电动卷帘门出现远距离操作故障的原因主要有下面的几点：

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

1、高度：济南卷帘门电动遥控操作仪器的天线越高，遥控距离越远，但受客观条件限制;

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、发射功率：遥控操作仪器的发射功率大则距离远，但耗电大，容易产生干扰;

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、接收灵敏度：遥控接收器的接收灵敏度提高，遥控距离增大，但接收的灵敏度就会很容易受干扰造成误动或失控;

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、天线：若是采用的是直线型天线，并且相互平行，这样能够获得的遥控距离比较远，但会出现占据空间大，在使用中把天线拉长、拉直可增加遥控距离;

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、阻挡：目前使用的无线遥控器使用规定的UHF频段，其传播特性和光近似，直线传播，绕射较小，发射器和接收器之间如有墙壁阻挡将大大打折遥控距离。

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.

如果是钢筋混泥土的墙壁，由于导体对电波的吸收作用，影响更甚。所以若是选择这种类型的遥控操作仪器的话，那么在远距离操作的时候出现故障的可能性会随着距离的增加额增大的。

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.
