摘要： An automated speed control system for a locomotive having a tractive effort mechanism for moving the locomotive along a track and a braking mechanism for reducing the locomotive's speed along the track. The system including a locomotive controller that includes a memory to store computer-executable instructions, and a processor in communication with the memory to execute the instructions to retrieve one or more track grade maps each indicative of a grade of at least a portion of the track along which the locomotive is travelling, retrieve train makeup, obtain a maximum distance to a specified stopping point of the locomotive along the track, and dynamically calculate a speed limit for movement of the locomotive along the track, according to the retrieved track grade map, retrieved train makeup data, and obtained maximum distance to the specified stopping point.

摘要： An example locomotive consist control system includes a locomotive controller located on a locomotive consist to control movement of the locomotive consist along one or more tracks, and a field operator control unit in communication with the locomotive controller. The field operator control unit is configured to control movement of the locomotive consist via the locomotive controller. The system also includes a yard supervisory controller configured to monitor a location of the locomotive consist along the one or more tracks, and a remote operator controller in communication with the yard supervisory controller and the locomotive controller. The remote operator controller is configured to transmit speed and direction orders from the yard supervisory controller to the locomotive controller to control movement of the locomotive consist.

摘要： A membrane digital analog switch includes an input button surface adapted to receive an input pressure from a user, and a digital switch positioned below the input button surface to generate a digital switch activation signal when the received pressure on the input button surface is greater than or equal to a specified digital pressure threshold. The membrane digital analog switch also includes an analog switch adapted to generate an analog switch activation signal when the received pressure on the input button surface is greater than or equal to a specified analog pressure threshold. The specified analog pressure threshold is greater than the specified digital pressure threshold, the digital switch activation signal is a binary digital signal, and the analog switch activation signal is variable and corresponds to an analog sensed value of the received pressure on the input button surface.
