Embodiment 2

[0076] Embodiment 2 includes all structures and step parts in Embodiment 1, and Embodiment 2 also includes such as figure 1 Shown oxygen sensor 7 and alarm 8, oxygen sensor and alarm are all electrically connected with microprocessor.

[0077] The oxygen threshold C is set in the memory, and the oxygen sensor detects the oxygen concentration signal value P. When P>C, the microprocessor controls the termination of the first oxygen increase control process, and executes the second oxygen increase control process;

[0078] The second aeration control process comprises the steps:

[0079] 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 pro...

Embodiment 3

[0081] Embodiment 3 includes all structures and method steps in embodiment 1, and embodiment 3 also includes such as figure 1 Shown oxygen sensor 7 and alarm 8, oxygen sensor and alarm are all electrically connected with microprocessor;

[0082] The following steps are also included between steps 100 and 200 of embodiment 1: the oxygen 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.

[0083] If there is no proportional relationship, it means that the oxygen sensor or the dissolved oxygen sensor in the detection device is faulty. After the alarm, the staff will check and repair it.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device and method for controlling dissolved oxygen in a freshwater aquaculture water body with high detection accuracy and can effectively ensure stable oxygen content in the 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-mentione...
