Abstract

An AGV for transporting material between at least two pickup and delivery stands. The AGV has a chassis for carrying objects. A computer processor is supported by the chassis for controlling and monitoring AGV operation. An interactive display is connected to the computer processor and mounted on the chassis for displaying status, current assignment and diagnostic information relating to AGV operation.

Claims

1. An automatic guided vehicle (AGV) for transporting material between at least two pickup and delivery stands within a warehouse-type facility, said automatic guided vehicle (AGV) being part of a hierarchial traffic control and routing system comprising:

a) a chassis adapted to carry material;

b) information processing means carried by, and integrally disposed upon said chassis for controlling and monitoring AGV operation upon said chassis including the routing thereof; and

c) an interactive display including a CRT screen operatively connected to said information processing means and supported by said chassis, said CRT screen of said interactive display having means for simultaneously displaying both diagnostic and routing information thereon, said diagnostic information being menu controllable via said information processing means, and said display and information processing means being operative to display said diagnostic information in analog, digital and graphical format.

2. The AGV in accordance with claim 1 further comprising:

d) diagnostic means for interrogating internal conditions of the AGV, and wherein disagnostic information comprises alphanumeric characters.

3. The AGV in accordance with claim 2 wherein said diagnostic information comprises graphic representation.

4. The AGV in accordance with claim 2 wherein said diagnostic information is displayed in menu driven form.

5. The AGV in accordance with claim 4 further comprising:

d) alarm signal generating means operatively connected to said information processing means for indicating a condition of said AGV.

6. The AGV in accordance with claim 5 wherein said alarm signal generating means generates an audible signal.

7. The AGV in accordance with claim 6 wherein said alarm signal generating means comprises a tone generator.

8. The AGV in accordance with claim 6 wherein said alarm signal generating means comprises a speech synthesizer.

9. The AGV in accordance with claim 5 further comprising:

e) a manual controller for interrogating said information processing means.

10. The AGV in accordance with claim 9 wherein said alarm signal generating means comprises a speech synthesizer.

11. The AGV in accordance with claim 5 wherein said alarm signal generating means comprises a speech synthesizer.

12. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of battery voltage.

13. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of objects in the path of said AGV.

14. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of objects in physical contact with said AGV.

15. The AGV in accordance with claim 5 further comprising:

d) a modem operatively connected to said information processing means for facilitating communication between said information processing means and a remote device.

16. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of status of an AGV subsystem.

17. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of steering assembly operation.

18. The AGV in accordance with claim 5 wherein said diagnostic information comprises information indicative of guidance control system operation.

19. The AGV in accordance with claim 2 wherein said information processing means comprises a computer having a central processing unit.

20. The AGV in accordance with claim 2 further comprising:

d) a manual controller for interrogating said information processing means.

21. The AGV in accordance with claim 20 wherein said alarm signal generating means comprises a speech synthesizer.

22. The AGV in accordance with claim 1 further comprising:

d) a modem operatively connected to said information processing means for facilitating communication between said information processing means and a remote device.

23. An interactive diagnostic subsystem for use upon a chassis of an automatic guided vehicle (AGV) being guided through a warehouse according to a facility floor plan and which is part of a hierarchial routing and traffic control system, comprising:

a) information processing means for monitoring a plurality of AGV operating conditions;

b) an interactive display means including a CRT screen operatively connected to said information processing means for displaying information in analog, digital and graphical format; and

c) means operatively connected to said information processing means and to said display means for updating information displayed thereon responsive to changes in one of said plurality of AGV operating conditions.

24. The interactive diagnostic subsystem in accordance with claim 23 wherein operational information comprises alphanumeric characters.

25. The interactive diagnostic subsystem in accordance with claim 24 further comprising:

d) alarm signal generating means operatively connected to said information processing means for indicating one of said plurality of AGV conditions.

26. The interactive diagnostic subsystem in accordance with claim 24 further comprising:

d) interrogating means operatively connected to said information processing means for generating responses on said display means for simultaneous display of at least two of said plurality of AGV operating conditions.

27. The interactive diagnostic subsystem in accordance with claim 24 wherein said diagnostic information comprises information indicative of battery voltage.

28. The interactive diagnostic subsystem in accordance with claim 24 wherein said diagnostic information comprises information indicative of objects in the path of said AGV.

29. The interactive diagnostic subsystem in accordance with claim 24 wherein said diagnostic information comprises information indicative of objects in physical contact with said AGV.

30. The interactive diagnostic subsystem in accordance with claim 24 wherein said diagnostic information comprises information indicative of status of an AGV subsystem.

31. The interactive diagnostic subsystem in accordance with claim 24 wherein said diagnostic information comprises information indicative of steering assembly operation.
