银行LED屏远程信息发布系统的设计与实现
|
摘要
当今银行的金融信息发布系统多以单机控制模式为主,即由主行下发通知,各分行自行控制金融信息的发布。不仅在实时性上有所欠缺,还需配置专门的设备及管理人员,增加了银行的运营成本。
本论文研究的主要内容是探索开发一套基于网络的银行LED显示屏信息发布系统,突破原有单机模式的限制,实现银行金融信息的远程发布与集中控制。经过详细的探讨和需求分析,确定系统的实现方案,并根据具体应用环境设计了系统的网络拓扑结构。
系统硬件方面,主要采用异步LED显示屏控制器作为显示终端。异步显示屏控制器具有存储及自动播放的能力,待发布的文字及图片信息通过网络接口传入LED屏,由LED屏脱机自动播放,降低了主控电脑的负荷,实现多屏联网。
系统软件方面,主要采用Delphi编程实现。根据系统特点划分了信息管理模块、屏幕监控模块、屏幕管理模块、权限管理模块、日志管理五个主要的功能模块。系统利用动态链接库DLL技术实现系统信息发布的主要功能,降低了与其它模块间的耦合关系,使程序的加载速度更快,提升了系统的稳定性。通过自动获取屏幕编号函数及建立合理的数据结构,实现对多个显示屏的信息发布。实现远程屏幕监控是本系统的另一主要功能。系统利用Windows Sockets API编程,通过主机探测函数,实时监控各显示屏的运行状态。系统采用多线程机制提高CPU利用率,增强了屏幕监控的实时性。为了便于管理,系统采用树形目录结构管理各个显示屏,根据LED显示屏所属的银行的级别动态生成树形目录。基于银行结构复杂、部门繁多的特点,对不同的用户角色设置相应的权限,动态生成显示菜单,提升了系统的安全性。系统通过建立完备的日志管理功能进一步提高系统安全性,为事后监督提供相应的依据。
本系统利用银行内部的Intranet网络,实现基于网络的LED显示屏远程信息发布与监控系统,增强了银行的金融信息发布的实时性与统一性,节约了人力物力的开支,降低了银行成本,是未来银行信息发布系统的发展趋势,有着广阔的发展前景。
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.
