Patent Images
1. A system comprising:
- a router transceiver unit having an electrical output and communication circuitry coupled to the electrical output and configured for communication across at least one first communication channel of a first vehicle of a vehicle consist and at least one second communication channel of at least a second vehicle of the vehicle consist;
wherein the router transceiver unit is configured for electrical attachment of the electrical output to an inter-vehicle infrastructure of the vehicle consist;
wherein the router transceiver unit is further configured for routing data onboard the vehicle consist through the at least one first communication channel and the at least one second communication channel in dependence upon respective determined operational statuses of the at least one first communication channel and the at least one second communication channel; and
wherein the router transceiver unit is configured for the at least one first communication channel and the at least one second communication channel to simultaneously function over said inter-vehicle infrastructure.

17. A system comprising:
-
a controller configured to be disposed onboard a first vehicle in a vehicle consist that includes the first vehicle and one or more remote vehicles, the controller configured to remotely control operation of the one or more remote vehicles to control movement of the vehicle consist; and a brake sensing device configured to be disposed onboard the vehicle consist and to measure characteristic of an air brake system of the vehicle consist, wherein the controller is configured to store the characteristic of the air brake system that is measured by the brake sensing device and to communicate over at least two logically distinct networks that share an individual infrastructure the characteristic of the air brake system to at least one of the remote vehicles for storage onboard the at least one of the remote vehicles, and wherein, responsive to a fault at the controller that causes loss of the characteristic of the air brake system at the controller, the controller is configured to receive over the at least two logically distinct networks that share an individual infrastructure, from the at least one of the remote vehicles, the characteristic of the air brake system that was communicated from the controller to the at least one of the remote vehicles. - View Dependent Claims (18, 19, 20)
