Abstract

The invention relates to the technical field of aquaculture oxygen aeration, and particularly discloses an oxygen aeration control device which comprises an electric control box. A power switch, an alternating-current contactor, a wiring terminal, a cell, a solar cell panel, an air temperature and humidity sensor and a controller are arranged on the electric control box, wherein the alternating-current contactor is used for controlling an oxygen aerator to be opened or closed, the wiring terminal is used for being connected with a power line, the solar cell panel is used for charging the cell, and the controller is arranged on the electric control box. The controller predicts a dissolved oxygen numerical value by processing a voltage value of the cell and air temperature and humidity values of the air temperature and humidity sensor and controls the alternating-current contactor according to the dissolved oxygen numerical value. According to the oxygen aeration control device, the dissolved oxygen numerical value can be predicted in advance, then, the oxygen aerator is controlled to be opened and closed according to the predicted result and the preset higher limiting value and the preset lower limiting value, the water dissolved oxygen value is not required to be directly detected, the hysteretic phenomenon of oxygen aeration can not occur, the oxygen aeration effect is good, the oxygen aeration efficiency is high, and the automation degree and the intelligentized degree are high.

Description

technical field [0001] The invention relates to the technical field of aquaculture aeration, in particular to an aeration control device. Background technique [0002] Dissolved oxygen refers to molecular oxygen dissolved in water or solution, which is an indispensable condition for the survival of aquatic animals and plants. When the concentration of dissolved oxygen is less than 3mg / l, the survival of aquatic animals such as fish will be affected. Therefore, oxygen control is of great significance in the field of aquaculture, and it can effectively promote aquaculture to high yield, high efficiency, high quality, safety, Healthy development is of great significance to the sustainable development of aquaculture. [0003] At present, with the continuous improvement of detection technology, more and more dissolved oxygen sensors are used in the existing aeration technology to detect the dissolved oxygen value of the water body, and the aerator is manually turned on or off ac...
