History of Automatic Doors
Modern automatic doors emerged in the 19th century with mechanical innovations like the “fly fan door.” In the late 19th and early 20th centuries, inventors like Lewis B. Ketcham and Theophilus Van Kannel developed pneumatic-based door-opening systems.
The early 20th century brought further advancements to automatic doors. In 1921, Dee Horton and Lew Hewitt developed an electrically powered sliding door system called the “Horton Automatic Door.” This system used electric motors and gears to open and close the doors.
The introduction of radar and sensor technology in the mid-20th century revolutionized automatic doors. These advancements led to commercialization and widespread use in commercial buildings, public spaces, and transportation hubs.
Automatic doors have evolved into sliding, swinging, revolving, and folding types, incorporating advanced technologies such as motion sensors and touchless interfaces. They promote convenience, accessibility, and energy efficiency in modern architecture.
Introduction to Automatic Doors
Automatic doors are a type of door that opens and closes automatically, without requiring any physical effort from the person entering or exiting. They are very commonly used in many commercial, industrial, and residential setup settings to improve accessibility, convenience, and safety.
Automatic doors operate using a variety of mechanisms, including motion sensors, pressure sensors, and remote-control systems. When a person approaches the door, the sensors detect their presence and trigger the door to open automatically. Some automatic doors also have safety features, such as sensors that detect obstacles and prevent the door from closing on someone or something.
Automatic doors come in various styles, including sliding, swing, and revolving doors made of materials including glass, metal, and wood. They can be customized to suit the aesthetic and functional needs of a particular building or space.
What is an Automatic Door System?
An automatic door system is a type of door that can open and close automatically without physical contact. It typically uses sensors or other detection devices to sense the presence around or within its vicinity and then activates the opening and closing mechanism accordingly. Automatic Doors Toronto comes in various types, including sliding, swinging, and revolving doors powered by electric motors, and hydraulic, or pneumatic systems.
Mechanism of Automatic Doors
Automatic doors utilize motion sensors, optical sensors, pressure mats, radar systems, push buttons, and safety and control systems. These mechanisms detect movement, interruptions in infrared or laser beams, pressure, or obstructions and send signals to initiate the opening or closing of the doors. The specific mechanisms depend on the door type, such as sliding, swinging, revolving, or folding doors.
Most automatic doors utilize microwave pulse sensors or passive infrared (PIR) sensors. Microwave pulse sensors emit microwaves in the surrounding area and measure the reflections of these microwaves. When a person or object moves within the sensor’s range, it causes a change in the reflected microwaves, signaling the presence of motion and initiating the door’s opening or closing.
The passive infrared (PIR) sensors detect any changes that may occur in the infrared radiation field of view. When a person or entity moves, it generates a temperature difference detected by the PIR sensor, triggering the door’s operation.
How do Automatic Doors Work?
Automatic doors typically work by using sensors or detectors to detect the presence of a person or object in the doorway and then activating the door to open and close automatically. When the sensor senses a presence, it sends a signal to the door operating mechanism. After receiving that signal, the mechanism opens the door.
There are various types of automatic door sensors that are commonly used to detect the presence of people or objects and activate the door to open and close automatically. But let us tell the three most frequently used three types of automatic door sensors:
- Pressure Sensors: Pressure sensors are commonly used in automatic sliding doors. They are placed on the floor mat before the door and detect when someone steps on it. When pressure is detected, the door opens automatically. Pressure sensors are ideal for use in areas with a lot of foot traffic, and the door needs to open and close frequently.
- Motion Detection and Optical Sensors: Motion detection and optical sensors are commonly used in automatic swinging doors. These sensors use a combination of infrared, microwave, or optical technology to detect motion in the doorway. When someone approaches the door, the sensors detect their movement and activate the door to open. These sensors are ideal for use in areas with less foot traffic, such as offices or conference rooms.
- Access Control or Video Intercom System: An access control or video intercom system is commonly used in automatic revolving doors. The system requires the user to present a key card and a code or use a video intercom to access the door. Once access is granted, the door will begin to rotate automatically. These systems are ideal for high-security areas like government buildings or financial institutions.
