The water level and rainfall monitoring systems for rivers and reservoirs provide important support for regional flood prevention and disaster reduction work, and have shown good demonstration value in practical applications. In this context, the effective implementation of flood control and flood fighting work has attracted much attention, and timely grasp of the water level changes in rivers and reservoirs during the flood season is of great significance for improving the efficiency of flood control and flood fighting work.
A large number of rivers and reservoirs are located in areas far from cities. Relying solely on traditional manual inspections to obtain river water level data will consume a lot of human and material resources. The Water Level Monitoring System can provide users with professional and comprehensive water level monitoring, control and management services. The system monitors real-time changes in water level through water level sensors and transmits relevant data to the administrator's WEB terminal or mobile APP. Compared with traditional water level stations, it has the advantages of quick data viewing, automatic over-limit alarm, automatic recording and uploading, etc. Administrators can keep abreast of the situation on the computer or mobile phone without going to the water level station.
In terms of system composition, the Water Level Monitoring System uses radar or pressure-type water level sensors to sense water level changes, integrating solar power supply, video monitoring and wireless transmission equipment. It has functions such as water level collection, over-limit alarm, automatic recording and uploading, low battery alarm, and site file viewing. The real-time monitored water level data will be transmitted to an independent cloud server through GPRS and 4G signals, and then the cloud server platform will send the data to the administrator's computer WEB terminal or mobile APP.
The liquid level sensor has many characteristics: high precision, good stability, and strong anti-interference ability; adopts multi-level lightning protection design, with good anti-lightning effect; good long-term stability of full scale and zero position; solid structure, no moving parts, high reliability, long service life, and equipped with reverse maintenance and current limiting maintenance circuits, so the transmitter will not be damaged if the positive and negative poles are connected reversely during installation; convenient installation, simple structure, economical and durable; suitable for multi-point pressure parameter networking collection, the bus supports multiple devices, with corresponding output and communication functions, and high output current resolution.
System functions include: remote setting function, the computer of the monitoring station can remotely set the warning water level value of the subordinate monitoring points; automatic transmission alarm function, when the water level exceeds the early warning water level, the measuring and reporting device will automatically report the water level information to the computer of the monitoring station and send it to the administrator's mobile phone at the same time; data file function, all data information of the system will be automatically stored in the large database of the computer, facilitating data retrieval and data analysis.
The Water Level Monitoring System is suitable for water level measurement and early warning in reservoirs, rivers, lakes, dams and other areas, and can also be widely used in agriculture, forestry, environmental protection, shipping and other industries. It is an efficient device for monitoring water level changes, which can provide accurate real-time and historical water level data. Through the integrated application of multiple functions, it realizes the information-based management of rivers, greatly reduces the risk of excessive water levels and river breaches, and plays an important role in ensuring the safety of people's lives and property.
