Patent ID: 8730063

Claim:
A vehicle barrier security system for controlling a barrier at a security checkpoint comprising: a power source providing power; a CLOSE switch connected to the power source and configured to provide power from the power source to raise the barrier when the CLOSE switch is activated; a vehicle detection relay configured to receive the power from the CLOSE switch at a first contact of the vehicle detection relay and provide the power to a second contact of the vehicle detection relay when a vehicle is not detected at the checkpoint; an actuation relay comprising an actuation relay coil, the actuation relay configured to receive the power from the second contact of the vehicle detection relay thereby energizing the actuation relay coil and providing the power from a first contact of the actuation relay to a second contact of the actuation relay; a latching relay connected in series with the second contact of the actuation relay and configurable to be in a latched state or a reset state, wherein the latching relay is configured to receive the power from the second contact of the actuation relay at a first contact of the latching relay and provide the power from the first contact of the latching relay to a second contact of the latching relay when the latching relay is in the reset state; an actuation mechanism electrically connected to the second contact of the latching relay and configured to raise the barrier when: the actuation relay provides the power to the second contact of the actuation relay, when the latching relay is in the reset state, and when the power is provided from the first contact of the latching relay to the second contact of the latching relay thereby providing power to the actuation mechanism; and an automatic reset relay configured to receive power at a first contact of the automatic reset relay and provide power to a second contact of the automatic reset relay when energized, thereby providing power to a reset coil of the latching relay and resetting the latching relay.
