With more and more work technique applied in embedded system and the great improvement in semiconductor manufacturing, the EMPU(Embedded MicroProcessing Unit) has extended its application to the automobile industry. The embedded technique gives the best solution for automobile electronics and makes it possible to produce high performance terminal for cars at low cost. Nowadays, wireless data transition technology has brought great fortune for business especially for the information acquisition system, which could extend the data acquisition range and cut down the maintenance technique of vehicle supervision can guide the motor to it s destination conveniently, quickly and rightly, which is very important in increasing the transportation efficiency and energy saving. The paper from two aspects of hardware and software, and analyses the principle, and gives a detailed design. Includes hardware platform design and operating system customization transplantation, the software development platform choice and application development, etc. Hardware platform design including: in the study of the characteristics STM32 processor based on the periphery of the interface, the core of the system. According to the realization of GPRS module, data interface, and foot function, pleted the design of STM32 interface . According to the characteristics of GPS module, basic structure and external pin definition, pleted the detailed design of GPS module and STM32 processor interface design, And LCD interface, the periphery connection USART interface. Software calm mainly includes GPS information collection and analysis, GPRS munication with the monitoring center, text messaging, LCD display programs. At the end of the dissertation, a summary was made. For example, It can be 摘 要 III used for electronic map and the method of bining obtain more accurate and detailed data, provide more convenient service and better map visual effect. This intelligent vehicle terminal has pact structure and powerful function such as car location and tracking. The system was economical and easily for upgrading.
