Classroom Interaction System Based On Wireless Communication Research

In recent years,with the rapid development of various communication technologies,all walks of life in the society have continuously improved the level of information technology.The classroom interaction system,which is convenient for classroom information interaction and helps teachers to acquaint students' learning status in real time,has attracted more and more attention.In this paper,firstly we analyzes and studies the application requirements and main functions of the classroom interaction system,and designs the classroom interaction system based on wireless communication,which is consist of a teacher receiving terminal,a wireless receiving terminal,a student handheld terminal,a teacher receiving terminal host computer software,a student handheld terminal host computer software,and a data management website.We uses USB communication,serial port time-sharing communication,Zigbee wireless communication,web Socket and other technologies to realize data communication between multiple modules,and has made in-depth research and improvement on some of the key technologies.On the basis of ensuring reliable communication,we achieve the aim that the handheld terminal can normally use for one month without charging is realized.The main work of the thesis:(1)Starting with the needs analysis of the classroom interaction system,we design the overall architecture of the classroom interaction system and device module function in the system.(2)We detailed designed of classroom interaction system based on wireless communication,including communication mode selection,chip selection,hardware circuit configuration and so on.(3)Embedded application development of classroom interaction system based on wireless communication.Design and implement the program development of the teacher receiving terminal,the wireless receiving terminal and the student handheld terminal in the classroom interactive system.In the student handheld terminals,special research and design of wireless communication anti-interference and low power consumption have been made,and design functions and reliability tests have been done for embedded modules.(4)Development of PC software and data management website for classroom interaction system based on wireless communication.The teacher's receiving terminal PC software,student handheld terminal PC software and data management website program are designed and implemented in the classroom interactive system.
