Dam Monitoring

1.Dam Monitoring Monitoring Background

Dam Monitoring can measure surface displacement, internal displacement, groundwater level, rainfall, retaining wall pressure, concrete stress, seepage, temperature and humidity, etc.The safe flood control of reservoirs has always been a difficult and key point in my country's flood control and flood control.The safe flood control of small and medium-sized reservoirs has become a weak link in the current national flood control work.Most reservoirs lack necessary safety monitoring and other facilities, and the inspection methods are backward and there are great hidden dangers.Once local heavy rainstorms and floods occur, it is very easy to cause dam collapse.At the least, it will cause property losses, and at the worst, it will cause major casualties or devastating disasters.

As of the end of 2018, 98,822 reservoirs of various types have been built nationwide.However, most small and medium-sized reservoirs were built in the 1960s and 1970s and are trilateral projects.On the one hand, most reservoirs have low flood control standards, poor project quality, severe siltation, and shrinking effective reservoir capacity, and are in a state of operation with illness.On the other hand, many reservoirs have reached or exceeded their designed service life and are seriously aging, and the potential safety hazards of reservoir projects are prominent.

2.Overview of Dam Monitoring System

In order to achieve my country's goal of building digital water conservancy, our company took the lead in closely combining cloud computing with the Internet of Things and established an intelligent, automated and informative reservoir dam safety online monitoring system, which has functions such as remote data transmission and real-time online monitoring and early warning, which plays a crucial role in ensuring the safe operation of reservoir dams.

6.Dam Monitoring implements functions

1.The data can be displayed graphically, including water level flow relationship, water level process line, rainfall bar chart, osmotic pressure and seepage process line, time history curve chart, simulation chart, histogram, histogram, and other forms.

2.Real-time monitoring can be carried out in all weather conditions.

3.Once the monitoring data exceeds the preset value, timely warnings and notify relevant units to take corresponding measures immediately.
