Determination of remote control operator position

摘要

A system and method for controlling a work machine system having a work machine and work tool. Operational characteristics of both the work machine and work tool are configured by a machine controller based upon the type of work tool attached to the work machine, the operating environment of the work machine, and the location of work site personnel or other observers relative to the machine or work tool. The operational characteristics of both the work machine and work tool may then be automatically altered during operation of the work machine system to limit or expand functions of the work machine system in response to changes in the operational environment or movement of personnel or observers relative to the work machine system.

1. A system for controlling operation of a work machine having a work tool, the system comprising:
an attachment sensor to determine attachment of the work tool and to determine the type of work tool operatively connected to the work machine; a controller assembly supported by the work machine to generate control signals used for operation of the work machine and the work tool; a remote control system relative to the work machine comprising a signal system; an antenna assembly supported by the work machine to establish an operational boundary around the work machine and work tool and to transmit a personnel detection signal; wherein the operational boundary is defined by the location of the remote control system, the work tool, and the work machine; and a processing assembly to configure the controller assembly for operation of the work tool detected by the attachment sensor, to determine a location of personnel relative to the operational boundary and to periodically alter the control signal output by the controller system to change an operational characteristic of the work tool based upon a detected location of personnel relative to the operational boundary.
