Why are flap barrier gates commonly chosen for subway passage gates?

The subway is an essential public facility for many city residents to go out, making it convenient for pedestrians to travel. In addition, the subway is also a place with a particularly high flow of people. Due to high mobility, the number of personnel passing through is too complex. Therefore, this is also the place where hidden dangers are most likely to occur. Therefore, the subway cannot be managed solely by security personnel. At present, the most popular types of subway turnstile gates are tripod turnstiles, flap barrier gates, swing barrier gates, etc. But the most commonly used one is the flap barrier gate, why is that? 

Reasons for the widespread use of flap barrier gates in subway passage gates

1) Equipped with automatic problem detection and logical judgment functions, it is more convenient for users to debug the functions;

2) There are dozens of high-performance sensitive dialing setting devices available;

3) Mechanical and infrared have two layers of anti pinch performance. During the reset process, if the blocking arm is obstructed, it will automatically stop or rebound, and an alarm signal will be issued together;

4) Multiple forms of alarm functions, including illegal intrusion, reverse tracking, single use timeout alarm, etc;

5) Anti impact function: When no door opening signal is received, the blocking arm actively locks;

6) Reverse intrusion disable alarm function. After swiping the card forward, when someone enters from the opposite direction, the wings will quickly close and sound an alarm;

7) The sensitive traffic indication performance, high brightness indicator lights, and more user-friendly prompt functions make the channel more distinctive;

8) The normally open and normally closed forms are adjustable and can be easily controlled through dialing or external manual buttons;

9) Active detection and reset function. After opening the door, if no object is detected passing by within the specified time (adjustable), the system will actively cancel the permission for this passage;

In the event of a power outage, proactively turn it on to meet fire safety requirements;

It is precisely because of these functions of flap barrier gates that wing flap gates are widely used in subways.
