i基于单片机的智能垃圾桶设计摘要：由于现在人家的生活水平越来越好，科学技术不断发展，大家的对生活的要求越来越高，大家都向往更好的生活质量，更好重视生活品质，尤其是对于居家生活更加重视，所以在这种形势下，出现了很多关于环境卫生的产品。在任何场所，垃圾无疑是最领人头疼的事情，所以对于垃圾桶的管理是非常重要的，有必要设计一款智能垃圾桶产品。而大量堆积在外的垃圾还会发出刺鼻的异味，既污染了环境也增加了人与细菌接触的几率。系统主要包括报警、垃圾桶状态检测、人体检测、指示灯、垃圾桶控制以及主控制器。系统通过人体检测信号，判断如果有人，则控制垃圾桶打开，可以对垃圾桶状态进行检测，垃圾桶是否满，并且通过报警提示。垃圾满采集选用红外对管模块。垃圾桶控制选择步进电机，步进电机驱动选择 ULN2003。选择 C 语言设计系统软件代码，C 语言使用简单，编辑器选择 Keil，进行代码编写、编译、执行，完成系统的功能，实现功能运行。关键词：STC89C52 单片机；垃圾桶控制；ULN2003；红外对管iiDesign of intelligent trash can based on single chip microcomputerAbstract：As people's living standards are getting better and better, science and technology are constantly developing, and people's requirements for life are getting higher and higher. Everyone is yearning for better quality of life and attaches more importance to quality of life, especially for home life. Therefore, in this situation, there are a lot of products about environmental health. In any place, garbage is undoubtedly the most troublesome thing, so the management of the trash can is very important, it is necessary to design a smart trash product. And a lot of waste outside can also emit a pungent smell, polluting the environment and increasing the chances of contact with bacteria. The system mainly includes alarm, trash status detection, human detection, indicator light, trash control and main controller. The system determines if there is someone by detecting the signal of human body, and then c...
