| Digital signage system is a display device and a media player terminal through LED,in public places,large shopping malls,supermarkets,hotel lobbies and other crowded,multimedia audio-visual system,professional publishing business finance and entertainment information.In today’s high speed use of smart devices,for this particular physical location,a specific time to push the way the ad has been unable to meet the needs of many advertisers.The popularity of smart phones,tablet PCs,laptops and other mobile devices,we have ushered in a new era of mobile Internet from the early era of the internet.There is no strict distinction between the screen and the screen,completely from the same source of information,the screen is a linkage between the relationship.Research and application of the multi screen interactive network system,this paper is mainly on the management of the purpose,design a set of management platform,the realization of LCD display,intelligent mobile phone,the user experience PC,LED display,flat computer screen content control.Multi screen interactive broadcast system is mainly divided into three modules,namely,front-end display module,data communication middleware module,and background management module.First of all,the paper describes the related technologies used in the construction of the system,including the related technology based on Android system,Asp.net technology based on Windows system,data encryption technology and database.Subsequently,the demand analysis of the three modules of the multi screen interactive broadcast system was carried out,and the functions needed by each module were discussed in detail on the basis of the established requirements.This paper describes the system design,starting from the overall design of the system,describes the system’s whole structure,abbreviations and database naming and rules,then carries on the detailed introduction of system modules,including the module diagram,flow chart etc..In the design part of communication protocol,the communication protocol content is introduced in the way of interface description,example,request data structure design and response data structure design.Then this paper describes the system to achieve the relevant content,according to the three modules of the system design,system implementation part describes one of the part of the software interface provides screenshots or effect,as well as part of the core source code.Finally,in the part of system testing,this paper describes the system test environment,including front-end required for testing related hardware used with PC server,one of the PC through the software simulation of multi terminal concurrent requests,test results of the functional test case through the overview of the,at the same time in the simulation of multi terminal cases of concurrent validation the performance of the system,the test results show that the system designed to meet the expected targets.Multi screen interactive broadcast system through a set of management platform,to achieve the LCD display,smart phones,user experience,PC,LED display,tablet PC screen content control and release.The current market research,such as Dayang,Ruijie and other traditional digital signage manufacturers,research and design of multi screen interactive network system at the forefront of the field of digital signage. |
