Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a water body circulation purification type hairy crab breeding pond. Background Art

[0002] The hairy crab breeding pond is a water facility specially used for breeding hairy crabs. Hairy crabs need a variety of nutrients to maintain their growth. In addition to natural bait, they also need to be regularly fed with various feeds, such as small fish, snails, blood meal and pupa powder. Water plants are the natural bait for hairy crabs and can also purify water quality. Planting water plants appropriately in the breeding pond and raising a certain number of snails can help provide rich bait and maintain stable water quality.

[0003] In combination with the above, it should be explained that traditional hairy crab breeding ponds need to replace and purify the water in the breeding ponds according to the breeding cycle. Affected by the replacement water reserves and purification project volume, as well as the lack of early prediction, timely analysis and intervention of hidden risks in the water, the water in the breeding ponds becomes diseased and abnormal before the breeding cycle, thus affecting the breeding and growth of hairy crabs. At the same time, the accuracy of water regulation in the breeding ponds is reduced, resulting in the hairy crabs in the breeding ponds being affected by the water, which leads to problems such as extended growth cycle, poor growth and development, and reduced survival rate. Summary of the invention

[0004] The purpose of the present invention is to provide a water body circulation and purification type hairy crab breeding pond, which collects follow-up data on the breeding of hairy crabs in separate breeding ponds, establishes a water body model according to an ARIMA model, and predicts advance data on water body circulation and purification in the separate breeding ponds for a period of time in the future according to the water body model, and obtains and analyzes internal dynamic parameter information and external interference parameter information accordingly, understands the hidden flow risk of the water body model during future operation, helps to provide early warning and operation data support for subsequent water body circulation and purification in the separate breeding ponds, reduces blind water circulation and purification in the separate breeding ponds, ensures the stable growth of hairy crabs in the separate breeding ponds, and solves the problems raised.

[0007] A water body monitoring platform is provided inside the control panel, and the water body monitoring platform records and stores real-time data collected from the initial stage to the current stage of the aquaculture pond;

[0008] The water body supervision platform is communicatively connected with a water area model unit, a flow assessment unit, a water change impact unit, a hidden danger feedback unit, a fusion assessment unit and an early warning processing unit;

[0009] The water area model unit stores the data of the use follow-up records from the beginning of the establishment of the aquaculture pond to the present simulation moment, and builds an online water body model based on the data in combination with the ARIMA model technology, and obtains internal dynamic parameter information and external interference parameter information according to the water body model, the internal dynamic parameter information includes the water oxygen assessment value and the water oxygen supervision value, and the external interference parameter information includes the water environment pollution value and the feeding risk value, and sends the internal dynamic parameter information and the external interference parameter information to the flow assessment unit and the water change impact unit respectively;

[0010] After receiving the internal dynamic parameter information, the flow assessment unit immediately performs implicit flow risk analysis on the internal dynamic parameter information and sends the obtained implicit flow risk coefficient YFi to the hidden danger feedback unit;

[0011] After receiving the external interference parameter information, the water change influencing unit immediately analyzes the external interference parameter information and sends the obtained purification and impurity removal signal to the early warning processing unit through the hidden danger feedback unit;

[0012] After receiving the implicit flow risk coefficient YFi, the hidden danger feedback unit immediately simulates the water purification value STJz with the data in the water body model, analyzes the water purification STJz value, and sends the obtained hidden danger risk coefficient YHFi to the fusion assessment unit;

[0013] After receiving the hidden danger risk coefficient YHFi, the fusion assessment unit immediately simulates the water body risk data with the data in the water body model. The water body risk data includes hydration characteristic values ​​and hydration performance values. Based on this, the water body risk data is analyzed and the obtained management and control signals and regulation signals are sent to the early warning processing unit.

[0014] Furthermore, the specific operation process of the flow evaluation unit is as follows:

[0015] The duration between the start and end of the simulation of the water body model is collected and marked as the time threshold, and the water oxygen assessment value and water oxygen supervision value of the water body model simulated according to the data within the time threshold are obtained. The water oxygen assessment value is expressed as the interval value obtained by scaling the data between the maximum water oxygen content range value and the duration corresponding to the maximum water oxygen content range value during the high-volume crab farming period in the water body model. The water oxygen supervision value is expressed as the ratio of the number of times the water oxygen content is less than the maximum water oxygen content range value and the average interval duration corresponding to the number of times the water oxygen content is less than the maximum water oxygen content range in the time between the injection of data and the current time of the water body model, and the water oxygen assessment value and water oxygen supervision value are marked as SYPz and SYJz, respectively, and the implicit flow risk coefficient YFi is obtained according to the formula.

[0016] Furthermore, the specific operation process of the water change influencing unit is as follows:

[0017] The water environment pollution value simulated by the water body model according to the data within the time threshold is obtained. The water environment pollution value indicates the value of the simulated water body environmental parameter exceeding the preset threshold, and then the part of the numerical value corresponding to the environmental parameter exceeding the preset threshold is processed by interval scaling of the data to obtain an interval value. The water environment pollution value includes the harmful impurity proportion value and the water temperature risk value. The harmful impurity proportion value indicates the interval value obtained by the interval scaling of the time corresponding to the line segment of the harmful impurity proportion characteristic curve located above the preset harmful impurity proportion characteristic curve and the average proportion of nutrient substances. The water temperature risk value is expressed as the interval value obtained by the interval scaling of the part of the water body suitable temperature range value exceeding the preset water body set temperature range value and the water surface temperature range value.

[0018] Further, the feeding risk value of the water body model within the time threshold is obtained according to the data simulation, and the feeding risk value represents the interval value obtained by the interval scaling of the timed crab feed feeding range value and the timed crab consumption range value, and then the interval value obtained by the interval scaling of the data with the feed loss range value, and the feed loss range value is represented by the interval value obtained by the interval scaling of the data from the feed feeding time range value to the feed consumption time range value of the farmed crab;

The water body purification value represents the interval value obtained by scaling the number of purification times and the number of purification degree ranges of the water body in the aquaculture pond in the water body model parameters. The purification degree is expressed as the value range of the single purified water body in the total water body. The water body environmental pollution value, feeding risk value and water body purification value are marked as STWz, TWFz and STJz respectively, and the hidden danger risk coefficient YHFi is obtained according to the formula.

[0022] Furthermore, the specific process of water body risk assessment analysis of the fusion assessment unit is as follows;

[0023] The hydration characteristic value of the water body model simulated according to the data within the time threshold is obtained. The hydration characteristic value indicates the value of the water body parameter corresponding to the value exceeding the preset threshold. The water body parameter includes the pH range and the crab metabolism range value. The hydration characteristic value is compared and analyzed with the preset hydration characteristic value threshold stored in the record. If the hydration characteristic value is greater than the preset hydration characteristic value threshold, the part of the hydration characteristic value greater than the preset hydration characteristic value threshold is marked as the growth risk value SZFz;

[0024] The hydration performance value simulated by the water body module according to the data within the time threshold is obtained. The hydration performance value indicates the value of the water parameter corresponding to the value exceeding the preset threshold. The hydration parameter includes the plankton range value and the aquatic organism range value. The hydration performance value is compared and analyzed with the preset hydration performance value threshold stored in the record. If the hydration performance value is greater than the preset hydration performance value threshold, the part of the hydration performance value greater than the preset hydration performance value threshold is marked as the growth impact value SZYz;

[0025] The water body risk assessment coefficient STPGi is obtained according to the formula, and the water body risk assessment coefficient STPGi is compared and analyzed with the preset water body risk assessment coefficient YTPGi threshold stored in the record; if the ratio between the water body risk assessment coefficient STPGi and the preset water body risk assessment coefficient YTPGi threshold is greater than or equal to 1, a control signal is generated; if the ratio between the water body risk assessment coefficient STPGi and the preset water body risk assessment coefficient YTPGi threshold is less than 1, a feedback instruction is generated.

[0026] Further, when the fusion evaluation unit generates a feedback instruction;

A rectangular coordinate system is established with the number of water body risk assessment coefficients STPGi as the X-axis and the water body risk assessment coefficients STPGi as the Y-axis. The water body risk assessment coefficient STPGi curve is drawn by drawing points, and the ratio of the total length corresponding to the rising line segment to the total length corresponding to the falling line segment in the water body risk assessment coefficient STPGi curve is obtained. The ratio is marked as the water cycle trend risk coefficient, and the water cycle trend risk coefficient is compared and analyzed with the preset water cycle trend risk coefficient threshold value stored in the record; if the water cycle risk trend coefficient is less than the preset water cycle risk trend coefficient threshold, no signal is generated; if the water cycle risk trend coefficient is greater than or equal to the preset water cycle risk trend coefficient threshold, an alarm control signal is generated.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 4 As shown, this embodiment is a water circulation purification type hairy crab breeding pond, comprising a breeding pond 1, a plurality of breeding ponds 2 and a water purification component 5 are arranged on the top of the breeding pond 1, a sunbathing beach 201 is arranged on the top of the sunbathing beach 201, a gentle slope 202 is arranged inside the sunbathing beach 201, and a slag collecting trough 203 is arranged at the bottom of the gentle slope 202;

[0040] The center of the bottom of the sub-cultivation pond 2 is provided with an arc bottom 204, and the middle part of the arc bottom 204 is convex upward longitudinally, so that the feeding food residue in the sub-cultivation pond 2 is accumulated along the arc bottom 204 landform and the water flow guiding value slag collecting trough 203 area. An isolation cover 205 is provided in the bottom pool wall of the sub-cultivation pond 2. During the daily feeding of hairy crabs, a certain amount of hairy crab seedlings are put in according to the area of ​​the sub-cultivation pond 2. The sub-cultivation pond 2 is covered and protected by the isolation cover 205 to prevent the hairy crabs from digging holes and escaping. The hairy crabs are provided with daily activities in the water or on the ground through the gentle slope 202 and the sun-drying beach 201, and the sun-drying beach 201 is used to ensure the sun exposure required for the growth of the hairy crabs.

[0041] A water pumping trough 3 is provided at the bottom of the culture tank 2, which is located between the slag collecting trough 203 and the arc bottom 204. A plurality of water spray valves 4 are provided at the top of the arc bottom 204. A top filter element 501 is provided at the top of the water purification component 5. A control box 502 is provided on the outer wall of the top filter element 501, and a control panel is provided inside the control box 502. A circulating water pump is provided at the bottom of the top filter element 501.

[0042] A pumping pipe 503 connected to the pumping trough 3 is provided on the top valve port of the circulating water pump, and a water delivery pipe 504 connected to the spray valve 4 is provided on the bottom valve port of the circulating water pump. When the circulating water pump draws water from the sub-cultivation pond 2 along the pumping trough 3 through the pumping pipe 503, the residue accumulated in the slag collecting trough 203 is sucked and cleaned together, and filtered and purified by the top filter element 501, and then injected into the adjacent sub-cultivation pond 2 that needs water injection, the extracted sub-cultivation pond 2 is guided into high-quality water in other adjacent sub-cultivation ponds 2, and the guided high-quality water is transported to the spray valve 4 by the circulating water pump through the pumping pipe 503, and sprayed from the water surface of the sub-cultivation pond 2, so as to realize the bottom-pumping and top-injection circulation structure, and constitute the purification treatment of the water in the extracted sub-cultivation pond 2, while avoiding excessive changes in the water quality and water flow in the sub-cultivation pond 2, which would cause excessive changes in the living environment of the hairy crabs raised in the sub-cultivation pond 2.

[0043] Example 2: Please refer to Figure 1-Figure 5 As shown, this embodiment is used to solve the problem that the water in the traditional hairy crab breeding ponds needs to be replaced and purified according to the breeding cycle, which is affected by the replacement water storage and purification engineering volume, as well as the lack of early prediction, timely analysis and intervention of hidden risks in the water, causing the water in the breeding ponds to become diseased and abnormal before the breeding cycle, thereby affecting the breeding and growth of hairy crabs.

[0044] This embodiment is a water circulation purification type hairy crab breeding pond, wherein a water body supervision platform is arranged inside the control panel, and the water body supervision platform is communicatively connected with a water area model unit, a flow assessment unit, a water change impact unit, a hidden danger feedback unit, a fusion assessment unit and an early warning processing unit; the water body supervision platform records and stores the real-time data collected from the initial stage to the current stage of the breeding pond;

[0045] The water area model unit stores the data of the use follow-up records from the establishment of the aquaculture pond to the current simulation moment, and builds an online water body model based on this data in combination with the ARIMA model technology, and obtains internal dynamic parameter information and external interference parameter information based on the water body model. The internal dynamic parameter information includes water oxygen assessment value and water oxygen supervision value, and the external interference parameter information includes water environment pollution value and feeding risk value. The internal dynamic parameter information and external interference parameter information are sent to the flow assessment unit and the water change impact unit respectively;

[0046] By collecting follow-up data on the breeding of hairy crabs in the sub-breeding pond 2, and establishing a water model based on the ARIMA model, and predicting the water circulation and purification of the sub-breeding pond 2 in the future based on the water model, and obtaining and analyzing the internal dynamic parameter information and external interference parameter information, we can understand the hidden flow risks of the water model during the future operation, which will help to provide early warning and operation data support for the subsequent water circulation and purification of the sub-breeding pond 2, reduce the blind water circulation and purification of the sub-breeding pond 2, and ensure the stable growth of the hairy crabs in the sub-breeding pond 2. The specific operation process of the flow assessment unit is as follows:

[0047] The duration between the start and end of the simulation of the water body model is collected and marked as a time threshold, and the water oxygen assessment value and water oxygen supervision value of the water body model simulated according to the data within the time threshold are obtained. The water oxygen assessment value is expressed as the interval value obtained by scaling the data between the maximum water oxygen content range value and the duration corresponding to the maximum water oxygen content range value during the high-volume crab farming period in the water body model. The water oxygen supervision value is expressed as the ratio of the number of times the water oxygen content is less than the maximum water oxygen content range value and the number of times the water oxygen content is less than the maximum water oxygen content range in the time between the injection of data and the current time of the water body model. The water oxygen assessment value and the water oxygen supervision value are marked as SYPz and SYJz, respectively. It should be noted that the high-volume crab farming is expressed as the simulated farming quantity of hairy crabs within the time threshold;

[0048] According to the formula The implicit flow risk coefficient is obtained, where q1 and q2 are the preset proportional factor coefficients of the water and oxygen assessment value and the water and oxygen supervision value respectively. The proportional factor coefficients are used to correct the deviations of various parameters in the formula calculation process, so as to make the calculation results more accurate. q1 and q2 are both positive numbers greater than zero. q3 is the preset correction factor coefficient with a value of 1.788. YFi is the implicit flow risk coefficient, and the implicit flow risk coefficient YFi is sent to the hidden danger feedback unit. The size of the coefficient is to quantify each parameter to obtain a specific value, which is convenient for subsequent comparison. The size of the coefficient depends on the amount of sample data and the preliminary setting of the corresponding coefficient for each group of sample data by technical personnel in this field, as long as it does not affect the proportional relationship between the parameter and the quantified value.

[0049] After receiving the external interference parameter information, the water change influencing unit immediately analyzes the external interference parameter information and sends the obtained purification and impurity removal signal to the early warning processing unit through the hidden danger feedback unit. The specific operation process of the water change influencing unit is as follows:

[0050] The water environment pollution value simulated by the water body model according to the data within the time threshold is obtained. The water environment pollution value indicates the value of the simulated water environment parameter exceeding the preset threshold, and then the part of the value corresponding to the environmental parameter exceeding the preset threshold is processed by interval scaling of the data to obtain an interval value. The water environment pollution value includes a harmful impurity ratio value and a water temperature risk value. The harmful impurity ratio value indicates the interval value obtained by the interval scaling of the time corresponding to the line segment of the harmful impurity ratio characteristic curve located above the preset harmful impurity ratio characteristic curve and the average nutrient material ratio. The water temperature risk value is expressed as the interval value obtained by the interval scaling of the part of the water body suitable temperature range value exceeding the preset water body set temperature range value and the water surface temperature range value. It should be noted that the larger the value of the water environment pollution value, the greater the interference and risk to the water circulation and purification in the overall sub-cultivation pond 2;

[0051] The feeding risk value of the water body model within the time threshold is obtained according to the data simulation. The feeding risk value represents the interval value obtained by the interval scaling of the timed crab feed feeding range value and the timed crab consumption range value, and then the interval value obtained by the interval scaling of the data with the feed loss range value. The feed loss range value is represented by the interval value obtained by the interval scaling of the feed feeding time range value to the feed feeding time range value of the crab breeding time. It should be noted that the larger the value of the feeding risk value, the easier it is to cause the water body to be rich and the residue to be deposited in the sub-breeding pond 2, resulting in a higher risk of water body abnormality in the sub-breeding pond 2;

[0052] Compare and analyze the water environment pollution value and feeding risk value with the preset water environment pollution value and preset feeding risk value thresholds stored in the record;

[0053] If the water body environmental pollution value is less than the preset water body environmental pollution value threshold, and the feeding risk value is less than the preset feeding risk value threshold, no signal is generated;

[0054] If the water environment pollution value is greater than or equal to the preset water environment pollution value threshold, and the feeding risk value is greater than or equal to the preset feeding risk value threshold, a purification and impurity removal signal is generated and sent to the early warning processing unit. After receiving the purification and impurity removal signal, the early warning processing unit immediately controls the water circulation equipment and water purifier of the sub-breeding pond 2 to quickly process the water in the sub-breeding pond 2 to avoid affecting the growth of the hairy crabs.

[0055] Example 3: Please refer to Figure 1-Figure 5 As shown, this embodiment is used to solve the problem of reducing the control accuracy of the water body in the separate breeding pond, resulting in the influence of the water body on the hairy crabs in the separate breeding pond, which leads to the extension of the growth cycle of the hairy crabs, poor growth and development, and reduced survival rate.

[0056] This embodiment is a water circulation purification type hairy crab breeding pond, including a hidden danger feedback unit that, upon receiving the implicit flow risk coefficient YFi, immediately simulates the water purification value STJz with the data in the water model, analyzes the water purification STJz value, and sends the obtained hidden danger risk coefficient YHFi to the fusion evaluation unit. The specific operation process of the hidden danger feedback unit is as follows:

[0057] Obtain the implicit flow risk coefficient YFi of the water model within the time threshold, retrieve the water environment pollution value and feeding risk value from the water change impact unit, and obtain the water purification value of the water model within the time threshold. The water purification value represents the interval value obtained by scaling the number of purification times and the number of purification degree ranges of the water body in the aquaculture pond in the water model parameters. The purification degree is expressed as the value range of the single purified water body in the total water body, and the water environment pollution value, feeding risk value and water purification value are marked as STWz, TWFz and STJz respectively;

[0058] According to the formula Obtain the hidden danger risk coefficient, where w1, w2, w3 and w4 are preset weight factor coefficients of hidden flow risk coefficient, water environment pollution value, feeding risk value and water purification value respectively, w1, w2, w3 and w4 are all positive numbers greater than zero, w5 is the preset fault tolerance factor coefficient, the value is 2.156, YHFi is the hidden danger risk coefficient, and the hidden danger risk coefficient YHFi is sent to the fusion evaluation unit;

[0059] After receiving the hidden danger risk coefficient YHFi, the fusion assessment unit immediately simulates the water body risk data with the data in the water body model. The water body risk data includes hydration characteristic values ​​and hydration performance values. Based on this, the water body risk data is analyzed and the obtained control signal and regulation signal are sent to the early warning processing unit. The specific process of the water body risk assessment analysis of the fusion assessment unit is as follows;

[0060] The hydration characteristic value of the water body model simulated according to the data within the time threshold is obtained. The hydration characteristic value indicates that the value corresponding to the water body parameter exceeds the value of the preset threshold. The water body parameter includes the pH range and the crab metabolism range value. The hydration characteristic value is compared and analyzed with the preset hydration characteristic value threshold stored in the record. If the hydration characteristic value is greater than the preset hydration characteristic value threshold, the part of the hydration characteristic value greater than the preset hydration characteristic value threshold is marked as the growth risk value SZFz. It should be noted that the larger the value of the growth risk value SZFz is, the greater the impact of the water in the sub-cultivation pond 2 on the growth of the hairy crab is.

[0061] The hydration performance value of the water body module simulated according to the data within the time threshold is obtained. The hydration performance value indicates that the value corresponding to the parameter in the water exceeds the value of the preset threshold. The hydration parameter includes a plankton range value and a water organism range value. The hydration performance value is compared and analyzed with the preset hydration performance value threshold stored in the record. If the hydration performance value is greater than the preset hydration performance value threshold, the part of the hydration performance value greater than the preset hydration performance value threshold is marked as the growth impact value SZYz. It should be noted that the larger the value of the growth impact value SZYz is, the easier it is to interfere with the normal growth cycle of the hairy crab in the sub-cultivation pond 2;

[0062] According to the formula The water body risk assessment coefficient STPGi is obtained, wherein e1, e2 and e3 are respectively the preset influencing factor coefficients of the growth risk value, the growth impact value and the hidden danger risk coefficient, e4 is the compensation factor coefficient, e1, e2, e3 and e4 are all positive numbers greater than zero, G is the water body risk assessment coefficient, and the water body risk assessment coefficient STPGi is compared and analyzed with the preset water body risk assessment coefficient YTPGi threshold value stored in the record;

[0063] If the ratio between the water body risk assessment coefficient STPGi and the preset water body risk assessment coefficient YTPGi threshold is greater than or equal to 1, a control signal is generated, and the control signal is sent to the early warning processing unit. After receiving the control signal, the early warning processing unit immediately displays the preset processing scheme corresponding to the control signal on the display screen of the main control room, and controls the water circulation and purification of the sub-breeding pond 2 corresponding to the control signal, so as to improve the reasonable control of the water in the sub-breeding pond 2;

[0064] If the ratio between the water body risk assessment coefficient STPGi and the preset water body risk assessment coefficient YTPGi threshold is less than 1, a feedback instruction is generated. When the feedback instruction is generated, the water body risk assessment coefficient STPGi corresponding to the feedback signal is obtained, and the water body risk assessment coefficient STPGi corresponding to the n feedback signals before this moment is obtained synchronously based on the data simulation of the water body model, where n is a natural number greater than zero. A rectangular coordinate system is established with the number of water body risk assessment coefficients STPGi as the X-axis and the water body risk assessment coefficient STPGi as the Y-axis. The water body risk assessment coefficient STPGi curve is drawn by drawing points, and the ratio of the total length corresponding to the rising line segment to the total length corresponding to the falling line segment in the water body risk assessment coefficient STPGi curve is obtained, and it is marked as a water cycle trend risk coefficient, and the water cycle trend risk coefficient is compared and analyzed with the preset water cycle trend risk coefficient threshold recorded and stored;

[0065] If the water cycle risk trend coefficient is less than the preset water cycle risk trend coefficient threshold, no signal is generated;

[0066] If the water cycle risk trend coefficient is greater than or equal to the preset water cycle risk trend coefficient threshold, an alarm control signal is generated and the control signal is sent to the early warning processing unit.
