Description

Technical Field

[0001] The present invention relates to the technical field of wetland bird observation, and specifically to an intelligent observation system and method for wetland bird diversity based on voice recognition technology. Background Art

[0002] Wetland ecosystems are key areas for global biodiversity conservation and play an important role especially in bird habitat and migration. With the increasing demand for ecological environment protection, the observation of wetland birds has become a core task in scientific research and management.

[0003] In the patent with the publication number CN209693756U, a bird attracting and perching device for the study of wild bird ecological habits is proposed. This device lures birds to stay on the main perching pole by delivering bird food to collect bird voices or images for observation purposes. However, this method has the following defects: This device usually uses an insertion rod on the base to insert into the soil for support. If it is applied to wetland areas, due to the soft wetland soil and low soil bearing capacity, when the number of birds staying on the main perching pole is too large or the individual weight is relatively large (for example, the weight of wading birds such as grey herons can reach 2 - 3 kg), the device will sink, affecting the long-term stability of the entire observation system. For this reason, we propose an intelligent observation system and method for wetland bird diversity based on voice recognition technology. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent observation system and method for wetland bird diversity based on voice recognition technology to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: An intelligent observation system for wetland bird diversity based on voice recognition technology, which is wirelessly connected to an external monitoring terminal. The observation system includes a bird feeder, and a perching board corresponding to its discharge end is provided at the bottom of the bird feeder. A voiceprint acquisition and recognition module for collecting bird voiceprint data and performing species recognition based on the bird voiceprint data is provided on the bird feeder, and an anti-sinking support mechanism connected to the bird feeder is also included; wherein, the anti-sinking support mechanism includes: A movable frame, one end of which is connected to the bird feeder, and the other end is movably inserted with a support frame. The support frame and the movable frame are connected by a spring member, and the bottom of the support frame is connected with a bottom plate; A sliding seat, which is movably sleeved on the outer wall of the support frame and is located below the movable frame. Connecting arms are hinged on both sides of the sliding seat, and the other ends of the connecting arms are hinged with a movable plate. The movable plate is slidably arranged in a notch opened on the bottom plate, and the movable plate is connected with one inner wall of the notch by an elastic connecting member.

[0006] A further improvement is that a detection sensor 1 for contacting with the movable frame and electrically connected with the controller is embedded on the top of the sliding seat, and a driving mechanism connected with the perch plate is provided at the bottom of the bird feeder; When the detection sensor contacts the movable frame, the driving mechanism controls the perch plate to move toward one side of the bird feeder through the controller. The perch plate is slidably connected to the bottom of the bird feeder, and a reset elastic structure is provided between the perch plate and the bird feeder.

[0007] A further improvement is that a limit block is provided at the bottom of the bird feeder, which is used to contact one end of the perch board when the perch board moves to a preset position, and a detection sensor 2 and an electromagnetic block electrically connected to the controller are embedded in the limit block, and a magnetic block is embedded at one end of the perch board; When the detection sensor 2 detects that the perch board is in contact with the limit block, the controller controls the electromagnetic block to be energized to adsorb the magnetic block, and controls the driving mechanism to stop working. The controller includes a timing module, which is used to control the electromagnetic block to be powered off after a preset time is reached, and the driving mechanism resets to reset the perch board.

[0008] A further improvement is that a feeding trough is provided on the top of the perch plate, and a material guide partition plate is provided in the feeding trough. The material guide partition plate is V-shaped, one end of which is in contact with the bottom of the feeding trough, and the other end is connected to the bird feeder and is located below the discharge end of the bird feeder. The width of the material guide partition plate is adapted to the width of the feeding trough.

[0009] A further improvement is that a baffle is provided on the top of the voiceprint collection and recognition module, photovoltaic panels are symmetrically embedded on the baffle, the photovoltaic panels are connected to a power supply for power supply, a transmission shaft is rotatably provided on the baffle plate between the two photovoltaic panels, and the outer wall of the transmission shaft is provided with several groups of connecting pieces for fitting with the top surface of the baffle, and one end of the transmission shaft is connected to the driving mechanism through a transmission member.

[0010] A further improvement is that the driving mechanism includes a rotating shaft rotatably arranged at the bottom of the bird feeder, a rotating device arranged at one end of the rotating shaft, and a pull rope wound around the outer wall of the rotating shaft and connected to the perch plate at one end.

[0011] A further improvement is that the transmission member includes a transmission rod rotatably arranged on the side wall of the bird feeder, one end of the transmission rod is transmission-connected to the rotating shaft through a worm gear transmission group, and the other end of the transmission rod is transmission-connected to the transmission shaft through a sprocket transmission group.

[0012] A further improvement is that the bird feeder is also provided with an image acquisition device for acquiring image data of birds on the perching board.

[0013] A further improvement is that the observation system further includes two sets of connecting mechanisms symmetrically arranged on the side wall of the sliding seat; wherein, each connecting mechanism includes a guide rail connected to the sliding seat, a connecting slider is slidably arranged in the guide rail, the connecting slider is connected to the inner wall of the sliding seat through an elastic member, and one end of the connecting slider is connected with a tree fixing device for fixing on the outer wall of the tree.

[0014] A wetland bird diversity intelligent observation method based on voice recognition technology, using the above observation system, includes the following steps: S1: Deploy the observation system in the wetland target area, and put bird food on the perching board through the bird feeder to attract birds to perch; S2: Collect bird voiceprint data in real time through the voiceprint acquisition and recognition module and conduct species recognition, and transmit the recognition result to the monitoring terminal; wherein, when the weight of the bird on the perching board causes the movable frame to move downward relative to the support frame, the spring member will be compressed. When the movable frame continues to move downward to a preset position, the movement of the movable frame will drive the sliding seat to move downward, and then the sliding seat drives the movable plate to unfold outward through the connecting arm.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The present invention is provided with an anti-sinking support mechanism. By moving the movable frame relative to the support frame to compress the spring member, it effectively avoids the direct impact of the gravity of the bird on the soft ground of the wetland, causing the entire observation system to sink. When the number of birds increases or the weight continues to act, causing the movable frame to continue to move downward, the movement of the movable frame drives the sliding seat to move downward, and then drives the movable plate to unfold outward through the connecting arm, increasing the contact area between the bottom plate and the ground, further reducing the influence of the bird gravity on the observation system. At the same time, when the movable frame contacts the sliding seat, the driving mechanism also makes the perching board move, reducing the space available for birds to perch on the perching board, thereby reducing the number of birds on the perching board, and further preventing the observation system from sinking due to too many birds or a relatively large weight of individual birds.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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.

[0019] Embodiment 1 Please refer to the attached Figure 1 - attached Figure 3 , a wetland bird diversity intelligent observation system based on voice recognition technology, which is wirelessly connected to an external monitoring terminal to achieve remote communication; The observation system includes a bird feeder 1, which is a conventional device in the art and will not be described in detail here; a perching board 2 corresponding to the discharge end is provided at the bottom of the bird feeder 1. The perching board 2 is for birds to perch and is used to carry the bird food put by the bird feeder 1 to attract birds. Specifically, when in use, the external monitoring terminal can control the bird feeder 1 to work at a certain period or manually to put a certain amount of bird food on the perching board 2; A voiceprint acquisition and recognition module 3 for collecting bird voiceprint data and identifying the species based on the bird voiceprint data is provided on the bird feeder 1. The voiceprint acquisition and recognition module 3 is a conventional device in the art. For example, the voiceprint acquisition and recognition module 3 includes a voice acquisition module (such as a microphone or a microphone, etc.) for collecting bird voiceprint data and preprocessing (denoising) the bird voiceprint data, a voiceprint recognition module for receiving the bird voiceprint data, matching it with the database samples, and identifying the bird species. Of course, the above voiceprint acquisition and recognition module 3 is not limited to the above structural components; It also includes an anti-sinking support mechanism connected to the bird feeder 1; among them, the anti-sinking support mechanism includes: The movable frame 4 has one end connected to the bird feeder 1 and the other end movably inserted with a support frame 5. The support frame 5 and the movable frame 4 are connected by a spring member 7 (such as a spring). The bottom of the support frame 5 is connected to a bottom plate 6, and the bottom of the bottom plate 6 has an insertion rod for inserting into the wetland soil to fix the observation system in the wetland target area for observation tasks; As birds perch on the perching board 2, due to the relatively soft soil in the wetland area, and if the number of perching birds is too large or the weight of some birds is heavy, under the gravitational force of the birds, the bird feeder 1 and the movable frame 4 will move downward relative to the support frame 5 and compress the spring member 7, effectively preventing the gravitational force of the birds from directly impacting the soft wetland ground and causing the entire observation system to sink; The sliding seat 8 is movably sleeved on the outer wall of the support frame 5 and is located below the movable frame 4. Both sides of the sliding seat 8 are hinged with connecting arms 9. The other ends of the connecting arms 9 are hinged with a movable plate 11. The movable plate 11 is slidably arranged in a notch opened on the bottom plate 6, and the movable plate 11 is connected to one inner wall of the notch by an elastic connecting member (such as a spring); When the movable frame 4 continues to move downward to a preset position, it drives the sliding seat 8 to move downward, and then drives the movable plate 11 to expand outward through the connecting arms 9, increasing the contact area between the bottom plate 6 and the ground through the movable plate 11, and further reducing the influence of the gravitational force of the birds on the observation system.

[0020] Preferably, an image acquisition device 21 for acquiring image data of birds on the perching board 2 is further provided on the bird feeder 1 in this embodiment. The image acquisition device 21 is, for example, a camera, so as to better observe wetland birds; A method for intelligent observation of wetland bird diversity based on voice recognition technology, using the above observation system, includes the following steps: S1: Deploy the observation system in the wetland target area, and put bird food into the perching board 2 through the bird feeder 1 to attract birds to perch; S2: Real-time collect bird vocalization data through the vocalization fingerprint acquisition and recognition module 3 and perform species recognition, and transmit the recognition result to the monitoring terminal; wherein, when the weight of the birds on the perching board 2 causes the movable frame 4 to move downward relative to the support frame 5, the spring member 7 will be compressed. When the movable frame 4 continues to move downward to a preset position, the movement of the movable frame 4 will drive the sliding seat 8 to move downward, and then the sliding seat 8 drives the movable plate 11 to expand outward through the connecting arms 9.

[0021] Embodiment 2 Please refer to the appendix Figure 1 - Appendix Figure 6, on the basis of Embodiment 1, a first detection sensor 12 for contacting the movable frame 4 and electrically connected to the controller is embedded in the top of the sliding seat 8 in this embodiment. The first detection sensor 12 is, for example, a contact sensor, etc., and its model is selected according to the actual situation, and will not be elaborated here. A driving mechanism connected to the perching board 2 is provided at the bottom of the bird feeder 1; When the first detection sensor 12 contacts the movable frame 4, the driving mechanism controls the perching board 2 to move towards the side of the bird feeder 1 by the controller. The perching board 2 is slidably connected to the bottom of the bird feeder 1. For example, they can be slidably connected by a slider and a slide rail, and a reset elastic structure (such as a spring) is provided between the perching board 2 and the bird feeder 1; Through the above setting method, when the movable frame 4 continues to move down to contact the sliding seat 8, it will contact the first detection sensor 12, and then the driving mechanism makes the perching board 2 move, reducing the space available for birds to perch on the perching board 2, thereby reducing the number of birds on the perching board 2, thus preventing the further subsidence of the observation system. It will neither completely prevent birds from perching and affect the observation, nor can it actively guide some birds to leave through space compression, reducing the interference of human intervention on natural behavior.

[0022] Preferably, a limiting block 15 is provided at the bottom of the bird feeder 1 in this embodiment, which is used to contact one end of the perching board 2 when the perching board 2 moves to a preset position. A second detection sensor 16 and an electromagnet block electrically connected to the controller are embedded in the limiting block 15. The second detection sensor 16 is, for example, a pressure sensor, and a magnetic block is embedded at one end of the perching board 2; When the second detection sensor 16 detects that the perching board 2 contacts the limiting block 15, the controller controls the electromagnet block to be energized to adsorb the magnetic block, and at the same time the driving mechanism stops working. The controller includes a timing module, which is used to control the electromagnet block to be powered off after reaching the preset time, and the driving mechanism resets to work, so that the perching board 2 resets. The timing module is, for example, timed for 5 - 30 minutes; Through the above setting, the electromagnet block and the magnetic block cooperate to adsorb the moved perching board 2, blocking the possibility of birds returning to the perching board 2 in the short term after leaving. Under the action of the timing module, the perching board 2 automatically resets within the preset time, without affecting the continuous bird observation work.

[0023] Preferably, the driving mechanism in this embodiment includes a rotating shaft 14 rotatably provided at the bottom of the bird feeder 1, a rotating device 13 (such as a servo motor and a reducer) provided at one end of the rotating shaft 14, and a pulling rope wound around the outer wall of the rotating shaft 14 and connected to the perching board 2 at one end; It should be noted that when the perching board 2 is in contact with the limit block 15, a portion of the perching board 2 is still available for birds to perch on. However, compared with the initial state, the area on the perching board 2 available for birds to perch on is smaller. This reduces the impact of the weight of the birds on the observation system without affecting the normal observation work.

[0024] Preferably, a feeding trough 10 is provided on the top of the perch plate 2 of the present embodiment, and a material guide partition plate 17 is provided in the feeding trough 10. The material guide partition plate 17 is V-shaped, one end of which contacts the bottom of the feeding trough 10, and the other end is connected to the bird feeder 1 and is located below the discharge end of the bird feeder 1. The width of the material guide partition plate 17 is adapted to the width of the feeding trough 10. The guide partition plate 17 guides the bird feed discharged from the discharge end of the bird feeder 1 on the one hand, and on the other hand, it reduces the space of the feeding trough 10 when the perch plate 2 moves, and uses the narrowed trough space to concentrate the remaining bird feed, guiding the birds to finish eating faster and leave actively, thereby indirectly reducing the risk of continuous load-bearing of the system.

[0025] Example 3 Please see attached Figure 5 -Attached Figure 6 On the basis of Example 2, a shielding plate 18 is provided on the top of the voiceprint collection and recognition module 3 of this embodiment. The shielding plate 18 is V-shaped and plays the role of sunshade and rainproof. Photovoltaic panels 20 are symmetrically embedded on the shielding plate 18. The photovoltaic panels 20 are connected to a power supply for power supply. The power supply can be provided on the bird feeder 1 (not shown in the figure). The photovoltaic panels 20 and the power supply can provide power for the electrical components in the observation system. A transmission shaft is rotatably provided on the shielding plate 18 between the two photovoltaic panels 20, and the outer wall of the transmission shaft is provided with a plurality of groups of connecting pieces 19 for fitting with the top surface of the shielding plate 18. The connecting piece 19 can be a brush plate, and one end of the transmission shaft is connected to the driving mechanism through a transmission member.

[0026] Preferably, the transmission member of this embodiment includes a transmission rod rotatably arranged on the side wall of the bird feeder 1, one end of the transmission rod is connected to the rotating shaft 14 through a worm gear transmission group 27 (including a worm mounted on the outer wall of the rotating shaft 14 and a worm wheel mounted on one end of the transmission rod and meshing with the worm), and the other end of the transmission rod is connected to the transmission shaft through a sprocket transmission group (including a sprocket and a chain).

[0027] Through the above-mentioned arrangement, when the driving mechanism is working, the transmission shaft is driven by the transmission member, and the transmission shaft drives the connecting piece 19 to rotate. Birds can be driven away through the connecting piece 19 to prevent birds perching on the baffle plate 18 from causing the observation system to sink. In addition, the arrangement of the connecting piece 19 can also scrape off residues (such as bird droppings or other dust particles, etc.) that fall on the photovoltaic panel 20 to avoid affecting the stable use of the photovoltaic panel 20.

[0028] Example 4 Please refer to the attached Figure 1 - Attachment Figure 4 , on the basis of Embodiment 1, the observation system of this embodiment further includes two sets of connection mechanisms symmetrically arranged on the side wall of the sliding seat 8; wherein, the connection mechanism includes a guide rail 23 connected to the sliding seat 8, and a connection slider 24 is slidably arranged in the guide rail 23; the connection slider 24 is connected to the inner wall of the sliding seat 8 through an elastic member 25 (such as a spring), and one end of the connection slider 24 is connected with a tree fixing device 22 for fixing on the outer wall of the tree. The tree fixing device 22 is, for example, a conventional device in the art (such as a hoop structure with an anti-slip buckle). When using this observation system, it is deployed between two trees in a wetland area and connected to the outer wall of the tree through the tree fixing device 22. When the movable frame 4 drives the sliding seat 8 to move downward under the action of the gravity of the bird, the connection rope 26 pulls the connection slider 24 to squeeze the elastic member 25, effectively dispersing the downward pressure and significantly reducing the instantaneous bearing pressure on the wetland ground. At the same time, when the connection slider 24 is pulled to the final position by the connection rope 26, its mechanical limit structure will forcibly terminate further downward movement, effectively preventing the observation system from sinking excessively.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
