Automatic control oxygen filling system for aquaculture

Abstract

The invention discloses an automatic control oxygen filling system for aquaculture. The automatic control oxygen filling system comprises a dissolved oxygen meter, an automatic controller and an oxygen increasing device, wherein the dissolved oxygen meter is connected with the automatic controller, and is used for detecting the dissolved oxygen amount in the water of a culture pond in real time and transmitting detection signals into the automatic controller in real time; the automatic controller is used for processing according to the received detection signals of the dissolved oxygen amount; when the dissolved oxygen amount is judged to be lower than the set threshold value, a control signal is output, and the oxygen increasing device is started for increasing the oxygen; when the dissolved oxygen amount in the culture pond is judged to reach the set threshold value, the oxygen increasing device is stopped. The automatic control oxygen filling system for aquaculture can detect the dissolved oxygen amount in the water in real time by the dissolved oxygen meter, and transmits the detection signals into the automatic controller in real time; the automatic controller can be used for processing according to the preset program; the control signal is automatically output according to the received dissolved oxygen amount monitoring signals, so that the oxygen increasing device can be controlled to be started or stopped, and automatic oxygen increasing control can be further realized; compared with the existing manual detection and manual control oxygenation, the automatic control oxygen filling system for aquaculture has the characteristics of being accurate in control and having the real-time property.

Description

technical field [0001] The invention relates to an oxygenation system for aquaculture, in particular to an automatically controlled oxygenation system for aquaculture. Background technique [0002] Aeration and oxygenation supply oxygen from the bottom of the water, which can effectively prevent the formation of anaerobic layer at the bottom of the pool. Hydrogen sulfide and other harmful substances are oxidized, inhibit harmful microorganisms, activate the pond bottom, and enable the water body to maintain good water quality, so it is welcomed by aquaculture units. [0003] But at present, when people use aeration type oxygenation device to aerate the breeding pond, they usually first detect the amount of dissolved oxygen in the water through the corresponding detector. The aeration device is aerated and aerated, and the aeration-type aeration device is turned off after a certain period of time. [0004] Since there is no standard automatic control program in this control...

AI Technical Summary

Problems solved by technology

[0004] Since there is no standard automatic control program for this control method, it is difficult to monitor the dissolved oxygen in the water in the aquaculture pond in real time, and start the aeration type aeration device for aeration and oxygenation according to the monitoring results.

Sometimes it will cause delay of aeration and oxygenation, thus affecting the water quality of the water body in the culture pond, so that the aeration and oxygenation cannot achieve the desired effect
