快速卷帘门是由电机转动带动门帘上下移动达到开门关门的，而电机是由独立的控制系统来控制的，门的开门高度，关门高度已经开关门的速度都是可以根据需求设置的，快速卷帘门也是属于自动化设备中的一员。

The fast rolling shutter door is driven by a motor to move up and down to open and close the door. The motor is controlled by an independent control system, and the opening height, closing height, and opening and closing speed of the door can be set according to needs. The fast rolling shutter door is also a member of the automation equipment.

当然，长期使用中不可避免会有一些故障的出现，出现故障怎么办，不要着急，今天就跟大家说一下常见的门帘卡着不能动了该怎么处理。

Of course, there will inevitably be some malfunctions during long-term use. What to do if there are malfunctions? Don't worry. Today, I will talk to you about how to deal with common cases of door curtains getting stuck and not moving.

出现这种情况一般是有两个原因，带有雷达感应自动开门的客人要先检查门头上方的雷达感应器，看雷达是否感应到了门旁边的其他物体，因为雷达是感应一切移动的物体只要是动态的，都能使门打开，同理感应器如果遇到碰撞感应到了周边的其他物体门也会是一直处于打开的状态。

There are generally two reasons for this situation. Guests with radar sensing automatic door opening should first check the radar sensor above the door head to see if the radar has detected other objects next to the door, because the radar senses all moving objects, as long as they are dynamic, it can open the door. Similarly, if the sensor detects other objects in the surrounding area during a collision, the door will remain open.

二是检查两侧门柱离地面30公分左右的光电，光电是一个对射的保护装置，两侧柱子上一边是发射器，一边是反光板，发射出来的红外光线通过对面的反光板折射回来，中间没有物体切地对射的光线门就正常使用，可是一旦门体下方有物体或人阻断了光线，门帘就会停留在上方不下来。光电亮绿灯是正常的，亮红灯就是故障或者有人、物遮挡了对射光线，或者是光电被碰撞，发射出来的红外光线没有射到对面的反光板上，二是射在门旁边其他物体上，这种情况下门也是不会降落的。

The second step is to check the safety photoelectric devices on both sides of the door pillars, which are about 30 centimeters above the ground. The photoelectric devices are a protective safety device that targets the ground. One side of the pillars is a transmitter, and the other side is a reflector. The emitted infrared light is refracted back through the opposite reflector. If there is no object in the middle that targets the ground, the door can be used normally. However, if there is an object or person blocking the light below the door body, the door curtain will stay above and not come down. It is normal for the photoelectric light to light up green, while a red light indicates a malfunction or obstruction of the opposing light by someone or object, or a collision with the safety photoelectric light, causing the emitted infrared light to not reach the opposite reflector. Secondly, if it hits other objects next to the door, the door will not land.
