[Abstract]:In this paper, the synthetic test platform of aircraft test system is designed and completed for unmanned aerial vehicle, which comes from the actual engineering project. The system mainly completes the testing of the parameters and functions of the components of the unmanned aerial vehicle airborne test equipment. When the actual airborne test equipment is not online, it can simulate the function of the actual equipment and ensure the smooth progress of the test. The test rig can test the finished airborne equipment and verify the rationality and stability of the unmanned aerial vehicle manufacturing scheme. The data processing subsystem is the core subsystem of the test-bed. It mainly completes the data receiving, storing and displaying. For video data, it can complete the video surveillance through the codec. When the actual airborne equipment is not online, it can not provide the data source. Can provide data source through simulator. This paper mainly completes three aspects of work: 1. On the basis of the initial test bed, combined with the simulation technology of unmanned avionics system and the automatic test technology of the aircraft, the existing problems and unfinished parts of the existing test bed are analyzed, and the design and implementation route of this paper are summarized. The design pattern is used to upgrade the software architecture of the initial platform. On the basis of the initial test bench, according to the need of the project progress, some simulators are added to improve the function of the test bench to ensure the smooth progress of the test task. 2. The multithread design and cache scheme of the initial test bed are improved, and more stable and reliable data receiving, processing and storing software are designed to meet the requirements of the increasing number of data interfaces and processing speed of the test bed, and the data display is completed. Using the control to display the data through the pattern of graphics; 3. Using FFmpeg video decoding library, SDL pixel player realizes real-time video monitoring, and self-defined video transmission and control frame improve the communication interaction and quality control within the test-bed. After coding, the software of data processing subsystem is tested. The test results show that the software designed in this paper performs well in the comprehensive test bed system, and meets the design requirements and performance indexes. Can also achieve the objectives and requirements of the test mission, the system has been put into practical use.
