Abstract

An operator system and related methods for automatically controlling access barriers which includes a base controller associated with at least one access barrier and at least one base receiver associated with the base controller. The system also includes at least one mobile transmitter that automatically and periodically generates at least one mobile signal detectable by the base receiver. The base controller selectively generates barrier movement commands upon receipt of the at least one mobile signal. Timers may be used to block receipt of any mobile signals for a period of time to prevent any further door movement. Such a system allows for hands-free operation of the access barrier. A discrete processing system may also be used to retrofit existing barrier operator systems for use in hands-free operation.

Claims

1. A discrete-add on processing system adapted to be connected to a barrier operating system which moves a barrier between open and closed positions, the processing system comprising:

at least one mobile transmitter automatically and periodically generating at least one mobile signal;

a barrier position indicator generating a barrier position signal; and

an add-on controller adapted to be connected to the barrier operating system, said add-on controller receiving said at least one mobile signal and said barrier position signal so as to enable the barrier operating system to move the barrier based upon whether the at least one mobile signal is received or not.

2. The processing system according to claim 1, further comprising:

a receiver connected to one of said add-on controller and the barrier operating system, the receiver receiving said at least one mobile signal.

3. The processing system according to claim 1, wherein said add-on controller stores said mobile signal for later processing.

4. The processing system according to claim 3, wherein said mobile transmitter periodically generates a first identification signal and a second identification signal which, if received by said add-on controller, are stored in corresponding buffers.

5. The processing system according to claim 4, wherein said add-on controller initiates a change in the barrier operating system based upon said condition signal and said at least one mobile signal.

6. The processing system according to claim 5, wherein said at least one position indicator comprises:

a magnet adapted to be proximally secured to one of a trailing and a leading edge of the door in the barrier operating system; and

a pair of inductive switches adapted to be maintained in a track which guides the door, wherein each said inductive switch detects a presence of said magnet and generates said barrier position signal received by said add-on controller.

7. The processing system according to claim 6, whereupon detection of a change in the position of the door, said add-on controller initiates a timer having a corresponding time period, wherein said add-on controller ignores receipt of said mobile signals for said corresponding time period.

8. The processing system according to claim 1, wherein said at least one mobile transmitter comprises an activity sensor, wherein said at least one mobile signal is only generated if said activity sensor detects a predetermined activity.
