Description

Technical Field

[0001] This application relates to the technical field of attracting survey equipment, and more specifically, to a portable device for surveying and monitoring swiftlet populations. Background Technology

[0002] The swiftlet is a small bird belonging to the family Apodidae in the order Apodiformes. It has well-developed salivary glands in its throat, which secrete saliva that solidifies in the air, forming the primary material for its nests. These nests are known as bird's nests and have high nutritional and economic value. The Javan swiftlet, which produces bird's nests, was officially listed as a Class II National Key Protected Wild Animal in my country in 2021.

[0003] Currently, swiftlets have not been domesticated and are all wild animals. Research on them usually requires playing the calls of swiftlets to attract them to the vicinity of the sound source, so that subsequent research can be carried out.

[0004] Existing attraction equipment directly plays the calls of swiftlets through speakers and then captures images through mobile phones or cameras. In order to record the feedback sound, separate microphones are often required, which means that the attraction work requires multiple people. This not only increases the traces of human intervention in the attraction process and affects the attraction effect, but also makes the transportation and use of multiple sets of equipment complicated, which is not conducive to the attraction work and affects subsequent research.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0015] According to some embodiments of this application, a receiving space is provided at the end of the top segment away from the hollow segment, and the audio acquisition structure is retractably disposed within the receiving space.

[0016] According to some embodiments of this application, the accommodating space includes a first accommodating space and a second accommodating space, the first accommodating space being located on the axial end face of the top segment away from the hollow segment, and the second accommodating space being arranged in an array and surrounding the radial outer side of the top segment.

[0017] This application provides a portable device for surveying and monitoring swiftlet populations, which mainly includes a support component, a sound-generating component, and a data acquisition component.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0034] like Figures 1 to 4 As shown in some exemplary embodiments of this application, a portable device for surveying and monitoring swiftlet populations is provided, which mainly includes: a support component 10, a sound-generating component 20, and a data acquisition component 30. The support component 10 includes a first support 11, a second support 12, and a base 13. The first support 11 is fixedly connected to the base 13, and the second support 12 is movably connected to the base 13. The sound-generating component 20 includes a sound generator 21, which is movably connected to the first support 11. The data acquisition component 30 includes an image acquisition structure 31 and an audio acquisition structure 32. The audio acquisition structure 32 is fixedly connected to the end of the second support 12 away from the base 13, and the image acquisition structure 31 is movably connected to the radially outer side of the second support 12.

[0035] In this embodiment, the sound generator 21 is specifically designed to play the calls of swiftlets for effective attraction. The sound generator 21 is movably positioned relative to the first support 11, meaning its position and direction can be freely adjusted within a certain range. The advantage of this design is that it not only allows users to adjust the orientation of the sound generator 21 according to the environment and attraction needs to optimize the sound propagation range, thereby improving the propagation efficiency of the swiftlet's call and achieving more precise attraction; it also adapts to the characteristics of the swiftlet's call propagating in different directions, enabling attraction of swiftlets from multiple directions. In this way, the sound generator 21 can more effectively cover a wider area and can flexibly adjust its sound-emitting strategy according to different attraction scenarios and the activity habits of swiftlets, thus significantly improving the effectiveness of attracting swiftlets.

[0036] In this embodiment, the audio acquisition structure 32 is designed to be fixedly connected to the end of the second support 12 away from the base 13, while the second support 12 itself is movably connected to the base 13. This ingenious arrangement allows the audio acquisition structure 32 to be displaced relative to the transmitter 21, meaning its distance from the transmitter 21 can be adjusted as needed. Specifically, when it is necessary to record the swiftlet's response to a played call, the audio acquisition structure 32 can be moved to a position away from the transmitter 21. The advantage of this design is that it effectively reduces the interference of the swiftlet's call played by the transmitter 21 on the recording effect, thereby ensuring that the recorded audio is mainly the swiftlet's natural response call, rather than the played sound. In this way, the swiftlet's call can be captured and analyzed more accurately, thereby evaluating the attraction effect and optimizing the attraction strategy. This structure not only improves the accuracy of audio acquisition but also enhances the flexibility and adaptability of the entire system, enabling it to better adapt to different environments and attraction needs.

[0037] In this embodiment, the image acquisition structure 31 is integrated into the device to achieve a camera function. This not only facilitates video recording but also facilitates subsequent data analysis and processing. Specifically, the image acquisition structure 31 can capture video of the swiftlet's activities. This video data is crucial for analyzing the swiftlet's behavioral patterns, flight paths, and interactions with other birds. Furthermore, the design of the image acquisition structure 31 allows for high-precision video recording, enabling observers to closely observe the swiftlet's flight patterns and movements. This facilitates the differentiation between barn swallows and swiftlets, especially when their appearance is similar, allowing identification through subtle differences in flight behavior.

[0038] By integrating the functions of playing calls, capturing images, and capturing audio into a single device, this embodiment provides an integrated solution that allows users to complete the entire process of attracting and collecting data using only one device. This integrated design significantly reduces operational complexity and the need for additional equipment and personnel, thereby improving the efficiency of attracting and surveying. Furthermore, the integrated device helps reduce on-site operational errors, ensures data consistency and accuracy, and provides an efficient and convenient tool for the research and conservation of swiftlets.

[0039] In some exemplary embodiments of this application, the sound generator 21 is designed in the form of a horn or loudspeaker to play sound. The sound generator 21 is capable of playing the calls of swiftlets to attract their attention and encourage them to approach.

[0040] The portable device is equipped with a control component that can adjust the real-time power of the sound generator 21. Specifically, in the initial stage of attracting swiftlets, the control component can be set to a higher output power. This is to increase the propagation range of the swiftlet's call, thereby expanding the sound coverage area and attracting swiftlets from a greater distance. As the attraction process progresses into the middle and later stages, the control component can gradually reduce the output power of the sound generator 21. This is to reduce the potential negative impact of excessive volume on the swiftlets, especially when they are already close to the device. Lowering the volume can avoid excessive stimulation or interference to the swiftlets, thus maintaining their natural behavioral patterns and increasing the success rate of attraction.

[0041] By flexibly adjusting the power of the sound generator 21, this embodiment not only improves attraction efficiency but also considers the welfare of the swiftlets, ensuring a gentle attraction process and the comfort of the swiftlets. This intelligent control method allows the equipment to adapt to different attraction stages and environmental conditions, providing users with an efficient, flexible, and animal-friendly attraction solution.

[0042] Please refer to some exemplary embodiments of this application. Figure 6 The sound generator 21 is designed in the form of a flat-mouthed horn. This design allows sound waves to propagate in a concentrated direction, thereby enhancing the sound's range in that direction. This concentrated propagation method allows the swiftlet's call to be transmitted more effectively over greater distances, which is of great significance for investigating swiftlet populations in specific directions.

[0043] The flat-mouthed horn design gives sound waves good directionality in the horizontal direction, which helps to create a concentrated sound area within a specific region. This design not only improves the efficiency of sound propagation but also helps to reduce sound diffusion in non-target areas, thus avoiding interference with swiftlets in those areas.

[0044] In practical applications, the sound generator 21 of this flat-mouthed horn can be directionally placed to propagate sound towards a specific survey area. By adjusting the orientation of the horn, the direction of sound propagation can be precisely controlled, thereby enabling the survey and research of swiftlet populations in a specific area. This design not only improves the accuracy of the survey but also helps protect the natural habitat of swiftlets by reducing sound wave interference with the surrounding environment.

[0045] In some exemplary embodiments of this application, the calls of the swiftlets are one or more of the following: calls made in advance during swiftlet group activities, calls during courtship, calls during nest building, calls during hunting, and calls during feeding.

[0046] By playing one or more combinations of these calls, the sound generator 21 can simulate the natural behavior of swiftlets at different stages of their life cycle, thereby attracting swiftlets more effectively. This diversified sound strategy can cover the different behavioral needs of swiftlets, improving the success rate and efficiency of attraction.

[0047] In practice, one or more calls can be played depending on the specific attraction objective and environmental conditions. For example, during the breeding season, calls used for courtship and nest building can be emphasized; while during the feeding season, calls used for feeding chicks can be played. This flexible sound strategy allows the embodiments of this application to adapt to different attraction needs, providing an effective tool for the research and conservation of swiftlets.

[0048] Please refer to some exemplary embodiments of this application. Figure 1 and Figure 2 The support assembly 10 consists of two main parts: a first support 11 and a second support 12. These two supports are designed to be approximately equal in height in the vertical direction to ensure the stability and balance of the entire support assembly 10. The base 13 is designed in a generally disc-shaped manner, which facilitates even weight distribution and provides a large contact area to ensure stable placement of the support assembly 10 under various ground conditions.

[0049] The first bracket 11 and the second bracket 12 are fixed to the base 13 with fasteners. This fixing method not only provides structural stability but also facilitates installation and disassembly to adapt to different usage scenarios and environments. The use of fasteners also allows for fine-tuning of the angle and position of the brackets to meet different installation requirements.

[0050] The support component 10 is designed with a platform roughly parallel to the horizontal plane, a design that takes into account the installation requirements of the acquisition component 30. The platform provides a stable and level surface, allowing the acquisition component 30 to be easily installed on it. This configuration not only ensures the stability of the acquisition component 30 but also facilitates its adjustment and maintenance.

[0051] Furthermore, in some exemplary embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 4 To reduce the impact of the speaker 21 on the audio acquisition structure 32 and the image acquisition structure 31, a special isolation frame 14 was designed. The isolation frame 14 is located on the side of the first support 11 and the second support 12 away from the base 13, and its main function is to physically separate the speaker 21 from the audio acquisition structure 32 and the image acquisition structure 31.

[0052] The design of the isolation frame 14 takes into account the physical characteristics of sound propagation, especially in the vertical direction. By placing the isolation frame 14 between the sound generator 21 and the acquisition structure, the direct transmission of sound from the sound generator 21 to the audio acquisition structure 32 can be effectively prevented, thereby reducing the interference of the sound played by the sound generator 21 on the audio acquisition. This design is particularly advantageous for accurately capturing the natural calls of swiftlets when attracting them, rather than simply recording the sound played by the sound generator 21.

[0053] Furthermore, the presence of the isolation frame 14 helps protect the image acquisition structure 31 from vibrations that may be generated by the sound generator 21, ensuring the stability and clarity of image acquisition. This is crucial for subsequent data analysis and research on swiftlet behavior, as high-quality image data can provide more details about the swiftlet's flight patterns and movements.

[0054] Furthermore, the isolation frame 14 is roughly disc-shaped and has multiple layers. The two axial sides are made of rigid material for easy support, while the middle layer is an elastic layer that absorbs sound waves and reduces their propagation. The soft material has a certain degree of elasticity, which can help support the acquisition component 30 on top, providing some protection and support.

[0055] In some exemplary embodiments of this application, the acquisition component 30 also includes a positioning device, a temperature measurement structure, a humidity measurement structure, and a wind force measurement structure, which can realize the measurement of temperature information, wind force information, and humidity information. The positioning device can accurately determine the latitude and longitude coordinates and altitude of the portable device, which is convenient for recording the location information of the attraction point.

[0056] In some exemplary embodiments of this application, the control components inside the portable device are equipped with a wireless communication module, which can remotely control the use of functions such as playing sounds, image acquisition, and audio acquisition. This setting allows for remote control even when people are away from the portable device, reducing human traces and improving the efficiency of attracting people.

[0057] In a specific scenario, a single person can drive a vehicle and place multiple portable devices sequentially at potential locations along the optimal path. A remote operator can then use the functions of playing audible sounds, capturing images, and collecting audio to collect data. After the survey is completed, the driver can retrieve the multiple portable devices along the return path. This operation process is more convenient, and two people can conduct surveys at multiple locations.

[0058] In some exemplary embodiments of this application, the portable device is equipped with a rechargeable battery, enabling operation without a power source.

[0059] Please refer to some exemplary embodiments of this application. Figure 1 and Figure 2There are multiple first brackets 11, which are arranged in a row around the radial outside of the second bracket 12, and multiple sound generators 21 are arranged corresponding to the first brackets 11.

[0060] Multiple first brackets 11 can be used to install multiple sound generators 21 so that the swiftlet's call can be emitted in multiple directions at the same time.

[0061] The arrangement of multiple first supports 11 arranged in a circular and orderly manner ensures that the spacing between adjacent sound generators 21 is the same, resulting in sound propagation that is dispersed in all directions and has better uniformity. This arrangement also facilitates the overall support of the top isolation frame 14, which helps to improve the support effect.

[0062] In some specific application scenarios, the angle between the sound generator 21 on different first supports 11 and the horizontal plane is set differently, which can be adjusted for different environmental characteristics in that direction.

[0063] In some exemplary embodiments of this application, a plurality of first supports 11 are directly connected to the base 13, and adjacent first supports 11 do not interfere with each other.

[0064] Please refer to some exemplary embodiments of this application. Figure 1 and Figure 2 There are four first supports 11. With the position of the second support 12 as the center, the included angle between adjacent first supports 11 is 90°.

[0065] The above embodiment sets the angle between the first supports 11 in a fixed manner, which provides a good reference for the direction of sound propagation and facilitates targeted attraction.

[0066] In a specific scenario, the four first supports 11 are aligned with the four cardinal directions (north, south, east, west) or the four cardinal directions (northeast, northwest, southwest, and southeast) to achieve a specific distribution in that direction.

[0067] In some exemplary embodiments of this application, multiple first brackets 11 can be connected as one unit, and the combined body of multiple first brackets 11 is rotatably connected to the base 13, which enables the position adjustment of the speaker 21 to adapt to the sound transmission requirements of different directions.

[0068] The connection method in the above embodiments can be to set a connecting frame with an arc-shaped cross section to support the side of the first bracket 11, which can increase the structural strength and facilitate transportation.

[0069] Please refer to some exemplary embodiments of this application. Figure 1 , Figure 3 as well as Figure 6The first bracket 11 includes a first bracket plate 111 and a second bracket plate 112. The outer shell of the speaker 21 is provided with symmetrical snap-fit ​​structures 211, which are rotatably connected to the first bracket plate 111 and the second bracket plate 112 respectively.

[0070] The first support plate 111 and the second support plate 112 are configured to clamp the speaker 21, allowing the speaker 21 to rotate and its orientation to be adjusted. In specific scenarios, such as in low-lying areas, the speaker 21 needs to be oriented upwards so that the sound propagation path is mainly diagonally upwards; or in earthen slopes or mountainous areas, the speaker 21 needs to be oriented downwards so that the sound propagation path is mainly diagonally downwards.

[0071] In some exemplary embodiments of this application, a damping structure is provided between the snap-fit ​​structure 211 and the first support plate 111 and / or the second support plate 112, so that the snap-fit ​​structure 211 can maintain its angle during rotation.

[0072] In some exemplary embodiments of this application, a ratchet is provided between the snap-fit ​​structure 211 and the first support plate 111 and / or the second support plate 112.

[0073] In some exemplary embodiments of this application, the first support plate 111 and the second support plate 112 are arranged in parallel, and the snap-fit ​​structure 211 is rotatably passed through the corresponding through holes on the first support plate 111 and the second support plate 112, with the snap-fit ​​structure 211 and the through holes being interference fit.

[0074] In some exemplary embodiments of this application, the rotation angle of the snap-fit ​​structure 211 relative to the horizontal direction is between -135 degrees and 60 degrees.

[0075] The above embodiment is configured such that the snap-fit ​​structure 211 can be completely retracted between the first support plate 111 and the second support plate 112 under normal conditions, which plays a protective role during transportation and avoids damage from bumps.

[0076] When the temperature is between -135 degrees and 60 degrees, the direction of sound can be adjusted between -135 degrees and 60 degrees, and it is generally adjusted between -90 degrees and 60 degrees.

[0077] Specifically, when the angle between the snap-fit ​​structure 211 and the horizontal direction is -90 degrees, the speaker 21 is oriented vertically downwards; when the angle between the snap-fit ​​structure 211 and the horizontal direction is 0 degrees, the speaker 21 is oriented radially outwards; when the angle between the snap-fit ​​structure 211 and the horizontal direction is 45 degrees, the speaker 21 is oriented obliquely upwards, and the angle with the vertical direction is also 45 degrees.

[0078] Please refer to some exemplary embodiments of this application. Figures 2 to 4The second support 12 includes a bottom section 121, a hollow section 122 and a top section 123. The hollow section 122 is slidably fitted inside the bottom section 121, and the top section 123 is slidably fitted inside the hollow section 122. The audio acquisition structure 32 is connected to the top section 123, and the image acquisition structure 31 is movably connected to the hollow section 122.

[0079] The bottom section 121, the hollow section 122 and the top section 123 make the second support 12 form a telescopic structure, which can be extended to facilitate attraction and data collection.

[0080] Please refer to some exemplary embodiments of this application. Figures 2 to 4 The bottom section 121, hollow section 122, and top section 123 are all roughly hollow cylindrical structures. The inner diameter of the bottom section 121 is larger than the outer diameter of the hollow section 122, and the inner diameter of the bottom section 121 is clearance-fitted with the outer diameter of the hollow section 122. Similarly, the inner diameter of the hollow section 122 is larger than the outer diameter of the top section 123, and the inner diameter of the hollow section 122 is clearance-fitted with the outer diameter of the top section 123. This roughly hollow cylindrical structure provides high structural strength and can be used as an assembly reference for the acquisition component 30, thus offering high structural strength.

[0081] In some exemplary embodiments of this application, the wall thicknesses of the bottom section 121, the hollow section 122, and the top section 123 are approximately equal.

[0082] In some exemplary embodiments of this application, a limiting plate is provided at the end of the bottom section 121 away from the seat 13, and a radially outward protruding step is provided at the end of the hollow section 122 near the bottom section 121. The step is clearance-fitted with the bottom section 121, and the inner diameter of the limiting plate is clearance-fitted with the outer diameter of the hollow section 122. This arrangement allows the limiting plate and the step to form a limit position in the vertical direction, which can prevent the hollow section 122 from falling off, and at the same time play a certain sealing role to ensure that the sliding of the hollow section 122 relative to the bottom section 121 is smoother.

[0083] In some exemplary embodiments of this application, the end of the hollow section 122 away from the bottom section 121 is provided with another limiting platform, and the end of the top section 123 near the hollow section 122 is provided with another step that protrudes radially outward. The step is in clearance fit with the inner diameter of the hollow section 122, and the inner diameter of the limiting platform is in clearance fit with the outer diameter of the top section 123. This arrangement allows the limiting platform and the step to form a limit position in the vertical direction, which can prevent the top section 123 from falling off, and at the same time play a certain sealing role to ensure that the top section 123 slides more smoothly relative to the hollow section 122.

[0084] In some exemplary embodiments of this application, a first driving member is provided at the end of the hollow section 122 facing the bottom section 121, and a second driving member is provided at the end of the top section 123 facing the bottom section 121. The stroke of the first driving member is approximately half that of the second driving member.

[0085] This setting is used to control the vertical height of the hollow section 122 relative to the bottom section 121, and the vertical height of the top section 123 relative to the bottom section 121.

[0086] In some exemplary embodiments of this application, the first driving member and the second driving member may be a linear motor, or the first driving member and the second driving member may be a pneumatic cylinder, or the first driving member and the second driving member may be a motor and a threaded pair.

[0087] In some exemplary embodiments of this application, the lengths of the bottom segment 121, the hollow segment 122, and the top segment 123 are approximately equal, and the bottom segment 121 can be completely located within the hollow segment 122, and the hollow segment 122 can be completely located within the top segment 123, resulting in a more compact structure.

[0088] Please refer to some exemplary embodiments of this application. Figure 3 and Figure 5 The acquisition component 30 also includes a connecting bracket 33. Multiple image acquisition structures 31 are arranged in a row around the connecting bracket 33. The hollow section 122 has external threads on its radially outer side, and the connecting bracket 33 is threadedly connected to the hollow section 122. The threaded connection ensures the stability of the connection between the connecting bracket 33 and the hollow section 122, and also allows for more precise adjustment of the horizontal position and vertical height of the connecting bracket 33.

[0089] The connecting bracket 33 is provided with a base 331, a radial displacement structure 332, an axial displacement structure 333, and an angular displacement structure 334 for adjusting the specific shape of the image acquisition structure 31. The image acquisition structure 31 is fixedly connected to the angular displacement structure 334.

[0090] Specifically, the radial displacement structure 332 is disposed within the sliding groove of the base 331 and can slide radially outward, thereby moving the axial displacement structure 333. The axial displacement structure 333 includes a slide rail and a slider. The slide rail is arranged vertically, and the slider is connected to the angular displacement structure 334. The angular displacement structure 334 can rotate relative to the slider to adjust the orientation of the image acquisition structure 31.

[0091] The above settings enable multiple degrees of freedom in the image acquisition structure 31, facilitating continuous motion capture of swiftlets.

[0092] In some exemplary embodiments of this application, the image acquisition structure 31 is a high-speed camera. The high-speed camera is designed to capture images at a high frame rate, thereby recording in detail the rapid flight movements and subtle behaviors of swiftlets, providing strong technical support for behavioral research and conservation efforts of swiftlets.

[0093] Please refer to some exemplary embodiments of this application. Figure 3 and Figure 4 The top section 123, away from the hollow section 122, has a receiving space, within which the audio acquisition structure 32 is retractably mounted. This retractable design allows the audio acquisition structure 32 to extend out of the receiving space when audio acquisition is needed, and to retract back into the receiving space when acquisition is not required or when protection of the acquisition structure is necessary. This design improves the adaptability and flexibility of the device.

[0094] The retractable design of the audio acquisition structure 32, housed within the top section 123, not only enhances the portability and ease of operation of the device but also strengthens the protection of the acquisition structure, enabling the device to adapt to various usage environments and needs. This design provides an effective solution for audio acquisition of swiftlets, helping to improve the quality and efficiency of audio data acquisition.

[0095] Please refer to some exemplary embodiments of this application. Figure 3 and Figure 4 The accommodating space includes a first accommodating space 124 and a second accommodating space 125. The first accommodating space 124 is located on the axial end face of the top segment 123 away from the hollow segment 122, and the second accommodating spaces 125 are arranged in an array and surrounding the radial outer side of the top segment 123. This arrangement provides the audio acquisition structure 32 with a flexible and omnidirectional telescopic configuration, enabling the device to adapt to various different audio acquisition needs.
