Description

Technical Field

[0001] This invention relates to the field of aquaculture health and information technology, and in particular to an adaptive sterilization intensity control method, device and electronic equipment. Background Technology

[0002] The aquaculture environment directly supports the life and growth of farmed aquatic products, and its quality directly affects the health and production efficiency of these products. To maintain the health of farmed aquatic products, sterilization techniques are often used to control the concentration of active pathogenic microorganisms in the aquatic environment. Current methods often involve completely sterilizing the aquaculture water and then recycling it to reduce the risk of disease. However, these methods have shortcomings. First, they are not suitable for open water aquaculture scenarios with high background concentrations of active pathogenic microorganisms, such as large bodies of water and marine ranches. Second, current methods neglect the establishment and function of the aquatic products' own immune barriers. Finally, current methods ignore the dynamic balance among beneficial microbial communities in the aquatic environment, especially nitrifying bacteria. Using full-power sterilization can lead to an imbalance in the beneficial bacterial community in the water, and the recovery time after this imbalance is long, affecting the health of the aquatic products' gut and other internal environments.

[0003] In the operation of aquaculture facilities such as factory farming and aquaponics systems, equipment such as circulating water pumps and sterilization filtration devices are the main sources of energy consumption in the aquaculture process. If they operate at full load or constant power throughout the day, energy consumption is quite high, significantly reducing the economic benefits for farmers. Currently, physical sterilization and desiccation technologies such as ultraviolet light, filtration, electrostatic adsorption, heating sterilization, and ionizing radiation are often combined and applied to the elimination of microorganisms and disease control in aquaculture water environments. Their energy-saving and environmental protection efforts mainly focus on improving the efficiency of functional components. For example, CN114600821B discloses an energy-saving method that uses multiple treatment modes at different times. It utilizes the significant differences in water quality before and after feeding, during and after day and night, and before and after water treatment to implement different time-based treatment modes, while also operating at full load during the sterilization stage. Furthermore, according to the ultraviolet dose-inactivation rate curve, the maximum irradiation dose and energy consumption are required for complete inactivation. However, the sterilization devices and water circulation power in the sterilization stage typically maintain continuous operation after a fixed start-up, without considering adjustments for changes in sterilization intensity. The above analysis shows that it still has unique advantages and room for innovative development in terms of sterilization intensity and control timing.

[0004] In view of the above problems, the existing methods for killing pathogenic microorganisms in aquaculture water environments are not suitable for the development goal of green and clean water, and there is an urgent need for a more scientific, reasonable and targeted method for controlling the intensity of sterilization. Summary of the Invention

[0005] This invention provides an adaptive bactericidal intensity control method, device, and electronic device to solve the problem in the prior art of lacking a scientific and reasonable, targeted bactericidal intensity control method for pathogenic microorganisms in aquaculture water.

[0006] In a first aspect, the present invention provides an adaptive bactericidal intensity control method, comprising:

[0007] Step 110: Obtain multiple water quality index parameters of the aquaculture water environment within a preset time period and the actual concentration value of the target pathogenic microorganism at the current moment;

[0008] Step 120: Based on the immune balance equation of the target aquatic product under the multiple water quality index parameters within the preset time period, determine the maximum tolerable concentration value of the target pathogenic microorganism.

[0009] Step 130: Based on the preset safe concentration threshold of the target pathogenic microorganism, the maximum tolerable concentration value, and the actual concentration value, determine the concentration killing amount of the target pathogenic microorganism;

[0010] Step 140: Based on the concentration kill dose, dynamically adjust the sterilization process parameters in stages to sterilize the aquaculture water environment;

[0011] Step 150: Repeat steps 110-140 to complete the adaptive sterilization process.

[0012] According to an adaptive bactericidal intensity control method provided by the present invention, the immune balance equation of the target pathogenic microorganism on the target aquatic product under the conditions of the multiple water quality index parameters within the preset time period is determined in the following manner:

[0013] Based on the aforementioned multiple water quality parameters, the infectivity of the target pathogenic microorganism within the preset time period is determined;

[0014] Based on the aforementioned multiple water quality index parameters, the anti-infection ability of the target aquatic product within the preset time period is determined;

[0015] Based on the infectivity and the anti-infection ability, the immune balance equation of the target pathogenic microorganism on the target aquatic product is determined under the conditions of the multiple water quality index parameters within the preset time period.

[0016] According to an adaptive bactericidal intensity control method provided by the present invention, determining the concentration kill amount of the target pathogenic microorganism based on a preset safe concentration threshold, the maximum tolerable concentration value, and the actual concentration value includes:

[0017] The moment when the result of the immune balance equation is zero is defined as the moment when the target pathogenic microorganism is in immune balance with the target aquatic product.

[0018] Based on the immune equilibrium equation at immune equilibrium, the maximum tolerated concentration of the target pathogenic microorganism is determined.

[0019] The difference between the maximum tolerable concentration value and the preset safe concentration threshold is calculated to obtain the actual concentration control target value of the target pathogenic microorganism.

[0020] The difference between the actual concentration value and the actual concentration control target value is calculated to obtain the actual concentration kill amount of the target pathogenic microorganism.

[0021] According to the adaptive sterilization intensity control method provided by the present invention, in step S140, the sterilization process parameters are dynamically controlled in stages based on the concentration of sterilization dose to sterilize the aquaculture water environment, including:

[0022] If the concentration kill dose is greater than zero, the sterilization intensity level is determined based on the concentration kill dose and the preset safe concentration threshold.

[0023] Based on the function between the inactivation rate and the ultraviolet dose, the sterilization power and influent flow rate are determined for different sterilization intensity levels.

[0024] Based on the sterilization power and water inflow rate at different sterilization intensity levels, the aquaculture water environment is dynamically sterilized.

[0025] According to the adaptive bactericidal intensity control method provided by the present invention, in step S1401, determining the bactericidal intensity level based on the concentration kill amount and the preset safety concentration threshold includes:

[0026] If the concentration kills more than the preset safe concentration threshold by a first preset multiple, then the sterilization intensity level is determined to be a first-level sterilization intensity level.

[0027] If the concentration kills less than the first preset multiple of the preset safe concentration threshold, and greater than the second preset multiple of the preset safe concentration threshold, then the sterilization intensity level is determined to be a level two sterilization intensity level.

[0028] If the concentration kills less than the preset safe concentration threshold of the second preset multiple, then the sterilization intensity level is determined to be a level three sterilization intensity level.

[0029] According to the adaptive sterilization intensity control method provided by the present invention, in step S1402, the sterilization power and influent flow rate at different sterilization intensity levels are determined based on the inactivation rate and ultraviolet dose, including:

[0030] If the sterilization intensity level is the first sterilization intensity level, then the first sterilization power and the first inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, respectively using the power value corresponding to the increased sterilization irradiation and the reduced water pump inlet speed value as the first sterilization power and the first inlet water flow rate.

[0031] If the sterilization intensity level is the secondary sterilization intensity level, then the second sterilization power and the second inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, respectively using the power value corresponding to the normal sterilization irradiation value and the normal water pump inlet speed value as the second sterilization power and the second inlet water flow rate.

[0032] If the sterilization intensity level is the first-level sterilization intensity level, then the third sterilization power and the third inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, respectively using the power value corresponding to the corresponding reduced sterilization irradiation and the water pump inlet speed as the third sterilization power and the third inlet water flow rate.

[0033] The function of inactivation rate and ultraviolet dose is based on a pre-constructed ultraviolet dose-inactivation rate curve.

[0034] According to the adaptive sterilization intensity control method provided by the present invention, in step S1403, when dynamically sterilizing the aquaculture water environment based on the sterilization power and water inflow rate at different sterilization intensity levels, the following steps are performed for the sterilization power and water inflow rate:

[0035] If the sterilization intensity level is the first-level sterilization intensity level, then the aquaculture water environment is sterilized according to the first sterilization power and the first influent flow rate; the first sterilization power is the sterilization power at the first-level sterilization intensity level, and the first influent flow rate is the influent flow rate at the first-level sterilization intensity level.

[0036] If the sterilization intensity level is the secondary sterilization intensity level, then the aquaculture water environment is sterilized according to the second sterilization power and the second influent flow rate; the second sterilization power is the sterilization power at the secondary sterilization intensity level, and the second influent flow rate is the influent flow rate at the secondary sterilization intensity level.

[0037] If the sterilization intensity level is the third sterilization intensity level, then the aquaculture water environment is sterilized according to the third sterilization power and the third influent flow rate; the third sterilization power is the sterilization power at the third sterilization intensity level, and the third influent flow rate is the influent flow rate at the third sterilization intensity level.

[0038] Secondly, this invention also provides an adaptive sterilization intensity control device, including a power supply module, a water environment monitoring module, a model module, a maximum tolerable concentration calculation module, a concentration kill dose calculation module, a control module, a sterilization intensity grading control module, an ultraviolet sterilization power adjustment module, and a flow control module such as a water pump variable frequency motor. Among these,

[0039] The water environment monitoring module is used to monitor and acquire multiple water quality indicators and parameters of the aquaculture water environment within a preset time period, as well as the actual concentration value of the target pathogenic microorganism at the current moment.

[0040] The model module stores the immune balance equation, inactivation rate and UV dose function of the target pathogenic microorganism on the target aquatic product under water quality parameters, as well as the constant values ​​of the infectivity and anti-infection ability determined by the structure of the target aquatic product in the immune balance equation; the optimal intermittent time value, the preset safe concentration threshold, and also stores the treatment volume, treatment time, types of pathogens to be prevented, and structural parameters of the UV sterilization device, and completes the corresponding updates.

[0041] The maximum tolerable concentration calculation module is used to calculate and determine the maximum tolerable concentration value of the target pathogenic microorganism based on the immune balance equation of the target aquatic product under the corresponding environment of the multiple water quality index parameters within the preset time period.

[0042] The concentration kill amount calculation module is used to calculate the kill amount of the target pathogenic microorganism based on the spatial water quality parameters obtained by the water environment monitoring module, the concentration value of the target pathogenic microorganism, and the maximum tolerable concentration value calculated by the maximum tolerable concentration calculation module.

[0043] The control module is used to execute the above methods to complete the adaptive sterilization process.

[0044] The sterilization intensity grading and control module is used to dynamically adjust the sterilization process parameters in stages based on the concentration of sterilization, and guide the ultraviolet sterilization power adjustment module and the flow control module such as the water pump frequency conversion motor to sterilize the aquaculture water environment.

[0045] Thirdly, the present invention provides an apparatus comprising an electronic device, the electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the program, implements the steps of any of the above-described adaptive sterilization intensity control methods.

[0046] Fourthly, the present invention also provides a medium comprising a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the above-described adaptive sterilization intensity control methods.

[0047] The adaptive sterilization intensity control method, device, and electronic equipment provided by this invention consider the dynamic balance of the infection process between the target pathogenic microorganism and the target aquatic product as water quality changes. It introduces an immune balance equation for the target pathogenic microorganism and the target aquatic product under a specific water quality environment to determine the maximum tolerable concentration of the target pathogenic microorganism. Based on the preset safe concentration threshold, the maximum tolerable concentration, and the actual concentration of the target pathogenic microorganism, it determines the concentration-killing amount of the pathogen. Furthermore, it dynamically adjusts the sterilization process parameters based on the concentration-killing amount to sterilize the aquaculture environment, improving the adaptability, targeting, and process-orientation of sterilization control. This approach is energy-saving, green, efficient, and scientifically sound. In addition, when the aquatic product's tolerance to the target pathogenic microorganism is currently high under a specific water quality environment, the sterilization intensity can be adaptively and appropriately reduced. Sterilization is only necessary when the water environment causes a decrease in the target aquatic product's tolerance to the target pathogenic microorganism and a worsening of the infection process. This maximizes the utilization of the target aquatic product's own immune system and the influence of the water environment on pathogen infectivity, effectively reducing the sterilization intensity and energy consumption of the water body.

[0051] Figure 3 This is a schematic diagram of the adaptive sterilization intensity control device provided by the present invention.

[0052] Figure 4 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] The terms "first," "second," etc., used in this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein.

[0055] The following is combined with Figures 1-4 This invention describes an adaptive bactericidal intensity control method, apparatus, and electronic device.

[0056] The adaptive sterilization intensity control method provided in this invention is based on an adaptive sterilization intensity control device, system, and medium. Since existing sterilization process control mainly operates at full power, to effectively utilize the immune barrier of aquatic products and reduce energy consumption in aquaculture facilities, the adaptive sterilization intensity control method provided in this invention introduces the concept of the maximum pathogenic microorganism tolerance concentration that varies with aquatic environmental parameters. This enables extended control of the sterilization process over time, transforming constant power (intensity) sterilization or periodic on / off sterilization into intermittent variable power (intensity) sterilization that adapts to the aquatic environment for shorter periods. By dynamically adjusting and reducing the pathogenic microorganism concentration and kill rate per unit time, energy savings are possible, and the sterilization intensity and control timing during the sterilization process are optimized, achieving stable control of multiple cycles of intermittent sterilization.

[0057] The advantages of this invention are that, in response to problems such as frequent sterilization in aquaculture water use, low automation of sterilization duration and intensity control, and excessive sterilization dosage disrupting the beneficial bacterial balance of the aquaculture water environment, this embodiment utilizes the maximum tolerated concentration of pathogenic microorganisms that varies with water quality parameters to implement variable intensity sterilization, combined with automatic control technology, thereby improving sterilization accuracy and reducing damage to the aquaculture water microbial environment.

[0058] This invention describes the adaptive sterilization intensity control method using an adaptive sterilization intensity control device as the executing entity.

[0059] Combination Figure 1 and Figure 2 , Figure 1 This is one of the flowcharts illustrating the adaptive bactericidal intensity control method provided by the present invention. Figure 2This is the second flowchart of the adaptive bactericidal intensity control method provided by the present invention.

[0060] like Figure 1 As shown, the method includes the following:

[0061] Step S110: Obtain multiple water quality index parameters of the aquaculture water environment within a preset time period and the actual concentration value of the target pathogenic microorganism at the current moment;

[0062] Step S120: Based on the immune balance equation of the target aquatic product under the multiple water quality index parameters within the preset time period, determine the maximum tolerable concentration value of the target pathogenic microorganism.

[0063] Step S130: Based on the preset safe concentration threshold of the target pathogenic microorganism, the maximum tolerable concentration value, and the actual concentration value, determine the concentration killing amount of the target pathogenic microorganism;

[0064] Step S140: Based on the concentration kill amount, dynamically adjust the sterilization process parameters in stages to sterilize the aquaculture water environment;

[0065] Step S150, repeat steps S110-S140 to complete the adaptive sterilization process.

[0066] It should be noted that this method generates the maximum tolerable pathogen concentration by adjusting the sterilization intensity in stages based on the dynamic balance of infection between "pathogenic microorganisms and target aquatic products" as water quality changes. The technical principle is to control the infectivity that changes with water quality conditions within the dynamic balance equation, thus maintaining the health of aquatic products.

[0067] like Figure 2 As shown, the process of one embodiment is described below:

[0068] Specifically, the adaptive sterilization intensity control device determines the aquaculture water environment that requires sterilization intensity control, and obtains the target aquatic product information and target pathogen information in the aquaculture water environment. In this way, it determines the values ​​of various constant indicators in the infectivity balance equation, and generates the subsequent maximum tolerated concentration and concentration killing amount based on the equation.

[0069] Based on step 110, the adaptive sterilization intensity control device acquires water quality index parameters of the aquaculture water environment within a preset time period. The preset time period is set by experience based on actual conditions, such as 1 hour, 10 minutes, or 5 minutes.

[0070] It should be noted that the water quality space comprised of multiple water quality indicators within the aquaculture environment and the values ​​of these indicators is called the water quality parameter space. These multiple water quality indicators include, but are not limited to, water temperature, pH, dissolved oxygen, nitrate, light conditions, and turbidity. In one embodiment, the water quality parameter space can be represented as a set, W. φ =W(x, y, z,…), where x, y, z, …∈R+, to ensure the survival rate and quality of farmed aquatic products, the parameter values ​​corresponding to each water quality indicator should be within the suitable survival range for the target aquatic products. Here, x, y, z are the selected main water quality indicators, and for simplicity, W is used. ijk… The water quality parameter is represented by x. i , y j , z k Let i, j, k ≤ n, and n be a positive integer.

[0071] Therefore, the water quality parameter vector of the aquaculture water environment within the preset time period is composed of multiple water quality index parameters within the preset time period. These water quality index parameters can be obtained by measuring the water quality indicators, and the water quality parameter space is mainly for the simple representation of water quality index parameters.

[0072] At the same time, the adaptive sterilization intensity control device also needs to obtain the actual concentration value of the target pathogenic microorganism at the current moment.

[0073] Based on step 120, the adaptive sterilization intensity control device determines the immune balance equation of the target pathogenic microorganism on the target aquatic product under the water quality parameter space of the aquaculture water environment within a preset time period, that is, based on multiple water quality index parameters of the aquaculture water environment within a preset time period.

[0074] Furthermore, the adaptive sterilization intensity control device determines the moment when the target pathogenic microorganism is in immune equilibrium with the target aquatic product under the current water quality parameter space, and the corresponding concentration value when immune equilibrium is present, i.e., the maximum tolerable concentration value, based on multiple water quality index parameters under the current water quality parameter space.

[0075] Based on step 130, the adaptive sterilization intensity control device determines the concentration killing amount between the actual concentration value of the target pathogenic microorganism and the actual concentration control target value, based on the maximum tolerable concentration value when the target pathogenic microorganism is in immune balance with the target aquatic product, its specific preset safe concentration threshold, and its actual concentration value.

[0076] Based on step 140, the adaptive sterilization intensity control device further determines the sterilization intensity level required for the sterilization process based on the concentration kill amount.

[0077] After determining the sterilization intensity level, the adaptive sterilization intensity control device dynamically adjusts the sterilization process parameters in stages to perform intermittent sterilization on the aquaculture water environment.

[0078] It should be noted that the advantages of this invention are also reflected in the following three aspects: the target baseline for controlling the concentration of the target pathogen can be adaptively adjusted according to changes in water quality parameters; the sterilization intensity level can be adaptively adjusted according to changes in water quality parameters; and changes in control methods, duration, intensity, and other control quantities can be adaptively adjusted according to the concentration and sterilization amount, thereby making the sterilization process more intelligent and energy-saving.

[0079] Based on step 150, further, after performing intermittent sterilization treatment with a fixed sterilization cycle T, the adaptive sterilization intensity control device determines whether the task of killing the concentration within this period has been completed.

[0080] If the target concentration kill amount has not been achieved at the current moment, continue with the intermittent sterilization treatment for a fixed sterilization cycle T, and then determine whether the target concentration kill amount for this period has been achieved.

[0081] If the concentration kill target has been achieved at the current moment, then confirm whether the control period has ended. If the control period has ended, then end the sterilization intensity control process. If the control period has not ended, the adaptive sterilization intensity control device returns to the first step and repeats the above steps 110-140, that is, obtain the water quality parameters of the aquaculture water environment within the preset time period and the actual concentration value of the target pathogenic microorganism at the current moment, and continue to execute the sterilization intensity control process to achieve dynamic health management during the aquaculture process.

[0082] The adaptive sterilization intensity control method provided by this invention considers the dynamic balance of the infection process between the target pathogenic microorganism and the target aquatic product as water quality changes. It introduces an immune balance equation for the target pathogenic microorganism and the target aquatic product under a specific water quality environment to determine the maximum tolerable concentration of the target pathogenic microorganism. Based on a preset safe concentration threshold, the maximum tolerable concentration, and the actual concentration, it determines the concentration-killing amount of the target pathogenic microorganism. Furthermore, it dynamically adjusts the sterilization process parameters based on the concentration-killing amount to sterilize the aquaculture environment, improving the adaptability, specificity, and process-orientation of sterilization control. This method is energy-saving, green, efficient, and scientifically sound. In addition, when the target aquatic product has a high tolerance to the target pathogenic microorganism under a specific water quality environment, the sterilization intensity can be adaptively and appropriately reduced. Sterilization is only necessary when the water environment causes a decrease in the target aquatic product's tolerance to the target pathogenic microorganism and a worsening of the infection process. This maximizes the utilization of the target aquatic product's own immune system and the influence of the water environment on pathogen infection activity, thereby effectively reducing the sterilization intensity and energy consumption of the water body.

[0083] In some embodiments, based on the content of step 120, the immune balance equation and parameters of the target pathogenic microorganism on the target aquatic product under the conditions of the multiple water quality index parameters within the preset time period are pre-constructed and specifically determined in the following manner:

[0084] S1201, Based on the multiple water quality index parameters, determine the infectivity of the target pathogenic microorganism within the preset time period;

[0085] S1202, Based on the multiple water quality index parameters, determine the anti-infection ability of the target aquatic product within the preset time period;

[0086] S1203, based on the infectivity and the anti-infection ability, determine the immune balance equation of the target pathogenic microorganism on the target aquatic product under the conditions of the multiple water quality index parameters within the preset time period.

[0087] Specifically, in S1201, the adaptive sterilization intensity control device determines the infectivity of the target pathogenic microorganism within a preset time period based on multiple water quality index parameters within a preset time period.

[0088] In one embodiment, U a (W, t) represents the infectivity of the target pathogenic microorganism a at the water quality parameter space W within a preset time period t, where infectivity represents the infection rate of the target aquatic product by a fixed intake of the target pathogenic microorganism.

[0089] U a (W ijk… , t) indicates that the target pathogenic microorganism a is within a preset time period t, and the water quality parameter space is W. ijk… Infectivity at the site. U a (W ijk.... The specific value of the infectivity at point (t) can be determined experimentally or approximated using a formula, as shown below:

[0090]

[0091] Among them, W 000… P represents the optimal spatial value representing the infection process of the target pathogenic microorganism a; a As the first transformation matrix, since the infection process of the target pathogen a exhibits different trends below and above the optimum zone, P can be transformed according to these different trends. a Piecewise representation, i.e., P a It is a piecewise function, since P a U is a piecewise function. a (W ijk… , t) is also a piecewise function.

[0092] Meanwhile, according to S1202, the adaptive sterilization intensity control device determines the anti-infection ability of the target aquatic product within a preset time period based on multiple water quality index parameters within a preset time period.

[0093] In one embodiment, V b (W, t) represents the target aquatic product b (specifically involving the variety and specifications of the aquatic product) within a preset time period t, where the water quality parameter space is W. ijk…… The anti-infection ability refers to the maximum concentration of pathogenic microorganisms that prevents the target aquatic product from developing the disease in aquatic environments with different concentrations of pathogenic microorganisms.

[0094] V b (W ijk… , t) indicates that the target aquatic product b, within a preset time period t, has a water quality parameter space of W. ijk… The area's resistance to infection. V b (W ijk… The specific value of the anti-infective ability at point (t) can be determined experimentally or approximated using a formula, as shown below:

[0095]

[0096] Among them, W 000… P represents the optimal spatial value for the anti-infection process of target aquatic product b; b For the second transformation matrix, since the anti-infection process of target aquatic product b exhibits different trends below and above the optimum zone, P can be transformed according to these different trends. b Piecewise representation, i.e., P b It is a piecewise function, since P b For a piecewise function, V b (W ijk… , t) is also a piecewise function.

[0097] Furthermore, according to S1203, the adaptive sterilization intensity control device determines the immune balance equation of the target aquatic product under multiple water quality index parameters within a preset time period based on infectivity and anti-infection ability.

[0098] In one embodiment, the immune balance equation of the target pathogenic microorganism on the target aquatic product during a preset time period is as follows:

[0099]

[0100] in, This indicates that the target pathogenic microorganism a affects the target aquatic product b within a preset time period t, and the water quality parameter value is W. ijk…The infectivity of the target pathogen a is denoted as c; the concentration of the target pathogen a within a preset time period t is denoted as f; the amount of water intake or contact of the target aquatic product b with the aquaculture environment per unit time is denoted as f; and the total number of equivalent immune factors is denoted as k. Both f and k are constants determined by the structure of the target aquatic product b and can be determined through a large amount of experimental data.

[0101] It should be noted that, This represents the concentration value of the target pathogenic microorganism a within a preset time period t. This concentration is determined by pathogen detection reagents or acquired in real time by a biosensor. The value is manually input or input to the adaptive sterilization intensity control device and used as a feedback monitoring indicator for the adaptive sterilization intensity control device.

[0102] This invention, through comprehensive analysis of the infectivity of the target pathogenic microorganism and the anti-infectivity of the target aquatic products, can effectively assess and manage disease risks during the aquaculture process, ensuring the health and safety of farmed aquatic products.

[0103] In some embodiments, the concentration-killing dose of the target pathogenic microorganism is determined based on the preset safe concentration threshold, the maximum tolerable concentration value, and the actual concentration value described in steps S120 and S130. The specific content of this process includes:

[0104] S121, the moment when the result of the immune balance equation is zero is determined as the moment when the target pathogenic microorganism has an immune balance with the target aquatic product;

[0105] S122, Based on the immune balance equation at immune equilibrium, determine the maximum tolerable concentration value of the target pathogenic microorganism;

[0106] S131, calculate the difference between the maximum tolerable concentration value and the preset safe concentration threshold to obtain the actual concentration control target value of the target pathogenic microorganism;

[0107] S132, calculate the difference between the actual concentration value and the actual concentration control target value to obtain the actual concentration killing amount of the target pathogenic microorganism.

[0108] Specifically, the adaptive sterilization intensity control device determines the moment when the result of the immune balance equation is zero as the moment when the target pathogenic microorganism has an immune balance with the target aquatic product.

[0109] The adaptive sterilization intensity regulation device determines the maximum tolerable concentration of the target pathogenic microorganism based on the immune equilibrium equation during immune equilibrium.

[0110] In one embodiment, based on steps S121 and S122, there exists a specific water quality parameter space W0 and time t0 such that the target pathogenic microorganism a is in immune equilibrium with the target aquatic product b, satisfying... ,Right now Then there is,

[0111] ,

[0112] That is, the target aquatic product in the water quality parameter space The maximum tolerable concentration of the target pathogenic microorganism is given below; then the corresponding water quality conditions for each time period are... The next corresponds to one Subtract the preset safe concentration threshold from this value. This refers to the actual sterilization intensity control, meaning the concentration of the target pathogenic microorganisms in the target water body should be controlled within ( ). )under.

[0113] The aforementioned balance formula can be considered a dynamic immune balance model based on water quality indicators. The concentration values ​​generated by this model are used to regulate the sterilization intensity, effectively reducing the amount of sterilization required. The concentration of the target pathogen can be acquired in real time using a pathogen concentration sensor. If the concentration of the corresponding target pathogen cannot be acquired in real time by a sensor, it can be manually measured and input or remotely input. The remote input value can be generated by a numerical change simulation model based on an approximate input concentration to achieve energy-saving control. Specifically, in some scenarios, the background concentration is a constant value.

[0114] Further, based on step S131, the adaptive sterilization intensity control device calculates the difference between the maximum tolerable concentration value and the preset safe concentration threshold to obtain the actual concentration control target value of the target pathogenic microorganism, which can be expressed as: The preset safe concentration threshold is set according to the actual situation, and is generally no less than 20% of the maximum tolerable concentration value, or it can be a fixed value.

[0115] Subsequently, based on step S132, the adaptive sterilization intensity control device calculates the difference between the actual concentration value of the target pathogenic microorganism and the actual concentration control target value to obtain the actual concentration killing amount of the target pathogenic microorganism, which can be expressed as: .

[0116] It should be noted that, in one embodiment, when targeting and eliminating two or more pathogenic microorganisms, the concentrations of the eliminated pathogenic microorganisms are summed and multiplied by a correction factor to achieve a synergistic effect, specifically as follows: .in, It is the sum of the concentrations and kill amounts of m pathogenic microorganisms; This represents the correction factor, which is generally greater than 1 and can be set to 1.2. It is adjusted based on the synergistic effect of multiple diseases and is determined by empirical values. This indicates the equivalent concentration of killing effect on a variety of pathogenic microorganisms as a whole.

[0117] This invention, based on the immune balance equation under the condition of immune balance between the target pathogenic microorganism and the target aquatic product, determines the concentration of the target pathogenic microorganism to be killed, and then regulates the sterilization intensity of the aquaculture water environment based on the concentration of the target pathogenic microorganism. This achieves dynamic sterilization intensity regulation based on the adaptability of the aquaculture water environment. Through the dynamic balance of pathogen infection and the adjustment of sterilization intensity according to water quality changes, energy consumption can be effectively saved, thus achieving reasonable and targeted sterilization of the aquaculture water environment.

[0118] In some embodiments, based on the content of step S140, the sterilization intensity of the aquaculture water environment is adjusted based on the concentration of sterilization. The specific content of this process includes:

[0119] S141, If ​​the concentration kill amount is greater than zero, then the sterilization intensity level is determined based on the concentration kill amount and the preset safe concentration threshold;

[0120] S142, Based on the function between the inactivation rate y and the ultraviolet dose x, determine the sterilization power and influent flow rate under different sterilization intensity levels;

[0121] S143, based on the sterilization power and water inflow rate at different sterilization intensity levels, the aquaculture water environment is dynamically sterilized.

[0122] It should be noted that the function of ultraviolet dose x and inactivation rate y mentioned in this step is based on a pre-constructed ultraviolet dose-inactivation rate curve. Taking an ultraviolet water disinfection device as an example, the specific steps are as follows:

[0123] First, a characteristic curve for the validation dose is constructed. According to the standard "Test Method for Ultraviolet Dose of Ultraviolet Water Disinfection Equipment" (GB / T 32091-2015), the adjustable parameters of ultraviolet disinfection equipment should include the water flow rate Q and the output power P of the ultraviolet lamps. The validation dose of ultraviolet water disinfection equipment is related to factors such as the ultraviolet transmittance of the water, the ultraviolet light intensity, the flow rate, and the number of lamps. Based on the experimental data of the disinfection equipment dose test and the formula RED=10... a ×A 254 b ×P c ×Q d ×B eBy using linear regression to calculate the constants a, b, c, d, and e, the characteristic curve of the ultraviolet water disinfection equipment can be obtained. In the formula, RED represents the validation dose of the ultraviolet water disinfection equipment; A 254 Indicates UV of water body 254 Absorbance; P represents the output power of the UV water disinfection equipment; Q represents the corresponding flow rate of the equipment; B represents the number of UV module units (only for channel-type disinfection equipment, this is 1 for pipe-type disinfection equipment); a, b, c, d, and e are constants. Understandably, RED represents the equation constrained by P and Q. Among them, water quality affects A... 254 The value is mainly affected by the turbidity of the water, specifically the UV value. 254 Absorbance = 1 - UV transmittance (UVT), which is affected by water quality parameters. Therefore, this effect is also considered in the acquired water quality parameters. The validation dose is affected by equipment scaling and aging, and is referred to as the effective validation dose. No specific distinction is made between the two in this embodiment, but they are detailed in the standard. Furthermore, in this embodiment, the validation dose RED is equivalent to the actual UV dose x.

[0124] Furthermore, based on the UV dose-inactivation rate curve, a function relating UV dose x and inactivation rate y is constructed. Since the inactivation rate is affected by the UV dose, to dynamically adjust the UV dose according to the inactivation rate and to explain the relationship between the sterilization power P and the influent flow rate Q during water quality control, a function relating UV dose x and inactivation rate y is constructed based on the "UV dose-inactivation rate curve" described in the aforementioned standard, denoted as y=f(x) (x∈A, A≥0), with a range of 0-100%. Correspondingly, its inverse function can be expressed as x=f -1 (y)=RED. Then there is a relationship equation between the inactivation rate y and the sterilization power P and the influent flow rate Q, i.e., y=f(P, Q)=f(10 a ×A 254 b ×P c ×Q d) This formula serves as the basis for adjusting the values ​​of the two parameters, sterilization power P and influent flow rate Q, during water quality control. The inactivation rate, used in this embodiment, represents the ratio of the concentration of sterilized material to the initial concentration, which differs from the logarithmic value of sterilization. The inactivation rate is calculated as [1 - 10^(logarithmic value of sterilization)] × 100%. Thus, the function relating the inactivation rate y and the ultraviolet dose x is complete.

[0125] It should be noted that before proceeding to step 140, the actual concentration of the bactericidal dose must be determined. If the actual concentration of the target pathogenic microorganism being killed is greater than zero, the adaptive bactericidal intensity control device determines the bactericidal intensity level based on the relationship between the concentration of the bactericidal dose and the preset safe concentration threshold. This step is carried out when the actual concentration of the target pathogenic microorganism being killed is greater than zero.

[0126] Regarding the determination of the sterilization intensity level based on the concentration kill dose and the preset safety concentration threshold in step S141 above, the specific content of this process includes:

[0127] If the concentration kills more than the preset safe concentration threshold by a first preset multiple, then the sterilization intensity level is determined to be a first-level sterilization intensity level.

[0128] If the concentration kills less than the first preset multiple of the preset safe concentration threshold, and greater than the second preset multiple of the preset safe concentration threshold, then the sterilization intensity level is determined to be a level two sterilization intensity level.

[0129] If the concentration kills less than the preset safe concentration threshold of the second preset multiple, then the sterilization intensity level is determined to be a level three sterilization intensity level.

[0130] Specifically, if the concentration of the target pathogenic microorganism kills (or equivalent concentration of lethal dose) If the concentration exceeds the preset safe concentration threshold by a first preset multiple, the adaptive sterilization intensity control device determines the sterilization intensity level to be the first-level sterilization intensity level. The first preset multiple is set according to the actual situation and can be set to 1. In this case, the concentration kill amount is greater than the preset safe concentration threshold c0. Under this case, the water quality changes significantly and the sterilization intensity needs to be further increased to reduce the change in infectivity balance caused by the water quality change to a controllable range.

[0131] Furthermore, if the concentration of the target pathogenic microorganism kills... (or equivalent concentration of lethal dose) If the concentration is less than the first preset multiple of the preset safe concentration threshold and greater than the second preset multiple of the preset safe concentration threshold (i.e., the second preset multiple of the preset safe concentration threshold < the concentration kill amount < the first preset multiple of the preset safe concentration threshold), the adaptive sterilization intensity control device determines the sterilization intensity level to be level two. The second preset multiple is set according to the actual situation and can be set to 0.5 times. In this case, the 0.5 times preset safe concentration threshold c0 < the concentration kill amount < the preset safe concentration threshold c0. Under this condition, the water quality change is not significant, and the change in infectivity balance caused by the change in water quality can be kept within a controllable range by using normal sterilization intensity.

[0132] Furthermore, if the concentration of the target pathogenic microorganism kills... (or equivalent concentration of lethal dose) If the concentration is less than the second preset multiple of the preset safe concentration threshold, i.e., the concentration kill amount is less than the second preset multiple of the preset safe concentration threshold c0, the adaptive sterilization intensity control device determines the sterilization intensity level to be level three. If the second preset multiple is set to 0.5 times, then the concentration kill amount is less than 0.5 times the preset safe concentration threshold c0. In this case, it is considered that the water quality change is small, and the sterilization intensity can be reduced to keep the change in infectivity balance caused by the water quality change within a controllable range.

[0133] Based on the function between the inactivation rate y and the ultraviolet dose x described in step S142 above, the sterilization power and influent flow rate under different sterilization intensity levels are determined.

[0134] In this embodiment, the adaptive sterilization intensity control device is divided into three levels based on a function of ultraviolet dose x and inactivation rate y. Correspondingly, the first sterilization power and first inlet water flow rate are determined sequentially for the first sterilization intensity level, the second sterilization power and second inlet water flow rate for the second sterilization intensity level, and the third sterilization power and third inlet water flow rate for the third sterilization intensity level. Optionally, the second sterilization power can be considered to be half of the standard power in the prior art, and the inlet water flow rate can be half of the inlet water speed typically set by the water pump.

[0135] It should be noted that the inactivation rate y and the ultraviolet dose x are functions of each other, i.e., equations based on the inactivation rate y, sterilization power P, and influent flow rate Q. The inactivation rate y is constrained by the sterilization power P and the influent flow rate Q, i.e., x = f -1 (y) =RED=10 a ×A 254 b ×P c ×Q d Therefore, different inactivation rates y correspond to multiple combinations of sterilization power P and influent flow rate Q, which means that they can be divided into more levels according to the function of the inactivation rate y and ultraviolet dose x, while in this example, they are only divided into three groups.

[0136] Specifically, if the sterilization intensity level is the first sterilization intensity level, then the first sterilization power and the first inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, and the power value corresponding to the corresponding increased sterilization irradiation and the reduced water pump inlet speed value are respectively used as the first sterilization power and the first inlet water flow rate.

[0137] If the sterilization intensity level is the secondary sterilization intensity level, then the second sterilization power and the second inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, respectively using the power value corresponding to the normal sterilization irradiation value and the normal water pump inlet speed value as the second sterilization power and the second inlet water flow rate.

[0138] If the sterilization intensity level is the first-level sterilization intensity level, then the third sterilization power and the third inlet water flow rate are determined sequentially according to the function of the inactivation rate y and the ultraviolet dose x, respectively using the power value corresponding to the corresponding reduced sterilization irradiation and the water pump inlet speed as the third sterilization power and the third inlet water flow rate.

[0139] It should be noted that in this step, the influent flow rate can be determined first, and then the corresponding sterilization power P can be determined.

[0140] Regarding the dynamic sterilization of the aquaculture water environment based on the sterilization power and influent flow rate at different sterilization intensity levels as described in step 143 above, the following steps are performed to regulate the sterilization power and influent flow rate:

[0141] If the sterilization intensity level is the first-level sterilization intensity level, then the aquaculture water environment is sterilized according to the first sterilization power and the first influent flow rate; the first sterilization power is the sterilization power at the first-level sterilization intensity level, and the first influent flow rate is the influent flow rate at the first-level sterilization intensity level.

[0142] If the sterilization intensity level is the secondary sterilization intensity level, then the aquaculture water environment is sterilized according to the second sterilization power and the second influent flow rate; the second sterilization power is the sterilization power at the secondary sterilization intensity level, and the second influent flow rate is the influent flow rate at the secondary sterilization intensity level.

[0143] If the sterilization intensity level is the third sterilization intensity level, then the aquaculture water environment is sterilized according to the third sterilization power and the third influent flow rate; the third sterilization power is the sterilization power at the third sterilization intensity level, and the third influent flow rate is the influent flow rate at the third sterilization intensity level.

[0144] Furthermore, the adaptive sterilization intensity control device adjusts the adjustable parameters of the disinfection equipment, including sterilization power P and influent flow rate Q, according to three levels of sterilization power and influent flow rate determined by different sterilization intensity levels, to dynamically sterilize the aquaculture water environment. The sterilization power P and influent flow rate Q are reflected in the adjustment of the number of ultraviolet lamps and the water pump influent speed.

[0145] Specifically, if the sterilization intensity level is Level 1, the adaptive sterilization intensity control device sterilizes the aquatic environment by increasing the sterilization irradiation and decreasing the water pump's inlet speed, based on the first sterilization power and the first inlet water flow rate. In one embodiment, increasing the initial sterilization irradiation can be achieved by arranging multiple ultraviolet lamps to enhance the upper limit of the sterilization irradiation intensity control.

[0146] In another case, if the sterilization intensity level is level two, the adaptive sterilization intensity control device sterilizes the aquatic environment according to the second sterilization power and the second inlet flow rate, that is, using normal sterilization irradiation and normal inlet flow rate.

[0147] In another scenario, if the sterilization intensity level is level three, the adaptive sterilization intensity control device sterilizes the aquatic environment by halving the sterilization irradiation dose and increasing the water pump's inlet speed, based on the third sterilization power and the second inlet water flow rate. In one embodiment, halving the original sterilization irradiation dose can be achieved by halving the use of ultraviolet lamps or adjusting the power to reduce the sterilization irradiation intensity.

[0148] Based on step S150, in Figure 2 In the described process, steps S110-S140 are repeated to complete the adaptive sterilization process. Specifically, if the concentration of the target pathogenic microorganism is less than or equal to zero, the adaptive sterilization intensity control device determines whether the control period has ended.

[0149] Furthermore, if the prevention and control period ends, the adaptive sterilization intensity control device will end the sterilization intensity control process; if the prevention and control period does not end, the adaptive sterilization intensity control device will return to the first step and repeat the above steps 110-140, that is, obtain the spatial water quality parameters of the aquaculture water environment within the preset time period and the actual concentration value of the target pathogenic microorganism at the current moment, and continue to execute the sterilization intensity control process to achieve dynamic health management during the aquaculture process.

[0150] In summary, the embodiments of the present invention are combined with, as follows Figure 2 The process of one embodiment shown illustrates how different sterilization intensities are selected based on the concentration of the bactericidal dose, thereby achieving graded control of the sterilization intensity and further dynamically controlling the sterilization irradiation. This process refines the sterilization process through energy conservation, achieving precise quantitative energy consumption control and thus realizing reasonable and targeted sterilization of the aquatic environment.

[0151] The adaptive sterilization intensity control device provided by the present invention is described below. The adaptive sterilization intensity control device described below and the adaptive sterilization intensity control method described above can be referred to in correspondence.

[0152] Reference Figure 3, Figure 3 This is a schematic diagram of the adaptive sterilization intensity control device provided by the present invention. Figure 3 As shown, the adaptive sterilization intensity control device specifically includes: a power supply module 330, a water environment monitoring module 311, a model module 312, a maximum tolerable concentration calculation module 313, a concentration kill amount calculation module 314, a control module 315, a sterilization intensity grading control module 316, an ultraviolet sterilization power adjustment module 321, and a flow control module 322, including a water pump and variable frequency motor. Among these, the water environment monitoring module 311, model module 312, maximum tolerable concentration calculation module 313, concentration kill amount calculation module 314, control module 315, and sterilization intensity grading control module 316 belong to the low-voltage part 310, while the ultraviolet sterilization power adjustment module 321 and the flow control module 322, including the water pump and variable frequency motor, belong to the high-voltage part 320.

[0153] Specifically, the functions of each module in the adaptive sterilization intensity control device are as follows:

[0154] Power supply module 330 provides the necessary electrical energy for the adaptive sterilization intensity control device to perform its operation;

[0155] The water environment monitoring module 311 is used to monitor and acquire multiple water quality index parameters of the aquaculture water environment within a preset time period, as well as the actual concentration value of the target pathogenic microorganism at the current moment.

[0156] Model module 312 stores the immune balance equation, inactivation rate, and UV dose function of the target pathogenic microorganism on the target aquatic product under water quality parameters. It also stores the infectivity and anti-infective ability constants determined by the structure of the target aquatic product within the immune balance equation, as well as the optimal interval time T and preset safe concentration threshold. It also includes the storage and updating of parameters such as water volume, treatment time, types and concentrations of pathogens to be prevented (which vary with the season and time of day), and structural parameters of the ultraviolet sterilization device. Among these, parameters such as water volume, treatment time, types and concentrations of pathogens to be prevented (which vary with the season and time of day) can be manually input remotely. The remote input values ​​can be generated by a numerical variation simulation model based on approximate input concentrations; the optimal intermittent time T and preset safe concentration thresholds are also included. It can be obtained through experiments based on the actual situation;

[0157] The maximum tolerable concentration calculation module 313 is used to calculate and determine the maximum tolerable concentration value of the target pathogenic microorganism based on the immune balance equation of the target aquatic product under the corresponding environment of the multiple water quality index parameters within the preset time period.

[0158] The concentration kill amount calculation module 314 is used to calculate the concentration kill amount of the target pathogenic microorganism based on the water quality parameters obtained by the water environment monitoring module, the concentration value of the target pathogenic microorganism, and the maximum tolerable concentration value calculated by the maximum tolerable concentration calculation module.

[0159] The control module 315 is used to execute the above method to complete the adaptive sterilization process.

[0160] The sterilization intensity graded control module 316 is used to dynamically control the sterilization process parameters in stages based on the concentration of sterilization, and guide the ultraviolet sterilization power adjustment module and the flow control module such as the water pump frequency conversion motor to sterilize the aquaculture water environment.

[0161] The specific steps for using the device are as follows: the control module 315 executes the above-mentioned regulation method; the water environment monitoring module 311 monitors and acquires water quality parameters and the actual concentration of the target pathogenic microorganism; the acquired parameters are input into the model module 312, and the relevant model is called; the maximum tolerable concentration calculation module 313 calculates the maximum tolerable concentration of the target aquatic product for the target pathogenic microorganism under the current water quality conditions; then the concentration kill amount calculation module 314 calculates and determines the concentration kill amount; then, the sterilization intensity is graded according to the concentration kill amount calculated by the concentration kill amount calculation module 314, which guides the sterilization intensity grading control module 316 to adjust the parameters of the ultraviolet sterilization power adjustment module 321 and the flow control module 322 such as the water pump variable frequency motor to sterilize the water.

[0162] It should be noted that the adaptive sterilization intensity control device provided by the present invention can execute the adaptive sterilization intensity control method described in any of the above embodiments during specific operation, which will not be elaborated in this embodiment.

[0163] Furthermore, the aforementioned adaptive sterilization intensity control device has two typical application forms. One is as an integrated, stand-alone device, such as in relatively independent and enclosed water bodies like traditional pond aquaculture, where the sterilization intensity is controlled based on the aquatic environment through in-situ deployment. The other is as a decentralized device, such as in open / semi-open scenarios like semi-open factory farming or aquaculture vessels, where the main components are distributed to other facilities and equipment for coordinated use.

[0164] Specifically, in one embodiment, for closed-loop applications such as factory-style aquaculture with internal water circulation and traditional pond aquaculture, where the water treatment volume is relatively fixed, an independent in-situ sterilization device is used. Sterilization is regulated based on the internal water quality parameters of the device's location. Using the above method, the device dynamically monitors changes in water quality and the immune balance of pathogen concentrations to control pathogen concentrations and reduce disease occurrence.

[0165] Specifically, in another embodiment, this applies to open / semi-open aquaculture scenarios such as large-scale enclosed culture, deep-sea cage culture, and industrial vessels, where water quality parameters are difficult to adjust and the concentrations of water quality parameters and target pathogens are relatively fixed. Because water quality parameters are difficult to control, the concentration of target pathogens in the water at the inlet needs to be adjusted according to the water quality conditions within the aquaculture facility. In this scenario, the background concentration of pathogens is the biggest influencing factor for disease occurrence, especially when energy supply is insufficient or comprehensive disinfection is not feasible, and traditional comprehensive disinfection is extremely energy-intensive. Therefore, reducing the pathogen concentration based on water quality is particularly important, as this can save energy and improve the disease prevention effect per unit of energy consumption. Understandably, the water body is divided into two parts: the outer water area is designated as the first water area, and the inner water area as the second water area. The actual concentration of the target pathogens can be determined in the first water area, and the water quality parameters can be determined in the second water area. The device uses a rapid sterilization mode to treat the incoming water to build a barrier. The second water body has a high aquaculture density and there are slight but obvious differences in water quality parameters between the inside and outside environment, which reduces the tolerance of the target aquatic products to the target pathogens. Therefore, it is necessary to carry out disinfection treatment according to the water quality parameters of the second water body.
