How do anti-tailing pedestrian channel turnstile barrier gates achieve anti-tailing problems?
When the pedestrian passes the pedestrian passage, the person in front legally swipes the card, the gate opens the door, the card reader enters legally, and the person behind does not swipe the card to enter with the person in front. This is the trailing phenomenon. Some people deliberately followed, and some people accidentally followed. For example, when the card is swiped, the gate does not read the information, and the cardholder goes along with it, which is unintentional trailing. Regardless of whether it is intentional or not, users who install the pedestrian channel gates do not want to have a trailing phenomenon, or they lose the meaning of existence, and they hope that the gates can be prevented from trailing. In fact, it is very difficult to prevent the tailing of the gate. For example, let's analyze it from several common models of pedestrian passage gates.
The three-roller brake has the best anti-tailing effect. When each person passes the gate, the brake lever rotates once. The space between the two brake bars is limited, and it is not possible to crowd many people, at least to prevent unintentional followers. However, intentional followers can still use this space to squeeze in.
The wing gate's anti-tailing ability is worse. When two people enter the gate together closely before and after, the gate operator mistakenly believes that this is a person. The principle of judging the number of gates is based on whether there is a gap between people.
The anti-tailing ability of the swing gate is even worse, the swing arm speed is slow, and it can be squeezed in before closing the door. Of course, it is also possible to deceive the gates by using two people to closely arrange them.
The swing gate and wing gate should be designed to be truly anti-tailing. It is designed to be a "two-door". First enter the first door and judge the rear gate to open the second door. Of course, such a design, the cost of the pedestrian passage gate will be greatly improved. Generally, airports and customs use more gates for such two doors.
The anti-tailing of the gate is a social problem and a management issue. It is very difficult to solve the anti-tailing gate alone. To solve the trailing problem, there is also a way to reduce the efficiency. That is to set the yellow line area and open the distance between the current card reader and the latter.
