Applications

An automatic door is a door that can be controlled by electricity or air pressure to facilitate the entry and exit of personnel. It is an intelligent door that can sense the entry and exit of personnel according to human sensors, infrared, radar and other equipment, and control the opening and closing of the door, so as to improve the efficiency and safety of the door. Automatic doors are widely used in shopping malls, hotels, hospitals, airports, office buildings and other places, and are one of the indispensable facilities in modern buildings.

Automatic doors are divided into sliding doors, sliding doors, revolving doors and folding doors according to the opening and closing methods. Thereinto:

1. Sliding door: also known as sliding door, usually used for indoor and store entrances, the door leaf is pushed open and closed in the horizontal direction, and the structure is simple, easy to install and maintain.

2. Sliding door: also known as sliding automatic door, the door leaf opens and closes in the vertical direction, usually used in store entrances, public buildings, hospitals, shopping malls and other places, with the advantages of beauty, safety, energy saving, etc., can meet the needs of different installation sites.

3. Revolving door: also known as cheese door, the door leaf rotates and closes along the center, which is generally used in places with large flow of people, parking lots, hotels and other places, which can effectively control the air flow and ensure the safety of people entering and exiting.

4. Folding door: also known as folding automatic door, it is a kind of sliding door. The door leaf is subdivided by multiple door leaves, which can be folded and closed freely. It is usually used in shopping malls, exhibitions, conference halls and other places, which can greatly save space.

In addition, there are some special types of automatic doors, such as curtain automatic doors, medical airtight doors, etc., which have different uses.

The application of LiDAR in automatic door opening and closing solutions usually has two aspects:

Light curtain detection: Lidar can create an invisible "light curtain" by emitting a laser beam and detecting the light it reflects. When a person passes through this light curtain, the lidar immediately detects and transmits 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 realize the radar tracking function, which can display the target object on the screen with coordinates relative to the radar system, and then control the opening and closing of the automatic door according to the direction and speed of the target object. This solution is especially useful in high-traffic places, such as airports, shopping malls, etc.

In general, the application of LiDAR in automatic door opening and closing solutions can improve the safety, stability and response speed of automatic doors, so as to better serve user needs.

Siman Recommended Model:

Advantages of SDAM laser ranging module for this application technology:

1. High-speed ranging: D TOF (Time-of-Flight) technologyIt can achieve high-speed ranging requirements from 0.3 to 22 meters (indoor and outdoor), which is faster and more responsive than traditional ranging technology, and can detect the entry and exit of people faster.

2. Accuracy: The centimeter-level accuracy of the laser ranging module can provide high-precision data, make the control of the automatic door more accurate, and accurately judge whether the personnel enter and exit, so as to better ensure the use of the automatic door.

3. Small size: Miniaturization is suitable for embedded development, easy to install and debug. It can be easily built into the automatic door structure, resulting in a highly integrated and compact design that reduces the space and effort required for installation.  

4. UART serial port and I²C output: The SDAM laser ranging module provides a communication protocol, which can be easily integrated into the smart public toilet management system.

5. Safety: The use of 940nm VCSEL light source is a type of safety laser, no radiation, safe and reliable, and will not cause harm to the human body, so it can ensure safety.  

6. High resolution: the resolution is 1mm, which can accurately capture the dynamic changes of personnel entering and exiting, so as to judge the entry and exit of personnel more accurately.

7. Low cost: The price of the module is relatively low, and due to its high reliability and easy maintenance, it reduces the cost of later maintenance and replacement, and can achieve high cost performance.

8. Wide applicability: It is suitable for automatic door control in different indoor and outdoor places, such as shopping malls, hotels, hospitals, airports, office buildings, etc., which can meet the needs of different scenarios.
