【摘要】：隨著當代信息技術的飛速發(fā)展，人們獲取的信息量日益增多，對會議效率的追求越來越高，要求智能會議系統(tǒng)集成的功能越來越多。但是現(xiàn)有智能會議系統(tǒng)一般使用筆記本電腦作為會議終端，傳輸線纜繁多、交互性差、配套功能軟件不完善。充分利用現(xiàn)有的無線局域網(wǎng)通信技術、日益成熟的嵌入式技術和人機交互技術設計一款無需布線、可移動、交互性強、功能完善、布局快捷方便的嵌入式會議系統(tǒng)終端具有很高的現(xiàn)實價值。 本文以本地智能討論會議系統(tǒng)為應用背景，以嵌入式系統(tǒng)作為智能會議系統(tǒng)終端的開發(fā)平臺，設計并實現(xiàn)硬件平臺，開發(fā)配套功能軟件，制作出原理樣機，并通過實驗測試驗證設計的合理性，為智能會議系統(tǒng)終端設計提供一種新的解決方案。 以OMAP3530作為核心處理器，設計嵌入式智能會議系統(tǒng)終端，集成顯示功能模塊、音視頻采集模塊、網(wǎng)絡通信模塊、通用接口模塊。利用Cadence軟件設計硬件平臺，仿真驗證電路板設計的電磁兼容性、信號完整性。制作實驗板，通過實驗測試功能模塊的可用性。 在以上設計的嵌入式終端上集成現(xiàn)有超聲紅外定位裝置，開發(fā)驅動程序獲取定位數(shù)據(jù)。由超聲紅外定位技術出發(fā)，解析定位數(shù)據(jù)，設計并實現(xiàn)鼠標模擬、實時書寫等人機交互功能，解決現(xiàn)有智能會議系統(tǒng)終端無法手寫批注、筆式交互操作的問題。 建立無線局域通信網(wǎng)，通過預設控制協(xié)議完成代表機遠程控制主席機與主席機授權管理功能，，構建智能會議系統(tǒng)中端到端的大型交互系統(tǒng)。改變會議系統(tǒng)中“一方發(fā)言多方聽”現(xiàn)象，完善會議系統(tǒng)中的跨平臺高度交互，有效提高會議效率。 在上述技術基礎上，設計并實現(xiàn)人機交互、終端通信、會議簽到和電子投票等功能軟件，豐富完善現(xiàn)有智能會議系統(tǒng)功能。選擇基于Socket接口開發(fā)嵌入式操作系統(tǒng)與桌面操作系統(tǒng)的跨平臺TCP通信，建立主席機與代表機之間的TCP通信關系，在此基礎上開發(fā)會議系統(tǒng)的簽到和電子投票功能。制作原理樣機，測試智能會議系統(tǒng)的功能軟件。 主要貢獻如下： (1)提出智能會議系統(tǒng)終端集成超聲紅外定位的交互裝置的解決方案，開發(fā)出主席機與代表機之間跨平臺交互功能，建立智能會議系統(tǒng)中端到端大型交互系統(tǒng)。 (2)制作嵌入式智能會議系統(tǒng)終端原理樣機，集成開發(fā)跨平臺通信、人機交互、會議簽到和電子投票功能，豐富完善現(xiàn)有智能會議系統(tǒng)功能。 上述工作為本地智能討論會議系統(tǒng)終端的設計提供一套完整的方案，通過集成人機交互設備，開發(fā)會議系統(tǒng)中主席機與代表機的跨平臺交互功能，提升智能討論會議系統(tǒng)的交互性能，提高會議效率。對智能討論會議系統(tǒng)終端、跨平臺通信系統(tǒng)、人機交互設備等產品的研究和開發(fā)具有一定的參考價值。
[Abstract]:With the rapid development of contemporary information technology, people obtain more and more information, and the pursuit of conference efficiency is higher and higher, which requires more and more functions of intelligent conference system integration. However, the existing intelligent conference system generally uses notebook computer as the conference terminal, the transmission cable is numerous, the interaction is poor, and the supporting function software is not perfect. Making full use of the existing wireless local area network communication technology, the increasingly mature embedded technology and human-computer interaction technology to design an embedded conference system terminal without wiring, movable, interactive, perfect function, fast and convenient layout has a high practical value. This paper takes the local intelligent discussion conference system as the application background, takes the embedded system as the development platform of the intelligent conference system terminal, designs and implements the hardware platform, develops the supporting function software, makes the principle prototype, and verifies the rationality of the design through the experiment test, and provides a new solution for the intelligent conference system terminal design. With OMAP3530 as the core processor, the embedded intelligent conference system terminal is designed, which integrates display function module, audio and video capture module, network communication module and general interface module. The hardware platform is designed by Cadence software, and the electromagnetic compatibility and signal integrity of circuit board design are verified by simulation. Make the experimental board, through the experiment to test the availability of functional modules. The existing ultrasonic infrared positioning device is integrated on the embedded terminal designed above, and the driver is developed to obtain the positioning data. Based on the ultrasonic infrared positioning technology, the positioning data are analyzed, and the mouse simulation, real-time writing and other human-computer interaction functions are designed and realized to solve the problem that the existing intelligent conference system terminals can not write comments and pen interaction. The wireless local area communication network is established, and the remote control podium and podium authorization management function are completed by preset control protocol, and the large end-to-end interactive system in intelligent conference system is constructed. Change the phenomenon of "one party speaking and listening to each other" in the conference system, perfect the cross-platform high interaction in the conference system, and effectively improve the efficiency of the meeting. On the basis of the above technology, the functional software such as human-computer interaction, terminal communication, conference check-in and electronic voting is designed and implemented, which enriches and perfects the functions of the existing intelligent conference system. The cross-platform TCP communication between embedded operating system and desktop operating system is developed based on Socket interface, and the TCP communication relationship between podium and representative computer is established. On this basis, the check-in and electronic voting functions of conference system are developed. Make the prototype and test the function software of intelligent conference system. The main contributions are as follows: (1) the solution of integrated ultrasonic infrared positioning interactive device for intelligent conference system terminal is proposed, the cross-platform interaction function between podium and representative machine is developed, and the end-to-end large interactive system in intelligent conference system is established.
