Embedded Automotive Network Systems Software Design

Now a days, the automobile electronic technology develops fast, the automobile network system has been one of the hottest technologies in this area. As the rapid development of the embedded system technology. The embedded-tech combined with CAN_BUS network system brings forward the concept of Embedded Automobile Network System.. Here mainly introduced the system frame and software structure design founded on the Embedded Operating System Plat, further more, based on the users' requirement analysis, completed the design of the software modules and GUI.Firstly, the paper introduced the condition of the research background and the related technologies. The traditional technology of automobile electronics could not meet the requirement of drivers, the large-scale application of CAN-BUS network would be the milestoneof automobile electronic area.Secondly, the thesis described the process of system structure and software frame design. The system made the AT91RM9200 as the processor, which had a ARM9 core, the embedded linux operating system as the software plat. The main function modules were CAN-BUS data collector module, wireless communication module and LCD display module.Thirdly, the thesis expatiated on module software design in details, including the working method and the software flow of CAN-BUS data collector module, wireless communication module and LCD display module. The protocol of CAN-BUS network and wireless communicating were all involved in it.At last, according to the result of the system, the thesis summarized the functions and the characteristics of the system, and expected for the system future application. Moreover, based on the well expansibility, the thesis planned for the following developing work.
