基于ZigBee的互动教学系统学生端设计

基于PI教学法思想,利用ZigBee技术的近距离、低功耗、低数据速率等特点,提出一种基于ZigBee技术提高课堂教学效果的互动教学系统.该系统分为教师端和学生端.教师端可以使教师实时掌握学生上课情况,以实现高效教学.学生端设计采用的是TI公司CC2530内置加强版8051内核微控制器,通过LED灯显示接收信息和矩阵键盘输入信息,以实现上课签到、回答问题、匿名对教师进行评价等功能.学生端能够满足互动教学系统的功能要求,并且因其低成本和小型化特点易于在教学实践中推广应用.

Design of Student Terminal of Interactive Teaching System Based on ZigBee

Based on the idea of PI teaching,using ZigBee technology characteristics of close range,low power and low data rate,a new interactive teaching system based on ZigBee technology to improve the effectiveness of teaching is proposed.The system is divided into the terminals of the teacher and the student.The teacher''s terminal can enable teachers to master the students''studying in real time,so as to achieve effective teaching.The student terminal uses TI''s CC2530 built-in enhanced version of the 8051 kernel microcontroller,through the LED lamp to display received information and the matrix keyboard inputting information,which can realize the function such as class attendance,answer questions,anonymous evaluation of teachers.The student terminal can meet the functional requirements of interactive teaching system,and because of its low cost and miniaturization characteristics,it is easy to be popularized and applied to teaching practice.
