摘要:
A method for communicating data in a rail vehicle consist includes transmitting first data at a first rail vehicle of the consist over a power supply conductor to a second, different rail vehicle in the consist, where at least one rail vehicle of the consist receives direct electrical power from the power supply conductor. The method also includes monitoring the power supply conductor for second data at the first rail vehicle and receiving the second data over the power supply conductor at the first rail vehicle for use by a first system onboard the first rail vehicle. In one aspect, the transmitting step comprises transmitting the first data over one or more of a catenary line or a third rail that supplies the electrical power.

A method for communicating data in a rail vehicle consist includes transmitting, at a first rail vehicle in the consist, first data over a running rail to a second, different rail vehicle in the consist, where the running rail guides and supports the rail vehicles of the consist as the rail vehicles travel along the running rail. The method also includes monitoring the running rail for second data and receiving the second data over the running rail for use by a first system onboard the first rail vehicle.

摘要:
Method and communication system for a railroad train having at least one locomotive for automatically adjusting the communication system to provide effective communication of command data to control operation of the locomotive are provided. The system includes a transceiver on the locomotive. The system further includes at least one transceiver remote from the locomotive. A database may be provided for storing data relative to a plurality of communication schemes available to the communication system. A first monitor may be used for sensing a parameter indicative of the quality of the communications between the transceivers when the transceivers are operating under a first one of the available communication schemes and generating data indicative of communications quality. A processor in communication-with the monitor and the database may be configured to select a second communication scheme when the quality of the communications provided by the first communication scheme is not satisfactory to ensure that the command data will be reliably communicated with respect to the locomotive.
摘要:
A passenger vehicle consist includes a plurality of passenger vehicles and an electrical power transmission line interconnecting the plurality of passenger vehicles. A system for communicating data in the vehicle consist includes first unit on a first vehicle in the consist and a second unit on a second vehicle in the consist. The first and second units are electrically coupled to an electrical power transmission line in the consist that interconnections adjacent vehicles. The electrical power transmission line is an existing line used in the vehicle consist for transferring electrical power to the vehicles in the consist. The first and second units are configured to transmit and/or receive at least one of high-bandwidth data or network data over the electrical power transmission line.

A system includes a first propulsion subsystem and a second propulsion subsystem. The first propulsion subsystem is operable to provide electrical energy to a first communication device when operating in an ON mode. The second propulsion subsystem is operable to provide electrical energy to a second communication device when operating in the ON mode. The first propulsion subsystem and the second propulsion subsystem are controllable in a mode of operation where if one of the first propulsion subsystem or the second propulsion subsystem is controlled to be in an OFF mode, the other of the first propulsion subsystem and the second propulsion subsystem provides electrical energy to the respective first communication device or the second communication device.

摘要:
A distributed power train (10) communications system for sending and receiving signals between a lead locomotive (14) and remote locomotives (12A/12B/12C) in the train (10). A lead (14) initiated message is received by at least the remote locomotive (12A/12B) nearest to the lead unit (14). The receiving remote unit (12A/12B) retransmits the message for receiving by the next remote unit (12C) in the train. Thus the message leapfrogs down the train from the lead unit (14) to the remote units (12A/12B/12C). When the last remote unit (the nth remote unit) (12C) receives the message, the last remote (12C) transmits a status or other response message to the lead unit's message. The status message is received at the (n-1)th remote unit (12A/12B), which appends its status message and transmits the combined status messages toward the lead unit (14). Each successive remote unit receives the status messages of the other remote units and appends its status message, until the concatenated status message reaches the lead unit (14).
摘要:
A method of controlling a neutral section operation of a train (14) including a lead locomotive (16) and at least one remote locomotive (12) in communication with the lead locomotive. The locomotives are electrically powered from respective electrical connections to a catenary (22) having at least one neutral section (26). The method includes sensing when a lead locomotive is proximate the neutral section of the catenary. The lead locomotive then commands the remote locomotive to perform a neutral section operation when the lead locomotive has traveled a distance equal to a distance (20) between the lead locomotive and the remote locomotive. The lead locomotive determines when to issue a neutral section command based on a speed of the lead locomotive and an elapsed time from when the lead locomotive senses its location proximate the neutral section.
