Application of RTU in hydrological monitoring of small and medium-sized rivers

my country has heavy rainfall in summer, and flood control work in small and medium-sized rivers often becomes the focus of preventing floods during the rainy season. Therefore, in today’s highly developed Internet of Things technology, using Internet of Things technology to monitor small and medium-sized rivers and establishing a hydrological monitoring system for small and medium-sized rivers can effectively monitor water and rain conditions in real time, and can effectively predict hydrological changes and prevent floods in advance. Know your work well and take the initiative.

The Zongheng Intelligent Control Hydrological Monitoring System for small and medium-sized rivers uploads the detected information such as humidity, wind speed, rainfall, water quality, flow speed, water level, video images and other information to the online monitoring center through various detectors. Through the large screen spliced in the monitoring center, online monitoring data, images, videos and other information are realized, allowing monitoring personnel to remotely monitor the scene in real time, accurately judge the status of the river, and achieve accurate prevention and control of flood disasters.

The Zongheng Intelligent Control Hydrological Monitoring System for small and medium-sized rivers is suitable for various hydrological departments to conduct real-time monitoring of hydrological parameters such as rivers, rivers, lakes, reservoirs, channels and groundwater. Monitoring content includes: water level, flow, flow rate, rainfall (snow), evaporation, sediment, ice, moisture, water quality, etc. The system uses wireless communication to transmit monitoring data in real time and can transmit data to multiple centers at the same time, reducing the workload of manual field surveys and greatly improving the work efficiency of the hydrology department.

System composition

Zongheng Intelligent Control’s hydrological monitoring system for small and medium-sized rivers is divided into three parts: front-end collection end, data transmission end, and monitoring center end.

Front-end collection end: The front-end collection equipment includes temperature and hygrometer, wind direction anemometer, rain gauge, flow meter, water level gauge, camera and other equipment, which is responsible for detecting temperature, humidity, wind speed, wind direction, rainfall, water quality, water velocity, water volume, water level, Digital information such as video images.

Data transmission end: Data transmission uses Zongheng Intelligent Control RTU , relying on the wireless networks with high coverage of major operators to transmit the collected data through 4G/2G networks to achieve the purpose of remote monitoring.

Monitoring center: The monitoring center is mainly composed of a data server, an application server and a large monitoring screen. It implements functions such as data storage, calculation, analysis and monitoring, processes the data returned by the front end in a timely manner, and monitors rainfall information in real time. According to the water level and Image data can provide timely flood disaster warning to downstream areas.
