Research On Network Multi-control System Of Multi-media Classroom

With the rapid development of network technology, multimedia technology and computer technology, our schools at all levels build more and more multimedia classroom in order to improve classroom teaching and ensure the quality of teaching. Contradiction between dramatic increase in the number of multimedia classrooms and shortage of multimedia classroom managers is increasingly clear. In order to realize the multimedia classroom equipment automation management without increasing number of managers and guarantee multimedia teaching equipment running reliably in the classroom,this article presents a multimedia classroom network group control system and its implementation.Multimedia classrooms group control system studied in this article is consisted of network group control host with failure warning equipment installed in the multimedia classroom and multimedia classroom network group control management platform software system installed in the network management center. Network group control hosts realize the sensor detect the teaching equipment (projector, electric screen, etc.) working status of the closed-loop real-time.This article designed hardware and embedded software of multimedia network group control host. Network group control host based on ARM9 embedded architecture, designed modules of the master control, audio and video processing, communications, automatic detection, enabled functions of the automatic warning of multimedia equipment failure,remote control, automatic feedback device working conditions, and then made the network group control touch-type host desktop control software, communications software.To make the system complete, there is a brief description of the network group control management software platform, it realized the functions such as remote control of multimedia classroom equipment, real-time detection of teaching equipment working status, automatic alarm notification report of teaching equipment impaired, classroom instruction curriculum management, access card issuer management, school student attendance management and so on. It introduced the master interface, the software of alarm, classroom curriculum management, student attendance card.The results show that this system is a new system for multimedia classroom equipment intelligent management and it will provide some reference to the intelligent management of multimedia classroom equipment.
