Method and system for providing redundancy in railroad communication equipment

摘要

A railway communication system ( 10 ) includes a transmitter ( 12 ) receiving an input and producing a communication signal ( 18 ). The communication signal ( 18 ) includes at least two different portions ( 20,22 ) for separately encoding respective indications ( 38,40 ) of the input. The system also includes a receiver ( 14 ) coupled to a controlled device, the receiver ( 14 ) extracting at least one of the respective indications ( 38,40 ) from the communication signal ( 18 ). The receiver controls the device responsive to the at least one extracted indications ( 38,40 ).
