Determination of remote control operator position
First Claim
1. A system for controlling operation of a work machine, the system comprising:
- a signal system, positionable at a remote location from the work machine, comprising;
a signal generator adapted to generate a control signal;
a controller assembly supported by the work machine comprising;
a receiver assembly adapted to detect the control signal from the signal generator;
a processor adapted to determine a location of the signal system relative to the receiver assembly using the detected control signal and to change an operational characteristic of the work machine based upon either the control signal or the determined location of the signal system relative to the receiver assembly.

Abstract
A system for controlling a work machine and work tool from a remote controller. The remote controller sends a control signal to a receiver assembly and machine controller. The machine controller processes the control signal to determine the location of the remote controller relative to the receiver assembly and to alter operational characteristics of the machine or work tool based on the control signal or the location of the remote controller relative to the receiver assembly. The system may include a tag system to detect the presence of workers at the jobsite and to alter operation of the machine and work tool based upon the location of the workers relative to the machine or work tool. In another embodiment, a signal may be transmitted from the work machine and detected by a remote receiver assembly. A processor uses the detected signal to determine the position of the remote receiver assembly relative to the work machine.
