Design And Implementation Of Control Management System Software For Virtual Vehicle Management Computer

In the field of airborne electronics,the vehicle management system is the core system in the aircraft platform,provide necessary for aircraft systems integrated core architecture,processing the top task of flight control system,mechanical and electrical integrated management and task management system.The vehicle management computer is the core computer of the vehicle management system,and it has the characteristic of producing the vehicle management computer has a long development cycle and high cost and the resource is restricted.But the developments and debugging of the airborne software and associated system depend on the real hardware platform,and the development and debugging can't be carried out in parallel.And the development cycle and the quality of the software has impacted.In order to solve the above problems,it is necessary to virtualize the real vehicle management computer to build a virtual vehicle management computer simulation platform.The platform is used to debug the airborne software so as to promote the software's development efficiency.In this thesis,aims at the practical demand,the simics simulation platform is used to virtualize the control and management system of the vehicle management computer in windows environment,and the vehicle management computer model is designed and developed which has the same function and structure with the real vehicle management computer.And the vehicle management computer model has the all real functions and can run the real TA,operating systems and airborne applications.The main work includes:(1)The computer system simulator technology and simics mechanism are studied,and the virtual vehicle management computer communication mechanism,the equipment model modeling mechanism,the time queue mechanism,the interruption mechanism,the storage mechanism and the synchronization mechanism are studied in detail.(2)The functional and non-functional requirements of the vehicle management computer's control management system is studied,and the structure of the virtual vehicle management computer is designed.And the equipment model of vehicle management computer control management system is designed,which includes the transplantation of the CPU core model,memory model,MV64460 bridge model andFPGA model.FPGA model includes the watchdog model,discrete/analog interface model and the synchronous interface model.And the virtual integrated test equipment model(DIF)is designed,which is used to cross-platform GDB debugging of the virtual vehicle management computer.Finally,the virtual vehicle management computer is constituted with the bus model.(3)Functional testing the equipment models of control management system for vehicle management computer to ensure the correctness of the models,and integration testing the virtual vehicle management computer combined with the bus model and the closed-loop testing of the virtual vehicle management simulation verification platform ensure the function and performance of the virtual vehicle management computer.In this thesis,researching and developing of the virtual vehicle management computer solve the shortcomings of the airborne software and the real hardware can not be developed in parallel.The virtual vehicle management computer can be used to develop and test the airborne software in advance to improve the efficiency of airborne software and associated system.The virtual vehicle management computer has some practical value in engineering.
