Description

Technical Field

[0001] This application relates to the technical field of insect breeding environment adjustment, and particularly to a method and system for controlling the breeding environment of insect larvae. Background Art

[0002] Insect larvae are a stage in the life cycle of insects, usually occurring after egg hatching and before adulthood. The advantages of three-dimensional breeding of insect larvae are high space utilization rate, more precise environmental control, more effective disease control, etc. Heat, odor, and water vapor evaporated from materials generated during the growth of insect larvae and their synergistic process with microorganisms will randomly spill over the entire breeding workshop. At this time, due to the great difficulty in environmental control, the breeding cost of insect larvae is greatly increased. Therefore, it is necessary to propose a method and system for controlling the breeding environment of insect larvae to address the defect of excessively high environmental adjustment cost in the traditional process of breeding insect larvae. Summary of the Invention

[0003] Based on this, it is necessary to propose a method and system for controlling the breeding environment of insect larvae to address the defect of excessively high environmental adjustment cost in the traditional process of breeding insect larvae.

[0005] Determine the growth time of insect larvae;

[0006] Divide the growth time of insect larvae in days;

[0007] Obtain the number of divisions;

[0008] Based on the number of divisions, divide the corresponding number of breeding areas;

[0018] This application relates to a method and system for controlling the breeding environment of insect larvae. By determining that the growth time of insect larvae can be in days, the growth time of insect larvae is segmented to determine the number of breeding areas and the arrangement shape of the breeding areas. The process is simple, the control is convenient, and it is easy to automatically adjust the breeding environment of insect larvae. According to the arrangement shape of the breeding areas, the air supply program is executed at one end of the same breeding area, and the exhaust program is executed at the other end of the same breeding area. Using the breeding workshop as the air duct reduces the air supply and exhaust pipes and valves in the workshop, reducing equipment investment. Under the same environmental control conditions, due to the smaller cross-sectional area of the channel, a faster wind speed can be achieved with a smaller air change rate, which is beneficial to heat dissipation and water evaporation, and greatly reduces the air treatment cost. Due to the reverse air supply, the warm air flow generated in the middle area of the breeding can heat the low-temperature materials in the breeding area at the head end, eliminating the need to set up a heating device.

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] The present application provides a method for controlling the breeding environment of insect larvae.

[0027] As Figure 1 shown, in an embodiment of the present application, a method for controlling the breeding environment of insect larvae includes:

[0028] S100, determining the growth time of insect larvae.

[0029] S200, dividing the growth time of insect larvae in days.

[0030] S300, obtaining the number of divisions.

[0031] S400, based on the number of divisions, dividing the corresponding number of breeding areas.

[0032] S500, using the number of breeding areas, selecting a linear, circular or loop-shaped arrangement of breeding areas.

[0033] S600, according to the arrangement shape of the breeding areas, performing an air supply program in the terminal breeding area.

[0034] S700, performing an exhaust program in the first breeding area.

[0035] This embodiment relates to a method for controlling the breeding environment of insect larvae. By determining the growth time of insect larvae, the growth time of insect larvae can be divided in days, and the number of breeding areas and the arrangement shape of breeding areas can be determined. The process is simple, the control is convenient, and it is easy to realize the automatic adjustment of the breeding environment of insect larvae. According to the arrangement shape of the breeding areas, an air supply program is performed at one end of the same breeding area, and an exhaust program is performed at the other end of the same breeding area. Using the breeding workshop as the air duct reduces the supply and exhaust air pipes and valves in the workshop, and reduces the equipment investment. Under the same environmental control conditions, due to the smaller cross-sectional area of the channel, a faster air speed can be achieved with a smaller air change rate, which is beneficial to heat dissipation and water evaporation, and greatly reduces the air treatment cost. Due to the reverse air supply, the warm air flow generated in the middle area of the breeding can heat the low-temperature materials in the first breeding area, and there is no need to set up a heating device.

[0036] In an embodiment of the present application, S400 includes:

[0037] S410, defining the first breeding area as the breeding area for insect larvae with a growth time of the first day.

[0038] S420, defining the terminal breeding area as the breeding area for insect larvae with a growth time of the last day.

[0039] S430, defining the same breeding area as the breeding area for insect larvae with the same growth time.

[0040] This embodiment relates to a method for dividing a breeding area. The breeding area is divided into several breeding zones according to the breeding days, and the larvae in each breeding zone are in the same growth stage. A trolley loaded with materials and larvae enters the first breeding zone from the entrance. On the second day, the trolley in the first breeding zone enters the second breeding zone, and a trolley loaded with new materials and larvae enters the first breeding zone. And so on, every day, the trolley moves backward to the next breeding zone along the channel direction. After a breeding cycle, it moves to the nth breeding zone and exits the breeding area from the exit. The trolley loaded with materials and larvae in the nth breeding zone enters the next screening process.

[0041] In an embodiment of the present application, after S500, it includes:

[0042] S511, detecting the temperature of the breeding zone at the end.

[0043] S512, based on the temperature of the breeding zone at the end, determining whether the temperature of the breeding zone at the end is greater than or equal to 20 degrees Celsius and less than or equal to 30 degrees Celsius.

[0044] S513, if the temperature of the breeding zone at the end is greater than or equal to 20 degrees Celsius and less than or equal to 30 degrees Celsius, then execute the first air supply program of the air supply program.

[0045] Specifically, the first air supply program of the air supply program can be constant temperature, filtration, and dehumidification.

[0046] S514, if the temperature of the breeding zone at the end is less than 20 degrees Celsius, then execute the second air supply program of the air supply program.

[0047] Specifically, the second air supply program of the air supply program can be filtration, heating, and dehumidification.

[0048] S515, if the temperature of the breeding zone at the end is greater than 30 degrees Celsius, then execute the third air supply program of the air supply program.

[0049] Specifically, the third air supply program of the air supply program can be filtration, cooling, and dehumidification.

[0050] This embodiment relates to an air supply program. The air supply program adjusts the outside air into clean air with a temperature of 20 degrees Celsius to 30 degrees Celsius and a relative humidity of 30% to 60% through equipment such as filtration, heating, cooling, and dehumidification, and sends it into the breeding room from the air inlet. It flows in the opposite direction of the trolley operation to the entrance of the breeding room and enters the waste gas treatment equipment for treatment from the exhaust outlet.

[0051] In an embodiment of the present application, after S500, it further includes:

[0052] S521, detecting the relative humidity of the breeding zone at the end.

[0053] S522. Determine whether the relative humidity in the breeding area at the end is greater than or equal to 30% and less than or equal to 60% based on the relative humidity in the breeding area at the end.

[0054] S523. If the relative humidity in the breeding area at the end is greater than or equal to 30% and less than or equal to 60%, then execute the fourth air supply program of the air supply program.

[0055] Specifically, the fourth air supply program of the air supply program can be constant temperature, filtration, and no dehumidification.

[0056] S524. If the relative humidity in the breeding area at the end is less than 30%, then execute the fifth air supply program of the air supply program.

[0057] Specifically, the fifth air supply program of the air supply program can be constant temperature, filtration, and reduction of dehumidification power.

[0058] S525. If the relative humidity in the breeding area at the end is greater than 60%, then execute the sixth air supply program of the air supply program.

[0059] Specifically, the sixth air supply program of the air supply program can be constant temperature, filtration, and increase of dehumidification power.

[0060] The heat, odor, and water vapor evaporated from the materials generated during the growth of insect larvae and their synergistic process with microorganisms will randomly overflow throughout the breeding workshop. At this time, the use of breeding workshop environmental control can reduce the environmental control energy consumption, and thus greatly reduce the breeding cost of insect larvae.

[0061] When the insect larvae are in the stage of rapid feeding and rapid growth, the materials generate a large amount of heat and evaporate a large amount of water vapor into the air. It is necessary to discharge the moisture through ventilation or dehumidify it through a dehumidification system. The ventilation and dehumidification of the breeding workshop are easy and low-cost.

[0062] In an embodiment of the present application, S600 includes:

[0063] S610. Select a breeding area from a breeding area adjacent to the end to a breeding area at the first stage.

[0064] S620. Detect the temperature of the selected breeding area.

[0065] S630. Based on the temperature of the selected breeding area, determine whether the temperature of the selected breeding area is greater than or equal to 26 degrees Celsius and less than or equal to 32 degrees Celsius.

[0066] S640. If the temperature of the selected breeding area is greater than or equal to 26 degrees Celsius and less than or equal to 32 degrees Celsius, then execute the first air supply program of the air supply program.

[0067] Specifically, the first air supply program can be implemented alone, or the first air supply program can also be combined with the fourth air supply program or the fifth air supply program or the sixth air supply program of the air supply program.

[0068] S650, if the temperature of the selected breeding area is less than 26 degrees Celsius, then execute the second air supply program of the air supply program.

[0069] Specifically, the second air supply program can be implemented alone, or the second air supply program can also be combined with the fourth air supply program or the fifth air supply program or the sixth air supply program of the air supply program.

[0070] S660, if the temperature of the selected breeding area is greater than 32 degrees Celsius, then execute the third air supply program of the air supply program.

[0071] Specifically, the third air supply program can be implemented alone, or the third air supply program can also be combined with the fourth air supply program or the fifth air supply program or the sixth air supply program of the air supply program.

[0072] S670, return to a breeding area from the breeding area adjacent to the selected end to the breeding area at the first section until all breeding areas from the breeding area adjacent to the end to the breeding area at the first section are selected.

[0073] This embodiment relates to a method for regulating the temperature of the breeding environment of insect larvae. In the later stage of the growth of insect larvae, that is, in several breeding workshops at the end, the heat of the material gradually decreases, and the material temperature also decreases accordingly. In the early stage of the growth of insect larvae, that is, in the breeding workshops at the head and middle parts, a large amount of moisture generated is likely to cause the material to get damp, affecting the subsequent screening of insects and insect feces. If reverse air supply is adopted, the overall environmental humidity can be controlled at a moderate level, which not only makes the moisture content of the material in the initial stage of larval growth moderate, improves the larval feeding rate, and enhances the conversion rate, but also greatly reduces the dehumidification cost.

[0074] In the cold season, to reduce the growth period of larvae, it is necessary to heat the breeding environment to ensure the activity of larvae. The solution of the breeding workshop can reduce the space for heating, thereby reducing the heating cost.

[0075] This application provides a control system for the breeding environment of insect larvae.

[0076] As Figure 2 shown, in an embodiment of this application, a control system for the breeding environment of insect larvae includes a processor 100, a breeding workshop 200, an air supply device 300, an exhaust device 400, and a temperature sensor 500.

[0077] The processor 100 is used to execute the above-mentioned method for controlling the breeding environment of insect larvae.

[0078] A breeding workshop 200 is parked in a breeding area, and the adjacent breeding workshops 200 are connected in sequence.

[0079] The air supply device 300 is electrically connected to the processor 100, and the air supply device 300 is in communication with the breeding workshop 200 at the end.

[0080] The exhaust device 400 is electrically connected to the processor 100, and the exhaust device 400 is in communication with the breeding workshop 200 at the head.

[0081] The temperature sensor 500 is communicatively connected to the processor 100, and the temperature sensor 500 is arranged in each breeding workshop 200.

[0082] This embodiment relates to an insect larva breeding environment control system. The processor 100 can take the growth time of insect larvae in days, divide the growth time of insect larvae, determine the number of breeding areas and the arrangement shape of breeding areas, and a breeding workshop 200 is parked in a breeding area. The control processes of the air supply device 300 and the exhaust device 400 are simple, the control is convenient, and it is easy to automatically adjust the insect larva breeding environment. According to the arrangement shape of the breeding areas, the air supply program is executed at one end of the same breeding area, and the exhaust program is executed at the other end of the same breeding area. Using the breeding workshop as the air duct reduces the air supply and exhaust pipes and valves in the workshop, and reduces the equipment investment. Under the same environmental control conditions, due to the smaller cross-sectional area of the channel, a faster air speed can be achieved with a smaller air change volume, which is beneficial to heat dissipation and water evaporation, and greatly reduces the air treatment cost. Due to the reverse air supply, based on the measurement data of the temperature sensor 500, the processor 100 adjusts the air supply device 300 and the exhaust device 400, and the warm air flow generated in the middle area of the breeding can heat the low-temperature materials in the breeding area at the head, and there is no need to set up a heating device.

[0083] As Figure 2 shown, in an embodiment of the present application, the structures of each breeding workshop 200 are the same. An air supply hole 211 is provided on the first side wall 210 of the breeding workshop 200. An exhaust hole 221 is provided on the second side wall 220 of the breeding workshop 200. The exhaust hole 221 and the air supply hole 211 of the adjacent breeding workshops 200 are in communication with each other.

[0084] The structures of each temperature sensor 500 are the same. The temperature sensor 500 is arranged in the inner cavity of the breeding workshop 200. The temperature sensor 500 is arranged at the top end of the breeding workshop 200.

[0085] The air supply device 300 is provided with a filter 310. The filter 310 is attached to the air inlet end of the air supply device 300. The air supply device 300 is further provided with a heater 320, a cooler 330 and a dehumidifier 340. The heater 320 is attached to one side of the inner cavity at the air outlet end of the air supply device 300. The cooler 330 is attached to the other side of the inner cavity at the air outlet end of the air supply device 300. The dehumidifier 340 is arranged between the cooler 330 and the body of the air supply device 300.

[0086] Specifically, air supply holes 211 and exhaust holes 221 are provided in the second breeding area to the (n - 1)th breeding area. The air supply holes 211 and the exhaust holes 221 are arranged on different sides of the breeding workshop 200. The air supply holes 211 of the terminal breeding workshop 200 and the exhaust holes 221 of the first breeding workshop 200 are connected to the air supply device 300 and the exhaust device 400 through air ducts. A temperature sensor is provided near the top of the breeding workshop 200. When the temperature sensor 500 detects that the gas temperature in the breeding workshop 200 exceeds the set value, the fan and the cooler are turned on, and the gas in the breeding room is cooled by the cooler and then sent back to the breeding room again, so that the temperature in the breeding workshop 200 is kept constant at 26 degrees Celsius to 32 degrees Celsius.

[0087] More specifically, based on the filter 310 at the air inlet end of the air supply device 300, the air supply device 300 filters the outside air. The dehumidifier 340 is arranged at the air outlet end of the air supply device 300, and the dehumidifier 340 adjusts the humidity of the outside air. The dehumidifier 340 can adjust the humidity of the supplied air. When the dehumidifier 340 increases the dehumidification power, the humidity of the supplied air will decrease. When the dehumidifier 340 reduces the dehumidification power, the humidity of the supplied air will increase. The heater 320 is attached to one side of the inner cavity at the air outlet end of the air supply device 300, and the cooler 330 is attached to the other side of the inner cavity at the air outlet end of the air supply device 300. The heater 320 and the cooler 330 can realize the heating or cooling of the supplied air.

[0088] Based on the phased environmental control of insect larva breeding in the breeding workshop 200, insect larvae at different growth stages are placed in different breeding workshops 200, and then the breeding environment of each breeding workshop 200 is controlled. Each breeding workshop needs to be equipped with heating, cooling, dehumidifying, deodorizing and other systems. On the one hand, the investment cost and floor area are greatly reduced, and on the other hand, the operation and management costs are reduced.

[0089] The technical features of the above-described embodiments can be combined arbitrarily, and there is no limitation on the execution order of each method step. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0090] The embodiments described above merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
