卷帘门开门时怎么发生感应的你知道吗?相信很多对门业不了解的朋友 也都不能这一问题,那么今天我们济南电动卷帘门厂家就给大家细细说来,希望通过我们的介绍能增加你对该门的了解。
Do you know how induction occurs when rolling shutter door is opened? I believe many friends who don't know about door industry can't solve this problem, so today we Jinan electric rolling shutter door manufacturers will tell you in detail, hope that through our introduction can increase your understanding of the door.
1、卷帘门的开门感应信号为触点信号,微波雷达和红外线传感器是常用的两种信号源:微波雷达是对物体的位移反应,因此反应速度快,适用于行走速度正常的人通过的地方,其特点是一旦靠近门的人不想离开,而又静止不动,雷达便不再作出反应,卷帘门就会关闭,对门机具有一定的保护作用;红外线传感器是对物体的存在作出反应,无论人是否移动,只要在传感器的扫描范围内,它都会作出反应,即传出触点信号。不足之处是红外线传感器反应速度慢,适合于行动迟缓的人员进出。
1. The opening induction signal of rolling shutter door is contact signal. Microwave radar and infrared sensor are two common signal sources: microwave radar is the displacement response of objects, so the response speed is fast. It is suitable for people with normal walking speed to pass through. Its characteristic is that once the people close to the door do not want to leave, but still, the radar will no longer react, and the rolling shutter door will close Closed, has a certain protective effect on the door machine; infrared sensor is to respond to the existence of objects, whether people move or not, as long as it is within the scanning range of the sensor, it will respond, that is, it will send out contact signal. The disadvantage is that the infrared sensor has a slow response speed, which is suitable for slow-moving personnel.

2.如果卷帘门接收接触感应信号的时间太长,控制器将认为信号输入系统有故障。并且自动移门如果长期保持打开状态,还会对电气元件造成损坏。因为微波雷达和红外线传感器不知道那些靠近卷帘门的人是否真的会进来,所以有些情况下更愿意使用按钮开关。
2. If the roller shutter receives the contact induction signal for a long time, the controller will consider that the signal input system is faulty. And if the automatic moving door remains open for a long time, it will cause damage to the electrical components. Because microwave radars and infrared sensors don't know if people who are close to the shutter door will really come in, they prefer to use the button switch in some cases.
按钮开关可以是一种接触式的按钮,更便于称为肘触开关。手肘开关的使用寿命很长,尤其是能用手肘操作。不与手接触。也有脚踩开关,同样的功能,但是对防水的要求更高,而且脚踩的力量更大,容易使脚踩开关失效。也有一种带有一个触点开关的拉手,当它被推(或在反方向拉)时,它将触点信号传递给门机。
The button switch can be a contact type button, which is more convenient to be called elbow touch switch. The service life of elbow switch is very long, especially it can be operated with elbow. Do not touch hands. There is also a foot switch, which has the same function, but it has higher requirements for waterproof, and the force of foot is greater, so it is easy to make the foot switch fail. There is also a handle with a contact switch. When it is pushed (or pulled in the opposite direction), it transmits the contact signal to the gantry crane.
如今,建筑自控系统有时会有特别的要求,比如通过电话的一条线来控制开门。为了满足这一要求,只需确保信号为被动接触信号。有的时候,人们会要求用遥控天线。
Nowadays, building automatic control system sometimes has special requirements, such as controlling the door through a line of telephone. In order to meet this requirement, we only need to ensure that the signal is a passive contact signal. Sometimes, people will ask for remote control antenna.
通过一台无线收音机与卷帘门进行接触式连接,再配一台无线收音机,即可达到要求。然而,现在有太多的无线电波源,很容易造成偶然打开门的麻烦。计时器可以电动控制门的状态,原理是把时钟连接到一个特殊的开关电路上,在设定的时间内卷帘门可以自动打开或锁上。
Through a wireless radio and rolling door contact connection, and then with a wireless radio, can meet the requirements. However, now there are too many radio wave sources, it is easy to cause the trouble of accidentally opening the door. The timer can electrically control the state of the door. The principle is to connect the clock to a special switch circuit. The rolling shutter door can be opened or locked automatically within the set time.
以上给大家介绍的济南卷帘门开门时是怎么发生感应的相关问题,相信阅读完本篇文章大家都已经有了很深刻的了解,卷帘门的开门感应信号为触点信号,它将触点信号传递给门机,也可使用遥控进行操作。
I believe that after reading this article, we have a very deep understanding. The door opening induction signal of the rolling shutter door is the contact signal, which transmits the contact signal to the door machine, and can also be operated by remote control.
