Abstract

A system and method for remotely controlling loading dock components is disclosed that includes a distribution center having at least one dock station for exchanging materials and a dock component configured to in at least two operational states. An actuator is included that is configured to change the operational state of the dock component in response to an activation signal. A mobile remote control is configured to generate the activation signal to cause the actuator to change the operational state of the dock component and at least one predefined non-activation zone is included such that changing of operational state of the dock component is inhibited when the mobile remote control is located within the at least one predefined non-activation zone.

First claim

What is claimed is:

1. A dock control system comprising:
a camera for mounting on a docking station, the camera configured to obtain at least one image of a vehicle restraint system of the docking station;
a graphical user interface configured to display the at least one image of the vehicle restraint system to an operator of the docking station to verify if a vehicle has been restrained; and
a controller configured to:
receive the at least one image of the vehicle restraint system from the camera;
transmit the at least one image of the vehicle restraint system to the graphical user interface; and
receive verification that a vehicle has been restrained from an operator of the docking station via the graphical user interface.

2. The dock control system of claim 1 wherein the at least one image of the vehicle restraint system comprises a video and/or a still image.

3. The dock control system of claim 1 wherein the graphical user interface is further configured to allow an operator of the docking station to change an operational state of a component of the docking station after verifying that a vehicle has been restrained.

4. The dock control system of claim 1 wherein the vehicle restraint system comprises a restraint selected from one or more of the following types: rear impact guard (RIG) dependent restraints, wheel locks, trailer stands, and wheel chocks.

5. The dock control system of claim 1 wherein the controller is configured to enable actuation of a door of the docking station upon receiving verification that a vehicle has been restrained.

6. The dock control system of claim 5 wherein the controller is configured to enable a leveler of the docking station once actuation of the door of the docking station is complete.

7. A method of operating a docking station of a distribution center, the method comprising:
engaging a docking restraint system to restrain a vehicle at the docking station;
activating a camera to obtain at least one image of the vehicle;
displaying the at least one image on a graphical user interface;
verifying if the vehicle has been restrained based on the at least one image of the vehicle; and
selectively enabling control of a door of the docking station based on whether restraint of the vehicle has been verified.

8. The method of claim 7 further comprising restricting control of the door of the docking station if restraint of the vehicle has not been verified.

9. The method of claim 7 further comprising enabling control of the door of the docking station upon verification that the vehicle has been restrained.

10. The method of claim 9 further comprising:
actuating the door of the docking station upon verification that the vehicle has been restrained;
enabling a leveler of the docking station upon complete actuation of the door of the docking station; and
operatively engaging the vehicle with the dock leveler.

11. The method of claim 7 further comprising displaying on the graphical user interface a request for verification that the vehicle has been restrained if a predetermined amount of time has passed since displaying the at least one image on the graphical user interface without verification that the vehicle has been restrained.

12. The method of claim 7 further comprising actuating the door of the docking station using the graphical user interface after verifying restraint of the vehicle.

13. The method of claim 7 wherein engaging a docking restraint system with the vehicle comprises engaging a rear impact guard (RIG) dependent restraint, a wheel lock, a trailer stand, a wheel chock, or a combination thereof.

14. A method of operating a docking station of a distribution center comprising the steps of:
receiving a trailer at a docking station of a distribution center;
engaging a trailer restraint system to secure the trailer against removal from the docking station;
upon trailer restraint system engagement, automatically activating a restraint verification system configured to require a restraint verification indication prior to permitting access to the trailer;
displaying an image of a trailer restraint from the trailer restraint system for user review;
sending the restraint verification indication upon user approval of the image of the trailer restraint; and
upon receiving the restraint verification indication, activating an automated trailer access system.

15. The method of claim 14 further comprising actuating a component of the docking station using a graphical user interface of the restraint verification system after activating the automated trailer access system.

16. The method of claim 14 wherein engaging a trailer restraint system to secure the trailer comprises engaging a restraint from one or more of the following categories: rear impact guard (RIG) dependent restraints, wheel locks, trailer stands, and wheel chocks.

17. The method of claim 14 wherein the automated trailer access system is configured to activate a remote control door system upon receiving the restraint verification indication.

18. The method of claim 17 further comprising automatically actuating the remote control door system in response to a remote activation signal to provide access to the trailer from the distribution center.

19. The method of claim 18 further comprising detecting actuation of the remote control door system and remotely activating a dock leveler system in response thereto.

20. A distribution center workflow verification system comprising:
a distribution center having a dock for exchanging materials with a mobile carrier engaged with the dock;
a mobile carrier restraint configured to secure the mobile carrier against removal from the dock;
a visual confirmation system including:
a camera configured to gather at least one image of the mobile carrier restraint, the at least one image comprising at least one video, at least one still image, or a combination thereof; and
a display configured to display the at least one image to a dock personnel member for confirmation of automatic engagement of the mobile carrier restraint;

a computer system configured to:
receive the at least one image of the mobile carrier restraint from the camera to determine engagement of the mobile carrier with the dock and an operational state of the mobile carrier restraint;
automatically engage the mobile carrier restraint upon detecting an engagement of the mobile carrier with the dock; and
restrict access to the mobile carrier until a signal indicative of visual verification of carrier restraint is received.

21. The system of claim 20 further comprising a sensor disposed within the distribution center and configured to provide operational feedback from the mobile carrier restraint; and
wherein the computer system is configured to receive the operational feedback from the sensor to determine engagement of the mobile carrier with the dock and an operational state of the mobile carrier restraint.

22. The system of claim 20 wherein the computer system is further configured to store the at least one image as a record of visual verification in response to the signal indicative of visual verification.

23. The system of claim 20 wherein the display of the visual confirmation system comprises a graphical user interface; and
wherein the computer system is configured to:
prompt an operator to verify carrier restraint on the graphical user interface; and
after carrier restraint has been verified, allow an operato
