- Abstract:
- In this paper, we present the performance of a landslide transducer based on magnetic strain gauges and the interpretation of experimental results. Analysis of landslide data indicates that the land displacements measured with our transducer are correlated to the movements measured at the ground surface. Evaluating the landslide data, we have established a relationship between the system readings and the landslide movement. Measurements regarding landslide displacement and orientation were done using strain gauges based on amorphous magnetic microwires (MAW). In order to evaluate a larger area, our system uses a grid of measurement points containing multiple measurement nodes. Each measurement node acquires displacement and orientation information reporting the data through RS485 to the central unit coordinator. Measurement information from central unit coordinators across the grid is transmitted wirelessly to a server for storage and alerting actions.
