Abstract

A system and method for a remote calling system for an automatic guided vehicle is disclosed herein. The remote calling system is configured to receive a destination request from an operator located at a remote location. The remote calling system is further configured to check the availability of the automatic guided vehicle at each of the parking lots. When at least one automatic guided vehicle is available at a parking lot, the remote calling system transmits the destination request to that parking lot. The remote calling system utilizes a telephone communication system.

2. The method of claim 1, wherein the transmitting step includes transmitting the destination request from a controller at the second location to a receiver included in the automatic guided vehicle at the second location, thereby activating the automatic guided vehicle for travel to a destination specified in the received destination request.

3. The method of claim 1, further comprising storing the destination request before the transmitting step when the checking step indicates that no automatic guided vehicle is present at the second location.

4. The method of claim 3, wherein the storing step includes storing a plurality of destination requests in accordance with the communicating step being repeated a plurality of times.

5. The method of claim 4, wherein transmitting the destination request includes transmitting each of the stored plurality of destination requests on a first-in first-out basis.

6. The method of claim 4, further comprising processing the plurality of destination requests based on one or more criterions to facilitate efficient use of the automatic guided vehicle, and wherein transmitting the destination request includes transmitting the plurality of destination requests as dictated by the processing step.

7. The method of claim 1, further comprising connecting a remote destination request system at the second location to the telephone communication system when an operator at the first location initiates a connection request.

8. The method of claim 1, further comprising communicating at least one instruction from the second location to an operator at the first location, the at least one instruction selected from a group including a password prompt instruction, a destination request instruction, a destination verification instruction, and an end communication instruction, and the operator at the first location communicating a security access code to the second location before communicating the destination request to the second location.

9. The method of claim 1 wherein the automated guided vehicle includes a controller, wherein the controller receives incoming information from and transmits outgoing information to an operator at a remote location via a telephone communication system, wherein the controller includes a dial tone multifrequency (DTMF) detector and a processor to receive incoming information from the operator, wherein the DTMF detector is coupled to the telephone communication system and the processor is coupled to the DTMF detector.

11. The system of claim 9, wherein the controller includes a call detector coupled to a processor, the call detector configured to be responsive to incoming and outgoing information.

12. The system of claim 11, wherein the operator requests an initial connection to the controller, the call detector transmits the initial connection request to the processor, and the processor instructs a relay unit to connect the controller to the telephone communication system, wherein the relay unit is coupled to the call detector and to the processor.

10. A remote destination instruction system of an automatic guided vehicle system, comprising:

a controller configured to receive incoming information from an operator located at a remote location, transmit outgoing information to the operator, and communicate with an automatic guided vehicle present at a parking lot of the automatic guided vehicle system to fulfill a destination request received from the operator;

wherein the controller receives incoming information from and transmits outgoing information to the operator at the remote location via a telephone communication system; and

wherein the controller includes a dial tone multifrequency (DTMF) detector and a processor to receive incoming information from the operator, wherein the DTMF detector is coupled to the telephone communication system and the processor is coupled to he DTMF detector.

13. The system of claim 10, wherein the controller includes a call detector and a relay unit, the call detector coupled to the relay unit and the relay unit coupled to the DTMF detector.

14. The system of claim 10, wherein the DTMF detector is configured to generate digital signal appropriate for the processor and representative of the incoming information, the incoming information representative of the operator'"'"'s inputs to the telephone communication system.

15. The system of claim 10, wherein the controller includes an auto voice messenger, a coupling transformer, and a processor to transmit outgoing information to the operator, wherein the coupling transformer is coupled to the telephone communication system and the auto voice messenger, and the auto voice messenger is coupled to the processor.

16. The system of claim 15, wherein the controller includes a call detector and a relay unit, the call detector coupled to the relay unit and the relay unit coupled to the coupling transformer.
