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、感應探測器：負責采集外部信號，如同人們的眼睛，當有移動的物體進入它的工作范圍時，它就給主控制器一個脈沖信號;

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、動力馬達：提供開門與關門的主動力，控制門扇加速與減速運行。

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、門扇行進軌道：就象火車的鐵軌，約束門扇的吊具走輪系統，使其按特定方向行進。

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、門扇吊具走輪系統:用于吊掛活動門扇，同時在動力牽引下帶動門扇運行。

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

6、同步皮帶(有的廠家使用三角皮帶)：用于傳輸馬達所產動力，牽引門扇吊具走輪系統。

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、下部導向系統：是門扇下部的導向與定位裝置，防止門扇在運行時出現前后門體擺動。

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.

當門扇要完成一次開門與關門，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:

感應探測器探測到有人進入時，將脈沖信號傳給主控器，主控器判斷后通知馬達運行，同時監控馬達轉數，以便通知馬達在一定時候加力和進入慢行運行。馬達得到一定運行電流后做正向運行，將動力傳給同步帶，再由同步帶將動力傳給吊具系統使門扇開啟;門扇開啟后由控制器作出判斷，如需關門，通知馬達作反向運動，關閉門扇。

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.
