Abstract

A system for controlling multiple computer directed devices, comprises: a supervisor computer which receives input data serving as operand inputs to a set of logical operators implemented in the supervisor, where the logical operators provide output results; assignable resources, including an m number of planner computers, where m is a positive integer, and an operator station computer; a link server computer; a local area network operably coupled to provide data communications among the supervisor computer, planner computers, operator station computer, and link server computer; and a p number of the devices communicatively linked to the link server computer; wherein the supervisor computer assigns a subset of the assignable resources to direct the operation of at least one of the devices in accordance with the output results.

Claims

1. A system for assigning computer resources to control multiple computer directed devices, comprising:

a p number of autonomous guided vehicles for generating status signals, where p is a positive number;

a link server system for propagating said status signals in response to receiving a query signal;

a supervisor computer for generating assignment signals in response to receiving said status signals from said link server and for generating said query signals;

an m number of planner computers communicatively connected to said supervisor computer and to said autonomous guided Vehicles through said link server system whereby one of said planner computers is selected by said supervisor computer to generate vehicle control signals for directing the operation of a selected one of said autonomous guided vehicles in response to receiving said assignment signals, where m is a positive integer, and p≧

m; and

a local area network operably coupled to provide data communications between said supervisor computer, planner computers, and link server system.

2. The system of claim 1 in which said selected planner computer directs the mobility of said selected autonomous guided vehicle.

3. The system of claim 1 wherein said selected planner computer directs the operation of said selected autonomous guided vehicle if said status signals generated by said selected autonomous vehicle represent an obstacle blocking a path of said selected autonomous guided vehicle.

4. The system of claim 1 wherein said selected planner computer directs the operation of said selected autonomous guided vehicle if said status signals represent that said selected autonomous guided vehicle is lost.

5. The system of claim 1 wherein said selected planner computer directs the operation of said selected autonomous guided vehicle if said status signals represent that said selected autonomous guided vehicle has detected an intrusion in an environment.

6. The system of claim 1 wherein said selected planner computer directs the operation said selected autonomous guided vehicle if said status signals represent that said selected autonomous guided vehicle has a failed diagnostic.

7. A system for assigning computer resources to control multiple computer directed devices, comprising:

a p number of autonomous guided vehicles for generating status signals, where p is a positive number;

a link server system for propagating said status signals in response to receiving a query signal;

a supervisor computer for generating assignment signals in response to receiving said status signals from said link server and for generating said query signals;

an m number of planner computers communicatively connected to said supervisor computer and to said autonomous guided vehicles through said link server system whereby one of said planner computers is selected in response to receiving said assignment signals from said supervisor computer to generate path control signals which direct the mobility of a selected one of said autonomous guided vehicles, where m is a positive integer, and p≧

m;

an n number of operator computers communicatively connected to said supervisor computer and to said autonomous guided vehicles through said link server system whereby one of said operator computers is selected in response to receiving said assignment signals from said supervisor computer to transform manual inputs from a human operator into operator computer generated vehicle control signals for directing the operation of said selected autonomous guided vehicles, where n is a positive integer, and m>

n; and

a local area network operably coupled to provide data communications between said supervisor computer, planner computers, operator computers, and link server system.

8. The system of claim 7 wherein said planner computers and said operator computers are selected in accordance with rules implemented by said supervisor computer.

9. The system of claim 8 wherein one of said planner computers and one of said operator computers are selected according to said rules to control said selected autonomous guided vehicle if a path of said selected autonomous guided vehicle is blocked by a previously undetected obstacle.

10. The system of claim 8 wherein one of said planner computers is selected according to said rules to control said selected autonomous guided vehicle if a path of said selected autonomous guided vehicle is blocked by a previously detected obstacle.

11. The system of claim 8 wherein one of said operator computers are selected according to said rules to control said selected autonomous guided vehicle if a path determined by one of said planner computers is blocked by an obstacle.

12. The system of claim 8 wherein one of said planner computers and one of said operator computers are selected according to said rules to control said selected autonomous guided vehicle if said selected autonomous guided vehicle is lost.

13. The system of claim 8 wherein one of said planner computers and one of said operator computers are selected to control said selected autonomous guided vehicle if said selected autonomous guided vehicle detects a potential intrusion in an environment.

14. The system of claim 8 wherein one of said planner computers and one of said operator computers are selected to control said selected autonomous guided vehicle if said selected autonomous guided vehicle reports a failed diagnostic via said status signals.
