用专用电机带动卷帘中心轴转动，达到卷帘开关，当转动到电机设定的上下限位时自动停止。

Use a dedicated motor to drive the central axis of the roller shutter to rotate, reaching the roller shutter switch. When it reaches the upper and lower limits set by the motor, it automatically stops.

卷闸门专用电机有：外挂卷门机、澳式卷门机、管状卷门机、防火卷门机、无机双帘卷门机、快速卷门机等。

The special motors for rolling gates include: external rolling door machine, Australian rolling door machine, tubular rolling door machine, fire rolling door machine, inorganic double curtain rolling door machine, fast rolling door machine, etc.

A、智能红外线防爬装置：遇人爬门时,系统会马上报警,从而保障门内的。

A. Intelligent infrared anti climbing device: When someone climbs the door, the system will immediately sound an alarm to ensure safety inside the door.

B、特种型材：在高硬度锌铝合金型材上加上不同几何形状筋骨能大大增强其强度，表面经特殊电泳处理，光泽无限，不易粘尘，不被污染气体腐蚀，决不生锈，保新期长。

B. Special profiles: Adding different geometric shapes of ribs to high hardness zinc aluminum alloy profiles can greatly enhance their strength. The surface is treated with special electrophoretic treatment, which has infinite luster, is not easy to stick to dust, is not corroded by polluted gases, never rusts, and has a long shelf life.

C、工程塑料：门体主要塑料件（如管材与管材间的连接，塑料件，门体活动部件等等）采用高质量工程塑料（如PC、PA），韧性高，耐冲击,抗扭曲，耐磨，耐冻，耐晒，不易老化，使用寿命长，免受风雪雷电、日晒雨淋之苦。

C. Engineering plastics: The main plastic components of the door body (such as the connection between pipes, plastic parts, door moving parts, etc.) are made of high-quality engineering plastics (such as PC, PA), which have high toughness, impact resistance, torsion resistance, wear resistance, frost resistance, sun resistance, not easy to age, long service life, and are free from wind, snow, lightning, sun, and rain.

D、智能红外线探头防碰撞装置：门体在关闭过程中遇人或异物30-50cm可自动返回运行，从而保障车辆及行人 的。 标准结构:门排内空（即前后相临两大弯主管之间的距离，不含主管尺寸）采用卷闸门标准尺寸320mm（参照国外技术），保证交叉管固，并大大减少运行噪音。

D. Intelligent infrared probe anti-collision device: The door body can automatically return to operation when encountering people or foreign objects 30-50cm during the closing process, thereby ensuring the safety of vehicles and pedestrians. Standard structure: The inner space of the gate (i.e. the distance between the two adjacent large curved main pipes, excluding the main pipe size) adopts the standard size of a rolling gate of 320mm (referring to foreign technology) to ensure the most solid cross pipe and greatly reduce operating noise.
