Daowan buoy measurement system

The DW21 buoy measurement system is a professional level marine environment monitoring equipment designed for long-term, fixed-point acquisition of marine hydrological and meteorological parameters. The system integrates core modules such as high-precision temperature salinity depth gauge (CTD), ocean current meter, wave sensor, and meteorological station, which can monitor key parameters such as water temperature, salinity, depth, flow velocity and direction, wave height period, and wind speed and direction in real time. The data is transmitted back to the shore based monitoring center in real time through satellite communication or wireless transmission technology.

The DW21 system supports customized expansion and can be equipped with sensors such as dissolved oxygen, pH value, turbidity, etc. according to user needs to meet diverse monitoring requirements. Its low-power design ensures that the buoy measurement system can operate autonomously in remote waters for a long time, providing reliable data support for dynamic analysis of the marine environment.

The buoy marker includes the buoy main frame, anchoring system, and supporting linking equipment. It is the installation carrier for all equipment in the buoy monitoring system, providing a stable and reliable installation platform for the system. This system is equipped with both a positioning system and buoy lights to provide support for buoy and sensor recovery, as well as buoy collision avoidance.

The solar power supply system includes solar photovoltaic panels and batteries, which serve as the energy source for the buoy monitoring system and provide uninterrupted power supply.

As an underwater environmental perception system for ocean observation platforms, the Environmental Monitoring System integrates a main control unit, an integrated power communication submarine cable, a power supply system, underwater single unit cameras, CTD sensors, various other water quality sensors, single point current meters, acoustic Doppler cross-sectional velocity meters, and many other monitoring devices. It is the data acquisition and control core of the ocean observation platform.

The video surveillance system is divided into water-based video surveillance and underwater video surveillance. When deployed in the nearshore area, this system can be configured for buoys to monitor real-time video footage near the buoy, which is used to view buoy status and other information. The operator's network is used to transmit monitoring video signals.

The data transmission system is mainly used to transmit buoy data back to shore based servers or other user terminals. Depending on the offshore distance and on-site signal conditions, different data transmission methods can be flexibly equipped, such as 4G/5G, satellite communication, microwave, LoRa, etc.

The shore station data processing system includes software systems and supporting network equipment, server equipment, etc. It is a centralized monitoring and control center for human-computer interaction.

Float type:

Micro 0.6m buoy is suitable for rivers, lakes, and bays with low flow velocity and small wind waves, especially for lake water and nearshore net cage aquaculture.

Small 1.5m buoy is suitable for monitoring nearshore marine environments and can be equipped with sensors such as CTD to comprehensively monitor marine environmental data, providing comprehensive data support for scientific research monitoring, marine fisheries and aquaculture, marine environmental engineering, etc.

Medium sized 2.6m buoy has a larger size and stronger survivability in harsh marine environments such as deep seas, with stronger resistance to wind and waves.
