Vehicle Anti-theft System Based GPS And GPRS Technology

With the development of satellite navigation technology and communicationstechnology, set the GPRS(General Packet Radio Service) mobile communicationtechnology and GPS(Global Positioning System) satellite positioning technology inone study of car alarm systems has become a hot, access to the vehicle of locationinformation by GPS location information via GPRS to the vehicle owner:①ownercan to determine whether the vehicle is stolen by change of the location of the vehicle(stolen alarm signal sent to the owner);②owners of stolen vehicles at any timewhere you can get directions, is conducive to public security work.. Based on this, thedesign of GPS as a positioning means, GPRS as the wireless means of communication,has developed an embedded platform based on ARM-linux car alarm systems.The design of the first anti-theft system for vehicle navigation and research anddevelopment at home and abroad are analyzed in-depth study of GPS, GPRS,embedded systems and other related basic theory. Then proposed based onARM-linux embedded platform car alarm system’s overall design, complete systemhardware platform design, including power supply module, clock module, reset thechip configuration, SDRAM memory design, Nand Flash design, UART（UniversalAsynchronous Receiver/Transmitte）, JTAG（Joint Test Action Group）, GPS, GPRSand SIM card module interface circuit design. Linux operating system developmentwith the characteristics of the completion of the linux kernel configuration,compilation, transplantation, bootloader configuration, migration, and the root filesystem of production and transplantation, and complete the relevant hardware kerneldrivers and system applications for editing, compiling and transplantation. Finally, thesystem was debugged and tested, and further improve the system made someimprovements...
