电动卷帘门多远能控制开关
目今，电气化时代的卷帘门都是可以�？氐�，可是�？氐木嗬胗肷璞傅闹掷嘤泻艽蟮墓亓�，差别类型的设备种类有差别的控制距离。那么，卷帘门�？仄骺梢钥刂贫嘣兜木嗬肽�？了解这个问题之前，我们需要先了解无线电信号这个看法。
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�？爻Ｓ玫脑夭ㄆ德饰�315mHz或者433mHz，�？仄魇褂玫氖腔ǖ目牌刀�，在这一频段内，发射功率小于10mW、笼罩规模小于100m或不凌驾本单位规模的，可以不必经过“无线电治理委员会”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肆，就要受到100米的数据限制，凌驾100米就要经无线电治理委员会审批了。说是审批，纵然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米规模内，一般可以通过选择卷帘门信号接收器和�？仄鞯墓β示涂梢越腥范ê偷鹘�。目前，大大都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�？仄鞯绯氐缌咳狈κ�，会泛起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�？仄魇褂玫氖亲嗦爰用芊椒�，如果接纳牢固的编码方法，只要10000套卷帘门�？仄骶陀锌赡芊浩鹬乜南窒�，及不，因此，现在都接纳转动编码方法。
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，已经泛起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抵达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，好比某工厂的特殊质料需要总经理或者某人单独专门治理，可是此人又有出差的需要，这是就需要库管和总经理双重治理验证，一般这类治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效。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.
