Avionics Simulation Experiment Platform Development Based on the Optical Fiber Bus

To address the bottleneck issues of limited bandwidth and insufficient real-time performance in traditional avionics experiment platforms, this paper develops an avionics simulation experiment platform based on the FC-AE-ASM protocol. The platform utilizes a PCIe optical fiber node card (601FC10A) and an FS400 switch to construct a deterministic real-time network. Innovatively integrating three submodules—flight simulation, payload simulation, and display-control simulation—it achieves full-link avionics system simulation through six-degree-of-freedom (6-DOF) dynamic model computation, multi-target tracking and detection, and display-control system development. Adopting a "virtual-real combination" architecture, the platform supports core experiments such as FC device management, DMA communication mechanisms, and switch network configuration. Teaching practice demonstrates that the platform effectively resolves the conflict between the bandwidth limitations of traditional 1553B devices and insufficient FC teaching coverage. It enables students to master key technologies like protocol parsing and network scheduling algorithms in a high-speed optical fiber environment. By transforming advanced avionics technologies used in aircraft like the F-35 into operable teaching carriers, the platform provides a new practical teaching platform integrating industry, academia, and research for avionics-related disciplines.
