Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to intelligent equipment and feeding method for precise feeding of large yellow croaker guided by machine vision. Background Technology

[0002] As an important economically important aquaculture fish, the large yellow croaker has seen its large-scale and intensive aquaculture scale continuously expand in recent years due to increasing consumer demand. Feeding is a core control point in the large yellow croaker farming process, directly affecting survival rate, growth rate, feed utilization rate, and the quality of the aquatic environment, thus playing a decisive role in the economic benefits of aquaculture. Currently, feeding methods in large yellow croaker farming are mainly divided into two categories: manual feeding and traditional mechanical feeding. Manual feeding relies on the practical experience of the farmers to judge the feeding location, amount, and frequency, resulting in low efficiency, high labor costs, and significant influence from subjective human factors, easily leading to uneven feeding. Traditional mechanical feeding equipment is mostly a fixed-point feeding structure, usually feeding at preset times and in preset quantities, lacking the ability to perceive and respond to the real-time distribution of the fish population. To address this, existing technologies include intelligent feeding devices, such as the existing technology KR1020250080440A. An automatic feeding control device and method for aquaculture farms using artificial intelligence has been developed. The device includes a memory stored in a feeding artificial intelligence model trained to analyze water surface images of aquaculture tanks, and a processor that determines whether to feed the aquaculture tanks by inputting water surface images into the feeding artificial intelligence model. The feeding artificial intelligence model is trained based on original images of a large number of fish on the water surface of the aquaculture tanks and the feeding patterns of the fish. However, existing artificial intelligence feeding modes that rely on human experience or fixed procedures are no longer sufficient to meet the needs of efficient large yellow croaker farming. Summary of the Invention

[0003] The purpose of this invention is to provide intelligent equipment and feeding method for precise feeding of large yellow croaker guided by machine vision, which solves the problems of low efficiency of manual feeding and the inability of traditional mechanical feeding equipment to adapt to the movement of fish schools due to fixed-point placement.

[0004] To address the aforementioned technical problems, this invention provides the following technical solution: a machine vision-guided intelligent feeding device for large yellow croaker, comprising a frame, a float on the frame, a feeding component on the float, and a moving component below the frame. The moving component includes a moving frame, a driver, and an image acquisition device. A control box is located above the center of the frame. After acquiring an image, the image acquisition device feeds it back to the control box, which then controls the driver to move the frame and float, thereby controlling the feeding position of the feeding component. This invention uses the frame as a support structure, with the float providing buoyancy to support the feeding component, forming a feeding scheme in conjunction with the moving component below the frame. The image acquisition device on the moving frame can capture images of the fish distribution in real time. After feeding the data back to the control box, the control box immediately regulates the driver to move the frame and float synchronously, ensuring that the feeding component accurately targets the core feeding area of ​​the fish. This solves the problems of low efficiency of manual feeding and fixed positions of traditional mechanical feeding, enabling the feeding position to match the fish population when feeding is needed, reducing feed waste, lowering breeding costs, and reducing the risk of water pollution caused by uneaten feed accumulation.

[0005] The mobile frame is equipped with a monitor to monitor the water temperature, dissolved oxygen, and light intensity at the location of the intelligent feeding equipment. The monitor moves synchronously with the mobile components, capturing environmental parameters such as water temperature, dissolved oxygen, and light intensity in the feeding area in real time and feeding the data back to the control box. The control box then combines this data with images of fish distribution collected by the image acquisition device to make a comprehensive judgment.

[0006] According to one embodiment of the present invention, a float is provided at the bottom of the mobile frame. The float at the bottom of the mobile frame is used to provide stable buoyancy, prevent the mobile components from sinking or tilting due to their own weight, and ensure that the monitor accurately monitors parameters such as water temperature, dissolved oxygen, and light, thereby reducing the collection error and feeding deviation caused by equipment imbalance.

[0007] According to one embodiment of the present invention, the feeding assembly includes a second housing with a built-in storage chamber and a lid. A discharge cylinder communicating with the bottom side of the second housing is provided, with a first opening at the bottom and a built-in first rotating component capable of sealing or opening the first opening. The storage chamber of the second housing stores bait, and the lid provides a sealed protection. Furthermore, the discharge cylinder at the bottom of the second housing provides an output channel for the bait, guiding it to flow towards the first opening. The built-in first rotating component seals or opens the first opening by rotation and can also adjust the opening size to control the bait's falling rate and total amount. This solves the problem of traditional feeding methods lacking precise quantity control components and easily resulting in overfeeding or underfeeding, enabling on-demand feeding and improving bait utilization.

[0008] According to one embodiment of the present invention, a first housing is provided on one side of the second housing. A motor is built into the first housing, and the motor output end passes through the second housing and is coaxially connected to a first rotating component. A base plate is connected to the bottom of both the second and first housings, and the base plate is detachably connected to a float at the bottom. The first housing provides a sealed protective space for the built-in motor, wherein the motor output end is coaxially connected to the first rotating component to transmit power to the first rotating component and ensure its rotation. The second housing and the first housing are integrated via a base plate, and the base plate is detachably connected to the float, facilitating quick assembly and disassembly of the feeding assembly.

[0009] According to one embodiment of the present invention, a second rotating member is coaxially connected to one side of the first rotating member. An air pump is mounted on the float, and the air pump has a first pipe communicating with a discharge cylinder. The outlet of the first pipe is located inside the discharge cylinder. The outlet of the first pipe faces the second rotating member. The airflow generated by the air pump blows directly onto the second rotating member through the first pipe, which assists the first rotating member in controlling the rapid dispersion of falling bait. The synchronous rotation of the first and second rotating members helps to make the bait spread more evenly, reducing bait waste. Simultaneously, the impact of the airflow and the rotation of the second rotating member can break up clumps of bait, preventing blockages in the discharge cylinder and ensuring continuous feeding. Furthermore, by adjusting the airflow intensity of the air pump, the bait diffusion range can be adjusted in conjunction with the opening size of the first rotating member to suit the needs of fish populations of different densities.

[0010] According to one embodiment of the present invention, the second rotating component includes a rotating disk, with a connecting sleeve coaxially connected to the first rotating component at its center. A blade plate connected to the rotating disk is arranged around the side of the connecting sleeve. A through hole, forming a circular ring structure, is provided in the center of the rotating disk. The connecting sleeve in the center of the rotating disk achieves coaxial connection with the first rotating component, ensuring synchronous rotation. The blade plate surrounding the side of the connecting sleeve can receive the airflow blown out by the first pipe. The airflow impacts the blade plate, driving the rotating disk to rotate. Combined with the stirring action of the blade plate, the bait controlled by the first rotating component is fully dispersed. The circular ring structure and the through hole in the center of the rotating disk provide a falling channel for the bait while preventing the rotating disk from obstructing the bait, allowing the dispersed bait to spread evenly along the edge of the rotating disk.

[0011] According to one embodiment of the present invention, a first air hole penetrating the rotating disk is provided around the side of the rotating disk, and second air holes penetrating the rotating disk and communicating with the first air hole are provided around the upper and lower surfaces of the rotating disk. The airflow blown out by the air pump through the first pipe body, in addition to driving the impeller to rotate the rotating disk, can also enter through the first air hole on the side of the rotating disk and then be ejected from the second air holes on the upper and lower surfaces, forming a multi-directional airflow pattern. This multi-directional airflow can both further disperse the bait falling from the first rotating component, thoroughly breaking up any clumps of bait, and promote the diffusion of bait in multiple directions (up, down, left, and right), improving the uniformity and range of bait coverage. Simultaneously, the circulating airflow can sweep the surface of the rotating disk and the inside of the air holes, preventing bait from sticking and clogging the air holes or adhering to the rotating disk, ensuring smooth bait discharge.

[0012] According to one embodiment of the present invention, a flow stabilizing component is arrayed below the float. The flow stabilizing component includes two first discs spaced vertically apart, with a guide vane circumferentially connected between the two first discs. The upper first disc has an opening in its center, and a connecting disc is rotatably connected to the lower first disc. The connecting disc is detachably connected to the bottom of the float via a first column. The opening in the center of the upper first disc guides water flow into the space between the two discs, forming a stable flow field after being rectified by the guide vane. This effectively reduces water flow disturbance and prevents the bait discharged from the discharge cylinder from being scattered and deflected by turbulent flow, ensuring that the bait covers the fish school area located by the image acquisition device. The lower first disc is rotatably connected to the connecting disc and can rotate slightly with the water flow, buffering the impact of the water flow on the float to ensure the stability of the frame and the float's attitude. The connecting disc is detachably connected to the float via the first column.

[0013] According to one embodiment of the present invention, the frame is a cross structure, and floats are disposed at each end of the frame. The cross structure of the frame and the placement of floats at each end enable buoyancy to be evenly distributed around the frame, preventing the equipment from tilting or tipping over due to a shift in the center of gravity.

[0014] A feeding method for a machine vision-guided intelligent equipment for precise feeding of large yellow croaker is described below: Step 1) When the equipment is started, the control box in the middle of the frame triggers the operation of the moving component. The image acquisition device on the moving frame begins to collect images of the distribution of fish in the aquaculture area in real time. At the same time, the monitor on the moving frame is started to continuously monitor environmental parameters such as water temperature, dissolved oxygen, and light in the current area. All data are fed back to the control box in real time.

[0015] Step 2) The control box analyzes the image data to locate the core feeding area and density of the fish; it combines the environmental parameters of the monitor to determine whether the current conditions are suitable for the large yellow croaker to feed, and generates instructions such as feeding location, feeding amount and diffusion range.

[0016] Step 3), the control box drives the drive on the mobile frame to move the frame and end floats; the float at the bottom of the mobile frame provides stable buoyancy to prevent the moving components from tilting, ensuring that the equipment reaches the fish area and the feeding components are aligned with the feeding point.

[0017] Step 4) The control box starts the motor in the first box, and the motor output drives the first rotating component to rotate, opening the first opening at the bottom of the discharge cylinder. The bait in the storage chamber of the second box falls through the discharge cylinder. At the same time, the air pump on the float is started. The airflow blows through the first pipe to the second rotating component, impacting the blade and driving the rotating disk to rotate. When the bait falls through the through hole in the middle of the rotating disk, it is dispersed by the blade. At the same time, the airflow enters through the first air hole and is sprayed out through the second air hole, realizing the multi-directional uniform diffusion of the bait.

[0018] Step 5) When the image shows that the fish are feeding less or the preset feeding amount has been reached, the control box instructs the motor to rotate the first rotating part to seal the first opening and shut down the air pump; then the drive driver drives the device back to the initial position, the monitor and image acquisition device enter standby mode, and the control box stores the feeding data for this feeding.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention integrates an image acquisition device, a monitor, a driver, a feeding component, and a flow stabilization component to ensure that the feeding position matches the feeding area of ​​the fish, and that the feeding amount and diffusion range are adapted to the fish density and environmental conditions, thereby reducing feed waste and water pollution caused by uneaten feed deposition.

[0023] 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.

[0024] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: As shown in the attached figure Figure 1 - Appendix Figure 7As shown, the machine vision-guided precision feeding intelligent equipment for large yellow croaker includes a frame 10, on which a float 11 is mounted, and a feeding component 60 is installed on the float 11. Below the frame 10 is a moving component 20, which includes a moving frame 21, on which a driver 23 and an image acquisition device 22 are mounted. Furthermore, a control box 40 is located above the middle of the frame 10. After acquiring an image, the image acquisition device 22 feeds it back to the control box 40, which then controls the driver 23 to move, thereby moving the frame 10 and the float 11, and thus controlling the feeding position of the feeding component 60. This invention uses the frame 10 as a supporting framework, and the float 11 provides buoyancy to support the feeding component 60, forming a feeding scheme in conjunction with the moving component 20 below the frame 10. The image acquisition device 22 on the mobile frame 21 can capture images of the fish distribution in real time. After the data is fed back to the control box 40, the control box 40 immediately controls the operation of the drive 23, which drives the frame 10 and the float 11 to move synchronously, so that the feeding component 60 is precisely aimed at the core feeding area of ​​the fish. This solves the problems of low efficiency of manual feeding and fixed position of traditional mechanical feeding, and realizes that the feeding position matches the fish when feeding is needed, reducing feed waste, lowering breeding costs, and reducing the risk of water pollution caused by uneaten feed.

[0026] A monitor is installed on the mobile frame 21 to monitor the water temperature, dissolved oxygen, and light intensity at the location of the intelligent feeding equipment. The monitor on the mobile frame 21 can move synchronously with the mobile component 20, capturing environmental parameters such as water temperature, dissolved oxygen, and light intensity in the feeding area in real time, and feeding the data back to the control box 40. The control box 40 makes a comprehensive judgment based on the fish distribution images collected by the image acquisition device 22.

[0027] The bottom of the mobile frame 21 is equipped with a float 24. The float 24 at the bottom of the mobile frame 21 is used to provide stable buoyancy, prevent the mobile component 20 from sinking or tilting due to its own weight, and ensure that the monitor accurately monitors parameters such as water temperature, dissolved oxygen, and light, thereby reducing the collection error and feeding deviation caused by equipment imbalance.

[0028] The feeding assembly 60 includes a second housing 63, which has a storage chamber inside and a lid 63 on top. A discharge cylinder 64, connected to the bottom of the second housing 63, is located on one side of the bottom. The discharge cylinder 64 has a first opening 67 at its bottom and a first rotating component 66 inside. This first rotating component 66 can seal or open the first opening 67. The storage chamber of the second housing 63 stores bait, and the lid 63 provides a sealed protection. Furthermore, the discharge cylinder 64 at the bottom of the second housing 63 provides an output channel for the bait, guiding it to the first opening 67. The built-in first rotating component 66 seals or opens the first opening 67 by rotation and can also adjust the opening size to control the bait's falling rate and total amount. This solves the problems of traditional feeding methods lacking precise quantity control components and easily resulting in overfeeding or underfeeding, enabling on-demand feeding and improving bait utilization.

[0029] A first housing 61 is disposed on one side of the second housing 63. A motor is housed inside the first housing 61, and the output end of the motor passes through the second housing 63 and is coaxially connected to the first rotating component 66. The bottoms of the second housing 63 and the first housing 61 are connected to a base plate 65, which is detachably connected to the float 11 below. The first housing 61 provides a sealed protective space for the built-in motor, and the motor output end is coaxially connected to the first rotating component 66 to transmit power to ensure its rotation. The second housing 63 and the first housing 61 are integrated via the base plate 65, which is detachably connected to the float 11, facilitating quick assembly and disassembly of the feeding assembly 60.

[0030] A second rotating component 68 is coaxially connected to one side of the first rotating component 66. An air pump 50 is mounted on the float 11. The air pump 50 has a first pipe 51 connected to the discharge cylinder 64, with the outlet of the first pipe 51 located inside the discharge cylinder 64. The outlet of the first pipe 51 faces the second rotating component 68. The airflow generated by the air pump 50 blows directly onto the second rotating component 68 through the first pipe 51, assisting the first rotating component 66 in controlling the rapid dispersion of falling bait. The synchronous rotation of the first rotating component 66 and the second rotating component 68 helps to distribute the bait more evenly, reducing bait waste. Simultaneously, the airflow impact and the rotation of the second rotating component 68 break up clumps of bait, preventing blockages in the discharge cylinder 64 and ensuring continuous feeding. Furthermore, by adjusting the airflow intensity of the air pump 50, the bait dispersion range can be adjusted in conjunction with the opening size of the first rotating component 66 to suit the needs of fish populations of different densities.

[0031] The second rotating component 68 includes a rotating disk 681. A connecting sleeve 685, coaxially connected to the first rotating component 66, is located in the center of the rotating disk 681. A blade 684, connected to the rotating disk 681, surrounds the side of the connecting sleeve 685. The rotating disk 681 has a through hole in its center, forming a circular ring structure. The connecting sleeve 685 in the center of the rotating disk 681 achieves coaxial connection with the first rotating component 66, ensuring synchronous rotation. The blade 684 surrounding the side of the connecting sleeve 685 can receive the airflow blown out by the first pipe 51. The airflow impacts the blade 684, driving the rotating disk 681 to rotate. Combined with the stirring action of the blade 684, the bait controlled by the first rotating component 66 is thoroughly dispersed. The circular ring structure and central through hole of the rotating disk 681 provide a falling channel for the bait while preventing the rotating disk 681 from obstructing the bait, allowing the dispersed bait to spread evenly along the edge of the rotating disk 681.

[0032] The rotating disk 681 has a first air hole 682 extending through its body around its side, and second air holes 683 extending through its body around its upper and lower sides, with the second air holes 683 communicating with the first air hole 682. The airflow blown by the air pump 50 through the first pipe 51, in addition to driving the impeller 684 to rotate the rotating disk 681, can also enter through the first air hole 682 on the side of the rotating disk 681 and then exit through the second air holes 683 on the upper and lower sides, forming a multi-directional airflow pattern. This multi-directional airflow not only further disperses the bait falling from the first rotating component 66, thoroughly breaking up any clumps, but also propels the bait to spread in multiple directions (up, down, left, and right), improving the uniformity and coverage of the bait distribution. Simultaneously, the flowing airflow can clean the surface of the rotating disk 681 and the interior of the air holes, preventing bait from sticking and clogging the air holes or adhering to the rotating disk 681, ensuring smooth bait discharge.

[0033] A flow stabilizing assembly 30 is arrayed below the float 11. The flow stabilizing assembly 30 includes two first discs 33 spaced vertically, with a guide vane 34 circumferentially connected between them. The upper first disc 33 has an opening in the middle, and a connecting disc 32 is rotatably connected to the lower first disc 33. The connecting disc 32 is detachably connected to the bottom of the float 11 via a first column 31. The opening in the middle of the upper first disc 33 guides water flow into the space between the two discs. After being rectified by the guide vane 34, a stable flow field is formed, effectively reducing water flow disturbance and preventing the bait discharged from the discharge cylinder 64 from being scattered and deflected by turbulent flow, ensuring that the bait covers the fish area located by the image acquisition device 22. The lower first disc 33 is rotatably connected to the connecting disc 32 and can rotate slightly with the water flow, buffering the impact of the water flow on the float 11 to ensure the stability of the frame 10 and the float 11. The connecting disc 32 is detachably connected to the float 11 via the first column 31.

[0034] The frame 10 has a cross-shaped structure, with floats 11 located at each end of the frame 10. The cross-shaped structure of the frame 10 and the placement of floats 11 at each end ensure that buoyancy is evenly distributed around the frame 10, preventing the equipment from tilting or overturning due to a shift in the center of gravity. The accompanying drawings show a single float 11 equipped with a feeding assembly 60, an air pump 50, etc. In actual use, different numbers of floats 11 can be selected to accommodate the feeding assembly 60 and air pump 50 as needed.

[0035] A feeding method for a machine vision-guided intelligent equipment for precise feeding of large yellow croaker is described below: Step 1) When the equipment is started, the control box 40 in the middle of the frame 10 triggers the operation of the moving component 20. The image acquisition device 22 on the moving frame 21 begins to collect images of the distribution of fish in the aquaculture area in real time. Simultaneously, the monitor on the moving frame 21 is started to continuously monitor environmental parameters such as water temperature, dissolved oxygen, and light in the current area. All data are fed back to the control box 40 in real time.

[0036] Step 2) The control box 40 analyzes the image data to locate the core feeding area and density of the fish; it combines the environmental parameters of the monitor to determine whether the current conditions are suitable for the large yellow croaker to feed, and generates instructions such as feeding location, feeding amount and diffusion range.

[0037] Step 3), the control box 40 drives the drive 23 on the mobile frame 21 to move the frame 10 and the end float 11; the float 24 at the bottom of the mobile frame 21 provides stable buoyancy to prevent the mobile component 20 from tilting, ensuring that the equipment reaches the fish area and the feeding component 60 is aligned with the feeding point.

[0038] Step 4) The control box 40 starts the motor in the first box 61. The motor output drives the first rotating part 66 to rotate, opening the first opening 67 at the bottom of the discharge cylinder 64. The bait in the storage chamber of the second box 63 falls through the discharge cylinder 64. Simultaneously, the air pump 50 on the float 11 is started. The airflow blows through the first pipe 51 to the second rotating part 68, impacting the blade 684 and driving the rotating disk 681 to rotate. When the bait falls through the through hole in the middle of the rotating disk 681, it is dispersed by the blade 684. At the same time, the airflow enters through the first air hole 682 and is sprayed out through the second air hole 683, realizing the multi-directional uniform diffusion of the bait.

[0039] Step 5) When the image shows that the fish are feeding less or the preset amount of feed has been reached, the control box 40 instructs the motor to drive the first rotating part 66 to rotate and seal the first opening 67, and shuts off the air pump 50; then the drive driver 23 drives the device back to the initial position, the monitor and image acquisition device 22 enter the standby state, and the control box 40 stores the feeding data for this time.

[0040] Example 2: This embodiment is based on the technical solution of Embodiment 1, see appendix. Figure 8 - Appendix Figure 9 As shown, it also includes: a first column 31 including a column with an opening at the upper end, a first screw 12 being threaded to the bottom of the float 11, and the first screw 12 being connected to the upper end of the column through a transition sleeve 312, with threaded structures for connecting the first screw 12 and the upper end of the column respectively on the inner and outer sides of the transition sleeve 312.

[0041] Inside the column, there is a threaded post 311 coaxial with it. One end of the threaded post is located inside the column, and the end of the first screw 12 located inside the column is connected to a spring. The spring can contact the end of the threaded post 311. The other end of the threaded post 311 is located outside the column. The threaded post 311 can move relative to the column, that is, the column has a through hole that allows the column to pass through. A protruding ring is provided on the threaded post inside the column, and there is a spring structure between the protruding ring and the bottom of the column.

[0042] The upper end of the column is connected to the first screw 12 via the internal and external threaded structure of the transition sleeve 312, allowing for quick disassembly and assembly, facilitating maintenance and replacement, and ensuring coaxiality of the connection. The coaxial threaded post 311 inside the column, in conjunction with the spring at the end of the first screw 12, the convex ring, and the spring at the bottom of the column, forms a double buffer structure. This structure absorbs stress generated by water fluctuations, equipment movement, or water flow impact, preventing damage due to stress concentration at the connection between the first column 31 and the float 11. Simultaneously, the buffer structure reduces the impact of impacts on the flow stabilization component 30, ensuring that the two first discs 33 and the guide vane 34 maintain a stable posture.
