Abstract
Systems and methods for communicating through a rail are provided. In one embodiment, a method for communicating through a rail is provided. The method includes sending an acoustic signal through the rail of a designated section of track. The acoustic signal includes control commands to remotely control operation of a rail vehicle on the designated section of track.
Claims14
A method for communicating through a rail comprising:
- sending an acoustic signal, through the rail of a designated section of track, including control commands to remotely control operation of a rail vehicle on the designated section of track;
- receiving the acoustic signal, through the rail, at the rail vehicle;
- and
- adjusting engine or braking operation of the rail vehicle in response to the received acoustic signal, wherein the acoustic signal is sent from a positionally fixed remote control unit separate from the rail vehicle.
A method for communicating through a rail comprising:
- sending an acoustic signal, through the rail of a designated section of track, including control commands to remotely control operation of a rail vehicle on the designated section of track;
- receiving a feedback acoustic signal, through the rail, from a receiver unit confirming that the rail vehicle is being remotely controlled based on the acoustic signal;
- and
- in response to receiving the feedback acoustic signal, providing an indication to an operator confirming remote control of the rail vehicle.
A method for communicating through a rail comprising:
- sending an acoustic signal, through the rail of a designated section of track, including control commands to remotely control operation of a rail vehicle on the designated section of track, wherein the acoustic signal is sent at a designated frequency or frequency bandwidth corresponding to the designated section of track, and the designated frequency or frequency bandwidth does not correspond to adjacent sections of track.
A method for communicating through a rail comprising:
- sending an acoustic signal, through the rail of a designated section of track, including control commands to remotely control operation of a rail vehicle on the designated section of track;
- receiving a different acoustic signal, at a frequency or frequency bandwidth other than a designated frequency or frequency bandwidth, indicating another rail vehicle has entered the designated section of track;
- and
- in response to receiving the different acoustic signal, sending another acoustic signal, through the rail of the designated section of track, to adjust braking operation of the rail vehicle to accommodate the other rail vehicle.
A communication system comprising:
- a remote control unit, configured for acoustic coupling to a rail of a designated section of track, and to send, through the rail, an acoustic signal to remotely control operation of a rail vehicle on the designated section of track, wherein the remote control unit is positionally fixed, and wherein the positionally fixed remote control unit is further configured to receive acoustic signals through the rail.
A communication system comprising:
- a receiver unit, configured for coupling to a rail vehicle that travels along a rail, the receiver unit comprising a transceiver for receiving an acoustic signal through the rail, and the receiver unit further comprising a control system operably coupled to the transceiver for generating a control signal to adjust an engine or braking operation of the rail vehicle, wherein the control signal is generated by matching a predefined control command that is mapped to the acoustic signal received through the rail.
A method for communicating through a rail comprising:
- receiving an acoustic signal through the rail of a designated section of track from a remote control unit;
- and
- adjusting engine or braking operation of a rail vehicle based on control commands generated from the received acoustic signal.
