                              How does the turnstile work and which fields are used?


The earliest application of turnstiles gate  in China was in subway projects during the 1980s. As the main equipment of the "automatic ticket gate" in the "Automatic Fare Collection System AFC", the turnstile gate is also the earliest and most extensive understanding of gates by the Chinese people. In the late 1990s, flap turnstiles  gradually appeared in ordinary civilian and commercial occasions, including office buildings, shopping malls, supermarkets, scenic spots and even high-end communities.

It should be pointed out that flap barrier gates and ticket gates are not exactly the same concept. Ticket checking machines include automatic ticket checking machines and portable ticket checking machines. The automatic ticket checking machine is a specific application of turnstiles combined with ticketing systems. The scope of turnstiles is broader, as long as it is used to manage the inflow and outflow of people and can meet the requirements of only one person at a time, it can be regarded as a generalized turnstile.


The working principle of flap barrier turnstile

According to the different control methods of the movement, it is divided into mechanical, semi-automatic, and fully automatic. Some manufacturers will call the semi-automatic type an electric type, and the fully automatic type as an automatic type.


The mechanical type is to control the operation of the blocking body (connected to the movement) by manpower, and the mechanical limit controls the stop of the movement;


The semi-automatic type uses electromagnets to control the movement and stop of the movement;


The automatic type is to control the movement and stop of the movement through the motor.


By controlling the movement and stopping of the movement, the opening and closing of the blocking body is further controlled.


According to the difference in the number of movement and arresting bodies contained in the same gate, the gate can be divided into single movement (including 1 movement and 1 arresting body) and double movement (including 2 movement and 2 arresting bodies) , In a symmetrical form).


According to the difference of the blocking body and the blocking method, it can be divided into three roller gates, swing gates, wing gates, translation gates, turn gates, straight gates, etc.


Application range of turnstile


As a kind of channel management equipment, the most essential function of turnstiles is to realize only one person at a time through blocking and releasing. Its application objects are pedestrians (including luggage and bicycles, etc.), and the application occasions are entrances and exits, but as intelligent channel management As part of the system, the turnstile can be used in different special occasions with other systems to play a greater role.


At present, the most common systems supporting turnstiles are the access control system and the ticketing system.


In the access control system, the earliest blocking method is the electronically controlled door, but the door cannot effectively realize that only one person can pass at a time, and due to the limitation of the structure and form, the use occasions are relatively limited; switching to the gate can solve these problems, especially in buildings or Enclosed entrances and exits in geographical areas is very suitable for using turnstiles as the blocking mechanism of the access control system. Such as smart buildings, government agencies, corporate parks, communities, factories, prisons, etc.


The relationship between the ticket checking part of the ticketing system and the gate is even more inseparable. As long as it is a non-manual automatic ticket checking, it is inseparable from the gate. The two most typical application types are rail transit and e-tickets. Rail transit includes subways, high-speed rails, etc. The gates are no longer regarded as an independent product, but are classified as part of the automatic ticket gate; electronic tickets mainly refer to the automatic ticket gates used in various paid visits and entertainment occasions, including Scenic spots, playgrounds, gymnasiums, ski resorts, entertainment venues, etc.
