Monitoring and early warning system for landslides: a precise carrier for geological disaster prevention and control
【 BK-BP1 】 Shandong Boke Instrument is customer-centric, service-oriented, and driven by innovation.
The landslide monitoring and early warning system integrates multiple technologies to achieve dynamic monitoring of the entire stage of landslide incubation, development, and occurrence. The system consists of a front-end monitoring network, a data transmission network, and an early warning platform. The front-end equipment includes GNSS displacement stations, soil moisture sensors, inclination sensors, etc. Key monitoring points are set up at the rear edge cracks, middle shear outlets, and front edge foot of the landslide body.
In the monitoring of landslides in Ailao Mountain, Yunnan Province, the system analyzed GNSS displacement data and soil moisture content data and found that the landslide body entered an accelerated deformation stage 36 hours after rainfall. A warning was issued 48 hours in advance and more than 200 villagers were successfully relocated. The system adopts machine learning algorithms to optimize the warning model, and improves the accuracy of warning by training historical landslide data. Currently, the mainstream system's warning accuracy can reach over 85%. For remote mountainous areas, the system adopts solar power supply and Beidou communication to reduce operation and maintenance costs. At the same time, it has equipment fault self diagnosis function, which automatically sends maintenance reminders when faults occur, ensuring long-term stable operation of the system.
