Systems and Methods for Autonomous Equipment Operation Where GPS Not Available
First Claim
1. A system for autonomous operation of equipment in an environment inaccessible to global positioning system (GPS) signals, the system comprising:
- a plurality of location controllers configured to be arranged in the environment, at least one of the plurality of location controllers operable to be configured as a master location controller, each one of the location controllers including;
a ranging transmitter/receiver configured to measure controller distance to another one of the location controllers to map the environment, and measure equipment distance to the equipment to determine the equipment'"'"'s location;
a communication transmitter/receiver configured to transmit the measured controller distance to the master controller, and transmit directional commands to the equipment; and
a control module configured to operate the ranging transmitter/receiver and the communication transmitter/receiver;
wherein the master location controller is configured to;
build a map of the environment based on the measured controller distances;
detect entry and exit of the equipment into the environment;
transmit a signal to the communication transmitter/receiver of each one of the plurality of location controllers to notify the plurality of location controllers of the entry and exit of the equipment; and
transmit the map to at least one of the equipment and an equipment control center;
wherein the plurality of location controllers transmit directional commands to the equipment to guide the equipment within the environment.

Abstract
A system for autonomous operation of equipment in an environment inaccessible to GPS. The system includes a plurality of location controllers configured to be arranged in the environment. Each one of the location controllers includes a ranging transmitter/receiver, a communication transmitter/receiver, and a control module. The ranging transmitter/receiver is configured to measure controller distance to another one of the location controllers to map the environment, and measure equipment distance to the equipment to determine the equipment'"'"'s location. The communication transmitter/receiver is configured to transmit the measured controller distance to the master controller, and transmit directional commands to the equipment. A master location controller is configured to build a map of the environment based on the measured controller distances. The plurality of location controllers transmit directional commands to the equipment.

11. A method for autonomous operation of equipment in an environment inaccessible to global positioning system (GPS) signals, the method comprising:
-
arranging a plurality of location controllers about the environment such that each one of the plurality of location controllers is within line of slight of another one of the plurality of location controllers; measuring controller distances between the plurality of location controllers with a ranging transmitter/receiver of each one of the plurality of location controllers; transmitting the controller distances to one of the location controllers configured as a master location controller with a communication transmitter/receiver of each one of the plurality of location controllers; building a map of the environment based on the controller distances transmitted to the master location controller; transmitting the map from the master location controller to at least one of the equipment and an equipment control center; measuring an equipment distance between the equipment and the location controller closest to the equipment with the ranging transmitter/receiver; and transmitting directional commands to the equipment to guide the equipment within the environment. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
