Research On Dynamic Flight Parameter Generation Technology Of Avionics Simulation And Evaluation System

In the process of the development of avionics systems, it is necessary to verify and evaluate the integration of avionics systems by using the avionics simulation and evaluation system. As the static excitation can not meets the requirement of the avionics system test in the dynamic environment, the technology of dynamic flight parameter generation is researched and the environmental dynamic control system is designed and realized. It is important to solves the problem of dynamic test of avionics systems in ground tests.Firstly, based on the specific simulation and evaluation system, the method of flight parameter generation is analysed. Recording on the developmental requirement of the environmental dynamic control system, the hierarchical open architecture design and engineering modeling program is adopted and the relationship among functional modules is sorted out.Secondly, on the basis of the aforementioned programs and research result, the design idea of oop are choosed. Dynamic control system of environment is desiged and implemented base on Visual Studio as the development environment, SQL Server and Matlab as the operating environment. Otherwise, the realization of key modules(such as graphic display module, load and playback module, console module, network communication module) and its key technologies involved(such as database technology to create a query, the recording and playback technology, data transmission technology) are introduced.Finally, it designs friendly interaction interface and applied to the process of communication and navigation airworthiness evaluation. Through the main control software and systemic interaction function are tested, The result shows that the system meets the requirement of avionics simulation and evaluation system. It provides the important data output and theory basis to the process of avionics system and development and evaluation.
