OUR VIBRATION ENERGY HARVESTERS AND WIRELESS SENSOR NODES CAN BE USED TO MONITOR VALUABLE EQUIPMENT AND ASSETS ACROSS A WIDE VARIETY OF INDUSTRIES, BUT MOST COMMONLY USED IN RAIL.
We can eliminate the cost, disruption and downtime caused by the need to change batteries. Our harvesters are designed for use in demanding environments, are hazardous zone certified and operate from -40 °C to 85 °C.
We can help to achieve:
- Improvements in reliability and safety, dramatically reducing operational and maintenance costs
- Improved asset utilization as condition is monitored while assets are still in service and earning revenue
- Reduced disruption and the likelihood of costly in-service breakdowns
Our experts will ensure you receive the maximum value from our unique technology and enhanced analytics.
The real time health of your assets and the condition of the track can be delivered direct to your desktop and mobile device. From snapshots of the health of your fleet to degradation rates, from maintenance planning to condition monitoring, our experts will ensure you receive the maximum value from our unique technology and enhanced analytics.
Perpetuum’s battery-free vibration energy harvesters and wireless sensor nodes have helped many customers to make the transition from a “Fail and Fix” environment to a “Predict and Prevent” system, this has led to vast improvements in rail safety and a reductions in operating costs.
Our technology is easy and quick to install, it requires no external wiring or maintenance.
Our technology is easy and quick to install, it requires no external wiring or maintenance, there are no interactions with any existing on-train systems, meaning it is extremely safe, and because there are no moving parts (apart from the Harvester’s internal vibration), it is a fully reliable and robust solution.
The technology is on-board (not track-side), ensuring a better quality of data, reliability, and the ability to monitor track condition. Our system can act as a decision support tool for “Rough Ride” calls, reducing impact on passengers.
Continuous asset monitoring provides the operator with valuable information on the quality of assets, whether new or recently refurbished. For example, the tool can demonstrate which overhauled gearboxes are sub-normal before they fail in service. This information enables the proactive engagement with the entire supply chain.
Most freight cars have no power, so the use of our vibration energy harvester allows monitoring functions to be deployed without worrying about the problems associated with batteries.
Perpetuum supplies Vibration Energy Harvesters with high levels of power suitable not only for monitoring the wagon, but also its cargo for temperature, pressure, leakage and security.
The data can be communicated over a long range through GPRS transmissions. Alternatively, the power can be used to drive wireless networks that communicate all the data, including wheel and brake data, to the locomotive cab. GPS tracking with regular updates transmitted by GPRS is also a practical solution for tracking the progress of wagons.
As well as providing information and data on the vehicle’s assets (axle bearings, wheels, gearboxes, motors), the Remote Condition Monitoring tool also enables operators and infrastructure managers to collaborate effectively and manage the wheel rail interface in real time, taking decisions that will reduce timetable disruptions and poor ride quality for passengers.
The tool provides the user with alerts based on rate of change and levels of track health presenting information for each rail against time, distance and severity. The algorithms can differentiate between impacts and gradual degradation, so can summarise whether the impacts are predominantly vertical or lateral, meaning the track teams can better prepare for a site visit.
