摘要
在信息安全日益受到重视的当下，手提文件箱作为重要文件和物品的载体，其防盗性能的高低直接关系到信息与财产的安全。传统的机械锁具防盗方式，存在钥匙易丢失、被盗配，以及无法实时监控和远程预警等问题，难以满足现代场景下对文件箱安全防护的高要求。
基于 STM32F103C8T6 单片机的手提文件箱防盗设计，整合了 4*4 矩阵键盘、AS608 指纹模块、RFID 卡模块、AT24C02 存储模块、蜂鸣器、ESP8266 WIFI 模块、继电器（控制磁锁和自毁装置）、OLED 显示屏、GPS + 北斗定位模块等，实现了文件箱的多重防盗保护与智能管理。系统核心功能包括：通过矩阵键盘进行密码输入（0-9 为数字键，为删除键，# 为确定键，A 为电源启动键，B 为重置密码键，C 为添加删除指纹，D 为添加删除卡），其中重置密码需经管理员密码、旧密码、新密码、再次新密码的流程；添加或删除指纹、RFID 卡均需先输入管理员密码；借助 AT24C02 存储密码，实现掉电保存；当输入密码或指纹总错误次数≥3 次时，蜂鸣器报警 30s，同时锁定键盘及指纹模块 1 分钟，并通过 ESP8266 WIFI 模块将 “密码错误次数过多，请速速查看” 的信息发送至手机端；通过继电器控制磁锁，模拟开锁和关锁操作；OLED 显示屏会以号形式显示输入的密码，且输入密码时可在前后加入扰乱码，只要包含正确密码即可验证通过；利用 GPS + 北斗定位模块实时监测文件箱位置，当密码输入错误次数过多时，系统将位置信息通过 WIFI 模块发送到手机，手机端还可控制由继电器操控的自毁功能；此外，通过 WIFI 模块能远程手动控制文件销毁功能，并实时查看文件箱位置信息。
该设计有效提升了手提文件箱的防盗安全性与智能化管理水平，为重要文件和物品的安全防护提供了可靠保障，同时也为同类防盗设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
In an era where information security is increasingly valued, the anti-theft performance of portable file boxes, as carriers of important documents and items, directly relates to the security of information and property. Traditional mechanical lock anti-theft methods have problems such as easy loss or duplication of keys, inability to monitor in real-time and remote early warning, making them difficult to meet the high requirements for the security protection of file boxes in modern scenarios.
The anti-theft design of the portable file box based on the STM32F103C8T6 microcontroller integrates a 4*4 matrix keyboard, AS608 fingerprint module, RFID card module, AT24C02 storage module, buzzer, ESP8266 WIFI module, relays (controlling magnetic locks and self-destruct devices), OLED display, GPS+Beidou positioning module, etc., realizing multiple anti-theft protection and intelligent management of the file box. The core functions of the system include: password input through the matrix keyboard (0-9 as numeric keys, * as the delete key, # as the confirm key, A as the power start key, B as the password reset key, C as the add/delete fingerprint key, D as the add/delete card key). The password reset process requires the administrator password, old password, new password, and re-entering the new password; adding or deleting fingerprints and RFID cards requires entering the administrator password first; using AT24C02 to store passwords to achieve power-off preservation; when the total number of incorrect password or fingerprint inputs is ≥3 times, the buzzer alarms for 30 seconds, and at the same time locks the keyboard and fingerprint module for 1 minute, and sends the message "Too many incorrect password attempts, please check immediately" to the mobile phone through the ESP8266 WIFI module; controlling the magnetic lock through a relay to simulate unlocking and locking operations; the OLED display shows the entered password in the form of *, and when entering the password, disturbance codes can be added before and after, as long as the correct password is included, the verification can pass; using the GPS+Beidou positioning module to monitor the position of the file box in real-time, when there are too many incorrect password inputs, the system sends the position information to the mobile phone through the WIFI module, and the mobile phone can control the self-destruct function controlled by a relay; in addition, the file destruction function can be manually controlled remotely through the WIFI module, and the position information of the file box can be viewed in real-time.
This design effectively improves the anti-theft security and intelligent management level of the portable file box, provides a reliable guarantee for the security protection of important documents and items, and also provides a reference for the research and development of similar anti-theft equipment, with high practical application value.
