Automatic door refers to a door that can be controlled by electricity or air pressure to facilitate personnel access. It is an intelligent door that can sense the entry and exit of people based on human sensors, infrared, radar and other devices, and control the opening and closing of the door, thereby improving the efficiency and safety of door use. Automatic doors are widely used in shopping malls, hotels, hospitals, airports, office buildings, and other places, and are one of the essential facilities in modern buildings.
Automatic doors are divided into sliding doors, sliding doors, revolving doors, folding doors, and other types according to their opening and closing methods. Among them:
1. Sliding door: also known as sliding door, usually used for indoor and store entrances. The door leaf opens and closes horizontally, with a simple structure and easy installation and maintenance.
2. Sliding door: also known as sliding automatic door, the door leaf opens and closes in the vertical direction, usually used in places such as store entrances, public buildings, hospitals, shopping malls, etc. It has the advantages of beauty, safety, energy saving, etc., and can meet the needs of different installation sites.
3. Rotating door: also known as cheese door, the door leaf rotates and opens along the center, generally used in places with high pedestrian flow, parking lots, hotels, etc. It can effectively control air flow while ensuring the safety of people entering and exiting.
4. Folding door: also known as folding automatic door, it belongs to a type of sliding door. The door leaf is divided into multiple pieces and can be freely folded and opened. Usually used in shopping malls, exhibitions, conference halls, and other places, it can greatly save space.
In addition, there are some special types of automatic doors, such as curtain automatic doors, medical airtight doors, etc., with different purposes.
The application of LiDAR in automatic door opening and closing schemes usually has two aspects:
Light curtain detection:Lidar can create an invisible 'light curtain' by emitting a laser beam and detecting its reflected light. When someone passes through this light curtain, the LiDAR will immediately detect and transmit the signal to the door controller. The door controller controls the opening and closing of the door based on the received signal, allowing people to enter and exit freely.
Radar tracking:Lidar can also achieve radar tracking function, which can display the target object on the screen in coordinates relative to the radar system, and then control the opening and closing of the automatic door based on the direction and speed of the target object's movement. This solution is particularly practical in places with high pedestrian traffic, such as airports, shopping malls, etc.
Overall, the application of LiDAR in automatic door opening and closing schemes can improve the safety, stability, and response speed of automatic doors, thereby better serving user needs.
