Early warning method, apparatus, and system for nitrogen concentration in industrialized aquaponic circulating water

An early warning method for a nitrogen concentration in industrialized aquaponic circulating water, comprising:

• obtaining video data of a sensitive fish farming container, wherein the video data comprises a monitored movement behavior of a sensitive fish in the sensitive fish farming container, and the sensitive fish farming container is in communication with a farming pond of an aquaponic system;
• processing the video data using an object detection model and obtaining a behavior activity of the sensitive fish according to a processing result;
• processing the behavior activity using a neural network model to obtain a nitrogen concentration grade of the farming pond of the aquaponic system;
• determining whether to send nitrogen concentration early warning information based on the nitrogen concentration grade;
• and
• setting a range of a total nitrogen concentration in water to 0-20 mg/L, configuring a nitrogen concentration grade for every 5 mg by using four colors of blue, yellow, orange, and red to represent nitrogen concentrations from low to high, wherein 0-5 mg/L is represented by blue, 5 mg/L-10 mg/L is represented by yellow, 10 mg/L-15 mg/L is represented by orange, and 15 mg/L-20 mg/L is represented by red, and sending the nitrogen concentration early warning information when a monitored nitrogen concentration grade reaches yellow, orange, or red, to notify a worker of taking measures of replacing water in the farming pond of the aquaponic system in time.
