Why automatic doors can be opened and closed automatically
In front of many high-end commercial buildings or halls, a door can be opened and closed automatically. When a person walks towards it, the door will automatically open, and when someone enters, it will automatically close again. It's really amazing. How does it know that someone is going in? What force opened the door? In fact, the earliest automatic doors existed 3000 years ago, but they are much more complicated than they are now.
In today's scientific development, there are more and more types of automatic doors in Jiangsu, and the structure is becoming simpler. They feel the arrival and departure of people in different ways, and finally they open or close the door by the power of electricity.
Do you know any of the more common automatic doors?
There are three main ways of operating modern automatic doors:
① Pedal type:
There is a pressure switch under the pedal.
In this type of door, a carpet is placed in front of the door, and a wire is connected to the power supply under the carpet. When a person stands on the carpet, the weight of the carpet increases, so the power is turned on and the door is opened; after the person enters, the weight on the carpet is reduced, the power is cut off, and the door closes automatically after a few seconds.
② Photoelectric beam type:
Beam emitting device and photoelectric sensing device are installed near the door
This kind of door has a light beam near the door. When people pass, the light beam is interrupted, so the power is turned on, and the door is opened. After the person enters, the light beam continues to recover, and the power is cut off. It closes automatically.
③ Button method:
Press the switch-like button by hand to open the door leaf.
This type of door has a switch next to the door. When people put their hands on the switch and press the switch, the power is turned on and the door is opened. After a person enters, the power is cut off within a few seconds and the door closes automatically.
