基于STM32的储物柜防潮防盗监控装置设计
摘要
随着城市公共设施与商业场所储物柜使用量的持续增长，储物柜长期处于无人值守的公共环境中，其内部环境状态与安全防护直接影响存放物品的完好性与使用者的财产安全。环境湿度过高、意外进水、柜体遭受剧烈撞击或撬动等问题易引发物品受潮霉变、积水损坏甚至失窃等严重后果，不仅造成用户财产损失，也增加了管理方的运维负担与安全责任。传统储物柜大多仅具备基础存储功能，缺乏对内部环境参数与柜体安全状态的实时感知能力，依赖人工定期巡检排查，存在监测盲区大、异常发现滞后、无法实时预警等缺陷，难以实现储物柜安全状态的动态管控。本文提出一种基于STM32F103C8T6单片机与4G通信技术的储物柜防潮防盗监控装置设计方案。系统集成振动检测、进水检测、温湿度监测、本地声光报警、4G短信远程推送、自定义报警阈值、OLED实时显示等核心功能。通过SW-420震动传感器、雨量检测模块、DHT11温湿度传感器实时采集储物柜柜体震动状态、内部积水情况及环境温湿度数据，将采集参数与用户预设安全阈值自动比对；当检测到柜体发生剧烈震动、内部存在积水或温湿度超出设定范围时，设备即时触发本地三声声光报警，同时通过4G模块向管理人员手机发送预警短信，实现异常状态的快速远程通知；系统搭载独立按键支持各项报警阈值自定义调节，搭配OLED显示屏实时本地展示全部监测数据。本系统有效解决了传统储物柜运维中人工巡检效率低、异常预警不及时、安全隐患难追溯的痛点，实现储物柜环境状态与安全防护的全天候自动监测、异常实时报警、远程短信通知，大幅提升公共储物设施的智能化安全管理水平，具备良好的实际应用价值与推广前景。

Abstract
With the continuous growth in the use of lockers in urban public facilities and commercial places, lockers are often located in unattended public environments for long periods, and their internal environmental conditions and security protection directly affect the integrity of stored items and the property safety of users. Problems such as excessive environmental humidity, accidental water ingress, and severe impact or prying of the cabinet body can easily lead to serious consequences such as moisture mildew, water damage and even theft of stored items, which not only causes property losses to users but also increases the operation and maintenance burden and safety responsibility of management parties. Traditional lockers mostly only have basic storage functions and lack the ability to perceive internal environmental parameters and cabinet security status in real time. They rely on manual periodic inspections, which suffer from large monitoring blind spots, delayed anomaly detection, and inability to provide real-time early warnings, making it difficult to achieve dynamic management of locker safety status. This paper proposes a design scheme for a moisture-proof and anti-theft monitoring device for lockers based on STM32F103C8T6 microcontroller and 4G communication technology. The system integrates core functions such as vibration detection, water ingress detection, temperature and humidity monitoring, local audible and visual alarms, 4G SMS remote push, customizable alarm thresholds, and OLED real-time display. Through the SW-420 vibration sensor, rainfall detection module and DHT11 temperature and humidity sensor, the system collects real-time data on cabinet vibration status, internal water accumulation and ambient temperature and humidity, and automatically compares the collected parameters with the safety thresholds preset by users. When severe cabinet vibration, internal water accumulation or temperature and humidity exceeding the set range is detected, the device immediately triggers local three-time audible and visual alarms, and simultaneously sends early warning SMS messages to managers’ mobile phones through the 4G module, realizing rapid remote notification of abnormal conditions. Equipped with independent buttons, the system supports custom adjustment of various alarm thresholds, and matches OLED display screen to locally display all monitoring data in real time. This system effectively solves the pain points of low efficiency of manual inspection, untimely abnormal early warning, and difficult traceability of safety hazards in traditional locker maintenance. It realizes all-weather automatic monitoring of locker environmental status and safety protection, real-time abnormal alarming, and remote SMS notification, greatly improving the intelligent safety management level of public storage facilities, and has excellent practical application value and promotion prospects.
