Research And Software Development Of The Embedded-Based Navigation For Vehicle

Vehicle navigation is a embedded system in car, it can bring much more convenience for drivers, and supply people with kinds of advantage services. In the world, the modern vehicle navigation of research already has 30 years of history. It combines automobiles, transport, computer, communications, and systems technology, and other fields of science, it has been a large number of high-tech companies, research institutions and universities on the hot.This paper is described as "Research and software development of the embedded-based intelligent navigation for vehicle ". It is funded by the item of "automobile navigation control multimedia system" in Tianjin and Hebei province. This paper studies the following elements:1. Research on the development status of embedded systems and vehicle-navigation systems at home; Outline the concept, structure and characteristics of embedded System. According to the structural characteristics of embedded system and the design principles, a general embedded system design methodology and the key technology are given, laying the foundation for the design of vehicle navigation systems embedded below.2. In accordance with the functional requirements of embedded vehicle navigation system, the proposed program of the overall design of the system is given, and gives some of the specific hardware and software components. In this paper S3C2410 made by SAMSUNG is used as subject platform , whose processor kenel is the ARM920T processor;the double frenquency module MC35i made by SIEMENS is used as wireless communication module;and GERMIN GPS T15 receiver also made by SIEMENS is used for receiving the information of GPS.For softeware,the operation system is Windows CE,and embedded software development tools- Platform Builder and Embedded Visual C++ provided by Microsoft are used to customize the operation system and develop the application programme.3. Introduce the software development platform of embedded system - Embedded Operating System, at the same time introduce Windows CE. NET operating system used in the topic in detail. Specific topics describe in the operating system kernel customization process. Lay the foundation for the development of application procedure.4. Introduce in detail the application development navigation system and some specific procedures of positioning function, wireless communications, and other functions are given,and the experimental results also are given.
