As an important infrastructure of the country, the safe operation of reservoirs and dams is directly related to the safety of people's lives and property and social stability. However, due to the influence of various factors, reservoir dams may have safety hazards such as cracks, landslides, subsidence, etc. In order to detect and solve these problems in a timely manner, the reservoir dam monitoring and early warning system came into being. 
Introduction to GNSS displacement monitoring stations.
GNSS displacement monitoring station is a high-precision displacement monitoring equipment based on global positioning system and Beidou satellite navigation system. By receiving satellite signals, it can monitor the displacement, settlement and other changes of the reservoir dam in real time, and transmit the data to the monitoring center for analysis and processing. GNSS displacement monitoring station has the advantages of high precision, all-weather, automation, etc., and can be widely used in the monitoring and early warning of various reservoirs, dams, bridges, tunnels and other projects.
Reservoir dam monitoring and early warning solutions
The reservoir dam monitoring and early warning solution based on GNSS displacement monitoring station is mainly composed of the following parts:
In the reservoir dam area that needs to be monitored, a certain number of GNSS displacement monitoring stations should be reasonably laid out according to the scale of the project, geological conditions and other factors. The location of the monitoring station should be able to fully cover the dam area and ensure the accuracy and reliability of the monitoring data.
Early warning system According to the data processing results, combined with the safety threshold of the reservoir dam, the early warning information is automatically generated. The early warning information can be notified to the relevant personnel in a timely manner through SMS, ** email and other methods, so that corresponding emergency measures can be taken.
Emergency response and feedback After receiving the early warning information, relevant personnel should immediately take emergency response measures, including organizing personnel evacuation, activating rescue plans, etc. At the same time, the inspection and monitoring of reservoirs and dams should be strengthened to grasp the changing trend of dam safety in a timely manner. In the process of disposal, the progress and results of disposal should be fed back to the monitoring center in a timely manner, so as to continuously improve and optimize the early warning system.
