【摘要】：数字告示系统(俗称广告机或数字标牌)具有图片、字幕、音视频播放功能，相比传统户外广告形式，其具有广告内容无上限、内容更新方便快捷、听视觉冲击力强等优点。然而，由于网络的复杂性，很难对分布于网络各处的广告机进行统一管理，现阶段的户外广告机多以单机版为主，也出现了基于局域网的数字标牌系统。如何有效管理分布于城市各个角落的广告机，构建基于互联网的平台级别的规模化应用成为数字告示系统急需解决的难题。 本文通过研究现有网络通信，针对数字告示系统的特殊需求，提出了一种基于内网设备互联的方案，设计了数字告示系统中用户、广告机和服务器三者之间的通信协议，实现了用户对内网设备的实时监控管理，并使用Java开发语言编写了基于此通信协议的数字告示系统通信服务器，验证了通信协议的可用性和可靠性。同时，为了解决大规模用户和广告机并发访问通信服务器，在服务端引入了集群技术，，扩展了服务器的可伸缩性。 本文实现的数字告示系统通信子系统，投入使用后有效的满足了用户对通信的需求，得到了企业的认可。论文中设计的基于XML （eXtensibleMarkup Language，可扩展标记语言）内网设备互联通信协议具有开放性、灵活性和可扩展性等优点，能够方便的为将来的应用进行扩展。在通信服务器端引入的集群技术提升了整个服务端的可伸缩性。
[Abstract]:Digital notice system (commonly known as advertising machine or digital sign) has the functions of picture, subtitle, audio and video playing. Compared with the traditional outdoor advertising form, it has the advantages of unlimited advertising content, convenient content updating, strong visual impact and so on. However, because of the complexity of the network, it is difficult to unify the management of the advertising machines distributed throughout the network. At this stage, most of the outdoor advertising machines are mainly single-machine version, and the digital signage system based on local area network (LAN) has also appeared. How to effectively manage the advertisement machines distributed in every corner of the city and construct the large-scale application of the platform level based on the Internet has become a difficult problem that the digital notice system needs to solve urgently. By studying the existing network communication, aiming at the special demand of the digital notice system, this paper proposes a scheme based on the interconnection of the intranet equipment, and designs the communication protocol between the user, the advertisement machine and the server in the digital notice system. The real-time monitoring and management of the intranet equipment is realized, and the communication server of the digital notice system based on the communication protocol is written with Java development language, which verifies the availability and reliability of the communication protocol. At the same time, in order to solve the problem of concurrent access to communication servers by large scale users and advertisers, cluster technology is introduced on the server side, which extends the scalability of the server. The communication subsystem of digital notice system realized in this paper, after put into use, effectively meets the user's demand for communication, and has been recognized by the enterprise. The protocol designed in this paper is based on XML (eXtensibleMarkup Language, (extensible markup language), which has the advantages of openness, flexibility and extensibility, and can be easily extended for future applications. The cluster technology introduced on the communication server side improves the scalability of the whole server.
