Design Of Digital Electronic Police System Based On Arm And Vxworks

This thesis presents the design and implementation of a cyber police system based on embedded operating system VxWorks and RISC chip S3C4510B with ARM7TDMI core. Main works are explained in four parts respectively.Firstly, a hardware platform, in which the S3C4510B provided by SAMSUNG Corporation is used as core chip is designed. The design strategy and corresponding problems solved during design, debug and implementation process are described. It has proved that this system has the following performance such as low consumption, low cost, high stability and high reliability.Secondly, the Board Support Package (BSP) for desired system, supported by WRSBCARM7 which is provided by Wind River Corporation is designed and programmed, as one of the basic parts of application process, the CPU initialization code, hardware driver and user-application software etc. are carried out. Besides the details of designed BSP, the method and procedure of the design is presented as well.Thirdly, the implementation of embedded Web Sever in cyber police system is introduced, through the web browser, not only the users, but also the developer is capable of accessing the system conveniently. Thus the developer can maintain the system, while the user can access the system anytime and anywhere.Finally, the software frame of the cyber police system is discussed, concluding task partition and the function of the back-end system, the problem of upgrading the system at long distance is discussed as well.
