Description

Technical Field

[0001] The present invention relates to the field of ecological assessment, and in particular to a data acquisition system and method for ecological assessment of artificial fish reefs. Background Art

[0002] Artificial reefs are structures artificially placed in waters to attract fish and other aquatic organisms. The principle of their attracting effect is to create a habitat suitable for fish survival based on the tropism of fish and other aquatic organisms and the flow field effect, bait effect and enemy shielding effect generated after the placement of reefs, and ultimately achieve the purpose of protecting and increasing fish and other aquatic biological resources. At present, artificial reefs are widely used to improve the habitat of aquatic organisms, provide fish with places for foraging, reproduction, and avoiding enemies, so as to achieve the purpose of protecting and increasing resources and increasing catches.

[0003] At present, the research on the biological attraction effect of artificial reefs is mainly focused on swimming organisms such as fish in the marine area. By comparing and analyzing the changes of swimming animals, large benthic animals and seaweed in the reef area before and after, the ecological protection effect of artificial reefs can be reflected.

[0004] In the prior art, for example, patent publication number CN220798403U discloses an underwater identification device for coral reef fish, which connects a camera through a retractable line under the buoy base, and sets a solar panel on the buoy base to achieve long-term power supply. However, when the camera is underwater for a long time, microorganisms, algae and sediments will gradually accumulate on its lens, which will affect the image clarity. In the prior art, a scraping device is often designed for the lens, but in ecological research, the microorganisms, algae and sediments on the lens are also research materials that can feedback underwater ecological changes. Therefore, a data acquisition system and method for artificial reef ecological evaluation is needed, which can not only reduce the impact of underwater camera imaging clarity, but also collect microorganisms, algae and sediments on the camera lens. Summary of the invention

[0005] To solve the above problems, the present invention provides a data collection system and method for artificial reef ecological assessment, which can reduce the impact on the imaging clarity of underwater cameras and can also collect microorganisms, algae and sediments on the camera lens.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a data acquisition system for artificial reef ecological assessment comprises:

[0007] Underwater acquisition module: used to collect underwater ecological parameters. The underwater acquisition module includes several optical collectors, which are used for spectrum detection and image acquisition respectively. The optical collectors all include outer lenses, which are used to provide a channel for light to enter and exit the optical collector. The outer lenses are covered with several layers of transparent films. The optical collectors are all provided with a transparent film switching component, which is used to pull the transparent film to take away the attachment layer that affects the imaging of the outer lens. The transparent film switching component is also used to fold the pulled transparent film in half to form a film package that wraps the attachment layer;

[0008] The floating module on water includes a floating block, a recovery tube is provided at the bottom of the floating block, and a receiving port connected to the recovery tube is opened on the floating block. The recovery tube extends to the membrane switching component at one end away from the floating block. The membrane switching component is also used to release the membrane package into the recovery tube. The density of the membrane package is less than the density of the water.

[0009] The above scheme has the following beneficial effects:

[0010] 1. In this solution, the underwater collection module is placed on the artificial reef for long-term ecological parameter collection. The optical collectors are all attached with a transparent film on the outer lens. When factors such as microorganisms, algae and sediments in the water affect the imaging of the outer lens, the transparent film switching component is activated, and the transparent film switching component will remove the outermost transparent film, so that the influence of factors such as attached microorganisms, algae and sediments disappears with the removal of the transparent film, so that the underwater collection module can be in the underwater environment for a long time without frequent manual maintenance.

[0011] 2. In this solution, after the permeable membrane is removed, it will be folded in half so that the attachment layer formed by microorganisms, algae and sediments is contained in the interlayer after the permeable membrane is folded, forming a membrane package. The membrane package can protect the attachment layer in the membrane package from being further affected by the water body. The membrane package will then be released into the recovery tube, which is filled with water. The density of the membrane package is less than the density of the water, so that it floats to the surface of the water in the recovery tube and is constrained by the recovery tube. Users can regularly go to the floating block, obtain the membrane package and take it back to the laboratory for testing, thereby obtaining ecological information of artificial reefs.

[0012] Furthermore, the underwater acquisition module includes a power supply, a flow rate detector and a controller, and the optical collector is one or more of a water quality spectrometer and a camera.

[0013] Beneficial effects: In addition to conventional cameras used to obtain underwater images, optical collectors can also be used in optical instruments such as water quality spectrometers. Due to the existence of undercurrents, the flow velocity detector can detect the flow velocity at the artificial reef, which is more accurate than collecting surface data.

[0014] Furthermore, the membrane switching assembly includes a casing, a plurality of pulling rods are provided on the casing, one ends of the pulling rods are respectively fixedly connected to the transparent membrane, a through slot is opened in the casing, the through slot is connected to the recovery pipe, an electric pressing plate is provided in the through slot, a first driving member for driving the pulling rod to pull the transparent membrane to the through slot is provided on the casing, and the electric pressing plate is used to press the transparent membrane in the through slot to form a membrane package and destroy the connection between the transparent membrane and the pulling rod.

[0015] Beneficial effect: The pulling rod is fixed to each layer of the transparent film, so that the first driving member drives the pulling rod to move and directly pulls down the transparent film. The pulled transparent film will move into the through slot, and the electric clamping plate will clamp and press the transparent film, so that the transparent film will be folded in half and form a film package. At the same time, under the clamping and pressing action, the transparent film will be torn off the pulling rod to complete the release of the film package.

[0016] Furthermore, the transparent films are all provided with sorting numbers and matching strips, which are used to match the transparent films to form film packages when the electric clamping plate presses the transparent films, and the controller records the time node of pulling the transparent films.

[0017] Beneficial effects: If the user does not collect the membrane package for a long time, the membrane package will accumulate in the recovery tube. Since the attachment layer in the membrane package will deteriorate, the membrane package cannot be identified, which will lead to the selection of the deteriorated attachment layer for analysis, affecting the judgment of the artificial reef ecology. The sorting number can be used as an identification to distinguish each membrane package. At the same time, according to the time node of pulling the permeable membrane and the order of the sorting number recorded by the controller, the production time of each membrane package can be determined, and the deteriorated membrane package can be eliminated. The matching strip can have better sealing after the permeable membrane forms a membrane package, reducing the probability of deterioration of the attachment layer in the membrane package.

[0018] Furthermore, the underwater collection module includes a mounting plate, which is detachably connected to the artificial fish reef, a slide rail is provided on the mounting plate, a base is slidably connected to the slide rail, and a second driving member for driving the base to slide is provided on the slide rail.

[0019] Beneficial effect: The second driving member can drive the base to change position, thereby providing stronger functionality and being able to fine-tune the monitoring position underwater.

[0020] Furthermore, the power supply and the controller are both located in the base, the flow rate detector and the optical collector are both located on the base, the flow rate detector and the optical collector are both waterproofed, and a pseudo decorative piece is provided on the side of the base away from the mounting plate.

[0021] Beneficial effects: The electrical components are all installed on the base and move with the base. At the same time, the pseudo-decoration can hide the base in the environment and reduce the disturbance to the artificial reef organisms.

[0022] Furthermore, a solar panel is provided on the top of the floating block, and the floating module on the water is electrically connected to the underwater collection module through a power line, and the power line is fixedly connected to the recovery pipe.

[0023] Beneficial effects: Solar panels can convert sunlight into electrical energy for power supply, which can facilitate the long-term deployment of underwater collection modules.

[0024] Furthermore, it also includes a recognition system, which is used to obtain images collected by the optical collector, and the recognition system is used to identify organisms in the image and periodically count each organism.

[0025] Beneficial effects: Biological species, quantity and diversity are part of ecological surveys. Biological identification can be performed through image acquisition screens to count biological species, quantity and diversity.

[0026] Furthermore, the recognition system is used to identify obstacles. When the recognition system identifies a moving obstacle, the controller controls the second driving member to make the base slide to avoid the obstacle. When the recognition system identifies an obstacle attached to the base, the controller controls the second driving member to make the base slide to throw the obstacle off.

[0027] Beneficial effects: Various garbage and debris may be mixed in the water, which may easily collide with the underwater acquisition module and cause damage, or attach to the underwater acquisition module, affecting data collection. The recognition system is extended on biometrics, and can identify obstacles in the water, and control the second drive member to avoid or drop according to the impact of the obstacles.

[0028] A data collection method for artificial reef ecological assessment, comprising:

[0029] Step 1: carry the underwater collection module and the floating module to the waters near the artificial fish reef, dive and install the underwater collection module on the artificial fish reef, the floating module floats on the water surface, and the floating module is connected to the power cord through the recovery pipe, so that the underwater collection module serves as the anchor point of the floating module;

[0030] Step 2, obtaining the ecological parameters collected by the underwater collection module, by one or more of recovering the underwater collection module, connecting the signal line of the floating module on the water to the underwater collection module, and connecting the remote signal to the underwater collection module;

[0031] Step three: Periodically go to the floating module on the water, take out the floating membrane package from the recovery tube and bring it back to the laboratory, disassemble the membrane package and obtain the attachment layer.

[0032] Beneficial effects: Data collection through the underwater acquisition module can be carried out for a long time to collect data underwater, reducing manpower consumption. At the same time, the transparent membrane switching component of the underwater acquisition module can not only regularly maintain the outer lens to ensure the use of the optical collector, but also collect biological samples and transport them to the water surface, greatly facilitating the data collection process.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is further described in detail through specific implementation methods:

[0042] As attached Figure 1-Figure 3 Shown: Data collection system for artificial reef ecological assessment, including:

The optical collectors 1 are used for spectral detection and image acquisition respectively. The optical collectors 1 include outer lenses 2. The outer lenses 2 are used to provide a channel for light to enter and exit the optical collector 1. The outer lenses 2 are covered with several layers of transparent films 3.

[0044] The underwater collection module is used to be placed on an artificial reef for long-term ecological parameter collection. The optical collector 1 is attached with a transparent film 3 on the outer lens 2. When factors such as microorganisms, algae and sediments in the water affect the imaging performance of the outer lens 2, the transparent film 3 switching component is activated, and the transparent film 3 switching component will remove the outermost transparent film 3, so that the influence of factors such as attached microorganisms, algae and sediments disappears with the removal of the transparent film 3, so that the underwater collection module can be in the underwater environment for a long time without frequent manual maintenance.

[0045] The floating module on water includes a floating block 4, a recovery tube 5 is provided at the bottom of the floating block 4, a taking port 15 connected to the recovery tube 5 is opened on the floating block 4, and the recovery tube 5 extends from one end of the floating block 4 to the membrane switching component 3, and the membrane switching component 3 is also used to release the membrane package into the recovery tube 5, and the density of the membrane package is less than the density of the water body.

[0046] After the permeable membrane 3 is removed, it will be folded in half so that the attachment layer formed by microorganisms, algae and sediments is contained in the interlayer after the permeable membrane 3 is folded, forming a membrane package, which can protect the attachment layer in the membrane package from being further affected by the water body. The membrane package will then be released into the recovery tube 5, which is filled with water, and the density of the membrane package is less than the density of the water body, so that it floats to the surface of the water in the recovery tube 5 and is constrained by the recovery tube 5 to the recovery tube 5. The user can regularly go to the floating block 4, put his hand into the access port 15, obtain the membrane package and take it back to the laboratory for testing, so as to obtain the ecological information of the artificial reef.

In addition to conventional cameras used to obtain underwater images, the optical collector 1 can also be used in optical instruments such as water quality spectrometers. Due to the existence of undercurrents, the flow rate detector 6 can detect the flow rate at the artificial reef, which is more accurate than collecting surface data.

[0049] The pulling rod 8 is fixed to each layer of the transparent film 3, so that the first driving member 11 drives the pulling rod 8 to move and directly pulls down the transparent film 3. The pulled transparent film 3 will move into the through slot 9, and the electric clamping plate 10 will clamp and press, so that the transparent film 3 is folded in half and forms a film package. At the same time, under the clamping and pressing action, the transparent film 3 will be torn off the pulling rod 8, and the film package is released.

[0050] The transparent membrane 3 is provided with a sorting number and a matching strip, which is used to match the transparent membrane 3 to form a membrane package when the electric clamping plate 10 presses the transparent membrane 3, and the controller records the time node of pulling the transparent membrane 3.

[0051] If the user does not collect the membrane package for a long time, the membrane package will accumulate in the recovery tube 5. Since the attachment layer in the membrane package will deteriorate, the membrane package cannot be identified, which will result in the selection of the deteriorated attachment layer for analysis, affecting the judgment of the artificial reef ecology.

[0055] The electrical components are all mounted on the base 14 and move with the base 14. At the same time, the pseudo decorative parts can hide the base 14 in the environment, reducing the disturbance to the artificial reef organisms.
