基于单片机的语音识别系统控制晾衣架的设计

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 timeto stay at home during the day.The biggest fear is that the weather has suddenly changed,andpeople can't go back home in time to collect the clothes outside.Aiming at this problem,thisdesign focuses on the research and elaboration of various aspects of the intelligent clothescollection rack system.In the design,DHT11 temperature and humidity sensor plays animportant role used to collect the changes of the external environment with the photosensitiveresistance,and the collected signal is transmitted to the single chip microcomputer coreSTC89C52 of the collection system to determine whether it rains or because of the changes ofthe light intensity,Automatic collection of clothes.When the light in the external environmentdarkens to the setting value of photoresist,the system will react according to the collectedinformation and automatically retract the clothes hanger.The owner doesn't have to worryabout late night off work,which leads to the failure to collect the clothes at home in time,andcauses the clothes to be stained with dew at night.The processing system will automaticallysend a pulse signal to the motor to make the motor operate,and automatically retract thehanger.In this moment,the voice module is used to identify and control the shrinkage andextension of hanger.Key words:intelligent STC89C52 DHT11 speech recognition
