Research And Development Of Portable Search System Of Bus Based On Embedded ARM-Linux

With the daily increased demand of embedded product, the embedded system also becomes increasingly complex. Nowdays in this world there are lots of excellent embedded systems such as Vmworks Wince Symbian and so on.but there is the same feature which is the high price and the keeping secret of the code.that will compel the Company of our contury face the hardship. Linux become very popular becauseLinux have the features which are free high efficiency.This paper has done a deeply research with the search system of bus base on arm-linux in detail. The system chooses the high-qualified 32 bit Mini2440 platform of the S3C2440 processor which are produced by the Samsung and based on the Arm920t microarchitecture core, as an embedded developing platform. Firstly, the system chooses the embedded Linux as the operating system on the developing platform. It makes full use of the outstanding calculating ability and the various interface equipments provided by the Mini2440 platform, and then finished the design and realization of the search system of bus in the embedded Linux, Secondly, there is a transplantation of Qt embedded 2.3.7 in Linux. And we also develop the graphical user interface based on Qt/embedded.The practical application shows that the bus system can meet the need of design. If we make a deeper development of this system, we may apply it in such an informationalized and digitized situation as the urban digital transportation so as to have this subject own a broader market prospect and utilizing value.
