Technical solution for online monitoring system of aquaculture water quality

1 Project Background

At present, the water quality monitoring of domestic aquaculture is still basically in the manual sampling and chemical analysis stage, which is time-consuming, labor-intensive, low-precision, and requires professional personnel to operate. The automatic water quality monitoring system is simple to operate, with fast and accurate numerical output, and can achieve continuous or timely monitoring of the entire aquaculture process. It is of great significance to prevent extreme water quality physical indicators caused by extreme climate and the disease mechanism of various water environmental factors. It can guide our aquaculture industry to avoid risks and bring profits.

With the development of aquaculture, the entire aquaculture industry will undergo a complete change in business concepts in the near future, and will gradually choose advanced water quality monitoring systems to serve the aquaculture process. Use analyzers to achieve data collection. The analyzer's sensor measures the original data and obtains the measured parameter value through signal analysis. One or more analyzer sensors can be placed in the aquaculture pond, and the analyzers are connected by RS485 communication, so that multiple parameters of the water environment in the aquaculture pond can be continuously collected.

The main functions of the online water quality monitoring system of the breeding center include the analyzer as the lower computer, data acquisition and transmission equipment and the server and platform software as the upper computer, which can monitor a variety of water quality parameters: temperature, pH, dissolved oxygen, transparency, etc.
