摘　　要：随着我国高校教育的不断普及,大学生数量虽然激增,但是课堂学习氛围淡薄,甚至有逃课情况。这些现象严重影响着高校教师的教学计划以及对学生素质的培养。基于Zig Bee平台,设计了一套师生课堂应答系统,并重点阐述其软件设计。采用指纹识别替代传统的签到流程,加入副协调器以解决主协调器异常情况,利用Z-stack协议栈解决不同教室间误组网问题,并让学生能换一种方式对教学计划进行反馈。学生可利用硬件模块上的液晶屏和按键无线传递问题答题或表决信息,这使得师生间的交互变得更加方便与灵活。With the popularization of higher education in our country,although the number of undergraduates has surged,the atmosphere of classroom learning is weak and even students may skip classes. These phenomena seriously affect the teaching plans of college teachers and the cultivation of students＇ qualities. This paper based on the platform of Zig Bee,designs a set of teacher-student classroom interaction system,and emphasizes its design of software. The system uses fingerprinting to replace the traditional process of sign-in,adds a vice-coordinator to solve the abnormity of the master coordinator,uses the protocol stack of Z-stack to solve the problem of misconnecting between different classrooms,and allows students to change their way to response to the teaching plan. Students can use the LCD panel and buttons on hardware modules to wirelessly transmit their answers or voting information,which makes the interaction between teachers and students become more convenient and flexible.
