The Design And Implementation Of Electronic Guide System Based On ARM And Embedded GIS

The tourism industry develops very rapidly in China and becomes one of the most important industries. It plays an extremely important role in extending the internal needs, stimulating consumption, developing economy, and promoting the process of urbanization. However, the tour services and tour consultation can't follow the development of the society's needs, resulting to inconvenience of tourists during the journey. With the development of the technology, the electronic guide system combined embedded technology with embedded GIS technology can provide various services to tourists and give them convenience during the journey.This paper depends on a key plan project of Zhejiang province. The electronic guide system, developed on the basis of Open Source Software, aims to effectively reduce the price of the products and meet the needs of the society. The developer of the subject uses S3C2410 ARM of Guangzhou SIDAO as infrastructure hardware; Embedded Linux operating system as software platform; QT/Embedded GUI as graphical interfaces to transform MapInfo file format and to make it suitable for embedded system. The subject is programmed by C/C++, and develops embedded GIS module and electronic guide application software module. Then the developer combines software with hardware and displays electronic map on touch screen, which will finally carry out the functions of spots inquire and introduction, the path planning of tourism scenic area, distance measurement, GIS operation and so on.The research work of this subject is as follows: First: the transplant of Linux kernel and drive on ARM S3C2410.Second: the research and development of GIS module based on linux operation system. Third: the development of electronic guide application software using QT/Embedded GUI as graphical interfaces. Forth: the research and development of computing method of spots paths planning based on simulated annealing algorithm.Finally, the research achievement of this subject is realized in electronic guide system of Scenic Spots and Historic Sites of West Lake, and has gained desirable results.
