卷簾門的開門信號你知道嗎？很多朋友不了解這個問題，下面就讓濟南卷簾門廠來講講卷簾門的開門信號的相關內容吧。

　　Do you know the opening signal of rolling shutter door? Many friends do not understand this problem. Let jinan shutter door factory talk about the relevant content of the opening signal of the shutter door.

　　卷簾門的開門信號是觸點信號，微波雷達和紅外傳感器是常用的兩種信號源：

　　The opening signal of rolling shutter door is contact signal, microwave radar and infrared sensor are two commonly used signal sources:

　　微波雷達是對物體的位移反應，因而反應速度快，適用于行走速度正常的人員通過的場所，它的特點是一旦在門附近的人員不想出門而靜止不動后，雷達便不再反應，卷簾門就會關閉，對門機有一定的保護作用；紅外傳感器對物體存在進行反應，不管人員移動與否，只要處于傳感器的掃描范圍內，它都會反應即傳出觸點信號。缺點是紅外傳感器的反應速度較慢，適用于有行動遲緩的人員出入的場所。

　　Microwave radar is the displacement response of the object, so the reaction speed is fast, suitable for people with normal walking speed through the place, its characteristics is that once the people near the door do not want to go out and remain still, the radar will no longer react, the rolling shutter door will close, has a certain protective effect on the door machine; Infrared sensors react to the presence of objects, no matter whether people move or not, as long as they are in the scanning range of the sensor, it will respond to the outgoing contact signal. The disadvantage is that the reaction speed of the infrared sensor is slow, and it is suitable for the places with slow personnel.

　　如果卷簾門接受觸點信號時間過長，控制器會認為信號輸入系統出現障礙。而且自動平移門如果保持開啟時間過長，也會對電氣部件產生損害。由于微波雷達和紅外傳感器并不了解接近卷簾門的人是否真要進門，所以有些場合更愿意使用按鍵開關。按鍵開關可以是一個觸點式的按鈕，更方便的是所謂肘觸開關。肘觸開關很耐用，特別是它可以用胳膊肘來操作，避免了手的接觸。

　　If the rolling shutter door receives the contact signal for too long, the controller will think that the signal input system has obstacles. And if the automatic translation door is kept open for too long, it will also cause damage to the electrical components. Because microwave radar and infrared sensors do not know whether people close to the shutter door really want to enter the door, so some occasions are more willing to use the button switch. Key switch can be the button of a touch type, more convenient is so-called elbow touch switch. Toggle switch is very durable, especially it can be operated by elbow, avoid hand contact.

　　還有腳踏開關，功能一樣，但對防水的要求較高，而且腳踏的力量很大，容易使腳踏開關失效。還有一種帶觸點開關的拉手，當拉手被推(或在反方向拉)到位時，向門機提供觸點信號。

　　There is a foot switch, the same function, but the waterproof requirements are higher, and the strength of the foot is very large, easy to make the foot switch failure. There is also a handle with a contact switch that provides a contact signal to the door machine when the handle is pushed (or pulled in the opposite direction) into place.

　　濟南卷簾門廠提醒大家，現在的樓宇自控有時會提出特殊的要求，例如使用電話的某一分線控制開門。要達到這個要求，只要保證信號是無源的觸點信號即可。有些情況下，人們會提出天線遙控的要求。用一個無線接受器與卷簾門進行觸點式連接，再配一個無線發射器，就可以達到要求。

　　Nowadays, building automation sometimes puts forward special requirements, such as the use of a telephone line to control the opening of the door. To achieve this requirement, just ensure that the signal is passive contact signal. In some cases, people will ask for remote control of the antenna. Contact connection with a wireless receiver and rolling shutter door, coupled with a wireless transmitter, can meet the requirements.

　　不過，現在的無線電波源太多，容易導致偶然開門是一個麻煩的問題。定時器可以電動控制門的狀態，其原理是將時鐘與特定的開關電路相連，可預設定時間將卷簾門處于自動開啟或鎖門狀態。

　　However, there are so many sources of radio waves that opening doors accidentally is a troublesome problem. The timer can electrically control the state of the door. Its principle is to connect the clock with a specific switching circuit, and the rolling shutter door can be automatically opened or locked at a preset time.
