卷簾門(mén)的開(kāi)門(mén)信號(hào)你知道嗎？很多朋友不了解這個(gè)問(wèn)題，下面就讓濟(jì)南卷簾門(mén)廠來(lái)講講卷簾門(mén)的開(kāi)門(mén)信號(hào)的相關(guān)內(nèi)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(mén)的開(kāi)門(mén)信號(hào)是觸點(diǎn)信號(hào)，微波雷達(dá)和紅外傳感器是常用的兩種信號(hào)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(dá)是對(duì)物體的位移反應(yīng)，因而反應(yīng)速度快，適用于行走速度正常的人員通過(guò)的場(chǎng)所，它的特點(diǎn)是一旦在門(mén)附近的人員不想出門(mén)而靜止不動(dòng)后，雷達(dá)便不再反應(yīng)，卷簾門(mén)就會(huì)關(guān)閉，對(duì)門(mén)機(jī)有一定的保護(hù)作用；紅外傳感器對(duì)物體存在進(jìn)行反應(yīng)，不管人員移動(dòng)與否，只要處于傳感器的掃描范圍內(nèi)，它都會(huì)反應(yīng)即傳出觸點(diǎn)信號(hào)。缺點(diǎn)是紅外傳感器的反應(yīng)速度較慢，適用于有行動(dòng)遲緩的人員出入的場(chǎng)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(mén)接受觸點(diǎn)信號(hào)時(shí)間過(guò)長(zhǎng)，控制器會(huì)認(rèn)為信號(hào)輸入系統(tǒng)出現(xiàn)障礙。而且自動(dòng)平移門(mén)如果保持開(kāi)啟時(shí)間過(guò)長(zhǎng)，也會(huì)對(duì)電氣部件產(chǎn)生損害。由于微波雷達(dá)和紅外傳感器并不了解接近卷簾門(mén)的人是否真要進(jìn)門(mén)，所以有些場(chǎng)合更愿意使用按鍵開(kāi)關(guān)。按鍵開(kāi)關(guān)可以是一個(gè)觸點(diǎn)式的按鈕，更方便的是所謂肘觸開(kāi)關(guān)。肘觸開(kāi)關(guān)很耐用，特別是它可以用胳膊肘來(lái)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(kāi)關(guān)，功能一樣，但對(duì)防水的要求較高，而且腳踏的力量很大，容易使腳踏開(kāi)關(guān)失效。還有一種帶觸點(diǎn)開(kāi)關(guān)的拉手，當(dāng)拉手被推(或在反方向拉)到位時(shí)，向門(mén)機(jī)提供觸點(diǎn)信號(hào)。

　　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(jì)南卷簾門(mén)廠提醒大家，現(xiàn)在的樓宇自控有時(shí)會(huì)提出特殊的要求，例如使用電話的某一分線控制開(kāi)門(mén)。要達(dá)到這個(gè)要求，只要保證信號(hào)是無(wú)源的觸點(diǎn)信號(hào)即可。有些情況下，人們會(huì)提出天線遙控的要求。用一個(gè)無(wú)線接受器與卷簾門(mén)進(jìn)行觸點(diǎn)式連接，再配一個(gè)無(wú)線發(fā)射器，就可以達(dá)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(guò)，現(xiàn)在的無(wú)線電波源太多，容易導(dǎo)致偶然開(kāi)門(mén)是一個(gè)麻煩的問(wèn)題。定時(shí)器可以電動(dòng)控制門(mén)的狀態(tài)，其原理是將時(shí)鐘與特定的開(kāi)關(guān)電路相連，可預(yù)設(shè)定時(shí)間將卷簾門(mén)處于自動(dòng)開(kāi)啟或鎖門(mén)狀態(tài)。

　　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.
