Research On Architecture Of Uav's Flight Management Computer System Based On DoDAF

UAV plays an important role in the current war. The thesis works on the flight management computer system's architecture of Reconnaissance/Attack UAV. R/A UAV has the ability of rapid re- action in the war.Firstly, the development of UAV flight management computer system (FMCS) is introduced. It point out FMCS's architecture's importance. And Architecture Framework is introduced.Secondly, FMCS's requirements analysis is done from mission,function and system level. Then, R/A UAV's flight management system based on intelligent control structure is studied. Also structure and function of key modules is studied. On this basis, a distributed fault-tolerant computer system's structure is designed for FMCS. In order to ensure the fault-tolerant capability of FMCS, the redun-dant of FMCS's subsystem and Communication Network is studied. Meanwhile, a hardware reliabil-ity model is established and verified for FMCS.Thirdly, in order to realize the design of FMCS's architecture, DoDAF Standard and related ar-chitecture design methods and architecture design tools is studied. Then, the notational support of SysML on DoDAF products is analyzed. A SysML-based FMCS's architecture design method and the relationships of the products is proposed, which combines the function-driven of structured method and object-oriented idea of UML.Finally, FMCS's architecture is designed with the Rhapsody DoDAF development platform, in-cluding the products of operational view and system view, executable model of Mission Manage-ment.Then, the design method of the architecture products is proved practical.
