摘要
随着生活节奏加快与物品管理需求提升，便捷、安全的存储解决方案成为家庭、办公及公共场所的重要需求。传统存储方式存在操作繁琐、安全性不足、状态监测不便等问题，若缺乏有效的物品存储与管理手段，易导致物品存放混乱、取用效率低等情况。因此，研发一种兼具便捷操作、安全保障与智能管理功能的存储设备十分必要。
本设计提出一种基于 STM32F103C8T6 单片机的智能存储柜。系统主要功能包括：存储操作时，通过 4*4 矩阵键盘输入目标存储柜编号，按下确认键（#）后显示两种打开方式（1：密码、2：指纹），选择密码需输入 4 位密码，选择指纹则通过 AS608 指纹模块完成录入；取出操作时，直接输入 4 位密码或放置指纹，匹配成功后自动打开对应存储柜（共三个继电器，分别对应小、中、大不同规格柜子）；存储柜状态通过绿灯指示，未存放物品时绿灯点亮，存放物品后绿灯熄灭；柜门打开时，通过 CN-TTS 语音模块进行语音播报；系统通过内部 RTC 模块获取实时时间，并借助 OLED 显示屏显示当前时间及各柜门状态；同时，通过 ESP8266-12F WIFI 模块可实现柜门的远程控制。
该智能存储柜为物品存储提供了便捷、安全的解决方案，通过多样化开锁方式、清晰状态指示、语音提示及远程控制功能，有效提升物品管理效率与安全性，满足不同场景下的存储需求，改善用户使用体验。

Design of Intelligent Storage Cabinet for Single Chip Microcomputer
Abstract
With the acceleration of the pace of life and the increasing demand for item management, convenient and secure storage solutions have become an important requirement for homes, offices, and public places. The traditional storage method has problems such as cumbersome operation, insufficient security, and inconvenient status monitoring. If there is a lack of effective storage and management methods for items, it can easily lead to chaotic storage and low retrieval efficiency. Therefore, it is necessary to develop a storage device that combines convenient operation, security protection, and intelligent management functions.
This design proposes an intelligent storage cabinet based on STM32F103C8T6 microcontroller. The main functions of the system include: during storage operations, enter the target storage cabinet number through a 4 * 4 matrix keyboard, press the confirm button (#), and two opening methods (1: password, 2: fingerprint) will be displayed. To select the password, enter a 4-digit password, and to select the fingerprint, enter it through the AS608 fingerprint module; When performing the retrieval operation, directly enter a 4-digit password or place a fingerprint. After successful matching, the corresponding storage cabinet (consisting of three relays, corresponding to small, medium, and large cabinets of different specifications) will automatically open; The status of the storage cabinet is indicated by a green light, which lights up when no items are stored and goes out when items are stored; When the cabinet door is opened, voice broadcasting is performed through the CN-TTS voice module; The system obtains real-time time through an internal RTC module and displays the current time and the status of each cabinet door on an OLED display screen; Meanwhile, remote control of cabinet doors can be achieved through the ESP8266-12F WIFI module.
This intelligent storage cabinet provides a convenient and secure solution for item storage. Through diversified unlocking methods, clear status indicators, voice prompts, and remote control functions, it effectively improves the efficiency and security of item management, meets storage needs in different scenarios, and improves user experience.
