How do automatic doors work? Automatic doors have become an essential part of modern buildings, providing ease of access and enhancing the overall experience for both residential and commercial properties. But have you ever wondered how these doors work? In this blog post, we’ll explore the technology behind automatic doors, the different types available, and how they contribute to security, convenience, and energy efficiency.
The Basics of Automatic Doors
Automatic doors open and close without requiring manual effort, making them ideal for high-traffic areas or places where hands-free access is important. They work by detecting a person approaching the door and then activating a mechanism to open it. When the person passes through, the door closes automatically.
The technology behind these doors relies on sensors, motors, and control systems to ensure smooth operation. Here’s a closer look at how these systems come together to make automatic doors function:
Types of Sensors Used in Automatic Doors
-
Infrared Sensors: These are one of the most common sensors used in automatic doors. They emit infrared light, which bounces off objects in front of them. When a person or object enters the sensor’s field, the door is triggered to open. These sensors are especially useful for detecting movement in low-light conditions.
-
Motion Sensors: These sensors detect the movement of a person approaching the door. They typically use either microwave or infrared technology to detect motion. Microwave sensors emit microwave signals that bounce back when they hit an object, while infrared sensors detect changes in temperature or movement within their range.
-
Pressure Sensors: Found in the floor or threshold, pressure sensors detect the weight or pressure of a person standing nearby. Once the sensor registers the weight, it sends a signal to the door to open.
-
Radar Sensors: Radar sensors send out a radio wave that reflects off objects and people. If there is a movement within the sensor’s detection zone, the door is triggered to open.
How the Mechanism Works
When one of the sensors detects movement, it sends a signal to the door’s control system. The control system then activates the motor that powers the door. There are two main types of automatic door mechanisms:
-
Sliding Doors: These are the most common type of automatic doors, especially in supermarkets, malls, and offices. When triggered, the motor moves a set of sliding panels along tracks to open and close the door. These doors offer convenience and are space-efficient.
-
Swing Doors: Swing doors open like traditional doors but use automatic mechanisms to trigger the opening. The sensors send a signal to a motor, which opens the door. These doors are commonly used in hospitals and other healthcare facilities.
The Role of Control Systems
The control system is the brain of an automatic door, linking the sensors to the motor. It processes the signals received from the sensors and ensures the door operates smoothly. Control systems can be customised to suit specific needs, such as adjusting the speed of opening and closing, setting sensitivity levels for sensors, and providing timed operations.
Benefits of Automatic Doors
-
Convenience: Automatic doors offer effortless entry and exit, especially in high-traffic areas or for people with disabilities.
-
Energy Efficiency: Automatic doors can help reduce energy costs by minimising heat loss or gain. They open only when needed and close quickly, maintaining a comfortable indoor climate.
-
Safety and Security: Automatic doors can be equipped with safety features like sensors that detect objects in the door’s path, preventing injuries. They also enhance security by allowing access control mechanisms such as keycards or biometric systems.
-
Compliance with Accessibility Standards: Automatic doors make it easier for people with disabilities to enter and exit buildings, complying with accessibility regulations.
