【摘要】:以LM3S811為核心設(shè)計(jì)一種智能家居垃圾桶,實(shí)現(xiàn)語音控制垃圾桶的運(yùn)動(dòng)。以拾音器作為聲音傳感器,采用延時(shí)估計(jì)法實(shí)現(xiàn)聲源方位的實(shí)時(shí)檢測(cè);采用超聲波傳感器實(shí)現(xiàn)了垃圾桶行進(jìn)的避障功能;同時(shí),采用語音識(shí)別技術(shù)實(shí)現(xiàn)對(duì)用戶的開啟和關(guān)閉垃圾桶蓋等各種語音指示的識(shí)別。關(guān)閉垃圾桶蓋后,自動(dòng)回到原來位置。從而達(dá)到了垃圾桶"應(yīng)聲而來"的智能化。
[Abstract]:A kind of intelligent household garbage can is designed with LM3S811 as the core to realize the movement of voice control trash can. The sound pickup is used as the sound sensor and the time-delay estimation method is used to realize the real-time detection of the sound source azimuth, and the ultrasonic sensor is used to realize the obstacle avoidance function of the garbage can. At the same time, the speech recognition technology is used to recognize all kinds of voice indication, such as opening and closing the trash bin lid. After closing the lid of the trash can, automatically return to its original position. In order to achieve the trash can "response to the sound and come" intelligent.
