Description

Technical Field

[0001] The present invention relates to the technical field of seahorse breeding, and in particular to an intelligent and controllable breeding device and method for seahorse circulating water. Background Art

[0002] Seahorse breeding belongs to the field of special marine biological breeding, involving the fields of seahorse-specific marine biological breeding and breeding, resources, protection, ornamental industry, functional food and medical materials. Seahorse is a traditional precious Chinese medicine. It has been recorded in my country for nearly two thousand years. The medicinal value of seahorse is very high. There is a saying among the people that "seahorse in the south is ginseng in the north". It has the effects of nourishing the kidney and strengthening yang, strengthening the heart and promoting labor, relaxing muscles and activating collaterals, removing phlegm and dispersing knots, relieving inflammation and fever, and relieving pain and stopping bleeding. It has been recorded in ancient medical books of all dynasties and all versions of my country's pharmacopoeia. Li Shizhen's "Compendium of Materia Medica" stated that seahorse has the effect of "warming the kidney and strengthening yang". In addition to being used directly for treatment, seahorse can also be used to make various medicines and health products. Currently, most seahorse farming farms use the same fish, abalone, and sea cucumber farming ponds for breeding. The breeding methods are not standardized and the survival rate is low, which has become a bottleneck in the market supply and demand. In 2023, the domestic marketed seahorse farming output will be about 30 million, with a production capacity of about 20 tons. The existing production capacity accounts for less than 10% of the market demand. Scarcity makes things expensive and the market price remains high.

[0003] The research and development of seahorse breeding in my country began in 1958. It has experienced several ups and downs. As a marine organism with high economic and medicinal value, the breeding industry of seahorses has achieved certain development in recent years. However, traditional seahorse breeding is limited by natural environmental conditions. For example, seahorses have strict requirements on water quality conditions such as salinity, water temperature, pH value and dissolved oxygen, and it is difficult to achieve precise control of the breeding environment. This has led to problems such as slow growth, low survival rate, and frequent diseases of seahorses. The water environment affects the survival and breeding of seahorses, which seriously restricts the sustainable development of seahorse breeding. Summary of the invention

[0020] S1. Treat the seawater entering the aquaculture workshop for recycling;

[0021] S2. Circulation treatment of water used in the breeding workshop. The circulation process of the circulating water is as follows:

[0022] The waste in the upper, middle and lower sections of the breeding pond will flow to the circulating water ground pipe through the segmented water collector;

[0023] The residual bait and feces at the bottom of the breeding pond are discharged from the breeding pond through the directional sewage discharger, and the sewage flowing out of the directional sewage discharger and the circulating water ground pipe flows to the combined water tank and flows into the filter through the circulating water outlet pipe;

[0024] In the filter, the dirt and circulating water are separated, the purified circulating water flows to the water collection tank, the separated dirt enters the dehydration solidification device for dehydration and solidification, the sewage separated by the dehydration solidification device is injected into the sewage pool, and the water in the sewage pool is transported to the biological pool;

[0025] The first water pump delivers half of the circulating water in the water collection pool to the biological pool. The water in the biological pool is regularly delivered to the decarbonation and oxygenation tower. The sewage precipitated at the bottom of the biological pool flows to the dehydration solidification device through the sewage outlet pipe.

[0026] The second water pump transports the remaining circulating water in the water collection tank to the decarbonization and aeration tower. The circulating water after the decarbonization and aeration tower is transported to the water regulating tank. The circulating water in the water regulating tank is transported to each breeding pond through the circulating water return pipe.

[0027] S3. Monitor the salinity in the aquaculture pond as follows:

[0028] The salinity sensor monitors the salinity in the breeding pool and transmits the salinity to the control module. The control module has a preset salinity. If the salinity in the breeding pool is lower than the preset salinity, the control module opens the seawater supply solenoid valve to add seawater to the water regulating pool to increase the salinity in the water regulating pool. If the salinity in the breeding pool is higher than the preset salinity, the control module opens the freshwater supply solenoid valve to add fresh water to the water regulating pool. After adjusting the salinity in the water regulating pool, the circulating water flows to each breeding pool through the circulating water return pipe to adjust the salinity in the breeding pool.

[0029] S4. Monitor the temperature in the breeding pond as follows:

[0030] The temperature sensor monitors the temperature in the breeding pool and transmits the temperature to the control module. The control module has a preset temperature. When the temperature in the breeding pool is lower than the preset temperature, the control module starts the heat exchanger and the water source heat pump. The water in the third water storage tank flows into the heat exchanger from the hot end inlet and flows out from the hot end outlet to the water source heat pump.

[0031] The water in the water collection tank flows into the heat exchanger from the cold end inlet and flows out from the cold end outlet to the water source heat pump; in the water source heat pump, the water discharged from the third water storage tank and the water discharged from the water collection tank are heat exchanged again; after the heat exchange, the water discharged from the third water storage tank flows to the breeding pond;

[0032] S5. Monitor the pH value in the breeding pond as follows:

[0033] The pH sensor monitors the pH value in the breeding pool and transmits the pH value to the control module. The control module has a preset pH value. If the pH value in the breeding pool is lower than the preset pH value, the control module controls the first doser to add alkaline substances to the water adjustment pool; if the pH value in the breeding pool is higher than the preset pH value, the control module controls the second doser to add acidic substances to the water adjustment pool; after adjusting the pH value in the water adjustment pool, the circulating water flows to each breeding pool through the circulating water return pipe to adjust the pH value in the breeding pool;

[0034] S6. Monitor the oxygen content in the culture pond as follows:

[0035] The oxygen content sensor monitors the oxygen content in the breeding pool and transmits the oxygen content to the control module. The control module has a preset oxygen content. If the oxygen content in the breeding pool is lower than the preset oxygen content, the control module controls the aeration device to start to increase the oxygen content in the water regulating pool. After adjusting the oxygen content in the water regulating pool, the circulating water flows to each breeding pool through the circulating water return pipe to adjust the oxygen content in the breeding pool.

[0036] S7. Monitor the concentrations of ammonia nitrogen and nitrite in the aquaculture pond as follows:

[0037] Ammonia nitrogen and nitrite monitoring sensors measure the ammonia nitrogen and nitrite concentrations in the breeding pond and transmit the ammonia nitrogen and nitrite concentrations to the control module. The control module has preset ammonia nitrogen and nitrite concentrations. If the ammonia nitrogen and nitrite concentrations in the breeding pond are higher than the preset ammonia nitrogen and nitrite concentrations, the control module controls the water flow rate of the biofilter bed to increase and increases the aeration volume of the biofilter bed.

[0038] Furthermore, it also includes the control of the LED lighting equipment in the breeding workshop. The light sensor and the spectrum sensor obtain the light intensity and spectrum data of the breeding workshop, and transmit the light intensity and spectrum data to the control module. The control module has preset light intensity and spectrum data. According to the preset light intensity and spectrum data, the control module adjusts the light intensity and spectrum of the LED lighting equipment so that the light intensity and spectrum of the breeding workshop meet the preset light intensity and spectrum data.

[0039] The breeding method also includes controlling the flow rate of water in the breeding pond, the flow controller adjusts the opening of its own valve according to the flow rate of water in the circulating water return pipe, and the flow rate of water in the circulating water return pipe of the flow controller is fed back to the control module, and the control module adjusts the pumping power of the return pump according to the preset water flow rate.

[0040] The advantages of the present invention are:

[0041] 1. By precisely controlling key parameters such as salinity, temperature, pH value, dissolved oxygen, ammonia nitrogen, nitrite, light and water flow of seahorse breeding water, all indicators can be met to achieve efficient breeding of seahorses, which can save land, energy, water and human resources.

[0042] 2. By integrating advanced water treatment technology, automated control and intelligent monitoring systems, high efficiency, high yield and high environmental protection standards are achieved in seahorse farming.

DETAILED DESCRIPTION

[0060] For example, see Figures 1 to 13The present invention provides an intelligent and controllable seahorse circulating water breeding equipment 100, which includes a plurality of breeding pools 1. A directional drainer 2 is connected to the bottom of each breeding pool 1. The directional drainer 2 is a hollow circular tube structure. A plurality of holes connected to the inner cavity are opened on the outer wall of the directional drainer 2. The residual bait and feces flow into the directional drainer 2 through the holes. The directional drainer 2 is placed horizontally on the bottom of the breeding pool 1 and is located between the pool and the edge of the pool to absorb the residual bait and feces in the breeding pool 1. The residual bait and feces do not need to rotate more than one circle and can be discharged immediately. The remaining bait and feces stay in the water for a short time and have a short flow path, so the remaining bait and feces are less damaged and decomposed, ensuring that the water quality is less polluted; each of the aquaculture ponds 1 is also provided with a segmented water sampler 3, which is a pipe vertically arranged in the aquaculture pond 1, the bottom of the pipe is connected to the circulating water pipe 4, the top surface of the pipe is open, and the top surface of the pipe is flush with the liquid surface of the aquaculture pond 1, and through holes 301 are respectively opened in the middle and lower sections of the pipe. The oil floating on the surface of the aquaculture pond 1 overflows into the segmented water sampler 3 through the top of the pipe, and the suspended matter in the water of the aquaculture pond 1 flows into the segmented water sampler 3 through the through hole 301 opened in the middle section of the pipe, and the remaining bait and feces at the bottom of the aquaculture pond 1 flows into the segmented water sampler 3 through the through hole 301 opened in the lower section of the pipe. A circulating water ground pipe 4 is connected, and the circulating water ground pipe 4 is arranged at the bottom of the breeding pond 1. The directional drain 2 and the circulating water ground pipe 4 in the same breeding pond 1 are commonly connected to a combined water tank 5, and the combined water tank 5 can balance the combined flow of the water outlet of the circulating water ground pipe 4 and the water outlet of the directional flow drain. The combined water tank 5 is connected to a circulating water outlet pipe 6, and the circulating water outlet pipe 6 is connected to a filter 7. The filter 7 is a static flow filter 7, and adopts a two-stage filtration method. The first stage is coarse filtration, and the filter screen has a specification of 100 meshes. The second stage is fine filtration, and the filter screen has a specification of 1200 meshes; and the static flow filter 7 is also connected to a backwash pump 8, and the backwash pump 8 is connected to a sump 9. The backwash pump 8 can take water in the sump 9 to backwash the filter screen of the static flow filter 7.

[0061] The filter 7 is connected to a water collection tank 9, and the water collection tank 9 is connected to a water treatment device 10 for circulating water treatment. The water treatment device 10 is used to perform biodegradation, decarbonation and oxygenation, and ultraviolet sterilization on the water in the water collection tank 9. The water treatment device is used to remove waste and pathogens in the water and keep the water clean. The water treatment device 10 is connected to a water regulating tank 11, and the water regulating tank 11 is connected to each breeding pool 1 through a circulating water return pipe. The end of the circulating water return pipe is connected in the tangential direction of the breeding pool 1, and the water in the circulating water return pipe flows into the breeding pool 1 along the tangential direction of the breeding pool 1;

[0062] The aquaculture equipment 100 also includes an aquaculture environment monitoring system 200, which can monitor key water quality parameters such as salinity, water temperature, pH value, dissolved oxygen, ammonia nitrogen, nitrite, etc. in real time. The data is collected through sensors, analyzed by computers or microcontrollers, and the return pump, aeration device and other equipment are automatically adjusted according to preset parameters.

[0063] The aquaculture environment monitoring system 200 includes a control module 12 and a salinity sensor 13, a temperature sensor 14, a pH sensor 15 and an oxygen content sensor 16 arranged in the aquaculture pond 1, wherein the salinity sensor 13, the temperature sensor 14, the pH sensor 15 and the oxygen content sensor 16 are all connected to the control module 12;

[0064] The aquaculture equipment 100 also includes a first water reservoir 17 for storing fresh water and a second water reservoir 18 for storing seawater. The seawater stored in the second water reservoir 18 is high-salinity seawater. The drainage end of the first water reservoir 17 is connected to the water regulating tank 11 through a first pipeline, and a fresh water supply solenoid valve 19 is provided on the first pipeline. The drainage end of the second water reservoir 18 is connected to the water regulating tank 11 through a second pipeline, and a seawater supply solenoid valve 20 is provided on the second pipeline. The fresh water supply solenoid valve 19 and the seawater supply solenoid valve 20 are both connected to the control module 12;

[0065] The salinity sensor 13 monitors the salinity in the culture pond 1 and transmits the salinity to the control module 12. The control module 12 has a preset salinity. If the salinity in the culture pond 1 is lower than the preset salinity, the control module 12 opens the seawater supply solenoid valve 20 to add seawater to the water regulating pond 11 to increase the salinity in the water regulating pond 11. If the salinity data is higher than the preset salinity data, the control module 12 opens the freshwater supply solenoid valve 19 to add fresh water to the water regulating pond 11. After adjusting the salinity in the water regulating pond 11, the circulating water flows to each culture pond 1 through the circulating water return pipe to adjust the salinity in the culture pond 1.

[0066] The aquaculture equipment 100 also includes a heat exchanger 21 and a third water reservoir 22 for storing seawater. The temperature of the seawater stored in the third water reservoir 22 is 30°C. The heat exchanger 21 has four ports, namely, a hot end inlet 211, a hot end outlet 212, a cold end inlet 213 and a cold end outlet 214. The third water reservoir 22 is connected to the hot end inlet 211, and the hot end outlet 212 is connected to a water source heat pump 23. The water source heat pump 23 is connected to the aquaculture pond 1, the water collection tank 9 is connected to the cold end inlet 213, and the cold end outlet 214 is connected to the water source heat pump 23. The water source heat pump 23 is also connected to a tailwater treatment tank 24. The water source heat pump 23 and the heat exchanger 21 are both connected to the control module 12.

[0067] For example, when the water temperature in the aquaculture pond 1 drops below 19°C, the water in the third water reservoir 22 flows into the heat exchanger from the hot end inlet 211 and flows out from the hot end outlet 212 to the water source heat pump 23; the water in the water collection tank 9 flows into the heat exchanger 21 from the cold end inlet 213 and flows out from the cold end outlet 214; in the heat exchanger 21, the water flowing out of the third water reservoir 22 exchanges heat with the water flowing out of the water collection tank 9, so that the water temperature of the seawater flowing out of the hot end outlet 212 drops to 2 1℃, the discharge water flowing out of the cold end outlet 214 rises to 28℃, and the water after the heat exchange flows to the water source heat pump 23 again; in the water source heat pump 23, the seawater discharged from the third water storage tank 22 and the discharge water discharged from the water collection tank 9 exchange heat again; after the heat exchange, the seawater discharged from the third water storage tank 22 flows to the breeding pond 1, at this time, the water temperature flowing to the breeding pond 1 is maintained at 19℃, and the water in the water collection tank 9 flows to the tail water treatment tank 24 after passing through the water source heat pump 23;

[0068] The breeding equipment 100 further includes a first doser 25 for adding alkaline substances to the water regulating pool 11 and a second doser 26 for adding acidic substances to the water regulating pool 11, and the first doser 25 and the second doser 26 are both connected to the control module 12;

[0070] Specifically, the filter 7 has a sewage discharge end and a liquid outlet end, the water collection tank 9 is connected to the liquid outlet end, and the sewage discharge end is connected to a dehydration solidification device 28. The function of the dehydration solidification device 28 is to further dehydrate and solidify the waste such as residual bait and feces separated by the solid-liquid separation of the static flow filter 7 to prevent the waste such as residual bait and feces from fermenting and corrupting and polluting the aquaculture water body and the environment, and the dehydrated and solidified waste such as residual bait and feces can also be used as high-quality fertilizer for crops;

[0071] The water treatment device 10 includes a biological pool and a decarbonation and aeration tower. The water collection pool 9 is connected to a first water pump 29 and a second water pump 30. The first water pump 29 is connected to a biological pool 31. A biological filter bed 32 is arranged in the biological pool 31. The second water pump 30 is connected to a decarbonation and aeration tower 33. The biological pool 31 is also connected to a decarbonation and aeration tower 33. The decarbonation and aeration tower 33 is connected to the water adjustment pool 11. Since the static flow filter 7 has the function of precipitating solids and liquids to separate residual bait and feces, the water discharged from the breeding pool 1 does not have to enter the biochemical pool after two-stage filtration. Half of the water enters the biochemical pool and the other half directly enters the decarbonation and aeration tower 33, thereby reducing the initial input of half of the biochemical pool and the conventional power consumption of the biochemical pool, and reducing the operating cost; of course, the water treatment device can also include a protein separator, which is used to remove suspended particles.

[0072] Specifically, the dehydration solidification device 28 is connected to a sewage pool 34, which is used to receive sewage precipitated from the dehydration solidification device 28. The sewage pool 34 is connected to a sewage pump 35, which is connected to the biological pool 31. The sewage in the sewage pool 34 is transported to the biological pool 31 for treatment through the sewage pump 35. The bottom of the biological pool 31 is connected to a sewage outlet pipe 36, which is connected to the dehydration solidification device 28. The sewage at the bottom of the biological pool 31 is transported to the dehydration solidification device 28 through the sewage outlet pipe 36 for solidification and storage;

[0073] Specifically, an ultraviolet sterilizer 37 is further provided between the decarbonization and oxygenation tower 33 and the water regulating tank 11 .

[0074] Specifically, an ammonia nitrogen and nitrite monitoring sensor 38 is further provided in the breeding pond 1 , and the ammonia nitrogen and nitrite monitoring sensor 38 is connected to the control module 12 , and the biological filter bed 32 is connected to the control module 12 .

[0075] Specifically, the control module 12 includes a data receiving unit 121, which is connected to a salinity sensor 13, a temperature sensor 14, a pH sensor 15, an oxygen content sensor 16, and an ammonia nitrogen and nitrite monitoring sensor 38. The data receiving unit 121 is connected to a data analysis and processing module 122, and the data analysis and processing module 122 is connected to a fresh water supply solenoid valve 19, a sea water supply solenoid valve 20, a water source heat pump 23, a heat exchanger 21, a first doser 25, a second doser 26, an aeration device 27, and a biological filter bed 32. The data analysis and processing module 122 is connected to a LoRa communication unit 123, and the LoRa communication unit 123 is connected to a LoRa gateway 124.

[0092] S1. Treat the seawater entering the aquaculture workshop for recycling, as follows:

[0093] S11, seawater tidal induction (introduction of new seawater);

[0094] S12, dark sedimentation of the introduced seawater for 48 hours;

[0095] S13, sand filtration;

[0096] S14, use 2-4PPM EDTA to complex heavy metals and adsorbent activated carbon to remove heavy metals from water;

[0097] S15, filtering through a 1200-mesh negative pressure rotary disc microfilter;

[0098] S16, ultraviolet disinfection;

[0099] In addition, when the aquaculture tail water is discharged from the workshop, it also needs to be filtered through a 1200-mesh negative pressure rotary disc microfilter;

[0100] S2. Circulation treatment of water used in the breeding workshop. The circulation process of the circulating water is as follows:

[0101] The dirt in the upper, middle and lower sections of the culture pond 1 flows to the circulating water ground pipe 4 through the segmented water sampler 3;

[0102] The residual bait and feces at the bottom of the culture pond 1 are discharged from the culture pond 1 through the directional sewage discharger 2, and the sewage flowing out through the directional sewage discharger 2 and the circulating water ground pipe 4 flows to the combined water tank 5, and flows into the filter 7 through the circulating water outlet pipe 6;

[0103] In the filter 7, the dirt and the circulating water are separated, and the purified circulating water flows to the water collection tank 9. The separated dirt enters the dehydration solidification device 28 for dehydration and solidification. The sewage separated by the dehydration solidification device 28 is injected into the sewage tank 34, and the water in the sewage tank 34 is transported to the biological tank 31.

[0104] The first water pump 29 delivers half of the circulating water in the water collection tank 9 to the biological pool 31. The water in the biological pool 31 is regularly delivered to the decarbonation and oxygenation tower 33. The sewage precipitated at the bottom of the biological pool 31 flows to the dehydration solidification device 28 through the sewage outlet pipe 36.

[0105] The second water pump 30 transports the remaining circulating water in the water collection tank 9 to the decarbonization and oxygenation tower 33. The circulating water after the decarbonization and oxygenation tower 33 is transported to the water regulating tank 11. The circulating water in the water regulating tank 11 is transported to each breeding pond 1 through the circulating water return pipe.

[0106] S3. Monitor the salinity in the culture pond 1 as follows:

[0107] The salinity sensor 13 monitors the salinity in the breeding pond 1 and transmits the salinity to the control module 12. The control module 12 has a preset salinity. For breeding hippocampus bulging, the preset salinity is maintained at 20-25‰, and for breeding hippocampus lineata, the preset salinity is maintained at 25-30‰. If the salinity in the breeding pond 1 is lower than the preset salinity, the control module 12 opens the seawater supply solenoid valve 20, and the high-salinity seawater stored in the second reservoir 18 flows into the water regulating tank 11, and seawater is added to the water regulating tank 11 to increase the salinity in the water regulating tank 11. If the salinity in the breeding pond 1 is higher than the preset salinity, the control module 12 opens the freshwater supply solenoid valve 19 to add fresh water to the water regulating tank 11; after adjusting the salinity in the water regulating tank 11, the circulating water flows to each breeding pond 1 through the circulating water return pipe to adjust the salinity in the breeding pond 1;

[0108] Changes in salinity during seahorse culture have an important impact on the health of seahorses, including feeding behavior, physiological and biochemical indicators, gene expression, growth and survival, etc. Therefore, during the culture process, the salinity in the culture pond 1 needs to be strictly controlled to ensure the healthy growth of seahorses.

[0109] S4, monitor the temperature in the culture pond 1, as follows:

[0110] The temperature sensor 14 monitors the temperature in the breeding pool 1 and transmits the temperature to the control module 12. The control module 12 has a preset temperature. The preset temperature for the hippocampus bulging is 16-19°C. The preset temperature for the hippocampus striata is 23-26°C. When the temperature in the breeding pool 1 is lower than the preset temperature, the control module 12 starts the heat exchanger 21 and the water source heat pump 23. The water in the third water reservoir 22 flows into the heat exchanger from the hot end inlet 211 and flows out from the hot end outlet 212 to the water source heat pump 23.

[0111] The water in the water collection tank 9 flows into the heat exchanger 21 from the cold end inlet 213 and flows out from the cold end outlet 214 to the water source heat pump 23; in the water source heat pump 23, the water discharged from the third water storage tank 22 and the water discharged from the water collection tank 9 are heat exchanged again; after the heat exchange, the water discharged from the third water storage tank 22 flows to the breeding pond 1;

[0112] Water temperature will affect growth and survival rate, reproductive capacity, feeding behavior and other aspects. By setting the temperature sensor 14, the optimal temperature for its growth can be accurately grasped, which can not only save time and cost, but also increase the unit output of seahorses, which is beneficial to improving the economic benefits of seahorse breeding. It can not only save time and cost, but also increase the unit output of seahorses.

[0113] S5. Monitor the pH value in the culture pond 1, as follows:

[0114] The pH sensor 15 monitors the pH value in the breeding pond 1 and transmits the pH value to the control module 12. The control module 12 has a preset pH value. In seahorse breeding, the optimal pH value is 7.8-8.5. If the pH value in the breeding pond 1 is lower than the preset pH value, the control module 12 controls the first doser 25 to add alkaline substances (such as carbonates) to the water adjustment tank 11; if the pH value in the breeding pond 1 is higher than the preset pH value, the control module 12 controls the second doser 26 to add acidic substances (such as carbon dioxide) to the water adjustment tank 11; after adjusting the pH value in the water adjustment tank 11, the circulating water flows to each breeding pond 1 through the circulating water return pipe to adjust the pH value in the breeding pond 1; for the amount of alkaline or acidic substances added, an intelligent algorithm (such as a PID control algorithm) is used to judge the difference between the current pH value and the target pH value, and the required adjustment amount is calculated. The control module 12 controls the first doser 25 or the second doser 26 to add alkaline or acidic substances to the water regulating pool 11 according to the adjustment amount; the pH value in the breeding pool 1 is maintained in a suitable range of 7.8-8.5, which can provide a stable and healthy growth environment for the seahorse. This not only helps to improve the survival rate and growth rate of the seahorse, but also reduces the need for manual monitoring and improves breeding efficiency.

[0115] S6. Monitor the oxygen content in the culture pond 1, as follows:

[0116] The oxygen content sensor 16 monitors the oxygen content in the culture pond 1 and transmits the oxygen content to the control module 12. The control module 12 has a preset oxygen content. If the oxygen content in the culture pond 1 is lower than the preset oxygen content, the control module 12 controls the aeration device 27 to start, so as to increase the oxygen content in the water regulating tank 11. After adjusting the oxygen content in the water regulating tank 11, the circulating water flows to each culture pond 1 through the circulating water return pipe to adjust the oxygen content in the culture pond 1.

[0117] S7. Monitor the concentrations of ammonia nitrogen and nitrite in the culture pond 1 as follows:

[0118] The ammonia nitrogen and nitrite monitoring sensor 38 detects the ammonia nitrogen and nitrite concentrations in the breeding pond 1, and transmits the ammonia nitrogen and nitrite concentrations to the control module 12. The control module 12 has preset ammonia nitrogen and nitrite concentrations. If the ammonia nitrogen and nitrite concentrations in the breeding pond 1 are higher than the preset ammonia nitrogen and nitrite concentrations, the control module 12 controls the water flow rate of the biological filter bed 32 to increase, and increases the aeration volume of the biological filter bed 32.

[0119] Specifically, it also includes the control of the LED lighting equipment in the breeding workshop. The light sensor 39 and the spectrum sensor 40 obtain the light intensity and spectrum data of the breeding workshop, and transmit the light intensity and spectrum data to the control module 12.

According to the preset light intensity and spectrum data, the control module 12 adjusts the light intensity and spectrum of the LED lighting equipment to make the light intensity and spectrum of the breeding workshop meet the preset light intensity and spectrum data.

[0120] The seahorse breeding workshop can be divided into several areas, each of which is equipped with LED lighting equipment, all of which are connected to the control module 12, and each area is equipped with a light sensor 39 and a spectrum sensor 40, the light sensor 39 is used to obtain the light intensity of the corresponding area, and the spectrum sensor 40 is used to obtain the spectrum in the seahorse breeding workshop. According to the preset target value, the PID algorithm calculates the adjustment amount, and according to the adjustment amount, the control module 12 controls the LED lighting equipment to make corresponding adjustments.

[0121] The breeding method also includes controlling the water flow rate in the breeding pond 1. The flow controller 41 adjusts the opening of its own valve according to the water flow rate in the circulating water return pipe, and the water flow rate in the circulating water return pipe of the flow controller 41 is fed back to the control module 12. The control module 12 adjusts the pumping power of the return pump 42 according to the preset water flow rate.

The method for intelligent and controllable cultivation of seahorses with circulating water according to claim 9, characterized in that: It also includes control of the LED lighting equipment in the breeding workshop. The light sensor and the spectrum sensor obtain the light intensity and spectrum data of the breeding workshop, and transmit the light intensity and spectrum data to the control module. The control module has preset light intensity and spectrum data. According to the preset light intensity and spectrum data, the control module adjusts the light intensity and spectrum of the LED lighting equipment so that the light intensity and spectrum of the breeding workshop meet the preset light intensity and spectrum data. The breeding method also includes controlling the water flow rate in the breeding pond. The flow controller adjusts the opening of its own valve according to the water flow rate in the circulating water return pipe, and the water flow rate in the circulating water return pipe of the flow controller is fed back to the control module. The control module adjusts the pumping power of the return pump according to the preset water flow rate.
