本文介绍了一种基于STM32F103C8T6单片机的智能垃圾桶设计。该垃圾桶具备多种功能，包括语音识别、手动开启、重量检测、装满检测、打包模拟、蜂鸣器预警以及紫外线消毒等。通过语音识别模块，垃圾桶能够识别不同种类的垃圾，并自动打开对应的垃圾桶。同时，用户还可以通过按键手动打开特定垃圾桶。重量检测是本设计的核心功能，采用薄片式压力传感器配合分离式红外对射管，能够准确测量垃圾桶内的重量。当垃圾桶重量达到设定的最大值或红外对射管检测到垃圾满载时，垃圾桶会被认定为已满。此时，系统会模拟继电器执行打包动作，并触发蜂鸣器预警，提醒工作人员及时清理垃圾。清理完成后，垃圾桶会恢复正常运行。为了确保卫生，该智能垃圾桶还配备了紫外线消毒功能。定时间隔内，系统会自动利用紫外线对垃圾桶进行消毒杀菌，保持垃圾桶内的卫生环境。为了提供实时数据展示，垃圾桶还搭载了OLED显示屏，能够显示各种测量数据和状态信息。本设计充分利用了STM32F103C8T6单片机的强大功能和灵活性，实现了垃圾分类识别、智能控制和健康卫生的综合功能。在未来，该智能垃圾桶有望在城市公共场所、办公楼宇等场景中推广应用，有效提高垃圾分类处理效率，改善城市环境质量，提升城市居民的生活品质。

Abstract
This paper presents a design of an intelligent garbage bin based on the STM32F103C8T6 microcontroller. The garbage bin is equipped with various functionalities, including voice recognition, manual activation, weight detection, fullness detection, simulated packing, buzzer warning, and UV disinfection. With the voice recognition module, the garbage bin can identify different types of trash and automatically open the corresponding bin. Additionally, users can manually open specific bins using buttons.The core feature of this design is the weight detection system, which utilizes a thin-film pressure sensor combined with a separated infrared emitter-detector pair to accurately measure the weight inside the garbage bin. When the garbage bin reaches its maximum weight or the infrared detection indicates it is full, the bin is recognized as full. In such cases, the system simulates a relay to trigger the packing action and activates the buzzer as a warning to prompt the staff to clean the trash. After the cleaning is completed, the garbage bin resumes normal operation.To ensure hygiene, the intelligent garbage bin is equipped with a UV disinfection function. At regular intervals, the system automatically uses UV light to disinfect and sterilize the garbage bin, maintaining a clean environment inside.Real-time data display is achieved by incorporating an OLED screen, which shows various measurement data and status information.This design makes full use of the powerful features and flexibility of the STM32F103C8T6 microcontroller, achieving comprehensive functionality for garbage classification recognition, intelligent control, and hygiene maintenance. In the future, this intelligent garbage bin is expected to be widely applied in public places and office buildings, effectively improving garbage classification efficiency, enhancing urban environmental quality, and elevating the quality of life for city residents.
