Design Of Auto Audio System Base On M30626FJPGP Chip

With the development of automobile industry and the increasing need of cars, more and more people set a higher request to auto audio system. Hence , many world-renowned and national-renowned auto audio manufacturers invest a lot of manpower and material resources to exploit more advanced auto audio system to fulfill the marketing need.Auto audio system is mainly composed of control module, receiving module, adjustment module, key and display module and power module, which keep the system run steadily. The auto audio system is different from the household one, which works in more complex conditions. Therefore, more factors are considered in design. In this thesis, an auto audio system satisfying the need of common users is provided, which fulfills the request when the users listen to the radio on driving.First of all, this thesis summarizes research actualities and development orientations of domestic and foreign auto audio system, and introduces research background and origin of this subject. Through research into parameters, composition and theories of auto audio system, the integrated design plan of this system is provided.Secondly, it introduces functions and characteristics of each module in details. Parts of different modules are selected according to principles and demands of this system design. And then the particular plan of this design related to hardware circuits is provided, including relation of time series among these modules, communication and control, internal control connection and ways of realizing these hardware circuits. Also, the representative circuits of this system are analyzed in details.Finally, besides mentioned above, software part of this system is also explained simply, including the whole design flow of software and flow of other modules controlled by CPU. After completing the hardware and software design, this system is debugged, and then the system is tested according to manufacturing requirements of products.
