The Function of Infrared Sensor Detection in the Pedestrian Access Gate
The #safety performance of the #pedestriangate #turnstiles products is an important indicator to measure the products. The mechanisms of the pedestrian gate products in terms of pedestrian movement track and behavior identification detection, anti-pinch mechanism for illegal pedestrians, emergency response handling in emergency situations, etc. are the basis to ensure the high safety of such #accesscontrol gate products.
? A certain number of through beam infrared detection photo #sensors will be set in the turnstile gate product. When pedestrians pass through the equipment, their bodies will block the detection #infraredbeams, so as to form an effective and rapid identification of the movement track and behavior of pedestrians. The high-density infrared detection #lightcurtain can also be used to judge the location area, status, direction of passage and the effectiveness of authorization verification of pedestrians in the gate #speedlane.
? The general functions of sensors at the pedestrian gate can be summarized as safety and security
?High level safety precautions

??The more sensors, the better the security and functionality will realize, but the higher the complexity of the logic algorithm. ?Among similar products, high-end manufacturers use up to 16 pairs, and some even use up to 20 pairs.
The anti-pinch protection function of the product is realized through the gate unit and the access detection system. When any protection sensor is triggered during pedestrian traffic, the gate lane will be open. When the door leaf of the passage is closed and is blocked by objects, the door leaf will immediately become free, so as to prevent people from being hurt and protect our pedestrians when passing.
Emergency handling functions in case of emergency. The fire signal shall be reserved for the pedestrian passage equipment. When receiving the fire signal warning or power failure, the door leaf will automatically release the lock and become free, forming an emergency evacuation crowd in the barrier free passage. It will not lead to accidental casualties. This emergency function can also realize the setting and switching of channel operation status through the remote channel monitoring and management system.?
Orderly Security and Management
It mainly refers to the detection, prevention and alarm mechanism of the pedestrian gate products for illegal personnel to prevent the occurrence of tailgating. The tailgate detection function includes two detection methods, one is tailgate entry detection, and the other is reverse entry detection.
The tailgating behavior in the tailgating detection function refers to the deceptive behavior that a person attempts to pass without passing the legal authorization. When an authorized person passes through the gate lane and has left the safe area of the lane, the pedestrian door leaf will automatically close. However, when an unauthorized person attempts to tailgate through the lane, the door leaf will block the passage of pedestrians. At this time, the gate will give an audible alarm and an indicator light alarm; When the authorized personnel are passing through the channel and have not left the safe area of the gate lane meanwhile the tailgating personnel try to follow them into the channel, the turnstile gate will have audible alarm and indicator light alarm to remind our staff of abnormal conditions while not close directly to reflects the security protection ability and personal safety protection ability of the pedestrian gate.
