Introduction

Automatic door open and close systems have revolutionised the way we enter and exit buildings, providing convenience, efficiency, and improved accessibility. In this blog post, we will delve into the working principle of automatic door open and close systems, explore their main components, discuss how they detect the presence of individuals or objects, explain how they determine when to open or close the door, highlight their safety features, examine their integration capabilities with other security devices, explore their remote control capabilities, discuss maintenance requirements, and showcase their adaptability to different door types, sizes, and environmental conditions.

Working Principle

The working principle of an automatic door open and close system involves a combination of sensors, control mechanisms, and actuators. When a person or object approaches the door, the sensors detect their presence and send a signal to the control unit. The control unit then processes the signal and activates the actuators, which can be electric motors, hydraulic systems, or pneumatic systems, to open or close the door accordingly.

Main Components

The main components of an automatic door open and close system include:

Sensors: These sensors play a crucial role in detecting the presence of individuals or objects near the door. Infrared sensors emit infrared beams and detect interruptions in the beam caused by a person or object passing through. Microwave sensors emit microwave signals and measure the reflection of these signals to detect movement. Motion sensors use infrared technology to detect changes in heat patterns caused by the movement of individuals or objects.

Control Unit: The control unit acts as the brain of the system. It receives signals from the sensors and processes them to determine the appropriate action for the door. The control unit takes into account factors such as the distance of the person or object from the door, the direction of movement, and the programmed settings for the door’s operation.

Actuators: Actuators are responsible for physically opening or closing the door. They can be electric motors, hydraulic systems, or pneumatic systems. These actuators are controlled by the signals received from the sensors and the control unit.

Safety Sensors: Safety sensors are an essential component of automatic door opening and closing systems. They ensure the safety of individuals by detecting obstructions or obstacles in the door’s path. If an obstruction is detected, the system will stop the door from closing or reverse its direction to avoid causing harm.

Power Supply: The system requires a power source, typically electricity, to operate the sensors, control unit, and actuators. Backup power sources, such as batteries or generators, can be incorporated to ensure continuous operation during power outages.

Detection of Individuals or Objects

Automatic door open and close systems employ various sensors to detect the presence of individuals or objects. These sensors are strategically placed near the door and are designed to detect movement or changes in the environment. The sensors continuously monitor the area and send signals to the control unit when they detect the presence of someone or something. This allows the system to respond promptly and open or close the door as needed.
