Introduction:

Daowan DW21 Buoy System employs a buoy platform integrated with multiple high-precision sensors and data acquisition units to enable Direct-reading or continuous monitoring of marine environment. Capable of measuring critical metrics including seawater temperature, salinity, depth, current and wave dynamics, the system delivers comprehensive data to support coastal management, climate studies and offshore operations.

System Components

1. Buoy Platform

Comprising a corrosion-resistant main frame, modular anchor system and integrated linkage mechanisms, the buoy serves as the structural foundation for all monitoring devices. Designed with a hydrodynamic profile, it ensures stability in harsh marine conditions. Optional recovery systems include submersible acoustic releases for flexible equipment retrieval.

2. Solar Power Supply System

Equipped with high-efficiency photovoltaic panels and deep-cycle batteries. Advanced power management ensures operation for long-term in low-light conditions.

3. Collision Avoidance & Safety Suite

Integrated with AIS transponders, solar-powered navigation lights and radar reflectors, this system broadcasts positioning data to nearby vessels via BeiDou/GPS positioning, mitigating collision risks.

4. Marine Environmental Monitoring package

Central Control Unit: Manages sensor networks and data acquisition.

Multi-Parameter Sensors: CTD (conductivity, temperature, depth), DO, pH, turbidity and nutrients.

Hydrodynamic Instruments: Acoustic Doppler current profilers (ADCPs) for current.

Subsea Cameras: High-definition imaging for ecological observation.

All components are interconnected via armored, power-communication hybrid cables for reliability.

5. Video Surveillance System

Above-Water Cameras: 360° pan-tilt-zoom (PTZ) units for buoy status checks.

Submersible Cameras: Rated for depths up to 200m, with 4K resolution.

Video streams are transmitted via 4G/5G networks.

6. Data Transmission System

Short-Range: LoRa or microwave for ≤15km line-of-sight.

Long-Range: Iridium/C-band satellite for global coverage.

7. Shore-Based Data Processing Center

Cloud-Based Analytics: AI-driven platforms for trend prediction and anomaly detection.

Hardware Infrastructure: Redundant servers, network switches and secure gateways.

User Interface: Customizable dashboards with GIS mapping and Direct-reading telemetry.
