摘要
传统旧衣物回收箱往往依赖人工巡检，存在回收状态监测不及时、安全隐患难察觉、管理效率低等问题，难以满足智能化回收管理的需求。
基于 STM32F103C8T6 单片机的旧衣物回收系统，整合了 MQ-2 烟雾传感器、DS18B20 温度检测模块、HC-SR04 超声波模块、DS1302 时钟模块、红外避障模块、按键、OLED 显示屏、ECB02 蓝牙模块及声光报警、消毒、门控等执行装置，实现了旧衣物回收过程的自动化监测与智能化管理。系统核心功能包括：通过 MQ-2 检测回收箱内烟雾值，超过设定最大值时触发声光报警；借助 DS18B20 监测箱内温度，高于最大值时启动声光报警；利用 HC-SR04 检测箱内剩余余量，小于最小值时显示回收箱已满；通过 DS1302 获取当前时间，可设置消毒时间，在消毒时段内门关闭进行消毒，当红外避障模块检测到有衣物投入时打开门并关闭消毒；支持通过按键设置烟雾值、温度值、剩余余量值，以及控制门的开关；OLED 显示屏实时显示各项测量数据；通过 ECB02 蓝牙模块将数据传输至手机端，同时可实现对消毒、关门、提示等功能的远程控制。
该系统有效提升了旧衣物回收箱的智能化管理水平，及时发现安全隐患和回收状态异常，减少了人工巡检成本，为旧衣物回收的高效运营提供了可靠解决方案，同时为同类回收设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
Traditional old clothes recycling bins often rely on manual inspection, with problems such as untimely monitoring of recycling status, difficulty in detecting potential safety hazards, and low management efficiency, which are difficult to meet the needs of intelligent recycling management.
The old clothes recycling system based on STM32F103C8T6 single-chip microcomputer integrates MQ-2 smoke sensor, DS18B20 temperature detection module, HC-SR04 ultrasonic module, DS1302 clock module, infrared obstacle avoidance module, buttons, OLED display, ECB02 Bluetooth module, and executive devices such as sound and light alarm, disinfection, and door control, realizing automatic monitoring and intelligent management of the old clothes recycling process. The core functions of the system include: detecting the smoke value in the recycling bin through MQ-2, triggering sound and light alarm when it exceeds the set maximum value; monitoring the temperature in the bin with DS18B20, starting sound and light alarm when it is higher than the maximum value; using HC-SR04 to detect the remaining capacity in the bin, displaying that the recycling bin is full when it is less than the minimum value; obtaining the current time through DS1302, which can set the disinfection time, closing the door for disinfection during the disinfection period, and opening the door and closing disinfection when the infrared obstacle avoidance module detects clothes being put in; supporting the setting of smoke value, temperature value, remaining capacity value through buttons, as well as controlling the opening and closing of the door; OLED display showing various measurement data in real time; transmitting data to the mobile phone through ECB02 Bluetooth module, and realizing remote control of functions such as disinfection, door closing, and prompting.
The system effectively improves the intelligent management level of old clothes recycling bins, timely detects potential safety hazards and abnormal recycling status, reduces the cost of manual inspection, provides a reliable solution for the efficient operation of old clothes recycling, and also provides a reference for the research and development of similar recycling equipment, with high practical application value.
