摘　　要：针对当前课堂应答系统与课堂考勤系统彼此分离,未实现有效的整合,以及这两套系统在教学使用中存在的问题与缺点,提出一种集智能考勤系统与智能应答(投票)系统于一体的交互式智能教学反馈系统。系统基于ZigBee技术和指纹识别技术,通过便携式无线指纹识别终端实现自动签到,通过智能应答终端实现课堂上师生的互动,通过ZigBee网络实现无线传输,通过上位机统计结果,并将考勤信息、回答问题情况上传到远端云平台。实现自动签到、顺序点名、随机点名、回答问题、投票等功能。测试结果表明,系统具有功能完善、使用方便、功耗低等优点,满足交互式课堂的各种需求,明显提高了授课效果。In order to solve the existing problem that the classroom response system and classroom attendance system are seperate,an interactive and intelligent teaching feedback system with intelligent attendance and intelligent response(voting) is proposed in this paper.The ZigBee technology and fingerprint identification technology are used in the system.The portable wireless fingerprint identification terminals are used to complete attendance.The responding terminals are used to implement teacher-student interactions,and the ZigBee networks are used for wireless transmission.Moreover,an upper computer software is used to collect information of attendance and responding,and then the information is uploaded to the cloud platform.The functions of this system include automatic check-in,sequential name,random name,answering questions and voting.The test results show that the system has the advantages of complete functions,convenient use,lower power consumption,etc.It satisfies the various needs of the interactive classroom and it can obviously improve the teaching effect.
