Working principle and classification of speed door
Speed gate is initially used by traditional doors to prevent outsiders from going in and out. Later, it develops into electromagnetic doors and scissors doors, which enable them to get in and out more efficiently through authorization. To the present swing door, it is more safe and convenient. Let's look at the working principle and classification of the speed gate.
Working principle of speed door
The speed gate door is driven by the control system, automatically opens and closes. It can be programmed by setting up the operation mode: as long as the entrant is authorized, the door opens automatically. After the delay is closed, the time delay can be adjusted.
Classification of speed door
The common speed door is divided into two kinds of door (wing gate) and swing door according to the different movement mode of the door wing.
Shear doors are often used in rail transit, and most of the common shear doors appear in subway and other places. The wing of the door is extended from the inside of the box, which can effectively seal the channel and play the role of control. In addition, the interior of the door is equipped with infrared sensing device, which can achieve the goal of one person and one card: a single pass.
The swing door is more late than the shear door, which belongs to the second generation speed door. The characteristic of this kind of fast pass is that the direction of the door wing is running before and after. The operation process is within the sight of the human body, and it is more safe. In addition, the style of the swing door is more changeable because the wing of the door does not have to be trapped inside the box. Due to the above features, swinging doors are generally used in banks, enterprise buildings, high grade office buildings and so on.
