Design And Implementation Of Universal Asynchronous LED Display Centralized Management System Based On Internet

The main objective of this paper is to design and implement an openmultiple-service multiple-user multiple-asynchronous-screen cluster managementsystem based on Internet technology. For the current domestic market, most ofmultiple asynchronous LED display management system based on LAN or485bustechnology exist many problems like geographical distribution limitation, costlycabling, localized user operations, single project managed and so on. The systemdesigned in this paper better solved these problems and provide some universaldesigning methods for more aspect.The system is mainly a combination of LED display driver technology, databasemodeling, TCP network servers, computer architecture and interface, GUI programdesigning techniques and so on, and mainly to complete the following tasks:1. Analyzing user needs and the current development status of asynchronousLED display control system, putting forward the overall model of the clustermanagement system, dividing the basic components of the system software.2. Designing a scalable hierarchical communication protocol architecture basedon TCP, and establishing a multiple-service multiple-user multiple-screen relationaldatabase model, besides, developing a highly concurrent data transfer server basedasynchronous IO model as the inter-communications hub between users and screens.3. Proposing a universal screen program organization architecture and auniversal asynchronous LED screen controller hardware and softwar e features andinterface definitions, and implementing a cross-platform universal asynchronous LEDscreen player software.4. Completing the design solutions of client software and screen terminal software based on MVP architecture model, solving the problem about maximizingthe reusability of software, providing the design basis for efficient development ofnew asynchronous LED display project.
