How does the gate work and what fields are it used in?


   

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


It should be pointed out that gates and ticket gates are not exactly the same concept. Ticket gates include automatic ticket gates and portable ticket gates. Automatic ticket gates are a specific application of turnstiles combined with ticketing systems. The range of gates is wider, as long as it is used to manage the inflow and outflow of people and can satisfy only one person at a time, it can be regarded as a gate in a broad sense.


The working principle of the gate


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


The fully automatic type is controlled by the motor to run and stop the movement.


By controlling the operation and stop of the movement, the opening and closing of the blocking body are further controlled.


According to the difference in the number of movements and blocking bodies contained in the same gate, the gates can be divided into single movement (including 1 movement and 1 blocking body) and double movement (including 2 movements and 2 blocking bodies) , showing a left-right symmetrical shape).


According to the different blocking bodies and blocking methods, it can be divided into three roller gates, swing gates, wing gates, translation gates, turnstiles, one-way gates, etc.


Application range of gates


As a channel management device, the most essential function of the gate is to realize only one person at a time through blocking and releasing. Its application object is pedestrians (including carried luggage and bicycles, etc.), and the application is the entrance and exit, but as an intelligent channel management As part of the system, the gate can be used with other systems for different special occasions, so as to play a greater role.


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


In the access control system, the earliest blocking method is the electric control door, but the door cannot effectively realize that only one person can pass through at a time, and due to the limitation of structure and shape, the use occasions are relatively limited; switching to the gate can solve these problems, especially in buildings or Entrance and exit of a closed geographical area, it is very suitable to use the gate as the blocking mechanism of the access control system. Such as intelligent buildings, government agencies, enterprise parks, communities, factories, prisons, etc.


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