Generally includes the whole process of growing aquatic products from offspring under artificial feeding management. The method can also comprise the steps of aquatic resource proliferation, rough culture, fine culture, high-density fine culture and the like in the broad sense. The rough culture is to put the fries in the middle and small natural water areas and to culture the aquatic products by the natural baits, such as fish culture in lakes and reservoirs, shellfish culture in shallow sea, and the like. The intensive culture is to culture aquatic products in a small water body by a bait casting and fertilizing method, such as fish culture in a pond, fish culture in a net cage, rail culture and the like. The high-density fine culture adopts methods of running water, temperature control, oxygenation, feeding of high-quality baits and the like, and the high-density culture is carried out in a small water body, so that high yield, such as running water high-density fish culture, shrimp culture and the like, is obtained.

The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, in an embodiment of the present invention, an intelligent device control method based on aquaculture includes:

S1: setting a culture space of the aquaculture corresponding to different required dissolved oxygen densities based on different types of aquaculture, and distributing the culture space into at least one or more required dissolved oxygen areas, wherein the aquaculture comprises freshwater aquaculture and seawater aquaculture;

S2: acquiring associated data in each dissolved oxygen area, generating a corresponding adjusting instruction of the dissolved oxygen area according to the associated data, and executing the corresponding adjusting instruction to the dissolved oxygen area, wherein the associated data comprises water temperature information, air pressure information and water quality information, and the adjusting instruction comprises adjusting the temperature of the dissolved oxygen area and limiting the feeding amount of the dissolved oxygen area;

S3: collecting a water sample in the dissolved oxygen area by adopting an ion sensor based on a preset period, detecting dissolved oxygen of the water sample, recovering the water sample to a detection position by adopting an adaptive film preset by the ion sensor according to an dissolved oxygen electrode method, separating impurities in the water sample, performing electrode reduction by adopting the adaptive film, generating a dissolved oxygen rate corresponding to the current intensity ratio according to the current intensity ratio output by the ion sensor, and judging whether the dissolved oxygen rate is in a preset balance interval;

S4: if not, executing corresponding different instructions to each dissolved oxygen area according to the condition that the dissolved oxygen rate exceeds the preset balance interval or is lower than the preset balance interval, stirring the sediment in the dissolved oxygen area according to the preset time period by using a stirring device preset at the bottom of the dissolved oxygen area when the dissolved oxygen rate exceeds the preset balance interval, promoting the sediment to decompose the sediment, and carrying out pressurizing treatment on water flow by using a submersible stirrer preset at the periphery of the dissolved oxygen area when the dissolved oxygen rate is lower than the preset balance interval, reducing the bubble diameter of the water body section in the dissolved oxygen area, increasing the rotating speed of the submersible stirrer, and introducing pure oxygen into the dissolved oxygen area through a preset oxygen expanding pipe.

In this embodiment, based on the existence of different types of aquaculture (including freshwater aquaculture and mariculture) in the aquaculture pond, the intelligent device sets corresponding different cultivation spaces with different dissolved oxygen densities required by different aquaculture, classifies the different cultivation spaces into at least one or more dissolved oxygen areas (including oxygen-enriched areas, oxygen-consuming areas and oxygen-deficient areas), and requires different dissolved oxygen density spaces for the long-term survival of different aquaculture, so the intelligent device generates currently corresponding required adjustment instructions (including adjusting the temperature of the dissolved oxygen areas and limiting the feeding amount of the dissolved oxygen areas) of the dissolved oxygen areas according to the associated data (including water temperature information, barometric information and water quality information) in each dissolved oxygen area, and executes the corresponding adjustment instructions to the dissolved oxygen areas as a method for balancing the dissolved oxygen density in the dissolved oxygen areas for the first time; the system collects partial water samples by controlling an ion sensor in an dissolved oxygen area based on a preset period, adopts an dissolved oxygen electrode method to carry out dissolved oxygen detection on the partial water samples, utilizes an adaptive film arranged in the ion sensor to separate the partial water samples from liquid, ions and other interfering substances, carries out electrode cathode end reduction through the adaptive film, and effectively measures the dissolved oxygen rate in the current dissolved oxygen water domain under the condition of no aeration by adopting the ion sensor and the dissolved oxygen electrode method to carry out the electrode cathode end reduction, so that the current value obtained by the ion sensor is replaced to obtain the dissolved oxygen rate in the partial water samples, for example, the preset current value of the ion sensor is 10A = 1 percent of the dissolved oxygen rate, when the current intensity generated by the ion sensor is 56A, the corresponding water sample dissolved oxygen rate is 5.6 percent, and when the current intensity generated by the ion sensor is 220A, the corresponding water sample dissolved oxygen rate is 22 percent, and the dissolved oxygen rate in the current dissolved oxygen water domain can be effectively measured under the condition of no aeration by adopting the ion sensor and the adaptive film to filter the dissolved oxygen rate after the impurity is filtered, and the accuracy of the dissolved oxygen is improved; the system judges whether the tested dissolved oxygen rate is in a preset dissolved oxygen balance interval or not so as to execute corresponding different steps; for example, when the oxygen dissolution rate obtained by the test is 15%, and the preset oxygen dissolution balance interval is 10% -20%, that is, the system determines that the current oxygen dissolution rate is within the preset oxygen dissolution balance interval, and does not need to execute any instruction for adjusting the oxygen dissolution rate on the oxygen dissolution area; for example, when the dissolved oxygen rate obtained by the test is 21%, and the preset dissolved oxygen balance interval is 10% -20%, the system determines that the current dissolved oxygen rate is not in the preset dissolved oxygen balance interval and is higher than the preset dissolved oxygen balance interval, that is, the system uses a stirring device preset at the bottom of the dissolved oxygen area to stir the substrate sludge in the dissolved oxygen area according to the preset time period, so as to promote the substrate sludge in the dissolved oxygen area to promote the substrate to be continuously decomposed, thereby improving the speed of water quality change and reducing the dissolved oxygen rate in the dissolved oxygen area; for example, when the oxygen dissolution rate obtained by the test is 9% and the preset oxygen dissolution balance interval is 10% -20%, the system determines that the current oxygen dissolution rate is not in the preset oxygen dissolution balance interval and is lower than the preset oxygen dissolution balance interval, the system uses a submersible mixer preset at the periphery of the oxygen dissolution area to carry out pressurization treatment on water flow at the moment, the bubble diameter of the water body section in the oxygen dissolution area is reduced, the contact probability of the bubbles and water is increased, oxygen is fully dissolved in the water, the oxygen transfer rate is greatly improved, the dissolved oxygen in the water is effectively increased, and the stirring rotation speed of the submersible mixer is simultaneously improved because the oxygen is a gas which is relatively insoluble in the water, and the rotation speed of the water flow can be improved through the mixer at the moment, so that the contact area of the pure oxygen and the water is improved, and the pure oxygen can be effectively dissolved in the water.

In this embodiment, further, if the dissolved oxygen rate is in the preset balance interval, the ion sensor is controlled to collect dissolved oxygen rate data according to a preset period,

It will be appreciated that since different aquaculture species may be grown in the dissolved oxygen region, different coefficients α may be set depending on the aquaculture species grown in the region.

In this embodiment, the intelligent device detects the dissolved oxygen rate of the dissolved oxygen area and the reference area based on a preset acquisition period, when the dissolved oxygen rate at the current moment is in a preset balance interval, the data acquisition is continuously performed on the ion sensor, the change rate Δv of the dissolved oxygen is required to be monitored, when the change rate Δv of the dissolved oxygen is greater than the preset first threshold v, the change of the dissolved oxygen rate at the moment is too fast, the data acquisition period of the ion sensor is controlled to be reduced, so that the change condition of the dissolved oxygen area is favorably monitored in time, the accuracy of the monitoring of the dissolved oxygen rate is improved, the abnormality of the dissolved oxygen rate in water is monitored in time, and early warning is performed under the condition that the preset condition is met, so that a user can intervene in time when required, or the corresponding device is controlled, so that the dissolved oxygen rate is stabilized in a reasonable interval.

It is understood that the reference area is an area of the anhydrous culture, and may be one or more small areas isolated from the culture space, for indicating dissolved oxygen consumption data when the anhydrous culture is used for indicating that the dissolved oxygen consumption is mainly determined by the environment; further, when the reference area is one, the reference area can be arranged in the middle area of the cultivation space, when the reference areas are multiple, the reference areas can be respectively arranged adjacent to the cultivation areas, so that the accuracy of differential detection of the dissolved oxygen is improved, and each reference area provides more accurate reference data for the adjacent cultivation areas.

Specifically, the reference area is only required to acquire the dissolved oxygen rate in the reference area by adopting an ion sensor, and the reference area can specifically acquire the change condition of the dissolved oxygen rate under the influence of natural factors because the reference area is not influenced by the aquaculture; the aquaculture is likely to be divided into freshwater aquaculture and mariculture except the reference area, so that the change conditions of the dissolved oxygen in the dissolved oxygen area are different, a plurality of ion sensors are arranged in the dissolved oxygen area and used for testing the change conditions of the dissolved oxygen in each corner of the dissolved oxygen area, the average value of the change conditions of the dissolved oxygen in each corner is taken as the current dissolved oxygen of the dissolved oxygen area, the required consumed dissolved oxygen in one period when the aquaculture exists in the whole dissolved oxygen area can be obtained, and the dissolved oxygen consumption rate in the area can be obtained by subtracting the dissolved oxygen in the reference area from the dissolved oxygen in the dissolved oxygen area and removing environmental factors.

It should be noted that the sensor placed in the reference area is an independent single sensor, and is especially used for testing the change condition of the dissolved oxygen rate except for the aquaculture, and is not affected by the dissolved oxygen area; the plurality of sensors are arranged in the dissolved oxygen area, and various aquaculture objects such as freshwater aquaculture objects, seawater aquaculture objects and the like exist in the dissolved oxygen area, so that the dissolved oxygen rate of the whole dissolved oxygen area is different, and the number of the sensors can be removed to be used as the average dissolved oxygen rate of the dissolved oxygen area according to a plurality of dissolved oxygen values acquired by the plurality of sensors.

In this embodiment, based on different types of aquaculture, setting a cultivation space of the aquaculture corresponding to a required different dissolved oxygen density, and distributing the cultivation space into at least one or more required dissolved oxygen areas in step S1 includes:

S11: identifying a concentration of a reducing substance in the farming space;

S12: judging whether the concentration of the reducing substance is larger than a preset concentration threshold value or not;

S13: if so, classifying the oxygen dissolving area of the culture space based on the concentration of the reducing substances, wherein the oxygen dissolving area comprises an oxygen enrichment area, an oxygen consumption area and an oxygen shortage area, the reducing substances with the lowest concentration belong to the oxygen enrichment area, the reducing substances with the highest concentration belong to the oxygen shortage area, and the reducing substances with the middle concentration belong to the oxygen consumption area.

In this embodiment, the intelligent device determines whether the concentration of the reducing substance exceeds a standard according to a preset concentration threshold value by identifying the concentration of the reducing substance (a great amount of reducing substance is generated by anaerobic decomposition of the excrement or part of remains of the cultured animal) existing in the culture space, so as to execute corresponding different steps; for example, if the intelligent device detects that the concentration of the reducing substance in the culture space is 60% and the preset concentration threshold is 70%, the intelligent device determines that the concentration of the reducing substance in the culture space is not out of standard, and a plurality of dissolved oxygen areas are not classified in the culture space but are uniformly set as oxygen-enriched areas; for example, when the intelligent device detects that the concentration of the reducing substance in the cultivation space is 80% and the preset concentration threshold value is 70%, the intelligent device determines that an oxygen-dissolved area with the concentration of the reducing substance exceeding the standard exists in the cultivation space, and classifies the single oxygen-dissolved area of the cultivation space according to the concentration of the reducing substance.

In this embodiment, the step S2 of obtaining the associated data in each dissolved oxygen area and generating the corresponding adjustment instruction for the dissolved oxygen area according to the associated data includes:

s21: acquiring water quality parameters in each dissolved oxygen area by using a preset water quality sensor, and reading the water quality parameters to acquire corresponding water quality transparency;

s22: judging whether the water quality transparency is within a preset parameter range or not;

s23: if not, executing corresponding different instructions on each dissolved oxygen area according to different aquaculture objects in each dissolved oxygen area, when the aquaculture objects belong to freshwater aquaculture objects, controlling the water flow of the dissolved oxygen areas in a running water aquaculture mode by using preset drainage measures, controlling the temperature of the dissolved oxygen areas in a required range corresponding to the freshwater aquaculture objects in a water body exchange mode, and when the aquaculture objects belong to the seawater aquaculture objects, controlling the water flow of the dissolved oxygen areas in a still water aquaculture mode by using a preset closed circulating water system, and limiting the feeding amount of the dissolved oxygen areas according to the aquaculture amount of the seawater aquaculture objects.

In this embodiment, the intelligent device uses a water quality sensor preset in water to collect water quality parameters in each dissolved oxygen area, and can collect water quality transparency of each dissolved oxygen area by reading the water quality parameters, and judges whether the water quality transparency meets the standard according to a preset parameter range so as to execute corresponding different steps; for example, when the intelligent device detects that the water quality transparency of a certain dissolved oxygen area is 20 cm and the preset parameter range is 20-30 cm, the intelligent device can judge that the water quality transparency of the dissolved oxygen area is in the preset parameter range, and the intelligent device can judge that the water quality of the dissolved oxygen area belongs to thin water with light water quality and light color, is light green or light yellow, has daily change and month change and has excellent dissolved oxygen condition; for example, when the intelligent device detects that the water quality transparency of a certain dissolved oxygen area is 15 cm and the preset parameter range is 20-30 cm, the intelligent device can judge that the water quality transparency of the dissolved oxygen area is not in the preset parameter range, at the moment, the intelligent device can execute corresponding different instructions on each dissolved oxygen area according to the aquatic products in different dissolved oxygen areas, when the aquatic products belong to the freshwater aquaculture, the water flow of the dissolved oxygen area is controlled in a running water aquaculture mode by applying preset drainage measures, the temperature of the dissolved oxygen area is controlled in a required range corresponding to the freshwater aquaculture in a water exchange mode, and the water quality and the temperature of the dissolved oxygen area are improved to ensure that the water sources of the dissolved oxygen area of the freshwater aquaculture are full and the water quality is good; when the aquaculture belongs to the mariculture, the water flow of the dissolved oxygen area is controlled in a still water culture mode by using a preset closed circulating water system, the feeding amount of the dissolved oxygen area is limited according to the culture amount of the mariculture, and the swimming speed and the metabolism speed of the aquaculture are slowed down by reducing the water flow speed and limiting the feeding amount of the aquaculture, so that the water quality is improved.

In this embodiment, before step S3 of collecting the water sample in the dissolved oxygen area by using the ion sensor based on the preset period, the method includes:

s301: acquiring illuminance when sunlight passes through the dissolved oxygen area by using a preset photosensitive sensor;

S302: judging whether the illuminance reaches a preset depth;

S303: if so, obtaining the dissolved oxygen rate of each dissolved oxygen area, when the dissolved oxygen rate of the dissolved oxygen area is too high, releasing a preset plant pigment on the surface layer of the dissolved oxygen area to raise the water level of the dissolved oxygen area, and when the dissolved oxygen rate of the dissolved oxygen area is too low, heating the temperature of the dissolved oxygen area to a preset temperature range by adopting a preset hydroelectric device, wherein the plant pigment comprises terramycin or tetracycline.

In this embodiment, the intelligent device obtains illuminance generated when sunlight irradiates the dissolved oxygen area by applying a photosensitive sensor preset in water, and determines whether the illuminance can reach a preset depth, so as to execute corresponding different steps; for example, the intelligent device detects that the illuminance of the dissolved oxygen area is 30 cm through the photosensitive sensor, and the preset depth is 20 cm, namely the intelligent device can judge that the illuminance can reach the preset depth, at the moment, the intelligent device can acquire the dissolved oxygen rate in the dissolved oxygen area, when the intelligent device judges that the dissolved oxygen rate of the current dissolved oxygen area is too high, the intelligent device can release preset phytochrome (terramycin or tetracycline) on the surface layer of the dissolved oxygen area, so that the aim of shielding sunlight is achieved, photosynthesis of the algae group is limited, the dissolved oxygen rate in the dissolved oxygen area is reduced, when the intelligent device judges that the dissolved oxygen rate of the current dissolved oxygen area is too low, the intelligent device can adopt preset hydropower equipment to heat the water temperature of the dissolved oxygen area to 25-28 ℃ which is most suitable for photosynthesis, the effect of photosynthesis is improved, and the dissolved oxygen rate in the dissolved oxygen area is improved; for example, the intelligent device detects that the illuminance received by the dissolved oxygen area is 10 cm through the photosensitive sensor, and the preset depth is 20 cm, that is, the intelligent device can determine that the illuminance cannot reach the preset depth, at this time, the intelligent device determines that the sunlight cannot penetrate the water level of the dissolved oxygen area, and cannot balance the dissolved oxygen rate of the dissolved oxygen area through the illuminance.

In this embodiment, acquiring the associated data in each dissolved oxygen area, generating a corresponding adjustment instruction for the dissolved oxygen area according to the associated data, and executing the corresponding adjustment instruction for the dissolved oxygen area, before step S2, includes:

S202: judging whether the environmental parameters are larger than a preset parameter threshold value or not;

s203: if not, adjusting the corresponding dissolved oxygen area with each environmental parameter larger than the preset parameter threshold based on a preset priority order, wherein the priority order is specifically the optimal dissolved oxygen content, the suboptimal PH value content and the third optimal ammonia nitrogen content, and the adjustment is specifically to control a preset oxygenator to oxygenate the corresponding dissolved oxygen area and control a preset administration machine to administer medicine to the corresponding dissolved oxygen area.

In this embodiment, the intelligent device determines whether each environmental parameter (including the dissolved oxygen content, the PH value content, and the ammonia nitrogen content) is greater than a preset parameter threshold by collecting each environmental parameter in each dissolved oxygen area, so as to execute a corresponding step; for example, when the intelligent device obtains that the dissolved oxygen content of the dissolved oxygen area is 10mg/L and the preset parameter threshold of the dissolved oxygen content is 20mg/L, the intelligent device can determine that the dissolved oxygen content belonging to the environmental parameter is not greater than the preset parameter threshold, that is, the intelligent device can oxygenate the corresponding dissolved oxygen area by using the preset oxygenator at the moment so as to improve the dissolved oxygen content in the dissolved oxygen area; for example, the intelligent device obtains that the PH value content of the dissolved oxygen area is 50mg/L and the preset ammonia nitrogen content is 40mg/L, then the intelligent device can judge that the ammonia nitrogen content belonging to the environmental parameter exceeds the preset parameter threshold, namely, the intelligent device can apply the preset dosing machine at the side of the culture pond to carry out the throwing of the alkali-reducing medicine to the dissolved oxygen area so as to reduce the ammonia nitrogen content in the dissolved oxygen area and avoid the water quality reduction or the water transparency reduction in the dissolved oxygen area.

In this embodiment, before step S201 of adjusting the corresponding dissolved oxygen area with the environmental parameters greater than the preset parameter threshold based on the preset priority, the method includes:

s2011: capturing the aquaculture in each dissolved oxygen area by using a preset scanner;

S2012: judging whether the aquaculture exists in an oxygen dissolving area needing to be adjusted;

S2013: if so, identifying that the aquaculture is in a specific direction of an oxygen dissolving area which needs to be adjusted, and fishing the aquaculture based on the specific direction.

In this embodiment, the intelligent device captures the aquaculture in the dissolved oxygen area by applying a scanner preset in water, so as to determine whether the aquaculture exists in the dissolved oxygen area, so as to execute the corresponding steps; for example, if the intelligent device captures that no aquaculture exists in the dissolved oxygen area, the intelligent device can collect water quality information of the dissolved oxygen area at the moment and execute a corresponding adjusting instruction to adjust environmental parameters of the dissolved oxygen area, and because executing the adjusting instruction when the aquaculture exists in the dissolved oxygen area easily causes death of the aquaculture, whether the aquaculture exists in the dissolved oxygen area needs to be confirmed in advance; for example, if the smart device captures that there is an aquaculture in the dissolved oxygen area, then the smart device needs to identify which orientation of the aquaculture is in the dissolved oxygen area, and salvage the aquaculture based on the specific orientation, so as to avoid death of the aquaculture when adjusting the environmental parameters of the dissolved oxygen area.

In this embodiment, according to the dissolved oxygen electrode method, the water sample is recovered to the detection position through an adaptive membrane preset by the ion sensor, the impurities in the water sample are separated, and electrode reduction is performed through the adaptive membrane, and the formula is as follows:

Wherein F _dds is the dissolved oxygen value in the water sample, the unit is mg/L, F _d is the dissolved oxygen value at normal temperature and normal pressure, the unit is mg/L, P is the atmospheric pressure, the unit is KPa, and h is the ratio of the atmospheric pressure sigma to the standard atmospheric pressure 101.325 KPa.

It should be noted that, when the concentration of oxygen molecules in water is related to the salinity of water and the salt content concentration of the water sample to be measured is less than 35g/L, it can be considered that the dissolved oxygen is in a linear relation with the salinity of water, the concentration of the dissolved oxygen decreases with the rise of the salinity, and the dissolved oxygen test of the water sample needs to be recalibrated, and the calibration formula is as follows:

F_dds2＝F_d-xΔF_d

Wherein F _dds2 is the saturated dissolved oxygen value of the water sample, and the unit is mg/L; f _d is saturated dissolved oxygen value at normal temperature and normal pressure, and the unit is mg/L; x is the salt content of the water sample, and DeltaF _d is the reduction value of dissolved oxygen caused by 1g/L of salt.

In this embodiment, a stirring device preset at the bottom of the dissolved oxygen area is used to stir the bottom mud in the dissolved oxygen area according to a preset period of time, so as to promote the bottom mud to decompose the bottom mud, and when the dissolved oxygen rate is lower than the preset balance interval, after the step of pressurizing the water flow by using a submersible mixer preset at the periphery of the dissolved oxygen area, the method includes:

In this embodiment, the system rechecks the dissolved oxygen area after the dissolved oxygen rate is controlled, sets the dissolved oxygen rates in a plurality of different time points within a certain period, generates a treated dissolved oxygen rate interval of the dissolved oxygen area based on the dissolved oxygen rates, and then determines whether the treated dissolved oxygen rate interval is within a preset dissolved oxygen interval value, and correspondingly executes the steps of increasing the dissolved oxygen rate or reducing the dissolved oxygen rate; for example, when the dissolved oxygen rate of the dissolved oxygen area is too high, the release amount of the organic weak acid sodium salt is controlled based on the attenuation factor by releasing the preset organic weak acid sodium salt to the dissolved oxygen area, the release amount is correspondingly reduced along with the reduction of the attenuation factor, and the release of the organic weak acid sodium salt is stopped when the dissolved oxygen rate is reduced to a preset balance interval; for example, when the oxygen dissolution rate of the oxygen dissolution area is too low, the release density of the probiotic bacteria and the algae are controlled based on the attenuation factor by releasing the preset probiotic bacteria to the oxygen dissolution area and releasing the preset algae to the oxygen dissolution area, and the release density correspondingly decreases along with the decrease of the attenuation factor until the oxygen dissolution rate is increased to a preset balance interval, and the release of the probiotic bacteria and the algae is stopped.

The sodium humate can reduce the transparency of water by releasing sodium humate, bacillus and chlorella into the culture environment, so as to reduce the photosynthesis intensity, and the bacillus can decompose oxygen-consuming molecules of the water and remove redundant nitrogen from the water, so as to reduce the ammonia nitrogen content in the culture environment, and the chlorella has good photosynthesis, can release a large amount of available oxygen in the water and improve the dissolved oxygen of the water; the dissolved oxygen density of the culture environment is controlled to be optimal through the means so as to ensure that the aquaculture can survive for a long time and adapt to the culture environment.

And the execution module 40 is configured to execute corresponding different instructions to each dissolved oxygen area if the dissolved oxygen rate exceeds the preset balance interval or is lower than the preset balance interval, stir the bottom mud in the dissolved oxygen area according to a preset time period by using a stirring device preset at the bottom of the dissolved oxygen area when the dissolved oxygen rate exceeds the preset balance interval, promote the bottom mud to decompose the bottom mud, and perform pressurization treatment on water flow by using a submersible stirrer preset at the periphery of the dissolved oxygen area when the dissolved oxygen rate is lower than the preset balance interval, reduce the bubble diameter of the water body section in the dissolved oxygen area, increase the rotation speed of the submersible stirrer, and introduce pure oxygen into the dissolved oxygen area through a preset oxygen expansion pipe.

the judging module 30 collects partial water samples by controlling an ion sensor in an oxygen dissolving area based on a preset period, adopts an oxygen dissolving electrode method to carry out oxygen dissolving detection on the partial water samples, utilizes an adaptive film arranged in the ion sensor to filter the partial water samples, separates the partial water samples from liquid, ions and other interference substances, carries out electrode cathode end reduction through the adaptive film, and generates current intensity in a stable state in proportion to the oxygen dissolving rate, so that the current value obtained by the ion sensor is replaced to obtain the oxygen dissolving rate in the partial water samples, if the preset current value of the ion sensor is 10 A=1% of the oxygen dissolving rate, when the current intensity generated by the ion sensor is 56A, the corresponding water sample oxygen dissolving rate is 5.6%, and when the current intensity generated by the ion sensor is 220A, the corresponding water sample oxygen dissolving rate is 22%, and can effectively measure the oxygen dissolving rate in the current oxygen dissolving water domain under the condition of no aeration by adopting the ion sensor and the adaptive film method to filter the oxygen dissolving rate, and the accuracy of the impurity is improved after the oxygen dissolving is tested; the system judges whether the tested dissolved oxygen rate is in a preset dissolved oxygen balance interval or not so as to execute corresponding different steps; for example, when the oxygen dissolution rate obtained by the test is 15%, and the preset oxygen dissolution balance interval is 10% -20%, that is, the system determines that the current oxygen dissolution rate is within the preset oxygen dissolution balance interval, and does not need to execute any instruction for adjusting the oxygen dissolution rate on the oxygen dissolution area; for example, when the oxygen dissolution rate obtained by the test is 21% and the preset oxygen dissolution balance interval is 10% -20%, the system determines that the current oxygen dissolution rate is not within the preset oxygen dissolution balance interval and is higher than the preset oxygen dissolution balance interval, that is, the executing module 40 uses the stirring device preset at the bottom of the oxygen dissolution area to stir the substrate sludge in the oxygen dissolution area according to the preset time period, so as to promote the substrate sludge in the oxygen dissolution area to promote the substrate to be decomposed continuously, thereby improving the speed of water quality change and reducing the oxygen dissolution rate in the oxygen dissolution area; for example, when the oxygen dissolution rate obtained by the test is 9% and the preset oxygen dissolution balance interval is 10% -20%, the system determines that the current oxygen dissolution rate is not in the preset oxygen dissolution balance interval and is lower than the preset oxygen dissolution balance interval, the system uses a submersible mixer preset at the periphery of the oxygen dissolution area to carry out pressurization treatment on water flow at the moment, the bubble diameter of the water body section in the oxygen dissolution area is reduced, the contact probability of the bubbles and water is increased, oxygen is fully dissolved in the water, the oxygen transfer rate is greatly improved, the dissolved oxygen in the water is effectively increased, and the stirring rotation speed of the submersible mixer is simultaneously improved because the oxygen is a gas which is relatively insoluble in the water, and the rotation speed of the water flow can be improved through the mixer at the moment, so that the contact area of the pure oxygen and the water is improved, and the pure oxygen can be effectively dissolved in the water.
