摘要
随着高校师生对快递服务需求的日益增长，高效、安全的快递存取方式成为校园后勤服务的重要组成部分。传统高校快递存取多依赖人工值守，存在取件效率低、错拿漏拿风险高、信息记录繁琐等问题，难以满足师生对便捷存取的需求。
基于 STM32F103C8T6 单片机的高校快递存取柜控制系统，整合了继电器模块（带动电磁锁）、语音模块、OLED 显示屏、按键及短信发送模块等硬件，实现了多项核心功能：通过 3 个继电器控制 3 个不同大小柜子的电磁锁，实现柜门开关；快递员输入正确用户名和密码后，可选择柜门、设置取件码并输入取件人手机号，系统将取件码通过短信发送给取件人；取件人通过输入取件码完成取件；每步操作均有语音提示；OLED 显示屏实时显示操作步骤、取件码及柜门状态。
该系统的实现，有效提升了高校快递存取的自动化与便捷性，降低了人工成本，保障了快递存取的安全性，为高校快递管理提供了高效解决方案，同时为同类存取柜系统的研发提供参考，具有较高的实用价值。

ABSTRACT
With the increasing demand for express services among college teachers and students, efficient and secure express pick-up and drop-off methods have become an important part of campus logistics services. Traditional college express pick-up and drop-off mostly rely on manual attendance, which has problems such as low pick-up efficiency, high risk of wrong or missing pick-ups, and cumbersome information recording, making it difficult to meet the needs of teachers and students for convenient access.
The college express cabinet control system based on the STM32F103C8T6 microcontroller integrates hardware such as relay modules (driving electromagnetic locks), voice modules, OLED displays, buttons, and SMS sending modules, realizing multiple core functions: controlling the electromagnetic locks of 3 cabinets of different sizes through 3 relays to open and close the cabinet doors; after the courier enters the correct username and password, they can select the cabinet door, set the pick-up code, and enter the recipient’s mobile phone number, and the system will send the pick-up code to the recipient via SMS; the recipient can pick up the express by entering the pick-up code; each operation is accompanied by voice prompts; the OLED display real-time shows the operation steps, pick-up code, and cabinet door status.
The implementation of this system effectively improves the automation and convenience of college express pick-up and drop-off, reduces labor costs, ensures the security of express access, provides an efficient solution for college express management, and also offers a reference for the research and development of similar access cabinet systems, with high practical value.
