Description

Technical Field

[0001] This invention relates to the field of wetland bird observation technology, specifically to a smart observation system and method for wetland bird diversity based on speech recognition technology. Background Technology

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

[0003] A bird-attracting perch device for studying the ecological habits of wild birds was proposed in publication number CN209693756U. This device attracts birds to perch on the main perch by providing bird food, and collects bird sounds or images to achieve the observation purpose. However, this method has the following drawbacks: This device typically uses a base with insert rods inserted into the soil for support. However, when applied to wetland areas, the loose soil and low bearing capacity can cause the device to sink when too many birds or large birds (such as herons weighing 2-3 kg) perch on the main rod, affecting the long-term stability of the entire observation system. Therefore, we propose a smart observation system and method for wetland bird diversity based on speech recognition technology. Summary of the Invention

[0004] The purpose of this invention is to provide a smart observation system and method for wetland bird diversity based on speech recognition technology, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart observation system for wetland bird diversity based on voice recognition technology is disclosed. The system is wirelessly connected to an external monitoring terminal. The system includes a bird feeder with a perch at its bottom corresponding to the feed outlet. The bird feeder is equipped with a voiceprint acquisition and recognition module for collecting bird voiceprint data and identifying bird species based on that data. The system also includes an anti-sinking support mechanism connected to the bird feeder. The anti-sinking support mechanism comprises: The movable frame has a bird feeder connected to one end and a support frame movably inserted to the other end. The support frame and the movable frame are connected by a spring. The bottom of the support frame is connected to a base plate. A sliding seat is movably sleeved on the outer wall of the support frame and located below the movable frame. Connecting arms are hinged to both sides of the sliding seat, and a movable plate is hinged to the other end of the connecting arm. The movable plate is slidably disposed in a recess opened in the base plate, and the movable plate is connected to the inner wall of one side of the recess through an elastic connector.

[0006] A further improvement is that a detection sensor is embedded at the top of the sliding seat for contacting the movable frame and electrically connected to the controller, and a drive mechanism connected to the perch is provided at the bottom of the bird feeder; When the detection sensor contacts the movable frame, the drive mechanism is controlled by the controller to move the perch board toward the bird feeder side. The perch board is slidably connected to the bottom of the bird feeder, and a reset elastic structure is provided between the perch board and the bird feeder.

[0007] A further improvement is that the bottom of the bird feeder is provided with a limiting block for contacting one end of the perch when the perch moves to a preset position. The limiting block is equipped with a second detection sensor and an electromagnetic block that are electrically connected to the controller. A magnetic block is embedded at one end of the perch. When the second sensor detects that the perch is in contact with the limiting block, the controller controls the electromagnetic block to be energized to attract the magnetic block, and at the same time controls the drive mechanism to stop working. The controller includes a timing module, which is used to control the electromagnetic block to be de-energized after a preset time is reached, and the drive mechanism to reset so that the perch is reset.

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

[0009] A further improvement is that the voiceprint acquisition and recognition module is provided with a shielding plate on the top, and photovoltaic panels are symmetrically embedded on the shielding plate. The photovoltaic panels are connected to a power supply for power supply. A drive shaft is rotatably provided on the shielding plate between the two photovoltaic panels, and the outer wall of the drive shaft is provided with several sets of connecting pieces for fitting with the top surface of the shielding plate. One end of the drive shaft is connected to the drive mechanism through a transmission component.

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

[0011] A further improvement is that the transmission component includes a transmission rod rotatably mounted on the side wall of the bird feeder. One end of the transmission rod is connected to the rotating shaft via a worm gear transmission assembly, and the other end of the transmission rod is connected to the transmission shaft via a sprocket transmission assembly.

[0012] A further improvement is that the bird feeder is also equipped with an image acquisition device for collecting image data of birds on the perch.

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

[0014] A smart observation method for wetland bird diversity based on speech recognition technology, utilizing the aforementioned observation system, includes the following steps: S1: Deploy the observation system in the target wetland area and use bird feeders to deliver bird food to the perches to attract birds to perch; S2: The voiceprint acquisition and recognition module collects bird voiceprint data in real time and identifies the species, and transmits the recognition results to the monitoring terminal; when the weight of the bird on the perch causes the movable frame to move down relative to the support frame, it will compress the spring. When the movable frame continues to move down to the preset position, the movement of the movable frame will drive the sliding seat to move down, and then the sliding seat will drive the movable plate to unfold outward through the connecting arm.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention incorporates an anti-sinking support mechanism. By moving the movable frame relative to the support frame and compressing the spring components, it effectively prevents the weight of birds from directly impacting the soft wetland ground and causing the entire observation system to sink. When the number of birds increases or their weight continues to cause the movable frame to move further downward, the movement of the movable frame drives the sliding seat to move downward, which in turn 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 impact of bird weight on the observation system. At the same time, when the movable frame contacts the sliding seat, the drive mechanism also causes the perch board to move, reducing the space available for birds to perch on the perch board, thereby reducing the number of birds on the perch board and further preventing the observation system from sinking due to an excessive number of birds or the large weight of individual birds.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1

[0020] Please see the appendix Figure 1 - Appendix Figure 3 A smart observation system for wetland bird diversity based on voice recognition technology. The system is wirelessly connected to an external monitoring terminal to enable remote communication. The observation system includes a bird feeder 1, which is a conventional device in the field and will not be described in detail here. The bottom of the bird feeder 1 is equipped with a perch 2 corresponding to its discharge end. The perch 2 is used for birds to perch and also to hold the bird food put in by the bird feeder 1 to attract birds. Specifically, when in use, the external monitoring terminal can put a certain amount of bird food into the perch 2 at a certain period or manually control the bird feeder 1 to work. The bird feeder 1 is equipped with a voiceprint acquisition and recognition module 3 for collecting bird voiceprint data and identifying bird species based on the bird voiceprint data. This voiceprint acquisition and recognition module 3 is a conventional device in the field. For example, the voiceprint acquisition and recognition module 3 includes a voice acquisition module (such as a microphone or microphone) for collecting bird voiceprint data and preprocessing (noise reduction) the bird voiceprint data, receiving bird voiceprint data, matching it with database samples, and identifying bird species. Of course, the above-mentioned voiceprint acquisition and recognition module 3 is not limited to these structural components. It also includes an anti-sinking support mechanism connected to the bird feeder 1; wherein the anti-sinking support mechanism includes: The movable frame 4 is connected to the bird feeder 1 at one end and the support frame 5 is movably inserted at the other end. The support frame 5 and the movable frame 4 are connected by a spring 7 (e.g., a spring). The bottom of the support frame 5 is connected to a base plate 6. The bottom of the base plate 6 has an insert rod so that it can be inserted into the wetland soil to fix the observation system in the target area of ​​the wetland for observation tasks. As birds perch on the perch board 2, due to the relatively loose soil in the wetland area, and if there are too many birds or some birds are heavy, the bird feeder 1 and the movable frame 4 will move downward relative to the support frame 5 and compress the spring 7 under the influence of the birds' gravity. This effectively prevents the birds' gravity 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 located below the movable frame 4. Both sides of the sliding seat 8 are hinged with connecting arms 9, and the other end of the connecting arm 9 is hinged with a movable plate 11. The movable plate 11 is slidably disposed in a recess opened on the bottom plate 6, and the movable plate 11 is connected to the inner wall of one side of the recess through an elastic connector (e.g., a spring). When the movable frame 4 continues to move down to the preset position, it drives the sliding seat 8 to move down, and then drives the movable plate 11 to unfold outward through the connecting arm 9. The movable plate 11 increases the contact area between the base plate 6 and the ground, further reducing the impact of the bird's gravity on the observation system.

[0021] Preferably, the bird feeder 1 in this embodiment is also provided with an image acquisition device 21 for collecting image data of birds on the perch 2. The image acquisition device 21 is, for example, a camera, so as to better observe wetland birds. A smart observation method for wetland bird diversity based on speech recognition technology, utilizing the aforementioned observation system, includes the following steps: S1: Deploy the observation system in the target wetland area and use bird feeder 1 to feed birds onto perch board 2 to attract birds to perch; S2: The voiceprint acquisition and recognition module 3 collects bird voiceprint data in real time and performs species identification, and transmits the identification results to the monitoring terminal; when the weight of the bird on the perch 2 causes the movable frame 4 to move down relative to the support frame 5, it will compress the spring 7. When the movable frame 4 continues to move down to the preset position, the movement of the movable frame 4 will drive the sliding seat 8 to move down, and then the sliding seat 8 will drive the movable plate 11 to unfold outward through the connecting arm 9.

[0022] Example 2

[0023] Please see the appendix Figure 1 - Appendix Figure 6Based on Embodiment 1, the top of the sliding seat 8 in this embodiment is provided with a detection sensor 12 for contacting the movable frame 4 and electrically connected to the controller. The detection sensor 12 is, for example, a contact sensor, and its model is selected according to the actual situation. It will not be described in detail here. The bottom of the bird feeder 1 is provided with a drive mechanism connected to the perch 2. When the detection sensor 12 contacts the movable frame 4, the drive mechanism is controlled by the controller to move the perch 2 toward the bird feeder 1. The perch 2 and the bottom of the bird feeder 1 are slidably connected. For example, the two can be slidably connected by a slider and a slide rail. A reset elastic structure (e.g., a spring) is provided between the perch 2 and the bird feeder 1. With this setup, when the movable frame 4 continues to move down and contacts the sliding seat 8, it will contact the detection sensor 12, thereby driving the mechanism to move the perch 2, reducing the space available for birds to perch on the perch 2, thus reducing the number of birds on the perch 2. This prevents the observation system from sinking further, ensuring that the birds are not completely unable to perch and thus affecting the observation, while also guiding some birds to leave voluntarily through space compression, reducing human intervention interference with natural behavior.

[0024] As a preferred embodiment, the bird feeder 1 in this embodiment is provided with a limiting block 15 at the bottom, which is used to contact one end of the perch 2 when the perch 2 moves to a preset position. The limiting block 15 is provided with a second detection sensor 16 and an electromagnetic block that are electrically connected to the controller. The second detection sensor 16 is, for example, a pressure sensor, and a magnetic block is provided at one end of the perch 2. When the second sensor 16 detects that the perching board 2 is in contact with the limiting block 15, the controller controls the electromagnetic block to be energized to attract the magnetic block, and at the same time the drive mechanism stops working. The controller includes a timing module, which is used to control the electromagnetic block to be de-energized after a preset time is reached, and the drive mechanism to be reset so that the perching board 2 is reset. The timing module is, for example, a timing of 5-30 minutes. With this setup, the electromagnetic block and the magnetic block work together to attract the perch 2 after it has moved, preventing the birds from returning to the perch 2 in the short term after they leave. Under the action of the timing module, the perch 2 automatically resets within a preset time, without affecting the continued bird observation work.

[0025] As a preferred embodiment, the driving mechanism includes a rotating shaft 14 located at the bottom of the bird feeder 1, a rotating device 13 (e.g., a servo motor and a reducer) located at one end of the rotating shaft 14, and a pull rope wound around the outer wall of the rotating shaft 14 and connected to the perch 2 at one end. It should be noted that when the perch 2 is in contact with the limiting block 15, there is still a part of the perch 2 available for birds to perch. However, compared with the initial state, the area available for birds to perch on the perch 2 is smaller. This reduces the impact of the birds' weight on the observation system without affecting normal observation work.

[0026] Preferably, in this embodiment, the perch board 2 has a feeding trough 10 on the top, and a feed guide partition 17 is provided in the feeding trough 10. The feed guide partition 17 is V-shaped, with one end in contact with the bottom of the feeding trough 10 and the other end connected to the bird feeder 1 and located below the feed outlet of the bird feeder 1. The width of the feed guide partition 17 is adapted to the width of the feeding trough 10. The guide plate 17 guides the bird food from the bird feeder 1 and reduces the space of the feeding trough 10 when the perch 2 moves. The narrowed trough space concentrates the remaining bird food, guiding the birds to finish eating and leave on their own, thereby indirectly reducing the risk of continuous load on the system.

[0027] Example 3

[0028] Please see the appendix Figure 5 - Appendix Figure 6 Based on Embodiment 2, the voiceprint acquisition and recognition module 3 of this embodiment is provided with a shield 18 on the top. The shield 18 is V-shaped and serves to provide shade and rain protection. Photovoltaic panels 20 are symmetrically embedded on the shield 18. The photovoltaic panels 20 are connected to a power supply for power supply. The power supply can be located on the bird feeder 1 (not shown in the figure). The photovoltaic panels 20 and the power supply can provide power to the electrical components in this observation system. A drive shaft is rotatably provided on the shield 18 between the two photovoltaic panels 20. The outer wall of the drive shaft is provided with several sets of connecting pieces 19 for contacting the top surface of the shield 18. The connecting pieces 19 can be brush plates. One end of the drive shaft is connected to the drive mechanism through a transmission component.

[0029] Preferably, the transmission component in this embodiment includes a transmission rod rotatably mounted on the side wall of the bird feeder 1. One end of the transmission rod is connected to the rotating shaft 14 via a worm gear transmission assembly 27 (including a worm sleeved on the outer wall of the rotating shaft 14 and a worm wheel sleeved on one end of the transmission rod and meshing with the worm). The other end of the transmission rod is connected to the transmission shaft via a sprocket transmission assembly (including a sprocket and a chain).

[0030] With the above-mentioned configuration, when the drive mechanism is working, it also drives the transmission shaft through the transmission component. The transmission shaft drives the connecting piece 19 to rotate. The connecting piece 19 can drive away birds to prevent birds perched on the shield 18 from causing the observation system to sink. In addition, the setting of the connecting piece 19 can also scrape off the residue (such as bird droppings or other dust particles) that fall on the photovoltaic panel 20, so as to avoid affecting the stable use of the photovoltaic panel 20.

[0031] Example 4

[0032] Please see the appendix Figure 1 - Appendix Figure 4 Based on Embodiment 1, the observation system in this embodiment further includes two sets of connecting mechanisms symmetrically arranged on the side wall of the sliding seat 8. The connecting mechanism includes a guide rail 23 connected to the sliding seat 8, and a connecting slider 24 is slidably arranged inside the guide rail 23. The connecting slider 24 is connected to the inner wall of the guide rail 23 by an elastic element 25 (e.g., a spring). One end of the connecting slider 24 is connected to a tree fixing device 22 for fixing to the outer wall of a tree by a connecting rope 26. The tree fixing device 22 is, for example, a conventional device in the art (e.g., a clamp structure with anti-slip buckles). When in use, the observation system is deployed between two trees in the wetland area and connected to the outer wall of the tree by the tree fixing device 22. When the movable frame 4 moves the sliding seat 8 downward under the action of the bird's gravity, the connecting rope 26 pulls the connecting slider 24 to squeeze the elastic element 25 to effectively disperse the downward pressure, which significantly reduces the instantaneous load-bearing pressure on the wetland ground. At the same time, when the connecting slider 24 is pulled to the final position by the connecting rope 26, its mechanical limiting structure will forcibly stop further downward movement, effectively preventing the observation system from sinking excessively.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
