【摘要】：數(shù)字告示系統(tǒng)(俗稱(chēng)廣告機(jī)或數(shù)字標(biāo)牌)具有圖片、字幕、音視頻播放功能，相比傳統(tǒng)戶外廣告形式，其具有廣告內(nèi)容無(wú)上限、內(nèi)容更新方便快捷、聽(tīng)視覺(jué)沖擊力強(qiáng)等優(yōu)點(diǎn)。然而，由于網(wǎng)絡(luò)的復(fù)雜性，很難對(duì)分布于網(wǎng)絡(luò)各處的廣告機(jī)進(jìn)行統(tǒng)一管理，現(xiàn)階段的戶外廣告機(jī)多以單機(jī)版為主，也出現(xiàn)了基于局域網(wǎng)的數(shù)字標(biāo)牌系統(tǒng)。如何有效管理分布于城市各個(gè)角落的廣告機(jī)，構(gòu)建基于互聯(lián)網(wǎng)的平臺(tái)級(jí)別的規(guī)�；瘧�(yīng)用成為數(shù)字告示系統(tǒng)急需解決的難題。 本文通過(guò)研究現(xiàn)有網(wǎng)絡(luò)通信，針對(duì)數(shù)字告示系統(tǒng)的特殊需求，提出了一種基于內(nèi)網(wǎng)設(shè)備互聯(lián)的方案，設(shè)計(jì)了數(shù)字告示系統(tǒng)中用戶、廣告機(jī)和服務(wù)器三者之間的通信協(xié)議，實(shí)現(xiàn)了用戶對(duì)內(nèi)網(wǎng)設(shè)備的實(shí)時(shí)監(jiān)控管理，并使用Java開(kāi)發(fā)語(yǔ)言編寫(xiě)了基于此通信協(xié)議的數(shù)字告示系統(tǒng)通信服務(wù)器，驗(yàn)證了通信協(xié)議的可用性和可靠性。同時(shí)，為了解決大規(guī)模用戶和廣告機(jī)并發(fā)訪問(wèn)通信服務(wù)器，在服務(wù)端引入了集群技術(shù)，，擴(kuò)展了服務(wù)器的可伸縮性。 本文實(shí)現(xiàn)的數(shù)字告示系統(tǒng)通信子系統(tǒng)，投入使用后有效的滿足了用戶對(duì)通信的需求，得到了企業(yè)的認(rèn)可。論文中設(shè)計(jì)的基于XML （eXtensibleMarkup Language，可擴(kuò)展標(biāo)記語(yǔ)言）內(nèi)網(wǎng)設(shè)備互聯(lián)通信協(xié)議具有開(kāi)放性、靈活性和可擴(kuò)展性等優(yōu)點(diǎn)，能夠方便的為將來(lái)的應(yīng)用進(jìn)行擴(kuò)展。在通信服務(wù)器端引入的集群技術(shù)提升了整個(gè)服務(wù)端的可伸縮性。
[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.
