How the Wisen Wireless Mesh Network Works.

The key to this solution is a radio mesh network. Each node (or sensor) takes its own readings and relays data to other nodes, extending the range of the complete network. Nodes in a network will rearrange the routing of data to attain optimal transmission speed and reliability automatically. Information is then transferred from the Gateway to the internet which can be viewed directly through a browser or downloaded to a local computer via FTP for further processing. The nodes either have built in calibrated tilt sensors or are interface nodes for external sensors. All nodes have internal batteries and act as data harvesters collecting and transmitting readings into the radio mesh acting as both transmitter and repeater.

Vibrating Wire (VW) external sensors include: Joint/Crack, Strain Gauges, Piezometers, Extensometers, Load cells and Settlement gauges.

Tilt sensors are attached to sleepers to monitor movement. As the ground beneath the track moves the sleepers will tilt on either axis. Directional data is recorded and sent to the gaetway for monitoring and analysis.
