Development and realization of embedded car networking vehicle terminal software system

摘要

Abstract As China’s economy develops vigorously, people’s living quality has been greatly improved and its car ownership has been increasing day by day. Consequently, traffic jams and safety problems become more and more severe. To solve these problems, the idea of car networking system construction has been put forward based on the improvement of Internet of Things and computer technologies. However, the vehicle terminals produced by many automobile manufacturers has disadvantages, such as incomplete functions, incompatible interface and exorbitant costs, etc. Therefore, based on the concept of car networking as well as the new 4G network technique, this study designed a kind of embedded car networking vehicle terminal and analyzed its hardware structure and installation problems. Moreover, its function of boot load program was extended and a software development platform of the embedded vehicle terminal based on Linux core was constructed. On the basis of the software and hardware environment construction, the global position system (GPS) and ZigBee wireless transmission software of the vehicle terminal were designed. In addition, the realization of the function of serial port communication was elaborated, and the development and realization of the embedded car networking vehicle terminal software system were explored.
