[0031] Accurately grasping the distribution, growth status, health status, behavioral characteristics, etc. of aquatic animals has become a basic task in intelligent fishery and precision aquaculture. During the process of shrimp farming, shrimp farmers need to manually lift the shrimp net every day to observe the growth, feeding situation, and health status of the shrimp. However, this method is time-consuming and laborious, and limited by the frequency of manual operation, it is difficult to achieve long-term monitoring.

[0032] In view of the above problems, the present utility model provides an auxiliary monitoring device, which realizes long-term monitoring of the growth, feeding situation, and health status of shrimp in a way that replaces manual labor with machinery, and has the characteristics of easy operation and convenient use.

[0033] The technical solutions of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0034] Figure 1 It is a schematic diagram of the overall structure of the auxiliary monitoring device shown in the embodiment of the present utility model.

[0035] As Figure 1 shown, an auxiliary monitoring device provided by an embodiment of the present utility model for shrimp farming includes a floating base 1, a lifting mechanism 2, and a shrimp net 3;

[0036] The lifting mechanism 2 is arranged on the floating base 1, the shrimp net 3 is connected to the lifting mechanism 2, and the lifting mechanism 2 drives the shrimp net 3 to perform reciprocating motion in the vertical direction;

[0037] A controller 4 and a camera module 5 are arranged on the floating base 1. Both the lifting mechanism 2 and the camera module 5 are electrically connected to the controller 4, and the lens of the camera module 5 faces the shrimp net 3.

[0038] The camera module 5 is a mature application of the prior art, and its working principle and structural composition will not be elaborated here.

[0039] Specifically, the controller 4 includes a processor module, a storage module, and a wireless communication module. The storage module is used to store the recognition model of shrimp health information. The first communication end of the processor module is connected to the first communication end of the camera module. The second communication end of the processor module is connected to the first communication end of the storage module. The third communication end of the processor module is connected to the first communication end of the wireless communication module. The second communication end of the wireless communication module is used to establish a communication connection with the cloud server.

[0040] During use, the controller 4 controls the lifting mechanism 2 to drive the shrimp net 3 to move up and down to catch shrimp. The camera module 5 takes pictures of the shrimp in the shrimp net 3 to obtain the health information of the shrimp. The health information of the shrimp is sent to the cloud server through the controller 4. After the cloud server analyzes the health information of the shrimp, it obtains the health analysis result of the shrimp and sends it to the user terminal.

[0041] In this embodiment, when the auxiliary monitoring device interacts with the feeder, it can dynamically adjust the current feeding amount according to the health analysis result to meet the feeding requirement of "small and frequent meals" for shrimp.

[0042] In a preferred embodiment, as Figure 2 shown, the lifting mechanism 2 of the above-mentioned auxiliary monitoring device includes a motor 21, a transmission component 22, and a rope. The motor 21 is arranged on the floating base 1. The rotating shaft of the motor 21 is connected to the transmission component 22. The first end of the rope is connected to the transmission component 22, and the second end is connected to the shrimp net 3.

[0043] Specifically, the motor 21 can be a worm gear motor 21, a stepper motor 21, an electric hoist, or a winch, etc. In a preferred embodiment, the motor 21 can be a worm gear motor 21 and a stepper motor 21. Among them, the worm gear motor 21 has the advantages of a large transmission ratio, self-locking, smooth transmission, large torque transmission, and reversibility. The large transmission ratio of the worm gear can ensure that the shrimp net 3 is pulled smoothly. When the shrimp net 3 is in the water body during the process of the worm gear motor 21 pulling the shrimp net 3 up and down, at this time, the shrimp net 3 is subject to greater water resistance, and the rotating shaft of the worm gear motor 21 can obtain a large torque at a low speed. In addition, the motor 21 can also be a stepper motor 21. A stepper motor 21 is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. Its output angular displacement or linear displacement is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. Therefore, the stepper motor 21 can accurately control the rotation amplitude of the transmission gear, and further accurately position the amplitude of the up and down movement of the shrimp net 3, realize diving at different depths, ensure that the shrimp net 3 can fall into a predetermined position, and enable the shrimp to enter the shrimp net 3 to complete the capture work.

[0044] Further, the transmission assembly 22 of the above-mentioned auxiliary monitoring device includes a driving wheel and a driven wheel. The driving wheel is connected to the rotating shaft of the motor 21. One end of the rope is fixed on the driving wheel, and after the rope winds around the groove of the driven wheel, it is connected to the shrimp net 3.

[0045] Specifically, one end of the rope is fixed on the driving wheel. The driving wheel is connected to the rotating shaft of the motor 21. When the motor 21 rotates, the rope is wound through the driving wheel. The rope is located on the groove of the driven wheel, which can improve the stability of the shrimp net 3 during the lifting and lowering process. The wire diameter range of the rope is between 1.5 mm and 2 mm. In this range, the diameter of the rope after winding around the groove of the driving wheel can be reduced, and the phenomenon of jamming after winding can be avoided. In order to ensure the smooth transmission of the rope, a number of counterweight blocks 6 are arranged on the rope to increase the tension of the rope. In this embodiment, the weight of the counterweight block 6 can be set according to the wire diameter of the rope and the size of the shrimp net, and there is no unique limitation here.

[0046] In practical applications, the shrimp net 3 can be replaced with an existing shrimp-catching device to reduce unnecessary resource waste.

[0047] In a preferred embodiment, the floating base 1 of the above-mentioned auxiliary monitoring device includes a floating platform 11, a bracket 12, and a housing 13. The bracket 12 is connected to the floating platform 11, and the housing 13 is connected to the bracket 12. The lifting mechanism 2, the controller 4, and the camera module 5 are all arranged in the housing 13. The bottom of the housing 13 is provided with a first through hole 131 and a second through hole 132. The lifting mechanism 2 is connected to the shrimp net 3 through the first through hole 131, and the camera module 5 is located in the second through hole 132.

[0048] When in use, the floating base 1 is placed on the water body. The floating base 1 can swim freely on the water body, or an anchoring device can be additionally provided to fix the floating base 1 in a position. The floating platform 11 can be a floating body made of foam or a hollow plastic shell. In this embodiment, the floating platform 11 is a hollow plastic shell. At least three brackets 12 are installed on the hollow plastic shell to form a stable spatial structure. The housing 13 is installed at the other end of the bracket 12. The housing 13 is made of plastic or metal. In this embodiment, the housing 13 is made of stainless steel. The housing 13 includes an upper housing 13 and a lower housing 13. The upper housing 13 and the lower housing 13 can be connected by threads or snap connections. Components such as the lifting mechanism 2, the controller 4, and the camera module 5 are installed on the lower housing 13. A first through hole 131 is opened on the lower housing 13. After the rope is fixed on the driving wheel, the other end passes through the first through hole 131 and is connected to the shrimp net 3. The lens of the camera module 5 is located on the second through hole 132, and the shooting direction of the camera module 5 corresponds to the shrimp net 3.

[0049] When monitoring prawns, the prawn net 3 can be carried out after it is exposed above the water body, or it can be carried out in the water body. Specifically, when the prawn net 3 is exposed above the water body for shooting, information such as the body color of the prawns, the fullness of the digestive tract, and the remaining amount of feed can be obtained; when the prawn net 3 is in the water body, dynamic information of the prawns (for example, the movement speed and movement acceleration of the prawns) or information on the color and turbidity of the water body can be obtained.

[0050] Based on the above specific implementation, in order to improve the shooting effect of the camera module 5 to obtain clear image information, please refer to Figure 3 , the above auxiliary monitoring device further includes a fill light 7, and the fill light 7 is located at the bottom of the housing 13 for providing light source to the camera module 5, and the fill light 7 is electrically connected to the controller 4.

[0051] The fill light 7 includes a box body, a reflector, a circuit board, and a number of LED lamp beads connected to the circuit board. The circuit board, the LED lamp beads, and the reflector are installed on the box body. The LED lamp beads enhance the brightness of the light through the reflector. The shape of the box body can be rectangular, prismatic, spherical, or annular. When the box body is annular, the box body is installed in the second through hole 132, and the camera of the camera module 5 corresponds to the round hole of the annular box body. In this setting, a uniform light output effect can be formed on the outer periphery of the camera module 5 to improve the shooting effect of the camera module 5.

[0052] In a preferred embodiment, as Figure 4 shown, the above auxiliary monitoring device further includes a water quality monitoring component 8 and an air monitoring component 9, and both the water quality monitoring component 8 and the air monitoring component 9 are electrically connected to the controller 4;

[0053] The water quality monitoring component 8 is used to detect the pH value, dissolved oxygen, ammonia nitrogen concentration, and water temperature of the water body;

[0054] The air monitoring component 9 is used to detect the temperature, humidity, and air pressure of the air.

[0055] In practical applications, the growth of prawns is closely related to their surrounding environment. After obtaining the growth, feeding situation, and health status of the prawns through this device, information on the pH value, dissolved oxygen, ammonia nitrogen concentration, and water temperature of the water body is obtained through the water quality monitoring component 8, and the temperature, humidity, and air pressure of the air are detected through the air monitoring component 9. After the controller 4 receives the information sent by the water quality monitoring component 8 and the air monitoring component 9, it feeds it back to the cloud server. After the cloud server analyzes the information, it is sent to the terminal of the prawn farmer to remind the prawn farmer to deal with it in time.

[0056] Further, the water quality monitoring component 8 of the above auxiliary monitoring device includes a pH meter, a dissolved oxygen meter, a nitrogen oxygen analyzer, and a temperature sensor;

[0057] The air monitoring component 9 includes a temperature and humidity sensor and an atmospheric pressure sensor.
