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.

Remote control system for a locomotive with tilt sensor

A portable master controller for a locomotive remote control system. The portable master controller has a user interface for receiving commands to control the movement of the locomotive. The user interface is responsive to operator commands to generate control signals. A processing unit receives the control signals from the user interface to generate digital command signals directing the movement of the locomotive. A transmission unit receives the digital command signals and generates a RF transmission conveying the digital command signals to the slave controller. A solid-state tilt sensor in communication with the processing unit communicates inclination information to the processing unit about the portable master controller. The processing unit receives and processes the inclination information. If the inclination information indicates that the portable master controller is in an unsafe operational condition, the processing unit generates an emergency digital command signal to the transmission unit, without input from the operator, for directing the locomotive to acquire a secure condition.
