Automatic door control systems are designed to and doors without the need for human intervention. These systems are commonly used in commercial, industrial, and public buildings, such as shopping malls, airports, hospitals, and offices, where convenience, accessibility, and hygiene are important. The primary purpose of an automatic door system is to provide seamless and efficient and for users. Sensors detect the presence or approach of a person or object to trigger the opening of the door. Common types include motion sensors that use infrared or microwave technology to detect movement, pressure sensors embedded in mats to detect weight when a person steps on them, and proximity sensors that use radio frequency or ultrasonic waves to detect objects near the door.
The control system is the central unit that processes signals from the sensors and sends commands to the door operator to or the door. It can be programmed for different opening speeds, durations, and sensitivity levels. The door operator is the mechanism responsible for opening and closing the door. It typically includes an electric motor and an actuator that work together to move the door along a track or swing it open, depending on the door type. Safety sensors, such as infrared beams or laser scanners, are installed to detect obstructions in the door's path. If an obstruction is detected, the door will stop or reverse to prevent or .
Doors may require keycard swipes or keypad codes to grant access to authorized individuals, especially in secure areas like offices, warehouses, or data centers. High-security systems use fingerprint, facial recognition, or retina scanners to ensure only authorized personnel can . Some systems are controlled remotely, allowing security personnel to unlock doors via apps or control rooms. In public buildings or industrial settings, doors often include panic bars that allow for quick during emergencies. Furthermore, automatic doors can be programmed to when a fire alarm is triggered, allowing for rapid evacuation. Many automatic doors have backup power systems to ensure continued operation during a power, opening automatically to provide exit access.
