Flight Track Data Transmission and Visualization System Based on OpenGL and AFDX

To detect and observe the processing results of flight track data by embedded systems, this paper presents a flight track data transmission and visualization system based on Open Graphics Library (OpenGL) and Avionics Full Duplex Switched Ethernet (AFDX). We first realize the visualization of flight scenes, design a 3D flight track generation program, and dynamically simulate multiple aircraft tracks, which serve as a data source for the embedded processor. Integrated interconnection of host and embedded processor is carried out using AFDX, aircraft track data source is sent through virtual links, and result data processed by embedded is received simultaneously. The host application program is developed for data processing such as collision detection in protected airspace, and the running results of embedded programs are superimposed and displayed, to realize the three-dimensional visualization of flight tracks in the airspace of the flight scene. The simulation and the joint test indicated that the system performed well and successfully transmitted data between the host and the embedded processor. The system is capable of showing the processing results of 3D track data by plotting 3D track curves and providing great assistance in developing integrated modular avionics embedded systems.
