基于智能语音识别控制技术的垃圾分类系统设计与实现.docx

摘 要

随着中国社会的不断发展，中国环境污染问题日益严重，生活垃圾

随着人口的增长越发增加。如今人们对生活环境逐渐重视起来，国家也

开始深度倡导垃圾分类，进行垃圾的回收利用，但由于群众对于垃圾分

类的认识度普遍不高，难以实现大范围垃圾分类规范化的目标；本设计

主要分为硬件设计和软件设计。硬件部分将用到 STM32F103 微处理器模

块、LD3320 语音识别模块、JQ8900 语音输出模块、舵机。主要是采用语

此次设计可以广泛运用于大城市的家庭当中，能有效缓解大城市中

垃圾分类处理能力和人们垃圾分类知识不相匹配的矛盾，日常家庭使用

十分便利，还可以有垃圾分类的教育学习效果。这对提升国民垃圾常识

有极大的帮助，更能为国家文明卫生城市的建设出一份力，同时在市场

上有较好的前景。

Abstract

With the continuous development of Chinese society, the problem of

environmental pollution in China is becoming more and more serious.

Nowadays, people pay more and more attention to the living environment,

and the country has started to advocate garbage classification and recycling.

However, because the general public has a low awareness of garbage

classification, it is difficult to achieve the goal of standardizing large-scale

garbage classification. Designed for hardware and software. The hardware

the operation of voice-to-text and keyword comparison is used to identify the

junk name provided by the user. What kind of garbage it belongs to. The

software part mainly controls the driving of the trash can switch, voice

matching processing, and interactive audio output, thereby completing the

voice control function of the intelligent voice trash can with

human-computer interaction, and the call can be answered.

The design can be widely applied to families in big cities and

effectively alleviate the contradiction between the garbage classification and
