The Design And Implementation Of Data Load Simulator Software For Civil Aircraft

With the establishment of COMAC and C919 jet project,the domestic civil aircraft development unprecedented enthusiasm,a large number of research institutes have invested in research and development of civil aircraft.The topic of this thesis is based on the development of AWCU of C919 jet information system.The AWCU is the key equipment for the high-speed data communication between the information system and the ground,and it has the function of data loading target,which means that the data loader is needed for testing this function.Through the preliminary investigation found that almost all of the airborne electronic equipment has a data loading target function,which means that the development of these devices cannot do without the data loader,and data load simulator software with data loading function is much more valuable than the data loader itself in the tests.The data load simulator software for data load target function test of avionics,not only can test the normal data loading function,can also inject a fault which is very difficult to produce during loading process to complete robustness test,in order to ensure the development of avionics whose DHL level is D or above.This thesis finished the software requirements definition through analyze the original requirements and application scenarios get through previous research,using MVC framework design the software architecture and module division,using flow chart to complete the software detailed design of each functional module;As a Windows application,the UI using MFC development,the business logic using C language development,and through static analysis,unit testing,functional testing to ensure the quality of the software.The success of the data load simulator software implementation brings the convenience to the verification of AWCU and ensure progress of the device development.We believe that the Data Loader Simulator can be used in cabin core system,communication and navigation system,and some more significant system after optimizing the Data Loader Simulator.Finally,the market monopoly of this kind software by the overseas will be broken.
