Abstract

An operator system and related methods for automatically controlling access barriers including a controller associated with at least one access barrier and a transceiver associated with the controller for transmitting and receiving operational signals. The system also includes at least one proximity device capable of communicating operational signals with the transceiver based upon a position of the proximity device with respect to the barrier and/or the operational status of a vehicle carrying the proximity device, wherein the controller monitors the operational signals and controls the position of the access barrier based upon the operation signals. Such a system allows for hands-free operation of the access barrier.

Claims

1. An operator system for automatically controlling access barriers, comprising:

a base controller associated with at least one access barrier;

at least one base transceiver associated with said base controller; and

at least one remote transmitter periodically generating query signals, said at least one base transceiver in response to said query signals generating acknowledgment signals which are received by said at least one remote transmitter which subsequently generates movement commands to said base controller based upon receipt of a predetermined number of said acknowledgment signals.

2. The system according to claim 1, wherein said at least one remote transmitter generates at least two different power level query signals, wherein one of said different power level signals is used to generate a first direction movement command and the other of said different power level signals is used to generate a second direction movement command.

3. The system according to claim 2, wherein said at least one remote transmitter comprises:

a processor;

a transponder connected to said processor, said transponder generating said query signals and receiving said acknowledgment signals; and

a first button connected to said processor which when actuated cancels said movement commands.

4. The system according to claim 3, wherein said at least one transmitter further comprises:

a second button connected to said processor which when actuated initiates said movement commands.

6. The system according to claim 4, wherein actuation of said first button for a predetermined period of time selects specific power levels associated with said direction movement commands.

7. The system according to claim 6, wherein said remote transmitter has four different power levels to select from.

8. The system according to claim 4, wherein actuation of said second button for a predetermined period of time enables learning of said remote transmitter to said base controller.

9. The system according to claim 3, wherein said processor maintains a plurality of count variables wherein at least one of said count variables is used to count receipt of said acknowledgment signals and upon reaching appropriate values generating said movement commands.

10. The system according to claim 9, wherein said processor maintains a Current State variable which is adjusted according to said plurality of count variables.

11. The system according to claim 10, wherein said Current State is set to one of the following:

aLeam State, Vehicle Docked, Vehicle Leaving, Vehicle Away, Vehicle Approaching, Close Door or Open Door.

12. The system according to claim 11, wherein said Vehicle Leaving state is associated with one of said power level signals and said Vehicle Approaching state is associated with a different one of said power level signals.

13. The system according to claim 3, wherein said at least one remote transmitter further comprises:

an activity sensor connected to said processor, said processor sending said query signals only when said activity sensor determines that a device carrying said remote transmitter is on.

14. The system according to claim 13, wherein said activity sensor comprises:

a vibration sensor that generates a vibration signal received by said processor indicating that the device is on.

15. The system according to claim 13, wherein said activity sensor comprises:

an electrical noise sensor that generates a noise signal received by said processor indicating that the device is on.

16. The system according to claim 13, wherein said activity sensor comprises:

an ignition sensor that detects an ignition signal which is sent to said processor indicating that the device is on.

17. The system according to claim 2, wherein said signals communicated between said base transceiver and said remote transmitter are within a range of frequencies which is separable into a plurality of channels, and wherein said base controller selects one of said channels.

18. The system according to claim 17, wherein each said channel has a bandwidth of about 0.5 MHZ and said range of frequencies is between about 902 MHZ to about 928 MHZ.

19. The system according to claim 2, wherein said signals communicated between said base transceiver and said remote transmitter are encrypted.
