The river water level monitoring system program is an important means for real-time monitoring of changes in river regimes, scientifically warning flood disasters, improving flood prevention command capacity, and reducing rain and flood losses. Monitor the water level changes in the river, forecast the arrival of floods, and tell people in advance to do a good job of protecting the property in the home. For the prediction of natural disasters In the Eastern Han Dynasty of China, there were great scientists Zhang Heng invented the earliest seismograph in the world to monitor the occurrence of earthquakes. Nowadays, with the rapid development of science and technology, the invention of our innovative technical talents is changing with each passing day. At the same time, the instruments used to monitor the environment we depend on have also undergone major changes. For example, instruments used to monitor earthquakes have become more accurate and high-tech integrated. Now, Gongye.com Xiaobian talks about water level monitoring in water conservancy projects. Water level monitoring is an important link to protect our human survival. We first briefly understand the importance of water level monitoring through a set of data. The flood control characteristics of some major river control stations in Hubei in a certain year: River Name site name Flood control characteristics of rivers Warning level (m) Guaranteed water level (m) Yangtze Yichang 53 55.73 Zhicheng 49 51.75 Shashi 43 45 Shishou 38.5 40.38 Luoshan 32 34.01 Hankou 27 29.73 Han River Yicheng 57.5 59.3 Huangzhuang 48 50.62 Yuekou 37.9 40.62 Hanchuan 29 31.69 Through the above data, we can understand the height of the flood warning water level of the whole river. Once these heights are reached, it means that the current water level is highly dangerous, it will cause flood disasters, and we need to be vigilant to monitor the changes of the whole river in time. At the same time, when the monitoring of the river's water level rises and changes rapidly, flood disasters may occur. At this time, it is necessary to evacuate the people in time to make protection measures. When monitoring the rapid decline in the water level of the river changes, it is likely to form a drought, the need for early warning of water storage, crop drainage and so on. Therefore, the flood control characteristics of rivers and lakes is an important basis for flood prevention and drought prevention organization and flood rescue and rescue. Therefore, the monitoring of the water level is indispensable. Nowadays, with the development of science and technology, people's lives are more protected, and monitoring of rivers, dams and other equipment is becoming more and more advanced. For example, the device in the figure below is a new discovery of this article. This device uses an ultrasonic sensor that converts ultrasonic signals into electrical signals. It is powered by a solar panel to measure the height of the river's water level, and collects height data in real time. , Send data to the centralized processing system through radio communication. This equipment makes full use of solar energy, which is both environmentally friendly and energy-efficient. It also makes use of radio transmission data, which is cost-effective and efficient. In general, the development of science and technology has improved people's lives. Finally, we recommend a low-power, small-footprint ultrasonic sensor suitable for detecting changes in the water level of the river, the MB7066. It is a small but robust weather-resistant ultrasonic sensor. Meets IP67 protection and safety grade, can protect dust from inhalation and can be soaked briefly. With high output sound power and continuously variable gain, it can be automatically calibrated in real time and has a good noise suppression algorithm, which can effectively achieve noiseless distance readings. Even in the presence of many acoustic or electronic noise sources, stable and reliable distance readings can be obtained. With a measurable distance of up to 10 meters, it is well applied in long-distance detection and liquid level detection. Multi Circuit Iot Energy Meter
