下辈子做迩的新娘 09-04 02:55

工作原理电源变压器B、桥式整流堆和电容C1组成12V直流电源。继电器J1、J2和行程开关K1、K2组成互锁电源极性切换电路。当按下按钮QA时,220V交流电接通,指示灯L点亮,由于C2的存在,J1两端的电压不能突变,故J2优先吸合,J2-1闭合,电路自保,J2-2断开,电路互锁,J2-3、J2-4闭合,电机得电正转,窗帘开启。窗帘完全开启后,行程开关K2被拉线拉动而断开,J2失电释放,J2-1

一、控制窗帘开、闭的智能控制器系统。二、操作和设置主控制器的无线控器。【电动窗帘】三、拉动窗帘的执行机构―电机和拉动机构。主机控制电机的正、反转动,通过滑轮拉动窗帘自动闭合或者打开。也可以使红外遥控器可以直接遥控窗帘的开闭,用遥控器对主控制器进行自动功能的设置,一旦设置并开启自动控制功能,主控制器将按设定功能自动完成控制。主控制器是本控制系统中的关键部分。

智能电动可以根据外界光照强度的变化实现窗帘的张开与关闭,即早上拉开窗帘,晚上关闭窗帘,也可以认为操控窗帘,给人营造温馨与舒适的环境。窗帘位置检测的原理是通过红外传感器,通过51单片机控制来获取窗帘底部所在的位置,进而为单片机控制电机是否工作提供依据。窗帘的拉开与闭合,以及拉开的多少,与外界光照强度关,多个模块共同工作,从而做到智能控制窗帘。

这个很简单的也用不到四千字的也不要设计的图纸就可以的。你搞个1.小的电动机2.正反转的控制电路3.限位开关4.定时器,就OK了。把这些接到一起,控制顺序是利用时间控制器来启动电机正转,到达位置时停掉,再到时间电机反转,到达位置时停。就解决
