摘要
学生考勤是培养学生良好学习行为习惯和提高学生自学能力的重要举措,传统纸质版签到考勤方式存在代签弊端,为提高学生素质建设良好学风提出了基于STM32的便捷课堂考勤系统。考勤系统首先利用电容式指纹传感器进行指纹采集,然后将采集的指纹与预先建好的指纹数据库中指纹信息对比,并将最终匹配结果通过蓝牙上传至上位机考勤管理系统,考勤管理系统将学生考勤情况存入SQL数据库。与传统的考勤系统相比体积小、功耗低、更加便携的特点,经过实验测试,该考勤系统达到设计要求,在高校学生考勤管理中有一定的价值。
Student attendance is an important measure to cultivate students＂ good learning habits and improve students＇ self-learning ability. The traditional way of sign in is write on paper, it might be checkins-by-proxy. In order to improve the quality of students and build a good style of study, the paper presents a convenient classroom attendance system based on STM32. The attendance system first uses the capacitive fingerprint sensor for fingerprint collection, and com- pares the acquired fingerprint with the fingerprint information in the fingerprint database, and then uploads the matching result to the host computer＇s attendance management system by Bluetooth. The system stores the data of students＇ at- tendance into the SQL database. Compared with the traditional time and attendance system, small size, low power con- sumption, more portable features. After the experimental test, the attendance system to meet the design requirements, with great practical value in College Students＇ Attendance.
