Adelaide-based startup Ping was awarded a $170,000 Australian Government Accelerating Commercialisation grant last week to help trial, upscale, connect and launch its device on domestic and international markets after six years in research and development.
The Ping Monitor is a world-first application of aero-acoustic analysis to help continually detect wind turbine blade damage.
It has the potential to replace or reduce drones and maintenance crews that routinely inspect wind turbines, sometimes long after a problem has occurred.
An initial, portable Ping Monitor was launched in September 2018 but a new solar-powered version that is fixed magnetically to the turbine pole about two-metres above ground or sits off the ground alongside the turbine will soon be launched.

The 2.0 version will also benefit from a collaboration between Ping and South Australian IoT satellite communications company Myriota, enabling the acoustic monitor to transmit data into the cloud from almost anywhere on Earth regardless of cellular network connectivity.
There are about 400,000 active wind turbines in the world with blades up to 80-metres long that spin up to 300km/h.
Ping chief executive officer Matthew Stead said pilot trials of the updated monitor are being conducted in Australia, the United States and follow extensive version-one trials last year that tested analytics and fault detection algorithms.
He said the South Australian company had already generated interest among a number of local investors.
“What we are doing is dramatically different, it’s continuous sound wave monitoring so it’s definitely exciting times. It’s going to be a big year.
“We’re calling this an ‘intelligent listening platform’ and what we mean by that is our device can be applied to a whole range of scenarios such as surveillance, listening for aircraft or drones you don’t want to be there and monitoring for the presence of predators such as wild dogs on farms.”
The key piece of technology in the patented device is the algorithm that can rate the health of the turbine based on its acoustic signature on a scale of one to five and monitor changes over time.
Stead said there were 3800 blade failures globally per year causing up to $5 billion damage.
He said sources of damage included lightning strikes, hail, sand, rain, wind and accelerated wear in coastal environments.
“We’ve seen some sites where they’ve got damage that they didn’t know about for a year or another site hadn’t been inspected for three years — you don’t really want the damage getting worse over time,” Stead said.
Fellow South Australian startup Myriota has been scaling up since it was spun out of the University of South Australia in 2015 and last year raised $19.4 million through a Series A funding round, with Boeing HorizonX Ventures among the contributors.
It launched its fourth next generation nanosatellite on Spaceflight’s SmallSat Express mission aboard Falcon 9 in December.
Myriota last month announced a collaboration with another Australian company to connect mass-market water-level sensors to its low-cost earth-to-satellite transmission technology, enabling farmers to receive water-level data direct to their mobile phones.
