Infrared beams are widely used inaccess control optical turnstile gates, 3-4 pairs are used in general wing gates, flap barrier gateand swingturnstile, and 6-12pairs are used in speed-pass gates.Pedestrian turnstile gatethat requires a relatively high point will increase the logarithm of the infrared accordingly, increase the sensitivity of thelane, increase the anti-pinch performance of the gate, and strengthen the anti-tailing effect of thegate.

Infrared anti-radiation is composed of two parts: the transmitting end and the receiving end. As an important part of the gate system, itsrole cannot be ignored. It can be said that without infraredbeams, the judgment of the passage logic of the gate cannot be completed.

After the object blocks the infrared, the receiving end feeds back the blocked signal to the gateaccesscontrol board. The pass logic in the gate control boardwill decide whichtheoperation shouldbe performedsuch asclosing, opening, alarming or others by tellingthe passing state according to the position and quantity of the infrared blocked.

Thefunctionof infraredsensorsin the gate is equivalent to the human eye. Theaccess controlmain board of the gate is similar to the human brain, and the "eyes"feed back what it saw to the brain, and the brain will decide how to act.
