在酒店或者银行等场所经常会看到自动感应门的身影，当有人走近时，门会自动向两边打开，人走过之后门又自动关闭。那么自动感应门是如何实现自动开关的呢？下面济南感应门厂家为您分析：

Automatic sensing doors are often seen in hotels, banks and other places. When someone approaches, the doors will automatically open to both sides, and the doors will automatically close after people pass. So how does the automatic sensing door realize automatic opening and closing? The following is the analysis of Jinan Sensible Door manufacturer:

自动感应门功能的实现主要跟主控制器、感应探测器、动力马达和门扇行进轨道等部分有关。主控制器是自动感应门的指挥中心，通过对其内部大规模集成电路的编程设定，主控制器可以发出相应指令，指挥动力马达进行相关动作。

The realization of the automatic induction door function is mainly related to the main controller, induction detector, power motor and door leaf travel track. The main controller is the command center of the automatic induction door. Through the programming of its internal large-scale integrated circuit, the main controller can send corresponding instructions to command the power motor to carry out relevant actions.

同时人们也可以通过控制器来调节门扇的开启速度和开启幅度等参数；感应探测器主要负责采集外部信号，分为微波雷达探测器和红外探测器两种。

At the same time, people can also adjust the opening speed and opening amplitude of the door leaf through the controller; The induction detector is mainly responsible for collecting external signals, which is divided into microwave radar detector and infrared detector.

微波雷达探测器主要针对移动物体，通过发射雷达脉冲来探测一定的范围，当有移动物体进入探测范围时，它就给主控制器发送脉冲信号，继而由主控制器进行判断并执行下一步操作。

The microwave radar detector mainly aims at moving objects and detects a certain range by transmitting radar pulses. When a moving object enters the detection range, it sends pulse signals to the main controller, which then judges and performs the next operation.

微波雷达探测器的优点在于开门迅速，缺点在于只能检测到移动物体，当人站在门下长时间不动时，门便无法自动打开。

The advantage of microwave radar detector is that it can open the door quickly, but the disadvantage is that it can only detect moving objects. When people stand under the door for a long time, the door cannot open automatically.

红外探测器则是检测特定范围内的物体，不管人员是否移动，只要处于观测范围内，它都会向主控制系统发送开门信号，其缺点是红外传感器的反应速度较慢，适用于行动迟缓的人员出入的场所；动力马达主要提供开门与关门的主动力，控制门扇加速与减速运动；门扇行进轨道就像是火车运行的铁轨一样，主要作用是约束门扇的吊具走轮系统，使其按特定方向行进。

The infrared detector is used to detect objects within a specific range. As long as it is within the observation range, it will send a door opening signal to the main control system, regardless of whether the person is moving or not. Its disadvantage is that the infrared sensor has a slow response speed, which is suitable for places where people who are slow to move in and out; The power motor mainly provides the main power for opening and closing the door, and controls the acceleration and deceleration of the door leaf; The travel track of the door leaf is like the railway track of the train. Its main function is to constrain the lifting gear wheel system of the door leaf to move in a specific direction.

当自动感应门的感应探测器探测到有人进入时，就会发送开门信号给主控制器，主控制器判断后通知马达运行，同时主控制器会监测马达运行转数，以便通知马达在一定时候加力或进入慢行运行状态。

When the induction detector of the automatic induction door detects someone entering, it will send the door opening signal to the main controller. The main controller will notify the motor to run after judging. At the same time, the main controller will monitor the running speed of the motor, so as to inform the motor to apply force or enter the slow running state at a certain time.

马达在得到工作信号后，正向运行使门开启。门扇开启后，探测器继续对探测范围进行检测，当一定时间内没有人员进入时，主控制器会做出判断，通知马达作反向运动，关闭门扇。

After receiving the working signal, the motor first runs forward to open the door. After the door leaf is opened, the detector continues to detect the detection range. When no one enters within a certain period of time, the main controller will make a judgment and notify the motor to make a reverse movement and close the door leaf.

自动感应门的应用非常广泛，主要适合于宾馆、酒店、银行、写字楼、医院和商店等。使用自动感应门，可以节约空调能源、降低噪音、防风、防尘，同时可以使出入口显得庄重美观。您有需求就来我们网站http://www.jnkdblgd.com咨询了解或选购吧！
