Embodiment 1

[0047] Such as figure 1 The shown embodiment is a kind of aeration control device used in the freshwater aquaculture system, including a microprocessor 1, a memory 2, a first aerator 3, 10 detection devices 4 in the pond, and a The second aerator 5 on the pond; the pond is provided with a track, and the track is provided with an electric trolley 6, and the electric trolley is connected with the second aerator; each detection device includes a dissolved oxygen sensor 41 and a water temperature sensor stretched into the water 42; the microprocessor is respectively connected with the memory, the first aerator, each dissolved oxygen sensor, each water temperature sensor, the second aerator and the electric trolley.

[0048] Each detection device is arranged in a matrix. The first aerator is located on the water surface in the middle of the pond, and the track is arranged along the edge of the pond and is oblong.

[0049] Such as figure 1 , image 3 As shown, the electric troll...

Embodiment 2

[0073] Embodiment 2 includes all structures and step parts in Embodiment 1, and Embodiment 2 also includes such as figure 1 The light sensor 7 and alarm 8 shown are all electrically connected to the microprocessor.

[0074] The light threshold C is set in the memory, and the light sensor detects the light intensity signal value P. When P>C, the microprocessor controls the first oxygen increase control process to terminate, and executes the second oxygen increase control process;

[0075] The second aeration control process comprises the steps:

[0076] The microprocessor controls the first aerator and the second aerator to start working at the same time, and the working time is 3.5T. Among them, the second aerator moves along the upper surface of the pond to increase oxygen under the drive of the electric trolley; the second aerator After the control process ends, the microprocessor controls and executes the first oxygen increasing control process.

Embodiment 3

[0078] Embodiment 3 includes all structures and method steps in embodiment 1, and embodiment 3 also includes such as figure 1 Shown light sensor 7 and alarm 8, light sensor and alarm are all electrically connected with microprocessor;

[0079] The following steps are also included between steps 100 and 200 of Embodiment 1: the light sensor detects the light intensity signal x(t), and the microprocessor extracts x(t) in the time period t 1 Signal x(t) within t1 , S(t)′ in time period t 1 The signal S(t) within t1 ;if x(t) t1 and S(t) t1 There is no proportional relationship between the changes, then the microprocessor controls the alarm to alarm. t 1 for 10 minutes.

[0080] There is no proportional relationship, indicating that there is a fault in the light sensor or the dissolved oxygen sensor in the detection device. After the alarm, the staff will check and repair it.

Abstract

The invention discloses an oxygenation control device and a control method in a fresh water culture system; the oxygenation control device comprises a microprocessor, a memory, a first aerator arranged in a pond, a plurality of detectors, and a second aerator arranged on the pond; the pond is provided with a track having an electric motor-driven cart; the electric motor-driven cart is connected with the second aerator; each detector comprises a dissolved oxygen sensor and a water temperature sensor extending into water; the microprocessor is respectively connected with the memory, the first aerator, each dissolved oxygen sensor, each water temperature sensor, the second aerator and the electric motor-driven cart; the oxygenation control device and the control method can dynamically oxygenate in real time, so the water oxygen content is stable, thus providing guarantees for fishes to grow in healthy.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aeration control device and a control method used in a freshwater aquaculture system, which have high detection accuracy and can effectively ensure stable oxygen content in water. Background technique [0002] Dissolved oxygen is an important water quality index of fishery water, and the dissolved oxygen status has an important impact on water quality and the growth of cultured organisms. With the rapid development of pond aquaculture, pond dissolved oxygen, as a water environment factor that must be controlled in aquaculture waters, has been paid more and more attention. At present, most of the dissolved oxygen in ponds is measured at fixed times and at fixed points. The identification of the dynamic changes of dissolved oxygen is mainly based on the observation of the changes in the breeding biological activities in the pond by the breeding managers. The above-mentioned...
