基于微信小程序的垃圾分类系统的设计与实现

Posted 2022-06-16 weixin_ancenhw

当前的社会科技已经取得了极大的发展和极高的成就，但随之而来逐渐造成了垃圾产出过多的问题。久而久之，这一问题便不断恶化，滋生了一系列新的问题。如垃圾处理问题越来越严峻。伴随着垃圾种类的增多，国家出台了很多政策，如垃圾分类。但由于国民素质水平还不是太高，垃圾分类的概念也知道的不多，很难较好的做到正确的垃圾分类。导致不同种类垃圾过于集中，给垃圾处理的工作带来更大的难题。基于上述缘由，当前可行的办法就是使得垃圾处理具有智能化、自动化、同步化的特点。
本次设计是基于微信小程序设计实现了一个垃圾分类系统。根据垃圾分类现实情况，本人结合系统的概念，结构和基本原理与方法，设计开发出功能完整运行良好的小程序。本设计是基于微信小程序的一套系统，用此来作为前端，后端则使用云开发，实现了识别垃圾分类的基本功能。本系统主要包括两个模块，用户可以通过文字搜索或者扫描识别图片功能进行垃圾分类；管理员可以在云开发中进行系统版本更迭和备份。通过系统开发与测试，本系统基本已经达到了软件本身所设计的目标。

ABSTRACT

The current social science and technology has made great development and extremely high achievements, but it has gradually caused the problem of excessive waste production. Over time, this problem has continued to deteriorate and a series of new problems have spawned. For example, the problem of garbage disposal is getting more and more serious. With the increase in types of garbage, the state has introduced many policies, such as garbage classification. However, because the national quality level is not too high, and the concept of garbage classification is not known much, it is difficult to achieve the correct garbage classification. As a result, different types of garbage are too concentrated, which brings greater difficulties to the work of garbage disposal. Based on the above reasons, the current feasible method is to make the garbage disposal intelligent, automated, and synchronized.
This design is based on the WeChat applet design to implement a garbage classification system. According to the actual situation of garbage classification, I combined the concept, structure and basic principles and methods of the system to design and develop a small program with complete functions and good operation. This design is a system based on WeChat applets, which is used as the front-end and the back-end is developed in the cloud to realize the basic function of identifying garbage classification. This system mainly includes two modules. Users can classify garbage through text search or scanning and recognizing pictures; administrators can perform system version changes and backups in cloud development. Through system development and testing, this system has basically reached the goal designed by the software itself.
Key words: Garbage classification; WeChat applet; Cloud development
