The invention has the advantages of safe and convenient operation, low power consumption, strong anti-interference, good expandability, accurate and safe real-time monitoring data and the like.

Description

technical field [0001] The invention relates to a marine monitoring system, in particular to a real-time monitoring system for anoxic phenomenon at the bottom of the offshore ocean, which is mainly used for real-time and accurate monitoring of water quality parameter data closely related to the phenomenon of hypoxia at the bottom of the offshore ocean. Background technique [0002] The anoxic phenomenon of water bodies with a dissolved oxygen content of less than or equal to 2 mg / L in sea bottom seawater has become one of the major ecological and environmental problems in the world. Offshore waters, especially estuary areas, on the one hand, the input of a large amount of nutrients and organic matter is likely to cause red tides, and on the other hand, the dissolved oxygen in the bottom seawater is rapidly consumed, and its concentration gradually decreases to form a "hypoxic zone". "Oxygen zone", also known as "dead zone", not only fish, shrimp and shellfish cannot survive ...

AI Technical Summary

Problems solved by technology

The monitoring system sends the sea bottom water level data to the shore station in real time through wireless transmission and signal relay. There is still a certain distance in terms of anti-interference and scalability, and it is difficult to apply to the monitoring of marine hypoxia

CN100564152C "A Self-sustaining Marine Environment Monitoring System" discloses a marine environment monitoring system comprising a sea surface buoy, a measuring platform and an anchoring system, which can measure water body parameters. However, the monitoring data of the monitoring system adopts self-contained storage, Need to recover the monitoring system to read again, it does not involve data transmission technology, so real-time monitoring cannot be carried out
