AvionicsDigitalTwinsは、QEMU仮想エミュレーション、ARINC 664ネットワークシミュレーション、リアルタイムテレメトリシャドウを統合し、完全な航空機アビオニクスのサイクル精度デジタルレプリカを構築して飛行中ソフトウェア異常やサイバー脅威を検知します。
AvionicsDigitalTwins Synchronized In-Flight Digital Shadow Architecture
Cycle-accurate CPU emulation, virtual data bus fabric, and discrepancy anomaly detector
Central System: Virtual Avionics Host - Cycle-Accurate Co-Simulation Core
Aviation Architecture Nodes
- Physical Aircraft Avionics Suite
- Air-to-Ground Telemetry Diode
- Cycle-Accurate Virtual LRU Cluster
- Virtual ARINC 664 Bus Fabric
- Discrepancy & Cyber Intrusion Detector
Architectural Layers & Protocol Stacks
- Instruction Set Emulation & Virtualization (QEMU Aerospace Fork / SystemC TLM-2.0): Executing unmodified aircraft binary firmware with cycle-accurate register and memory timing.
- Virtual Network & Bus Interconnect (Simulated AFDX / Virtual ARINC 429 Transceivers): Routing simulated packets between virtual LRUs with exact microsecond transmission delays and jitter.
- Parallel Digital Shadowing & Comparison (State Machine Discrepancy Comparator): Comparing physical aircraft telemetry with virtual twin outputs, flagging unintended software drift or cyber tampering.
- Post-Flight Debugging & Root-Cause Analysis (Deterministic Execution Replay / Time-Travel Debug): Allowing software engineers to step backward in time through CPU execution to pinpoint intermittent flight glitches.
Flight Telemetry Metrics: 100% (Binary Code Execution Parity) | < 1 Frame (Digital Shadow State Divergence Lag) | Time-Travel (Deterministic Microsecond Replay) | Zero Hardware (Requirement for Virtual Test Clusters)
