Problems solved by technology

[0003] The Henan Bureau has more than 10,000 river projects, and the annual inspection of dams consumes a lot of manpower and material resources. Even so, it is inevitable that there will be cases of missed inspections and reports, which will lead to small dangers turning into big ones, endangering the safety of flood control projects
Since 2003, many units have carried out automatic monitoring

Description

technical field [0001] The invention relates to a dam bank collapse detection device and system, in particular to a dam bank collapse detection wireless intelligent terminal device and an emergency pre-alarm system for dam bank collapse monitoring of rivers such as the Yellow River using the terminal device. Background technique [0002] In flood control and emergency rescue, embankment inspection is an extremely important task. The Yellow River has higher requirements for the monitoring of river engineering dam bank hazards because of its sediment-rich characteristics. In the final analysis, the problem of dam bank accidents is the problem of mulching. In other words, the root stone loss is the root cause of dangerous dam bank accidents, and reducing the loss of root stones can reduce the risk of accidents. In order to eliminate the danger caused by the loss of root stones in time, we must carry out accurate and rapid early warning of the loss of root stones and rescue them...
