RotorPulse

RotorPulse: HVAC Plant Health Drift

Pilot vibration-drift evidence for building equipment; not failure prediction or maintenance authority.

Readiness Shared-family mapped

Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.

Evidence Strong theory Supported hypothesis

Published physics or adjacent results support the hypothesis; capability-specific product and site validation are still required.

Runtime family Machine vibration

Spectral energy and drift tracking for repeatable machine vibration signatures.

When no ESP32 is connected

No compatible ESP32 stream is connected. Use the bundled Buildings recording; it demonstrates the shared Machine vibration runtime, not independent proof of this capability.

Intended capability

Pilot this intended outcome through the shared Machine vibration family, then validate it against site-specific ground truth: Predictive maintenance for AHU fans, pumps and compressors in mechanical rooms: bearing wear, belt slap, and mounting looseness show up as drifting vibration signatures weeks before failure.

This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

Solution blueprint

See the environment before installing it.

This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording

A related Buildings scene

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.

01 The physics

Rotating machinery imposes stable, narrowband micro-Doppler tones (shaft rate + harmonics + blade-pass frequency) on reflected paths; bearing degradation adds sidebands and broadband energy, belt problems add sub-harmonics. Signature drift is mechanical degradation, not environment.

02 Shared processing path

Micro-Doppler feature extraction (machine-vs-human already proven) -> adaptive PCA per-machine signature manifold with rolling baseline -> compartment Kalman + CUSUM on harmonic amplitudes/sideband energy over weeks (119-day drift control proves the long-baseline stability needed).

This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.

03 Validation plan

CSI-Bench machine-activity subsets for signature separability; own-hardware: ESP32 pair aimed at an AHU, induce imbalance with a clip-on mass and belt-tension changes, verify CUSUM detection lead time vs accelerometer ground truth.

04 Commercial hypothesis

For the O&M contractor: 'Vibration-analyst coverage of every fan and pump in the building for the cost of one accelerometer — failures announce themselves three weeks early over WiFi.'
