對于使用相對頻繁的電動卷簾門來說，電控系統的限位準確性和保護是重要的兩個方面。今天濟南卷簾門廠家就一次性將這些問題說個清楚。

For the electric roller shutter doors which are used frequently, the accuracy of limit and safety protection of the electric control system are two important aspects. Today, the manufacturer of Jinan roller shutter door explained these problems at one time.

限位準確

Accurate limit

一樘電動卷簾門，電機應該在門開到什么位置的時候停，不停會怎樣？門關到什么位置停，不停又會怎樣？

For an electric rolling shutter door, the motor should stop when the door is opened to what position. What will happen if the motor does not stop? Where does the door close and stop?

電動卷簾門是在電機帶動下將簾板卷繞在門軸上，如果門開到高位置，電機沒有及時停住，就會將簾板從門框中強制甩出，繼而發生墜落傷人危險。

The electric rolling shutter door is driven by the motor to wind the shutter on the door shaft. If the door is opened to a high position and the motor does not stop in time, the shutter will be forced out of the door frame, and then fall and hurt people.

如果門關到低位置（地面），電機沒有立即停住，而是繼續帶動簾板向下，簾板則會逐級向下擠壓，導致門板變形，久而久之將無法正常關門。如下圖這樘門。

If the door is closed to the low position (ground), the motor does not stop immediately, but continues to drive the shutter downward, and the shutter will be squeezed downward step by step, resulting in deformation of the door panel, and it will be unable to close the door normally over time. The door is as shown in the figure below.

卷簾門電控系統配備的數字式編碼器，在安裝時可自動進行門簾啟停位置學習，位置精準，長時間使用后也不會跑偏，確保卷簾門啟閉正常。

The electric control system of the roller shutter is equipped with a professional digital encoder, which can automatically learn the starting and stopping positions of the shutter during installation. The position is accurate, and it will not deviate after a long time of use, so as to ensure the normal opening and closing of the roller shutter.

保護

safeguard

除此之外，卷簾門的性也不容忽視，比如門簾墜落的問題，卷人、壓人的問題等等，近年來時常見諸于報端。

In addition, the safety of rolling shutter doors can not be ignored, such as the problems of falling curtains, rolling people, pressing people, etc., which are common in the newspapers in recent years.

卷簾門內置扭矩保護裝置，無論何種原因引起的扭矩異常，電機都能自動觸發并鎖住門軸，防止門簾墜落。

The rolling shutter door is equipped with a built-in torque protection device. No matter what causes abnormal torque, the motor can automatically trigger and lock the door shaft to prevent the curtain from falling.

一些事故都是卷簾門在開啟和關閉過程中，電控系統沒有檢測到門簾下方的人員所導致。特別是一些民用場所，由于門本身不大，容易引起兒童的好奇心，在開門時攀爬玩耍而導致事故。針對此類危險，卷簾門在保障通行方面設置了層層保護：

Some accidents are caused by the failure of the electric control system to detect the personnel under the curtain during the opening and closing of the rolling shutter door. Especially in some civil places, because the door itself is not large, it is easy to arouse children's curiosity and cause accidents when they climb and play when opening the door. In view of this kind of danger, roller shutter doors are provided with layers of protection to ensure traffic safety:

一、開/關門力保護功能。當有人員或車輛在關門路徑上停留時，電機檢測到阻力即刻停止關門。同樣，當門開啟時，如有人扒住門簾，電機將檢測到門簾重量異常，停止開啟動作。

1、 Opening/closing force protection function. When a person or vehicle stops on the door closing path, the motor will stop closing the door immediately when it detects resistance. Similarly, when the door is opened, if someone grabs the curtain, the motor will detect that the curtain weight is abnormal and stop opening.

二、底部光電保護功能。對于大尺寸的工業卷簾門，配備底部光電保護裝置，在與地面接觸的橡膠軟底邊內置紅外光眼，關門時觸碰到障礙物，將觸發光眼保護，電機隨即停止關門動作，防止危險的發生。

2、 Photoelectric protection function at the bottom. For large-sized industrial roller shutter doors, the bottom photoelectric protection device is equipped. An infrared optical eye is built in the rubber soft bottom that contacts the ground. When the door is closed, the optical eye protection will be triggered when the obstacle is touched, and the motor will stop closing the door immediately to prevent the occurrence of danger.
