The Design Of GPS Navigation System Base On Embedded System

With the National Highway Traffic building's rapid development and popularity of motor vehicles, China in highway road traffic management issues have become increasingly prominent, with roads and motor vehicle related violations increased year after year, road accidents illegal sudden increase in road traffic accidents and The occurrence of traffic police departments are made aware of the need to develop a mobile police traffic police, traffic police officers to enhance the work efficiency.Based on the analysis on the basis of the original products, according to the current technical conditions were improving. In this paper, a research and development of embedded technology, the traffic police officers to support GPRS GPS systems, and the traffic police for real-time business information, and upload illegal information collection and real-time display terminal location, and other functions, and application development simple and can meet Customized requirements.Papers described in a simple navigation system based on the S3C2410 based on the realization of the process. This article discusses in detail the design of the navigation system. Mainly on the overall design of the system, its main functions include systems, hardware design and software systems design. In the design of the hardware system using the Marvell PXA270 processor chip. And discusses in detail PXA270 processors based on the navigation system of the various functional module (application processor, memory, multimedia audio chips, LCD and power management chip) hardware design, modules are given most of the realization of circuit. In system software development process, described Windows.CE operating system-driven development model. Several key focus of the driver and the realization of transplantation, including the serial port, LCD display and power management. The actual use shows that the system practical and reliable, satisfying the actual needs.
