Three questions: the basic introduction of a gate, the working principle of the two gates, the application range of the three gates
Basic introduction to the gate
The earliest application of gates in China was used in subway projects during the 1980s. As the main equipment of the "automatic ticket checking machine" in the "automatic ticket checking system AFC", the gate is also the earliest and most extensive understanding of the gates. In the late 1990s, gates gradually appeared in ordinary civilian and commercial occasions, including office buildings, supermarkets, scenic spots and even high-end residential areas.
It should be pointed out that the gate and the ticket gate are not identical concepts. The ticket checking machine includes an automatic ticket checking machine and a portable ticket checking machine. The automatic ticket checking machine is a specific application of the gate machine combined with the ticketing system. The range of gates is wider, as long as it is used for managers to flow in and can meet one pass only one device can be regarded as a generalized gate.
How the gate works
According to the different control methods of the movement, it is divided into mechanical, semi-automatic and fully automatic. Some manufacturers refer to semi-automatic as electric and automatic as automatic.
The mechanical type controls the movement of the blocking body (connected to the movement) by manual control, and the mechanical limit controls the movement of the movement;
Semi-automatic is to control the movement and stop of the movement by electromagnet;
Fully automatic is to control the movement and stop of the movement through the motor.
The opening and closing of the blocking body is further controlled by controlling the movement and stopping of the movement.
According to the number of movements and blocking bodies included in the same gate, the gate can be divided into a single movement (including one movement and one blocking body) and a double movement (including two movements and two blocking bodies). , in a bilaterally symmetric form).
According to the different obstacles and blocking methods, it can be divided into three roller gates, swing gates, wing gates, translation gates, turn gates, and one-word gates.
Application range of gate
As a kind of channel management equipment, the most essential function of the gate is to pass only one person at a time by blocking and releasing. The application object is pedestrian (including carrying luggage and bicycles, etc.), the application is the entrance and exit, but as the intelligent channel management As part of the system, the gates can be used in conjunction with other systems for different special occasions to play a greater role.
At present, the most common systems for gates are access control systems and ticketing systems.
In the access control system, the earliest blocking method is the electric control door, but the door can not effectively realize only one person at a time, and due to the limitation of structure and form, the use occasion is limited; changing the gate can solve these problems, especially in buildings or The entrance and exit of the closed geographical area is very suitable for the use of 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 gate is even more inseparable. As long as it is a non-manual automatic ticket checking, the gate will not be opened. The most typical of the two application types are rail transit and e-tickets. Rail transit, including subways, high-speed rails, etc., no longer regards the gate as an independent product, but is part of the automatic ticket checking machine; electronic tickets mainly refer to the automatic check-in of entrances used in various places for paying for entertainment, including Scenic spots, playgrounds, stadiums, ski resorts, entertainment venues, etc.
