電動卷簾門出現遠距離操作故障的原因主要有下面的幾點：

The main reasons for remote operation failure of electric roller shutter doors are as follows:

1、高度：濟南卷簾門電動遙控操作儀器的天線越高，遙控距離越遠，但受客觀條件限制;

1. Height: The higher the antenna of the Jinan roller shutter door electric remote control operation instrument, the farther the remote control distance, but subject to objective conditions;

2、發射功率：遙控操作儀器的發射功率大則距離遠，但耗電大，容易產生干擾;

2. Transmission power: The transmission power of remote control instruments is large and can be far away, but it consumes a lot of power and is prone to interference;

3、接收靈敏度：遙控接收器的接收靈敏度提高，遙控距離增大，但接收的靈敏度就會很容易受干擾造成誤動或失控;

3. Receiving sensitivity: The receiving sensitivity of the remote control receiver increases, and the remote control distance increases, but the receiving sensitivity is easily affected by interference, causing misoperation or loss of control;

4、天線：若是采用的是直線型天線，并且相互平行，這樣能夠獲得的遙控距離比較遠，但會出現占據空間大，在使用中把天線拉長、拉直可增加遙控距離;

4. Antenna: If a linear antenna is used and is parallel to each other, the remote control distance can be relatively long, but it will occupy a large space. Lengthening or straightening the antenna during use can increase the remote control distance;

5、阻擋：目前使用的無線遙控器使用規定的UHF頻段，其傳播特性和光近似，直線傳播，繞射較小，發射器和接收器之間如有墻壁阻擋將大大打折遙控距離。

5. Blocking: The wireless remote control currently used uses the specified UHF frequency band, with propagation characteristics similar to light, linear propagation, and small diffraction. If there is wall blocking between the transmitter and receiver, it will greatly reduce the remote control distance.

如果是鋼筋混泥土的墻壁，由于導體對電波的吸收作用，影響更甚。所以若是選擇這種類型的遙控操作儀器的話，那么在遠距離操作的時候出現故障的可能性會隨著距離的增加額增大的。

If it is a reinforced concrete wall, the impact will be even worse due to the absorption of electric waves by the conductor. So if you choose this type of remote control instrument, the possibility of malfunctions during remote operation will increase with the increase of distance.
