1. Main controller: it is the command center of the automatic door. It sends out corresponding instructions through the large-scale integrated block with internal command program to command the motor or electric lock system; At the same time, people adjust the door opening speed, opening amplitude and other parameters through the main controller.

2、感应探测器：负责采集外部信号，如同人们的眼睛，当有移动的物体进入它的工作范围时，它就给主控制器一个脉冲信号;

2. Induction detector: it is responsible for collecting external signals, just like people's eyes. When a moving object enters its working range, it will send a pulse signal to the main controller;

3、动力马达：提供开门与关门的主动力，控制门扇加速与减速运行。

3. Power motor: it provides the main power for opening and closing the door, and controls the acceleration and deceleration of the door leaf.

4、门扇行进轨道：就象火车的铁轨，约束门扇的吊具走轮系统，使其按特定方向行进。

4. Door leaf travel track: like the railway track of a train, the spreader wheel system that restricts the door leaf to travel in a specific direction.

5、门扇吊具走轮系统:用于吊挂活动门扇，同时在动力牵引下带动门扇运行。

5. Door leaf spreader wheel system: used to hang the movable door leaf and drive the door leaf to run under power traction.

6、同步皮带(有的厂家使用三角皮带)：用于传输马达所产动力，牵引门扇吊具走轮系统。

6. Synchronous belt (triangular belt is used by some manufacturers): it is used to transmit the power produced by the motor and pull the door leaf spreader pulley system.

7、下部导向系统：是门扇下部的导向与定位装置，防止门扇在运行时出现前后门体摆动。

7. Lower guiding system: it is the guiding and positioning device at the lower part of the door leaf to prevent the front and rear door bodies from swinging during the operation of the door leaf.

当门扇要完成一次开门与关门，其工作流程如下：

When the door leaf is to be opened and closed at one time, the working process is as follows:

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 someone entering, it transmits the pulse signal to the main controller. After judgment, the main controller notifies the motor to run, and monitors the motor revolutions, so as to inform the motor to apply force and enter slow running at a certain time. After the motor gets a certain operating current, it runs in the forward direction, transmits the power to the synchronous belt, and then the synchronous belt transmits the power to the spreader system to open the door leaf; After the door leaf is opened, the controller makes a judgment. If it is necessary to close the door, inform the motor to move in the opposite direction and close the door leaf.
