Intelligent control oxygenation method based on three-dimensional dissolved oxygen map

Abstract

The invention discloses an intelligent control oxygenation method based on a three-dimensional dissolved oxygen map. Through the online monitoring of oxygen solubility of different positions and different depths in a fish pond, a distribution three-dimensional map is established based on a detected dissolved oxygen value to reflect a real dissolved oxygen value, thus the water quality dissolved oxygen regulation can be carried out well, the quality and output of aquatic products are improved, the risk of breeding is reduced, and the economic benefits of farmers are greatly increased.

Description

Technical field [0001] The invention relates to the technical field of aquaculture oxygenation, in particular to an intelligently controlled oxygenation method based on a three-dimensional dissolved oxygen map. Background technique [0002] In the current aquaculture industry, most farmers do not know the dissolved oxygen value in the aquaculture water body, and generally judge based on traditional experience or fixed nodes to detect the dissolved oxygen value at certain points to turn on or off the aeration pump. [0003] For fish ponds, due to the influence of light intensity, the dissolved oxygen in the fish pond water will show a certain vertical change pattern. Dissolved oxygen in fish ponds, under the influence of wind, biology, man-made factors, etc., will show that the level of changes is not uniform, so there is no fixed law for vertical changes, and horizontal changes will cause the overall distribution of dissolved oxygen in fish ponds to be uneven. . 1. Under the effe...

3. In fish ponds with water inlet and drainage systems, when water is injected, the dissolved oxygen value around the water injection port will change, and when drained, the dissolved oxygen value around the drain port will also change, making the dissolved oxygen value vary widely unpredictable

[0004] Uneven distribution will make the measured value of dissolved oxygen sensor not reflect the real value of dissolved oxygen in the current fish pond. When the real value meets the dissolved oxygen of the current fish pond but the measured value is lower than the real value, the automatic aerator will work, which is very difficult. To achieve the effect of energy saving

When the real value does not meet the dissolved oxygen of the current fish pond but the measured value is higher than the real value, the automatic aerator will not work, which will cause the fish to grow slowly, the survival rate will decrease, and the feed coefficient will increase. A large number of deaths, causing serious economic losses
