资 源 简 介

采用NE555定时器设计一种自动晾衣杆控制电路,其利用光传感器或温度传感器将天气变化的状态输入NE555内,通过NE555内部的单稳态触发器动作来控制电动机的正转(即上升)或反转(下降);利用光敏三极管将光照强度控制输入,从而控制三极管的导通或截止,以此来驱动外部机械装置,实现收衣服和晾衣服的功能。该自动晾衣杆的电路设计具有成本低、反应快、能耗小、寿命长、可靠性好等特点。

A control circuit of automatic clothes-aired pole was designed by adopting NE555 timer. The state of weather changes is input into NE555 by opto-sensor or temperature sensor. The foreward rotation(up) or reversion rotation(down)of the motor is controlled by the action of monostable trigger inside the NE555. The input is controlled by illumination intensity of the phototriode,and so the breakover or cut-off of the triode is controlled for driving the external mechanical device and achieve the functions of clothes collection or clothes hanging. The circuit design of this automatic clothes-aired pole has the characteristics of low cost,quick reaction,low energy consumption,long lifetime and high reliability.
