Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a black soldier fly farming system, management method, and electronic equipment. Background Technology

[0002] Black soldier flies, as a highly valuable resource insect, demonstrate enormous potential in the fields of ecological recycling and resource utilization. Their larvae can efficiently decompose and transform organic waste, such as kitchen waste and livestock manure, into high-quality insect protein and fat. This not only provides a green and environmentally friendly approach to solving the problem of organic waste treatment but also offers a new source of raw materials for industries such as feed and biofuels. Furthermore, the short growth cycle and high reproductive capacity of black soldier flies make large-scale farming a potentially lucrative economic and ecological endeavor, thus attracting increasing attention and research.

[0003] The management of the black soldier fly farming environment has been a persistent obstacle to the industry's development. For example, the existing water supply system lacks water flow during the supply process, and the excrement of black soldier flies can easily have an adverse effect on water quality, thereby affecting the health of the black soldier flies. Summary of the Invention

[0004] The main objective of this invention is to provide a black soldier fly farming system, management method, and electronic equipment, aiming to solve the technical problem of inadequate environmental management in existing black soldier fly farming technologies.

[0005] To achieve the above objectives, in a first aspect, this application provides a black soldier fly larvae farming system, comprising:

[0006] The breeding chamber is equipped with a water supply sponge, the upper surface of which is an inclined water absorption area;

[0007] A water circulation module includes a water storage tank, a water storage pipe disposed in the water storage tank, a power unit disposed on one side of the water storage tank, a water supply pipe connected to the power unit, a first return water pipe, a second return water pipe, and a switching valve. The water supply pipe is connected to the first return water pipe or the second return water pipe through the switching valve, and the water supply sponge is disposed in the second return water pipe.

[0008] The deodorization chamber is equipped with a negative pressure device and a plasma deodorization module. The negative pressure device is configured to drive the odor in the breeding chamber to the plasma deodorization module for deodorization.

[0009] A processor configured to control the operating modes of a black soldier fly farming system, wherein the operating modes include one or more of a water supply mode, a cleaning mode, and a deodorization mode.

[0010] In one possible implementation, the processor is electrically connected to the power unit, switching valve, negative pressure device, and plasma deodorization module; and / or,

[0011] The aquaculture chamber and deodorization chamber are located on the ground, while the water storage chamber is located underground.

[0012] In one possible implementation, the water storage pipe comprises multiple bamboo poles stacked one on top of the other, the diameter of which is no greater than 3 cm; and / or,

[0013] The switching valve includes a drive motor and a flap that is pulsatingly connected to the drive motor. Under the driving action of the drive motor, the flap selectively blocks the first return water pipe and the second return water pipe; and / or,

[0014] The water storage tank is also equipped with a filter screen, which is located on one side of the power unit.

[0015] In one possible implementation, the water supply sponge has a vibrator inside or at its bottom, the vibrator being configured to vibrate and drop black soldier fly larvae onto the floor of the breeding chamber.

[0016] Secondly, this application also provides a method for the management and control of black soldier fly larvae farming, the method comprising:

[0017] Multiple frames of the first target image are obtained by acquiring image data of the water absorption area of ​​the water supply sponge.

[0018] The multi-frame first target image is input into the insect density analysis model to obtain the average insect density within a preset time period.

[0019] When the average density of the insects is greater than or equal to the density threshold, the black soldier fly breeding system is controlled to be in a continuous water supply mode, and the vibrator is controlled to vibrate according to the average density of the insects, wherein the vibrator is located inside the water supply sponge or at the bottom of the water supply sponge.

[0020] When the average density of the insects is less than the density threshold, the black soldier fly breeding system is controlled to switch between water supply mode and cleaning mode in a cyclical manner.

[0021] In one possible implementation, controlling the black soldier fly farming system to be in a continuous water supply mode includes:

[0022] The flap of the control switching valve rotates to connect the water supply pipe with the second return water pipe;

[0023] The operating power of the power unit is determined based on the average density of the insects to obtain the first target power, wherein the average density of the insects is positively correlated with the first target power;

[0024] The power unit is controlled to operate at the first target power to continuously supply water to the water supply sponge.

[0025] In one possible implementation, controlling the vibrator to vibrate based on the average density of the insect body includes:

[0026] The target egg production rate is obtained by estimating the egg production rate of black soldier flies based on the average density of the insects and the environmental parameters in the breeding chamber.

[0027] The vibration parameters of the vibrator are determined based on the target egg production rate to obtain the target vibration parameters, wherein the target vibration parameters include vibration amplitude and vibration frequency;

[0028] The vibrator is controlled to vibrate at the target vibration parameters so that the insect eggs generated in the water absorption area of ​​the water supply sponge are vibrated and dropped onto the ground of the breeding chamber.

[0029] In one possible implementation, the method further includes:

[0030] Multiple frames of second target images are obtained by acquiring image data of the ground of the aquaculture tank;

[0031] Multiple frames of the second target image are input into the larval density analysis model to obtain the average larval density within a preset time period;

[0032] The operating power of the negative pressure device and the plasma deodorization module is determined based on the average larval density to obtain the second operating power and the third operating power.

[0033] The negative pressure device and the plasma deodorization module are controlled to operate at the second operating power and the third operating power, respectively, to deodorize the aquaculture chamber.

[0034] In one possible implementation, controlling the black soldier fly farming system to cycle between water supply mode and cleaning mode when the average insect density is less than a density threshold includes:

[0035] When the average insect density is less than the density threshold, obtain the ambient temperature in the breeding chamber and the water level in the water storage chamber.

[0036] When the ambient temperature in the breeding chamber is greater than or equal to the temperature threshold and the water level in the water storage tank is lower than the warning water level, the duty cycle of the water supply mode and the pipe cleaning mode is determined based on the average insect density and the ambient temperature to obtain the target duty cycle.

[0037] The switching action of the control valve is controlled according to the target duty cycle to cycle between water supply mode and cleaning mode.

[0038] In one possible implementation, determining the duty cycle of the water supply mode and the pipe cleaning mode based on the average insect density and the ambient temperature to obtain the target duty cycle includes:

[0039] A three-dimensional mapping model of the average insect density, ambient temperature and duty cycle was established. The three-dimensional mapping model was trained by machine learning algorithm based on historical aquaculture data.

[0040] The average insect density and ambient temperature are input into the three-dimensional mapping model, and the initial duty cycle of the corresponding water supply mode and cleaning mode is output.

[0041] The initial duty cycle is corrected based on the ambient temperature to obtain the target duty cycle. Specifically, when the ambient temperature is greater than or equal to the temperature threshold, the duty cycle of the cleaning mode during the cycle switching is increased; when the ambient temperature is less than the temperature threshold, the duty cycle of the water supply mode during the cycle switching is increased.

[0042] Thirdly, embodiments of this application also provide an electronic device, including a memory and a processor, wherein the memory is used to store program code; and the processor is used to call the program code to execute the method as described in the first aspect.

[0043] Unlike existing technologies, this application provides a black soldier fly larvae farming system, including a farming chamber, a water circulation module, a deodorization chamber, and a processor. The farming chamber contains a water supply sponge with an inclined water absorption area on its upper surface. The water circulation module includes a water supply pipe, a first return water pipe for cleaning mode, and a second return water pipe for water supply mode. The water supply pipe is connected to either the first or second return water pipe via a switching valve. The deodorization chamber contains a negative pressure device and a plasma deodorization module. Thus, this black soldier fly larvae farming system can operate in different modes according to the growth stage of the black soldier flies and real-time changes in the farming environment, and precisely control the operation of each module to effectively manage the black soldier fly farming process. In the water supply mode, by rationally adjusting the water supply path and volume of the water circulation module, the appropriate humidity of the water-supplying sponges can be ensured. In the cleaning mode, by switching the water circulation path, the circulating water flow can be used to clean the water storage pipes in the storage tank. In the deodorization mode, by activating the negative pressure device and the plasma deodorization module, odors generated during the breeding process can be dealt with in a timely manner. The comprehensive management and control method of this application helps to improve the efficiency and quality of black soldier fly farming, reduce breeding costs, and promote the sustainable development of the black soldier fly farming industry.

[0054] Black soldier flies, as a highly valuable resource insect, demonstrate enormous potential in the fields of ecological recycling and resource utilization. Their larvae can efficiently decompose and transform organic waste, such as kitchen waste and livestock manure, into high-quality insect protein and fat. This not only provides a green and environmentally friendly approach to solving the problem of organic waste treatment but also offers a new source of raw materials for industries such as feed and biofuels. Furthermore, the short growth cycle and high reproductive capacity of black soldier flies make large-scale farming a potentially lucrative economic and ecological endeavor, thus attracting increasing attention and research.

[0055] The management of the black soldier fly farming environment has been a long-standing obstacle to the industry's development. For example, the existing water supply system lacks water flow during the water supply process, and the excrement of black soldier flies can easily have an adverse effect on water quality, thereby affecting the growth and health of the black soldier flies.

[0056] It should be noted that black soldier fly larvae are primarily saprophytic, with a wide diet including livestock and poultry manure (such as pig, cow, and chicken manure), kitchen waste, decaying plant and animal matter, and agricultural byproducts (tofu residue, rice bran, wheat bran), etc. They can convert up to 100 times their own body weight in organic waste daily, and can efficiently decompose kitchen waste with 65% water content. Adult black soldier flies have smooth, glossy wings, and their mouthparts are degenerate; they do not feed on solid food, requiring only water or plant sap to survive.

[0057] like Figure 1-2 As shown in the embodiment of this application, a black soldier fly farming system is provided, including a farming chamber 100, a water circulation module 200, a deodorization chamber 300, and a processor 400.

[0058] The breeding chamber 100 contains food items for black soldier fly larvae, such as kitchen waste, piled on the floor. The chamber also houses a water-supply sponge 110. The upper surface of the sponge 110 has an inclined absorbent area, which better guides moisture distribution. This provides a suitable humidity environment for the black soldier fly larvae (the water from the sponge 110 evaporates into the environment, creating a humid environment) and also provides the adult black soldier fly with the water necessary to survive. Furthermore, the sponge 110 prevents the black soldier fly larvae from escaping.

[0059] For example, the water supply sponge 110 in the breeding chamber 100 is arranged in multiple layers, thereby providing a more sufficient and stable water absorption area for adult black soldier flies.

[0060] The water circulation module 200 includes a water storage tank 210, a water storage pipe 220 disposed in the water storage tank 210, a power unit 230 disposed on one side of the water storage tank 210, a water supply pipe 240 connected to the power unit 230, a first return water pipe 250, a second return water pipe 260, and a switching valve 270. The water supply pipe 240 is connected to the first return water pipe 250 or the second return water pipe 260 through the switching valve 270. The water supply sponge 110 is disposed in the second return water pipe 260 to absorb the water in the second return water pipe 260.

[0061] The water storage tank 210 serves as the water reserve center for the entire water cycle, capable of storing sufficient water to meet the water needs at different stages of black soldier fly farming. The power unit 230 is the power source for the water cycle and can employ a highly efficient and energy-saving water pump.

[0062] In one embodiment, the aquaculture chamber 100 and the deodorization chamber 300 are located on the ground, while the water storage chamber 210 is located underground. Thus, by placing the water storage chamber 210 underground, not only can natural rainfall be effectively utilized for water collection and replenishment, but the relatively stable temperature and humidity environment underground can also reduce water evaporation and temperature fluctuations, thereby ensuring water supply stability.

[0063] In one embodiment, the water storage pipe 220 installed inside the cabin is composed of multiple bamboo poles with a diameter of no more than 3 cm stacked one on top of the other. The natural hollow tubular structure of the bamboo pole is used to form a water storage channel. This design not only achieves efficient water storage, but also further reduces water evaporation loss, and has both environmental protection and energy-saving characteristics.

[0064] The switching valve 270 includes a drive motor (not shown in the figure) and a flap 271 that is connected to the drive motor. Under the drive of the drive motor, the flap 271 selectively blocks the first return water pipe 250 and the second return water pipe 260.

[0065] In one embodiment, a filter screen 280 is also provided inside the water storage tank 210. The filter screen 280 is located on one side of the power unit 230. The filter screen 280 can prevent excrement and other debris from entering the power unit 230 and cause the debris to settle in the water storage tank 210.

[0066] The deodorization chamber 300 is equipped with a negative pressure device 310 and a plasma deodorization module 320. The negative pressure device 310 is configured to drive the odorous gases in the breeding chamber 100 to the plasma deodorization module 320 for deodorization. The negative pressure device 310 can be a negative pressure fan, which generates a stable negative pressure environment to form a directional airflow channel, quickly and stably extracting irritating gases such as ammonia and hydrogen sulfide generated in the breeding chamber 100 and introducing them into the deodorization chamber. The plasma deodorization module 320 uses low-temperature plasma technology. When polluted gases pass through, high-energy electrons generated by high-voltage discharge in the module collide with gas molecules, decomposing odor molecules into harmless substances such as carbon dioxide and water. At the same time, active particles destroy the structure of bacteria, viruses, and other microorganisms, achieving the dual effects of deodorization and sterilization. The two work together to deeply purify the odors generated during the breeding process, ensuring fresh air in the breeding environment, reducing the impact of odors on the surrounding environment, and creating healthy space conditions for the growth of black soldier flies and the operators.

[0067] The processor 400 is configured to control the operating modes of the black soldier fly farming system, including one or more of the following modes: water supply mode, cleaning mode, and deodorization mode. Furthermore, the processor 400 is electrically connected to the power unit 230, the switching valve 270, the negative pressure device 310, and the plasma deodorization module 320.

[0068] It is understandable that during the black soldier fly breeding process, when adult black soldier flies absorb water on the water supply sponge 110, they are very likely to lay eggs on it, and the eggs or larvae tend to accumulate on the surface of the water supply sponge 110. This accumulation not only hinders the normal water supply function of the sponge, but also seriously affects the survival rate of larvae due to problems such as overcrowding and insufficient oxygen.

[0069] To address this issue, in one embodiment, a vibrator 120 is integrated inside or at the bottom of the water supply sponge 110. This vibrator 120 can be activated according to a preset program in the aquaculture system or real-time monitoring data. It generates mechanical force through high-frequency vibration, causing the larvae adhering to the water supply sponge 110 to separate from the sponge. During vibration, the larvae slide down the inclined water absorption area to the ground of the aquaculture chamber 100, thus entering a suitable growth environment. This effectively prevents excessive aggregation of larvae on the water supply sponge 110, ensuring a continuous water supply while creating a spacious and healthy growth space for the larvae, significantly improving the efficiency and quality of black soldier fly aquaculture.

[0070] The black soldier fly larvae farming system of this application provides three operating modes: 1) Water supply mode: By rationally adjusting the water supply path and volume of the water circulation module, the water supply sponges can be kept at a suitable humidity; 2) Cleaning mode: By switching the water circulation path, the circulating water flow can be used to clean the water storage pipes in the storage tank; 3) Deodorization mode: By activating the negative pressure device and plasma deodorization module, odors generated during the farming process can be dealt with in a timely manner. These three operating modes can be operated individually or in combination. When the three operating modes are operated in combination, the resulting integrated management and control method helps improve the efficiency and quality of black soldier fly farming, reduce farming costs, and promote the sustainable development of the black soldier fly farming industry.

[0071] This application also provides a method for managing black soldier fly larvae farming. The following description uses a black soldier fly larvae farming system as an example to illustrate this method. It should be noted that although the flowchart shows a logical order, in some cases, the steps shown or described may be executed in a different order. Please refer to the appendix. Figure 3 The method includes the following steps S100-S400:

[0072] Step S1 O0: Obtain image data of the water absorption area of ​​the water supply sponge to obtain multiple frames of the first target image;

[0073] Specifically, a high-definition industrial camera or infrared camera can be installed above or to the side of the water absorption area of ​​the water supply sponge 110 within the breeding chamber 100. Utilizing its high resolution and high frame rate, it can acquire real-time images of the water absorption area. Furthermore, the acquisition frequency (e.g., 5-10 frames per second) and acquisition duration can be flexibly set according to breeding needs, periodically acquiring image data within a preset time period (e.g., every 10 minutes as a monitoring cycle). The acquired images are automatically sorted according to timestamp order, forming a multi-frame image set arranged in a time sequence, i.e., the first target image. Simultaneously, to ensure the stability and accuracy of the image data, an image quality detection mechanism can be set up to automatically filter and re-acquire blurry or noisy images, ensuring the accuracy of subsequent insect density analysis.

[0074] Step S200: Input the multi-frame first target image into the insect density analysis model to obtain the average insect density within a preset time period;

[0075] Specifically, the insect density analysis model in this embodiment is constructed using a deep learning algorithm. The model is pre-trained with a large amount of labeled adult insect image data, enabling it to accurately identify the morphology, outline, and features of adult insects. When multiple frames of the first target image are input into the model, the model first uses image segmentation technology to perform pixel-level segmentation of the adult insects in each frame, distinguishing them from the background, water-supplying sponges, and other objects. Next, a target detection algorithm is used to count the number of adult insects in a single frame image, and combined with the image resolution and the actual shooting area, the adult insect density corresponding to that single frame image is calculated.

[0076] To obtain more accurate results, the system processes the adult insect density calculated from multiple frames within a preset time period. Specifically, the adult insect density of each frame is added together and then divided by the number of frames to obtain the average insect density within that preset time period.

[0077] In other embodiments, a data verification mechanism can be set in the insect density analysis model. If the adult insect density calculated from a certain frame deviates from the data of the preceding and following frames by more than a set threshold (such as 30%), the frame image will be automatically re-analyzed or marked as abnormal data to ensure that the final output average insect density is true and reliable, providing an accurate basis for the subsequent control of the breeding system.

[0078] Step S300: When the average density of insects is greater than or equal to the density threshold, control the black soldier fly breeding system to be in a continuous water supply mode, and control the vibrator to vibrate according to the average density of insects, wherein the vibrator is located inside the water supply sponge or at the bottom of the water supply sponge.

[0079] When the average density of adult insects within the preset time period calculated in step S200 reaches or exceeds the preset density threshold, it indicates that a large number of adult insects have gathered on the water supply sponge to absorb water. The excrement produced by these large numbers of adult insects during water absorption, such as nitrogenous compounds and uric acid, will rapidly dissolve in the water body of the water supply sponge, causing a sharp increase in indicators such as ammonia nitrogen content and chemical oxygen demand (COD), significantly deteriorating water quality in a short period. If not treated promptly, this will not only affect the normal water intake of the adult insects but may also breed harmful microorganisms, threatening the healthy growth of black soldier flies. At this time, the processor 400 immediately triggers the continuous water supply mode: by sending a control signal to the switching valve 270, it drives the flap to rotate, keeping the water supply pipe 240 and the second return water pipe 260 in a stable connected state. This ensures a stable and uninterrupted water supply process, effectively protecting the water quality of the water supply sponge and meeting the growth needs of the black soldier flies.

[0080] Since a large number of adult insects significantly increases the probability and quantity of egg-laying on the water supply sponge 110, to prevent excessive accumulation of eggs and larvae on the sponge, which would affect the sponge's water supply function and larval survival rate, the processor 400 simultaneously activates the vibrator 120 control program to vibrate the eggs or larvae to fall onto the floor of the rearing chamber, thereby providing a more suitable growth space for the larvae and ensuring the normal working efficiency of the water supply sponge. During vibration operation, the vibrator can be controlled according to the average insect density, such as adjusting the vibration amplitude and frequency based on the average insect density.

[0081] In one embodiment, controlling the black soldier fly farming system to be in a continuous water supply mode includes: controlling the flap of a switching valve to rotate so that the water supply pipe is connected to the second return water pipe; determining the operating power of the power unit based on the average density of the insects to obtain a first target power, wherein the average density of the insects is positively correlated with the first target power; and controlling the power unit to operate at the first target power to continuously supply water to the water supply sponges.

[0082] First, the processor 400 sends a rotation command to the drive motor of the switching valve 270. After receiving the command, the drive motor drives the flap connected to it to rotate precisely. The rotation angle of the flap is monitored in real time by an angle sensor. When the flap rotates to a preset angle, it blocks the first return water pipe 250, so that the water supply pipe 240 and the second return water pipe 260 are stably connected, thereby establishing a channel for water supply from the water storage tank 21O to the water supply sponge 11O.

[0083] Then, the first target power P1 is determined using the formula P = k × D (where P is the operating power of the power unit in watts; D is the average insect density in insects / square centimeter; and k is the proportionality coefficient). The calibration of the proportionality coefficient k is based on historical aquaculture data and experimental tests. Before the system is put into use, the water supply demand under different insect densities is simulated multiple times, and the operating power of the power unit is recorded when the water supply conditions are met. Data fitting methods such as the least squares method are used to calculate the most suitable k value for the current aquaculture system.

[0084] Finally, the processor 400 converts the calculated first target power into a control signal and transmits it to the power unit 230. The frequency converter built into the power unit 230 adjusts its output power in real time according to the received control signal, operating stably at the first target power. This continuously delivers water from the water storage tank 210 to the water supply sponge 110 through the water supply pipe 240 and the second return pipe 260, ensuring that the water supply sponge 110 always maintains sufficient and stable water content to meet the water absorption needs of high-density adult insects.

[0085] In one embodiment, controlling the vibrator to vibrate based on the average density of the insects includes:

[0086] The target egg production rate is obtained by estimating the egg production rate of black soldier flies based on the average density of the insects and the environmental parameters in the breeding chamber.

[0087] The vibration parameters of the vibrator are determined based on the target egg production rate to obtain the target vibration parameters, wherein the target vibration parameters include vibration amplitude and vibration frequency;

[0088] The vibrator is controlled to vibrate at the target vibration parameters so that the insect eggs generated in the water absorption area of ​​the water supply sponge are vibrated and dropped onto the ground of the breeding chamber.

[0089] First, the target egg production rate is calculated using an egg production prediction model. This model is based on a multiple linear regression algorithm, with the formula W = αD + βT + γH + δ (where W is the target egg production rate in eggs; D is the average insect density in eggs / cm²; T is the ambient temperature in the rearing chamber in °C; H is the ambient humidity in the rearing chamber in %; α, β, and γ are the weighting coefficients for the corresponding parameters, and δ is a constant). The weighting coefficients α, β, and γ, and the constant δ, are obtained through machine learning training on a large amount of historical rearing data. During training, actual egg production data under different insect densities, ambient temperatures, and humidity conditions are collected, and optimization algorithms such as gradient descent are used to continuously adjust the model parameters to minimize the mean square error between the model's predicted and actual values. Once the current average insect density D, ambient temperature T, and humidity H are obtained, they are substituted into the model formula to calculate the target egg production rate W.

[0090] Then, the target vibration parameters of the vibrator are determined based on the target egg-laying volume. To precisely control the vibration effect, this application embodiment establishes a vibration parameter-egg-laying volume mapping table, which was generated through extensive preliminary control experiments. In the experiments, different vibration amplitudes (range A) were set. min -A max (unit: millimeters) and vibration frequency (range: f) min -f max A vibration experiment was conducted on a water supply sponge containing different numbers of eggs or larvae (in Hertz) using various parameter combinations. The number and proportion of eggs that successfully fell to the floor of the rearing chamber under each parameter combination were recorded. Based on the experimental results, an interpolation algorithm was used to construct a functional relationship between the vibration amplitude A, the vibration frequency f, and the target egg production W: A = f A (W), f = f f (W). Once the target egg production W is obtained, substitute the values ​​into the above function to calculate the corresponding vibration amplitude A and vibration frequency f, thus obtaining the target vibration parameters.

[0091] Finally, the processor 400 converts the calculated target vibration parameters into control signals and sends them to the vibrator 120 inside or at the bottom of the water supply sponge. The controller built into the vibrator 120 precisely adjusts its vibration amplitude and frequency according to the received control signals to operate with the target vibration parameters. Through high-frequency and appropriately amplitude vibration, the water supply sponge 110 generates mechanical shaking, effectively vibrating and dislodging insect eggs or larvae attached to the water absorption area onto the floor of the breeding chamber, preventing the eggs from accumulating on the sponge and creating a favorable growth environment for the larvae.

[0092] Step S400: When the average density of insects is less than the density threshold, control the black soldier fly breeding system to switch between water supply mode and cleaning mode in a cyclical manner.

[0093] When the average adult insect density calculated in step S200 within a preset time period is less than a preset density threshold, it indicates that the number of adults gathered on the water supply sponge is small, and their excrement has a relatively small impact on the water quality of the sponge, and will not cause water quality deterioration in the short term. However, in order to maintain the long-term stable operation of the entire aquaculture system, it is necessary to ensure normal water supply while promptly cleaning the excrement and other debris accumulated in the water storage pipes of the storage tank to avoid pipe blockage affecting water circulation efficiency. Especially when the ambient temperature is high, the evaporation of water in the storage tank intensifies, and the water level is prone to drop. At this time, the upper water storage pipes may be empty but have residual excrement and other debris. After these debris dries and hardens, they can easily cause pipe blockage, seriously threatening the normal operation of the water circulation system.

[0094] In one embodiment, when the average insect density is less than a density threshold, the ambient temperature in the breeding chamber and the water level in the water storage chamber are acquired; when the ambient temperature in the breeding chamber is greater than or equal to a temperature threshold and the water level in the water storage chamber is lower than a warning level, the duty cycle of the water supply mode and the pipe cleaning mode is determined based on the average insect density and the ambient temperature to obtain a target duty cycle; the switching action of the switching valve is controlled according to the target duty cycle to perform cyclic switching between the water supply mode and the cleaning mode.

[0095] First, when the average insect density is less than the density threshold, the processor 400 simultaneously acquires the ambient temperature in the breeding chamber and the water level in the water storage tank. When the ambient temperature in the breeding chamber is greater than or equal to the temperature threshold, and the water level in the water storage tank is lower than the warning level, a cyclical switching control process between water supply mode and cleaning mode is initiated.

[0096] Then, the target duty cycle for the water supply mode and the cleaning mode is determined based on the average insect density and the ambient temperature.

[0097] Finally, the switching valve is controlled according to the target duty cycle to cycle between water supply mode and cleaning mode. The processor 400 converts the target duty cycle into a time control signal, setting the single run duration of water supply mode and cleaning mode. During the water supply mode, the processor 400 sends a control signal to the switching valve 270, driving the flap to rotate and connect the water supply pipe 240 with the second return water pipe 260. At the same time, the operating power of the power unit 230 is adjusted in real time according to the water level in the storage tank to ensure stable water supply from the water sponge 110. When the water supply mode run duration reaches the set value, the processor 400 controls the switching valve 270 again to connect the water supply pipe 240 with the first return water pipe 250, entering the cleaning mode. At this time, the power unit 230 first operates at a lower power, and then increases the power to form a pulsed strong water flow to flush the water storage pipe, thereby carrying out the debris from the water storage pipe and allowing it to settle in the water storage tank. After the cleaning mode runs out, the system automatically switches back to the water supply mode, and so on, ensuring the stable operation of the aquaculture system.

[0098] In one embodiment, determining the duty cycle of the water supply mode and the pipe cleaning mode based on the average insect density and the ambient temperature to obtain the target duty cycle includes:

[0099] A three-dimensional mapping model of the average insect density, ambient temperature and duty cycle was established. The three-dimensional mapping model was trained by machine learning algorithm based on historical aquaculture data.

[0100] The average insect density and ambient temperature are input into the three-dimensional mapping model, and the initial duty cycle of the corresponding water supply mode and cleaning mode is output.

[0101] The initial duty cycle is corrected based on the ambient temperature to obtain the target duty cycle. Specifically, when the ambient temperature is greater than or equal to the temperature threshold, the duty cycle of the cleaning mode during the cycle switching is increased; when the ambient temperature is less than the temperature threshold, the duty cycle of the water supply mode during the cycle switching is increased.

[0102] Specifically, firstly, a large amount of historical aquaculture data was collected, covering the actual duty cycles of water supply and cleaning modes under different average insect densities (ranging from low to high) and ambient temperatures (covering possible temperature ranges during the aquaculture process), as well as corresponding aquaculture performance indicators (such as black soldier fly growth rate, survival rate, and water quality changes). A neural network algorithm from deep learning, such as a multilayer perceptron (MLP), was used to construct a three-dimensional mapping model of average insect density, ambient temperature, and duty cycle. The historical data was divided into training, validation, and test sets. During training, average insect density and ambient temperature were used as input features, and the actual duty cycle was used as the output label. The weights and bias parameters of the neural network were continuously adjusted using a backpropagation algorithm to minimize the mean squared error (MSE) between the model's predicted duty cycle and the actual duty cycle. Model performance was evaluated in real-time on the validation set to avoid overfitting. Once the model reached a preset accuracy standard on the test set (e.g., MSE less than 0.05), model training was completed, resulting in a stable and reliable three-dimensional mapping model.

[0103] Then, the real-time average insect density and ambient temperature are used as input parameters and fed into the trained three-dimensional mapping model. The model, through its internal neural network, calculates and outputs the initial duty cycles G1 and G2 for the corresponding water supply and cleaning modes, respectively, satisfying G1 + G2 = 1. These initial duty cycles are preliminary results derived from historical aquaculture data patterns, providing a foundation for subsequent optimization and adjustments.

[0104] Finally, the initial duty cycle is corrected based on the ambient temperature. When the ambient temperature T is greater than or equal to the temperature threshold, the risk of water level drop in the storage tank increases. In this case, a temperature influence coefficient α (α > 1) is introduced, and the duty cycle of the cleaning mode is increased using the formula G2′ = α × G2. Simultaneously, G1′ = 1 - G2′ is used to adjust the duty cycle of the water supply mode accordingly, where G1′ and G2′ are the corrected duty cycles for the water supply mode and cleaning mode, respectively. When the ambient temperature T is less than the temperature threshold, the risk of water level drop in the storage tank is not significant. In this case, a temperature influence coefficient β (0 < β < 1) is introduced. The specific correction calculation process is similar to the above and will not be repeated here. α and β can be set according to the actual situation.

[0105] like Figure 4 As shown, in another embodiment, the black soldier fly farming management method of this application further includes:

[0106] Step S500: Obtain image data of the ground of the aquaculture chamber to obtain multiple frames of the second target image;

[0107] Step S600: Input multiple frames of the second target image into the larval density analysis model to obtain the average larval density within a preset time period;

[0108] Step S700: Determine the operating power of the negative pressure device and the plasma deodorization module based on the average larval density to obtain the second operating power and the third operating power;

[0109] Step S 800: Control the negative pressure device and the plasma deodorization module to operate at the second operating power and the third operating power respectively to deodorize the aquaculture chamber.

[0110] It should be noted that there is a certain correlation between the number of larvae and the generation of odor. The more larvae there are, the greater the amount of rotten food they decompose, resulting in a stronger and more persistent odor. Therefore, in this embodiment, the negative pressure device and plasma deodorization module are adaptively controlled based on the average larval density to deodorize the breeding chamber more accurately and efficiently.

[0111] Specifically, in this embodiment, a high-definition wide-angle camera can be installed at a suitable location above the floor of the breeding chamber. This camera has automatic focusing and low-light compensation functions, and can adapt to the complex lighting environment inside the breeding chamber. By setting the image acquisition frequency (e.g., 3-5 frames per second) and acquisition duration (e.g., every 15 minutes as an acquisition cycle), image data of the breeding chamber floor is acquired periodically. To ensure image quality, the system is equipped with an image preprocessing module, which uses a median filtering algorithm to remove image noise and histogram equalization technology to enhance image contrast. The processed multi-frame images are arranged in chronological order to form multiple frames of second target images, providing a clear and accurate data foundation for subsequent larval density analysis.

[0112] The larval density analysis model is built on a convolutional neural network (CNN) architecture and is pre-trained using a large amount of image data labeled with larval locations and numbers. When multiple frames of the second target image are input into the model, the model first extracts larval features from the images through convolutional and pooling layers, then uses a region proposal network (RPN) to generate candidate regions that may contain larvae, and finally uses classification and regression layers to accurately identify the larvae and count their numbers. The larval density (number of larvae / corresponding actual area of ​​the image) is calculated for each frame. The larval densities of all frames within a preset time period are summed and divided by the number of image frames to obtain the average larval density for that time period.

[0113] This application pre-establishes a database mapping the relationship between larval density and the operating power of deodorization equipment. This database is constructed based on a large amount of experimental data, recording the operating power required by the negative pressure device and the plasma deodorization module to achieve the ideal deodorization effect under different larval densities. After obtaining the average larval density, the second operating power P2 corresponding to the negative pressure device and the third operating power P3 corresponding to the plasma deodorization module are determined through database query or interpolation calculation. The processor converts the calculated second and third operating powers into control signals and sends them to the negative pressure device and the plasma deodorization module, respectively. The negative pressure device has a built-in frequency converter that adjusts the motor speed in real time according to the received signal, so that the negative pressure device operates stably at the second operating power, generating a suitable intensity of negative pressure to quickly extract odor from the breeding chamber and transport it to the deodorization chamber. The plasma deodorization module, through a power adjustment module, precisely adjusts the discharge voltage and current according to the control signal to operate at the third operating power, generating a sufficient amount of high-energy active particles to efficiently decompose odor molecules and achieve deep deodorization of the breeding chamber.

[0114] Based on this, the black soldier fly farming system of this application can operate in different modes according to the growth stage of the black soldier flies and the real-time changes in the farming environment, and precisely control the operation of each module to effectively manage the farming process. In the water supply mode, by reasonably adjusting the water supply path and volume of the water circulation module, the water supply sponges can be kept at an appropriate humidity. In the cleaning mode, by switching the water circulation path, the circulating water flow can be used to clean the water storage pipes in the storage tank. In the deodorization mode, by activating the negative pressure device and the plasma deodorization module, the odor generated during the farming process can be dealt with in a timely manner. The comprehensive management and control method of this application helps to improve the efficiency and quality of black soldier fly farming, reduce farming costs, and promote the sustainable development of the black soldier fly farming industry.
