China's geological and geographical environment is complex, the climatic conditions are very different in time and space, and there are many types of geological disasters, wide distribution and great hazards, and it is one of the countries with the most serious geological disasters in the world. In order to realize the scientific, informational, standardized and visual management of geological disaster prevention and control, provide a scientific basis for disaster prevention and mitigation decision-making, and lay the foundation for the improvement of the quality, efficiency and management level of geological disaster prevention and control, the company makes full use of the current Internet of Things technology, intelligent sensing technology, cloud computing technology, embedded technology, communication and multimedia information technology, independent research and development equipment and application software system as the core, and provides a set of reliable, practical, Professional geological hazard monitoring and early warning system solutions.

        According to the provisions of the "Code for Monitoring Collapse, Landslide and Debris Flow" (DZ/T0221-2006), involving landslides, collapses, debris flows, land subsidence, etc.: deformation monitoring of landslide surface cracks and collapse cracks; monitoring of deep displacement of landslides and collapses; Oblique deformation monitoring of collapse body; debris flow displacement monitoring; rainfall monitoring; temperature monitoring; soil moisture monitoring; groundwater level monitoring; pore water pressure monitoring; earth pressure monitoring; geoacoustic monitoring; infrasound monitoring; surface crack monitoring; monitoring of land subsidence; video surveillance, etc.

Geological disaster monitoring and early warning cloud platform：

       Establish an informatization, database, and geological disaster monitoring data cloud platform; Carry out continuous, systematic and scientific monitoring of the status and influencing factors of geological disasters, realize a comprehensive grasp of the development status of geological disasters, and achieve the goal of "changes can be monitored, risks can be predicted, measures can be taken in advance, and dangers can be warned of dangers" through relevant models, correlation analysis, expert evaluation, and auxiliary decision-making. The scientific and perfect geological disaster monitoring and early warning solution realizes the scientific, informatization, standardization and visualization of geological disaster dynamic monitoring information, provides a scientific basis for disaster prevention and mitigation decision-making, and improves the ability of geological disaster early warning and forecasting and the rapid response ability of emergency response. The geological disaster monitoring and early warning platform uses intelligent sensing technology, GNSS technology, Internet of Things technology, cloud computing technology, and big data technology combined with professional geological disaster monitoring equipment to build a comprehensive solution for real-time monitoring, early warning and forecasting, information management, group measurement and group prevention, and auxiliary decision-making, which is widely used in real-time and online automatic monitoring of key geological hazards such as landslides, dangerous rock masses, collapses, ground subsidence, land subsidence and ground fissures.

      Data processing:
1) Overwrite multiple types of data; Numbers, pictures, documents, videos, drawings, etc
2) Centralized and unified storage of geological hazard status and structural safety data across regions and categories
3) Large-scale data storage space management
4) Efficient data indexing, fast and diverse data query
Diversified data display:
1) GIS graphical display, more intuitive and efficient
2) A variety of types of curve display patterns, flexible combination of chart display
3) Flexible display interval and combination display of a variety of monitoring data

Early warning system for timely response:
1) Fine-grained, quantitative early warning threshold setting, convenient threshold adjustment
2) Real-time display of early warning on the monitoring platform
3) Synchronous remote alarm, send the alarm information to the mobile terminal of the manager's mobile phone

On the basis of professional sensor benchmarking, the original sensor data is obtained, and limited data filtering is adopted to truly present the geological disaster field data. In the process of collection, transmission and storage, a restraint mechanism is adopted to ensure the integrity of the data. The scientific processing of data anomalies such as data loss, data drift, long-term interference, hopping points, weak noise, and dry noise on the timeline ensures the continuity of data. Diversity and relevance, efficiency and applicability, value and validation, provide value data for the monitoring of disaster conditions. Periodic real-time professional curve presentation of time-domain and frequency-domain data, and correlation presentation of single and multi-indicator combinations to achieve data-rich visual presentation. Trend analysis, correlation analysis, regression analysis and deep coupling with geological hazard models provide value analysis for disaster laws. Combined with geological hazard models and expert opinions, the early warning of geological disasters is scientifically realized.
