SERIAL TRAIN COMMUNICATION SYSTEM

摘要

A serial train communication system employs a pair of ultrasonic tranceivers oppositely mounted at each end of railway car. Each ultrasonic transceiver is coupled to a controller and to an independent power source. The controller is further coupled to various apparatuses installed on the railway car and is capable of controlling operation thereof. A command signal sent from a locomotive cab travels between railway cars enabling control various apparatuses of such railway cars and status signals from such apparatuses may be attached to the railway car or to any such apparatus. In another embodiment, a single ultrasonic transceiver is insalled within an air brake pipe enabling communication within a mixed railway car configuration.
