Abstract

The present disclosure is directed to a distributed control system for a locomotive. The distributed system may include a network and a plurality of electronic modules distributed within a locomotive. Each of the electronic modules is communicatively coupled to the network in a standardized scalable architecture. Each of the electronic modules may include at least a configurable controller that is reconfigurable to implement at least one control function associated with distributed control of the locomotive.

Claims

1. A distributed control system for a locomotive, comprising:

a network disposed within the locomotive; and

a plurality of electronic modules spatially distributed within the locomotive, each of the electronic modules communicatively coupled to the network in a standardized scalable architecture,

wherein each of the electronic modules comprises at least a configurable controller that is reconfigurable to implement distributed control of the locomotive.

2. The distributed control system of claim 1, wherein the configurable controller is configured to implement at least one of a plurality of control functions associated with the distributed control of the locomotive.

3. The distributed control system of claim 1, wherein at least one of the electronic modules further includes a programmable controller in communication with each of the configurable controller and the network, the programmable controller being removably connected to the electronic module, and wherein the configurable controller is communicatively connected to one or more control elements disposed within the locomotive.

4. The distributed control system of claim 3, wherein the programmable controller is adapted to provide computational support for a control function associated with the at least one of the electronic modules, the control function being at least one of a plurality of control functions associated with the distributed control of the locomotive.

5. The distributed control system of claim 4, wherein the configurable controller includes logic gates that may be reconfigured in how the logic gates are interconnected when providing analog or digital control that implements the control function relative to the one or more control elements.

6. The distributed control system of claim 3, wherein the programmable controller is a programmatically controlled device implemented by at least one of a microprocessor, a microcontroller, and a system-on-module.

7. The distributed control system of claim 1, wherein the configurable controller is a reconfigurable device implemented by a field programmable gate array.

8. The distributed control system of claim 1, wherein each one of the plurality of electronic modules is configured to host a plurality of software applications, and when a consumption of processing capacity of a first electronic module exceeds a threshold value, the first electronic module is configured to offload a subset of its software applications to a second electronic module.

9. The distributed control system of claim 3, wherein the one or more control elements include at least one of a sensor, an actuator, a communication device, a navigation device, and a human-to-machine interface device, and the human-to-machine interface device being at least one from a group consisting of a monitor, a light emitting diode, an indicator, a switch, a button, a keypad, a keyboard, a touchpad, a joystick, a speaker, a microphone, and a credential reader.

10. The distributed control system of claim 1, wherein at least one of the electronic modules further includes:

a standardized main board on which the configurable controller is formed; and

at least one daughter board connected to the main board via a communication port, the daughter board includes one or more I/O ports to be connected to one or more control elements spatially distributed within the locomotive,

the configurable controller being configured to communicate with the one or more control elements via the one or more I/O ports.

11. A method for controlling a locomotive, the method comprising:

receiving a message by a first of a plurality of electronic modules coupled to a network disposed within the locomotive, each of the electronic modules spatially distributed within the locomotive and operatively coupled to the network in a standardized scalable architecture;

processing the message by a programmable controller or a configurable controller in the first of the electronic modules to identify a first control command;

based upon the identified first control command, generating a control signal by the configurable controller, the control signal associated with at least one of a plurality of control functions as part of distributed control of the locomotive; and

applying the generated control signal to one or more control elements disposed within the locomotive.

12. The method of claim 11, further including operatively monitoring the one or more control elements using the configurable controller.

13. The method of claim 12, further including receiving a monitored locomotive signal from the one or more control elements.

14. The method of claim 13, further including processing the monitored locomotive signal within the first of the electronic modules and altering the generated control signal applied to the one or more control elements disposed within the locomotive.
