Research And Design Of Multimedia Classroom Remote Control System

With the development of science and technology,people desire for high efficiency of the class.the application of multimedia teaching in daily teaching has become the trend of modern education,but the traditional management of multimedia teaching don’t keep up with the pace,and now it can’t meet with the current management mode.In this paper,through the remote network control,through one to many or many to many reducing the output of human resources,and it will be more convenient for teachers and managers.from the perspective of users and managers we will think about the problem to solve the problem.We will use the modern technology to improve work efficiency.The content of this paper manily do research in the network control system of multimedia classroom in colleges.This system is mainly used to implement the network central control.The paper based on multimedia classroom in Changzhou Open University as an example.according to the actual situation and the main demand of the school,the network control system needs analysis and set goals,establish the multimedia central control system model,subdivided into two modules of hardware and software.On this basis,the hardware system of multimedia classroom and the central system of the control center are installed and debugged immediately.In order to solve these problem and consider the using of the classroom in the future,and design on system based on STC10 XX.The Selection of STC10 series microcontroller is mainly due to the production of STC single clock cycle(1T)chip。And it is a new generation of 8051 microcontroller which has high speed/low power / super anti-interference.The instruction code is fully compatible with the traditional 8051,but the speed is 8-12 times faster.The inter integrates high reliable reset circuit for high-speed communications,intelligent control,strong interference occasions.and Adds an independent baud rate generator,reduces some of the timers.On the basis of the traditional 8051,the command line speed is fully accelerated,the fastest instruction is 24 times,and the slowest instruction is 3 times Because of the advantages of many aspects of performance,we chose this series microcomputer as the core part of our whole system.Based on completing the design of system,we hope to use it in the server,through the centralizing control to achieve some basic functions,such as remote turn on or off the projection,remote turn off the power switch and so on.It is convenient for managers to turn off the projection and the power in time after the class is over.And we don’t have to close the equipment in each classroom.Just after school,on the centralizing control system to do the unified processing.This will not only extend the service life of the equipment,but also be more convenient for the management,so the output of the manger will be reduced.We can also check the using of the equipment and the time of the light bulb in the control system.If the frequency of the using in a classroom is very high,it will needs more maintence than the usual.Only in this way the damage of equipment be reduced.the fuction which make the control disabled make a reminder of the teacher.if as a result of human activities,we need to know the reason.and to decide the continue of using.we hope that on the basis of the success of the study,it can be popularized and used,which will make it more convenient for future daily teaching.It will provide convenience for teachers to teach.add add vitality to the classroom,and lighten the burden for administrators.so it can be more better for serving the education and teaching.
