A novel wireless underground transceiver for landslide internal parameter monitoring based on magnetic induction

This article introduces a magnetic induction communication transceiver MI-S125-III, which can be buried in a landslide body and can be used to transmit the internal characteristic parameters of landslide mass (such as inclination angle). The device is based on the Manchester code, and the working frequency is 125 kHz. Its data transmission distance can reach 5.28 m in the soil. We built a physical landslide model, in which three MI-S125-III nodes with a tilting sensor were embedded, and the angle monitoring curve was obtained by human triggering. The angle monitoring curve can reflect the sliding process, indicating that MI-S125-III can be used for landslide monitoring and early warning in the future.

Automated summary

This article presents a magnetic induction communication transceiver MI-S125-III for transmitting internal characteristic parameters of landslide mass. Experimental results from a physical model show that the device can monitor the inclination angle of landslides and track the sliding process.
