| With the development of science and technology,communication technology andterminal equipments areconstantly developing.Mobile phones have become an indispensable part of people's daily life,so people want phones to do more jobs for them.This stimulatesa series of short-range wireless communication technology's development.In all of them,near field communication(NFC)technology gets the favour of some research institutions and manufacturers because of its fast connection,fast response and low cost.This pager realizesthe NFC information transmission system bases onthe NFC technology.The system's main features are showed as follows;First of all,the system will classify the information befor the information transmission,for different sizes of data,using different strategies.Secondly,the system combines NFC technology and other wireless transmission technology,such as bluetooth;when some large information data need to be transferred,only in this way can we improve the transmission rate;Thirdly,this system can automatically create communication link and match thebluetooth module.The overall structure of the paper is divided into six chapters.The first chapter outlines the research background and the current situation of NFC,puts forward the research content and the overall structure of the paper;In the second chapter,the Android technology which is necessary for the realization of the transmission system is analyzed deeply;In the third chapter,this page analyses the demand on this system,put forward the overall framework of the system and its structure model,gives the system data flow diagram and divided module system;The fourth chapter detailed system module diagram,the design of the system sequence diagram and class diagram and achieve the whole system module by module.In the fifth chapter,the function and performance of the system are tested,and the availability of the system is proved;The sixth chapter summarizes the work of this paper and the prospect of the next step. |
