基于AT89S52单片机的智能晾衣架控制系统设计
摘要
随着社会的不断发展和进步,智能化的产品在不断的涌入我们的家庭生活,给人们的生活起居带来便利,但是晾衣工具还是处于比较原始的层次几乎没有什么改变,渐渐与我们的生活脱节。对于现在城市里的大多数人们每天忙于工作,白天几乎都不在家中,当天气变化时不能及时将衣物收回。关于这个问题,本文对智能晾衣架系统进行研究,运用DHT11温湿度传感器,光敏电阻采集到的信号传输给系统处理核心单片机AT89S52,根据当时的温湿度和光线的强弱判断晾衣架是否要收回。当空气中的相对湿度超过设定值(认为要下雨或者已经下雨)或光线变暗到一定值(认为已经天黑)时,系统会发出报警提示主人收衣服并延时,无人应答后系统会自动发出脉冲信号给电机,从而控制机械部分自动收回晾衣架。

Abstract
With the constant development and social progress, intelligent products in the continuous influx of our family life, to the people's daily life more convenient, but airing tool or in a primitive level almost no change, gradually and our life away. For now the city where most people are busy with their work every day, hardly ever at home, when weather changes will be unable to recover. About this question, the intelligent clothes hanger system is studied, using the DHT11 temperature and humidity sensor, 5547 photosensitive resistance signals transmitted to the system processing core chip AT89S52, according to the time of the temperature and humidity and light intensity to judge whether to take back the clothes hanger. When the air relative humidity exceeds a set value ( think it's going to rain or rain ) or the dark to a certain value ( that had been dark ), the system will send out alarm host received clothes and delay, no response after the system will automatically send a pulse signal to a stepping motor, so as to control the mechanical parts automatically retract the clothes hanger.
