Study On The Technology Of Cluster Distributed Architecture Of The Large Screen Control System Based On

With the advent of the Internet era, for large screen projection display system network is increasing day by day, the original centralized control system has been unable to fully meet the needs of users. More and more users want to control network of large screen high degree, and use more wireless terminal control convenient screen of all kinds of signals to control the large screen. According to the real demands of engineering project commissioned by the company, technology of cluster distributed architecture of the large screen control system.Display system based on user demand characteristics, screen signal for high resolution GIS map, digital signal IP streaming media network signal and the computer terminal system signal, monitoring video signal on the screen, the large amount of data, real-time ability.This paper will study with a cluster of distributed multi screen control system data exchange based on JSON technology; enhance the signal processing ability of control system, to control single point of failure and the influence to the whole screen display. At the same time, improve the traditional desktop control on the big screen of the signal source, on the big screen for flexible operation control using wireless control terminal, completed and implemented the control software interface design of Android system, give users a better operating experience effect.Specific performance requirements of users based on Project, The design of cluster communication of distributed system control and Android control system of the client are successive batch test. The test results and customer feedback shows that the design of the communication control system to achieve the correct stable cluster distributed. Android system client interface beautiful, friendly use of strong, the function is complete, in line with customer usage, has achieved the expected design goals.
