STS crane rotating equipment condition monitoring

Anomalies in crane drivetrain signals that change with operating state and load, watched continuously.

Project overview

Site

Target
Drivetrain rotating equipment
Data
Sound, vibration, temperature, PLC state, speed and load
Objective
Continuous drivetrain anomaly monitoring in operating context
Client
Major Korean port operator
Duration
Field deployment

Field problem

STS crane drivetrain sound and vibration vary with operating state and load, so scheduled inspections cannot track every change during operation. Analyzing sound or vibration separately can misclassify normal state transitions as anomalies.

XyloZero deployment

Field hardware collects acoustic, vibration, and temperature signals around the drivetrain and aligns them in time with PLC operating state, speed, and load. The system selects data at the edge, sends it to the API, manages per-device sessions and history, and identifies anomalies in operating context.

  • Sound, vibration and temperature sensor nodes installed around the drivetrain
  • Signals aligned in time with PLC operating state, speed and load
  • Edge-selected data sent to the API with per-device sessions and history

Analysis

  1. Hoist, trolley and brake state and load used as operating context
  2. Normal operating sound separated from anomalous signals by operating interval
  3. Anomaly events delivered with their raw signal and context

Results

  • Continuous drivetrain condition and anomaly monitoring
  • Separation of normal operating sounds from anomalous signals
  • Unified management of live data and historical sessions by device
  • Source signals reviewed with their operating context
