Outline
The new generation of rocket-borne electrical system architecture fully embodies the characteristics of distributed information synthesis, which can realize the physical separation of rocket-borne electrical system, information sharing and dynamic resource allocation through appropriate unified real-time network design, reduce the impact of cross-domain information interaction, and improve the determinacy, reliability and fault-tolerant ability of system networking. Combined with the different real-time guarantee ability of real-time network flow control mechanisms, the information transmission requirements of rocket-borne integrated electronic system are analyzed, the time-sensitive flow control mechanisms are selected, the message and traffic type are matched, the time trigger window is designed through the joint optimization of path and scheduling, and the network simulation model is built using the OMNet++ to simulate and evaluate the performance of the network system. Through simulation, the matching relationship between all traffic and time-sensitive network flow control mechanisms in typical rocket-borne integrated electronic system are verified, and the feasibility of time-sensitive network application in rocket-borne integrated electronic system is demonstrated.
