发布时间：2019-01-08 18:16
【摘要】：以LM3S811为核心设计一种智能家居垃圾桶,实现语音控制垃圾桶的运动。以拾音器作为声音传感器,采用延时估计法实现声源方位的实时检测;采用超声波传感器实现了垃圾桶行进的避障功能;同时,采用语音识别技术实现对用户的开启和关闭垃圾桶盖等各种语音指示的识别。关闭垃圾桶盖后,自动回到原来位置。从而达到了垃圾桶"应声而来"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.
