Detailed implementation manners

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1In the specific embodiment shown, a detection device for detecting the lesions of the hepatopancreas of penaeid shrimp based on image detection includes a box body 1 that can be placed in a culture pond. The box body 1 is a hollow shell. One end of the box body 1 is provided with an open inner cavity 2 for penaeid shrimp to enter. The interior of the box body 1 is provided with a passage for penaeid shrimp to pass through. One end of the passage communicates with the open inner cavity 2, and the other end communicates with the outside of the box body 1. A lighting facility 3 is provided on the side wall of the open inner cavity 2. The lighting facility 3 and the passage are arranged on both sides of the open inner cavity 2 correspondingly. The lighting facility 3 is used to supplement light to the open inner cavity 2 and the passage. A camera 4 is provided at the top of the passage for obtaining the back pictures of penaeid shrimp passing through the passage. The camera 4 is wirelessly or wiredly connected to a controller outside the culture pond. The controller is used to control the camera to take pictures of penaeid shrimp and analyze the uploaded images to determine whether the hepatopancreas of penaeid shrimp has lesions. In specific application, a hook can be installed on the top of the box body and suspended in the water of the culture pond through a support rod. The camera and the controller are preferably wirelessly connected. The controller remotely controls the camera to take pictures of penaeid shrimp and uploads the images to the controller for analysis. At the same time, the start and stop of the lighting facility can also be remotely controlled by the controller to save power. When the hepatopancreas of penaeid shrimp has lesions, the back color of penaeid shrimp will turn red, yellow, dark or albino. The camera at the top of the passage can be used to observe the change of the back color of penaeid shrimp. If the back color of penaeid shrimp is found to be abnormal, it indicates that the hepatopancreas of penaeid shrimp begins to have lesions and timely treatment measures need to be taken.

[0024] In another specific embodiment of the present invention, as Figure 2 shown, a camera 4 wirelessly or wiredly connected to the controller is provided on the front side and / or the rear side of the front section of the passage for obtaining the head pictures of penaeid shrimp passing through the passage. When penaeid shrimp have white spot or yellow gill lesions, the symptoms will be concentrated on the head of penaeid shrimp. For white spot disease, obvious white spots can be seen on the cephalothorax carapace and abdominal segment carapace. For yellow gill disease, the gills of penaeid shrimp turn yellow. The cameras on both sides of the passage can timely observe the color change of the head of penaeid shrimp. If the head color of penaeid shrimp is abnormal, timely intervention measures can be taken.

[0025] In specific application, the camera 4 is a spectral camera. Through the spectral camera, the images of both sides and the back of the head of penaeid shrimp can be clearly collected, and based on this, it can be judged whether penaeid shrimp have lesions, playing a warning role, facilitating timely taking of treatment measures, ensuring the timely recovery of penaeid shrimp, and reducing economic losses.

[0026] In a specific embodiment of the present invention, as Figures 1-3As shown, a diseased shrimp isolation mechanism is provided at the outlet end of the channel; both the camera 4 and the diseased shrimp isolation mechanism are wirelessly or wiredly connected to a controller outside the culture pond. Among them, the diseased shrimp isolation mechanism includes a diseased shrimp output pipe 5 and a prawn guiding member 6. The diseased shrimp output pipe 5 is arranged in parallel with the outlet end 101 of the channel at the rear section of the channel; the prawn guiding member 6 is driven by a rotating member 7 and is used to block the inlet side of the outlet end 101 of the channel and the diseased shrimp output pipe 5; the rotating member 7 is wirelessly or wiredly connected to the controller. The rotating member drives the prawn guiding member to rotate at the rear section of the channel, thereby guiding the prawns so that healthy prawns swim out from the outlet end of the channel and diseased shrimps are discharged from the diseased shrimp output pipe. Figure 1 The hollow arrow indicates the swimming direction of the prawns.

[0027] As a preferred structure, as Figure 1 , 3 shown, the prawn guiding member 6 is a row of vertically arranged isolation rods. The ends of the isolation rods are arranged in the chutes of a horizontal sliding rod 8 and can move along the chutes; grids 9 that cooperate with the isolation rods are provided at the top and / or bottom of the rear section of the channel. The number of the isolation rods corresponds one by one to the gaps of the grids 9, and the isolation rods can slide along the gaps of the grids 9; the gaps of the grids 9 are perpendicular to the swimming direction of the prawns; the ends of the sliding rod 8 are fixed on a rotating shaft 12, and the rotating shaft 12 is driven by a rotating member 7. The rotating member 7 can be a micro motor. There are two sliding rods 8, which are respectively arranged at the upper and lower ends of the isolation rods. The micro motor is used to drive the rotating shaft 12 to rotate, and then drive the two sliding rods 8 to swing. The swinging sliding rods 8 drive a row of isolation rods to slide along the gaps of the grids 9 and the chutes of the sliding rods 8 at the same time. The area corresponding to the inlet side of the diseased shrimp output pipe 5 at the rear section of the channel is the diseased shrimp isolation area. When the camera captures healthy prawns, the isolation rods swing to the inlet side of the diseased shrimp isolation area, and the prawns can swim out from the outlet end 101 of the channel; when the camera captures diseased prawns, the isolation rods swing to block in front of the outlet end 101 of the channel, and the diseased shrimps can swim to the diseased shrimp isolation area under the guidance of the isolation rods and enter the diseased shrimp output pipe 5 from the diseased shrimp inlet end 50 and be discharged.

[0028] To further optimize the above technical solution, a lighting lamp is embedded in the side wall of the diseased shrimp inlet end 50 of the diseased shrimp output pipe 5. When the outlet end 101 of the channel is blocked, the diseased shrimp inlet end 50 is opened, and the prawns enter the diseased shrimp output pipe 5 under the guidance of the lighting lamp, avoiding the prawns from hitting the isolation rods in front of the outlet end 101 of the channel by mistake.

[0029] In a specific embodiment of the present invention, as Figure 1 , 2 shown, the side wall of the outlet end of the diseased shrimp output pipe 5 is communicated with a compressed air pipe 10 for supplementing air to the diseased shrimp output pipe 5 and the channel in the box body 1. The compressed air can make the water flow in the diseased shrimp output pipe flow reversely, facilitating the prawns to swim out against the current.

[0030] Further optimize the above technical solution. The diseased shrimp output pipe 5 is a transparent pipe to facilitate lighting. A shrimp net 11 for collecting diseased shrimp is provided at the outlet end of the transparent pipe. The shrimp net can collect the diseased shrimp together, which is convenient for centralized transfer to another pool for targeted intervention treatment.

[0031] During specific production, the open inner cavity 2 is designed as a cylindrical cavity, and the inlet side of the open inner cavity 2 is arranged at the bottom of the box body 1. Among them, the lighting facility 3 is a lighting lamp embedded in the side wall of the open inner cavity 2. This structure facilitates the shrimp to swim towards the open inner cavity of the box body and enter the channel under the guidance of the lighting lamp.

[0032] In summary, the present invention has the advantages of a compact structure and high observation accuracy of shrimp. The box body is placed in the water of the shrimp breeding pond, and the passing shrimp are photographed by the cameras arranged at the top, front and back sides of the channel. The controller analyzes the image data collected by the cameras, and judges the health status of the shrimp by analyzing and identifying the color changes of the heads and backs of the shrimp in the images. The present invention plays a warning role, can timely detect the lesions of the shrimp, is convenient to isolate the diseased shrimp in time, separate them from the breeding pond and promptly carry out symptomatic treatment, can ensure the timely recovery of the shrimp, and reduce economic losses.

[0033] In the above description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed above.
