WIRELESS MONITORING FOR TUNNELS
Wireless monitoring plays a valuable role in the construction and maintenance of various tunnel elements and underground structures:
Refurbishment and structural modification, for example for strengthening, track lowering and electrification Monitoring movement of third-party buildings and assets
Shafts and diaphragm walls
Temporary works New construction
As with any of our wireless monitoring solutions, a typical tunnel monitoring system will comprise three key elements : sensors, a cellular communications gateway and an online data portal. For dense sensor networks and highly responsive reporting, choose our FlatMesh™
intelligent mesh platform. Where sensors are widely dispersed and where you need to transmit data through physical obstructions (including soil and rock) our long-range GeoWAN™ platform may be more suitable.
In order to relay data from the sensor positions deep underground to the Gateway that is typically located just outside the portal, repeater nodes may be used. Alternatively, Wi-Fi or ethernet connections can be used where available.
