Suzhou Changshu Smart Fishery Project -3

Water Quality Monitoring Buoy Station in the Smart Fishery Project of Changshu, Suzhou

The water quality monitoring buoy station in the Smart Fishery Project of Changshu, Suzhou, is an essential facility for achieving real‑time, continuous water quality monitoring in aquaculture waters. By integrating multiple sensors and advanced IoT technologies, it provides a scientific basis for fishery production and ensures the quality and safety of aquatic products.

I. Functional Features

Multi‑parameter Monitoring: Capable of simultaneously monitoring multiple water quality parameters, including temperature, dissolved oxygen, pH, electrical conductivity, turbidity, ammonia nitrogen, nitrite, and others.

Data Transmission and Processing: Utilizes wireless communication technologies (e.g., GPRS, 4G, or LoRa) to transmit collected data in real time to a cloud platform or data center for remote access and analysis.

Intelligent Early Warning System: Based on preset thresholds, automatically triggers an alarm mechanism when any monitored water quality parameter exceeds the safe range, and notifies relevant personnel via SMS, email, or other means to take action.

Self‑Powered System: Equipped with solar panels and batteries to ensure stable operation under various environmental conditions.

II. Main Components

Buoy Body: Made of corrosion‑resistant materials, offering good buoyancy and stability to adapt to different water conditions.

Sensor Module: Equipped with multiple high‑precision sensors for real‑time monitoring of changes in water quality parameters.

Data Acquisition and Control Unit: Responsible for collecting data from each sensor and performing preliminary data processing tasks.

Communication Module: Supports wireless data transmission to ensure timely delivery of information.

Power Management System: Includes solar charging devices and energy storage units to ensure long‑term stable operation.

III. Application Scenarios

Marine Aquaculture Areas: Suitable for water quality monitoring in coastal aquaculture areas for high‑value aquatic products such as shellfish and finfish.

Freshwater Lakes and Rivers: Can be used for ecological and environmental monitoring in inland lakes, reservoirs, and major river sections.

Ecological Reserves: Helps reserve managers understand water health conditions and formulate appropriate protection strategies.

IV. Advantages

Round‑the‑Clock Online Monitoring: Unaffected by weather conditions, providing 24/7 uninterrupted water quality information.

Efficient Management and Decision Support: Based on big data analysis results, guides optimization and adjustments of fishery production to improve yield and quality.

Reduced Environmental Pollution Risk: Enables rapid response to water quality changes, taking timely measures to prevent pollution spread.

By deploying water quality monitoring buoy stations, the Smart Fishery Project can not only effectively improve farming efficiency and product quality but also promote sustainable fishery development and protect marine and freshwater ecological environments. This is of great significance for advancing modern fisheries toward intelligent and green development.
