What are the key points for purchasing pedestrian access gates?
The main difference of pedestrian access gates is that in addition to the difference in door leaf movement, different grades of products are quite different in material technology, motor drive and control system. Regarding product selection, we mainly consider the following methods:
1. Personnel safety: high security personnel access guarantee
The main purpose is to understand the mechanism of pedestrian access gate products in terms of personnel movement trajectory and behavior identification detection, anti-pinch mechanism for illegal entry personnel, emergency response and handling in emergency situations, etc. These aspects are also the basis for ensuring high safety of pedestrian access gate products . Pedestrian passage gates are equipped with a certain number of cross-firing detection points at different positions inside the passage. When people pass by, their limbs will block the detection points. Multiple detection points form an effective identification of the movement trajectory and behavior of passing people. High-end pedestrian passage products are generally Instead of using the traditional point-type infrared detection method, it uses light curtain technology to judge the location, status, direction of passage and validity of authorization verification of pedestrians in the passage, and perform calculations and analyzes to make a decision. judge accordingly. The current tracking traffic detection method protects the safety of pedestrians.
2. High-level security protection level
The greater the number of sensor points, the better the safety and functionality, but at the same time the higher the complexity of the logic algorithm. Among similar products, high-end manufacturers use at most 16 pairs, some even as high as 20 pairs, and the minimum monitoring distance can reach 12 cm, while most domestic low-end product manufacturers use about 10 pairs. The minimum product is only 4 pairs, and Jieshun Technology pedestrian gate has as many as 48 pairs of electric eyes. The anti-pinch protection function of the product is realized through the door unit and the passage detection system. During the passage of pedestrians, if any protection sensor is triggered, the passage will be in an open state. And when the passage door leaves are blocked by objects when they are closed, the door leaves will immediately become free, which prevents the passing personnel from being pinched and ensures the safety of our pedestrians. Emergency handling function in case of emergency. Pedestrian access equipment should reserve fire signals. When receiving fire alarm signals or power outages, the door leaf will automatically unlock and become free, forming a barrier-free channel for emergency evacuation of the crowd. Will not lead to accidental casualties. This emergency function can also realize the setting and switching of the channel operating status through the remote channel monitoring and management system.
3. Security
The main purpose is to understand the processing mechanism of pedestrian passage products for detection, prevention and alarm of illegal entry personnel, so as to prevent the occurrence of personnel tailing. The trailing detection function includes two detection methods, one is trailing entry detection, and the other is reverse entry detection.
The tailgating behavior in the tailgating detection function refers to the deceitful behavior that people try to pass without legal authorization. When the authorized personnel pass through the passage, they have left the safe area of the passage. At this time, the passage door will automatically close, but at the same time If unauthorized personnel try to follow through the passage, the door leaf will block the passage of pedestrians. At this time, the passage will send out an audible alarm and an indicator light alarm; it will remind our staff of an abnormal situation. This situation reflects the security protection capability and protection of the pedestrian passage. Capability of personal safety.
