教室人数智能统计及播报系统设计

Design of classroom people counting and broadcast system

现今高校教师大多以口头点名的方式来考察学生的上课出勤情况。但是点名过程繁琐,浪费宝贵的上课时间。系统采用单片机STC89C52为核心部件,运用红外感应技术来统计教室中的实际人数并通过液晶屏显示以及语音播出。帮助教师准确掌握上课学生人数,节省点名时间,有利于教师教学工作的开展。

Today, most college teachers examine students＇ class attendance by oral roll call. However the process is very complicated and wasting valuable class time. The system uses the STC89C52 singlechip microcomputer as the core component and uses infrared sensor technology to count the actual students＇ numble of the classroom and broadcast the number by voice. It can help teachers know the number of the students accurately and save the time of roll call. It also has good and positive effects on teachers＇ teaching.
