摘要
随着通信技术的发展,手机在我们生活中越发不可或缺,学生常常在上课时使用手机,严重影响学习,且在大阶梯教室中集中上课,传统点名费力费时。针对该问题,本文定位于各大高校多媒体教室,设计一种集学生点名和手机信号屏蔽功能为一体的装置,设计成U盘状,采用USB接口,随插随用,小巧轻便,内置蓝牙点名系统,帮助老师快速点名,并杜绝学生上课玩手机,提高课堂教学效率。
With the development of communication technology,mobile phones are indispensable in our lives.Students often use mobile phones during class,which seriously affect their learning,and it takes too much time to call the roll on manual basis in large classrooms.In response to this problem,this paper designs a device integrating the functions of roll call and mobile phone signal shielding for multimedia classrooms in colleges and universities.It is designed as a U disk,with a USB interface and a built-in Bluetooth roll call system,not only helping teachers quickly call the roll,but also preventing students from playing mobile phones in class,thus improving classroom teaching efficiency.
