Description

technical field [0001] The invention relates to the technical field of marine water quality monitoring; in particular, it relates to a marine water quality remote measurement and control system based on multi-buoy sensing nodes. Background technique [0002] Ocean monitoring water quality buoys integrate sensor technology, data acquisition and processing technology, communication technology, satellite positioning technology and other high-tech technologies, but the current buoy-based ocean water quality monitoring technology still has the following shortcomings: [0003] 1. There is a bottleneck in the large-capacity, high-precision real-time data transmission technology of marine water quality parameters [0004] In the prior art, single buoys are often used in marine water quality monitoring to monitor relevant water quality parameters (temperature, salinity, dissolved oxygen, total nitrogen, total phosphorus, pH value, suspended matter, sulfide, chloride, ammonia, etc.) ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, single buoys are often used in marine water quality monitoring to monitor relevant water quality parameters (temperature, salinity, dissolved oxygen, total nitrogen, total phosphorus, pH value, suspended matter, sulfide, chloride, ammonia, etc.) , sulfate, heavy metals, oil spills, nuclear radiation, etc.) collection, processing and remote transmission operations; in view of the variability of marine hydrological parameters, this method cannot guarantee the stability of water quality parameter sampling in a specific period of time in this area, which requires a single The buoy repeatedly samples the water quality parameters in the area to suppress data collection errors caused by fluctuations in ocean hydrological parameters. The land remote measurement and control center could not make effective judgments in time, and missed the opportunity of governance

[0005] 2. The buoy power supply system for marine water quality monitoring is single, with poor power supply stability and battery life

However, with the improvement of long-term continuous observation requirements, the increase of equipped sensors and the expansion of monitoring functions, the existing energy management mode is far from meeting the actual needs, and even limits the expansion of buoy applications.
