北京理工大学珠海学院 2016 届本科生毕业设计 基于单片机的语音识别系统控制晾衣架的设计 摘 要在生活中的大多数人每天都要为了工作而奔波, 白天几乎没有空闲的时间留在家里。最怕的就是天气突然发生了变化, 人们不能及时的回到家中把晾晒在外面的衣服收取回来。本设计就是针对这一问题, 重点的研究和阐述关于智能收衣架系统的各个方面 在设计中运用了 DHT11 温度湿度传感器, 跟光敏电阻对外界环境变化进行采集，然后收集到的数据据会被发送到 STC89C52 单片机 ，确定是否下雨、或者因为光照强度的变化, 自动的收取回衣物。而当外界环境中光线变暗到光敏电阻的设定的值时, 系统将会根据采集到的信息作出反应并并自动伸缩收回晾衣架。主人不用担心晚上过晚下班的时候导致无法及时回家收取衣物，而使衣物沾染到晚间露水,处理系统将会自动向电机发送脉冲信号, 使电机运作，并自动收回衣架。本次利用语音模块进行识别控制衣架收缩和放出。关键词：智能 STC89C52 DHT11 语音识别北京理工大学珠海学院 2016 届本科生毕业设计AbstractMost people in our life have to rush for work every day, and there is almost no free time to stay at home during the day. The biggest fear is that the weather has suddenly changed, and people can't go back home in time to collect the clothes outside. Aiming at this problem, this design focuses on the research and elaboration of various aspects of the intelligent clothes collection rack system. In the design, DHT11 temperature and humidity sensor plays an important role used to collect the changes of the external environment with the photosensitive resistance, and the collected signal is transmitted to the single chip microcomputer core STC89C52 of the collection system to determine whether it rains or because of the changes of the light intensity, Automatic collection of clothes. When the light in the external environment darkens to the setting value of photoresist, the system will react according to the collected information and automatically...
