The Design And Realization Of Information Interaction And Display System Based On NFC Technology

With the in-depth application of artificial intelligence,big data analysis,cloud computing,5G and other emerging technologies in the digital advertising industry,the survival form,communication form and product form of the digital advertising industry are undergoing tremendous changes.However,the new form of advertising has not improved significantly in the way of interaction with users.Especially in some reachable advertising media(such as: elevator advertising,public transport subway station television advertising,window,shopping mall advertising,etc.),often also need users through the tedious active search to get the corresponding information,this complex interactive mode between advertising and users erected a high wall of information,limiting the spread and development of digital advertising.NFC(Near Field Communication)technology as a very safe and efficient way of communication,its efficient information transmission ability provides many conveniences for people ' s daily life,but the NFC application mode is relatively simple,mainly realizes the simple information interaction between the two NFC modules and has not been widely used in the advertising industry.Based on the above problems,the laboratory team designed and implemented a set of information interaction system combined with software and hardware,namely,cloud-touch interaction system,which includes NFC intelligent screen,cloud-touch interaction software system and We Chat mini program.It realizes the real-time detection of the display content in the NFC intelligent screen and the location information of the goods in the screen and realizes the accurate and fast information transmission relying on the mobile terminal with NFC function.This paper focuses on the design and implementation of cloud touch interaction system at the software level.This paper uses the excellent cross-platform solution Electron,combined with the frontend application developed by React.js to create a cross-platform desktop application.Firstly,multiple functional modules are designed and implemented to cover different application scenarios and enrich the forms of digital advertising.Secondly,the real-time serial communication function is realized,and the screen display information relates to the NFC hardware module to realize the function of NFC positioning and content recognition.Then,based on Fastify,node,Mongo DB and other technologies,the back-end service of the system is built,and the software service is deployed in the cloud server by Docker,Nginx,and other technologies,creating a complete software service environment for the whole system.Finally,YOLO(You only look once)is used as the target detection algorithm to preprocess the images in the project,which reduces the difficulty of content labeling by operators and optimizes the interactive experience of the system.In this paper,the main innovations in business design and function implementation are as follows:Functional innovation: A new interactive mode based on NFC is proposed.NFC is modularized,and the function design of plane positioning and information transmission is realized with software algorithm.Innovation of the implementation scheme: on the one hand,a cross-platform desktop application is created through Electron technology and front-end application developed with React.js.Combined with serial communication function,hardware writing protocol is customized.On the other hand,the target detection algorithm is introduced into the Web front-end project,and the YOLO algorithm is used to preprocess the images in the project to identify and locate the key information in the images.Innovation in the application field: the combination of the plane positioning technology of the designed interactive mode with the digital advertising industry expands the information interaction mode in the application field of digital advertising.
