Research Of The Key Technology Of Audio Service Cloud Server Based Onvehicle Networking

In recent years, along with the improvementof the society and the people’s living standard, city’s traffic net is growing faster and faster. The level of users’ demand of multimedia terminal equipment is also become higher and higher. And the amount of these demands is also growing, the concept of the Internet of things is also constantly being improved. Hence, the attention and research of vehicle network is becoming bigger and bigger. Under this background, this thesis research, design and complete a vehicle network software multimedia equipment which is based on a new generation of high-performance embedded platform, embedded operating system, and new high-speed communication technologies. Mainly discussion is focusd on the server part of this system.The thesis introduce and analyze the background of the whole project, includingthe introduction of car networking development in recent years, and overview summary of major well designed products. Then make a choice of the file-transmission pattern and analyze the key technologies of the server. Departed by function, the server this thesis designed contains four part s: the Internent connection, the response for the clients’ request, concurrent programming and database. The workflow is this: first the client and the server are connected successfully, then the server respond the client ’s request, based on the file-transmission and the use of databases. Server achieve the function of respond multiple clients at the same time by using the technique of concurrent programming.Base on the discussion of the server’s four functional parts, this thesis complete the design and realization of the full architecture of the server, and mainly discuess the complete of some main techniques, such as multi-threaded programming model, and My SQL database and so on. The thesis comes up with the points which can be be approved of theserver’s architecture.
