Automatic door principle

Automatic door is a kind of door that can be opened and closed automatically. Its main principle is to use sensors to sense the existence of human bodies or objects, so as to automatically open or close doors. In general, automatic doors use infrared sensors or microwave radar sensors to control the opening and closing of doors by sensing the movement of human bodies or objects. The opening and closing mechanism of automatic door is usually composed of motor, reducer, transmission mechanism and controller, which can realize the smooth, fast and safe opening and closing of the door.

Application Scenes of Automatic Doors

Automatic doors are widely used in shopping malls, hospitals, airports, hotels, office buildings, schools and other public places, and are also adopted by more and more families. The application scenarios of automatic doors include but are not limited to the following aspects:

1. Convenience

The convenience of automatic door is one of its greatest advantages. The automatic door switch does not need manual operation, which can bring more convenient and quick access experience. Especially in crowded places, such as shopping malls and supermarkets, the use of automatic doors can effectively reduce crowded people and improve access efficiency.

2. Security

The switch mechanism of the automatic door is driven by electricity, which can ensure the smooth, fast and safe opening and closing of the door. At the same time, the sensor of the automatic door can sense the existence of human body or object in time, and avoid the collision and damage of the door caused by improper operation.

Step 3 save energy

Compared with the traditional manual door, the switch mechanism of automatic door is driven by electricity, which can save a lot of manpower and material resources. At the same time, the sensor of the automatic door can sense the existence of human body or object in time, which avoids the energy waste caused by opening the door for a long time.

Operation steps of automatic door

The operation steps of automatic doors are generally as follows:

1. Induction sensor

When a human body or an object approaches the automatic door, the induction sensor will automatically sense its existence.

2. Signal transmission

The inductive sensor transmits the sensed signal to the controller.

3. Controller processing

After receiving the signal, the controller will control the door opening and closing mechanism, so as to realize the automatic opening or closing of the door.

4. Door movement

After receiving the control signal, the door switch mechanism will start the motor and move the door body smoothly and quickly through the reducer and transmission mechanism.

5. End the operation

When a human body or an object leaves the sensing range of the automatic door, the automatic door will automatically close and the operation will end.
