The advent of Internet of Things (IoT) sensing technologies provides engineers and asset managers with condition monitoring solutions that are sophisticated and capable, yet remarkably simple to use. Wireless remote condition monitoring technologies pioneered by Senceive deliver tangible benefits relating to safety, cost-effectiveness and performance.
Rail engineers and operators have relied on Senceive remote monitoring technology since 2005. Tens of thousands of sensors are installed on track, earthworks and structures and the robust wireless instruments deliver precise, continuous data and instant alerts in virtually all conditions.
Based in the UK and with operations in Europe, the Americas and Australia the company leads the way in designing, building and supporting a range of wireless remote condition monitoring technology that is used on railway infrastructure around the world.
Rail engineers choose these sensors and communications platforms for proven, precise monitoring of track, structures and earthworks because they are:
• Easy to install.
• Virtually maintenance-free.
• Deliver continuous data.
• Keep people informed without visiting site.
Wireless remote condition monitoring is an IoT (Internet of things) technology built around small, robust and affordable sensors that relay data to cloud-based data portals – usually via the cellular network. They can deliver near-continuous data over a remarkably long life (10 to 15 years) with minimal maintenance.
Wireless monitoring of track movement uses precise tilt sensors and other instruments to assess changes in twist, cant and settlement to warn engineers of short term, potentially dangerous problems. It also supports cost effective long term asset management by detecting trends in movement data that help to target maintenance resources where they are most needed. Complementary sensors monitor track temperature, strain, and displacement, while geotechnical sensors such as borehole in-place-inclinometers (IPIs) and piezometers provide insight on the relationship between track and deeper ground behaviour.
Monitoring of tunnels, bridges and other structures helps engineers to safeguard their integrity, for example when defects have been observed or where construction activity such as tunnelling or excavation is taking place nearby. Parameters that can be measured include structural movement (deformation, cracks, joints) load, ground pore water pressure and much more.
Monitoring earthworks and slopes
Wireless monitoring of earthworks such as cuttings and embankments provides early warning of landslides, rockfall and erosion and can automatically inform asset owners of potentially dangerous events if material encroaches on the track, or if track support is weakened, for example by flood damage. The responsive InfraGuard™ monitoring solution developed by Senceive and Network Rail engineers includes ground movement sensors linked to cameras so that alerts can be verified without visiting site, so that potentially dangerous events such as landslides can be verified and train drivers warned promptly.
It is also means that false alerts can be identified, reducing unnecessary disruption. InfraGuard systems are in place on more than 40 kilometres of track in southern England and are being deployed on railways and other infrastructure around the world.
Remote condition monitoring applications include:
• Structural health monitoring – tunnels, bridges, retaining walls.
• Geotechnical assets such as earthworks and slopes.
• Monitoring impact of construction activity.
