项目编号：mcuclub-dz-308
设计简介：
项目名：学生考勤系统（实物）
项目编号：mcuclub-dz-308
单片机类型：STM32F103C8T6
具体功能：
1、通过RFID进行学生刷卡考勤（3张卡模拟，刷卡后显示学生姓名及学号（甲同学100001、乙同学100002、丙同学100003））
2、通过RTC内部时钟获取时间，并可通过按键修正时间（3个按键）
3、通过确认键确认，确认后，未到的属于缺勤，通过AT24C02记录时间及缺勤人学号，通过一个按键进入查看考勤记录模式，通过另外两个按键可上下查看记录
4、刷卡成功后语音播报（签到成功）

摘 要
积极主动的进行考勤管理工作，不仅可以端正学习态度，还有利于学校安全防范工作的开展。传统点名的考勤方式在一定程度上起到了积极的作用，但也存在占用上课时间、影响学习气氛、存在冒名顶戴等问题。随着相关技术的发展，刷卡考勤被广泛应用，首先电磁卡具有唯一性、可靠性和准确性。其次，考勤速度快，学生进入教室前刷一下卡即可，最后，由于考勤机都是由计算机后台记录，所以这种方式易于储存，方便统计。
为了实现学生考勤的智能化管理，基于单片机和传感器技术设计一款学生考勤监测系统，本系统通过3张不同的RFID卡表示3个不同的学生，并通过OLED显示屏显示学生姓名、班级和学号，当按下确认按键后，未签到的属于缺勤，通过AT24C02记录时间及缺勤人学号。此外，可以通过一个按键进入查看考勤记录模式，还可以通过另外两个按键可上下查看记录，共同完成学生考勤监测。
通过实物测试，该学生考勤系统基本实现了预定功能，明显提高学校考勤管理效率，可以进行普及和推广。

Abstract
Active attendance management work, not only can correct the learning attitude, but also conducive to the development of school safety prevention work. The traditional attendance method plays a positive role to a certain extent, but there are also problems such as occupying class time, affecting the learning atmosphere, and wearing false names. With the development of related technologies, card attendance is widely used, first of all, the electromagnetic card has uniqueness, reliability and accuracy. Secondly, the attendance speed is fast, students can swipe the card before entering the classroom, and finally, because the attendance machine is recorded by the computer background, so this way is easy to store and convenient statistics.
In order to realize the intelligent management of student attendance, a student attendance monitoring system is designed based on single-chip microcomputer and sensor technology. This system represents 3 different students through 3 different RFID cards, and displays the student’s name, class and student number through OLED display. When the confirmation button is pressed, those who do not sign in are absent. Record time and absentee number via AT24C02. In addition, you can enter the attendance record mode through one key, and you can also view the record through the other two keys to jointly complete the student attendance monitoring.
Through the physical test, the student attendance system basically realizes the scheduled function, obviously improves the efficiency of school attendance management, and can be popularized and promoted.
