摘要

针对目前国内市场上基于局域网或者485总线的多异步LED显示屏管理系统存在的屏幕分布地理范围受限、布线成本高昂、用户只能本地操作、一个系统只能管理一种业务等问题，设计并实现了一种基于互联网技术的开放式多业务多用户多屏幕集群管理系统。系统基于Internet网络设计了一个数据中转服务器和一个媒体服务器作为用户和异步LED显示屏之间通信的桥梁，并在数据中转服务器上对客户公司、用户、屏幕及其关联关系的信息维护搭建了关系数据库，同时设计了一套可扩展的分层通信协议，并给出了一种高性能的中转服务器实现方法，还设计了客户端和异步终端软件的可复用架构。经过测试系统能够稳定高效运行，实现了多用户在任意可接入互联网的地理位置对多块异步LED显示屏进行远程实时控制。

Abstract

For the current domestic market

most of multiple asynchronous LED display management system based on LAN or 485 bus technology have many problems such as screen limited distribution geographical scope

costly cabling

localized user operations

single project managed and so on.To solve these problems

an open multiple-project multiple-users multiple-screen cluster management system based on Internet technology is designed and implemented in this paper.In the system

a data relay server and a media are designed as a bridge of communication between user and asynchronous LED display on Internet

a relational database is built to maintain the information of client companies

users

LED screens and associated relationships between them on data relay server

and a set of scalable layered communication protocol is designed.This system provides a highly optimized implementation method for data relay server. Otherwise

a reusable architecture of client software and asynchronous terminal software are designed. After testing

system can operate stably and efficiently

achieve the ability that multiple-user can control the remote multiple-asynchronous LED display in real-time at any location that can access the Internet.
