Induction doors, also known as automatic doors and intelligent doors, are doors that can be opened and closed automatically and play a very important role in people's access, traffic and safety, and can be widely used in public places such as shopping malls, hotels, airports, subways, hospitals and some family homes. It uses electromagnetic induction, infrared induction, acoustic induction and other principles to control the automatic opening and closing of the door.Quick Roll-up Door
A, the design principle of induction doors
The induction door uses modern electronic technology, mechanical design and the comprehensive use of material science:
Principle
The control system of the induction door is composed of three main parts: the controller, the execution parts and the inductor. The sensors detect changes in the surrounding environment, such as the movement of people or vehicles, and send signals to the controller, which then controls the opening and closing of the door through the actuators. The controller acts as the brain and centre of the control system, the actuator opens and closes the door and the sensor acts as a sensor.Quick Door
Sensors
The sensors are mainly infrared sensors, ultrasonic sensors, magnetic sensors and so on. Among them, infrared sensor is the most widely used one, its principle is based on the sensitivity of infrared electron tube to detect the presence of human body or object, and send the signal to the controller for processing. Ultrasonic sensors are based on acoustic principles to detect the presence of objects and humans, and are mainly used in garages and freight premises. Magnetic sensors use the magnetic field of people or metalwork to automatically open and close doors.Automatic Glass Door
The controller is the core component of the induction door. Its role is to analyse and process the signal from the inductor and then issue commands to control the execution components. The main components of the controller include the main chip, high voltage power supply, input and output interfaces, capacitors, resistors and various sensors. The level of design of the controller directly affects the effectiveness and performance of the opening and closing of the door, therefore its rationality, stability and safety are very important.
Actuating components
The main actuating components are motors, reducers and drive mechanisms, which control the opening and closing of the door by means of signals from the controller. These components need to have a strong load-bearing capacity, operational performance and ensure the smooth operation of the door.
Second, the characteristics of the induction door and the use of places
Features
①Automatic discovery: able to automatically sense the presence of people without human intervention, greatly improving ease of use and efficiency.
②Quick and convenient: automatic door opening speed is very fast, only a gentle push to complete the opening operation, very convenient and quick.
③Energy saving and environmental protection: the induction door can automatically close, avoiding long time open, greatly reducing energy loss, reducing the energy consumption of air conditioning, very beneficial to energy saving and environmental protection.
④Safe and reliable: the electronic control technology and mechanical design of the induction door ensure the safety and reliability of the door, preventing misuse and door jamming, avoiding unnecessary injuries to personnel.
Place of use
Induction doors are mainly used in public places such as shopping malls, hotels, airports, subways, hospitals and some family residences. It can achieve a variety of effects such as automatic control, fast access, safety and convenience. At the same time, the induction door can be set up in different functional modes according to different needs, such as normally open, normally closed, staggered, one-way passage, etc., which greatly improves the adaptability and usability of the door.
