Abstract Time triggered Network communication technology has been applied to the China’s next generation multi-purpose complex Aerospace Vehicle. This vehicle is based on the technology in the system satisfy safety critical communication need, and can also take into account other large amount of data of low priority communication tasks. In this paper, combined with the actual characteristics of aerospace vehicle’s mission requirements, according to the study of the key security information system level scheduling method based on this technology, a global optimal requirement decomposition and message scheduling algorithm based on automatic planning is proposed. The automatic generation algorithm of message scheduling table according to the system message transmission needs, and to meet the needs of key safety messages in the table does not meet the labeling and suggestions, providing the basis for the design of aircraft overall communication timing and strategy. Matlab/Simulink is used to modeling, simulating and verifying the algorithm. The simulation results meet the requirements of the communication design of the aircraft system.
