LabVIEW Human-Machine Interface

The LabVIEW HMI provides direct system control through an interactive P&ID schematic, enabling operators to visualize and command valves, sensors, and safety interlocks intuitively. Its architecture follows a fail-safe design paradigm with layered error handling, watchdog sanity checks, and a producer-consumer messaging pattern for deterministic data flow. The interface supports both single and multi-operator workflows within the same executable, preventing resource conflicts while maintaining synchronized state. A modern, high-contrast user interface improves usability in bright outdoor launch conditions and promotes rapid operator familiarity.

Robust Mission Logging Platform

The logging subsystem records selected parameters and system states either at fixed intervals or immediately upon reception for event-driven fidelity. It runs in an isolated execution context so that logging faults never block primary control functions. All errors are trapped, classified, and reported non-blocking, allowing mission operations to continue while preserving diagnostic detail. Structured log outputs facilitate post-test performance analysis, anomaly investigation, and traceability of command sequences.

Reliability & Safety Features (Summary)

• Watchdog timers supervise critical loops and trigger safe states on timeout.
• Segregated producer (acquisition) and consumer (UI / logging) loops prevent UI stalls from impacting data capture.
• Graceful degradation ensures partial functionality if non-critical modules fault.
• Configuration profiles enable rapid re-tasking between cold-flow and hot-fire procedures.

Roadmap (Planned Enhancements)

• Integrated replay mode for post-test timeline reconstruction.
• Automated test script runner with parameter templating.
• WebSocket telemetry bridge for remote dashboard mirroring.
• Inline calibration assistant for pressure and load cell channels.
