摘要
随着糖尿病患者对胰岛素依赖度的提升，胰岛素的存储质量直接影响其药效 —— 胰岛素需在 2-8℃低温环境下保存，温度过高易导致药效失效，过低则可能冻结破坏分子结构，若无法实时监控存储温度并及时干预，将严重影响患者治疗效果，甚至引发健康风险。当前传统存储设备多依赖人工查看温度计，存在监控不及时、调节滞后等问题，难以满足胰岛素精准存储需求。因此，研发一种能实时监测温度、自动控温且支持远程交互的胰岛素低温存储监控系统十分必要。
本设计提出一种基于 STM32F103C8T6 单片机的胰岛素低温存储监控系统。系统主要功能包括：通过 DS18B20 温度传感器检测胰岛素存储环境温度，当温度高于设置最大值时，自动启动制冷片制冷并开启风扇将冷空气送入存储空间，直至温度降至设置最小值以下；若温度持续高于设置最高值，系统触发声光报警提醒；用户可通过按键本地设置温度上下限值；通过 OLED 显示屏实时显示当前检测温度、温度阈值及设备工作状态；同时，系统通过 ESP8266-12F WIFI 模块将检测数据传输至手机端，用户还可在手机端远程设置温度最大值与最小值，控制制冷片开关。
该胰岛素低温存储监控系统的作用在于，为胰岛素存储提供了精准、可靠的温度监控与自动调控方案。通过实时监测、自动控温与远程交互，既能避免人工监控的疏漏，又能及时应对温度异常，保障胰岛素药效稳定，为糖尿病患者的治疗安全提供有力支持，提升用药保障水平。

Insulin Low Temperature Storage Monitoring System Based on STM32
Abstract
With the increase of insulin dependence in diabetes patients, the storage quality of insulin has a direct impact on its efficacy – insulin needs to be stored in a low temperature environment of 2-8 ℃. If the temperature is too high, it is easy to cause efficacy failure, and if the temperature is too low, it may freeze and destroy the molecular structure. If the storage temperature cannot be monitored in real time and timely intervention is not available, it will seriously affect the treatment effect of patients, and even cause health risks. Currently, traditional storage devices rely heavily on manual inspection of thermometers, which leads to issues such as untimely monitoring and delayed adjustment, making it difficult to meet the precise storage needs of insulin. Therefore, it is necessary to develop an insulin low-temperature storage monitoring system that can monitor temperature in real time, automatically control temperature, and support remote interaction.
This design proposes an insulin low-temperature storage monitoring system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the temperature of the insulin storage environment through the DS18B20 temperature sensor. When the temperature is higher than the set maximum value, the refrigeration unit will automatically start cooling and the fan will be turned on to send cold air into the storage space until the temperature drops below the set minimum value; If the temperature continues to exceed the set maximum value, the system will trigger an audible and visual alarm reminder; Users can set the upper and lower temperature limits locally by pressing the button; Real time display of current detected temperature, temperature threshold, and device operating status through OLED display screen; At the same time, the system transmits the detection data to the mobile phone through the ESP8266-12F WIFI module. Users can also remotely set the maximum and minimum temperature values on the mobile phone and control the switch of the cooling plate.
The function of this insulin low-temperature storage monitoring system is to provide accurate and reliable temperature monitoring and automatic regulation solutions for insulin storage. Through real-time monitoring, automatic temperature control and remote interaction, we can not only avoid the omission of manual monitoring, but also respond to temperature abnormalities in a timely manner, ensure the stability of insulin efficacy, provide strong support for the treatment safety of diabetes patients, and improve the level of drug security.
