Abstract


In recent years, the rapid development of embedded systems increasingly widespread application of GPS. Handheld navigation devices more and more civilians, and has become a popular direction in the development of embedded systems. The extensive GPS application not only to the people's production and life has brought great convenience, but also has created a great deal of economic benefits to the community. Visually impaired people is difficult to enjoy normal - kind of navigation services, whether domestic or foreign, more mature navigation products are basically focused on positioning and navigation for the normal user direction. Current GPS boom driven embedded systems, low power consumption, small size, and scalability, the research and development of the visually impaired have some applicability embedded GPS positioning and navigation system has practical significance . This paper analyzes the overview of the domestic and international satellite navigation system and GPS systems research status and trends, and the ARM11 processor as the core, the Windows CE 6.0 operating system, the design of the hardware and software development platform. Part of the overall design of the embedded GPS navigation system, specific analysis of the principle of GPS positioning hardware functional requirements of the system as well as the software framework, after the system hardware and software design. Hardware selection SAMSUNG ARM 11 processor S3C6410 as the core processor, built with the LCD display, touch screen and keyboard input and GPS module interface circuit hardware systems, analysis of each module works specific circuit design, including CPU reset circuit, LCD display circuit, Mobile DDR circuits, NAND / of NOR Flash circuit. As the operating system software, the choice of Windows CE 6.0, Windows CE system design and development methods; The research study hypergraph embedded GIS development system eSuperMap, and use its design for the hardware platform GPS positioning and navigation software. Such as key settings, navigation process improvements and targeted design, increased applicability for visually impaired users. Based Embedded GPS positioning and navigation technology research, proposed a cost-controlled, highly integrated system solutions, and the system also has great scalability, and can be adapted to the needs of a variety of GPS positioning and navigation applications reference for the future development of the GPS navigation system has a certain value.
