Description

Technical Field

[0001] The present invention relates to the technical field of wildlife research, and in particular to a dynamic camouflaged wildlife passage monitoring device and method based on multimodal perception. Background Art

[0002] With the continued expansion of global transportation infrastructure, the problem of wildlife habitat fragmentation has become increasingly serious; this fragmentation has directly led to the obstruction of animal migration routes, increased the frequency of roadkill accidents, and posed a major threat to biodiversity and ecological balance; to alleviate this problem, various types of wildlife corridors (such as ecological bridges, underground culverts, etc.) have been widely adopted and applied in actual conservation work, aiming to restore and maintain natural migration routes between species.

[0003] To maintain the normal operation of wildlife passages, monitoring is necessary to ensure that abnormal situations can be dealt with in a timely manner (such as landslides and animal conflicts that lead to access obstacles). In practice, it has been found that although these passages have been established, the utilization rate of wildlife is often low, and the monitoring devices lack effective guidance facilities to increase the enthusiasm of animals to use them. In addition, the design of traditional wildlife passages mostly uses fixed concrete structures, which fails to fully consider the behavioral preferences of different species. For example, large cats such as the North China leopard tend to choose open paths with good visibility to move; small mammals and reptiles require a more concealed environment to feel safe, and cannot be adjusted and guided according to the monitoring information, which affects the utilization rate of animal passages. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1 , a dynamic camouflage wildlife passage monitoring device based on multimodal perception, comprising: a monitoring device 1 and a passage shielding component installed in an animal passage 2;

[0033] Among them, see Figure 1 The monitoring device 1 includes a dynamic simulation component 101 and a multimodal monitoring component 102; the dynamic simulation component 101 includes a shell and a camouflage layer and a bionic coating sequentially arranged on the outside of the shell. The camouflage layer uses a thermochromic or liquid crystal film to adjust the camouflage color according to the temperature changes during the day and night, so that the device can better integrate into the environment and prevent animals from being overly alert; the bionic coating uses a texture coating (imitation bark, rock) + anti-reflective coating to reduce the reflection of the device in the sun, making it more difficult for animals to detect; the multimodal monitoring component 102 includes an infrared and thermal imaging dual sensor (avoiding the use of traditional visible light cameras to prevent night flashes or infrared fill light from disturbing animals). The multimodal monitoring component 102 is installed inside the shell, and dual monitoring is used to achieve multimodal perception;

[0034] It should be noted that the dynamic simulation component 101 can be made into a tree shape or a stone shape; the multimodal monitoring component 102 is provided by solar power generation, and the photovoltaic power generation equipment can be installed on the dynamic simulation component 101 or in other areas; the multimodal monitoring component 102 is also equipped with a controller (such as a PLC control);

[0035] See also Figure 1 、 Figure 2 and Figure 3The channel blocking component includes a storage component 3, a flexible barrier 4 and a driving component 5; the storage component 3 includes a storage box, a winding roller rotatably arranged in the inner cavity of the storage box, and a torsion spring arranged between the storage box and the winding roller, the flexible barrier 4 is wound on the outer wall of the winding roller, and the flexible barrier 4 extends to the outside of the storage box at one end away from the winding roller. The flexible barrier 4 is a flexible metal plate, and the surface of the flexible metal plate is covered with a matte anti-reflective composite material; there are two driving components 5, which are respectively located on the upper and lower sides of the storage component 3, and the two driving components 5 are respectively installed on the upper and lower sides of the animal channel 2; the driving component 5 includes a guide groove 51, a driving motor 54 installed in the inner cavity of the guide groove 51, a screw 53 provided on the output shaft of the driving motor 54, and a screw sleeve 52 arranged on the outer wall of the screw 53, the screw sleeve 52 is slidably installed in the inner cavity of the guide groove 51, and the screw sleeve 52 is connected to the end of the flexible barrier 4 away from the winding roller.

[0036] It should be noted that there can be two storage components 3 and flexible blocking members 4, and the two storage components 3 are respectively installed on the left and right sides of the entrance of the animal passage 2; in order to enable the flexible blocking members 4 on both sides to move, two screw sleeves 52, screws 53 and drive motors 54 are symmetrically installed inside a guide groove 51.

[0037] A dynamic camouflaged wildlife channel monitoring method based on multimodal perception is as follows:

[0038] First, the multimodal monitoring component 102 of the monitoring device 1 collects information (species and quantity) of wild animals approaching the animal passage 2;

[0039] Second, when a predetermined category of wild animal is detected (i.e., an animal that needs to adjust the width of the animal passage 2 is detected), the controller controls the drive motor 54 of the drive member 5 to work, drives the screw 53 to rotate, causes the screw sleeve 52 to slide in the inner cavity of the guide groove 51, pulls the flexible barrier 4, and pulls it out from the interior of the storage component 3 to narrow the entrance of the animal passage 2, or the controller controls the drive motor 54 of the drive member 5 to work, drives the screw 53 to reverse, causes the screw sleeve 52 to slide in the inner cavity of the guide groove 51, and pushes the flexible barrier 4 toward the interior of the storage component 3 to widen the entrance of the animal passage 2.

[0040] It should be noted that when a wild animal requiring a wide passage space is detected approaching the animal passage 2, if the entrance of the animal passage 2 is in the widest state at this time, the passage shielding component will not work.

[0041] In this embodiment, as a further optimization solution, please refer to Figure 3 and Figure 4The opening of the upper guide groove 51 faces downward, so that impurities will accumulate inside the upper guide groove 51, and the opening of the lower guide groove 51 faces the outlet of the animal passage 2; a cleaning piece 55 (brush) is provided on the side wall of the lower screw sleeve 52. When the screw 53 rotates to drive the screw sleeve 52 to slide inside the guide groove 51, the cleaning piece 55 will clean the surface of the screw 53, reducing the probability of impurities adhering to the surface of the screw 53, so that the screw 53 can rotate and move the screw sleeve 52 normally. Scrapers 56 are installed on the front and rear sides of the moving direction of the screw sleeve 52. The scraper 56 is in contact with the bottom of the inner cavity of the lower guide groove 51 and is used to clean impurities at the bottom of the inner cavity of the guide groove 51 to ensure the normal operation of the lower driving member 5.

[0042] In this embodiment, as a further optimization solution, please refer to Figure 1 A warning device 7 is provided on the outside of the animal passage 2. The warning device 7 includes a column, an LED warning sign installed on the column and a magnetic sensor. The magnetic sensor is deployed on the road around the animal passage 2. When a vehicle approaches, the LED warning sign is triggered (displaying "Animal passing, slow down and do not honk").

[0043] Example 2

[0044] As a further optimization solution of Example 1, please refer to Figure 1 、 Figure 2 and Figure 5 The monitoring device also includes a sound guidance device 6, which is installed at the top of the inner cavity of the animal passage 2. The sound guidance device 6 includes a mounting shell and a speaker and a processor arranged inside the mounting shell. An indicator light 10 is installed at the bottom of the mounting shell (using a red LED light source with a wavelength of > 600nm, which automatically lights up the path of the animal passage 2 at night); when wild animals are detected approaching the animal passage, the processor controls the speaker to produce a sound (such as the call of a cub, a mating signal), which is played through the directional speaker to guide the wild animals to actively approach the animal passage 2.

[0045] It should also be noted that when a vehicle approaches animal passage 2, the speaker activates low-frequency sound waves (below the animal's hearing sensitivity threshold) to offset vehicle noise and reduce interference with wildlife animals.

[0046] As a further optimization solution of Example 1, please refer to Figure 2 and Figure 5A slide rail 8 is installed on the top of the inner cavity of the animal passage 2, and a walking component (including a motor and a roller installed on the motor output shaft) is provided on the side wall of the sound guide device 6, and the roller is located in the inner cavity of the slide rail 8; a detector 11 (such as a laser radar) is provided on the sound guide device 6; the detector 11 is used to detect the distance between the wild animal and the sound guide device 6. When the distance is less than the threshold (a pre-set distance), the processor controls the motor of the walking component to start, so that the roller moves on the slide rail 8, so that the sound guide device 6 moves toward the exit of the animal passage 2, so that the sound guide device 6 plays a role in guiding the wild animal to pass through the animal passage 2, and the detector 11 will continuously collect the position of the wild animal, so that the processor controls the walking component to speed up, slow down or stop, thereby increasing the accuracy of the guidance.

[0047] It should be noted that, if a group of wild animals passes through the animal passage 2 , the detector 11 will detect the distance between the leading animal and the sound guidance device 6 .

[0048] In this embodiment, as a further optimization solution, please refer to Figure 2 、 Figure 5 and Figure 6 , a driving assembly 9 is provided at the end of the slide rail 8; the driving assembly 9 includes a bell body 91, a sleeve 92, an impact ball 95, a knocking block 93, and an elastic reset member 94 (spring); the bell body 91 is mounted on the side wall of the slide rail 8, the sleeve 92 is mounted at the bottom of the slide rail 8, one end of the sleeve 92 is in contact with the side wall of the bell body 91, the knocking block 93 is slidably arranged in the inner cavity of the sleeve 92, the elastic reset member 94 is arranged between the knocking block 93 and the sleeve 92, the impact ball 95 is in the inner cavity of the sleeve 92 and between the knocking block 93 and the bell body 91, an electromagnet 12 is provided on the side wall of the sound guide device 6, the knocking block 9 3 is made of a metal material that can be magnetically attracted, such as iron; when the sound guide device 6 moves to the end of the slide rail 8, the electromagnet 12 is energized to generate a magnetic force, which is used to attract the knocking block 93 to move closer to the sound guide device 6 and compress the elastic reset member 94; then the electromagnet 12 is de-energized, so that the magnetic attraction force on the knocking block 93 disappears, and at this time the elastic reset member 94 will quickly reset the knocking block 93 and hit the impact ball 95, so that the impact ball 95 collides with the bell body 91 to produce a sound, which plays a role in driving away wild animals inside the animal passage 2 and preventing wild animals from staying inside the animal passage 2.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
