文档介绍：摘要
随着社会的不断发展和进步,智能化的产品在不段的涌入我们的家庭生活,给我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,已经跟不上我们生活的节奏的变化,对于现在城市里的大多数人们每天都是忙于工作,白天的时间几乎都不在家中。当天气变化时不能及时的把衣服收回。关于这个问题本文对智能晾衣架系统进行研究,运用DS18B20温度传感器、CHR01湿度传感器和5547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步进电机,从而控制机械部分自动收回晾衣架

ABSTRACT
With the continuous development and advancement of society, many intellectualization products enter into our daily life and give convenience for our life. But the rack used to dry clothe is in a low level and has little change so it can not catch up with the rhythm of our life. The residents in modern cities are always busy in their work and can not stay at home during the daytime. When weather goes bad they have no chance to take back their clothes. Based on this problem this paper designs this intellectualized rack used to dry clothes system. This system uses the signal gathered by DS18B20 temperature sensor, CHR01 humidity sensor and 5547 photoresistance sensor to put into the system processing core monolithic integrated circuit AT89S52. Whether to take back the clothes was determined by the current status of temperature, humidity and sunshine. When the relative humidity surpasses the defined value (There is a tendency to rain or have rained) or the sunshine was dark to a special definite value ( The weather turns dark) the system will send out warning and prompt the master to take back the clothes. If there is nobody replying it, the system will send out pulse signal into step motor automotive, control the mechanical part and take back the rack used to dry clothes.
Key Words:temperature sensor,humidity sensor,photoresistance ,AT89S52.
