Embodiment 2

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

[0074] The oxygen threshold value C is set in the memory, and the oxygen concentration sensor detects the oxygen concentration 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 increasin...

Embodiment 3

[0078] Embodiment 3 includes all structures and method steps in embodiment 1, and embodiment 3 also includes such as figure 1 Shown oxygen concentration sensor 7 and alarm 8, oxygen concentration 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 oxygen concentration sensor detects the oxygen concentration 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, the microprocessor controls the alarm to alarm. t 1 for 10 minutes.

[0080] If there is no proportional relationship, it means that the oxygen concentration sensor or the dissolved oxygen sensor in the detection device is faulty. After the alarm, the staff will check and repair it.

Abstract

The invention discloses a real-time control device for dissolved oxygen for a pond and a control method thereof. The real-time control device comprises a microprocessor, a memory, a first aerator arranged in a pond, a plurality of detection devices, and a second aerator arranged above the pond. A track is arranged above the pond and a motor-driven carrier is arranged on the track and is connected with the second aerator. The pond has a rectangular shape; a conduit is arranged between one pair of corners of the pond; the two ends of the conduit extend into water and a water pump is arranged at the conduit. Each detection device includes a dissolved oxygen sensor and a water temperature sensor that extend into water. The microprocessor is electrically connected to the memory, the first aerator, all the dissolved oxygen sensors, all the water temperature sensors, the second aerator, the water pump and the motor-driven carrier. The control device and method have the following characteristics: dissolved oxygen in the pond can be controlled in real time and the dissolved oxygen content in the water is stable; and the healthy growth of the fish in water can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a real-time dissolved oxygen control device and control method for ponds that 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 control methods ...
