METHOD AND APPARATUS FOR USING A REMOTE DISTRIBUTED POWER LOCOMOTIVE AS A REPEATER IN THE COMMUNICATIONS LINK BETWEEN A HEAD-OF-TRAIN DEVICE AND AN END-OF-TRAIN DEVICE

摘要

Proposed is a method of communicating messages between an HOT device (48L) in a lead locomotive (14) and an EOT device (40) at an end-of-train position. The method comprises tuning a DP transceiver (28L) onboard a remote locomotive (12A) to an HOT/EOT communications channel frequency, transmitting a message from the EOT device (40) intended for the HOT device (48L) or transmitting a message from the HOT device (48L) intended for the EOT device (40), and receiving the message at the DP transceiver (28L). If the message was transmitted from EOT device (40), transmitting the message from the DP transceiver (28L) to HOT device (48L) and receiving and executing the message at the HOT device (48L) is performed. If the message was transmitted from the HOT device (48L), transmitting the message from the DP transceiver (28L) to the FOT device (40) and receiving and executing the message at the EOT device (40) is performed.
