Description

Technical Field

[0001] This invention belongs to the technical field of bird diversity monitoring equipment, specifically relating to an identification device for assessing bird species diversity in protected areas or habitats. Background Technology

[0002] AI recognition combined with infrared cameras represents a new technology for wildlife monitoring, boasting high accuracy and sensitivity. Traditional cameras rely solely on image analysis for monitoring, whereas AI recognition combined with infrared cameras combines intelligent algorithms with infrared technology, enabling accurate monitoring and identification even in dark or complex environments. Furthermore, its filtering algorithms reduce false positives for non-target objects, making the monitoring results more reliable.

[0003] In existing technologies, a large number of infrared cameras are densely deployed in various natural ecological zones or habitats to collect massive amounts of image data. However, infrared cameras are usually placed in fixed locations to collect information, and the following problems often occur in the actual information acquisition process:

[0004] (1) Since the herbaceous layer in natural ecological areas or habitats is relatively lush, and the lens is generally placed in the open, long-term monitoring will cause the lens to be scratched by plants, and the lens is prone to stains. In the existing technology, staff often need to wipe the lens, which wastes manpower and resources.

[0005] (2) In the existing technology, infrared cameras are often used for fixed-point shooting. Even if the camera has an ultra-wide-angle lens, there are still certain blind spots in the field of view during monitoring, which leads to low efficiency in identifying the diversity of birds in the protected area. Summary of the Invention

[0006] The purpose of this invention is to provide an identification device for assessing bird species diversity in protected areas or habitats, in order to solve the problems mentioned in the background art.

[0007] The present invention achieves the above objectives through the following technical solutions:

[0008] A device for assessing bird species diversity in a protected area or habitat includes an installation unit, a monitoring unit located at the upper end of the installation unit, and a lidar located at the upper end of the monitoring unit. The monitoring unit and the lidar are controlled to rotate by a motor and a motor, respectively, to monitor bird activity.

[0009] An infrared camera is provided on the outer end face of the monitoring unit, and a lens cleaning mechanism and a liquid storage tank are provided on the upper end of the infrared camera; the lens cleaning mechanism includes a box body, a liquid channel provided in the box body, a spray nozzle provided at the lower end of the liquid channel, and a pressure relief valve provided on the spray nozzle.

[0010] The monitoring unit is equipped with a pressurizing component that communicates with the lens cleaning mechanism. The pressurizing component includes a gas chamber that communicates with the liquid channel and a transmission component that is connected to the second output end of the motor. When the transmission component moves downward, it increases the gas pressure in the gas chamber and simultaneously increases the pressure inside the liquid channel, causing the internal liquid to be sprayed from the nozzle onto the infrared camera to complete the lens cleaning of the infrared camera.

[0011] As a further optimization of the present invention, the pressurizing component further includes a slider disposed at the lower end of the transmission component. The transmission component drives the slider to move within the monitoring unit. A guide rod is disposed within the monitoring unit along the slider's moving direction. A sliding sleeve is fitted onto the guide rod. One side of the sliding sleeve is fixedly connected to the slider, and the other side of the slider is fixedly connected to a right-angle connecting rod. A protruding cavity is provided at the upper end of the gas chamber. A piston plate is disposed within the protruding cavity, and the upper end of the piston plate is fixedly connected to the end of the right-angle connecting rod.

[0012] As a further optimization of the present invention, the transmission assembly includes an annular bushing connected to the second output end of the motor and a driven shaft that movably abuts against the annular bushing. Both the annular bushing and the driven shaft are provided with limiting portions, and each of the two limiting portions has an arc-shaped protrusion on its opposite side.

[0013] As a further optimization of the present invention, a second protruding cavity is symmetrically provided in the liquid channel along the liquid flow direction. A threaded portion is provided in the second protruding cavity located on one side of the liquid channel. An adjusting knob is threadedly connected to the second protruding cavity through the threaded portion. The adjusting end of the adjusting knob extends to the outer end of the second protruding cavity.

[0014] As a further optimization of the present invention, the liquid channel and the gas chamber are connected by a pressure-changing channel, which is a pipe design that gradually narrows from the middle to both ends, and a one-way valve is provided in the middle of the pressure-changing channel.

[0015] As a further optimization of the present invention, the output end of the motor is provided with a driving gear, the fixed end of the laser radar is provided with a driven gear that meshes with the driving gear, the central shaft end of the driven gear is connected to a reducer, and the output end of the reducer is connected to the annular bushing for transmission.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) This invention enables the motor 2 to drive the laser radar to monitor the spatial location information of birds in real time, while also linking the pressurization component to work, so that the liquid channel in the lens cleaning mechanism can be pressurized, and the cleaning fluid can be sprayed out periodically, realizing the periodic self-cleaning of the infrared camera lens. There is no need for the control circuit and control program of the external nozzle spraying cleaning fluid, which reduces the cost of the device and reduces the overall power consumption of the device, increasing the outdoor battery life of the identification device.

[0018] 2) This invention achieves the priority of identifying the spatial location information of birds in the protected area through lidar, and then controlling the infrared camera to rotate through the controller. The infrared camera accurately acquires images of birds in flight, and then obtains the species category of the bird. Compared with the existing technology of using infrared cameras to take pictures at fixed points, there are no blind spots in the field of view, and there is no need to deploy multiple identification devices, resulting in lower identification costs.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above-described contents.

[0027] Example 1

[0028] like Figure 1-6As shown, this embodiment proposes an identification device for assessing bird species diversity in protected areas or habitats, including an installation part 1, a monitoring part 2 located at the upper end of the installation part 1, and a lidar 3 located at the upper end of the monitoring part 2. The monitoring part 2 and the lidar 3 are controlled to rotate by motor 5 and motor 9, respectively, to monitor bird activity.

[0029] Monitoring Unit 2 enables automatic patrol and capture of surrounding birds and intelligent identification. Through deep learning algorithms, it extracts various bird physical features, enabling real-time multi-target capture and automatic identification and classification of moving birds in video footage. It supports bird discovery and identification, image reporting, automatic push notifications to the monitoring platform, and designated mobile phone message push notifications.

[0030] The assessment and identification device also includes a controller 6 located at the lower end of the monitoring unit 2. The controller 6 has a built-in logic control program. In this embodiment, the lidar 3 is driven by motor 2 9 to rotate around the clock. When the lidar 3 detects bird activity at a certain spatial location of the assessment and identification device, the lidar 3 transmits the signal to the controller 6. After receiving the signal, the controller 6 controls motor 1 5 to work, so that motor 1 5 drives the monitoring unit 2 to rotate to the pre-received azimuth angle, so that the infrared camera 4 located on the monitoring unit 2 can accurately acquire bird flight images, and then obtain the species category of the bird.

[0031] It should be noted that, in this invention, after the lidar 3 acquires the spatial position information of the flying bird during its rotation, it transmits the spatial position information to the controller 6. The controller 6 then quickly controls the motor 5 to work based on the spatial position information so that the infrared camera 4 is ready to be aligned with the azimuth angle. In this invention, the lidar 3 is used to acquire high-precision, high-resolution spatial position information of bird targets.

[0032] An infrared camera 4 is provided on the outer end face of the monitoring unit 2. A lens cleaning mechanism 7 and a liquid storage tank 8 are provided on the upper end of the infrared camera 4. The liquid storage tank 8 is periodically filled with camera lens cleaning fluid. The lens cleaning mechanism 7 includes a box 71, a liquid channel 72 located in the box 71, a spray nozzle 73 located at the lower end of the liquid channel 72, and a pressure relief valve 75 located on the spray nozzle 73. When the liquid pressure in the spray nozzle 73 reaches the preset pressure value of the pressure relief valve 75, the spray nozzle 73 begins to spray cleaning fluid onto the camera lens. The liquid storage tank 8 and the liquid channel 72 are connected through a conduit 81.

[0033] The monitoring unit 2 is equipped with a pressurizing component that is connected to the lens cleaning mechanism 7. The pressurizing component includes a gas chamber 27 that is connected to the liquid channel 72 and a transmission component 22 that is connected to the output end of the motor 2 9. When the transmission component 22 moves downward, it increases the gas pressure in the gas chamber 27. The pressure inside the liquid channel 72 increases simultaneously, causing the internal liquid to be sprayed from the spray nozzle 73 onto the infrared camera 4 to complete the lens cleaning of the infrared camera 4.

[0034] refer to Figure 2 Preferably, the pressurizing assembly also includes a slider 23 located at the lower end of the transmission assembly 22. The transmission assembly 22 drives the slider 23 to move within the monitoring unit 2. A guide rod 24 is provided within the monitoring unit 2 along the moving direction of the slider 23. A sliding sleeve 25 is fitted on the guide rod 24. A damping spring is fitted on the guide rod 24 located at the lower end of the sliding sleeve 25. One side of the sliding sleeve 25 is fixedly connected to the slider 23, and the other side of the slider 23 is fixedly connected to a right-angle connecting rod 26. A protruding cavity 28 is provided at the upper end of the gas chamber 27. A piston plate 29 is provided inside the protruding cavity 28. The upper end of the piston plate 29 is fixedly connected to the end of the right-angle connecting rod 26.

[0035] refer to Figure 1 -4. In this embodiment, when the slider 23 moves downward via the transmission component 22, the sliding sleeve 25 can drive the right-angle connecting rod 26 and the piston plate 29 to move downward, thereby pressurizing the gas in the gas chamber 27. The gas chamber 27 is connected to the liquid channel 72, and the pressure inside the liquid channel 72 increases synchronously, causing the internal liquid to be sprayed from the spray nozzle 73 onto the infrared camera 4 to complete the lens cleaning of the infrared camera 4. This invention enables the motor 29 to drive the lidar 3 to monitor the spatial location information of birds in real time, while also linking the pressurization component to work, so that the liquid channel 72 inside the lens cleaning mechanism 7 is pressurized, and the cleaning fluid can be sprayed out periodically, realizing the periodic self-cleaning of the lens of the infrared camera 4. There is no need for the control circuit and control program of the external nozzle spraying cleaning fluid, which reduces the cost of the device and the overall power consumption of the device, and increases the outdoor battery life of the identification device.

[0036] refer to Figure 5-6 Preferably, the transmission assembly 22 includes an annular bushing 221 connected to the output end of the motor 29, and a driven shaft 222 that movably abuts against the annular bushing 221. Both the annular bushing 221 and the driven shaft 222 are provided with limiting parts 223, and each of the two limiting parts 223 is provided with an arc-shaped protrusion 224 on the opposite side.

[0037] In this embodiment, when motor 29 rotates, it drives the annular bushing 221 to rotate synchronously. The limiting part 223 on the driven shaft 222 is located between two adjacent limiting parts 223 on the annular bushing 221. The opposite sides of the limiting part 223 on the driven shaft 222 and the limiting part on the annular bushing 221 are both inclined surfaces. Therefore, when the annular bushing 221 rotates, due to the squeezing action of the inclined surface and the limiting action of the guide rod 24, the driven shaft 222 experiences friction and squeezing on the inclined surface. Under pressure, the lens moves downward, causing the right-angle connecting rod 26 to move downward. Once the pressure reaches the preset pressure value of the pressure relief valve 75, the lens cleaning mechanism 7 completes one cleaning fluid spray. The slider 23 and the driven shaft 222 reset under the elastic force of the damping spring on the guide rod 24. In conjunction with the arc-shaped protrusion 224 at the front end of the limiting part 223, the limiting part 223 on the driven shaft 222 quickly engages again between the two adjacent limiting parts 223 on the annular bushing 221. During the above process, the motor 29 works continuously to drive the lidar 3 for real-time monitoring. The transmission component 22, the pressurizing component, and the lens cleaning mechanism 7 perform transmission, pressurization, and spraying actions in sequence according to the continuous cycle of the motor 29, thereby achieving the periodic cleaning of the camera lens of the infrared camera 4 through the motor 29 as the active component.

[0038] refer to Figure 4 Preferably, two protruding cavities 76 are symmetrically arranged within the liquid channel 72 along the liquid flow direction. These two protruding cavities 76 form a pressure-changing section within the liquid channel 72. One of the protruding cavities 76 located on one side of the liquid channel 72 has a threaded portion, and an adjusting knob 77 is threadedly connected to this portion. The adjusting end of the adjusting knob 77 extends to the outer end of the protruding cavity 76. In use, the position of the adjusting knob 77 within the protruding cavity 76 can be adjusted by manually rotating it, thereby fine-tuning the liquid pressure inside the liquid channel 72 and consequently fine-tuning the spraying time of the lens cleaning mechanism 7.

[0039] Preferably, the liquid channel 72 and the gas chamber 27 are connected by a pressure-changing channel 74, which is a pipe design that gradually narrows from the middle to both ends, and a one-way valve is provided in the middle of the pressure-changing channel 74.

[0040] Preferably, the output end of the motor 29 is provided with a drive gear, and the fixed end of the lidar 3 is provided with a driven gear that meshes with the drive gear. The central shaft end of the driven gear is connected to a reducer 21, and the output end of the reducer 21 is connected to the annular bushing 221 for transmission. By setting the reducer 21, the rotational speed of the annular bushing 221 relative to the lidar 3 can be reduced, preventing the lens cleaning mechanism 7 from having too short a spraying cycle when the rotational speed of the annular bushing 221 is too fast.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
