卷帘门的原理是如何进行工作的？

1、 Security system

关于卷帘门的原理，其中卷帘门的安全系统主要是红外线电眼开关，安全气压传感器（部份机械精度高控制系统稳定性高的企业使用安全接触带）或光幕系统；光幕系统应该是安全保护的别。升降速度：0.8m/s-1.5m/s，从底到顶一般在2秒钟左右（速度是电动卷闸门的20倍），车辆、行人无需等待，不构成障碍，更高速的是，国外艾富来，巴士德，霍曼，奥泊尼等公司的快速门可以控制到2.5米/秒以上。

Regarding the principle of rolling shutter doors, the safety system of rolling shutter doors mainly includes infrared electric eye switches, safety air pressure sensors (some enterprises with high mechanical accuracy and high control system stability use safety contact belts) or light curtain systems; The light curtain system should be a safety protection system. Lifting speed: 0.8m/s-1.5m/s, usually takes about 2 seconds from bottom to top (20 times the speed of an electric roller shutter). Vehicles and pedestrians do not need to wait and do not form obstacles. Moreover, the fast doors of foreign companies such as Aifulai, Busde, Hohmann, and Opponi can be controlled to above 2.5 meters per second.

二、门布材质

2、 Door fabric material

关于卷帘门的门布材质，通常是以PVC或PVDF膜材作为帘布，是PVDF膜材抗老化性能更好，不易退色而且有自洁功能，做快速卷门适合。产地以德国产或法国产的为。厚度0.8mm-2.0mm。2.0mm厚的门片，会将整个产品结构改变。颜色有橙色、、蓝色、银色、透明网格，黑色等，以橙色为，原因是橙色醒目，刺激昆虫的感观，具有一定的防虫功能。

As for the door fabric of rolling shutter, PVC or PVDF film is usually used as the cord fabric. PVDF film has better anti-aging performance, is not easy to fade, and has self-cleaning function. It is suitable for fast rolling shutter. The place of origin is made in Germany or France. Thickness: 0.8mm-2.0mm. A 2.0mm thick door panel will alter the entire product structure. The colors include orange, blue, silver, transparent grid, black, etc., with orange as the main color. The reason is that orange is eye-catching, stimulates the perception of insects, and has a certain degree of insect prevention function.

三、驱动电机

3、 Drive motor

快速卷帘门和其他卷帘门不同，它用的都是制动减速电机，要求制动快且噪音小。一般市场上卖的制动电机要么制动效果不好要么制动噪音很大，都不太适合用于快速卷门。速比1:10-1:15比较合适。现在也有一种新型的工业快速门电机出现，叫工业快速门专用伺服，这是全新的一种控制*，运行停止时是不需要靠制动器来刹车的，噪音进一步降低。

The fast rolling shutter door is different from other rolling shutter doors in that it uses a braking deceleration motor, which requires fast braking and low noise. The brake motors sold in the general market either have poor braking effect or loud braking noise, which are not suitable for fast rolling doors. A speed ratio of 1:10 to 1:15 is more suitable. There is now a new type of industrial fast door motor called industrial fast door dedicated servo, which is a new type of control *. When running and stopping, there is no need to rely on the brake to brake, and the noise is further reduced.

四、工作过程

4、 Work process

关于卷帘门的工作过程，它是由开门传感器提供触发信号给控制系统，控制系统根据快速卷门的当前位置发出指令给变频器，启动驱动电机使门帘快速上升，车辆行人通过后门帘自动下降，关闭通道，直到下一个开门信号再次打开。顾名思义，快速卷门升降速度快，不能像钢制卷闸门一样直接启动停止，一般需要变频器来控制电机的转速。上升时越快越好，快到位时（20cm左右）需要有一个减速缓冲停止过程，以防止撞击轨道，防止夹人，降低噪音，这也是衡量快速卷门性能好坏的一个标准。

Regarding the working process of the rolling shutter door, we will focus on introducing it below. It is triggered by the door opening sensor to the control system, which sends instructions to the frequency converter based on the current position of the fast rolling shutter. The control system starts the driving motor to quickly raise the door curtain. After the vehicle and pedestrian pass through, the door curtain will automatically descend and close the channel until the next door opening signal opens again. As the name suggests, the fast rolling door has a fast lifting speed and cannot be directly started or stopped like a steel rolling door. Generally, a frequency converter is needed to control the motor speed. The faster the ascent, the better. When it reaches the desired position (around 20cm), there needs to be a deceleration buffer stop process to prevent collision with the track, prevent jamming, and reduce noise. This is also a standard for measuring the performance of fast rolling doors.
