摘要
在健康管理领域，药物储存环境的稳定性与服药的规律性直接影响用药安全与治疗效果。当前，普通药箱普遍缺乏温湿度调控功能，药物易因潮湿、高温变质；同时，中老年群体或慢性病患者常存在漏服、忘服药物的问题，且难以实时掌握药品余量，这些情况不仅降低治疗效果，还可能引发健康风险。此外，传统药箱功能单一，无法实现与用户的智能交互，难以满足现代健康管理的需求。因此，研发一款集药物存储保护、服药提醒、智能监测与交互功能于一体的智能提醒药箱具有重要实用价值。
本设计提出一种基于 STM32F103C8T6 单片机的智能提醒药箱。系统通过一个 DHT11 传感器监测药箱内部温湿度，温度过高时启动制冷继电器，湿度过高时触发加热与通风继电器，保障药物储存环境干燥稳定；借助按键可添加或删除服药提醒时间，到达预设时间后，CN-TTS 语音模块发出服药提醒，超半小时未服药则启动声光报警，同时 SG90 舵机自动打开药箱，红外避障管检测到药物放回后，10 秒内自动关闭药箱；触发 HX711 称重模块可实时检查药品余量；另一个DHT11 同步监测室内温湿度，温度较低时提醒添加衣物；ATGM332D-5N GPS 模块获取药箱位置；ESP8266-12F WiFi 模块将服药信息、药箱位置及服药数量同步至手机 APP；OLED 显示屏实时显示各项监测阈值与设置阈值。
该智能提醒药箱的作用在于，为用户提供了全方位的药物管理与健康辅助解决方案。通过精准的温湿度调控保障药物质量，智能服药提醒减少漏服风险，多维度监测与手机交互提升使用便捷性，助力用户养成规律服药习惯，保障用药安全，为家庭健康管理提供有力支持。

Intelligent reminder medicine boxr
Abstract
In the field of health management, the stability of drug storage environment and the regularity of medication directly affect medication safety and treatment efficacy. Currently, ordinary medicine cabinets generally lack temperature and humidity control functions, and drugs are prone to spoilage due to humidity and high temperatures; At the same time, middle-aged and elderly people or chronic disease patients often have the problem of missing or forgetting to take medication, and it is difficult to keep track of the remaining amount of medication in real time. These situations not only reduce treatment effectiveness, but may also pose health risks. In addition, traditional medicine boxes have a single function and cannot achieve intelligent interaction with users, making it difficult to meet the needs of modern health management. Therefore, developing an intelligent reminder medicine box that integrates drug storage protection, medication reminder, intelligent monitoring, and interactive functions has important practical value.
This design proposes an intelligent reminder medicine box based on STM32F103C8T6 microcontroller. The system monitors the temperature and humidity inside the medicine box through a DHT11 sensor. When the temperature is too high, the refrigeration relay is activated, and when the humidity is too high, the heating and ventilation relay is triggered to ensure a dry and stable drug storage environment; With the help of buttons, medication reminder times can be added or deleted. When the preset time is reached, the CN-TTS voice module will issue medication reminders. If medication is not taken for more than half an hour, an audible and visual alarm will be triggered. At the same time, the SG90 servo will automatically open the medicine box. After the infrared obstacle avoidance tube detects that the medication is returned, the medicine box will automatically close within 10 seconds; Triggering the HX711 weighing module can check the remaining amount of drugs in real time; Another DHT11 synchronously monitors indoor temperature and humidity, and reminds to add clothes when the temperature is low; ATGM332D-5N GPS module obtains the location of the medicine box; The ESP8266-12F WiFi module synchronizes medication information, medication box location, and medication quantity to the mobile app; The OLED display screen displays real-time monitoring thresholds and set thresholds.
The function of this intelligent reminder medicine box is to provide users with comprehensive drug management and health assistance solutions. By precise temperature and humidity control to ensure drug quality, intelligent medication reminders to reduce the risk of missed doses, multi-dimensional monitoring and mobile interaction to improve user convenience, help users develop regular medication habits, ensure medication safety, and provide strong support for family health management.
