Description

technical field [0001] The invention relates to the field of marine environment monitoring, in particular to a seabed in-situ monitoring buoy system, a seabed in-situ monitoring system and a seabed in-situ monitoring method. Background technique [0002] With the development of the marine economy, marine pastures and marine environmental monitoring have put forward higher requirements for marine intelligent monitoring, and the existing seabed in-situ monitoring system can no longer meet the requirements. [0003] In terms of water quality monitoring, the existing technology mostly adopts water pump or winch to realize water quality monitoring, or adopts regular manual sampling or regular floating to collect data to monitor water quality, or uses some profile monitoring equipment to lower the measuring part into suspended water for measurement To monitor water quality, etc. However, the existing water quality monitoring technologies have their own shortcomings.

Problems solved by technology

However, the existing water quality monitoring technologies have their own shortcomings. Among them, the use of water pumps or winches for water quality monitoring loses the meaning of in-situ measurement and data distortion; the use of regular manual sampling or regular floating to collect data is not only costly , and the timeliness of the data cannot be guaranteed; some profile monitoring equipment is used to lower the measurement part into the suspended water for measurement, and the stability of the test data cannot be guaranteed because the monitoring equipment swings with the ocean current

That is to say, the existing water quality monitoring equipment cannot realize the function of in-situ long-term online monitoring on the seabed, especially the long-term real-time online monitoring function of in-situ high-definition video on the seabed

[0004] In addition, in terms of data transmission, the current seabed in-situ monitoring system mostly uses 3G, GPRS, Beidou, or satellite data communication. Among them, 3G signal coverage area is small, and many sea areas far from the coast cannot be covered; Beidou data communication rate is low. , and cannot transmit high-definition video; the video transmission cost of satellite data communication is high, and high-definition video transmission cannot be realized; this seriously restricts the application of in-situ high-definition video monitoring on the seabed, and cannot realize long-term real-time online monitoring of in-situ high-definition video on the seabed

[0005] Furthermore, the existing technology mostly adopts the method of laying submarine cables from the shore base to the floating platform for communication and power supply. Low speed, usually no more than 10M, and short transmission distance, usually no more than 3km

If the position of the floating platform is set at 3km to 20-50km offshore, the existing technology cannot realize it at all in terms of cost and transmission rate

If multi-point layout is adopted, the laying cost will be unbearable
