Acoustic device monitors health of wind turbines

An Australian startup which developed an acoustic listening device for monitoring the health of wind turbines has raised AU$850 000 to support the commercialisation of its world-first product. Adelaide-based company Ping Services has closed a $650 000 seed fund round after securing an additional $200 000 in government funding earlier this year. The patented device, known as the Ping Monitor, uses acoustic analysis, machine learning and the Internet of Things (IoT) to continuously detect wind turbine blade damage. The key piece of technology is the algorithm that can rate the health of the turbine based on its acoustic signature and monitor changes over time. The device easily attaches to wind turbine towers and actively listens to the blades’ acoustic signature while rotating to detect blade faults such as pitting or cracks caused by lightning strikes or hail.
