Lidar control automatic door switch scheme

Automatic door refers to the door that can be controlled by means of electricity or air pressure to open and close the door to facilitate personnel access. It is an intelligent door, which can sense the entry and exit of personnel according to human body sensors, infrared rays, 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 essential facilities in modern buildings.


Automatic doors are divided into sliding doors, translation doors, revolving doors and folding doors according to the way of opening and closing. Among them:

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

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

3. Revolving door: also known as cheese door, the door door rotates and closes along the center, which is generally used for 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 leaving.

4. Folding door: also known as folding automatic door, which belongs to a sliding door. The door is subdivided with multiple doors, which can be freely folded and opened. Usually used in shopping malls, exhibitions, conference halls and other places, can greatly save space.

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



The application of LiDAR in automatic door switching schemes usually has two aspects:


Light curtain detection: LiDAR can create an invisible "light curtain" by firing a laser beam and detecting the light it reflects. When someone passes through this light curtain, the lidar immediately detects it and transmits the signal to the door controller. The door controller controls the opening and closing of the door according to the received signal, so that people can freely enter and exit.

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 according to the direction and speed of the target object. This solution is particularly useful in places with large traffic, such as airports and shopping malls.


In general, the application of Lidar in the automatic door switching scheme can improve the safety, stability and response speed of the automatic door, so as to better serve the needs of users.

MVR3EB Laser ranging module has technical advantages for this application:


1. High-speed ranging: The use of TOF(time-of-flight Time of Flight) technology can achieve 0.3 to 14 meters /28 meters high-speed ranging needs (indoor and outdoor), faster than the traditional ranging technology, faster response speed, can detect personnel in and out faster.

2. Accuracy: The centimeter-level accuracy of the laser ranging module can provide high-precision data, making the control of the automatic door more accurate, and accurately judging whether the personnel are in and out, so as to better protect the use of the automatic door.

3. Compact size: Miniaturization is suitable for embedded development, easy to install and debug. It can be easily built into the automatic door structure, thus achieving a highly integrated and compact design, reducing the space and workload of installation.

4. Compatibility: The module provides HEX and ASCII two UART serial port output data formats, which can be compatible with different types of gate controllers, so as to achieve better adaptability and application flexibility.

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

6. High resolution: the resolution is 10mm, which can more accurately capture the dynamic changes of personnel entering and leaving the door, so as to more accurately judge the entry and exit of personnel.

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

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