Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of fishway fish observation, and more particularly to a fishway device and a fishway fish observation method based on mixed reality and image recognition. Background Art

[0002] In order to prevent fish from being blocked by buildings such as dams or sluices, it is often necessary to build fishways to help fish migrate. In order to ensure the safety of fish migration in the fishways and conduct research on fish, it is often necessary to observe fish in the fishways. The Chinese invention patent with application number CN202211012021.6 discloses a fishway fish observation method based on mixed reality and image recognition. It uses image recognition and mixed reality technology to observe fish in fishways in real time, and obtain the position, number, and migration habits of migratory fish in the fishways in real time. This patent provides a new holographic, full-line, and real-time fish observation method, which is of great help in studying fish migration and can better protect the fish ecology at water conservancy hubs.

[0003] According to the technical scheme for observing fish in the fishway disclosed in the patent, there are several problems. On the one hand, when observing the fish in the fishway, it is often impossible to observe the fish in person, and it is impossible to adjust the equipment in the fishway according to the problems or obstacles encountered in the fish migration process, so that different fish can smoothly pass through the fishway for migration. On the other hand, when encountering a large number of fish for migration, it is easy to cause congestion in the fishway, and the fish in the fishway are easy to be unable to swim due to long-term physical exhaustion. On the one hand, after the fish migration operation is completed, a certain amount of fish remains are likely to remain in the fishway, which will cause the breeding of pathogens and is not conducive to ensuring the safety of the next fish migration work. On the other hand, when the fish are driven away from the buffer zone, it is easy for the fish to be squeezed by the movable plate and injured or even killed, which is not conducive to ensuring the safe expulsion of the fish. In addition, when the electromagnet is repeatedly switched on and off for safe expulsion, it is easy to cause the switch to fail and be damaged, which is not conducive to ensuring the working stability of the electromagnet.

[0039] On the other hand, the present disclosure provides a method for observing fish in a fishway based on mixed reality and image recognition, the method comprising:

[0040] The images inside the fishway device as described above collected by the collection unit are three-dimensionally modeled, and the modeled images are transmitted to the display device and the VR device;

[0041] Check whether the monitoring screen of the acquisition unit fully covers the fishway. If not, adjust the position of the acquisition unit so that the monitoring screen fully covers the fishway, and check that no screen jumps or monitoring blind spots occur when the screen is moved;

[0042] During the fish migration season, the data collection unit is turned on to conduct real-time detection of the fish schools in the fishway, and obtain the school size, individual size and swimming speed of the fish in the fishway in real time, so as to take corresponding operations to adjust the fishway and help the fish schools migrate.

[0043] Optionally, before three-dimensionally modeling the fishway device images collected by the collection unit, the method further includes: modeling the fishway, and calculating the installation positions and numbers of the collection units according to the modeling results, so as to perform omnidirectional image collection of the entire fishway;

[0044] According to the calculation results, the collection unit is installed at the position corresponding to the fishway.

[0045] Optionally, the real-time acquisition of the size of the school of fish, the size of the individual fish, and the swimming speed of the fish in the fishway so as to take corresponding operations to adjust the fishway and help the school of fish to migrate includes:

[0046] During the migration season, the collection unit collects video inside the fishway;

[0047] According to the video of the school of fish in the fishway collected by the collection unit, the size of the school of fish in the fishway, the size of the individual fish, and the swimming speed information are obtained. When the fishway device is provided with an adjustment component, the size of the fish hole is adjusted by controlling the adjustment component to adjust the size of the water flow in the fishway;

[0048] The fish school density is calculated based on the size of the fish school. When the fish school density is greater than the preset density, the fish school in the fishway is relatively crowded. At this time, some or all of the buffer tank gates are opened to allow part of the fish school to swim into the buffer tank for temporary stay.

[0049] When the fish school stays in the buffer tank for longer than a preset time and part of the buffer tank is opened, the gates of part of the buffer tanks adjacent to the opened buffer tanks are opened, and the driving components in the previously opened buffer tanks are activated to drive the fish school in the previously opened buffer tanks into the fishway, and the previously opened buffer tanks are closed;

[0050] When the fish density in the fishway is less than the preset density, the fish in the fishway is relatively loose, and the drive component of the opened buffer box is started to drive the fish in the buffer box into the fishway, and the buffer box gate is closed.

[0051] Optionally, the real-time acquisition of the school size, individual size and swimming speed of fish in the fishway so as to take corresponding operations to adjust the fishway to help the fish migrate also includes: after the fish migration season has passed, based on the fish school information in the fishway collected by the collection unit, checking whether there are preset fish in the fishway, if there are preset fish, locating them to help them migrate upstream, if there are no preset fish, fully opening the fish hole to flush the fish downstream.

[0052] The beneficial effects of the embodiments of the present disclosure are:

[0053] The fishway device of the disclosed embodiment has a simple structure, which is conducive to helping fish migrate. The number of fish holes on the partition plate can be increased so that fish can smoothly pass through the fish holes and swim smoothly in the fishway, and the fish holes can be opened too wide to avoid excessive water flow, thereby preventing fish from being unable to pass through the water flow and swim upstream. The buffer box can also provide a temporary rest for fish in the fishway, avoiding the fish from consuming their physical strength to avoid being washed away by the water flow, and can alleviate the crowded situation of fish in the fishway.

DETAILED DESCRIPTION

[0060] In order to make the purpose, technical solution and advantages of the embodiment of the present disclosure more clear, the embodiment of the present disclosure is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described here are only used to explain the embodiment of the present disclosure and are not used to limit the embodiment of the present disclosure.

[0061] like Figure 1 As shown, an embodiment of the present disclosure proposes a fishway device, which includes: a fishway 1, wherein at least one partition plate (not marked in the figure) is arranged inside the fishway, and the partition plate divides the inside of the fishway into a plurality of fish passing areas, and each partition plate and the top and bottom walls of the fishway are provided with a plurality of fish passing holes 2; a collecting unit 3, which has a plurality of units and is arranged on the inner wall of the fishway, and the collecting range covers the entire area inside the fishway, so as to collect information of fish schools in the fishway; a buffer box 4, which is arranged in the fishway 1 and is connected to the corresponding fish passing area, and the buffer box 4 has a accommodating cavity for temporarily retaining fish schools; a driving component, which is arranged in the buffer box 4 and is used to drive the fish schools in the buffer box 4.

[0062] The fishway of the disclosed embodiment is set in an area with a slope for fish migration; the partition is to block excessive water flow to prevent too much water from flowing down from upstream. Different numbers of partitions can be installed according to the on-site environment. The distance between two adjacent partitions can be equidistant or unequal. Multiple partitions are installed to form a fish passing area between two adjacent partitions, or between the partition and the top wall or bottom wall of the fishway. The buffer box (area) can also be constructed according to the actual conditions on site. In practice, it can be set on one side of the fishway or distributed on both sides of the fishway. One or more buffer boxes can be set. The position and number of buffer boxes can be adjusted according to the actual situation. The distance between two adjacent buffer boxes can be equidistant or unequal. Preferably, a buffer box is set every other fish passing area in the fishway.

[0063] The method for determining the installation position and number of acquisition units includes: 3D modeling of the fishway, and calculating the installation position and number of cameras based on the 3D model of the fishway to perform all-round image acquisition of the entire fishway; installing acquisition units at the corresponding positions of the fishway according to the calculation results, and the acquisition units can be high-definition cameras and other equipment. The specific installation position and number of acquisition units are obtained after calculation based on the three-dimensional 3D modeling of the fishway, which can reduce the number of installed acquisition units while ensuring full coverage of the required observation area in the fishway and reduce the manpower adjustment and inspection of the observation angle of the acquisition unit. The fish school swims against the current in the fishway. Generally, the fishway has a long distance. Buffer boxes are set at intervals on the fishway so that the fish school can rest in the buffer box to avoid being washed downstream when resting. The number and installation positions of the buffer boxes can be set according to the actual length of the fishway. One or several fish passing areas can be spaced apart along the length of the fishway, and a buffer box can be evenly or unevenly set. The buffer box is connected to the corresponding fish passing area. An opening needs to be set on the side wall of the fishway. In order to facilitate the control of the application of the buffer box, a gate 5 is also set at the opening, and the gate is used to open or close the opening.

[0064] In the disclosed embodiment, the partition plate can block part of the upstream water flow, thereby reducing the water flow rate and reducing the resistance of fish migration. The partition plate is used to slow down the speed of water flowing downward through the fishway. A plurality of fish holes are provided on the partition plate so that the fish will only be impacted by the faster water flow when passing through the fish holes, while the water flow speed in the air cylinder area of ​​the fishway is reduced, which is convenient for the fish to swim upstream; the number of fish holes is set according to the drop in the fishway to reduce the water flow speed and ensure that the fish can migrate smoothly. The acquisition unit can observe the situation of the fish school in the fishway in real time, obtain the information of the fish school, and provide corresponding assistance for the migration of the fish school in a timely manner. The buffer box can provide a temporary place for the fish school in the fishway to stay, so that part of the fish school in the fishway can stay in the buffer zone temporarily, which can not only provide a rest area for the fish to avoid the fish from consuming physical energy to avoid being washed away by the water flow, but also alleviate the crowded situation of the fish school in the fishway. In the disclosed embodiment, the driving component can be controlled in a timely manner to drive the fish in the buffer box according to the fish information obtained by the collection unit, so as to prevent the fish from staying in the buffer box for a long time, and effectively avoid the fish from staying in the buffer zone for too long and mistakenly thinking that they have migrated to the destination, and then breeding, staying for food, overwintering, etc. in the buffer zone.

[0065] As a specific example of the device, the device also includes at least one adjustment component (not shown in the figure), which is arranged on the corresponding partition plate, and the adjustment component includes: a plurality of gate plates (not shown in the figure), which are respectively arranged on each fish hole, for adjusting the size of the fish hole and the number of openings.

[0066] In the device of the embodiment of the present disclosure, an adjustment component is provided on each partition plate, which is used to adjust the size of the fish holes and the number of fish holes opened, so as to adjust the size of the water flow downstream of the partition plate. The position and number of the fish holes can be set according to actual conditions. The fish holes are evenly arranged in three rows along the height direction of the fishway, with multiple fish holes in each row, and all are close to one side of the fishway. Each partition plate is provided with multiple fish holes, and the adjustment device on the fish holes is similar to an electric gate mechanism, which can adjust the opening of the fish holes and open a certain number of fish holes as needed, thereby adjusting the size and number of the fish holes; specifically, the size of the fish holes can be adjusted by controlling the moving position of the gate, and the number of fish holes can also be adjusted by opening and closing different numbers of gates.

[0067] The regulating assembly is similar to a gate structure, with multiple gate plates arranged on the inner side of the gate. The gate plates move on the inner side of the opening, just like an elevator door moves left and right, and can also move up and down like a sluice gate. Figure 2 A partition slot in the gate represents a gate unit.

[0068] The disclosed embodiment obtains information such as the school size, individual size, and swimming speed of the fish in the fishway based on the information of the fish school in the fishway collected by the collection unit, and controls the size and number of the fish holes opened according to the school size, individual size, and swimming speed of the fish in the fishway, thereby adjusting the size of the water flow downstream of the partition plate so that the fish can smoothly pass through the fish holes and swim smoothly in the fishway, and avoids excessive water flow due to too large and too many fish holes being opened, thereby avoiding the situation where the fish cannot pass through the water flow and cannot swim upstream.

[0069] As a specific example of a driving component, a supporting frame is provided at the connecting port between the buffer box and the fishway, and the supporting frame is provided with a gate that can open and close the connecting port; the driving component includes: a first motor 6, which is arranged on the outer wall of the buffer box 4 away from the fishway 1; a screw rod 7, which is arranged inside the buffer box 4, one end of which is keyed to the output shaft of the first motor 6, and the other end of which is rotatably arranged on the supporting frame; a flap 8, which is arranged in the buffer box 4 and can be movably sleeved on the screw rod 7, does not rotate with the screw rod, and matches the shape inside the buffer box 4; a vibration component, one end of which is sleeved on the screw rod 7 and threadedly connected to the screw rod, and the other end is connected to the flap 8, when the first motor 6 is started, it drives the screw rod 7 to rotate, and the flap 8 and the buffer box 4 do not rotate, thereby making the vibration component move along the screw rod 7 to drive the flap 8 to move in the buffer box 4, and make the flap 8 vibrate, so as to achieve driving the fish in the buffer box.

[0070] The opening of the fishway in the disclosed embodiment is provided with a support frame, and the support frame is provided with a gate that can open and close the connecting port; the first motor is fixed to the central area of ​​the outer wall of the buffer box away from the fishway, the output shaft of the first motor penetrates the side wall of the buffer box and is fixedly connected to one end of the screw rod, and the other end of the screw rod is rotatably provided in the central area of ​​the support frame through a bearing, so that the first motor can drive the screw rod to rotate. The buffer box is a non-cylindrical shape, and the buffer box can be a rectangular box structure with an opening on one side, which is connected to the opening of the side wall of the fishway to form a connecting port. The flap can be movably sleeved on the outside of the screw rod, and the flap is a square plate structure that matches the buffer box. The shape of the flap matches the internal shape of the buffer box, and each edge of the flap is gap-matched with the corresponding edge of the buffer box, and the flap itself will not rotate around the screw rod; the flap can be provided with a plurality of small holes to facilitate the flow of water, prevent fish from swimming through, and facilitate the movement of the flap. The vibration component is sleeved on the screw rod and is threadedly connected to the screw rod. One end of the vibration component is fixedly connected to the movable plate, and the square movable plate is engaged with the buffer box. The first motor is started and the screw rod is rotated. The movable plate is engaged with the side walls of the buffer box on all sides and does not rotate. The vibration component is fixedly connected to the movable plate and is threadedly connected to the screw rod, so that the vibration component rotates along the screw rod, thereby driving the movable plate to move in the buffer box to adjust the size of the buffer zone, thereby achieving the effect of driving away the school of fish. In the process of driving the movable plate to move, the vibration component also causes the movable plate to vibrate. In this way, the vibration of the movable plate is used to generate shock waves to drive away the school of fish, thereby preventing the movable plate from directly hitting or even squeezing the school of fish, ensuring that the school of fish is safely driven away from the buffer zone, and preventing the school of fish from being injured or even killed during the driving process.

[0071] As an example of a vibration component, the vibration component includes: a sleeve 14, a central area of ​​which is provided with a sleeve threadedly connected to the screw rod 7 and at least two evenly divided chambers are provided around the sleeve; a vibration mechanism, having at least two, which are respectively provided in the corresponding chambers in the sleeve; the vibration mechanism includes: an electromagnet 15, which is movably provided in a chamber in the sleeve 14; a guide rod 16, which is passed through the sleeve 14, one end of which is connected to the electromagnet 15, and the other end extends out of the sleeve 14 and is connected to the flap 8; a first elastic member 17, one end of which is connected to the inner side wall of the sleeve 14 close to the flap 8, and the other end is connected to the electromagnet 15, wherein the inner side wall of the chamber close to the flap 8 is made of iron material or the inner side wall of the chamber close to the flap is provided with an iron sheet; a locking assembly, which is provided on the side of the chamber away from the first elastic member 17, connected to the electromagnet 15, and is used to lock or unlock the electromagnet 15.

[0072] In the embodiment of the present disclosure, the ferrule has at least two equally divided chambers, a sleeve is provided in the central area of ​​the ferrule, the sleeve is threadedly connected to the screw, and each chamber is provided with a vibration mechanism. The two chambers are symmetrically distributed on both sides of the screw, and the vibration mechanism is arranged in the chamber of the ferrule, which can maintain the stability of the driving assembly; if there are two vibration assemblies, they are symmetrically distributed on both sides of the ferrule, and the symmetrically distributed vibration mechanism is used to avoid deflection when pushing the flap, and if there are multiple chambers and vibration assemblies, they are evenly distributed around the screw. The first elastic member can be an elastic member such as a spring. The locking assembly is used to lock or unlock the electromagnet. When the screw rotates and drives the ferrule to move away from the fishway, the ferrule pushes the electromagnet through the first elastic member, the electromagnet compresses the first elastic member and drives the flap to move away from the fishway, that is, to the right, and the electromagnet pulls the locking assembly, so that the locking assembly is in an unlocked state, the electromagnet will not be energized, and the flap will not vibrate. When the lead screw rotates and drives the ferrule to move toward the fishway, the electromagnet in the ferrule is energized to generate magnetic force, and the electromagnet and the inner wall of the chamber close to the flap generate suction and move closer to the inner wall in the chamber, that is, the electromagnet moves toward the fishway and quickly pushes the flap toward the fishway for a short distance, while pulling the locking assembly toward the fishway until the locking assembly is unlocked, the electromagnet loses power, the magnetic force disappears, and the flap vibrates under the action of the first elastic member, and then the ferrule continues to move toward the fishway, so that the locking assembly is re-locked, the electromagnet is re-energized, and the electromagnet moves toward the fishway again, and the cycle is repeated, so that the flap moves toward the fishway while vibrating the flap to prevent the flap from directly hitting or even squeezing the fish, thereby achieving the purpose of driving the fish out of the buffer box.

[0073] As a specific example of a locking assembly, two slots are symmetrically provided on the side wall of the chamber, and the locking assembly includes: a pull rod 18, one end of which is connected to the electromagnet 15, and the other end is provided with a circular plate; a ring 19, which is sleeved on the circular plate, and the ring 19 is in contact with the side wall of the chamber; a first electrode sheet 20, which is symmetrically provided on both sides of the outer wall of the ring 19, corresponding to the side wall of the chamber provided with the slots; a second electrode sheet 21, which has two, which are respectively provided in the corresponding slots, and the second electrode sheet 21 is electrically connected to the electromagnet 15. When the second electrode sheet 21 is matched and connected with the corresponding first electrode sheet 20, the electromagnet 15 is energized.

[0074] In the embodiment of the present disclosure, a second elastic member may be further provided in the slot, and the second electrode sheet is connected to the corresponding slot via the corresponding second elastic member, that is, one end of the second elastic member is connected to the bottom wall of the slot, and the other end is connected to the second electrode sheet. Figure 3In the embodiment of the present invention, the width of the inner side of the sleeve is greater than the width of the circular plate, so that the sleeve can be sleeved on the circular plate, and the sleeve can be moved on the outer side of the circular plate, so as to avoid the electromagnet being powered off and the spring pushing the electromagnet, and the electromagnet driving the electrode sheet 1 on the sleeve to contact the electrode sheet 2 through the pull rod, thereby avoiding the electromagnet from excessively performing power-on and power-off operations. In the embodiment of the present invention, the chamber is provided with protrusions inwardly away from the two side walls of the fishway, and the sleeve wall is thin, so it is not convenient to directly set the slots for installing the second elastic member and the second electrode sheet, so the inner side wall of the sleeve can be provided with the protrusions, and the slots are opened in the protrusions. The circular plate sleeve of the pull rod is provided with a sleeve, and the first electrode sheet is symmetrically arranged on both sides of the outer wall of the sleeve, respectively corresponding to the slots. When the pull rod moves, it can drive the first electrode sheet of the sleeve to contact the corresponding second electrode sheet. The sleeve can be a non-conductive hard material, such as acrylic, plastic, etc.

[0075] Specifically, when the lead screw drives the ferrule to move away from the fishway, that is, to the right, if the electromagnet is energized, the attraction of the iron material on the left and the movement of the ferrule to the right under the pulling force of the first elastic member will cause the electromagnet to generate a pulling force to the left and the power will be cut off. The ferrule pushes the electromagnet through the spring, and the electromagnet compresses the spring and drives the flap to move to the right. The electromagnet drives the ring and the first electrode sheet to move to the left side of the second electrode sheet through the pull rod, keeping the first electrode sheet and the second electrode sheet out of contact at all times, so that the electromagnet will not be energized and the flap will not vibrate. When driving away the fish in the buffer zone, the first motor 6 drives the sleeve 14 to the fishway direction, that is, to the left, through the screw rod 7, and the electromagnet 15 in the sleeve 14 is energized to generate magnetic force. Due to the attraction of the iron material on the left side of the chamber, the electromagnet 15 moves closer to the left end of the sleeve 14 and quickly pushes the flap 8 to the left a short distance. At the same time, the electromagnet 15 drives the pull rod 18 to move, and the pull rod 18 pushes the collar 19 to move to the left, so that the first electrode sheet 20 is separated from the second electrode sheet 21. The electromagnet 15 is de-energized, and the first spring 17 pushes the electromagnet 15 to the left, and pulls the flap 8 to the left a short distance through the connecting rod 16, so that the sleeve 14 is on the screw rod 7. When the pull rod 18 moves to the left, the flap 8 is driven to vibrate continuously, and then the vibration of the flap 8 is used to generate shock waves to drive away the fish school, so as to prevent the flap 8 from directly hitting or even squeezing the fish school, and ensure that the fish school is safely driven away from the buffer zone, and prevent the fish school from being injured or even killed. When the pull rod 18 drives the ring 19 to move back and forth, the second electrode sheet 21 maintains the clamping force with the first electrode sheet 20 under the elastic force of the second spring 22, and even if the second electrode sheet 21 and the first electrode sheet 20 are worn, it can ensure that the second electrode sheet 21 and the first electrode sheet 20 are fully in contact, and ensure the intermittent power supply to the electromagnet 15, and then ensure the stable operation of the electromagnet 15. Then, the sleeve continues to move to the left under the action of the screw rod, and during the vibration of the first elastic member, until the first electrode sheet and the second electrode sheet are engaged again, the electromagnet is powered on again, and the flap moves in a cycle.

[0076] As a specific example of the device, the device further includes a cleaning component, which is disposed at an upstream end of the fishway and is used to put a cleaning agent into the fishway.

[0077] In the disclosed embodiment, a cleaning agent is added into the fishway to disinfect and sterilize the fishway.

[0078] As a specific example of the cleaning assembly, the cleaning assembly includes: a medicine box 9, an outer side wall arranged upstream of the fishway, and a box cover 10 that can open and close the medicine box opening. ，The medicine box 9 is used to store cleaning agent; the second motor 11 is arranged on an outer wall of the medicine box; the rotating rod 12 is arranged in the medicine box 9, and one end of the rotating rod 12 is keyed to the output shaft of the second motor passing through the side wall of the medicine box; the valve 13 is arranged at the connecting port between the medicine box and the side wall of the fishway to open or close the connecting port.

[0079] The box cover of the embodiment of the present invention can be located above the water level, and the two ends of the fishway are respectively installed at the upstream and downstream of the river, so that the fishway is inclined, so that the top of the fishway is inclined upward. The medicine box and the side wall of the fishway are provided with a connecting port, and a disinfectant that can be quickly degraded is added into the medicine box through the connecting port. The second motor drives the rotating rod to mix the disinfectant evenly, and the valve is opened to release the disinfectant into the inner side of the fishway to disinfect and sterilize the fishway.

[0080] As a specific example of the device, the device also includes: a control switch group, which is electrically connected to the first motor, the second motor and the first electrode sheet respectively to control the start and stop of the first motor and the second motor, and control the power on and off of the first electrode sheet.

[0081] The control switch group of the embodiment of the present disclosure may also be replaced by other control units to implement corresponding control device functions.

[0082] like Figure 4 As shown, another aspect of the present disclosure provides a method for observing fish in a fishway based on mixed reality and image recognition, the method comprising:

[0083] Step S10, three-dimensionally modeling the images inside the fishway device as described above collected by the collection unit, and transmitting the modeled images to a display device and a VR device;

[0084] Step S20, checking whether the monitoring screen of the acquisition unit fully covers the fishway, if not, adjusting the position of the acquisition unit so that the monitoring screen fully covers the fishway, and checking that no screen jumps or monitoring blind spots occur when the screen is moved;

[0085] Step S30: During the fish migration season, the data acquisition unit is turned on to perform real-time detection of the fish schools in the fishway, and the size, individual size and swimming speed of the fish in the fishway are obtained in real time, so as to take corresponding operations to control the fishway and help the fish schools migrate.

[0086] In the disclosed embodiments, the display device is generally a monitor, which displays the images captured by the acquisition unit. The VR device is generally VR glasses or a VR headset, which can transmit the images captured by the acquisition unit (camera) to the VR device. Both of them perform image transmission, but the display method is different. One host can be shared, or two hosts can work independently, which is not limited here.

[0087] Preferably, before three-dimensionally modeling the fishway device images collected by the collection unit, the method further comprises: modeling the fishway, and calculating the installation positions and numbers of the collection units according to the modeling results, so as to collect all-round images of the fishway as a whole;

[0088] According to the calculation results, the collection unit is installed at the position corresponding to the fishway.

[0089] As a specific example of a fish observation method in a fishway based on mixed reality and image recognition, the real-time acquisition of the size of the school of fish, the size of the individual fish, and the swimming speed of the fish in the fishway so as to take corresponding operations to control the fishway and help the school of fish migrate includes:

[0090] Step S31: During the migration season, the collection unit collects the video in the fishway. The fishway is closed at other times, so no collection work is required.

[0091] Step S32, based on the fish school video in the fishway collected by the collection unit, obtain information such as the size of the fish school in the fishway, the size of the individual fish, the swimming speed, etc. When the fishway device is provided with an adjustment component, the size and number of the fish holes are adjusted by controlling the adjustment component to adjust the size of the water flow in the fishway.

[0092] Step S33, the fish density is calculated according to the fish size and the fishway size. When the fish density is greater than the preset density, the fish in the fishway is relatively crowded. At this time, if a gate is provided, the buffer box gate can be opened to open part or all of the buffer box, so that part of the fish swims into the buffer box for temporary stay.

[0093] The disclosed embodiment can open some or all of the buffer boxes near the more crowded fish schools in step S33. Specifically, the number and position of the buffer boxes opened depends on the number and position of the fish schools in the fishway. The buffer boxes are opened mainly to prevent the fish schools from being congested in the fishway and needing to rely on swimming for a long time to overcome the water flow, thereby avoiding excessive physical exertion of the fish schools.

[0094] Step S34: When the fish school stays in the buffer box for longer than a preset time and a portion of the buffer box is opened, the gate of the buffer box adjacent to the partially opened buffer box is opened, the driving component in the previously opened buffer box is started, the fish school in the previously opened partial buffer box is driven into the fishway, and the gate of the previously opened buffer box is closed.

[0095] The order of opening can be determined according to the specific situation. The principle is to open the buffer box closest to the fish school's staying position to facilitate the fish school to swim to the buffer box to rest. If the fish school stays in the buffer box for too long, open the adjacent buffer box. Or, based on the distribution of fish schools in the fishway, still open the buffer box closest to the fish school's staying position.

[0096] Step S35, when the fish density in the fishway is less than the preset density, the fish in the fishway is relatively loose, then the drive assembly of the opened buffer box is started to drive the fish in the buffer box into the fishway, and the buffer box gate is closed.

[0097] The method further includes: after the fish migration season has passed, based on the fish school information in the fishway collected by the collection unit, checking whether there are preset fish in the fishway, if there are preset fish, locating them to help them migrate upstream, if there are no preset fish, fully opening the fish hole to flush the fish downstream.

[0098] The disclosed embodiment is also provided with identification of precious fish and corresponding measures. Precious fish can be set according to actual conditions, and precious fish identification models can be trained according to images of precious fish. For example, precious fish are Huaiwang fish, anti-wave fish, shad, red-scaled fish, etc. Images of precious fish that may appear in the area are input into the image recognizer as a training set. When the image recognizer is used to identify whether there are these precious fish in the fishway, it can automatically check whether there are preset fish in the fishway. Existing face recognition and object recognition can realize these functions. The above-mentioned data transmission work can be realized through wireless network or optical network, which is not limited here.

[0099] By adopting the above technical solution disclosed in the embodiment of the present disclosure, the following beneficial effects are obtained:

[0100] 1. The fish observation method in fishways based on mixed reality and image recognition models the fishways and calculates the installation positions and number of cameras based on the modeling, so as to achieve all-round observation of the entire fishway without interference from the buildings and equipment in the fishway; according to the calculation results, high-definition cameras are installed at the corresponding positions of the fishways, and the images taken by the cameras are three-dimensionally modeled, and the modeled images are transmitted to the display device and VR device at the same time; personnel and artificial intelligence are used to check whether the monitoring images of the cameras can fully cover the fishway, and to ensure that there will be no picture jumps when moving the images and to avoid monitoring blind spots. Personnel can feel immersive when wearing VR equipment and can move throughout the fishway; the fish hole control equipment in the fishway is connected to the intelligent system, And connect the input terminal of the intelligent system with the VR device; the camera works to transmit the swimming images of fish in the fishway to the display device and VR device, so that personnel and artificial intelligence can observe the type of fish, school size, individual size, swimming speed and other information in real time; personnel and artificial intelligence detect the school of fish in real time through display devices or VR devices, and the VR device makes it convenient for personnel to observe the fish in an immersive way, and at the same time can accurately understand the problems encountered by fish during migration; the adjustment device of the fish hole is controlled according to the school size, individual size, swimming speed and other factors of the fish, so that the fish can swim smoothly through the fish hole in the fishway, and avoid excessive water flow due to the fish hole being opened too large, thereby avoiding the situation where the fish cannot pass through the water flow and swim upstream.

[0101] 2. The fish observation method for fishways based on mixed reality and image recognition observes the migratory status of fishes when working. When the number of fishes is large and the fish schools in the fishway are crowded, the gate on the buffer zone is opened so that some fish schools can temporarily stay in the buffer zone, which can provide a rest area for fishes and prevent them from consuming their physical strength to avoid being washed away by the water flow, and can also alleviate the crowded situation of fish schools in the fishway. When the number of fish schools in the fishway decreases, the motor pushes the fishway under the flap through the screw rod to drive the fish schools in the buffer zone to the inside of the fishway, and close the gate on the buffer zone. When the number of fish schools in the fishway remains high for a long time, the gate of the adjacent buffer zone is opened, and the fish schools in the previously opened buffer zone are driven to the inside of the fishway, and the buffer zone is closed, effectively preventing fishes from staying in the buffer zone for too long and mistakenly thinking that they have migrated to their destination, and performing behaviors such as breeding, staying for food, and overwintering in the buffer zone, thereby ensuring that fishes can safely migrate to their habitats and ensuring the safety of fish migration.

[0102] 3. When the fish observation method in the fishway based on mixed reality and image recognition is working, after the fish migration season has passed, the fishway is checked by artificial intelligence and personnel using display devices or VR devices to prevent a small number of fish from remaining in the fishway and failing to migrate to the destination. By identifying the type of fish, check whether there are precious fish. If there are precious fish, locate them to help them migrate upstream. If there are no precious fish, open the fish hole completely and flush the fish downstream. Then close the fishway, stir the disinfectant in the medicine box evenly through the second motor and the rotating rod, and pass it into the inner side of the fishway through the valve. The first motor drives the flap to move back and forth through the screw rod to agitate the water, which can not only clean the buffer zone, but also fully contact the disinfectant with the fishway and the buffer zone, clean and disinfect the fishway, avoid the breeding of pathogens in the fishway, and ensure the safety of fish migrating through the fishway in the next migration season.

[0103] 4. When the fish observation method for fish passage based on mixed reality and image recognition is working, when driving away the fish in the buffer zone, the motor 1 drives the ferrule to move to the left through the screw rod, the electromagnet in the ferrule is energized to generate magnetic force, the electromagnet moves close to the left end of the ferrule, and quickly pushes the flap to the left a short distance, and at the same time, the electromagnet drives the pull rod to move, and the pull rod pushes the left side of the ring, so that the electrode sheet 1 is separated from the electrode sheet 2, the electromagnet is powered off, and the spring 1 pushes the electromagnet to the right, and pulls the flap to the left a short distance through the connecting rod, so that the ferrule moves to the left on the screw rod. When moving, it drives the flap to vibrate continuously, and then uses the vibration of the flap to generate shock waves to drive away the fish school, so as to prevent the flap from directly hitting or even squeezing the fish school, and ensure that the fish school is safely driven away from the buffer zone to prevent the fish school from being injured or even killed. When the pull rod drives the ring to move back and forth, the electrode sheet 2 maintains the clamping force with the electrode sheet 1 under the elastic force of the spring 2. Even if the electrode sheet 2 and the electrode sheet 1 are worn, it can ensure that the electrode sheet 2 and the electrode sheet 1 are in full contact, thereby ensuring the intermittent power supply to the electromagnet, and thus ensuring the stable operation of the electromagnet.

[0104] The following is a detailed description of other fish observation methods in fishways, such as Figure 5 As shown, the following steps are included:

[0105] S1. Modeling the fishway 1, and calculating the installation position and number of the cameras 3 based on the modeling, so as to achieve all-round observation of the entire fishway 1 without being disturbed by the buildings and equipment in the fishway 1;

[0107] S3. Check whether the surveillance images of the camera can fully cover the fishway 1 through personnel and artificial intelligence, and ensure that there will be no picture jumps when moving the picture and avoid blind spots in the surveillance. When wearing VR equipment, personnel can feel immersed in the scene and can move in the entire fishway 1;

[0108] S4. The fish hole 2 control device in the fishway 1 is connected to the intelligent system, and the input terminal of the intelligent system is connected to the VR device;

[0109] S5. Camera 3 works and transmits the fish swimming images in fishway 1 to the display device and VR device. Humans and artificial intelligence can observe the fish species, school size, individual size, swimming speed and other information in real time.

[0110] S6. Personnel and artificial intelligence detect fish schools in real time through display devices or VR devices. VR devices enable personnel to observe fish in an immersive way and accurately understand the problems encountered by fish during migration;

[0111] S7. According to the size of the fish school, the size of the individual, the swimming speed, etc. of the fish, the adjustment device of the fish hole 2 is controlled so that the fish can smoothly pass through the fish hole 2 and swim smoothly in the fishway 1, and avoid the excessive water flow caused by the fish hole 2 being opened too large, thereby avoiding the fish from being unable to pass through the water flow to swim upstream;

[0112] S8. Observe the migration status of fish. When the number of fish is large and the fish school in the fishway 1 is crowded, open the buffer zone 4 so that some fish can temporarily stay in the buffer zone 4. This can provide a rest area for the fish to avoid the fish from consuming their energy to avoid being washed away by the water flow, and can also alleviate the crowded situation of the fish school in the fishway 1.

[0113] S9. When the number of fish in the fishway 1 decreases, the fish in the buffer zone 4 are driven to the inner side of the fishway 1 and the buffer zone 4 is closed;

[0114] S10. When the number of fish in the fishway 1 remains high for a long time, the adjacent buffer zone 4 is opened, and the fish in the previously opened buffer zone 4 are driven to the inner side of the fishway 1, and the buffer zone 4 is closed, so as to effectively prevent the fish from staying in the buffer zone 4 for too long and mistakenly thinking that the fish have migrated to their destination, and the fish from breeding, staying for food, overwintering, etc. in the buffer zone 4;

[0115] S11. When the fish migration season is over, artificial intelligence and personnel use display devices or VR devices to check the fishway 1 to prevent a small number of fish from remaining in the fishway 1 and failing to migrate to the destination. By identifying the types of fish, check whether there are precious fish. If there are precious fish, locate them to help them migrate upstream. If there are no precious fish, fully open the fish hole 2 and flush the fish downstream.
