Abstract:
In a communication system and method, a vehicle identifier is determined for a first remote vehicle that is included in a vehicle consist formed from a lead vehicle and at least the first remote vehicle. The system and method communicate a wireless linking message addressed to the vehicle identifier from the lead vehicle to the first remote vehicle, and establish a communication link between the lead vehicle and the first remote vehicle responsive to receipt of the wireless linking message at the first remote vehicle. The communication link is established such that movement of the first remote vehicle is remotely controlled from the lead vehicle via the communication link. The communication link is established without an operator entering the first remote vehicle.
Abstract:
A communication system includes a first wireless communication device disposed onboard a vehicle system having two or more propulsion-generating vehicles that are mechanically interconnected with each other. The communication system also includes a controller configured to be disposed onboard the vehicle system and operatively connected with the first wireless communication device in order to control operations of the device. The controller is configured to direct the first wireless communication device to switch between operating in an off-board communication mode and an onboard communication mode. When the first wireless communication device is operating in the off-board communication mode, the device is configured to receive remote data signals from a location that is disposed off-board of the vehicle system. When the first wireless communication device is operating in the onboard communication mode, the device is configured to communicate local data signals between the propulsion-generating vehicles of the vehicle system.
Abstract:
A communication system and method receive, at an energy management system disposed onboard a vehicle system formed from a lead vehicle and one or more remote vehicles, trip data that represents one or more characteristics of an upcoming trip of the vehicle system along a route. A selected portion of the trip data is communicated from the energy management system to a distributed power system also disposed onboard the vehicle system. The selected portion includes identifying information and one or more orientations of the one or more remote vehicles. Using the distributed power system, communication links between the lead vehicle and the one or more remote vehicles are established using the identifying information and the one or more orientations.
Abstract:
A brake monitoring system and method determine one or more characteristics of a conduit in a first air brake system of a first vehicle system, compare the one or more characteristics of the first air brake system with one or more designated waveform signatures, and distinguish between communication of a brake application signal that is propagated along the vehicle system through the conduit as a decrease in pressure in the conduit and a change in the pressure in the conduit that is not representative of the communication of the brake application signal based on comparing the one or more characteristics with the one or more designated waveform signatures.
Abstract:
A synchronizing system and method receive event log data from different monitoring systems. The event log data represents operational events of a powered system recorded by the monitoring systems and corresponding times of the operational events. The monitoring systems record the event log data at different time bases and/or sampling rates. The event log data from the monitoring systems are temporally correlated with each other by changing the time bases of the event log data to a common time base and/or by changing a visual presentation of the event log data such that the event log data are visually presented with a common time scale responsive to the sampling rates differing from each other.
Abstract:
A method and system for converting protocols of messages receive a first wireless message onboard a first vehicle in a vehicle consist that includes the first vehicle and one or more additional vehicles. The method and system also determine a first protocol of the first wireless message, determine a different, second protocol used by a control system disposed onboard the first vehicle, change the first wireless message to a different, second message by modifying the first protocol of the first wireless message to the different, second protocol, and communicate the second message to the control system.
Abstract:
A locomotive communication system includes a wireless communication device and a controller that controls operation of the wireless communication device. The controller directs the wireless communication device to switch between operating in an off-board communication mode and operating in an onboard communication mode. The wireless communication device communicates a remote data signal with an off-board location while the wireless communication device is operating in the off-board communication mode and the wireless communication device communicates a local data signal between the propulsion-generating vehicles of the vehicle system while the wireless communication device is operating in the onboard communication mode.

The communication link is established such that movement of the first remote vehicle is remotely controlled from the lead vehicle via the communication link. The communication link is established without an operator entering the first remote vehicle.
Abstract:
Communication methods and systems wirelessly communicate onboard messages between communication devices onboard the same vehicle. The communication devices can wirelessly communicate with other communication devices onboard other vehicles in a vehicle system for remote control of the vehicles. Receipt of the onboard messages at the communication devices is determined, and operative states of the communication devices are determined based at least in part on the receipt of the onboard messages at the communication devices. Determining these operative states in this manner can allow for an operator to identify communication faults with the communication devices prior to departing the vehicle.
