【摘要】：随着计算机技术、多媒体技术日新月异的飞速发展,多媒体教学设备价格日益平民化,以计算机和投影机为基础的多媒体教室在各类学校也不断增加并渐渐得到了普及,改善了教学环境,但随之而来的却是专业技术人员的缺乏以及设备维护、管理难度的增加,甚至影响了教学质量,制约了现代教育技术在学校的应用与发展。实现对教室多媒体设备的集中控制和网络化管理是解决这一矛盾的关键,论文在造价经济、操作简便、使用可靠的原则下,研究并设计了一套适用于各类型学校的多媒体教室远程控制系统。该系统具有两部分的控制功能,一是教室内部多媒体设备的信号切换及控制,二是能够通过校园局域网对各教室的多媒体设备进行远程控制并监视其运行状态。论文首先分析了目前学校多媒体教室管理中存在的问题,概述了国内外对于多媒体教室远程控制系统和嵌入式系统的发展历史和研究现状,确定了论文的研究方向和设计思路；论文基于嵌入式技术,提出了模块化硬件设计思路,以凌阳SPCE061A单片机为主控芯片,详细论述了控制面板模块、音/视频及VGA信号切换模块、RS-232串口通信与投影机控制模块和网络接入模块的设计理念、工作原理和测试结果,分析了键盘去抖、多路信号的同步切换等技术,重点介绍了网络接入模块中精简型嵌入式TCP/IP协议的设计与实现；最后阐述了远程监控软件的功能要求,并详细介绍了程序的设计过程,提出了远程维修的思路和解决方法,分析了系统测试结果,通过测试,该多媒体教室远程控制系统具备较好的稳定性,达到了使用要求,具有实用及推广价值。
[Abstract]:With the rapid development of computer technology and multimedia technology, the price of multimedia teaching equipment is becoming more and more popular, and the multimedia classroom based on computer and projector is increasing and popularizing in all kinds of schools. The teaching environment has been improved, but the shortage of professional and technical personnel, the maintenance of equipment, the increase of management difficulty, and even the influence of teaching quality have restricted the application and development of modern educational technology in schools. The realization of centralized control and networked management of classroom multimedia equipment is the key to solve this contradiction. This paper studies and designs a set of multimedia classroom remote control system for all kinds of schools. The system has two parts of control function, one is the signal switching and control of the multimedia equipment in the classroom, the other is the remote control and monitoring of the multimedia equipment in each classroom through the campus local area network. Firstly, the paper analyzes the problems existing in the management of multimedia classroom, summarizes the development history and research status of multimedia classroom remote control system and embedded system at home and abroad, and determines the research direction and design idea of the paper. Based on the embedded technology, the paper puts forward the idea of modularization hardware design. Taking the Lingyang SPCE061A single chip computer as the main control chip, the control panel module is discussed in detail. The design concept, working principle and test results of RS-232 serial port communication and projector control module and network access module of audio / video and VGA signal switching module are analyzed. This paper mainly introduces the design and implementation of the simplified embedded TCP / IP protocol in the network access module, and finally expounds the functional requirements of the remote monitoring software, introduces the design process of the program in detail, and puts forward the ideas and solutions of remote maintenance. The system test results show that the remote control system of the multimedia classroom has good stability and meets the requirements of application. It has practical and popularized value.
