【摘要】：数字标牌系统是通过终端LCD显示设备与媒体播放器,在大型商场、超市、酒店大堂等人流汇聚的公共场所,发布商业、财经和娱乐信息的多媒体专业视听系统。而在智能设备高速使用的今天,对于这种特定的物理场所、特定的时间段来进行广告推送的方式,已经无法满足众多广告主的需求。智能手机、平板电脑、笔记本等移动设备的普及,已将我们从早期的互联网时代领进了一个新的移动互联网时代,屏幕与屏幕之间没有了严格的区分,完全来自于同一个信息源,屏幕之间是一种联动的关系。对多屏互动联播系统的应用研究,本论文主要是站在管理的目的上,设计了一套管理平台,实现了对LCD显示屏、智能手机、用户体验PC、LED显示屏、平板电脑屏幕的内容管控。多屏互动联播系统主要分为三个模块,分别是前端展示模块、数据通信中间件模块、以及后台管理模块。论文首先阐述了系统建设所需使用的相关技术,主要包括基于Android系统的相关技术、基于Windows系统的Asp.net技术、数据加密技术与数据库等。其后对多屏互动联播系统的三个模块进行了需求分析,详细论述了在既定需求的基础上,每个模块所需要实现的功能。之后本论文进行了系统设计方面的描述,从系统整体设计开始,阐述了系统的整个结构、简写、数据库命名及规则等,此后对系统各模块进行详细的介绍,包括各模块的框图、流程图等。在通信协议设计部分,以接口描述、示例、请求数据结构设计与响应数据结构设计的方式介绍了本系统所需使用的通信协议内容。随后本论文阐述了系统实现的相关内容,针对系统设计的三个模块,系统实现部分进行了一对一的详细描述,提供了部分软件界面或效果截图,以及部分核心源代码。最后在系统测试部分中,论文介绍了系统测试环境,包括前端测试所需使用的相关硬件与PC服务器,其中一台PC通过软件模拟多终端并发请求,通过测试用例的方式概述了主要功能的测试结果,同时在模拟多终端并发的情况下,验证了系统性能情况,通过测试结果可以看出系统设计满足预期目标情况。多屏互动联播系统通过一套管理平台,实现了对LCD显示屏、智能手机、用户体验PC、LED显示屏、平板电脑屏幕的内容发布与管控。就当前的市场调研来看,如中科大洋、星网锐捷等传统数字标牌厂商,多屏互动联播系统的研究与设计走在了数字标牌领域前沿。
[Abstract]:Digital signage system is a multimedia professional audiovisual system which distributes commercial, financial and entertainment information through terminal LCD display equipment and media player, in large shopping malls, supermarkets, hotel lobbies and other public places. However, in the high speed use of smart devices, for this specific physical place, a specific period of time to carry out advertising push, has been unable to meet the needs of many advertisers. The popularity of mobile devices such as smartphones, tablets and laptops has led us from the early Internet to a new era of mobile Internet, with no strict distinction between screens and screens. All from the same source of information, screen is a linkage between the relationship. In this paper, a management platform is designed to control the content of LCD display screen, smart phone, user experience PC,LED display screen and tablet screen. Multi-screen interactive broadcast system is mainly divided into three modules, namely front-end display module, data communication middleware module, and background management module. In this paper, the related technologies used in the construction of the system are introduced, including the related technology based on Android system, the Asp.net technology based on Windows system, the data encryption technology and database, etc. Then the requirements of the three modules of the multi-screen interactive simultaneous broadcasting system are analyzed and the functions of each module are discussed in detail on the basis of the established requirements. Then this paper describes the design of the system, starting with the overall design of the system, describes the entire structure of the system, abbreviated, database naming and rules, and then the system modules are introduced in detail, including the block diagram of each module. A flowchart, etc. In the part of communication protocol design, the communication protocol content of this system is introduced in the way of interface description, example, request data structure design and response data structure design. Then this paper describes the relevant contents of the system implementation, for the three modules of the system design, the system implementation part of the one-to-one detailed description, provide part of the software interface or effect screenshots, as well as part of the core source code. Finally, in the part of system testing, the paper introduces the system testing environment, including the related hardware and PC server used in front-end test, in which a PC simulates the concurrent request of multiple terminals by software. The test results of the main functions are summarized by means of test cases, and the system performance is verified by simulating the concurrency of multiple terminals. Through the test results, it can be seen that the system design meets the expected objective. Multi-screen interactive broadcast system through a set of management platform, achieve the LCD display screen, smart phone, user experience PC,LED display screen, tablet computer screen content distribution and control. As far as the current market research is concerned, the research and design of multi-screen interactive simultaneous broadcasting system, such as traditional digital sign makers such as Zhongke Ocean, Star net Ruijie and so on, are at the forefront of the digital signage field.
