1、 Security system

關于卷簾門的原理，其中卷簾門的系統主要是紅外線電眼開關，氣壓傳感器（部份機械精度高控制系統穩(wěn)定性高的企業(yè)使用接觸帶）或光幕系統；光幕系統應該是保護的別。升降速度：0.8m/s-1.5m/s，從底到頂一般在2秒鐘左右（速度是電動卷閘門的20倍），車輛、行人無需等待，不構成障礙，更高速的是，國外艾富來，巴士德，霍曼，奧泊尼等公司的快速門可以控制到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、門布材質

2、 Door fabric material

關于卷簾門的門布材質，通常是以PVC或PVDF膜材作為簾布，是PVDF膜材抗老化性能更好，不易退色而且有自潔功能，做快速卷門適合。產地以德國產或法國產的為。厚度0.8mm-2.0mm。2.0mm厚的門片，會將整個產品結構改變。顏色有橙色、、藍色、銀色、透明網格，黑色等，以橙色為，原因是橙色醒目，刺激昆蟲的感觀，具有一定的防蟲功能。

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、驅動電機

3、 Drive motor

快速卷簾門和其他卷簾門不同，它用的都是制動減速電機，要求制動快且噪音小。一般市場上賣的制動電機要么制動效果不好要么制動噪音很大，都不太適合用于快速卷門。速比1:10-1:15比較合適?，F在也有一種新型的工業(yè)快速門電機出現，叫工業(yè)快速門專用伺服，這是全新的一種控制*，運行停止時是不需要靠制動器來剎車的，噪音進一步降低。

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、工作過程

4、 Work process

關于卷簾門的工作過程，它是由開門傳感器提供觸發(fā)信號給控制系統，控制系統根據快速卷門的當前位置發(fā)出指令給變頻器，啟動驅動電機使門簾快速上升，車輛行人通過后門簾自動下降，關閉通道，直到下一個開門信號再次打開。顧名思義，快速卷門升降速度快，不能像鋼制卷閘門一樣直接啟動停止，一般需要變頻器來控制電機的轉速。上升時越快越好，快到位時（20cm左右）需要有一個減速緩沖停止過程，以防止撞擊軌道，防止夾人，降低噪音，這也是衡量快速卷門性能好壞的一個標準。

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.
