotive of the consist, and configured to determine a power configuration of the one locomotive based on the distribution of the energy profile and known parameters of the locomotive.

First claim

What is claimed is:

1. A railroad control system for a network of trains, comprising:
a centralized control system configured to transmit trip parameters for each train in the network;
an energy manager in communication with the centralized control system and located onboard each train, wherein the energy manager is configured to determine an energy profile for a consist of the train based on the trip parameters;
a consist manager located onboard the consist and configured to determine a distribution of the energy profile for each locomotive of the consist; and
one or more locomotive managers, each associated with a locomotive of the consist, and configured to determine a power configuration of the locomotive based on the distribution of the energy profile and known parameters of the locomotive, wherein the centralized control system includes an operator interface and a central controller, wherein the operator interface is configured to communicate with the energy manager via a first network, and the central controller is configured to communicate with the energy manager via a second network, and wherein the operator interface is configured to send unique commands to individual locomotives of the consist.

2. The railroad control system of claim 1 , wherein the trip parameters include one of an arrival time, a track assignment, and a speed.

3. The railroad control system of claim 1 , wherein the energy manager is configured to determine the energy profile prior to a trip departure.

4. The railroad control system of claim 1 , wherein the energy manager is configured to receive a signal indicating actual parameters of the train, make a comparison of the actual parameters and the energy profile, and selectively update the energy profile during the trip based on the comparison.

5. The railroad control system of claim 1 , wherein the distribution of the energy profile is asymmetric among the locomotives.

6. The railroad control system of claim 1 , wherein the power configuration includes load sharing between a plurality of engines or traction motors on the locomotive.

7. The railroad control system of claim 1 , wherein each locomotive manager only receives the distribution of the energy profile for the locomotive on which it is located.

8. The railroad control system of claim 1 , wherein the operator interface is configured to display parameters monitored onboard each locomotive.

9. The railroad control system of claim 1 , wherein the central controller is configured to transmit the trip parameters to the energy manager.

10. The railroad control system of claim 1 , wherein the operator interface is configured to send train-specific performance goals to the energy manager.

11. A method of controlling a railroad network including a plurality of trains, comprising:
transmitting trip parameters associated with a desired trip from a centralized control system to each train, wherein the centralized control system includes an operator interface and a central controller;
determining an energy profile using an energy manager for at least one consist of each train based on the trip parameters;
distributing the energy profile to each locomotive of the at least one consist;
determining a power configuration of engines and traction motors onboard each locomotive based on the distribution of the energy profile;
communicating with the energy manager using the operator interface via a first network;
communicating with the energy manager using the central controller via a second network; and
sending unique commands to individual locomotives of the consist using the operator interface.

12. The method of claim 11 , wherein the power configuration includes load sharing between a plurality of engines or traction motors on each locomotive.

13. The method of claim 11 , wherein the determining the energy profile is performed prior to the train departing on a trip.

14. The method of claim 13 , further comprising displaying parameters monitored onboard each locomotive.

15. The method of claim 13 , further comprising receiving a signal indicating actual parameters of the train, making a comparison of the actual train parameters to the energy profile, and selectively updating the energy profile during the trip based on the comparison.

16. The method of claim 13 , wherein the distributing the energy profile includes distributing the energy profile asymmetrically among each locomotive.

17. The method of claim 13 , further comprising receiving train-specific goals, and the determining the energy profile is based on the train-specific goals.

18. A railroad network comprising:
a network of trains, each train including at least one consist having one or more locomotives;
a centralized control system including:
an operator interface configured to receive train-specific goals;
a central controller configured to transmit trip parameters for each train;
an energy manager located onboard each consist and configured to determine and update an energy profile for the consist based on the trip parameters, train-specific goals, and current train parameters, wherein the operator interface is configured to communicate with the energy manager via a first network, and the central controller is configured to communicate with the energy manager via a second network;
a consist manager located onboard each consist and configured to determine a distribution of the energy profile for each locomotive of the consist, and distribute the energy profile among each locomotive of the consist; and
a plurality of locomotive managers, each locomotive manager associated with a locomotive of the consist, and configured to receive the distributed energy profile for only the locomotive on which it is located and to determine a power configuration of the locomotive based on the distributed energy profile and known parameters of the locomotive, and wherein the operator interface is configured to send unique commands to individual locomotives of the consist.
