Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.

Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A system and a method includes one or more processors to control operation of an air brake system having plural braking devices each disposed on a different vehicle of a vehicle system and configured to control braking efforts in the air brake system via the braking device disposed onboard the corresponding vehicle. The one or more processors may communicate one or more command messages to the braking devices to control one or more of a rate of a braking effort propagation along the vehicle system or a direction of the braking effort propagation between the plural braking devices.

Abstract: A system and a method includes a monitoring device disposed onboard a first vehicle of a vehicle system. The monitoring device may obtain information about one or more of the monitoring device, the first vehicle, the vehicle system, or a route along which the vehicle system moves. The system includes a communication system having one or more processors configured to wirelessly activate and communicate with the monitoring device. The communication system is configured to wirelessly activate the monitoring device by controlling the monitoring device to establish a communication link between the monitoring device and a control system disposed onboard another vehicle of the vehicle system. The communication system is separate from and disposed a distance away from the monitoring device and the vehicle system.

CPC classification number: H04W4/46
Abstract: A communication system may include communication devices configured to be onboard vehicles in a multi-vehicle system. Each of the communication devices may operate in a lead mode, a repeater mode, or a trail mode. The communication devices operating in the lead mode may transmit a command signal to control movement of the multi-vehicle system. The communication devices operating in the repeater mode may re-transmit the command signal received from the one or more communication devices operating in the lead mode. The communication devices operating in the trail mode may receive the command signal received from the one or more communication devices operating in the lead mode or in the repeater mode. Each of the communication devices may be remotely switched between the lead mode or the trail mode to the repeater mode.

Abstract: A system may be provided that includes a first power source configured to supply power to a communication system of a vehicle system to communicate a signal from a first vehicle of the vehicle system to a second vehicle of the vehicle system. The system may include a second power source configured to supply power to the communication system to communicate the signal from the first vehicle to the second vehicle, and a controller. The controller may obtain an operational parameter, and communicate the signal based on the operational parameter when the first power source supplies power to the communication system. The controller may be configured to communicate the signal utilizing the power from the second power source based on the operational parameter when the first power source does not supply power to the communication system.

Abstract: A communication device and method may include at least one tuner circuit that monitors at least a first frequency channel and a second frequency channel. A controller of the radio receiver may measure a first received signal strength indicator (RSSI) value over time for the first frequency channel and a second RSSI value over time for the second frequency channel. The first and second RSSI values are based on a signal strength of radio frequency (RF) energy received on the first and second frequency channels, respectively. The controller may detect a leader portion of a message on the first frequency channel responsive to a change in the first RSSI value exceeding a step change threshold. The controller may extract, via a detector circuit, message data from a carrier wave of the RF message.
