電動(dòng)卷簾門多遠(yuǎn)能控制開關(guān)

來源:http:// 日期:2021-03-02 發(fā)布人:
當(dāng)前,電氣化時(shí)代的卷簾門都是可以遙控的,但是遙控的距離與設(shè)備的種類有很大的關(guān)聯(lián),不同類型的設(shè)備種類有不同的控制距離。那么,卷簾門遙控器可以控制多遠(yuǎn)的距離呢?了解這個(gè)問題之前,我們需要先了解無線電信號(hào)這個(gè)概念。
At present, the rolling shutter doors in the era of electrification can be controlled by remote control, but the distance of remote control is greatly related to the types of equipment, and different types of equipment have different control distances. So, how far can the remote control of rolling shutter door control? Before we can understand this problem, we need to understand the concept of radio signal.

無線電遙控常用的載波頻率為315mHz或者433mHz,遙控器使用的是規(guī)定的開放頻段,在這一頻段內(nèi),發(fā)射功率小于10mW、覆蓋范圍小于100m或不超過本單位范圍的,可以不必經(jīng)過“無線電管理委員會(huì)”審批而自由使用。也就是說,如果你有需要,可以在本單位的院落內(nèi)任何一個(gè)位置控制卷簾門的開關(guān),如果是公共區(qū)域的店鋪,就要受到100米的數(shù)據(jù)限制,超過100米就要經(jīng)無線電管理委員會(huì)審批了。說是審批,即使你有再多的理由也不可能通過,因?yàn)橐粋€(gè)小小的卷簾門怎么可能有超遠(yuǎn)距離開關(guān)門的需求呢。
The carrier frequency commonly used for radio remote control is 315MHz or 433MHz. The remote control uses the open frequency band specified by the state. In this frequency band, if the transmission power is less than 10MW, the coverage is less than 100m or does not exceed the scope of the unit, it can be used freely without the approval of the "Radio Management Committee". That is to say, if you need to, you can control the switch of the rolling shutter door at any position in the courtyard of your unit. If it is a shop in a public area, it will be subject to the data limit of 100 meters. If it is more than 100 meters, it will be approved by the radio management committee. Even if you have more reasons, it is impossible to pass the examination and approval, because how can a small rolling door have the need to close the door from a distance.
如果是100米范圍內(nèi),一般可以通過選擇卷簾門信號(hào)接收器和遙控器的功率就可以進(jìn)行確定和調(diào)整。目前,大多數(shù)卷簾門的控制距離都是30——50米的距離,這個(gè)距離已經(jīng)完全夠用了。當(dāng)遙控器電池電量不足時(shí),會(huì)出現(xiàn)控制距離下降的現(xiàn)象。
If it is within 100 meters, it can be determined and adjusted by selecting the power of the rolling door signal receiver and remote control. At present, the control distance of most roller shutter doors is 30-50 meters, which is enough. When the battery power of the remote controller is insufficient, the control distance will drop.
由于在波段內(nèi)使用頻段進(jìn)行加密,會(huì)有一定的重碼率,卷簾門遙控器使用的是滾動(dòng)編碼加密方式,如果采用固定的編碼方式,只要10000套卷簾門遙控器就有可能出現(xiàn)重開的現(xiàn)象,及不,因此,現(xiàn)在都采用滾動(dòng)編碼方式。
Due to the use of frequency band encryption in the band, there will be a certain bit repetition rate. Rolling coding encryption method is used for rolling shutter door remote control. If fixed coding method is adopted, as long as 10000 sets of rolling shutter door remote control may reopen, and it is not safe. Therefore, rolling coding method is adopted now.
近幾年,由于使用的需要,且藍(lán)牙具有很好的加密性,已經(jīng)出現(xiàn)了藍(lán)牙控制式的電動(dòng)卷簾門,別看我們個(gè)人的手機(jī)、電腦藍(lán)牙通訊距離只有10米左右,其實(shí),商業(yè)藍(lán)牙的通訊距離可以達(dá)到80——100米的距離,也完全能夠滿足使用。
In recent years, due to the need of using security and the good encryption of Bluetooth, there has been a Bluetooth controlled electric rolling shutter door. Although our personal mobile phones and computers only have a Bluetooth communication distance of about 10 meters, in fact, the communication distance of commercial Bluetooth can reach 80-100 meters, which can fully meet the use.
如果有遠(yuǎn)程控制需求,比如某工廠的特殊材料需要總經(jīng)理或者某人單獨(dú)專門管理,但是此人又有出差的需要,這是就需要庫管和總經(jīng)理雙重管理驗(yàn)證,一般這類管理都需要兩把鑰匙和監(jiān)控條件,此時(shí)就可以設(shè)置遠(yuǎn)程開鎖功能。將開鎖控制接入互聯(lián)網(wǎng),通過手機(jī)APP遠(yuǎn)程開鎖,這時(shí)候就沒有距離限制了,只要在地球上有網(wǎng)絡(luò),任何地方都可以遠(yuǎn)程開鎖。
If there is a need for remote control, for example, the special materials of a factory need to be managed by the general manager or someone, but the person needs to travel, this requires the double management verification of the warehouse keeper and the general manager. Generally, this kind of management requires two keys and monitoring conditions. At this time, the remote unlocking function can be set. Access the unlock control to the Internet, and unlock remotely through mobile app. At this time, there is no distance limit. As long as there is a network on the earth, you can unlock remotely anywhere.
