设计简介：
项目名：存储柜（实物）
项目编号：mcuclub-dz-228
单片机类型：STM32F103C8T6
具体功能：
1、通过两个按键代表存和取
2、当按下存按键后，放入指纹，则录入指纹，并任意打开其中一个没有存放的柜子(三个柜子)，柜子存入东西后，电磁锁打开，当超过30s后没有关闭，则语音提醒“请关闭柜门”，如果关闭，对应绿灯点亮，表明已经存放物品
3、当按下取按键后，放入指纹，如果匹配成功，则打开对应的柜子，并删除指纹，对应绿灯熄灭，表明物品已经取走
4、管理员可通过一个管理员按键，打开所有柜子

基于单片机指纹存取储物柜的设计
摘 要
在当今社会，物品的安全存储和快速访问对于个人和组织来说至关重要。传统的储物柜和安全箱通常需要使用机械锁，密码或钥匙来保护物品，然而，这些方法存在被破解或遗失的风险。因此，需要一种更安全、便捷且高效的储物柜存取系统。此次设计一款基于STM32F103C8T6单片机的指纹存取储物柜设计具有多项功能，旨在提供安全、便捷的物品存取和管理系统。以下是项目的主要功能和亮点：存取按键：系统提供了两个按键，一个用于存放物品，另一个用于取回物品。这种简单的交互方式使用户能够轻松地存放和取回物品。指纹录入和识别：当用户按下存按键并放入指纹时，系统将录入指纹数据。用户可以选择存放物品在三个柜子中的任何一个。指纹成功录入后，系统会打开其中一个未存放物品的柜子。电磁锁控制：当柜子打开后，电磁锁将解锁，允许用户存放物品。如果柜子在30秒内没有关闭，系统将发出语音提醒：“请关闭柜门”。一旦柜门关闭，相应的绿灯将点亮，表示物品已经成功存放。指纹验证和柜子开启：当用户按下取按键并放入指纹时，系统将进行指纹验证。如果匹配成功，系统将打开相应的柜子，允许用户取回物品。一旦物品取走，相应的绿灯将熄灭，表示该柜子已经空闲。管理员模式：系统还提供了管理员按键，管理员可以使用它来打开所有柜子。这种功能可以用于维护、检查柜子或其他管理任务。
总的来说，这个项目为用户提供了一个安全、便捷的物品存取和管理系统，通过指纹技术确保了高度的安全性。未来可以考虑添加更多功能，如远程监控、记录存取日志以及增加柜子数量等，以提高系统的功能性和扩展性。

Abstract
In today’s society, the secure storage and quick access to belongings are of paramount importance for individuals and organizations. Traditional storage cabinets and safes typically rely on mechanical locks, passwords, or keys to protect items; however, these methods carry risks of being compromised or keys being lost. Therefore, there is a need for a more secure, convenient, and efficient storage and access system.The design of a fingerprint-based storage cabinet, based on the STM32F103C8T6 microcontroller, offers multiple functionalities aimed at providing a secure and convenient system for item storage and management. The following are the main features and highlights of the project:Access Buttons: The system provides two buttons, one for storing items and the other for retrieving them. This simple user interface allows users to easily store and retrieve items.Fingerprint Enrollment and Recognition: When a user presses the storage button and places their fingerprint, the system records the fingerprint data. Users can choose to store items in any of the three compartments. After successful fingerprint enrollment, the system opens one of the compartments that hasn’t been used.Electromagnetic Lock Control: When a compartment is opened, the electromagnetic lock is released, allowing users to store items. If the compartment remains open for more than 30 seconds, the system issues a voice prompt: “Please close the cabinet door.” Once the cabinet door is closed, the corresponding green light illuminates, indicating that the item has been successfully stored.Fingerprint Verification and Cabinet Access: When a user presses the retrieval button and places their fingerprint, the system performs fingerprint verification. If the verification is successful, the system opens the corresponding cabinet, allowing the user to retrieve items. Once the items are taken, the corresponding green light extinguishes, indicating that the cabinet is now available.Administrator Mode: The system also includes an administrator button that allows administrators to open all cabinets. This functionality can be used for maintenance, inspection of cabinets, or other administrative tasks.
In summary, this project provides users with a secure and convenient item storage and management system, utilizing fingerprint technology to ensure a high level of security. Future enhancements could include remote monitoring, logging access records, and expanding the number of cabinets to enhance the system’s functionality and scalability.
