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.

Claims

1. A loading dock remote control system comprising:

a facility having at least one docking station for exchanging materials;

a dock component configured to operate in at least two operational states;

an actuator configured to change the operational state of the dock component in response to an activation signal;

a mobile remote control configured to generate the activation signal to cause the actuator to change the operational state of the dock component;

at least one predefined non-activation zone wherein changing operational states of the dock component is inhibited when the mobile remote control is located within the at least one predefined non-activation zone; and

at least one activation zone wherein dock component operational state changes are permitted when the mobile remote control is within the activation zone;

wherein the non-activation zone is located within the activation zone to preclude dock component operational state changes when the mobile remote control is within a predefined proximity to the at least one docking station.

2. The system of claim 1 wherein the activation zone comprises a hot spot located within the non-activation zone.

3. The system of claim 1 wherein the activation zone extends about a periphery of the at least one docking station.

4. The system of claim 1 further comprising another non-activation zone surrounding the activation zone to preclude dock component operational state changes when the mobile remote control is outside a further predefined proximity to the at least one docking station.

5. The system of claim 1 wherein the non-activation zone is defined by at least one of an inductor coil monitored boundary, an infrared (IR) sensor monitored boundary, a radio frequency (RF) monitored boundary, a global positioning system (GPS) monitoring system, and a radar monitored boundary.

6. The system of claim 1 wherein the mobile remote control comprises at least one of personal digital assistant (PDA) and a portable computer.

7. The system of claim 1 wherein the mobile remote control is further configured to be mounted on a vehicle intended to facilitate exchanging materials.

8. The system of claim 7 wherein the vehicle includes one of a login and a pass-card and wherein the mobile remote control is further configured to generate an activation signal unique to the at least one of the login and the pass-card to actuate the actuator.

9. The system of claim 8 wherein the actuator is further configured to cause an operational state change of the dock component in response to only a particular activation signal corresponding to the at least one of the login and the pass-card.

10. The system of claim 8 further comprising an operator monitoring system configured to track movement of an operator through the facility by receiving and recording the unique activation signal generated by the mobile remote control.

11. The system of claim 1 further comprising a trailer position detector and wherein the actuator includes a lock out configured to only cause an operational state change of the dock component when the trailer position detector senses a trailer at a respective docking station.

12. A method of remotely controlling loading dock doors comprising:

receiving a trailer at a docking station having a remotely controllable dock component;

enabling remote activation of the remotely controllable dock component if an operator is located in a pre-designated activation zone; and

completely disabling remote activation of the remotely controllable dock component if the operator is located in a pre-designated non-activation zone, such that no change of an operational state of the remotely controllable dock component is permitted if an operator is located in the pre-designated non-activation zone;

wherein the pre-designated non-activation zone is located within the pre-designated activation zone to preclude dock component operational state changes when the mobile remote control is within a predefined proximity to the docking station.

13. The method of claim 12 further comprising logging in to a mobile remote control with at least one of a login, a password, and a pass-card, and wherein the mobile remote control is further configured to generate a remotely controllable dock component actuation signal that is unique to one of the login, the password, and the pass-card to actuate the remotely controllable doors.

14. The method of claim 13 further comprising only actuating the remotely controllable dock component in response to a particular unique remotely controllable dock component actuation signal corresponding to one of a particular login, password, and pass-card.

15. The method of claim 13 further comprising denying the logging in if the at least one of the login, password, and pass-card indicate an untrained status of the operator corresponding to the one of the login, password, and pass-card.

16. The method of claim 12 further comprising enabling at least one of remote leveling of the docking station and remote extension of an extendable conveyer system to the trailer received at the docking station upon actuation of the remotely controllable dock component.

17. A loading dock remote control system comprising:

a distribution center having a plurality of trailer positions, each trailer position having a dock thereat;

a dock component positioned at each dock and configured to be activated to permit and restrict access to and from the distribution center from the dock;

an actuator configured to actuate the dock component;

a receiver configured to cause the actuator to actuate the dock component in response to an activation signal;

a mobile remote control configured to generate the activation signal and transmit

the activation signal to the receiver;

at least one predefined non-activation zone in proximity to one of the trailer positions, wherein actuation of the dock component is disabled if the mobile remote control is located within the at least one non-activation zone; and

at least one activation zone wherein dock component operational state changes are permitted when the mobile remote control is within the activation zone;

wherein the at least one predefined non-activation zone is located within the activation zone to preclude dock component operational state changes when the mobile remote control is within a predefined proximity to the at least one docking station.

18. The system of claim 17 wherein the at least one non-activation zone encompasses a given proximity to a given dock to restrict actuation of the dock component when the mobile remote control is within the given proximity to the given dock.

19. The system of claim 17 wherein the mobile remote control is configured to wirelessly transmit the activation signal to the receiver.

20. The system of claim 17 wherein the dock component includes at least one of a trailer restraint, a leveler, and a dock door.
