自动门，顾名思义，是能够完成自动开合的门扇，在人们接近或是离开的时候，门扇的识别控制系统会将信号传递到控制单元，再通过驱动将门开启和关闭，并对开启和关闭的过程实现控制的系统。

Automatic door, as the name implies, is a door leaf that can automatically open and close. When people approach or leave, the identification control system of the door will transmit the signal to the control unit, and then open and close the door by driving, and control the process of opening and closing.

自动门从理论上理解应该是门的概念的延伸，是门的功能根据人的需要所进行的发展和完善。的自动门已经发展的非常成熟。

In theory, the automatic door should be the extension of the concept of door, and the development and improvement of the function of the door according to the needs of people. Automatic door has been developed very mature.

自动门的基本组成大体上相同，有了以上构成，再加上开门信号，就可以配置成一套简单的自动门系统了，就是可以将人接近门的动作识别为开门信号的控制单元，通过驱动系统将门开启，在人离开后再将门自动关闭，并对开启和关闭的过程实现控制的系统。通常情况下，不同种类的自动门其工作原理有一些不同，具体如下。

The basic composition of the automatic door is basically the same. With the above composition and the door opening signal, it can be configured into a set of simple automatic door system, which can recognize the action of people approaching the door as the control unit of opening signal, open the door through the drive system, close the door automatically after the person leaves, and control the process of opening and closing. Usually, the working principle of different types of automatic doors is different, as follows.

1、自动门感应器工作原理：

1. Working principle of automatic door sensor:

自动门感应器探测到有人进入时，将脉冲信号传给主控器，主控器判断后通知马达运行，同时监控马达转数，以便通知马达在一定时候加力和进入慢行运行。马达得到一定运行电流后做正向运行，将动力传给同步带，再由同步带将动力传给吊具系统使门扇开启；门扇开启后由控制器作出判断，如需关门，通知马达作反向运动，关闭门扇。

When the automatic door sensor detects that someone is entering, it will send the pulse signal to the main controller. After the master controller judges, it will inform the motor to run, and at the same time monitor the motor speed, so as to inform the motor to apply force and enter into slow running at a certain time. After getting a certain running current, the motor will run in forward direction and transmit the power to the synchronous belt, and then the synchronous belt will transmit the power to the spreader system to open the door; after the door leaf is opened, the controller will make a judgment. If it is necessary to close the door, the motor will be informed to move in reverse direction to close the door.

2、平移自动门原理：

2. Principle of translation automatic door:

感应探测器探测到有人进入时，将脉冲信号传给主控器，主控器判断后通知马达运行，同时监控马达转数，以便通知马达在一定时候加力和进入慢行运行。马达得到一定运行电流后做正向运行，将动力传给同步带，再由同步带将动力传给吊具系统使门扇开启；门扇开启后由控制器作出判断，如需关门，通知马达作反向运动，关闭门扇。

When the induction detector detects that someone enters, the pulse signal will be transmitted to the main controller. After the master controller judges, it will inform the motor to run, and at the same time monitor the motor speed, so as to inform the motor to increase force and enter into slow running at a certain time. After getting a certain running current, the motor will run in forward direction and transmit the power to the synchronous belt, and then the synchronous belt will transmit the power to the spreader system to open the door; after the door leaf is opened, the controller will make a judgment. If it is necessary to close the door, the motor will be informed to move in reverse direction to close the door.

3、红外线自动门原理：

3. Principle of infrared automatic door:

一般人体都有恒定的体温，一般在37度，所以会发出特定波长10UM左右的红外线，红外线自动门就是利用红外反射原理，电路中有一个发射模块和一个接收模块，发射模块能发出一定频率及一定功率的红外光，当遇到障碍物时，反射回来，被接受模块收到，经过电路或单片机处理，执行相应的功能。

Generally, the human body has a constant body temperature, which is usually at 37 degrees, so it will send out infrared light with a specific wavelength of about 10um. The infrared automatic door is based on the principle of infrared reflection. There are a transmitting module and a receiving module in the circuit. The transmitting module can send out infrared light with a certain frequency and a certain power. When encountering obstacles, it will reflect back and be received by the receiving module and pass through the circuit Or SCM processing, the implementation of the corresponding functions.
