Abstract
A method and system for tracking and limiting the movement of key identified points on a movable machine, through the use of location devices positioned on the body or appendages of the machine, by comparing the sensed locations against a database of site information, and to restrict movement of the machine and/or its appendages if it has or is likely to pass through a defined boundary in the site information database.
Claims29
A system for controlling the movement of mobile machines, comprising:
- a control system in communication with an operator-driven operating system of a mobile machine;
- a location system in communication with said control system, wherein said location system comprises a plurality of global location detectors positioned at one or more location points on a mobile machine corresponding to key points of the machine;
- and
- wherein said control system contains data of one or more limit boundaries for determining when one or more key points of a mobile machine are imminently about to intersect with one or more said limit boundaries and overrides the operator commands to the operating system to modify movement of the mobile machine to prevent exceeding one or more said limit boundaries.

A method for controlling the movement of mobile machines, comprising:
- providing a mobile machine having an operator-driven operating system for effecting movement of a portion of said mobile machine with relative to a design mesh;
- providing a control system;
- providing a location system comprising global location detectors corresponding to key points on said mobile machine and local location detectors for determining the location of said key points locally, said global and local location detectors being in communication with said control system;
- inputting into said control system data comprising a design mesh having defined limit boundaries;
- continuously monitoring said global location detectors and said local location detectors corresponding to said key points on said mobile machine;
- determining when said mobile machine is approaching an intersection with said defined limit boundaries of said design mesh;
- and
- overriding the operator commands given to the operating system of said mobile machine to modify the movement of said appendage of said machine to prevent said appendage from exceeding the defined limit boundaries of said design mesh.
