Landslide early warning device based on anchor magnetic monitoring - summary node & terminal node base plate

  The functions of the device include magnetic monitoring of anchor rods, data collection and transfer, and early warning information display. The device is divided into terminal nodes and summary nodes, and the nodes are controlled by STM32. The terminal node uses the Bluetooth Mesh network to collect geomagnetic data in the anchoring area and uses Kalman filtering to reduce noise interference; the summary node collects standard geomagnetic data, and by comparing and analyzing the geomagnetic data of the terminal node, the relative displacement index and inclination of the mountain are obtained, and soil moisture is measured at the same time and rainfall index to assist in early warning level determination, and then use the NB-IOT module to transmit it to the Tuya Cloud platform; the cloud will use the obtained data to output the early warning level signal through the landslide early warning model based on the fuzzy system, and the user can selectively issue it based on the signal and specific conditions.
