[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. (2) make the terminal prototype of embedded intelligent conference system, integrate and develop the functions of cross-platform communication, human-computer interaction, conference check-in and electronic voting, enrich and perfect the functions of the existing intelligent conference system. The above work provides a complete scheme for the design of the terminal of the local intelligent discussion conference system. By integrating the human-computer interaction equipment, the cross-platform interaction function between the host and the representative machine in the conference system is developed, so as to improve the interaction performance of the intelligent discussion conference system and improve the meeting efficiency. It has certain reference value for the research and development of intelligent discussion conference system terminal, cross-platform communication system, human-computer interaction equipment and so on.
