Intelligent feed supplying control method and system capable of achieving automatic calibration

Abstract

The invention discloses an intelligent feed supplying control method and system capable of achieving automatic calibration. The method comprises steps of setting adjacent fish ponds to be groups and periodically calculating reference dissolved oxygen data of each group; acquiring dissolved oxygen data of a to-be-fed fish pond, and if the a difference value between the dissolved oxygen data and thereference dissolved oxygen data thereof exceeds a preset threshold, determining that data is abnormal and using the reference dissolved oxygen data as the acquired dissolved oxygen data; if the acquired dissolved oxygen data reaches a satiation dissolved oxygen standard, carrying out satiation feeding on the fish pond; if the acquired dissolved oxygen data is lower than the satiation dissolved oxygen standard, carrying out oxygen supplementation on the fish ponds of the group; and after the acquired dissolved oxygen data reaches the satiation dissolved oxygen standard, carrying out satiationfeeding on the fish ponds. According to the invention, feed supplying control can be carried out in a matching manner according to dissolved oxygen data of fish ponds automatically; the utilization rate of the feed and the growth rate of aquatic life in the aquaculture processes are improved to be the optimal level; and even if dissolved information acquisition device data of a certain fish pond is changed suddenly, normal management and control of the fish pond will not be affected.

Description

technical field [0001] The invention relates to an intelligent aquaculture technology, in particular to an intelligent aquaculture feed feeding control technology. Background technique [0002] Dissolved oxygen is the lifeline for fish in water to survive. Dissolved oxygen is not only an essential substance to ensure the normal physiological function and healthy growth of prawns, but also an essential substance to improve water quality and bottom layer, and a key factor to maintain the smooth progress of nitrogen cycle. Aquatic animals live in water, and to carry out metabolism, the premise is that the dissolved oxygen in the water should be sufficient. Dissolved oxygen is closely related to the survival and growth of aquatic animals. High dissolved oxygen in water means that the water quality will be fertile, alive and refreshing. High dissolved oxygen in pool water can promote the appetite of farmed animals, improve the utilization rate of feed, and accelerate growth and ...

Problems solved by technology

If the water body is in a state of hypoxia, the food intake of fish will be significantly reduced, resulting in serious waste of feed, a significant increase in feed coefficient, resulting in an increase in breeding costs and low breeding benefits; and it will cause deterioration of the water environment. Excessive salt causes fish death and economic loss
