Abstract
A system for controlling a locomotive, including a plurality of portable communications units, each unit adapted to generate signals conveying commands indicative of functions to be performed by the locomotive. Each unit is also associated with an operational status; the signals generated by each unit have a characteristic dependent on the operational status associated with that unit. Also, the system includes a controller adapted to receive the signals generated by the plurality of portable communications units, to determine the commands conveyed by the received signals and to control the locomotive on the basis of the decoded commands. By making each portable transmitter unit aware of its operational status, battery power can be conserved and airwave congestion reduced by precluding the transmission of commands that are guaranteed to be rejected because of the lack of command authority of an originating unit. Meanwhile, the unit which holds command authority continues to be able to send a complete set of commands.
