Landslide
1. Monitoring Background
In recent years, with the continuous progress of scientific and technological means and the continuous improvement of information technology, disciplines cross each other and penetrate deeper and deeper. Slope prevention and control work, especially slope monitoring, has developed from traditional and simple manual measurement of steel ruler, caliper and other tools to single geodetic measurement and leveling measurement to real-time monitoring of the hidden danger point, in order to find out the change and deformation signs of the slope in time, grasp the occurrence and development trend of the slope, adopt wired and wireless transmission technology, carry out long-distance automatic collection, transmission and analysis service platform data processing of the information obtained from instrument monitoring, and release early warning information in time, so as to take effective prevention and control measures before and after the disaster, Minimize or avoid the loss of people's life and property caused by slope.
2. System Overview
The slope monitoring sensors (rainfall, surface displacement, deep displacement, retaining wall inclination, retaining wall crack, retaining wall pressure, image, groundwater, sudden moisture content, anchor cable stress, environmental temperature and humidity, wind speed and direction, etc.), wireless data transmission system, video monitoring and joint adjustment equipment shall be laid at the hidden slope. The information obtained by the application of sensor monitoring is automatically collected by remote control and transmitted data service platform for data processing, and early warning information is released in a timely manner. And provide technical support work after early warning. The main purpose is the following:
Build a slope early warning platform with the functions of disaster overview, professional monitoring, early warning analysis, emergency inspection, comprehensive management, etc., to realize the scientific, information-based, standardized and visualized management of slope hidden danger prevention and control, and to improve the quality, efficiency and management level of slope prevention and control work as a whole;
Through professional monitoring equipment, the construction of automatic monitoring system covering the hidden danger of slope, improve the intelligent level of slope automatic monitoring and early warning, and improve the ability of monitoring and early warning.
Through the construction of slope professional automatic monitoring system, the transformation from passive rescue and disaster relief to active disaster prevention, disaster reduction and disaster avoidance can be realized, so as to ensure the safety of people's lives and property.

System function
Data big screen
Customized data large screen to meet the different needs of customers, showing different data information.
real-time monitoring
24 hours uninterrupted real-time monitoring.
Data alarm
According to the different range of monitoring and control indicators, the early warning is divided into three levels for monitoring process management, and the monitoring data is compared with the three-level early warning value to determine the monitoring and early warning level of the site. And through the platform, SMS and email to notify the relevant responsible person.
Data analysis
Including comparative analysis, correlation analysis, time domain analysis, frequency domain analysis and other analysis methods.
Patrol inspection and maintenance
Make patrol inspection plan, record, repair and maintain the diseased parts.
Report generation
Users can set different report generation rules based on customized report templates and general report templates, and automatically generate their own monitoring data reports.
Security Assessment
Combined with the inspection record data, monitoring data and detection data, the weight of different parts of the structure is scored, and finally the overall safety score of the structure is obtained.
