Realize maximum operational efficiency with perpetually powered wireless sensing solutions from Perpetuum.
In the industrial world, vibrations are everywhere. Perpetuum converts this otherwise lost energy into usable electrical energy for powering industrial wireless sensor nodes.
Wireless monitoring reduces the uncertainly of unmonitored asset failure and expands visibility of potential and costly points of failure within manufacturing and production environments.
This gives industrial facilities the advantages of enhanced plant visibility, manufacturing asset monitoring, reduced production disruption, and increased asset usage via intelligent maintenance scheduling. These benefits can be realized by a wide range of industrial operations including:
| · |
Oil and gas |
| · |
Chemicals |
| · |
Power generation |
| · |
Water/wastewater treatment |
| · |
Process manufacturing |
Perpetuum micro-generators present new sensing opportunities for the unique demands of transportation systems.
Rail Applications
Perpetuum's Vibration Energy Harvester is an ideal solution for providing high levels of electrical power for sensing, intelligence and communications in rail wagons.
| · |
Available vibration that generates 10's of mW of power from the harvester |
| · |
Robust design for harsh environments |
Many rail applications have different requirements, and Perpetuum products can be readily customized.
Key rail products offered by Perpetuum are:
- Rail Harvester (optimized for the vibration spectra typically seen in a rail environment) to provide a range of power outputs for customer systems.
- Rail Sensor Node (including temperature and vibration sensors) to detect wheel flats and bearing degradation.
Freight Applications
Most freight vehicles have no power, so the use of a harvester allows monitoring functions to be deployed without worrying about the problems associated with batteries.
Perpetuum supplies energy harvesters with high levels of power suitable not only for monitoring the wagon but also its cargo (temperature, pressure, leakage, security) and communicating the data 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 reality for tracking the progress of wagons.
Passenger Applications
Improvements in rail safety and significant reduction in operating costs can be achieved by moving from a "Fail & Fix" environment to "Predict & Prevent" system in which the condition of critical components are monitored for degradation to enable a potential failure to be predicted well in advance.
These transitions have been hampered by the need to hard wire sensor systems and rely on battery operation, both of which can introduce additional reliability concerns as well as cost and long deployment times.
Perpetuum's Vibration Energy Harvester solutions solve these issues by eliminating the need for batteries and enabling communication to be done wirelessly.
The advantages of Energy Harvester Powered Sensor Nodes in a rail environment are:
- Ease of installation.
- Self-contained & Self-powered: Requires no external wiring or maintenance.
- Safe: No interaction with any existing on-train systems.
- Reliable & Robust: No moving parts apart from harvester's internal vibration.
