The traditional roll call method relies on teachers calling names one by one and students responding, which has problems such as long time consumption, easy occurrence of proxy attendance, and cumbersome statistics, making it difficult to meet the management needs of large-scale classrooms.​The intelligent teacher roll call system based on STM32F103C8T6 microcontroller integrates OLED display, CN-TTS voice broadcast module, SU-03T voice recognition module, infrared counting sensor and buttons, realizing the automation and intellectualization of classroom roll call. The core functions of the system include: displaying students names and student numbers through the OLED display, synchronously broadcast by the CN-TTS module in sequence or randomly (supporting button switching mode); using the SU-03T module to recognize the voices here and present to complete the check-in, and judge whether the student is present through their response; if no one responds within 10 seconds, it is automatically deemed as absent; counting the actual number of students in the classroom through the infrared counting sensor at the door; after the roll call, the display automatically shows the list of absentees.​The implementation of this system effectively improves the efficiency of classroom roll call, reduces the cumbersomeness of manual operations, eliminates the phenomenon of proxy attendance, saves classroom time for teachers, and provides accurate attendance data for teaching management, with high practical application value.Keywords:STM32F103C8T6; Intelligent roll call; Voice recognition; CN-TTS broadcast; Infrared counting目录第1章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 显示模块选择2.1.3 语音播报模块选择2.1.4 语音识别模块选择2.1.5 红外计数传感器选择2.1.6 按键模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 显示模块电路3.3 语音播报模块电路3.4 语音识别模块电路3.5 红外计数传感器电路3.6 按键模块电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.10 OLED显示流程设计第 5 章 实物测试5.1 整体实物测试5.2 OLED 显示功能测试5.3 语音播报功能测试5.4 语音识别与签到功能测试5.5 红外计数功能测试5.6 压力传感器检测功能测试5.7 缺席名单显示功能测试5.8 系统联动功能测试第6章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
