Low-cost slope inclination observation solution for detecting landslides.
Low-cost slope inclination observation solution for detecting landslides.
Using the new wireless communication technology "LoRaWAN" and the latest sensor devices, monitoring of slopes and inclined lands, as well as recording measurement data.
Information from slope sensors installed on slopes and inclined surfaces is collected via the "LoRaWAN network," a new wireless communication technology, to a cloud data center. This not only reduces the burden of patrol duties by allowing the status of each sensor to be checked from a computer or smartphone, but it also enables immediate notification to managers in the event of a risk of slope collapse due to rainfall or earthquakes, allowing for quick decision-making from a safe location without the need to visit the site directly. Additionally, to capture changes in the slope comprehensively, it is necessary to install a large number of multi-point (scatter-type) sensors on the slope. By leveraging the procurement network that Greenhouse has developed over many years, we have achieved practical accuracy and the functionalities required by many operators while reducing total cost of ownership (TCO). Furthermore, not only can we monitor slope collapses, but we also allow for the downloading of measurement values, making it possible to use the data as materials or deliverables for routine inspections, such as ground inspection logs and weather observation records. *We offer a cloud service that allows you to monitor sensor information from a dedicated site.

basic information
■Features of the Solution - Information from multiple observation points is transmitted at high frequency, allowing for centralized management of individual sensor data from a distance. - By utilizing LPWA (Low Power Wide Area Network), communication costs have been significantly reduced. - The wireless devices are battery-operated, enabling installation in locations without restrictions, including areas where sunlight and power supply are difficult to secure. - The monitoring server is maintained and managed within a greenhouse, eliminating the need for server installation or maintenance on the customer’s side. - By reducing TCO, multi-point installation (scattering) has been made easier, facilitating the capture of slope deformations over a wider area.

Applications/Examples of results
Monitoring at over 520,000 locations nationwide where there is concern about the occurrence of landslides, as well as civil engineering construction sites undertaking disaster recovery work and slope protection work, is expected to be utilized in a wide range of scenarios that require tilt detection. Additionally, its structure is easy to install and maintain, and since it is battery-operated, it can be installed in locations without the need for a power supply, making it suitable for areas such as mountainous regions where securing power is difficult.
Detailed information
-
The data measured by the sensors is uploaded to the cloud via LoRaWAN, allowing for simultaneous multi-point observations using a web browser from an office set up near the site or from a distant headquarters. It is also possible to capture signs of landslides, debris flows, and slope failures over a wide area. In addition to monitoring slopes, the measurement data can be downloaded for use as materials and deliverables for routine inspections, such as records of daily inspections, geological inspection logs, and weather observation records.
