摘要
随着垃圾分类政策的推进与智能家居理念的普及,传统垃圾桶在分类准确性、使用便捷性及管理效率上的不足日益凸显。人工分类易出错、垃圾桶满溢难及时发现、清洁管理缺乏智能化手段等问题,不仅影响居住环境整洁,也增加了垃圾分类推行的难度。因此,研发一款兼具自动分类、状态监测与智能管理功能的垃圾桶系统,对提升垃圾分类效率、优化环境管理具有重要意义。
本设计提出一种基于 STM32F103C8T6 单片机的智能垃圾桶系统。系统核心功能包括:通过 SU-03T 语音识别模块识别垃圾种类,驱动两个 SG90 舵机自动打开对应垃圾桶(可回收垃圾、其它垃圾);支持按键手动控制垃圾桶开关,满足多样化操作需求;采用两个 FSR402 压力传感器测量垃圾重量,配合分离式红外对射管判断垃圾桶是否已满(任一条件满足即判定满溢),最大重量值可通过手机端灵活设置;垃圾桶满溢后触发蜂鸣器预警,此时仅支持按键打开,清理完成后恢复正常运行;可通过定时设置,利用紫外消毒灯实现周期性消毒杀菌;借助 ESP8266-12F WiFi 模块,管理人员可远程查看垃圾桶开关状态、垃圾重量、满溢情况,远程控制垃圾桶开关与消毒操作,且能设置消毒时间;当监测到垃圾桶满溢时,通过 SIM900A GSM 模块自动发送短信至清理人员手机,通知及时清运。
该智能垃圾桶系统的作用在于,为垃圾分类与环境管理提供了智能化解决方案。通过自动分类减少人工操作误差,通过多维度满溢监测与预警确保及时清运,通过远程管理与消毒控制提升管理效率,同时改善环境卫生,降低细菌滋生风险,助力垃圾分类政策高效落地,提升居住与公共环境品质。

Design of Electronic Blood Pressure Monitor Based on Single Chip Microcomputer
Abstract
With the improvement of living standards and the enhancement of health awareness, monitoring blood pressure and heart rate has become an important part of people’s attention to their own health. For middle-aged and elderly people, abnormal fluctuations in blood pressure and heart rate, if not monitored and treated in a timely manner, may lead to serious health problems and even endanger their lives. Therefore, it is necessary to develop a device that can conveniently and accurately monitor blood pressure and heart rate.
This design proposes an electronic blood pressure monitor based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the current user’s diastolic and systolic blood pressure through the blood pressure detection module; Using a heart rate detection module to measure the current user’s heart rate; The user initiates the measurement by pressing a button; When abnormal heart rate or blood pressure is detected, the system will sound and light an alarm; Display measurement values through OLED; At the same time, the system stores the detected blood pressure through a storage module, which can hold up to 20 sets, and users can view them by pressing a button.
The function of this electronic blood pressure monitor is to provide people with a convenient and effective tool for monitoring blood pressure and heart rate. By timely monitoring and alerting, it can help people detect health hazards as early as possible, facilitate timely measures, ensure physical health, and improve quality of life.
