Default 卷帘门基本原理是什么

1、感应探测器:负责采集外部信号,如同人们的眼睛,当有移动的物体进入它的工作范围时,它就给主控制器一 个脉冲信号;
2、动力马达:提供开门与关门的主动力,
3、主控制器:它是自动门的指挥中心,通过内部编有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;同时人们通过主控器调节门扇开启速度、开启幅度等参数。控制门扇加速与减速运行。
4、门扇行进轨道:就象火车的铁轨,约束门扇的吊具走轮系统,使其按特定方向行进。
5、门扇吊具走轮系统:用于吊挂活动门扇,同时在动力牵引下带动门扇运行。
6、同步皮带(有的厂家使用三角皮带):用于传输马达所产动力,牵引门扇吊具走轮系统。
7、下部导向系统:是门扇下部的导向与定位装置,防止门扇在运行时出现前后门体摆动。
当门扇要完成一次开门与关门,其工作流程如下:
感应探测器探测到有人进入时,将脉冲信号传给主控器,主控器判断后通知马达运行,同时监控马达转数,以便通 知马达在一定时候加力和进入慢行运行。马达得到一定运行电流后做正向运行,将动力传给同步带,再由同步带将 动力传给吊具系统使门扇开启;门扇开启后由控制器作出判断,如需关门,通知马达作反向运动,关 闭门扇。
