The Design And Realization Of Embedded Vehicle Terminal Based On GPS/GPRS

Recently, as development of the ITS (intelligent transportation system) and the increasing need of information service, the Vehicles Managing Navigation System that is the most important proposition of ITS also has to face more and more requirements. However, the communication part of Vehicles Managing Navigation System is based on GSM-SMS which can not offer real-time applications. The bearing of the Vehicles Managing Navigation System's development is using GPRS technology that has high speed and inexpensive expenses to change the GSM part. After that the Vehicles Managing Navigation System will offer real-time application.In order to satisfy the requirement of market, it is important to design a suit of Vehicles Managing Navigation System. Through hard work of study on GPRS communication system, the author proposes a whole solution of Vehicles Managing Navigation System that depended on the GPS/GPRS technology, and designs an embedded vehicle terminal based on ARM.The project uses the ARM embedded hardware platform andμC/OS-ⅡOperation System which has abundant resource that help designing the software of the application layer and adapter layer. The whole solution for the Vehicles Managing Navigation 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.
