IoT solution dedicated to early-warning and monitoring of displacements.
In order to face the challenging problem of realizing efficient and cost-effective solutions dedicated to monitoring and early-warning of areas and critical infrastructures subject to hydro-geological instability, YETITMOVES has developed DISPLAYCE.
DISPLAYCE is an innovative and cost-effective Internet of Things (IoT) solution based on low-cost single-frequency GNSS sensors capable to compete with expensive professional instruments in term of reliability and efficiency.
FIELDS OF APPLICATION
Monitoring and early-warning of areas subject to hydro-geological instability (landslides, bradyseism, sinking, subsidence, etc.)
Monitoring and early-warning of critical infrastructures and sites such as pipelines, geothermal energy plants, dams, towers, high voltage pylons, chimneys, bridges, viaducts, railroads, motorways, ports, natural gas storage sites, schools, historical buildings, archaeological sites, building sites, river basins, quarries, etc.
Respect to GNSS commonly used for geophysical and structural monitoring applications, DISPLAYCE presents a series of innovative technological features:
DISPLAYCE sensors are light, small and completely autonomous from the point of view of data transmission and power supply (the battery is dimensioned to guarantee an autonomy of at least 10 days in the absence of an external power supply). These features make them easy and quick to install on the ground or on buildings or infrastructures.
DISPLAYCE monitoring solution is complete: it includes everything needed for monitoring: GNSS sensors, real-time data transmission system, measurement acquisition and calculation software, client applications for displaying the measurement time series and monitoring network status, e-mail and/or SMS alert system in case of malfunctions or anomalous movements detected.
DISPLAYCE receivers are cost-effective if compared to instrumentation traditionally used for these applications. They have comparable performances in terms of displacements repeatability. Even with a low budget it is possible to implement widespread monitoring networks on the area of interest.
DISPLAYCE is compliant with the European standards (CE marking)
DISPLAYCE nodes are composed of lightweight, compact, low-power-consumption, single-frequency GNSS stations, power supply modules based on photo-voltaic panels and 868 MHz wireless interface for data transmission.
The gateway node transmits GNSS data in real-time to a processing server, where surface displacements are computed with millimeter level repeatability using state of the art software tools developed by YETITMOVES.
The server publishes computed data through REST web services. For this reason data can be easily integrated in already existing monitoring and early-warning dashboards.
A client desktop application (dashboard) shows the computed three-dimensional displacements, the status of monitoring network (batteries and photo-voltaic panels voltages, GNSS data quality, efficiency of wireless transmission, etc.), the system configuration parameters.
DISPLAYCE is able to automatically send periodic reports and alert messages through e-mails or SMS.
