Description

Technical Field

[0001] This invention relates to the field of wildlife research technology, specifically to a dynamic camouflage wildlife passage monitoring device and method based on multimodal perception. Background Technology

[0002] With the continuous expansion of global transportation infrastructure, the fragmentation of wildlife habitats has become increasingly serious. This fragmentation directly leads to the obstruction of animal migration routes, increases the frequency of roadkill incidents, and poses a significant threat to biodiversity and ecological balance. To alleviate this problem, various wildlife corridors (such as ecological bridges and underground culverts) have been widely adopted and applied in practical conservation work, aiming to restore and maintain natural migration routes between species.

[0003] To maintain the normal operation of wildlife corridors, monitoring is necessary to ensure timely handling of any abnormal situations (such as landslides or animal conflicts causing passage obstacles). In practice, it has been found that although these corridors have been established, wildlife utilization rates are often low. Monitoring devices lack effective guidance facilities to improve animal participation. Furthermore, traditional wildlife corridor designs often use fixed concrete structures, failing to fully consider the behavioral preferences of different species. For example, large felines like the North China leopard tend to choose open paths with good visibility, while smaller mammals and reptiles require more concealed environments to feel safe. The inability to adjust guidance based on monitoring information further impacts the utilization rate of animal corridors. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamic camouflage-based wildlife passage monitoring device and method based on multimodal perception, in order to solve the problem mentioned in the background art of the lack of effective guidance facilities to improve the animals' willingness to use the monitoring devices.

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1 A dynamic camouflage-based wildlife passage monitoring device based on multimodal perception includes: a monitoring device 1 and a passage shielding component installed in the animal passage 2;

[0033] Please refer to 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 biomimetic coating sequentially disposed on the outside of the shell. The camouflage layer uses thermochromic or liquid crystal film to adjust the camouflage color according to the temperature changes between day and night, so that the device can better blend into the environment and avoid animals being too alert. The biomimetic coating uses a textured coating (imitating tree bark and rocks) + an anti-reflective coating to reduce the reflection of the device in sunlight, making it more difficult for animals to find. The multimodal monitoring component 102 includes infrared and thermal imaging dual sensors (avoiding the use of traditional visible light cameras to prevent night flashes or infrared supplemental lighting from disturbing animals). The multimodal monitoring component 102 is installed inside the shell, and the dual monitoring is used to achieve multimodal perception.

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

[0035] Please see Figure 1 , Figure 2 and Figure 3The passage blocking assembly includes a storage component 3, a flexible blocking component 4, and a driving component 5. The storage component 3 includes a storage box, a take-up roller rotatably disposed in the inner cavity of the storage box, and a torsion spring disposed between the storage box and the take-up roller. The flexible blocking component 4 is wound around the outer wall of the take-up roller, and the end of the flexible blocking component 4 away from the take-up roller extends to the outside of the storage box. The flexible blocking component 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 located on the upper and lower sides of the storage component 3, and are installed on the upper and lower sides of the animal passage 2, respectively. The driving component 5 includes a guide groove 51, a drive motor 54 installed in the inner cavity of the guide groove 51, a screw 53 disposed on the output shaft of the drive motor 54, and a screw sleeve 52 sleeved 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 blocking component 4 away from the take-up roller.

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

[0037] A dynamic camouflage-based wildlife corridor monitoring method based on multimodal perception is described below:

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

[0039] Second, when a predetermined type of wild animal is detected (i.e., an animal for which the width of the animal passage 2 needs to be adjusted), the controller controls the drive motor 54 of the drive unit 5 to work, causing the screw 53 to rotate, so that the screw sleeve 52 slides in the inner cavity of the guide groove 51, pulling the flexible blocking member 4 out from the inside of the receiving assembly 3, so as to narrow the entrance of the animal passage 2. Alternatively, the controller controls the drive motor 54 of the drive unit 5 to work, causing the screw 53 to reverse, so that the screw sleeve 52 slides in the inner cavity of the guide groove 51, pushing the flexible blocking member 4 into the receiving assembly 3, so as to widen the entrance of the animal passage 2.

[0040] It should be noted that when a wild animal requiring ample passage is detected approaching animal passage 2, if the entrance to animal passage 2 is at its widest position at this time, the passage blocking component will not work.

[0041] In this embodiment, as a further optimization, please refer to... Figure 3 and Figure 4The opening of the upper guide groove 51 faces downward, causing impurities to accumulate inside the upper guide groove 51. The opening of the lower guide groove 51 faces the exit of the animal passage 2. A cleaning component 55 (brush) is provided on the side wall of the lower screw sleeve 52. When the screw 53 rotates and drives the screw sleeve 52 to slide inside the guide groove 51, the cleaning component 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 both the front and rear sides of the moving direction of the screw sleeve 52. The scrapers 56 fit against the bottom of the inner cavity of the lower guide groove 51 and are used to clean the impurities at the bottom of the inner cavity of the guide groove 51, ensuring that the lower drive component 5 works normally.

[0042] In this embodiment, as a further optimization, please refer to... Figure 1 The animal passage 2 is equipped with a warning device 7 on its outer side. The warning device 7 includes a post, an LED warning sign installed on the post, and a magnetic sensor. The magnetic sensor is deployed on the road around the animal passage 2. When a vehicle approaches, it triggers the LED warning sign (displaying "Animal passing by, slow down and do not honk").

[0043] Example 2

[0044] As a further optimization 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 housing and a speaker and processor located inside the mounting housing. An indicator light 10 (using a red LED light source with a wavelength > 600nm, which automatically illuminates the path of the animal passage 2 at night) is installed at the bottom of the mounting housing. When a wild animal is detected approaching the animal passage, the processor controls the speaker to emit a sound (such as the call of cubs or mating signals), which is played through the directional speaker to guide the wild animal to actively approach the animal passage 2.

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

[0046] As a further optimization of Example 1, please refer to Figure 2 and Figure 5The animal passage 2 has a slide rail 8 installed at the top of its inner cavity. The sound guidance device 6 has a walking component (including a motor and rollers mounted on the motor output shaft) on its side wall. The rollers are located in the inner cavity of the slide rail 8. The sound guidance device 6 has a detector 11 (such as a lidar). The detector 11 is used to detect the distance between the wild animal and the sound guidance device 6. When the distance is less than a threshold (a preset distance), the processor controls the motor of the walking component to start, so that the rollers can walk on the slide rail 8, so that the sound guidance device 6 can move towards the exit of the animal passage 2. The sound guidance device 6 can guide the wild animal through the animal passage 2. The detector 11 will continuously collect the position of the wild animal, so that the processor can control the walking component to speed up, slow down or stop, increasing the accuracy of guidance.

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

[0048] In this embodiment, as a further optimization, 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 striking block 93, and an elastic reset member 94 (spring); the bell body 91 is installed on the side wall of the slide rail 8, the sleeve 92 is installed 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 striking block 93 is slidably disposed in the inner cavity of the sleeve 92, the elastic reset member 94 is disposed between the striking block 93 and the sleeve 92, the impact ball 95 is located in the inner cavity of the sleeve 92 and is located between the striking block 93 and the bell body 91, and an electromagnet 12 is provided on the side wall of the sound guiding device 6, the striking block 95 is disposed in the inner cavity of the sleeve 92 and between the striking block 93 and the bell body 91, and the sound guiding device 6 is provided with an electromagnet 12 on the side wall, the striking block 95 is disposed in the inner cavity of the sleeve 92 and between the striking block 93 and the bell body 91, and the sound guiding device 6 is provided with an electromagnet 12, the striking block 95 is disposed in the inner cavity of the sleeve 92 and between the striking block 93 and the bell body 91, and the sound guiding device 6 is provided with an electromagnet 94. 3 is made of a metal material that can be magnetically attracted, such as iron; when the sound guiding 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 striking block 93 to move towards the sound guiding device 6 and compress the elastic reset member 94; then the electromagnet 12 is de-energized, so that the magnetic attraction of the striking block 93 disappears. At this time, the elastic reset member 94 will quickly reset the striking block 93 and strike the striking ball 95, so that the striking ball 95 and the bell body 91 will collide 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] 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.
