Multimedia Classrooms Of The Centralized Monitoring System

Along with the rapid development of computer application technology, network and multi-media technology, all or different levels school design various teaching activities by providing a whole new teaching environments and using advanced methods of teaching. It leads to grow more and more classroom by multi-media teaching equipment. Such as computer and projector and so on. While the multi-media classrooms are built up, Multimedia Concentrated Controller is one of indispensable important equipment. Multimedia Concentrated Controller is the most up-to-data science and technology connecting with electronic technology, computer technology and net technology. It can control all of the equipments. The typical characteristic is that operational process become simlpy, and can be used easily.This paper analyses the computer multimedia technology through the campus net equipment concentrated controller. Then the design of hardware and software is presented. Specially, it discusses the long-distance communication, control and infrared remote code studing technology.This article expounds the modularization designed thought about multimedia control system and the principle of distributed control, and elucidates exactly the control principle of the controlling module. The writer also suggests show does achieve the fundamental means of the distributed control that base on the multiple single-chip digital communication technique and the digital communication technique between single-chip and PC. The infrared remote control module in this system has the function of "self study", and it can learn most of the coding of the infrared remote controllers and able to save them in this system. So this can remote control most of multimedia equipments instead of change them circuitry.In the end, the high-speed data acquisition module is very good in function and application. It makes develop project more rapid and makes modify hardware circuit more easily. So combined with use of software, the module is applied for multimedia control device or other front-end equipment in video monitor.
