Railways in many parts of the world are built on embankments or adjacent to steep slopes. Failures can manifest in gradual settlement and disruption, or sudden landslips, and can pose a significant threat to human life. Historic management practice has been based on manual inspection and attended survey. More recent technological development has brought automated survey instruments, remote sensing and better data management, e.g. improved weather forecasting. All have limitations, however, such as limited spatial and temporal sampling and the need for frequent site visits and associated costs and risks. Remote condition monitoring specialist Senceive has pioneered the use of IoT technology over the last decade to provide a robust and proven wireless intelligent monitoring solution (IMS) to detect and respond to ground movement and provide early warning to geographically dispersed stakeholders. The core element of the system is a network of long-life movement sensors connected to each other and the internet via a wireless radio platform. The Senceive IMS incorporates many of the properties common to other IoT technologies: it is cost-effective; small; easy to install and needs little or no maintenance over an ultra-long (10-15 year) life. It does not need mains power and has self-healing properties in the event of damage to individual components. It can integrate triaxial movement sensors with a wide range of other sensors including automated cameras as well as geotechnical and structural logging instruments.
