Landslides |Measurement of the dynamic state of landslides using inclinometers with a wireless function

Purpose of installation
Monitoring of landslide areas where slopes and roads have collapsed due to the effect of heavy rain from typhoons
Location
Kochi Prefecture

System Details

The changes to the slope over a planar area were determined by collecting and recording the measurement data of multiple inclinometers installed on the slope surface by wireless communication. Communication was carried out using mesh type special low-power radio which is strong against breakdown, so it was possible to reliably acquire the data from this mountainous valley area.
