ABSTRACT
In a society with the rapid development of information, peoples pace of life is getting faster and faster, which also leaves us no extra time to deal with trivial things. For example, the function of drying clothes in fine weather is achieved, and the function of collecting clothes in rainy weather is achieved. At present, the design and rea *51今日免费论文网|www.51jrft.com +Q: *351916072* 
lization of intelligent clothes hanger based on SCM have a very good design idea.
This design is mainly use the element such as rain detection sensor, photosensitive resistance, according to the weather change to collect the clothes washing function, and then transmit the detected results give STC89C5 microcontroller, then single chip microcomputer to the size of the rainfall and the intensity of sunlight to drive the motor to achieve positive rotation or reverse rotation, ultimately through the height of the dryer to implement intelligent washing function, through the use of the FC 37 and LM393 these two modules, realizes the detection of rain and the function of the voltage comparison, for the specific process, after the rain dripping water drops on sensor sensor according to different water droplets size change corresponding resistance, Then, after the voltage comparator conversion, the collected data will be converted into digital quantity and sent to the SCM for judgment, and then the SCM will judge whether to raise the drying rod according to the size of the water drop of the sensor. Under the joint judgment of raindrop sensor and photosensitive resistance, when the single chip microcomputer thinks it is sunny now, it can also determine the best height of washing by light intensity, and then the single chip microcomputer will control the motor corresponding to high and low levels, so as to realize washing and receiving.
Keywords: STC89C52 microcontroller, photosensitive resistor, LM393, raindrop sensor 
绪论
选题背景
在人类发展的进程中经历了第一次工业革命蒸汽机的发明使用、再经过第二次工业革命电的产生，而第三次工业革命则是网络信息技术日益完善的今天，把网络连接到人们的生活家居里面去使用，以前只是在电影里或者书籍上面对家居智能化的产品，有的还要靠想象，但是现在已经成为事实，并且智能家居也悄无声息的慢慢融入我们的生活，这改变了人们的生活方式和工作习惯，同样也一改人们对家具的认识，颠覆了以往对传统家具的认知，家庭里面使用的家具在电子信息技术以及控制技术发展的今天，也可以变得像手机、电视、电脑一样更智能化，这也是智能家居发展的必然趋势。
研究目的
在科技不断发展的今天，人们生活变得越来越忙碌，“朝九晚五”逐渐成为了当代年轻人的标配，所以在晾晒衣服时难免会发生雨天忘记收衣等现象,少则重新清晰，多则衣物掉色。所以就此情况我设计了智能晾衣架，以解决雨天晾衣、收衣难等情况。
