Whether you are involved in railway construction or operation, you will need to measure and assess the attributes and performance of railway assets at some point in their lifecycle.
Wireless tiltmeters and other sensors are installed in minutes and typically last for 10 to 15 years. Most installations are done by non-specialists.
Use solutions that are tested, approved and proven at remote sites with no fixed (mains) power supply and that are sufficiently robust to stand up to most weather conditions, rail traffic and maintenance operations.
Remote monitoring means fewer site visits, reducing risk and cost.
Don’t wait for a train driver or member of the public to report debris on the track – detect ground or structural movement as it happens.
Identify long-term trends to keep infrastructure in use for longer, and target precious maintenance resources where they are most needed.
Detect track movement associated with traffic loading, weather events such as flooding, maintenance and construction activity and failure of supporting materials such as track foundations or embankemnts. All with wireless sensors that are built for the challenges of rail applications, are quick to install and provide precise measurement for many years after installation. Use the data to prioritise maintenance resources, to evaluate the effectiveness of interventions such as tamping or ballast cleaning , or to determine whether pre-identified movement has stabilized or is ongoing.
A wide range of track geometry defects and parameters can be measured, including cross-level, twist, slew, settlement and temperature. Sensors are usually fixed to track ties, but can easily be mounted on other track assets such as gantries, platforms and undertrack culverts. Wireless monitoring can provide an alternative or a supplementary approach to optical methods such as robotic total station or AMTS monitoring, mobile solutions such as a track recording vehicle or Amberg rail trolley. Wireless systems can be used alongside railway void meters and other railway track measurement systems.
Harness the smart remote monitoring power of Senceive intelligent monitoring technology – the World’s most widely used wireless remote monitoring solution for near real-time alerts of landslips, rockfalls and embankment failures. Remarkably simple and quick to install, it is precise, robust and responsive and can operate independently for more than a decade. The system not only sends alerts to remote stakeholders, but provides photo imagery so you can judge what steps to take without putting boots on the ground. It is the ideal slope stability monitoring tool where you need effective event detection.
Senceive intelligent monitoring technology has been proven again and again – preventing trains hitting track obstructions since 2019.
Engineers and asset managers face challenges relating to the age, over-use and deterioration of many bridges and structures and the difficulty in gaining access to inspect and maintain the structures.
Wireless monitoring can help protect bridge infrastructure by safeguarding vulnerable structures and extending asset life.
Wireless monitoring can also help protect the people who use bridges, and the people responsible for maintaining them:
Tunnel construction and maintenance professionals worldwide choose Senceive wireless condition monitoring technology to assess structural and ground behavior throughout the life of underground assets.
Precise movement sensors can be mounted to virtually any surface and can deliver data at set intervals (typically not more than every 30 minutes) on parameters including convergence, settlement and cracking. A wide range of third-party sensors can be integrated with Senceive wireless platforms to provide data on engineering parameters such as strain, torque and ground water pore pressure.
Innovative solutions are available to transfer data from underground sites using a combination of radio, Wi-Fi and cabled communications infrastructure.
Wireless monitoring has many advantages over more traditional methods:
Construction and maintenance activity can have potentially damaging structural effects on adjacent structures and property. Use wireless monitoring technology such as precise tilt sensors and crack sensors to safeguard infrastructure and protect your interests in the event of claims, by providing objective time-based data that can encompass modes of movement including deformation, rotation, convergence, settlement and cracking.
Sensors are remarkably small – little bigger than a tennis ball – which means they will not compromise track clearance and that most people will not even notice that a monitoring program is taking place. The sensors are built to withstand the challenges of rail and construction site conditions, and because there are no power or comms cables, there is minimal risk of the system being damaged.
