The program of the river water level monitoring system is an important means to grasp the changes of river water conditions in real time, to scientifically warn flood disasters, improve the ability of flood control command, and reduce rain and flood disaster losses. It is important to monitor changes in the water level of the river, predict the arrival of floods, and tell people in advance to protect their homes.
For the prediction of natural disasters in the Eastern Han Dynasty, the great scientist Zhang Heng invented the world's earliest seismograph to monitor the occurrence of earthquakes. Nowadays, science and technology are developing rapidly, and the inventions of our innovative technical talents are also changing with each passing day. At the same time, the equipment used to monitor the environment on which we live has also undergone great changes. For example, the instruments used to monitor earthquakes are becoming more and more accurate and integrated with high technology. Now, let's talk about water level monitoring in water conservancy projects.
Through data investigation, it can be understood that if the flood control water level of the entire river reaches a certain height, it represents a danger and flood disasters will occur. It is necessary to stay vigilant and monitor the changes of the entire river in time. At the same time, when the water level of the monitoring river rises and changes rapidly, flood disasters are likely to occur. At this time, people must be evacuated in time and protective measures must be taken. When the water level of the monitoring river changes rapidly, it is likely to be a drought, and early warning of water storage and crop drainage are needed. Therefore, the characteristic water level of rivers and lakes for flood prevention is an important basis for the organization and command of flood prevention and drought prevention and flood fighting and emergency rescue. Therefore, water level monitoring is indispensable.
Nowadays, with the development of science and technology, people's lives are more protected, and the equipment for monitoring rivers and dams is becoming more and more advanced. This equipment uses an ultrasonic sensor for detecting water level that converts ultrasonic signals into electrical signals. And it leverages solar power panels to supply power to detect the height of the river water level, collect the height data of the water level in real time, and send the data to centralized processing system via radio communication. This equipment makes full use of solar energy, which is environmentally friendly and energy-saving. It also uses radio to transmit data, which is cost-effective and efficient. Generally speaking, the development of technology has improved people's lives.
