Design And Implementation Of Bank LED Screen Remote Information Distribution System

Most of the Bank's financial information distribution system is the stand-alone control mode, which is that all of the branches banks publish the financial information by themselves after got a notice from the main Bank. Not only lack the real-time controlling, also needs special equipment and management, increasing the Bank's operating costs.The main content of this paper is to explore the development of a Web-based Bank LED display Information Dissemination System, which break the existing restrictions of the single control mode, and achieve the centralized control of Bank financial information. It defines the implementation of the system, and designed the system network topology according to specific application environment after a detailed study and requirements analysis.The system hardware mainly use asynchronous LED display controller as the display terminal. The asynchronous display controller has memory and auto-play capability. The text and picture messages which to be published are transferred to the LED screen via the network interface. The asynchronous display controller can also reduce the load on the master computer by the way of auto play offline, further more, acheive the multi-screen network.For the system software, we main use Delphi as programming. According to the system feature, we devided the system into five major functional modules which are:information management module, screen monitor module, screen management module, rights management module, log management modules. We realize the main functions of information dissemination by the dynamic link library, to reduce the coupling relationship with other modules, make the program load faster and improve the system's stability. System disseminates the information to multiple displays by automatically obtaining the screen number functions. Remote screen control function is another major feature of this system. We achieve the host detection function to the running display using Windows Sockets API programming. Through the multi-threading mechanism to improve CPU utilization, and enhanced the screen monitor in real time. In order to facilitate the management, system manages all the screens all in a folder hierarchy, and dynamically generated the tree directory based on the level of the bank and the controlled LED screens. Since the complex structure and departments of banks, we should set the appropriate permissions to different user roles, enhancing the security of the system by dynamically generating the display menu. Through the comprehensive log management capabilities to further improve system security, and provide the appropriate basis for subsequent monitoring. The system uses the bank Intranet network to achieve network-based information publishing and remote monitoring system, which enhance the bank's financial information with real-time publish and keep consistency, saving resources expenditure, and reduce the bank costs. This is the trend of the bank information distribution system in the future and have a broad prospects for development.
