Definitions

  • This invention relates broadly to devices for helping to prevent vehicular barrier gate arms from lowering in certain situations (such as if an obstruction such as a person is present), while not impacting the primary operation and function of the barrier arm (which is to lower the arm to prevent unauthorized vehicles from entering/exiting an area).
  • Vehicular barrier gate operators are designed as traffic control mechanisms to restrict vehicular entry or exit from a designated area (such as a parking area).
  • the "default" position of the barrier arm or arms typically is in the lowered (or down) position, at least during hours in which the access is being controlled.
  • the arm(s) raise only when a vehicle has been granted entry or exit permission. Commonly, this permission is automated (via proximity cards or other technology). Following such authorization, once the barrier arm has raised and the vehicle passes through, typically the arm rotates or otherwise moves back to the "default" down position (again, to maintain the desired control of the designated area).
  • That prior art approach to the risk is less than ideal.
  • it can provide an opportunity for drivers of unauthorized vehicles to "beat" the gate by closely following behind an authorized vehicle - as the arm begins to descend after the authorized vehicle has entered the controlled area, the unauthorized vehicle interrupts the photo-beam and/or sets off the sensor just as a person/pedestrian does, which (like the pedestrian's interruption/triggering of the sensor) then prevents the arm from rotating down (or even reverses the downward movement).
  • the control arm stopped and/or raised again, the unauthorized vehicle can then enter/exit the controlled area, thus defeating the primary purpose of the gate/arm control system - to stop unauthorized vehicular traffic through the gate.
  • FIG. 1 is a perspective view of an exemplary controlled gate/arm installation, in which an arm 1 allows an authorized vehicle 2 to enter (or exit, depending on the
  • FIG. 2A is one of the many embodiments of a controlled access gate constructed in accordance with the current invention. The view and most elements are similar to those in FIG. 1 , but among other things, FIG. 2A illustrates how an unauthorized vehicle 3 will NOT stop or reverse the downward motion of arm 1 - instead the arm motion 5 continues downward despite the exit attempt by the unauthorized vehicle 3.
  • FIG. 2B is virtually the same as FIG. 2A, but illustrates how a pedestrian will cause the arm motion 6 to occur (very similarly to the arm motion 4 of FIG. 1).
  • FIG. 3 is a prior art drawing illustrating one of the types of vehicle sensors (an induction loop) that may be utilized as part of the present invention.
  • a photo-beam system or other sensor is used to detect non- vehicular obstructions (such as persons) beneath the barrier arm, and absent some other signal (such as described below), that sensor will function in much the same manner as in the prior art systems discussed herein (interruption of the photo- beam will cause the arm 1 to reverse its downward motion, as shown by arrow 6 in FIG. 2B.
  • an additional sensing means is provided (such as a vehicular inductance loop system such as shown in FIG. 3, which is preferably located operably generally under the unauthorized vehicle 3's position in FIG. 2A) to detect the presence of a vehicle beneath the barrier arm.
  • this additional sensing means can take any of a range of forms and technologies, but preferably functions to distinguish whether the interruption of the photo-beam has been caused by (a) a vehicle or (b) a person or persons (or even more broadly, something OTHER than a vehicle). If the latter (a person, something OTHER than a vehicle, etc.), the embodiment preferably does stop or reverse the motion of the arm 1 , as described above, helping to ensure that the person is not struck by the descending arm 1.
  • the embodiment preferably does NOT stop or reverse the motion of the arm 1 (see illustrative arrow 5 showing this continuing downward arm motion), and instead the arm 1 continues its downward motion into the default closed position, so that the integrity of the "controlled area" is maintained.
  • ... a continuous run of wire that enters and exits from the same point.
  • the two ends of the loop wire are connected to the loop extension cable, which in turn connects to the vehicle detector.
  • the detector powers the loop causing a magnetic field in the loop area.
  • the loop resonates at a constant frequency that the detector monitors.
  • a base frequency is established when there is no vehicle over the loop.
  • the resonate frequency increases. This increase in frequency is sensed and, depending on the design of the detector, forces a normally open relay to close.
  • the relay will remain closed until the vehicle leaves the loop and the frequency returns to the base level.
  • the relay can trigger any number of devices such as an audio intercom system, a gate, a traffic light, etc.”
  • some automated signal processing and logic such as a computer program/logic (code) is provided to receive the sensor input(s) and make the determination as to whether the photo-beam interruption is being caused by a vehicular or non- vehicular obstruction, and to thereafter (relatively immediately) cause the barrier arm system (and specifically arm 1) to move (and/or stop) in an appropriate manner.
  • the system prevents the arm 1 from rotating down if a non- vehicular obstruction is present, but allows the barrier arm 1 to rotate down if a vehicle is present.
  • the system differentiates between (a) a non-vehicle interrupting the photo-beam (and thereafter prevents the arm 1 from further rotating down) and (b) a vehicle interrupting the photo-beam (in which case the system preferably allows the arm 1 to continue to rotate or otherwise move down to a default closed position).
  • the system of the invention thus provides a means to help prevent accidents to pedestrians who inadvertently (or intentionally) find themselves in a controlled access traffic lane.
  • the computer logic also can monitor for the presence of, and correct operation of, the photo-beam system/inductive loop system, on each cycle of the barrier arm 1 (each time the arm 1 operates to "open” and allow an authorized entrance or exit). If such monitoring indicates that the photo-beam system and/or the inductive loop system are not connected to the barrier arm operator and/or are not otherwise operating correctly, the system can be set to "deactivate” any motion by the barrier arm 1 , or to operate in some other "safe” manner.
  • the system can be programmed so that, if an electric fault exists in the photo-beam system and/or the inductive loop system, the barrier arm operator will not be allowed to rotate the barrier arm 1 to the down position.

Abstract

L'invention concerne des procédés et des appareils qui permettent d'empêcher la descente de bras de barrières bloquant le passage de véhicules dans certaines situations (par exemple si une obstruction telle qu'une personne est présente), sans compromettre l'utilisation et la fonction principale du bras de barrière (à savoir l'abaissement du bras pour empêcher que des véhicules non autorisés ne pénètrent dans une zone/quittent une zone).
