Abstract
A system for remotely operating a machine, such as a mine vehicle, includes at least one first emitter for emitting a first signal corresponding to a first zone adjacent to the machine. A transmitter is provided for receiving the first signal emitted by the emitter, the transmitter being adapted for issuing commands for controlling the machine and also indicating the presence of the transmitter in the first zone. A controller is also provided for controlling the machine based on the control signals from the transmitter based on the presence of the transmitter in the first zone. Related methods are also disclosed.
Claims14
A system for remotely operating a machine, comprising:
- a first emitter for emitting a first signal corresponding to a first zone adjacent to the machine;
- a transmitter for receiving the first signal emitted by the first emitter, the transmitter being adapted for issuing commands for controlling the machine and also indicating the presence of the transmitter in the first zone;
- a controller for controlling the machine based on control signals from the transmitter based on the presence of the transmitter in the first zone;
- and
- a second emitter for emitting a second signal corresponding to a second zone adjacent to the machine;
- wherein the controller is adapted for limiting movement of a part movably attached to the machine from a first set of available movements to a smaller subset of said available movements when the transmitter is present within the first zone.
A method of controlling a machine, comprising:
- detecting the presence of a transmitter for transmitting commands for controlling the machine in a particular zone;
- and
- enabling the machine to operate in a predetermined manner based on the detected presence of the transmitter in the particular zone,
- wherein a signal indicative of the particular zone is emitted by the machine;
- wherein the enabling step comprises allowing a part movably attached to the machine to move within a different zone when the transmitter is present in the particular zone;
- wherein the enabling step comprises preventing the part of the machine movably attached to the machine from moving to or within the particular zone when the transmitter is present therein.

- a controller for controlling the machine based on control signals from the transmitter based on the presence of the transmitter in the first zone;
- and
- a second emitter for emitting a second signal corresponding to a second zone adjacent to the machine;
- wherein the controller is adapted for preventing any part of the machine from moving to the first zone when the transmitter is indicated therein.
