Research And Implementation Of University Multimedia Classroom Network Control System

The application of modern educational technology into the traditional teaching model modern stage, which also gives a higher multimedia technology requirements. Aiming Multimedia teaching need to optimize the integrated use of multimedia classroom management for the purpose of research and design multimedia central control system based on a single chip.Contents of this paper are of Multimedia classrooms network control system. The system is mainly used to implement multimedia classroom network central control. In this paper, multimedia control system Baoji College, for example, according to the actual situation of the school and the main demand of the network control system needs to demonstrate in order to establish goals, establish model multimedia central control systems, subdivided into two major hardware and software module, depending on the performance and teaching objectives and requirements, to build the entire system. On the basis of the control system installation and commissioning, there is a problem system and timely improvements. This paper is divided into four parts:First,multimedia central control technology development, in basic technology research carding multimedia central control proposed key technical issues and research methods need to be addressed.Secondly,the current situation of multimedia teaching, multimedia classrooms central control system design specific requirements, and describes the overall design concept and design models.Again,the microcontroller-based central control system is divided into hardware and software solutions. According hardware solution, designed microcontroller as the core hardware system, and discusses in detail the composition of each module theory and design (video, audio, VGA signal switching, curtain control, RS232 control of five modules) circuit implementation. Depending on the software program, given the host computer, the next crew of the design.Finally,in the design process multimedia central control system, the system proposed future technology development should be maintained in a remote, three aspects of online teaching and resource sharing for a breakthrough, for the optimization of multimedia systems Forward thinking.Based on the analysis of the design of the main technical performance of each module and compare multiple controllers determined on the overall structure of the module, main control module using SCM as a central control unit hardware and software design. Multimedia central control system designed in this paper by the application of each module functions to achieve the remote master control terminal constraints and classrooms in two forms. The control terminal of the control panel functions, the implementation of multimedia classroom equipment for remote control, command over a network, the remote control terminal of the control device, and then outreach to control multimedia classroom equipment in the main control room, enabling multimedia classrooms remote monitoring, remote takeover capabilities. Each classroom multimedia central controller, has a unique IP address, and the IP address of the host computer, the code will be programmed via the data written to each station controller which, thus forming a data communications network, to achieve the expected goal multimedia network control.
