Abstract:According to the actual demands of the development of vehicle weapon system , an vehicle comprehensive information processing platform based on the VPX standard is designed. This system has powerful data processing and exchange capacity,which uses the Rapid IO Bus and the Ethernet Bus to transfer the different types and the different amounts of system data with the classified ways. This system has characteristics of high time-limited, high reliability, high generality and high scalability. It will be the trend and the direction of the new vehicle comprehensive information processing system.
