The automatic door itself is equipped with an induction probe, which can send infrared signal or microwave signal. When this signal is reflected by a closed object, it will automatically turn on and off. When the induction detector detects someone entering, the induction detector will collect signals and generate pulse signals, and then transmit them to the main controller.

主控制器判斷后，會通知電機(jī)運(yùn)行，同時(shí)監(jiān)控電機(jī)的轉(zhuǎn)數(shù)，從而通知電機(jī)施力，在一定時(shí)間內(nèi)緩慢運(yùn)行。電機(jī)得到一定的運(yùn)行電流后，向前運(yùn)行，將動(dòng)力傳遞給同步帶，然后同步帶將動(dòng)力傳遞給吊具系統(tǒng)，打開門扇;門扇打開后，控制器會做出判斷。如果有必要關(guān)門，通知電機(jī)反向運(yùn)動(dòng)并關(guān)閉門扇。

After judgment, the main controller will notify the motor to run and monitor the number of revolutions of the motor, so as to inform the motor to apply force and run slowly within a certain time. After the motor gets a certain operating current, it runs forward and transmits the power to the synchronous belt, and then the synchronous belt transmits the power to the spreader system and opens the door leaf; After the door leaf is opened, the controller will make judgment. If it is necessary to close the door, inform the motor to move in the opposite direction and close the door leaf.

二、自動(dòng)感應(yīng)門的構(gòu)成結(jié)構(gòu)：

2、 Composition of automatic induction door:

感應(yīng)門有很多種。這里以平移感應(yīng)自動(dòng)門機(jī)為例，介紹一下它的組成：

There are many kinds of induction doors. Here, take the translation induction automatic door machine as an example to introduce its composition:

(1)主控制器：是自動(dòng)門的指揮中心，通過內(nèi)置指令程序的大型集成塊，發(fā)出相應(yīng)的指令，命令電機(jī)或電鎖系統(tǒng)工作;同時(shí)，人們通過主控制器調(diào)節(jié)開啟速度、開啟幅度等參數(shù)。

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

(2)感應(yīng)探測器：主要分為微波傳感器和紅外傳感器兩種。它負(fù)責(zé)采集外界信號，就像人的眼睛一樣。當(dāng)在其工作范圍內(nèi)有一個(gè)運(yùn)動(dòng)物體進(jìn)入時(shí)，它給主控制器一個(gè)脈沖信號。

(2) Induction detector: it is mainly divided into microwave sensor and infrared sensor. It is responsible for collecting external signals, just like human eyes. When a moving object enters within its working range, it sends a pulse signal to the main controller.

(3)動(dòng)力電機(jī)：提供開關(guān)門的主要驅(qū)動(dòng)力，控制門扇的加速和減速。

(3) Power motor: it provides the main driving force for opening and closing the door and controls the acceleration and deceleration of the door leaf.

(4)門扇行駛軌跡：就像火車的軌道一樣，約束門扇的吊索輪系統(tǒng)，使其向特定方向行駛。

(4) Door leaf travel path: like the track of a train, the sling wheel system constrains the door leaf to travel in a specific direction.

(5)門扇吊具行走輪系統(tǒng)：用于懸掛活動(dòng)門扇，驅(qū)動(dòng)門扇在動(dòng)力牽引下運(yùn)行。

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

(6)同步帶(有的廠家用V帶):用來傳遞電機(jī)產(chǎn)生的動(dòng)力，拉動(dòng)門扇吊具的車輪運(yùn)行系統(tǒng)。

(6) Synchronous belt (V-belt used by some manufacturers): it is a wheel running system used to transfer the power generated by the motor and pull the door leaf spreader.

(7)下導(dǎo)向系統(tǒng)：是門扇下部的導(dǎo)向和定位裝置，防止門扇運(yùn)行時(shí)前后門體擺動(dòng)。

(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 when the door leaf is running.

(8)感應(yīng)門機(jī)安裝在自動(dòng)感應(yīng)門中，是控制自動(dòng)門開關(guān)的一系列部件的統(tǒng)稱;

(8) Induction door machine is installed in the automatic induction door, which is the general name of a series of components controlling the automatic door switch;

也稱為自動(dòng)門單元或感應(yīng)門單元;感應(yīng)門座起重機(jī)的部件一般包括：電機(jī)、控制器、掛輪、皮帶和導(dǎo)軌。

Also known as automatic door unit or induction door unit; The components of induction portal crane generally include: motor, controller, hanging pulley, belt and guide rail.

以上是自動(dòng)感應(yīng)門的工作原理和結(jié)構(gòu)介紹。希望大家在生活中能更好的應(yīng)用。同時(shí)，感應(yīng)門應(yīng)用廣泛，相信未來的發(fā)展前景將會變的越來越好。

The above is the working principle and structure of automatic induction door. I hope you can better apply it in your life. At the same time, the induction door is widely used. I believe that the future development prospect will become better and better.
