摘 要

随着改革开放的逐步推进,国家发展繁荣昌盛,经济实力稳步提升,人民物质生活水平也在不断改善。为了适应人民群众日益增加的美好生活要求,各类不同形式的商品和日常生活必备用品越来越广泛。随之而来的就是日益增加的生活垃圾,给其他地区的生态环境带来了极大的威胁,有些地区的城市也已出现了垃圾包围的现象。当前,垃圾分类已成为我国需要解决的一个棘手问题。但是仍然有很多人不了解垃圾如何分类,难以做出正确的选择。因此,利用先进的计算机技术和嵌入式设备,采用方便合理的方式,对家中的垃圾桶进行智能化处理,是个十分有实用价值值得深入研究的课题。

本课题主要设计基于语音识别的智能垃圾桶,以Arduino单片机为主控芯片,通过语音识别传感器检测用户语音如“苹果”,“废纸”等,当匹配成功时,可以对垃圾进行分类的判断,然后自动判断出该垃圾的种类,比如厨余垃圾,其他垃圾,可回收垃圾,有害垃圾,打开相对应的垃圾桶,提示用户正确垃圾分类。该设计成本低,有性能稳定、能全天候工作、耗电省的特点,具有很大的实用性。

Intelligent Trash Bin Based on Voice Recognition

Abstract

With the gradual progress of reform and opening up, the country is developing and prospering, the economic strength is steadily improving, and the people's material living standard is also improving. In order to meet the increasing demands of the people for a better life, various types of commodities and daily necessities are becoming more and more extensive. What follows is the increasing amount of domestic garbage, which has brought a great threat to the ecological environment of other regions, and cities in some regions have also been surrounded by garbage. At present, garbage classification has become a thorny problem that needs to be solved in our country. But there are still many people who do not know how to classify garbage, and it is difficult to make a correct choice. Therefore, the use of advanced computer technology and embedded equipment, the use of convenient and reasonable way, the garbage can in the home for intelligent treatment, is a very practical value worthy of research topics.

This topic mainly design intelligent trash can, based on speech recognition with the single chip processor as the master control chip, through voice recognition sensors user voice such as "apple", "waste paper" and so on, when the match is successful, can classify rubbish judgment, then automatically determine the types of the rubbish, such as kitchen waste, other waste, toxic waste, recycling waste, Open the corresponding garbage can and prompt the user to correctly classify garbage. The design has the characteristics of low cost, stable performance, all-weather operation and power saving, and has great practicability.

1.1智能垃圾桶设计的选题背景和意义

新中国成立以后我国社会飞速发展,国家的经济水平也在不断提升,但是与之而来的是日益严重的环境问题,老百姓的生活开始出现许多不同种类的污染,土地污染,水资源污染,空气污染等等,而我们日常生活中产生的各种垃圾就是造成这些污染问题的元凶,我们的环境和资源被它们所压榨,而且给我们的日常生活造成了极大的困扰。

不仅如此,这些垃圾还对地球外部的生态环境造成伤害,这不单单减少了动植物的生存空间,更是极大的打破了生物圈的稳态,并且污染地表的环境。部分垃圾如果没有经过有效合理的安排,甚至可能会影响动植物,后续可能还会对我们赖以生存的环境造成损害。更严重的是,垃圾中微生物的滋生可能会对人体会造成很大的威胁,为病菌、病毒、害虫等滋生提供条件,危害人体身健康,导致各类疾病的传播。
