Design And Implementation Of Multi Board System In Intelligent Writing Display

With the use of intelligent writing display system developed by our school in the middle and elementary schools and research institutes,the system is functional and practical that easy to operate,and has been widely praised by teachers and research workers.However,with the promotion of products,there have appeared some larger teaching spaces(such as university ladder classrooms,with large space and large numbers of people),as the screen of the single-board system is too small,the display capacity is limited,and the products cannot meet the requirements of large space classroom teaching.Therefore,the use of split-screen technology,the design of blackboard content or linear electronic data through a multi-screen orderly display,has great significance for product promotion.This article mainly elaborates the purpose and significance of the smart writing display multi-board system research.The intelligent writing shows that the multi-board system is not simply an increase in the number of screens from hardware and software.In the actual design,the hardware needs to consider the layout of the external liquid crystal display,and at the same time,the high-definition signal in the touch machine is transmitted to the display through the matrix splicer;The system functions include orderly display of screen contents and orderly switching between different screens.In terms of the software function design of the multi-board system,the overall multi-screen function is achieved through the split-screen technology on the basis of expanding multi-screen hardware,and on the basis of maintaining the basic functions of the original smart writing system,according to the actual application of the system.The problems that emerged and the effective suggestions put forward by the users of the products were improved.The problem of the non-smoothness of the curve appearing in the specific curve drawing was emphasized.The use of cubic spline interpolation algorithm to improve,so that the curve drawn in the system is more smooth.At the same time,the new function of physical booths can be added to facilitate the display of paper materials and physical objects needed for teaching,which can be used by teachers to explain in class.Intelligent writing shows the remaining main functions of the multi-board system to maintain the original smart writing system design ideas,according to the actual needs of the multi-board system,design and implementation.There are three boards,four boards and five boards in the multi-board system...This paper only introduces the intelligent five-board system that is used in large-scale classrooms.
