TECHNICAL FIELD

[0001] The present application relates to the field of marine environment multi-parameter monitoring, and particularly relates to a stable marine environment monitoring device based on multi-parameter measurement. BACKGROUND

[0002] Marine environment multi-parameter monitoring is a process of carrying out synchronous observation and analysis on multiple environmental parameters in the ocean by means of sensors, remote sensing technology and data acquisition systems, etc. The monitoring parameters are various, covering seawater temperature, salinity, flow rate, wave, etc. in the physical layer, dissolved oxygen, pH value, nutrient salt, heavy metal content, etc. in the chemical layer, and chlorophyll concentration, plankton distribution, etc. in the biological layer. The monitoring work is of great significance. On the one hand, it can provide key data support for marine ecological research, helping researchers to deeply understand the structure and function of the marine ecological system; on the other hand, it can serve the marine environment management and provide basis for decision-making of marine pollution prevention and control, marine resource development, etc. For example, through real-time monitoring of red tide related parameters, red tide disasters can be timely warned; monitoring of the degree of ocean acidification helps to assess the impact of climate change on the ocean. At present, marine environment multi-parameter monitoring is developing towards automation, intelligence and networking, and various monitoring equipment such as buoys, subsurface buoys and underwater robots are widely used to realize long-term, continuous and three-dimensional monitoring of the marine environment, providing protection for marine scientific research and marine environment protection.
