城市生活垃圾分类自动提醒与查询装置设计

Design of Automatic Reminder and Inquiry Device for Classification of Municipal SolidWaste

针对老人、小孩等部分人群对垃圾分类方法不太容易分清的问题,提出了一套基于人体感应和语音提示的城市生活垃圾分类自动提醒与查询装置。系统主要由STM32单片机核心控制系统、LD3320语音识别模块、人体感应模块、语音播报模块以及TFT显示屏等部分构成。通过在系统内集成语音词库和匹配算法实现对垃圾自动分类提示,并在对应的垃圾投入口设置声光提示。经过对垃圾词条测试,基本能够实现对日常生活垃圾进行自动分类并提醒。

In order to solve the problem that the old people and children are not easy to distinguish the garbage classification method,this paper presents a set of automatic reminder and inquiry device based on human body induction and voice prompt.The system is mainly composed of STM32 mcu core control system,LD3320 speech recognition module,human body induction module,speech broadcast module and TFT display screen.The automatic garbage classification prompt is realized by integrating speech word base and matching algorithm in the system,and the acousto-optic prompt is set at the corresponding garbage input port.Through the garbage entry test,the functions of garbage classification and automatic reminder are achieved.
