Design And Verification Of Digital Avionics Full Mission Simulatior System Architecture

Avionics system is considered to be one of the most important and complex system for the flight, and it is also one of the signs of advanced aircraft. It provides radar, communications, navigation, electronic warfare, task processing, display and control functions. With the development of simulation technology, simulation has become an effective tool for the research and development of avionics system. By carrying out the relevant simulation experiments, the development period and the cost can be greatly shortened. And the avionics simulation at present is for a special equipment, different equipment use different special simulator.In this thesis, the concept of FMS(Mission Simulator Full) is proposed, which is based on the full understanding of the structure and the existing problems of the avionics simulation system. Based on the relevant literature refer to a large number of existing avionics simulation system and the Technology of system structure, the design of the FMS system architecture based on DoDAF(DoD Architecture) is deeply studied. The main research contents include:On the basis of studying the structure and development of avionics system, the concept of Avionics Full mission simulation system and its features and advantages are presented. The architecture design of the avionics system is supported by the Architecture Technology.According to the design requirements of FMS system, first has carried on the requirement analysis and system indicators setting. Secondly, taking the typical reconnaissance attack task as an example, the detailed analysis is carried out from three aspects: task, function and system. Finally, the design of the FMS task management subsystem is completed.Methods and tools for DoDAF and Architecture Technology were studied. The FMS architecture of the scout-attack mission is designed in the DoDAF Rhapsody platform. It includes the creation of the running view product, the creation of the system view product, and the model of the task management executable model. And the simulation verifies the logic feasibility of its architecture, and proves that the design is feasible.According to the function and performance demand, combined with the FMS system architecture design, from the aspect of network architecture, versatility, software architecture and implementation, completed the summary design of hardware and software of the open real-time simulation platform. And the architecture was evaluated from real-time and reconfigurable.
