| Abstract: | In some airborne communication system,data exchange between different airborne devices was realized by using CAN2.0B(Controller Area Network) protocol to minimize complexity of electric connection and improve reliability and real-time performance.The message format assignment,transmission of large amount of data and data exchange mechanism were also introduced in detail.Finally,an application example was proposed to confirm the feasibility of the proposed protocol design. |
