Remote control for a drilling machine

摘要

A method and apparatus for remotely controlling a machine. A remote operator controls a tracking device including a signal system for selectively emitting a remote enable signal. The remote enable signal is relayed to a control system for the machine. The control system is proximate to the machine and is adapted to enable at least one action of the machine upon detecting the remote enable signal. The machine is also adapted to disable the same action of the drilling machine upon detecting an absence of the remote enable signal for a predetermined number of intervals, each interval being of a preselected duration.
