电动卷帘门多远能控制开关
来源:http://www.jnzxmy.com 日期:2021-03-02 发布人:
当前,电气化时代的卷帘门都是可以遥控的,但是遥控的距离与设备的种类有很大的关联,不同类型的设备种类有不同的控制距离。那么,卷帘门遥控器可以控制多远的距离呢?了解这个问题之前,我们需要先了解无线电信号这个概念。
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.

无线电遥控常用的载波频率为315mHz或者433mHz,遥控器使用的是规定的开放频段,在这一频段内,发射功率小于10mW、覆盖范围小于100m或不超过本单位范围的,可以不必经过“无线电管理委员会”审批而自由使用。也就是说,如果你有需要,可以在本单位的院落内任何一个位置控制卷帘门的开关,如果是公共区域的店铺,就要受到100米的数据限制,超过100米就要经无线电管理委员会审批了。说是审批,即使你有再多的理由也不可能通过,因为一个小小的卷帘门怎么可能有超远距离开关门的需求呢。
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米范围内,一般可以通过选择卷帘门信号接收器和遥控器的功率就可以进行确定和调整。目前,大多数卷帘门的控制距离都是30——50米的距离,这个距离已经完全够用了。当遥控器电池电量不足时,会出现控制距离下降的现象。
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.
由于在波段内使用频段进行加密,会有一定的重码率,卷帘门遥控器使用的是滚动编码加密方式,如果采用固定的编码方式,只要10000套卷帘门遥控器就有可能出现重开的现象,及不,因此,现在都采用滚动编码方式。
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.
近几年,由于使用的需要,且蓝牙具有很好的加密性,已经出现了蓝牙控制式的电动卷帘门,别看我们个人的手机、电脑蓝牙通讯距离只有10米左右,其实,商业蓝牙的通讯距离可以达到80——100米的距离,也完全能够满足使用。
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.
如果有远程控制需求,比如某工厂的特殊材料需要总经理或者某人单独专门管理,但是此人又有出差的需要,这是就需要库管和总经理双重管理验证,一般这类管理都需要两把钥匙和监控条件,此时就可以设置远程开锁功能。将开锁控制接入互联网,通过手机APP远程开锁,这时候就没有距离限制了,只要在地球上有网络,任何地方都可以远程开锁。
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.
