中文摘要:

现阶段,越南高校课堂考勤大都沿用传统的人工点名方式,效率低下且影响正常教学。为此本文应用射频识别(RFID)技术,开发课堂考勤信息的计算机管理系统。采用校园一卡通和TSW—F3RF型感应卡读写器作为身份标识和考勤设备;设计考勤信息数据库的局部、全局ER模型,并用MicrosoftAcceSS实现;用ViSUalBaSic编制用户界面。可实现考勤信息记录、学生请假、教师审核等多项功能。原型系统的实验测试结果验证了其有效性。该成果将有助于提高越南高校行政办公效率,推进校园信息化进程。

英文摘要:

The traditional roll-call is still widely used for the class attendance management in universities of Vietnam. The method is not only of low efficiency but also occupies the time for class teaching. This paper utilizes the radio frequency identification (RFID) technology and develops a computer system for managing the class attendance information. The campus IC card and TSW-F3RF card reader are selected as the identity punch and equipment, respectively. Both local and global ER models of the attendance information database are established, and then implemented by using Microsoft Access. The user interface is coded within Visual Basic language. The system has various functions such as attendance information record, absense application of students, and approal from the teacher, etc. The experimental results validate the effectiveness of the prototype. The developed system could greatly improve the administrative efficiency and promote the campus informatization in Vietnam.
