  • Signal error detection in railroad communication system
    Patent number: 7263647
    Abstract: A communication system for a distributed locomotive power/brake control system for a railroad train having a lead locomotive and one or more remote locomotives. Command and status signals are communicated over the system between the lead and remote locomotives. Each communicated message includes an information segment comprising the command or status information, and an error control segment for detecting errors in the information segment. The error control segment further comprises cyclic redundancy code words and parity bits formed according to the horizontal or vertical parity of the information segment and the cyclic redundancy code words.
    Type: Grant

  • Intelligent communications, command, and control system for a land-based vehicle
    Patent number: 6862502
    Abstract: Method and communication system for a railroad train having at least one locomotive for automatically adjusting the communication system to provide effective communication of command data to control operation of the locomotive are provided. The system includes a transceiver on the locomotive. The system further includes at least one transceiver remote from the locomotive. A database may be provided for storing data relative to a plurality of communication schemes available to the communication system. A first monitor may be used for sensing a parameter indicative of the quality of the communications between the transceivers when the transceivers are operating under a first one of the available communication schemes and generating data indicative of communications quality.
