基于TCP协议的多媒体教室远程管理系统的设计

Design of the Remote Management System of Multimedia Classroom Based on TCP Protocol

本文主要讨论了多媒体教室远程管理系统的软件设计部分。下位机软件模块包括主程序、射频读卡子程序和网络通信子程序,网络通信子程序模块重点阐述了TCP协议驱动层的基本方法和TCP连接建立的三次握手过程;上位机软件模块主要是监控主程序,重点阐述消息包的处理过程;数据接口通过一卡通和教务的web服务接口完成数据同步。最后,总结了系统的设计意义。

This article mainly discusses the software design of multimedia classroom remote management system.The software cludes lower machine contains main program,RFID subroutine and network communications subroutine.The network communications subroutine focuses on basic methods of TCP protocol driver layer and the process of TCP＇s three handshake;the main software of upper monitor is monitor master program.The article particularly explains processing procedure of the message packets;the data interfaces complete data synchronization through the web services provided by campus card system and educational administration system.Finally,the article concludes the system＇s design significance.
