Design Of Smart Home Music Player System Based On STUN Protocol

With the rapid development of Internet,the integration of the three networks gradually accelerates the pace;the intelligent home has become the focus of Internet research for the past several years.The research of intelligent home includes many aspects: intelligent illumination,digital appliances,smart decoration and intelligent music.This paper researchesan embedded intelligent music playing system which is based on Android system home network set-top box as a server,and mobile devices as intelligent terminals,and the system is developed on the platform;This intelligent terminal can not only realize home audio timed play,but also can achieve the song's remote updates and song playback free control and change.1.At present common music player has the limitations of time and place,in the light of the existing problems,a new concept of building a intelligent home background music playing system is put forward,and a smart music player system which based on mobile terminal is designed and implemented in this study.The system is based on STUN NAT penetrating way to complete the external network mobile device and home LAN server communication,in order to achieve intelligent music playback system remote update.After the system on-line,it can be seen through the feedback effect that it has a good user experience,and it can effectively meet the needs of people that have all kinds of musical ideas.The system has a broad range of applications in the intelligent home market.2.Design of embedded intelligent music playing system software.The software system design mainly includes two parts: designing service terminal system and the application system which base on mobile terminal.The service terminal system is composed of three parts: router,network set-top box and audio equipment.The design of the service terminal system includes two aspects,the SQlite database module which stores user interaction data and the command parsing module.The mobile application consists of three parts: song-on-demand,song update,and timed configuration.Mobile terminal software APP to achieve the overall function of the UI interface design,the interface design is the use of custom Android controls which contains many features and different layout patterns to collaborate together to complete.3.The music playing system has the functions of timing playing,remote updating andmoving songs.The system makes use of the flexibility of the mobile device and the network transmission function of the network set-top box to realize the remote updating and maintenance of the home music playing system.The experimental results show the system is very good to achieve the human-computer interaction,and it is fully functional and simple to use.The system is of great help to the limitations in the whole smart music playing system.
