Perception & Analysis

Escalator Motor, Gear and Chain Sound Frequency Analysis; Wear Score Calculation

Autonomous Workflow

The robot stops at the start and end of each escalator, collecting 10-second acoustic and vibration data.

AI classifies abnormal squeaking, knocking, and wear sounds by comparing motor, gearbox, and chain sounds against reference baseline.

Each escalator assigned a 'health score'; automatic service call opened with maintenance company when score drops.

Escalator shutdown recommendation transmitted to facility management when sudden breakdown risk detected; accident risks eliminated.

Operational ROI.
Strategic Decision.

EXPECTED BALANCE IMPACT

Annual $45,000 maintenance and compensation savings. ROI: 2.3x | Payback: 2.0 Years.

Reduces escalator-related customer injury incidents by 94%; decreases unplanned escalator downtime by 78%.
