Description

Technical Field

[0001] The utility model relates to the field of dam safety monitoring, in particular to a dam safety monitoring system. Background Art

[0002] As we all know, dams refer to weirs that intercept rivers and water, as well as corresponding water-blocking embankments for reservoirs and rivers. Their function is to raise the water level of rivers and form upstream regulating reservoirs. The safety of dams is extremely important, so the monitoring of dam safety should be strengthened. After the dam is built and during its use, while strengthening the monitoring of dam safety, full consideration should also be given to the impact on the surrounding environment. That is, dam safety monitoring is an effective means to monitor project safety, understand the operating status and safety status of the dam, improve the design level, and improve construction methods. Therefore, the safety of dam operation is extremely important, and long-term safety monitoring of dams is required.

With the continuous development of the use of dams and related technologies, the traditional single-function measurement and control devices and layout methods can no longer provide comprehensive monitoring of dams. Analysis shows that most reservoirs lack the necessary water and rainfall monitoring and dam internal safety monitoring facilities, and there are great monitoring risks. Utility Model Content
