An Integrated Architecture Design Method for Multi-platform Avionics System

The mission environment presents the trend of systematization, informatization, and strong confrontation in the future, and the mission style also develops from ‘single’ to ‘cluster’. With the development of unmanned system, the unmanned unit will play an increasingly important role in the process of mission execution. The mission execution mode with the collaboration of different kinds of platforms can form an organic system through mutual support and complementary ability. Therefore, it is necessary to launch the research on the architecture design of multi-platform avionics systems for multi-platform collaboration so as to define the interface pattern among different platforms. Firstly, this paper proposes a multi-platform avionics integration method and architecture drawing lessons from the idea of system integration inside the single platform to support task integration for different missions, system function integration for different capabilities, and system resource integration for different aircraft platforms; Then, this paper proposes a collaborative simulation and verification method based on the scenario design tool and the system modeling tool. By constructing the consistency environment of scenario space–time domain and architecture logic domain, the rationality and accuracy of the simulation model are improved. Finally, the comparative analysis between the multi-platform architecture proposed in this paper and the traditional architecture is realized by analyzing the spatial and temporal data of the collaborative simulation model. The superiority of the proposed multi-platform avionics architecture is verified.
