Description

Technical Field

[0001] This invention relates to the field of insect farming technology, specifically to a system and method for the cyclical farming of horsefly larvae and adults. Background Technology

[0002] As an important resource insect, the military fly is rapidly expanding its industrialized breeding scale due to its huge potential in the conversion of organic waste and the provision of high-quality protein feed. However, under the intensive and high-density breeding model, existing technologies face several bottlenecks.

[0003] Warrior soldier fly larvae generate a significant amount of metabolic heat during their growth. If this heat cannot be dissipated effectively and promptly, it can lead to excessively high temperatures in the feed bed, inhibiting normal larval development and potentially causing population mortality. Currently used methods such as ventilation and cooling have low control precision and high energy consumption. Furthermore, this valuable biological heat energy is directly released into the environment as waste heat, resulting in substantial energy waste. At the same time, to maintain the vitality and reproductive efficiency of adult larvae, the rearing environment requires additional energy for heating and lighting, creating an energy disconnect between passive heat dissipation on one end and active energy consumption on the other.

[0004] Existing technologies manage the two key life stages of larvae and adults in a fragmented manner. Environmental control in adult areas (such as lighting) is usually based on fixed schedules or experience-based settings, and cannot dynamically respond according to the actual development process and vitality of the larval population. This information lag leads to blind optimization of the adult breeding environment, making it difficult to proactively match the best mating and breeding conditions during the critical window period when larvae are about to pupate in large numbers and adults are about to emerge in large numbers, thus limiting the overall output efficiency of the entire breeding system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a system and method for the cyclical rearing of horsefly larvae and adults, which solves the energy waste problem caused by the passive loss of metabolic heat in larvae and the independent energy consumption for heating in adult areas, as well as the problem of delayed response in regulating the reproductive environment of adults due to the lack of cross-stage state perception.

[0021] In the specific technical solution, the thermoelectric energy coupling and microenvironment precise control module includes:

[0022] A semiconductor thermoelectric element array, the cold end of which faces the interior of the larval rearing and energy capture module; and a heat exchange interface, the hot end of which is connected to the heat exchange fluid circulation pipeline.

[0023] In a specific technical solution, the adult insect reproduction module also includes a biological pheromone slow-release device, which includes a temperature-controlled evaporation unit connected to the heat exchange fluid circulation pipeline to control the evaporation rate of the pheromone using the heat transported by the heat exchange fluid circulation pipeline.

[0024] A second aspect of the present invention provides a method for the cyclical rearing of horsefly larvae and adults, comprising the following steps:

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example:

[0042] Please see the appendix Figure 1 -Appendix Figure 6 This invention provides a system for the cyclical rearing of horsefly larvae and adults, comprising:

[0043] The larval rearing and energy capture module 10 is a physical unit used to house the horsefly larvae and their feed, and is the main site for larval growth and metabolic heat production.

[0044] In this embodiment, the main structure of the larval rearing and energy capture module 10 is an open box or a box with a removable cover. The box is made of engineering plastics with chemical stability and structural strength, such as food-grade polypropylene or high-density polyethylene. Both its inner and outer surfaces are made smooth to facilitate thorough cleaning of the module and material transfer.

[0045] The larval rearing and energy capture module 10 is designed as a standardized modular unit with uniform external dimensions and interfaces to facilitate stacking, array deployment, and automated handling within the rearing system. Its internal volume is set according to the preset feed input and larval rearing density.

[0046] To achieve automatic separation of larvae and feed, the larvae rearing and energy capture module 10 has a feed bed area at its bottom, and an inclined climbing ramp is provided on one or more sides of the area. The slope of the climbing ramp is set within the climbing ability range of the larvae in the prepupal stage, and its top is connected to the collection channel to guide the mature larvae to migrate to the collection system outside the module.

[0047] The key structure of the larval rearing and energy capture module 10 lies in its integration with the thermoelectric energy coupling and microenvironment precision control module 11. The bottom or side wall of the larval rearing and energy capture module 10 is provided with one or more flat mounting bases. These mounting bases are used to make surface contact with the cooling end of the thermoelectric energy coupling and microenvironment precision control module 11, and a low thermal resistance heat conduction path is ensured between the two through a heat-conducting medium or fasteners. This structure allows the cooling capacity of the module 11 to directly act on the core area of ​​the feed bed.

[0048] The thermoelectric energy coupling and microenvironment precision control module 11 is the core functional unit that performs local cooling, captures metabolic heat, and transmits heat information.

[0049] In this embodiment, the thermoelectric energy coupling and microenvironment precise control module 11 includes a semiconductor thermoelectric element array 111, a cold-end heat-conducting plate 112, a hot-end liquid-cooled heat sink 113, and a temperature sensor 114. The semiconductor thermoelectric element array 111 is composed of multiple Peltier effect thermoelectric elements. These elements are connected in series or in parallel in the circuit according to the required voltage and current characteristics, and are arranged in parallel in the thermal field to form a cooling surface with a preset total cooling power.

[0050] The cold end heat conduction plate 112 is made of a material with high thermal conductivity. One surface of the plate is in close contact with all the cold ends of the semiconductor thermoelectric element array 111 to collect the total cooling capacity generated by the array. The other surface of the cold end heat conduction plate 112 is in surface contact with the mounting base of the larval rearing and energy capture module 10. By filling with thermally conductive silicone grease and fixing with fasteners, it is ensured that the cooling capacity can be transferred to the feed bed with low thermal resistance.

[0051] The hot-end liquid-cooled heat sink 113 is also made of a material with high thermal conductivity. It has a microchannel structure inside to increase the contact area between the heat-carrying fluid and the inner wall of the heat sink. One surface of the hot-end liquid-cooled heat sink 113 is in close contact with all the hot ends of the semiconductor thermoelectric element array 111 to absorb and remove the heat generated when the thermoelectric element is working and the heat transferred from the cold end. The hot-end liquid-cooled heat sink 113 is provided with two fluid interfaces, which are connected to the heat exchange fluid circulation pipeline 30 as the inlet and outlet, respectively.

[0052] Temperature sensor 114, such as an NTC thermistor or a DS18B20 digital temperature sensor encapsulated in a waterproof probe, is deployed inside the feed bed of the larval rearing and energy capture module 10 for real-time monitoring of local temperature. And transmit its reading to the central control system 40. The central control system 40 according to With preset temperature threshold The comparison results are used to control the DC power supplied to the semiconductor thermoelectric element array 111 through the PWM drive circuit, thereby achieving precise adjustment of the cooling capacity.

[0053] To calculate the instantaneous heat flux captured by this module An inlet temperature sensor and an outlet temperature sensor are respectively installed at the fluid inlet and outlet of the hot-end liquid-cooled heat sink 113, and are used in conjunction with a flow meter. The central control system 40 reads the temperature difference between the inlet and outlet, the real-time flow rate of the fluid, and the specific heat capacity of the fluid, and calculates the total heat carried away by the heat-carrying fluid according to the thermodynamic formula. Then, it subtracts the heat generated by the electrical power consumed by the semiconductor thermoelectric element array 111 during its operation, thereby accurately obtaining the instantaneous heat flux transferred from the feed bed. .

[0054] The adult reproduction module 20 provides a controllable physical space for the mating and oviposition activities of adults.

[0055] In this embodiment, the main body of the adult insect breeding module 20 is a closed cage supported by a metal or composite material frame. Its walls are made of light-transmitting nylon or stainless steel mesh with a preset mesh size to ensure internal air circulation and prevent adult insects from escaping. The bottom of the adult insect breeding module 20 is provided with a tray for collecting waste and cleaning.

[0056] In order to receive the heat delivered by the heat exchange fluid circulation pipe 30, heat dissipation pipes are deployed on the bottom or side wall of the adult insect breeding module 20. The heat dissipation pipes are connected to the heat exchange fluid circulation pipe 30. When the heat-carrying fluid flows through the pipes, it releases heat into the internal space of the module through thermal radiation and natural convection to maintain the reference temperature required for adult insect activity. The layout of the heat dissipation pipes is set to create an environment with a small temperature gradient inside the module so that the adult insects can choose the appropriate temperature area autonomously.

[0057] The adult breeding module 20 has internal structures for guiding adult behavior. For example, the internal space of the module has sufficient height to meet the mating behavior of adults. The walls or interior of the module are provided with three-dimensional structures for adults to inhabit, such as vertically suspended mesh or grid panels.

[0058] In this embodiment, the adult reproduction module 20 also includes a biological pheromone slow-release device 22, which is used to release aggregation pheromones or oviposition attractants. The biological pheromone slow-release device 22 includes a shell for containing the pheromone carrier and a miniature heat exchanger connected to the heat exchange fluid circulation pipeline 30. By controlling the flow rate of the heat-carrying fluid flowing through the miniature heat exchanger, the temperature of the pheromone carrier can be precisely adjusted, thereby controlling the evaporation rate of the pheromone.

[0059] To facilitate the collection of insect eggs, the adult breeding module 20 is equipped with a dedicated oviposition device. This device consists of multiple stacked oviposition blocks with a slatted structure, such as wooden or plastic slats. A container containing an oviposition attractant is placed beneath the oviposition device. Female adults are lured here and lay their eggs in the slats of the oviposition blocks. The oviposition blocks are designed to be periodically removed to achieve mass collection of the eggs.

[0060] The natural rhythm dynamic lighting module 21 is an execution unit used to generate a controllable lighting environment within the adult insect breeding module 20. It receives and executes instructions from the central control system 40.

[0061] In this embodiment, the natural rhythm dynamic lighting module 21 includes an LED array panel 211 and a multi-channel LED driver 212. The LED array panel 211 is mounted on the top of the adult insect breeding module 20, and a light diffusion plate is provided below it to ensure uniform distribution of light in the internal space of the module.

[0062] At least two types of LED chips are integrated on the LED array panel 211:

[0063] The first type is a full-spectrum white LED chip that covers the main wavelengths of visible light, used to provide basic illuminance and simulate sunlight color temperature;

[0064] The second type is a monochromatic LED chip with a specific wavelength, such as a blue LED with a peak wavelength around 450nm and a red LED with a peak wavelength around 660nm, which is used to adjust the spectral composition of the light.

[0065] The multi-channel LED driver 212 is the control core of the natural rhythm dynamic lighting module 21. Its input is electrically connected to the control signal output port of the central control system 40, and its output is connected to the circuits of different types of LED chips on the LED array panel 211. The central control system 40 sends multiple independent pulse width modulation control signals to the multi-channel LED driver 212 to control the driving current of the full-spectrum white LED, blue LED and red LED respectively, thereby realizing independent and dynamic adjustment of total illuminance, color temperature and specific spectral ratio.

[0066] The central control system 40 internally stores the reference lighting program. The program defines the illumination variation curve for a standard day, including the total duration of illumination, and simulates the changes in light intensity and spectrum during sunrise, noon, and sunset. The central control system 40 uses the dynamic adjustment amount calculated by the feedforward control model. With reference lighting procedure The layers are then overlaid to generate the final execution lighting procedure. The final program is converted into a real-time PWM duty cycle sequence corresponding to each LED channel and sent to the multi-channel LED driver 212, thereby realizing a dynamic lighting environment that matches the growth rhythm of the larval population within the adult reproduction module 20.

[0067] The heat exchange fluid circulation pipeline 30 is a closed loop system used to transport heat-carrying fluid between the thermoelectric energy coupling and microenvironment precision control module 11 and the adult insect reproduction module 20.

[0068] In this embodiment, the heat exchange fluid circulation pipeline 30 is made of polyacrylonitrile pipe or stainless steel corrugated pipe, which are corrosion-resistant and temperature-resistant. The outer wall of the pipeline is wrapped with a closed-cell rubber and plastic insulation material to reduce the heat loss of the heat-carrying fluid to the surrounding environment during transportation and to ensure the efficiency of heat transportation from the capture end to the utilization end.

[0069] The heat transfer fluid circulating within the pipeline system is deionized water, to which a specific proportion of rust inhibitors and scale inhibitors are added to prevent corrosion or blockage of the inner walls of the pipeline and the interfaces of the heat exchanger. This fluid medium has a high specific heat capacity and moderate viscosity, making it suitable for long-distance heat transfer.

[0070] A circulating pump 31 is installed in series in the heat exchange fluid circulation pipeline 30. The circulating pump 31 is a centrifugal pump with variable frequency control. Its power supply and control terminal are electrically connected to the central control system 40. The central control system 40 changes the speed of the circulating pump 31 by adjusting the output frequency of the frequency converter according to the total heat load demand of the system, thereby accurately controlling the mass flow rate of the heat transfer fluid in the entire pipeline system.

[0071] When the system is equipped with multiple larval breeding and energy capture modules 10, the heat exchange fluid circulation pipeline 30 is designed as a parallel topology. This structure includes a main pipeline and multiple branch pipelines. The main pipeline is responsible for connecting the adult breeding module 20, while each branch pipeline is respectively connected to the thermoelectric energy coupling and microenvironment precision control module 11. This parallel structure ensures that the hot end of each module 11 can obtain a uniform fluid flow, which is beneficial to the overall heat balance and control of the system.

[0072] The central control system 40 is the core of the entire system's control and decision-making, responsible for data acquisition, status assessment, model calculation, and command issuance.

[0073] In this embodiment, the hardware of the central control system 40 includes a microcontroller unit 41, a storage unit 42, a data acquisition interface 43, and a control output interface 44. The microcontroller unit 41 acts as the system's processor, responsible for executing the program code and algorithms stored in the storage unit 42. The storage unit 42 is used to store the operating system, control program, and preset parameters (such as temperature thresholds). Time delay constant (and historical data collected during operation).

[0074] The data acquisition interface 43 includes multiple analog-to-digital conversion channels and digital input or output ports, which are used to connect various sensors in the system. For example, it can read analog voltage signals from temperature sensor 114 through analog-to-digital conversion channels or receive readings from digital temperature sensors through digital communication buses, and receive pulse signals from flow meters.

[0075] The control output interface 44 includes multiple pulse width modulation generators and frequency control output ports. It is used to send control commands to the system's execution components, for example, outputting pulse width modulation generator signals to the drive circuit of the thermoelectric energy coupling and microenvironment precision control module 11 to adjust cooling power, outputting another set of multi-channel pulse width modulation generator signals to the multi-channel LED driver 212 of the natural rhythm dynamic lighting module 21 to adjust lighting parameters, and outputting frequency signals to the frequency converter of the circulating pump 31 to adjust fluid flow.

[0076] The central control system 40 performs the following functions at the software level:

[0077] First, the microcontroller unit 41 periodically collects the temperature within each larvae rearing and energy capture module 10, as well as the inlet and outlet temperatures and fluid flow rates of the corresponding branches in the heat exchange fluid circulation pipeline 30, through the data acquisition interface 43. Based on this data, the system calculates the instantaneous heat flux captured by each module. And according to the formula Calculate the total heat flux of the entire larval population. The result, along with the timestamp, is stored in storage unit 42.

[0078] Secondly, the microcontroller unit 41 retrieves historical data from the storage unit 42 and analyzes the total heat flux. Perform time-difference operations to calculate its rate of change. The system analyzes amplitude and The sign and magnitude of the value are used to assess the current macroscopic growth stage of the larval population, such as the rapid growth phase, plateau phase, or decline phase.

[0079] Then, the system executes the feedforward control model, the core calculation formula of which is: In this embodiment, the function It is implemented as a two-dimensional lookup table stored in storage unit 42, which uses the historical total heat flux as the reference. and historical heat flux change rate The discretized numerical value is used as the input index, and its output value is a preset dynamic adjustment amount. The adjustment amount This is a data structure containing multiple parameters, such as the total illumination intensity adjustment factor, the photoperiod duration adjustment value, and the adjustment value for the proportion of a specific spectrum (such as blue light).

[0080] Finally, the microcontroller unit 41 will calculate the dynamic adjustment amount. The reference lighting program is applied to the storage unit 42. This generates the final execution lighting program. Subsequently, the system will execute the program. The analysis is based on the real-time pulse width modulation generator duty cycle sequence of each LED channel in the simulated natural rhythm dynamic lighting module 21, and is sent out through the control output interface 44 to complete the forward-looking regulation of the lighting environment in the adult insect breeding area.

[0081] Please see the appendix Figure 6 A method for the cyclical rearing of horsefly larvae and adults includes the following steps:

[0082] S100: Real-time monitoring of the temperature of the larval rearing environment, while maintaining the baseline heating and lighting program within the adult breeding module.

[0083] S200: When the temperature of the larval breeding environment exceeds the preset threshold, the thermoelectric energy coupling and microenvironment precision control module is activated to cool down the environment. The metabolic heat of the larvae captured in this process is then transported to the adult breeding module for heating through the heat exchange fluid circulation pipeline.

[0084] S300. While executing step S200, the central control system collects and calculates the total heat flux captured by the thermoelectric energy coupling and microenvironment precision control module to obtain a heat signal characterizing the macroscopic metabolic level of the larval population, and stores the signal and the corresponding timestamp into the storage unit.

[0085] S400 and the central control system, based on historical thermal signal data in the storage unit, execute a preset feedforward control model to calculate the dynamic adjustment amount of the light environment for the adult insect breeding module.

[0086] The S500 central control system applies the calculated dynamic adjustment amount to the reference lighting program, generates the final execution lighting program, and sends control commands to the natural rhythm dynamic lighting module to execute the program.

[0087] S600, continuously cyclically execute steps S100 to S500 to achieve continuous and automated control of the breeding process by the system.

[0088] The specific execution process is as follows:

[0089] After system initialization, the central control system 40 continuously monitors the local temperature of the feed bed through temperature sensors 114 deployed in each larval rearing and energy capture module 10. Meanwhile, the central control system 40 controls the natural rhythm dynamic lighting module 21 to use a preset reference lighting program. Run, providing basic lighting for adult insect reproduction module 20.

[0090] When the temperature within any larval rearing and energy capture module 10 Exceeding the preset startup threshold At the same time, the central control system 40 sends a pulse width modulation generator signal to the drive circuit of the corresponding thermoelectric energy coupling and microenvironment precision control module 11 through the control output interface 44 to start its cooling function. At the same time, the central control system 40 starts the circulation pump 31 in the heat exchange fluid circulation pipeline 30.

[0091] The cold end of the thermoelectric energy coupling and microenvironment precision control module 11 cools the feed bed, and the heat absorbed by its hot end is carried away by the heat-carrying fluid in the hot end liquid cooling heat sink 113. The heat-carrying fluid is transported to the heat dissipation pipe in the adult insect breeding module 20 through the heat exchange fluid circulation pipeline 30, and provides heat to the adult insect breeding area through heat exchange.

[0092] During the aforementioned energy transfer process, the central control system 40 synchronously collects and calculates the instantaneous heat flux through the data acquisition interface 43. The required sensor data were collected, and the total heat flux of the population was calculated. This data is recorded in real time.

[0093] The microcontroller unit 41 of the central control system 40 periodically executes the feedforward control model, which extracts the current time from the storage unit 42. Previous Total population heat flux at time and its rate of change Using these two values ​​as input, the model outputs the dynamic adjustment amount of illumination through table lookup or function calculation. .

[0094] The central control system 40 will dynamically adjust this amount. With reference lighting procedure Algorithm overlay is performed to generate a new, dynamically modified execution lighting program. The program is parsed into a specific pulse width modulation generator control sequence and sent to the multi-channel LED driver 212 of the natural rhythm dynamic lighting module 21 through the control output interface 44, thereby adjusting the total light intensity, photoperiod or spectral composition in the adult breeding area. The whole process is automatic and continuous, forming a closed loop based on the feedforward regulation of the adult breeding environment according to the larval metabolic information.
