基于互联网的异步 LED 显示屏集群管理系统的设计与实现
Design and implementation of asynchronous LED display centralized management system based on internet
摘要
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.关键词
