摘 要
在现代生活中，家长对儿童的安全和学习管理需求日益增加，尤其是对儿童日常出行和学习用品管理的关注。基于此，本设计提出了一款基于 STM32F103C8T6 单片机的儿童智能书包，旨在通过智能化手段提升儿童的安全性和学习便利性，同时为家长提供实时监控与管理的工具。
该智能书包具备多种实用功能。该系统通过RFID传感器检测书包内课本是否带齐，用户通过按键操作启动检测流程，检测完成后再次按下确认按键，系统将根据检测结果进行声光报警提醒，若课本齐全则不发出报警信号。通过GPS模块实时获取儿童的位置信息，确保其出行安全。语音识别模块可精准识别儿童的紧急呼叫，如“救命”，并立即将当前定位信息通过短信发送至监护人手机。系统还采用AT24C02存储芯片记录每天需要携带的课本信息，并通过OLED显示屏清晰展示当天需携带的课本内容。4G模块用于联网获取网络时间，并将检测数据传输至手机端，家长可在手机端灵活设置儿童需携带的课本种类，如语文、数学、英语、美术、品德等，实现个性化管理。
实物测试表明，该系统运行稳定，功能完善，操作简便，有效提升了儿童的安全性和学习便利性，具有良好的应用前景。

Abstract
In modern life, parents’ demand for children’s safety and learning management is increasing, especially their attention to children’s daily travel and management of learning materials. Based on this, this design proposes a children’s smart backpack based on STM32F103C8T6 microcontroller, aiming to improve children’s safety and learning convenience through intelligent means, while providing parents with real-time monitoring and management tools.
This smart backpack has multiple practical functions. The system uses RFID sensors to detect whether all textbooks are in the backpack. The user initiates the detection process by pressing a button, and after the detection is completed, presses the confirm button again. The system will issue an audible and visual alarm reminder based on the detection results. If all textbooks are complete, no alarm signal will be issued. Real time acquisition of children’s location information through GPS module to ensure their travel safety. The voice recognition module can accurately recognize children’s emergency calls, such as “help”, and immediately send the current location information to the guardian’s mobile phone via SMS. The system also uses AT24C02 storage chip to record the textbook information that needs to be carried every day, and displays the textbook content that needs to be carried that day clearly through OLED display screen. The 4G module is used to connect to the internet to obtain network time and transmit detection data to the mobile phone. Parents can flexibly set the types of textbooks that their children need to carry on the mobile phone, such as Chinese, mathematics, English, art, morality, etc., to achieve personalized management.
Physical testing has shown that the system runs stably, has complete functions, is easy to operate, effectively improves children’s safety and learning convenience, and has good application prospects.
