Abstract:
A communication system (10) for a distributed locomotive power communications system for a railroad train having a lead locomotive (14) and one or more remote locomotives (12, 13). Messages are communicated over the system between the lead (14) and remote (12, 13) locomotives. Each communicated message includes information bits (41) and an error detection bits (42, 43, 44) for detecting errors in the information bits (41). The error detection bits (42, 43, 44) further comprise cyclic redundancy code words and parity bits formed according to the horizontal (43) or vertical (44) parity of the information bits (41) and the cyclic redundancy code words (42).
Abstract:
A detection system for a rail vehicle includes a control module, which has a sensor input for receiving a signal from a sensor. The control module is configured to receive the signal and to output information responsive to the signal. In operation, the control module and a sensor are deployed on board the rail vehicle. The sensor is configured to generate the signal responsive to detecting a designated condition on board the rail vehicle. When the condition occurs, the sensor outputs the signal, which is received by the control module. Responsive to the signal, the control module outputs the information, such as communicating information of the signal content to another rail vehicle, or to an off board location. The designated condition may be unauthorized use of a handheld wireless device in a rail vehicle, or intruder entry into an unmanned rail vehicle.
Abstract:
A data communication system (100, 600) for a rail vehicle (102, 602) includes a processing module (122, 618) that is configured to interface with the rail vehicle (102, 602) and with a data reading device (120, 616). The data reading device ( 120, 616) is configured to at least one of electromagnetically interrogate or optically read data that is visually presented on a tangible and non- transitory medium (104, 128, 612, 630). The tangible and non-transitory medium (104, 128, 612, 630) is spaced apart from the data reading device (120, 616}. The processing module ( 122, 618) is configured to receive the data from the data reading device (120, 616) and to use the data in connection with one or more operations of the rail vehicle (102, 602).
