System, method, and computer software code for providing an auxiliary communication path when a primary communication path is unavailable

摘要

A method for communicating on a train that has at least two locomotives, the method including determining when a primary communication path ceases to be available for a specific subsystem of the train, identifying at least one auxiliary communication path to transmit information for the specific subsystem, configuring a message for the specific subsystem which complies with a message format of the at least one auxiliary communication path, and transmitting the message on the at least one auxiliary communication path. A system and a computer software code are further disclosed for providing a communication system for a powered system.

1. A method comprising:
determining when a first communication path ceases to be available for communication of a message used by a first subsystem of a vehicle to control one or more operations of the vehicle; identifying a different, second communication path of a different, second subsystem of the vehicle, the first communication path and the second communication path being different from each other in that the first communication path uses a first message format to communicate information for the first subsystem and the second communication path uses a different, second communication format to communicate information for the second subsystem; reformatting the message from the first format of the first communication path and the first subsystem to the second format of the second communication path and the second subsystem, wherein the first format of the first subsystem is incompatible with the second format of the second subsystem; transmitting the message in the second format on the second communication path; and transitioning back to the first communication path for communication of a subsequent message for the first subsystem when the first communication path is again available for communication of the subsequent message.
