Description

Technical Field

[0001] The invention relates to the technical field of aquaculture anchoring, and in particular to a management method and system for a lifting type cage anchoring device. Background Art

[0002] Liftable cage mooring devices are widely used in the aquaculture industry. Due to their flexible structure and good adaptability, they can effectively cope with different water environments. However, most existing management technologies focus on monitoring a single environmental parameter, such as water level or water quality indicators, and lack real-time monitoring and evaluation of comprehensive environmental factors. This single monitoring method makes it difficult for aquaculture managers to fully understand the changes in the environment in which the cage is located, and they are unable to respond to fluctuations in external conditions in a timely manner, resulting in the anchoring stability of the device being affected, which may cause displacement or drifting, and even cause significant economic losses. In addition, existing technologies often have problems with information lag and untimely response when the environment changes rapidly, which poses a threat to the survival of farmed organisms.

[0003] In addition, many traditional monitoring methods rely on manual inspections and regular sampling, which not only consumes manpower and material resources, but is also easily interfered by human factors. The judgment of water quality health also often relies on a single or limited parameter, such as pH or turbidity, and fails to comprehensively consider the potential impact of flow rate, wind speed, etc. on the water ecology. This one-sided monitoring method leads to managers' lack of comprehensiveness in formulating strategies, making it difficult to accurately assess environmental conditions, which may result in missing the best management opportunities and response measures. The limitations of existing technologies in dealing with environmental and water quality changes have seriously restricted the effective management of lifting cage mooring devices and the sustainable development of aquaculture. Therefore, a more systematic and comprehensive management method is urgently needed to overcome the shortcomings of these existing technologies.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0005] The object of the present invention is to provide a method and system for managing a lifting cage anchoring device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A method and system for managing a lifting cage anchoring device, the specific steps comprising:

[0008] Step 1: collecting the environmental parameters and GPS position of the lifting cage anchoring device in real time, and calculating the displacement data of the device through the GPS position, wherein the environmental parameters are water level, water flow velocity, wind speed, temperature, pH value and water turbidity;

[0012] Furthermore, the water level height H and water flow velocity V are collected in real time by sensors. f , wind speed v w , temperature T and water pH;

[0013] The collected water level height is the water level height at the location of the lifting cage anchoring device, that is, the vertical distance from the bottom of the water body to the water surface; the collected water level height is compared with the preset water level height assessment threshold. If it exceeds the threshold range, the difference between the current water level height and the preset threshold is calculated and recorded as ΔH; if it does not exceed the threshold range, it will not be included in the subsequent calculation of the comprehensive environmental index;

[0014] The collected water pH value is compared with the preset pH assessment threshold. If it exceeds the threshold range, the difference between the current water pH value and the preset threshold is calculated and recorded as ΔP; if it does not exceed the threshold range, it will not be included in the subsequent calculation of water quality health indicators;

[0015] The specific logic for collecting water turbidity is: collect a certain volume of water to be tested as a sample and place it in a cool place. Before measuring, calibrate it with a known turbidity standard solution to ensure accurate measurement, and use the following formula to calculate the water turbidity:

[0016]

[0017] Among them, TUR is the turbidity of water, I is the measured light intensity, that is, the light intensity received by the sensor after passing through the water sample, and I0 is the incident light intensity, that is, the light intensity that has not passed through the water sample.

[0018] Furthermore, the displacement data calculated by the GPS position calculation device is based on the following specific logic:

[0019] Record the GPS coordinates of the device at time t1 and time t2 (lat1, long1), (lat2, long2);

[0020] Convert longitude and latitude to plane coordinates:

[0021] x1=long1×cos(lat1)×111.32, y1=lat1×111.32

[0022] x2=long2×cos(lat2)×111.32, y2=lat2×111.32

[0027] Furthermore, the formula for generating the comprehensive environmental index is as follows:

[0033] Further, the formula for generating the water quality health index is as follows:

[0034]

[0035] Among them, HEA is the water quality health index, ΔP is the difference between the current water body pH value and the preset threshold, TUR is the water body turbidity, and C3 is the third constant correction index.

[0036] Further, the formula for generating the comprehensive evaluation index for reflecting the overall state of the system is as follows:

[0037]

[0038] Among them, QS is the comprehensive evaluation index, ENV is the comprehensive environment index, ω1 is its preset proportional coefficient, STA is the mooring stability index, ω2 is its preset proportional coefficient, HEA is the water quality health index, ω3 is its preset proportional coefficient, and ω2>ω3>ω1>0, C4 is the fourth constant correction index.

[0039] Further, the specific logic for comparing the comprehensive evaluation index with the preset evaluation threshold is as follows:

[0040] Compare the comprehensive evaluation index QS with the preset evaluation threshold QY, and formulate corresponding management strategies according to the comparison results:

[0041] When QS ≤ 0.5QY, it is judged that the current environmental conditions are poor. If it is ascending or descending, reduce the ascending and descending speed to prevent further equipment damage; at the same time, set the water quality evaluation threshold, compare the water quality health index with the water quality evaluation threshold, and if the water quality health index exceeds the water quality evaluation threshold, immediately start the water quality purification and regulation measures, then immediately start the water quality purification and regulation measures;

[0042] When 0.5QY < QS ≤ QY, it is judged that the current environmental conditions are average. Adjust the ascending and descending speed according to the flow rate and water level changes to ensure safety, and regularly check the water quality to ensure that the pH value and turbidity meet the standards;

[0043] When QS > QY, it is judged that the current environmental conditions are safe, and the mooring position and ascending and descending state can be continued to be maintained, and regular maintenance and inspection of the device are carried out to ensure that the device is in good condition;

[0044] Among them, QS is the comprehensive evaluation index, and QY is the evaluation threshold.

[0045] The present invention also further provides a management system for a lifting cage mooring device. The management system for a lifting cage mooring device is used to execute the above-mentioned management method for a lifting cage mooring device, including:

[0046] A parameter acquisition module is used to collect the environmental parameters and GPS position of the lifting cage anchoring device in real time, and calculate the displacement data of the device through the GPS position, wherein the environmental parameters are water level, water flow velocity, wind speed, temperature, pH value and water turbidity;

[0056] Example:

[0057] See also Figure 1 , the present invention provides a technical solution:

[0058] A method for managing a lifting cage anchoring device, the specific steps comprising:

[0059] Step 1: collecting the environmental parameters and GPS position of the lifting cage anchoring device in real time, and calculating the displacement data of the device through the GPS position, wherein the environmental parameters are water level, water flow velocity, wind speed, temperature, pH value and water turbidity;

[0060] In this embodiment, the water level height H and water flow velocity V are collected in real time by sensors. f , wind speed V w , temperature T and water pH;

[0061] The collected water level height is the water level height at the location of the lifting cage anchoring device, that is, the vertical distance from the bottom of the water body to the water surface; the collected water level height is compared with the preset water level height assessment threshold. If it exceeds the threshold range, the difference between the current water level height and the preset threshold is calculated and recorded as ΔH; if it does not exceed the threshold range, it will not be included in the subsequent calculation of the comprehensive environmental index;

[0062] The collected water pH value is compared with the preset pH assessment threshold. If it exceeds the threshold range, the difference between the current water pH value and the preset threshold is calculated and recorded as ΔP; if it does not exceed the threshold range, it will not be included in the subsequent calculation of water quality health indicators;

[0063] The specific logic for collecting water turbidity is: collect a certain volume of water to be tested as a sample and place it in a cool place. Before measuring, calibrate it with a known turbidity standard solution to ensure accurate measurement, and use the following formula to calculate the water turbidity:

[0064]

[0065] Among them, TUR is the turbidity of water, I is the measured light intensity, that is, the light intensity received by the sensor after passing through the water sample, and I0 is the incident light intensity, that is, the light intensity that has not passed through the water sample.

[0066] The displacement data of the GPS location calculation device is based on the following specific logic:

[0067] Record the GPS coordinates of the device at time t1 and time t2 (lat1, long1), (lat2, long2);

[0068] Convert longitude and latitude to plane coordinates:

[0069] x1=long1×cos(lat1)×111.32, y1=lat1×111.32

[0070] x2=long2×cos(lat2)×111.32, y2=lat2×111.32

[0071] Among them, (x1, y1) and (x2, y2) are the position data after conversion into plane coordinates;

[0072] Calculate the distance between two points using the Euclidean distance formula:

[0073]

[0074] Wherein, d is the displacement of the device between time t1 and time t2, (x1, y1) and (x2, y2) are the position data after conversion into plane coordinates.

[0075] Step 1 can comprehensively and real-time monitor multiple key factors by collecting environmental parameters and GPS positions of the lifting cage mooring device in real time. This multi-parameter monitoring method provides a complete view of changes in the water environment, surpassing the limitations of single or limited parameter monitoring in traditional technologies. In addition, the displacement of the device can be calculated through GPS position data, and the movement of the mooring device can be identified in time, providing instant feedback to managers.

[0076] Step 1 lays the foundation for the subsequent dimensionless processing and comprehensive evaluation. By obtaining comprehensive and real-time environmental data, the subsequent steps can more accurately generate comprehensive environmental indexes, anchor stability indicators, and water quality health indicators. The accuracy and reliability of such indicators directly affect the formulation of comprehensive evaluation indexes, thereby ensuring the effectiveness of management strategies. This step plays a key supporting and promoting role in the overall plan, ensuring the scientificity and operability of the plan.

[0077] Step 2: Generate a comprehensive environmental index based on the dimensionless processed water level, water flow velocity, wind speed and temperature data; generate an anchor stability index based on the dimensionless processed flow velocity, wind speed and displacement data of the lifting device; generate a water quality health index based on the dimensionless processed pH value and water turbidity data;

[0078] In this embodiment, the formula for generating the comprehensive environmental index is as follows:

[0079]

[0080] Among them, ENV is the comprehensive environmental index, V f is the water flow rate, α is its preset proportional coefficient, ΔH is the difference between the water level and the preset threshold, β is its preset proportional coefficient, V w is wind speed, T is temperature, γ is The preset proportional coefficient, and α>β>γ>0, is because the water level and flow rate will directly affect the physical stability of the mooring device, and have a significant impact on the floating device, and the water level change will directly affect the immersion depth and stability of the device; temperature affects aquatic ecology and water quality, but the direct impact on the mooring device is relatively small, and it is mainly used for ecological monitoring. C1 is the first constant correction index; when the water flow rate is faster, it is helpful for the self-purification of the water body and reduces the concentration of pollutants. Therefore, when the water flow rate increases, the comprehensive environmental index ENV increases; too high water level will increase the risk of floods, and too low water level may cause drought, affecting water quality and biological survival. Therefore, when the difference ΔH between the water level and the preset threshold increases, the comprehensive environmental index ENV decreases; higher wind speeds will increase the evaporation rate of the water surface, and at the same time affect the mixing degree of the water body, thereby affecting the water temperature and dissolved oxygen content. Therefore, when the wind speed increases, the comprehensive environmental index ENV decreases; when the temperature rises, it will reduce the dissolved oxygen content in the water, affecting the water quality, and the comprehensive environmental index ENV decreases; that is, V f It is positively correlated with the comprehensive environmental index ENV, ΔH, V w , T is negatively correlated with the comprehensive environmental index ENV.

[0081] The formula for generating the anchor stability index is as follows:

[0082]

[0083] Among them, STA is the anchor stability index, V w is the wind speed, V f is the water velocity, d is the displacement of the device, μ is the preset proportional coefficient, and μ is greater than zero, and C2 is the second constant correction index; when the water velocity increases, the hydrodynamic load will increase, and the force applied to the mooring device will also increase, making the mooring stability worse and the mooring stability index STA increase; high wind speed will cause waves to increase, and the combination of strong wind and waves will cause greater disturbances on the water surface, resulting in displacement and tilt of the mooring device. Therefore, when the wind speed increases, the mooring stability deteriorates and the mooring stability index STA increases; when the device displacement increases, the mooring stability deteriorates and the mooring stability index STA increases; that is, V w 、V f , d are positively correlated with the anchoring stability index STA.

[0084] The formula for generating the water quality health index is as follows:

[0085]

[0086] Among them, HEA is the water quality health index, ΔP is the difference between the current water pH value and the preset threshold, TUR is the water turbidity, and C3 is the third constant correction index; when the difference between the water pH value and the preset threshold increases, it will affect the solubility of nutrients in the water, and deviation from the normal pH range may cause biological growth slowdown, reproduction problems or even death. Therefore, when ΔP increases, the water quality deteriorates and the water quality health index HEA increases; water with high turbidity will reduce the transmittance of light and affect the photosynthesis of aquatic plants. Therefore, when the water turbidity TUR increases, the water quality deteriorates and the water quality health index HEA increases; that is, ΔP, TUR and the water quality health index HEA are positively correlated.

[0087] Step 3: Combine the comprehensive environmental index, anchor stability index and water quality health index, conduct correlation analysis, and generate a comprehensive evaluation index to reflect the overall status of the system;

[0088] In this embodiment, the formula for generating the comprehensive evaluation index for reflecting the overall status of the system is as follows:

[0089]

[0090] Among them, QS is the comprehensive evaluation index, ENV is the comprehensive environment index, ω1 is its preset proportional coefficient, STA is the mooring stability index, ω2 is its preset proportional coefficient, HEA is the water quality health index, ω3 is its preset proportional coefficient, and ω2 > ω3 > ω1 > 0. This is because the mooring stability is directly related to the safety and functionality of the device. If the mooring is unstable, it may cause the device to drift or be damaged. Therefore, it usually occupies a higher weight in management; the water quality health affects the overall health of aquatic organisms and ecosystems. Especially in devices related to aquaculture and ecological protection, this index considers various environmental factors and has a wide impact on the health of the overall ecosystem and the operating environment of the mooring device; although the comprehensive environment index is important, in specific operations, its specific impact is relatively indirect; C4 is the fourth constant correction index; when the comprehensive environment index ENV increases, it indicates that the environmental conditions where the device is located are better, so the comprehensive evaluation index QS increases; when the mooring stability index STA increases, it indicates that the mooring stability weakens, so the comprehensive evaluation index QS decreases; when the water quality health index increases, it indicates that the water quality of the water body where the device is located deteriorates, so the comprehensive evaluation index QS decreases; that is to say, ENV and QS are positively correlated, and STA and HEA are negatively correlated with QS.

[0091] Step 4: Compare the comprehensive evaluation index with the preset evaluation threshold, and formulate corresponding management strategies according to the comparison results;

[0092] In this embodiment, the specific logic based on which the comprehensive evaluation index is compared with the preset evaluation threshold is as follows:

[0093] Compare the comprehensive evaluation index QS with the preset evaluation threshold QY, and formulate corresponding management strategies according to the comparison results:

[0094] When QS ≤ 0.5QY, it is judged that the current environmental conditions are poor. If it is in the process of lifting or lowering, reduce the lifting or lowering speed to prevent further equipment damage; at the same time, set the water quality evaluation threshold, compare the water quality health index with the water quality evaluation threshold. If the water quality health index exceeds the water quality evaluation threshold, immediately start the water quality purification and regulation measures, then immediately start the water quality purification and regulation measures;

[0095] When 0.5QY < QS ≤ QY, it is judged that the current environmental conditions are average. Adjust the lifting or lowering speed according to the flow velocity and water level changes to ensure safety, and regularly check the water quality to ensure that the pH value and turbidity meet the standards;

[0096] When QS > QY, it is judged that the current environmental conditions are safe. The mooring position and the lifting or lowering state can be continuously maintained, and regular maintenance and inspection of the device can be carried out to ensure that the device remains in good condition;

[0097] Among them, QS is the comprehensive evaluation index and QY is the evaluation threshold.

[0098] Step 4 can quickly and intuitively determine the overall state of the environment in which the device is located by comparing the comprehensive evaluation index with the preset evaluation threshold. This method enables managers to clearly identify when action is needed and what specific measures should be taken, thereby achieving precise management. Compared with traditional methods, this step not only improves the scientific nature of decision-making, but also significantly shortens the response time. Existing monitoring systems often rely on manual judgment or experience-based decisions, lack of systematic and standardized management basis, and increase the randomness and uncertainty of decision-making. Step 4 provides a clear action guide through data-based threshold comparison, reducing the interference of human factors. This quantitative management strategy can effectively reduce risks, optimize resource allocation, and improve management efficiency.

[0099] Step 4 provides decision support for the entire program, allowing the previously obtained comprehensive evaluation index to be transformed into actual management actions. By formulating corresponding management strategies in a timely manner, managers can implement preventive or corrective measures according to environmental changes to ensure the stability of cage anchoring devices and the health of farmed organisms. This mechanism plays a core role in ensuring aquaculture safety, improving economic benefits and sustainable development. Therefore, step 4 serves as a key bridge in the overall program, connecting data analysis with actual management and improving the overall efficiency of the system.

[0100] See also Figure 2 , a lifting cage anchoring device management system, comprising:

[0101] A parameter acquisition module is used to collect the environmental parameters and GPS position of the lifting cage anchoring device in real time, and calculate the displacement data of the device through the GPS position, wherein the environmental parameters are water level, water flow velocity, wind speed, temperature, pH value and water turbidity;

[0102] The data processing module generates a comprehensive environmental index based on the dimensionless processed water level, water flow velocity, wind speed and temperature data; generates an anchor stability index based on the dimensionless processed flow velocity, wind speed and displacement data of the lifting device; and generates a water quality health index based on the dimensionless processed pH value and water turbidity data;

[0103] The comprehensive index calculation module is used to combine the comprehensive environmental index, anchor stability index and water quality health index, conduct correlation analysis, and generate a comprehensive evaluation index that reflects the overall status of the system;

[0104] The comprehensive analysis module is used to compare the comprehensive evaluation index with the preset evaluation threshold and formulate corresponding management strategies based on the comparison results.

[0105] The specific values ​​of α, β, γ, δ, μ, ω1, ω2 and ω3 in the formula are generally determined by technical personnel in this field according to actual conditions. The technical personnel in this field collect multiple groups of sample data, and set corresponding preset proportional coefficients for each group of sample data. The set preset proportional coefficients and the collected sample data are substituted into the formula. Through repeated experiments and parameter adjustments, the accuracy of the model output and the rationality of the results are observed, and these factor coefficients are gradually adjusted. The performance and effect of the model under different parameter settings are compared to find the optimal coefficient combination. The calculated factor coefficients are screened and averaged to obtain the values ​​of α, β, γ, δ, μ, ω1, ω2 and ω3.

[0106] In addition, the size of the preset factor coefficient is to quantify each parameter to obtain a specific value. In order to facilitate subsequent comparison, the size of the coefficient depends on the amount of sample data and the preset proportional coefficient initially set by technical personnel in this field for each set of sample data. It is not unique as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0107] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
