【摘要】：隨著計算機技術(shù)、多媒體技術(shù)日新月異的飛速發(fā)展,多媒體教學設(shè)備價格日益平民化,以計算機和投影機為基礎(chǔ)的多媒體教室在各類學校也不斷增加并漸漸得到了普及,改善了教學環(huán)境,但隨之而來的卻是專業(yè)技術(shù)人員的缺乏以及設(shè)備維護、管理難度的增加,甚至影響了教學質(zhì)量,制約了現(xiàn)代教育技術(shù)在學校的應(yīng)用與發(fā)展。 實現(xiàn)對教室多媒體設(shè)備的集中控制和網(wǎng)絡(luò)化管理是解決這一矛盾的關(guān)鍵,論文在造價經(jīng)濟、操作簡便、使用可靠的原則下,研究并設(shè)計了一套適用于各類型學校的多媒體教室遠程控制系統(tǒng)。該系統(tǒng)具有兩部分的控制功能,一是教室內(nèi)部多媒體設(shè)備的信號切換及控制,二是能夠通過校園局域網(wǎng)對各教室的多媒體設(shè)備進行遠程控制并監(jiān)視其運行狀態(tài)。 論文首先分析了目前學校多媒體教室管理中存在的問題,概述了國內(nèi)外對于多媒體教室遠程控制系統(tǒng)和嵌入式系統(tǒng)的發(fā)展歷史和研究現(xiàn)狀,確定了論文的研究方向和設(shè)計思路；論文基于嵌入式技術(shù),提出了模塊化硬件設(shè)計思路,以凌陽SPCE061A單片機為主控芯片,詳細論述了控制面板模塊、音/視頻及VGA信號切換模塊、RS-232串口通信與投影機控制模塊和網(wǎng)絡(luò)接入模塊的設(shè)計理念、工作原理和測試結(jié)果,分析了鍵盤去抖、多路信號的同步切換等技術(shù),重點介紹了網(wǎng)絡(luò)接入模塊中精簡型嵌入式TCP/IP協(xié)議的設(shè)計與實現(xiàn)；最后闡述了遠程監(jiān)控軟件的功能要求,并詳細介紹了程序的設(shè)計過程,提出了遠程維修的思路和解決方法,分析了系統(tǒng)測試結(jié)果,通過測試,該多媒體教室遠程控制系統(tǒng)具備較好的穩(wěn)定性,達到了使用要求,具有實用及推廣價值。
[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.
