Abstract
A portable master controller for a locomotive remote control system is provided including a user interface, a tilt sensor, a processing unit and a transmission unit. The user interface is receives commands to control a movement of the locomotive from a human operator and generates a control signal on the basis of the commands. The tilt sensor generates inclination information about the portable master controller. The processing unit generates a digital command signal that includes a first component derived from the control signal received from the user interface and a second component derived from the inclination information received from the tilt sensor. The second component of the digital command signal allows a slave controller to determine whether the portable master controller is in an unsafe operational condition. The transmission unit then generates a RF transmission for conveying the digital command signal to a slave controller.
