Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a device for monitoring the swimming posture of sturgeon fry. Background Technology

[0002] In aquaculture, aquaculture units typically require technicians to conduct daily inspections of each pond to observe the growth and swimming behavior of aquatic organisms and determine their health status. However, due to labor costs and workload, most aquaculture units can only conduct these inspections during daily feeding times.

[0003] Taking sturgeon farming as an example, the traditional standard by which experienced aquaculture technicians judge the most prominent abnormal swimming posture of sturgeon fry is: the fry maintains its entire lower surface of mouth and abdomen facing the water surface for an extended period, with its entire body floating on the surface, essentially ceasing large-scale muscle movements, only slightly wiggling its head and tail to move slowly with the water waves. However, after a period of time, the fry will flip over and resume normal swimming posture. This switching of swimming posture will occur repeatedly before any intervention measures are taken. However, manual monitoring of swimming posture is firstly lacking in real-time accuracy, and the frequency of inspections is far from sufficient for sturgeon fry farming that requires timely intervention; secondly, the accuracy rate is low, as manual inspection relies on the visual observation and experience of aquaculture technicians, leading to a high possibility of misjudgment and making it impossible to objectively and accurately characterize the abnormal swimming behavior of sturgeon fry.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following description, in conjunction with the accompanying drawings, describes the sturgeon fry swimming posture monitoring device (hereinafter referred to as the device) of this utility model. Figure 1 As shown, Figure 1 This is a schematic diagram of the sturgeon fry swimming behavior monitoring device provided by this utility model. Specifically, the sturgeon fry swimming behavior monitoring device includes: a fixing plate 1, a calibration plate 2, a sleeve 3, a camera platform 4, a camera 5, a workbench 6, and a light and buzzer alarm 7.

[0024] Fixing plate 1 is fixed to the bottom surface of the sturgeon fry rearing area. The bottom of fixing plate 1 is horizontal, with dimensions of 15cm x 15cm and a thickness of 0.1cm. Four fixing plates are laid on the bottom surface to stably support other components above. The number of fixing plates 1 can be determined based on the area of ​​the sturgeon fry rearing area. Figure 1 Four are shown. It should be noted that the water areas for raising sturgeon fry here are regular quadrilaterals, such as squares or rectangles.

[0025] The calibration plate 2 is a black circular plate with a diameter of 10cm. The number of calibration plates 2 is the same as the number of fixed plates 1. Each fixed plate 1 is welded to a calibration plate 2 on the bottom surface. For example, a non-rusting metal rod or pipe is used for welding to ensure that the positions of the fixed plate 1 and the calibration plate 2 on the bottom surface are fixed and do not change with the movement of the water.

[0026] The camera platform 4 is square in shape, with a planar dimension of 30cm x 30cm and a thickness of 0.1cm, and has four corner edges 8. The camera platform 4 is erected on the water surface of the sturgeon fry rearing area. Each fixing plate 1 is fixedly connected to the corner edge 8 of the camera platform 4 via a sleeve 3. Here, the four fixing plates 1 serve as the base of the camera platform, and the four sleeves 3 connect to the four corner edges 8 of the camera platform 4, supporting the camera platform 4 and allowing it to be erected on the water surface of the sturgeon fry rearing area.

[0027] Camera 5 can be an industrial camera that uses frame exposure, has a maximum image resolution of 2448×2048, a frame rate of 20fps, is equipped with an 8mm fixed-focus lens, has an adjustable aperture range of F2.0 to F16, a field of view of 68°×57°×44°, and a focusing range greater than 0.15m.

[0028] The light and buzzer alarm 7 can receive signal commands and accordingly light up the alarm light, which can flash red light and emit a buzzer alarm sound.

[0029] Both camera 5 and the light and buzzer alarm 7 are mounted on camera platform 4. Camera 5 can be installed at the bottom of the plane of camera platform 4 or fixed on the plane of camera platform 4, but a viewfinder window needs to be set on camera platform 4. The shooting angle of camera 5 is always facing the sturgeon fry breeding water area. A fixed shooting time interval is set during shooting, so that camera 5 automatically captures images of sturgeon fry swimming at each shooting time interval, thus ensuring that four calibration plates 2 are present in each image of sturgeon fry swimming.

[0030] The light and buzzer alarm 7 can be adhered and fixed to the plane of the camera platform 4 with waterproof adhesive. The light and buzzer alarm 7 is connected to the workbench 6 via a serial cable 10, and the workbench 6 is connected to the camera 5 via a network cable 9. This ensures that the swimming posture images of sturgeon fry automatically captured by the camera 5 can be uploaded to the workbench 6 in real time via the network. The workbench 6 is an electronic device that can detect abnormal swimming postures of sturgeon fry in the swimming posture images, and can be a desktop computer or a desktop chassis device.

[0031] During abnormal swimming behavior detection, the workbench 6 can also send a signal command to the light and buzzer alarm 7 via the serial port 10 after detecting abnormal swimming behavior in sturgeon fry. Upon receiving the signal command, the light and buzzer alarm 7 will light up a red light and sound an alarm to remind the fish farmers that the sturgeon fry have abnormal swimming behavior and to take appropriate measures in a timely manner. If the workbench 6 does not detect abnormal swimming behavior in sturgeon fry during the abnormal swimming behavior detection, it is not necessary to send a signal command to the light and buzzer alarm 7.

[0032] In some embodiments, the workbench 6 can also communicate remotely with the light and buzzer alarm 7 and the camera 5 respectively, without the need for serial cable 10 and network cable 9. In this way, the workbench 6 can be a remote computer, tablet or portable mobile device (such as a mobile phone) to simplify device wiring.

[0033] This invention, through the aforementioned sturgeon fry swimming behavior monitoring device, achieves real-time monitoring of sturgeon fry swimming behavior without the need for manual inspection, thus saving manpower. Furthermore, it overcomes the limitation of manual inspection in objectively and accurately identifying abnormal swimming behaviors in sturgeon fry.

[0034] In some embodiments, such as Figure 1As shown, the sleeve 3 is fixedly connected to the edge corner 8 of the camera platform 4 via an angle adjustment joint 11, and the fixing plate 1 is fixedly connected to the sleeve 3 via an angle adjustment joint 11. Since there are four sleeves 3, an angle adjustment joint 11 is set at each sleeve 3 to individually realize the angle adjustment of each sleeve 3.

[0035] In some scenarios, when the water level in the sturgeon fry breeding area fluctuates, it is generally necessary to adjust the horizontal position and imaging height of the camera platform 4. Here, the angle adjustment joint 11 can be used to adjust the angle of the four sleeves 3, so that the position of the camera platform 4 is fixed and the imaging plane of the camera 5 and the calibration plane of the fixed plate 1 are horizontal.

[0036] like Figure 3 As shown, the angle adjustment joint 11 includes a ball head structure 12 and a ball groove structure 13, which are nested together. The ball head structure 12 is installed at both ends of the sleeve 3, while the ball groove structure 13 is installed on the fixed plate 1 and the edge corner 8 of the camera platform, respectively.

[0037] The fixed plate 1 and the sleeve 3 are connected by the contact of the ball head structure 12 and the ball groove structure 13, and the edge corner 8 of the camera platform 4 is connected to the sleeve 3. In this way, the fixed plate 1 serves as the base and the sleeve 3 serves as the supporting component, supporting the camera platform 4. At the same time, since the ball head structure 12 and the ball groove structure 13 can contact and connect in any direction, the angle of the sleeve 3 can be freely and flexibly adjusted.

[0038] This invention enables free and flexible adjustment of the sleeve angle by setting an angle adjustment joint to adapt to changes in the height of the camera platform. The angle adjustment joint utilizes the nested connection and fixation of the ball head structure and ball groove structure to ensure a stable connection between the fixing plate, the sleeve, and the camera platform, thereby improving the stability of the entire device.

[0039] Furthermore, such as Figure 1 As shown, a sleeve extension length adjuster 14 is also installed on the sleeve 3. Because when adjusting the angle of the sleeve 3 using the angle adjustment joint 11, the length of the sleeve 3 connecting the fixing plate 1 and the camera platform 4 needs to be adjusted to accommodate changes in water level, in order to adapt to the adjustment of the support height of the camera platform 4. Therefore, here, the sleeve extension length adjuster 14 is installed on the sleeve 3 to achieve the length adjustment of the sleeve 3, thereby achieving the adjustment of the support height of the camera platform 4.

[0040] The sleeve telescopic length adjuster 14 includes an inner tube and an outer tube, which are connected by a threaded nesting. The spiral nesting of the inner and outer tubes is actually a spiral fastening device. When rotated in one direction, the inner tube retracts into the outer tube, shortening it and reducing the length of the sleeve 3. When rotated in the opposite direction, the inner tube extends out of the outer tube, lengthening it and increasing the length of the sleeve 3.

[0041] Of course, in practice, each sleeve 3 is equipped with a sleeve extension length adjuster 14 to independently adjust the length of the sleeve.

[0042] This invention, through the coordinated operation of the aforementioned sleeve telescopic length adjuster and angle adjustment joint, allows for free and flexible adjustment of the camera platform's support height and imaging plane. While ensuring the stability of the entire device, it enables the operability of horizontal adjustment of the camera platform and adjustment of the imaging height according to changes in the aquaculture water level.

[0043] In some embodiments, such as Figure 2 As shown, in the sturgeon fry swimming behavior monitoring device, the camera platform 4 is also equipped with multiple bolts 15. The number of bolts 15 can be set as needed, generally 4. The camera 5 is equipped with the same number of screw holes as the bolts 15. The screw holes can generally be installed on the back plate of the camera. The camera 5 is fixedly connected to the bolts 15 of the camera platform through the screw holes.

[0044] Here, the screw connection between the bolt and the screw hole ensures that the camera can be fixed on the camera platform, unaffected by external factors, thus guaranteeing the stability and safety of the camera.

[0045] Furthermore, such as Figure 2 As shown, the camera platform 4 also has a camera viewfinder 16 at the shooting angle of the camera 5. That is, a camera viewfinder 16 is set on the plane of the camera platform 4. The shape of the camera viewfinder can be square, circular, or elliptical. Since the shooting angle of the camera 5 needs to be facing the sturgeon fry breeding water area below, this design allows the camera 5 to capture the sturgeon fry breeding water area below through this camera viewfinder 16.

[0046] The camera platform 4 is square in shape, and the camera viewfinder 16 can be located at the center of the camera platform 4. When setting up the device, the angle of the sleeve 3 should be adjusted as much as possible by adjusting the angle of the angle adjustment joint 11 to ensure that the camera platform 4 is set above the water surface at the center of the entire sturgeon fry breeding water area. This will ensure that the camera viewfinder 16 is also in the center of the sturgeon fry breeding water area, so that the shooting angle of the camera 5 can reach the optimal position.

[0047] Therefore, the camera's viewfinder at the center of the camera platform allows the camera to have the optimal shooting angle, ensuring that the imaging range covers the entire sturgeon fry rearing water area and all calibration plates, so as to make the imaging more intuitive.

[0048] Furthermore, such as Figure 2 As shown, a bubble level 17 is also provided on the camera platform 4. The bubble level contains an air bubble, and by observing whether the air bubble is in the center of the level, it is easy to accurately determine the levelness of the camera platform 4, ensuring that the imaging plane of the camera 5 is level.

[0049] In some embodiments, the camera 5 is equipped with an image sensor, specifically a high-definition color image sensor based on a charge-coupled device (CCD), capable of converting optical images into digital signals. Furthermore, the image sensor has a gigabit Ethernet port connected via a network cable 9 for connecting to the workbench 6, providing power to the camera 5 and a link for image data transmission. Alternatively, if the workbench 6 is remote, the image sensor can also be configured with a wireless network device to connect to it.

[0050] Here, by setting an image sensor on the camera to acquire images of sturgeon fry swimming, the quality of the camera image can be improved as much as possible. By setting up a gigabit network port, the acquired images of sturgeon fry swimming can be uploaded to the workbench for processing in a timely manner, ensuring the real-time nature of the images.

[0051] In some embodiments, the workbench 6 includes a metal grid heat dissipation chassis, which is equipped with a signal transmission network port for serial cable connection. Through this port, signal commands can be transmitted to the light and buzzer alarm 7 via the serial cable 10, enabling real-time alarm transmission. Alternatively, if the workbench 6 is remote, a wireless network device can be installed in the metal grid heat dissipation chassis to enable wireless communication with the light and buzzer alarm 7 and achieve wireless transmission of signal commands.

[0052] The metal grid heat dissipation chassis uses DC12V power supply. The chassis has a compact structure and integrates various hardware components for storing, processing and recognizing images of sturgeon fry swimming postures. It can identify swimming posture abnormalities in sturgeon fry swimming posture images, output the corresponding swimming posture abnormality recognition results, and send signal commands in a timely manner through the signal transmission network port.

[0053] Here, the storage, processing, and recognition of sturgeon fry swimming images are all integrated into a metal grid heat dissipation enclosure. This integrated approach enables the detection of abnormal swimming behavior in sturgeon fry, reducing the number of components required. Furthermore, the hardware components within the metal grid heat dissipation enclosure provide higher accuracy compared to manual inspection and visual assessment of swimming anomalies.

[0054] Furthermore, the metal grid heat dissipation chassis houses an image acquisition card, a solid-state drive (SSD), and a central processing unit (CPU). Since these modules are all hardware components, during installation, the image acquisition card, SSD, and CPU are connected to the circuit board of the metal grid heat dissipation chassis, achieving integrated functionality across all components.

[0055] The image acquisition card uses the MV-EGigE series gigabit network card, employing the PCI-E bus standard to ensure efficient transmission of sturgeon fry swimming images uploaded from gigabit network ports, enabling high-speed and stable image acquisition. A 1TB SSD high-speed solid-state drive, coupled with 32GB DDR5 memory, supports image data storage and the efficient operation of computer vision algorithms. These computer vision algorithms are used for image processing and recognition of sturgeon fry swimming images, such as the OpenCV algorithm library and image target detection algorithms, to identify abnormal swimming postures. The central processing unit is an Intel i7-14700F, a high-speed processor with 20 cores, utilizing computer vision algorithms for efficient image data processing and analysis.

[0056] In practice, the metal grid heat dissipation chassis is powered directly by DC12V, which starts the circuit board and enables the image acquisition card, solid-state drive and central processing unit connected to the circuit board to operate normally. The image of the swimming posture of sturgeon fry uploaded from the gigabit network port is used to perform the identification of abnormal swimming posture.

[0057] In the specific recognition process of the computer vision algorithm, the sturgeon fry are first identified and located in the swimming posture images of sturgeon fry. The position coordinates of the calibration plate in each image are used as a reference to calculate the relative position change between the position and the reference, and then it is determined whether the sturgeon fry is an abnormal target. Then, based on the duration of the abnormal target, it is finally determined whether the sturgeon fry has abnormal swimming posture, and then the abnormal swimming posture recognition result is output. The signal transmission network port of the metal grid heat dissipation chassis sends out signal commands in a timely manner.

[0058] This invention integrates an image acquisition card, a solid-state drive, and a central processing unit inside a metal grid heat dissipation chassis to achieve image data storage and image processing, thereby overcoming the deficiency that manual inspection cannot objectively and accurately characterize abnormal swimming behavior of sturgeon fry.

[0059] In some embodiments, since some components of the device are installed underwater and others are placed on the water surface, the materials used for the components must meet the requirements of the actual scenario. Here, the angle adjustment joint 11 and the sleeve extension length adjuster 14 are both made of polyethylene plastic material, which has strong wear resistance. The planes of the fixing plate 1, calibration plate 2, sleeve 3, and camera platform 4, as well as the bolts 15 on the planes, are all made of galvanized aluminum alloy material, taking into account lightweight and easy operation, as well as corrosion resistance in high humidity environments.

[0060] This invention utilizes aluminum alloy galvanized material and polyethylene plastic material for some components of the device, thus ensuring the overall structural strength of the device while adapting to various aquaculture water conditions, effectively resisting corrosion and wear, and ensuring the durability of each component.

[0061] Furthermore, the sturgeon fry swimming posture monitoring device provided by this utility model has a certain degree of versatility, that is, it is not limited to monitoring the swimming posture of sturgeon fry. Under the condition that environmental conditions permit, it can be used to monitor the swimming posture of other fish with similar characteristics to sturgeon fry. It still directly obtains the swimming posture image of the corresponding fish by taking pictures and uploading it to the workbench to realize the swimming posture recognition of the corresponding fish.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
