Application and Significance of Buoy type water quality online monitoring system in Water Environment Management

The buoy-type online water quality monitoring system is a modern water body monitoring method. As an automated device for long-term and real-time monitoring of water quality, it is widely used in environmental monitoring of various water areas such as rivers, lakes, oceans, reservoirs, and aquaculture. Its core function is to continuously collect water quality-related data, providing a scientific basis for water environment management, pollution early warning, and ecological protection. It enables real-time observation of cloud data, facilitating staff to remotely access and view monitoring information.

The system mainly consists of three parts: the buoy body, the solar power supply system, and the monitoring system. The overall assembly process is simple and convenient. It only requires integrating sensors for various parameters onto the buoy and deploying it in the designated monitoring water area to operate normally, without complex on-site installation procedures, which greatly reduces the difficulty of deployment. Among them, the buoy body is made of corrosion-resistant and anti-aging polymer materials to ensure the stable floating of the device on the water surface and the safety of internal components; the solar power supply system adopts a mode of solar panels combined with storage batteries to provide power support for the long-term stable outdoor operation of the entire system, eliminating the need for frequent manual power supply; the monitoring system is the core functional module, including data collection, sensor monitoring, and other links.

The monitoring system of the system can be equipped with a variety of sensors, enabling real-time monitoring of multiple parameters of the corresponding water area. These parameters include not only the five conventional water quality parameters of pH, conductivity, turbidity, dissolved oxygen, and water temperature, but also special parameters such as ammonia nitrogen, nitrate nitrogen, total nitrogen, residual chlorine, COD (Chemical Oxygen Demand), suspended solids, ORP (Oxidation-Reduction Potential), chlorophyll, cyanobacteria, and various ions. Additionally, sensor types can be flexibly expanded to cover more monitoring indicators according to actual monitoring needs.

During operation, the sensors in the monitoring system directly contact the water body to collect real-time signals of the corresponding water quality parameters. These signals are converted into digital signals by the data collection module and then uploaded to the remote monitoring platform in real time through transmission methods such as 4G and 5G, thereby realizing real-time observation of cloud data. The system features continuous monitoring, unattended operation, and real-time data transmission, which can effectively avoid problems such as long time intervals and insufficient data representativeness existing in manual sampling and monitoring. Through the accumulation and analysis of long-term monitoring data, the changing laws of water quality in the water area can be accurately grasped. When abnormal fluctuations occur in water quality parameters, the monitoring platform can issue early warnings in a timely manner, helping relevant departments quickly take pollution prevention and control measures, which is of great significance for maintaining the health of the water environment.
