1、银行卷帘门的主控制器是自动门的指挥中心，通过内部编有的指令程序的大规模集成块，发出相应指令，指挥马达或电锁类系统工作。同时人在通过时主控器调节门扇开启的速度、开启幅度等参数。
1. The main controller of the bank curtain door is the command center of the automatic door. Through the large-scale integrated block of the internal instruction program, it sends out the corresponding instructions to direct the motor or electric lock system. At the same time, the main controller adjusts the opening speed, opening range and other parameters of the door.
2、感应探测器是负责采集外部信号，当有移动物体进入它的范围时，它就给主控制器一个信号，它如同人的眼睛。
2. The induction detector is responsible for collecting external signals. When a moving object enters its range, it gives a signal to the main controller, which is like human eyes.
3、动力马达能提供主动地开关门，能控制门扇的加速与减速运行。
3. The power motor can actively open and close the door and control the acceleration and deceleration of the door.
4、门扇行进轨道能约束门扇的吊具走轮系统，使其按特定的方向行进。
4. The traveling track of the door fan can restrict the traveling wheel system of the lifting gear of the door fan and make it travel in a specific direction.
5、门扇吊具走轮系统是用于吊挂活动门扇的，同时在动力的牵引下来带动门扇运行。
5. The door-fan spreader wheel system is used to hang the movable door-fan, at the same time, it drives the door-fan to run under the traction of power.
6、同步皮带或三角皮带，它们用于传输马达所产生的动力，牵引着门扇吊具走轮系统。
6. Synchronized belts or triangular belts, which are used to transmit the power generated by the motor and to tract the door-fan suspension traveling wheel system.
7、下部导向系统是门扇下部导向与定位的装置，防止门扇在运行时出现前后门体摆动。
7. The lower guiding system is a device for guiding and positioning the lower part of the door, which prevents the front and rear door body from swinging during the operation of the door.
