Dam Monitoring

1. Dam Monitoring monitoring background

Dam Monitoring Real-time monitoring of dam displacement, seepage, seepage pressure, upstream and downstream water levels, rainfall, temperature and other operating conditions.The safe flood control of reservoirs has always been the difficulty and focus of my country's flood prevention and 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 have great hidden dangers..Once local heavy rains and floods occur, it is very easy to cause a dam breach, which may cause property losses at least, or cause heavy casualties or devastating disasters at worst.

As of the end of 2018, 98,822 reservoirs of various types have been built across the country.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 engineering quality, serious siltation, and limited effective storage capacity.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 outstanding.

2.Overview of Dam Monitoring system

In order to achieve the goal of building digital water conservancy in my country, our company has taken the lead in closely integrating cloud computing with the Internet of Things to establish an intelligent, automated, and information-based online reservoir and dam safety monitoring system with remote data transmission, real-time online monitoring and early warning, etc.Function plays a vital role in ensuring the safe operation of reservoir dams.

6.Dam Monitoring implementation function

1.Data can be displayed graphically, including water level and flow relationships, water level process lines, rainfall histograms, seepage pressure and seepage process lines, time history curves, simulation diagrams, histograms, histograms, etc.

2.Can carry out all-weather real-time monitoring under various climate conditions.

3.Once the monitoring data exceeds the preset value, a timely warning can be issued and relevant units can be notified to take corresponding measures immediately.
