          卷簾門開門時怎么發生感應的你知道嗎?

          卷簾門開門時怎么發生感應的你知道嗎?相信很多對門業不了解的朋友 也都不能這一問題,那么今天我們濟南卷簾門廠家就給大家細細說來,希望通過我們的介紹能增加你對該門的了解。
          Do you know how the roller shutter door opens? I believe many friends who don't know about the door industry can't solve this problem, so today we Jinan roller shutter door manufacturers will tell you in detail, hope that through our introduction can increase your understanding of the door.
          1、卷簾門的開門感應信號為觸點信號,微波雷達和紅外線傳感器是常用的兩種信號源:微波雷達是對物體的位移反應,因此反應速度快,適用于行走速度正常的人通過的地方,其特點是一旦靠近門的人不想離開,而又靜止不動,雷達便不再作出反應,卷簾門就會關閉,對門機具有一定的保護作用;紅外線傳感器是對物體的存在作出反應,無論人是否移動,只要在傳感器的掃描范圍內,它都會作出反應,即傳出觸點信號。不足之處是紅外線傳感器反應速度慢,適合于行動遲緩的人員進出。
          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.如果卷簾門接收接觸感應信號的時間太長,控制器將認為信號輸入系統有故障。并且自動移門如果長期保持打開狀態,還會對電氣元件造成損壞。因為微波雷達和紅外線傳感器不知道那些靠近卷簾門的人是否真的會進來,所以有些情況下更愿意使用按鈕開關。按鈕開關可以是一種接觸式的按鈕,更便于稱為肘觸開關。
          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. The button switch can be a contact type button, which is more convenient to be called elbow touch switch.
          手肘開關的使用壽命很長,尤其是能用手肘操作。不與手接觸。也有腳踩開關,同樣的功能,但是對防水的要求更高,而且腳踩的力量更大,容易使腳踩開關失效。也有一種帶有一個觸點開關的拉手,當它被推(或在反方向拉)時,它將觸點信號傳遞給門機。如今,建筑自控系統有時會有特別的要求,比如通過電話的一條線來控制開門。為了滿足這一要求,只需確保信號為被動接觸信號。有的時候,人們會要求用遙控天線。
          The service life of elbow switch is very long, especially it can be operated with elbow. Do not touch hands. But it's easier to step on the switch, and it's more waterproof. 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. 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.
          通過一臺無線收音機與卷簾門進行接觸式連接,再配一臺無線收音機,即可達到要求。然而,現在有太多的無線電波源,很容易造成偶然打開門的麻煩。計時器可以電動控制門的狀態,原理是把時鐘連接到一個特殊的開關電路上,在設定的時間內卷簾門可以自動打開或鎖上。
          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.
          以上給大家介紹的卷簾門開門時是怎么發生感應的相關問題,相信閱讀完本篇文章大家都已經有了很深刻的了解,卷簾門的開門感應信號為觸點信號,它將觸點信號傳遞給門機,也可使用遙控進行操作。
          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.
