This paper introduces the network composition, topology and communication principle of time trigger protocol bus. The characteristics of event-triggered and time-triggered protocol bus are compared and analyzed. The bus transmission requirements for high security, high reliability, real-time, fault tolerance, resource reconstruction and time certainty in the field of avionics are analyzed. The application of time-triggered protocol bus in avionics is discussed in detail from the aspects of avionics node connection, electronic module structure, protocol layering, time determination access and state management.
