System and method for communicating data in a vehicle system
First Claim
1. A system comprising:
- a router transceiver unit configured to be disposed on-board a vehicle system having at least a source vehicle and a separate linked vehicle that are mechanically linked with each other to travel together along a route and that are communicatively linked with each other through a system network of the vehicle system, the router transceiver unit configured to be communicatively coupled to a requesting operational component of the source vehicle and the system network, the router transceiver unit also configured to receive a local data packet from the requesting operational component that is directed toward a target operational component of the linked vehicle,wherein the local data packet is in a first packet format and the router transceiver unit includes an encapsulation module configured to transform the local data packet that is received by the router transceiver unit from the requesting operational component in the first packet format into an in-tunnel data packet by changing a format of the local data packet from the first packet format to a different, second packet format that is configured to be communicated by the router transceiver unit through the system network to the linked vehicle.

Abstract
A system includes a router transceiver unit that is configured to be disposed on-board a vehicle system. The vehicle system may have at least a source vehicle and a separate linked vehicle that are mechanically linked with each other to travel together along a route and that are communicatively linked with each other through a system network of the vehicle system. The router transceiver unit is configured to be communicatively coupled to a requesting operational component of the source vehicle and the system network. The router transceiver unit is also configured to receive a local data packet from the requesting operational component that is directed toward a target operational component of the linked vehicle. The router transceiver unit includes an encapsulation module that is configured to transform the local data packet into an in-tunnel data packet, where the local and in-tunnel data packets have different packet formats.

9. A system comprising:
-
a router transceiver unit configured to be disposed on-board a vehicle system having at least a source vehicle and a separate linked vehicle that are mechanically linked with each other to travel together along a route and that are communicatively linked with each other through a system network of the vehicle system, the router transceiver unit configured to be communicatively coupled to a target operational component of the linked vehicle and the system network, the router transceiver unit also configured to receive an in-tunnel data packet from a requesting operational component of the source vehicle that is directed toward the target operational component of the linked vehicle, wherein the router transceiver unit includes a translation module configured to transform the in-tunnel data packet that is received from the requesting operational component into a local data packet by changing a packet format of the in-tunnel data packet, the local data packet having a first packet format and the in-tunnel data packet having a second packet format, the first and second packet formats differing from each other. - View Dependent Claims (10, 11, 12, 13, 14, 15, 29)

16. A method comprising:
-
communicatively coupling at least a source vehicle and a separate linked vehicle that are mechanically linked with each other in a vehicle system to travel together along a route, the source vehicle and the separate linked vehicle communicatively linked with each other through a system network of the vehicle system; receiving a local data packet from an operational component of the source vehicle, wherein the local data packet is in a first packet format; and transforming the local data packet into an in-tunnel data packet having a second packet format that differs from the first packet format and that is configured to be communicated through the system network to the linked vehicle. - View Dependent Claims (17, 18, 19, 30)

20. A method comprising:
-
communicatively coupling at least a source vehicle and a separate linked vehicle that are mechanically linked with each other in a vehicle system to travel together along a route, the source vehicle and the separate linked vehicle communicatively coupled with each other through a system network of the vehicle system; receiving an in-tunnel data packet at the linked vehicle, the in-tunnel data packet being sent from the source vehicle of the vehicle system; and transforming the in-tunnel data packet into a local data packet by changing a packet format of the in-tunnel data packet, the local data packet having a first packet format and the in-tunnel data packet having a second packet format that differs from the first packet format, the local data packet configured to be communicated within the linked vehicle to a target operational component, the in-tunnel data packet configured to be communicated between the source and linked vehicles. - View Dependent Claims (21, 22, 31)

23. A method comprising:
-
communicatively coupling first and second linked vehicles that are mechanically linked with each other in a vehicle system to travel together along a route, the first and second linked vehicles being communicatively coupled through a system network of the vehicle system, the first and second linked vehicles having first and second vehicle networks, respectively; communicatively coupling the first vehicle network to a first operational component disposed on-board the first linked vehicle; communicatively coupling the second vehicle network to a second operational component disposed on-board the second linked vehicle, the first operational component a common network address and the second operational component having the same common network address; and assigning first and second in-tunnel addresses that correspond to the first and second operational components, respectively, wherein the first and second in-tunnel addresses are different from each other such that router transceiver units disposed onboard the first and second linked vehicles communicate data between the first and second operational components using the respective first and second in-tunnel addresses. - View Dependent Claims (24, 25, 26, 27)
