A GPS/GPRS System Of Vehicles

Global Positioning System of vehicles , also known as auto vehicles locating system , is researched starting off in 1960s . The propose of study is to find a solution for the heavy traffic issues in big cities that cause by the civilization of automobiles . Nowadays , auto vehicles locating is compose of Global Positioning System , wireless communication and Global geographical System . It is not only the essential part of intelligent transportation system , but also providing grand against theft , grand against highjack , medical emergence and so forth . However, the communication part of auto vehicles locating is based on GSM-SMS which can not offer real-time applications . The bearing of GPS of automobile's development is using GPRS technology that has high speed of 171.2 kbps to change the GSM part .After that the Global Positioning System of vehicles will offer real-time application.Through hard work of study on GPRS communication system , the author proposes a whole solution of Global Positioning System of vehicles that depended on the GPRS technology . The project uses the ARM embedded hardware platform and uClinux Operation System which has abundant resource that help building the protocol stack from hardware driver, logical link control, network transportation to operation applications . The whole solution for the auto vehicles locating system can be used in real-time position . There is detail description about the project in this paper. The product designed by the method in the paper works well in experimentation.
