智能晾衣架的设计与实现

摘要

社会在一天天发展进步，智能产品在我们的家庭生活中出现的频率也日益增多，给人们的日常生活带来了便利。然而，洗涤工具仍处于相对原始的水平变化不大，正在逐渐脱离我们的生活。对现在城市里的大多数人来说，他们每天忙于工作，白天很少呆在家里，所以当天气突然变了，他们不能及时把衣服拿回来。针对这一问题，本文研究了将DHT11温湿度传感器和光敏电阻采集的信号传输到核心单片机AT89S52的智能晾衣架系统。根据实时的温度、湿度和光强，判断衣物烘干架是否应该收回。

当空气中的相对湿度超过设置值(认为会下雨或已经下雨)或光明变成黑暗一定值(认为已经进入黑天),该系统将发出报警,提醒业主收集衣服并延迟时间。无响应后，系统自动向电机发送脉冲信号，从而控制机械部分自动取回衣架。

Abstract

With the continuous development and progress of the society, intelligent products are constantly pouring into our family life, bringing convenience to people's daily life. However, the washing tools are still not changing at a relatively primitive level and are gradually getting out of our lives. For most people in the city today, they are busy with work every day and rarely stay at home during the day, so when the weather suddenly changes, they can't get their clothes back in time. In response to this problem, this paper studies the intelligent drying rack system that transmits the signal collected by DHT11 temperature and humidity sensor and photoresistor to the core single chip AT89S52. According to the temperature, humidity and light intensity at that time, it is judged whether the clothes drying rack should be retracted.

When the relative humidity in the air exceeds the set value (it thinks it will rain or has rained) or the light becomes dark (assuming it has entered the black sky), the system will issue an alarm to remind the owner to collect clothes and delay the time. After no response, the system automatically sends a pulse signal to the motor to control the mechanical part to automatically retrieve the hanger.
