Abstract

An uninterruptible power source (UPS) for supplying power to a barrier operator when mains power has failed is disclosed. The UPS includes a UPS controller for detecting and responding to a mains power failure and capable of generating a plurality of control signals. A backup power source and an up-converter is connected to the UPS controller, wherein the up-converter increases the voltage of the backup power source when needed. A switch is responsive to one of the plurality of control signals of the UPS controller and toggles the operator barrier between the up-converter and the mains power source, and awakens the operator via a standby receiver power line. Another embodiment awakens the operator anytime a UPS receiver receives a preamble of a wireless transmission signal. Auxiliary lighting may also be associated with the UPS and/or photo-electric safety devices.

3. The uninterruptible power source as recited in claim 2, wherein the battery is of a re-chargeable type selected from the group consisting of lead-acid, lithium-ion, nickel metal hydride, nickel cadmium, sodium/sulfur, nickel/sodium, manganese-titanium, rechargeable alkaline manganese, nickel zinc, iron-nickel, iron silver, redox (liquid electrode), lithium-sulfur and supercapacitors.

4. The uninterruptible power source as recited in claim 2, further comprising:

a battery monitor connected to said battery, wherein said monitor indicates the status of the battery to a user.

5. The uninterruptible power source as recited in claim 4, further comprising a battery heater connected to said UPS controller and positioned proximal said battery.

6. The uninterruptible power source as recited in claim 1, wherein said UPS controller supplies continuous standby power to the barrier operator via a standby receiver power line.

7. The uninterruptible power source as recited in claim 1, further comprising:

auxiliary lights connected to the barrier operator and controlled by one of said control signals.

8. An access barrier movement apparatus for moving an access barrier when mains power has failed, the apparatus comprising:

a barrier operator having an operator receiver responsive to communication signals and an operator power converter for converting mains power to DC power;

an uninterruptible power source connected to said barrier operator and comprising;

a UPS controller responsive to failure of the mains power, said UPS controller sending and receiving a plurality of signals to control the operation of said access barrier operator;

a backup power source connected to said UPS controller, said UPS controller providing said operator receiver with continuous operating power;

a standby receiver power line coupled between said barrier operator and said UPS controller, said standby receiver power line continuously supplying standby power from said backup power source to said operator receiver;

an up-converter connected to said UPS controller and said backup power source, said up-converter increasing the voltage of said backup power source in response to signals from said UPS controller; and

a switch connected to said UPS controller, said switch controlled by said UPS controller, wherein said switch toggles said barrier operator between the mains power source and said up-converter in response to said UPS controller.

9. The access barrier movement apparatus as recited in claim 8, wherein said backup power source comprises a battery.

10. The access barrier movement apparatus as recited in claim 9, wherein said battery is of a re-chargeable type selected from the group consisting of lead-acid, lithium-ion, nickel metal hydride, nickel cadmium, sodium/sulfur, nickel/sodium, manganese-titanium, rechargeable alkaline manganese, nickel zinc, iron-nickel, iron silver, redox (liquid electrode), lithium-sulfur and supercapacitors.
