Research on Internet of Vehicles Gateway based on RTSJ

Abstract

In order to promote the integration of automobile network and Internet, Internet of Vehicles gateway plays an important role in connecting vehicle-borne network and Internet. In view of the current developers using traditional development methods to achieve Internet of Vehicles gateway software, a new implementation scheme -- real-time Java technology is introduced. This paper takes the AMD Opteron 1150 processor based on the ARM Cortex-A57 architecture as the core to build the hardware platform of the Internet of Vehicles gateway, and gives the overall structure diagram and hardware connection scheme of the Internet of Vehicles system. The gateway adopts the networking scheme of "4G+ sensor network technology/field bus" and realizes wireless data interaction on the basis of real-time operating system. In addition, the data communication of Internet of Vehicles (three-layer communication structure) is realized on the WebSphere Real Time development platform that is fully compatible with RTSJ, so as to realize data sharing between the automobile bus network and the Internet. Finally, the implementation technology and system verification of the design are given.
