摘要
在酒类存储领域，酒窖环境参数的稳定对酒品品质与存储安全起着决定性作用。传统酒窖环境管理多依赖人工检查和经验调控，存在数据记录不及时、环境波动难把控、异常响应滞后等问题，难以满足高品质酒类存储的严苛需求。
基于 STM32F103C8T6 单片机的酒窖存储环境监测与控制系统，整合了 DHT11 温湿度传感器、MQ-3 酒精浓度传感器、OLED 显示屏、按键及 4G 模块 AIR780，实现了对酒窖环境的实时监测、智能报警与远程管理。系统核心功能包括：通过 DHT11 监测环境温湿度，当数值超出设定阈值时触发声光报警；借助 MQ-3 检测酒精浓度，浓度异常时同步启动声光报警；支持通过按键现场设置各参数阈值；通过 OLED 显示屏实时展示各项监测数据；利用 4G 模块将数据发送至手机端，手机端也可远程设置各参数阈值。
该系统的实现，有效提升了酒窖存储环境监测的自动化与智能化水平，通过多参数实时监测、异常及时报警及远程管控，为酒类存储提供了稳定、安全的环境保障，同时为仓储环境监测设备的升级提供了参考，具有较高的实用价值与行业应用意义。

ABSTRACT
In the field of wine storage, the stability of environmental parameters in wine cellars plays a decisive role in the quality and storage safety of wine products. Traditional wine cellar environment management mostly relies on manual inspections and empirical regulation, which has problems such as untimely data recording, difficulty in controlling environmental fluctuations, and delayed response to abnormalities, making it difficult to meet the strict requirements for high-quality wine storage.
The wine cellar storage environment monitoring and control system based on the STM32F103C8T6 microcontroller integrates a DHT11 temperature and humidity sensor, an MQ-3 alcohol concentration sensor, an OLED display, buttons, and a 4G module AIR780, realizing real-time monitoring, intelligent alarm, and remote management of the wine cellar environment. The core functions of the system include: monitoring the ambient temperature and humidity through the DHT11, triggering an audible and visual alarm when the values exceed the set thresholds; detecting the alcohol concentration with the MQ-3, and synchronously activating the audible and visual alarm when the concentration is abnormal; supporting on-site setting of various parameter thresholds through buttons; displaying all monitoring data in real-time via the OLED display; and sending data to the mobile phone terminal using the 4G module, where the parameter thresholds can also be set remotely.
The implementation of this system has effectively improved the automation and intelligence level of wine cellar storage environment monitoring. Through multi-parameter real-time monitoring, timely abnormal alarms, and remote management, it provides a stable and safe environmental guarantee for wine storage. At the same time, it offers a reference for the upgrading of warehouse environment monitoring equipment, and has high practical value and industry application significance.
