Abstract

An access control barrier of the type used for vehicle access, livestock and crowd control, a drive mechanism for a barrier and a control system therefor is disclosed. The barrier comprises a boom arm mounted for rotation with respect to a support post, the boom arm being movable between a closed blocking position and an open access position in response to a signal in which the boom arm comprises a first arm element, rotatably driven at one end around a horizontal pivot axis mounted on said support post, and a second arm element pivotally coupled to the other end of the first arm and driven to rotate with respect thereto during the transition between said open and closed positions. A drive mechanism for the barrier is adapted to move the boom arm between its open and closed positions about its horizontally disposed pivot axis is described. A control system governing electronic actuation of an access control barrier utilising remote means, barrier movement control, remote monitoring features, the powering of said barrier and the detection of interference with the barrier and deterrent means to prevent or minimise further interference is also defined.

Abstract

A control system for an access barrier of the type used for vehicle access, livestock and crowd control, a drive mechanism for a barrier and a specific arrangement of barrier is disclosed. The control system comprises a series of conductors through which interference of the barrier is detected. The nature of the interference is assessed and a deterrent delivery mean provides warnings against continued interference. Triggered responses increase if the interference persists and deterrents, selected from audio, visual or electric shock, are produced by the control system. The deterrents are regulated in amplitude, frequency and duration of timed pulses. A drive mechanism for the barrier is adapted to move the boom arm between its open and closed positions about its horizontally disposed pivot axis is disclosed. A control system governing electronic actuation of an access control barrier utilising remote means, barrier movement control, remote monitoring features, the powering of said barrier and the detection of interference with the barrier and deterrent means to prevent or minimise further interference is also defined.
