Description

Technical Field

[0001] This invention relates to the field of ecological corridor planning and monitoring technology, specifically to a remote sensing image acquisition device and method based on ecological corridor classification. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of population, the urban ecological environment is facing unprecedented challenges. Among them, ecological corridors, as important channels connecting ecological patches within the city, play an irreplaceable role in maintaining urban ecological balance, promoting biodiversity, and improving the quality of life of urban residents. In the planning and monitoring of ecological corridors, remote sensing images of the target area are generally collected using equipment. Specifically, this involves using drones equipped with cameras to collect remote sensing images of the target area. For example, a device for collecting remote sensing images using a drone is disclosed in the public document with announcement number CN220884841U.

[0003] However, the device has certain limitations in use. For example, the wiping block is prone to moisture adhesion when exposed to the outside environment. Furthermore, with repeated use (the wiping block needs to wipe the camera lens multiple times during drone flight), moisture accumulates on the wiping block. This causes the wiping block to squeeze the moisture onto the camera lens during wiping, resulting in the camera lens not being clean. Consequently, the clarity of the remote sensing images acquired affects the planning and monitoring of ecological corridors. Summary of the Invention

[0004] The purpose of this invention is to provide a remote sensing image acquisition device and method based on the classification of ecological corridor levels, so as to solve the problem mentioned in the background art where the wiping block accumulates moisture, causing the wiping block to squeeze the moisture it carries onto the camera lens during the wiping process, resulting in the camera lens not being clean and thus affecting the clarity of the acquired remote sensing images.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote sensing image acquisition device based on the classification of ecological corridor levels, comprising: a drone and an acquisition end mounted on the drone for acquiring remote sensing images of ecological corridors of the target level, wherein the drone is provided with a drive motor, the output end of the drive motor is provided with an mounting arm, and the mounting arm is provided with a cleaning block for wiping the lens of the acquisition end.

[0006] The drone is equipped with a replacement component;

[0007] The replacement component includes a mounting component, which has a movable frame for filling spare wiping blocks, and a replacement component for discharging spare wiping blocks from the movable frame.

[0008] The drone is equipped with a feeding component. After the feeding component removes the wiping block from the mounting arm, the replacement component discharges the spare wiping block inside the moving frame and installs it on the mounting arm.

[0009] Preferably, the mounting component is provided with a first telescopic component for driving the moving frame to rise and fall. There are several spare cleaning blocks, which are placed sequentially from top to bottom in the inner cavity of the moving frame. The inner side wall of the moving frame is provided with a mounting groove. The replacement component includes a second telescopic component disposed in the mounting groove. The moving end of the second telescopic component is provided with a limiting block. The side wall of the spare cleaning block is provided with a limiting groove, and the limiting block is inserted into the limiting groove of the lower spare cleaning block. When the mounting arm rotates to the bottom of the moving frame, the first telescopic component drives the moving frame to move down to a predetermined position. The second telescopic component moves out of the limiting groove with the limiting block, releasing the restriction on the spare cleaning block. Under the action of gravity, the lowermost spare cleaning block will contact the mounting arm.

[0010] Preferably, the wiping block has the same structure as the spare wiping block;

[0011] The spare wiping block includes a base and a cleaning block mounted on the base. The base is equipped with an electromagnet for attracting the mounting arm. A storage groove is provided at the bottom of the base. A moving block and an elastic element connected to the moving block are slidably arranged in the storage groove. A first touch switch located on the moving path of the moving block and used to control the electromagnet to be energized is provided in the storage groove. A second touch switch is provided on the side wall of the base for controlling the electromagnet to be de-energized. The unloading component is a baffle, which is located on the moving path of the wiping block and used to press the second touch switch.

[0012] Preferably, the base has a mounting groove at its bottom, the electromagnet is slidably disposed in the mounting groove, a spring is provided between the electromagnet and the mounting groove, a magnetic block is provided in the mounting groove to repel the electromagnet to the outside of the mounting groove, and a slot is provided on the mounting arm; when the first touch switch controls the electromagnet to be energized and generate magnetic force, the electromagnet and the magnetic block repel each other, causing the electromagnet to be inserted into the slot.

[0013] Preferably, a slot is provided on the side wall of the base, the second touch switch is slidably disposed in the slot, and an elastic element is provided between the slot and the second touch switch.

[0014] Preferably, the drone is equipped with a mounting box, and the drive motor, mounting components and unloading components are all housed inside the mounting box. An opening is provided on the side wall of the mounting box for the mounting arm and the wiping block to pass through.

[0015] Preferably, the mounting arm includes a support arm disposed on the output shaft of the drive motor and a movable arm disposed on the support arm. The support arm is provided with a drive component for driving the movable arm to move, and the rubbing block is mounted on the movable arm.

[0016] As a preferred embodiment, the remote sensing image acquisition method based on ecological corridor classification, utilizing the aforementioned remote sensing image acquisition device based on ecological corridor classification, includes the following steps:

[0017] S1: The drone, carrying the data acquisition device, flies over the area of ​​the target level ecological corridor according to the ecological corridor level classification, so that the data acquisition device can collect remote sensing images of the area.

[0018] S2: During the acquisition of remote sensing images, the drive motor periodically drives the mounting arm to rotate, causing the wiping block to wipe the lens at the acquisition end. After wiping is completed, the unloading part removes the wiping block from the mounting arm, and the replacement part discharges the spare wiping block inside the moving frame and installs it on the mounting arm.

[0019] Compared with the prior art, the beneficial effects of the present invention are: by replacing components and unloading parts, the used wiping block or spare wiping block is replaced to ensure that there is no moisture on the wiping block or spare wiping block for wiping the acquisition end lens, thus ensuring the wiping effect of the acquisition end, making the clarity of remote sensing image acquisition higher, and providing accurate data for ecological corridor planning and monitoring.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1 The remote sensing image acquisition device based on the classification of ecological corridors includes: a drone 1 and an acquisition end 2 (the acquisition end 2 refers to a camera used to acquire remote sensing images; this device is an existing device and will not be described in detail here). The acquisition end 2 can be detachably installed on the bottom of the drone 1 (e.g., by fixing it with bolts, the acquisition end 2 can be connected to the drone 1 and can be removed).

[0031] Please see Figure 1 and Figure 3 The drone 1 is equipped with a drive motor 5, and a mounting arm 6 is provided on the output end of the drive motor 5. A rubbing block 10 is installed on the top of the mounting arm 6.

[0032] Please see Figure 3 and Figure 4 The drone 1 is equipped with a replacement component 8;

[0033] The replacement component 8 includes a mounting part 81 (the mounting part 81 is a block or plate), the mounting part 81 is provided with a movable frame 82, and a spare cleaning block 7 is placed inside the movable frame 82 (according to...). Figure 4 As shown, there are four spare wiping blocks 7; the number of spare wiping blocks 7 can also be other, depending on the flight time required by the UAV 1 during actual use. The moving frame 82 is equipped with a replacement part, which is used to discharge the spare wiping blocks 7 inside the moving frame 82.

[0034] The remote sensing image acquisition method based on the classification of ecological corridors (the following is the specific process of using a remote sensing image acquisition device to acquire remote sensing images in ecological corridors, taking the Taihu Lake Basin ecological corridor in Zhejiang Province as an example), is as follows:

[0035] First, bring the remote sensing image acquisition device to the area where data information needs to be collected. The drone 1, carrying the acquisition end 2, flies over the area of ​​the target level ecological corridor according to the ecological corridor level classification, and the acquisition end 2 collects remote sensing images of the area (communication equipment can be installed on the drone 1 to transmit the collected remote sensing images to the ground user terminal in real time, the user terminal refers to devices such as computers and mobile phones).

[0036] Second, during the acquisition of remote sensing images, the drive motor 5 periodically drives the mounting arm 6 to rotate (the periodicity is a time preset by the staff, such as one minute, two minutes, etc., set according to actual needs), so that the wiping block 10 wipes the lens of the acquisition end 2. After wiping is completed, the unloading part 9 removes the wiping block 10 from the mounting arm 6, and the replacement part discharges the spare wiping block 7 inside the moving frame 82 and installs it on the mounting arm 6 so that the spare wiping block 7 can be used for the next wiping.

[0037] It should be noted that by replacing the wiping block 10 or the spare wiping block 7 each time it is used, the wiping block 10 or the spare wiping block 7 used to wipe the lens of the acquisition end 2 is kept dry, thus avoiding the situation where water is left on the lens of the acquisition end 2 during the wiping process.

[0038] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5 The mounting component 81 is provided with a first telescopic component 83 (electric telescopic rod). The moving end of the first telescopic component 83 is connected to the moving frame 82 and is used to drive the moving frame 82 to rise and fall. There are several spare cleaning blocks 7. The spare cleaning blocks 7 are placed in the inner cavity of the moving frame 82 from top to bottom. The inner side wall of the moving frame 82 is provided with a mounting groove. The replacement component includes a second telescopic component 84 (electric telescopic rod) provided in the mounting groove. The moving end of the second telescopic component 84 is provided with a limiting block. The side walls of the spare cleaning blocks 7 are all provided with limiting grooves 85. The limiting block is inserted into the limiting groove 85 of the lower spare cleaning block 7 to fix the lowermost spare cleaning block 7, so that the spare cleaning blocks 7 stay in the inner cavity of the moving frame 82 (the moving frame 82 is a U-shaped kit, equivalent to a square tube, which isolates the spare cleaning blocks 7 inside the moving frame 82 from the outside world and protects them).

[0039] Please see Figure 6 and Figure 7The cleaning block 10 has the same structure as the spare cleaning block 7; the spare cleaning block 7 includes a base 71 and a cleaning block 72 set on the base 71 (the base 71 is a rigid material, such as plastic, and a counterweight is installed on the base 71 to increase the weight of the spare cleaning block 7 and the cleaning block 10; the cleaning block 72 is made of sponge material). An electromagnet 75 is provided at the bottom of the base 71, and the mounting arm 6 can be magnetically attracted (the mounting arm 6 is made of metal, such as iron). A storage groove is provided at the bottom of the base 71, and a moving block 73 (which can move up and down) slides within the storage groove. An elastic element (spring) is installed between the storage groove and the moving block 73. A first touch switch 74 is installed in the inner cavity of the storage groove, and the first touch switch 74 is located above the moving block 73. The first touch switch 74 is connected in series with the power supply and electromagnet 75 via wires (the power supply refers to the battery, which is installed on the first touch switch 74). The second touch switch 79 is provided on the side wall of the base 71. The second touch switch 79 is connected in series with the circuit composed of the first touch switch 74, the power supply, and the electromagnet 75. (When the second touch switch 79 is pressed, the circuit in the area where the second touch switch 79 is located is open, and vice versa; when the first touch switch 74 is pressed, the circuit in the area where the first touch switch 74 is located is closed, and vice versa). The unloading part 9 is a baffle. The baffle is located on the moving path of the rubbing block 10. The height of the bottom of the baffle is higher than the height of the top of the mounting arm 6, so that the baffle will not contact the mounting arm 6 and the rotation of the mounting arm 6 is not affected by the baffle.

[0040] It should be noted that after the drive motor 5 drives the mounting arm 6 to rotate, causing the wiping block 10 to wipe the lens of the acquisition end 2, the drive motor 5 continues to rotate with the mounting arm 6, causing the side wall of the wiping block 10 to contact the unloading component 9. At this time, the unloading component 9 will press the second touch switch 79, de-energizing the electromagnet 75 on the wiping block 10 and releasing the attraction between the wiping block 10 and the mounting arm 6. The drive motor 5 continues to rotate with the mounting arm 6, and the mounting arm 6 passes over the unloading component 9, while the wiping block 10 is blocked by the unloading component 9, separating the wiping block 10 from the mounting arm 6. When the mounting arm 6 rotates to below the moving frame 82, the drive motor 5 stops working, and at the same time, the first telescopic component 83 drives the moving frame 82 to move down to the predetermined position (at this time, the distance between the bottom of the moving frame 82 and the mounting arm 6 is the height of a spare wiping block 7). Then the second telescopic component 83... The retractable component 84, carrying the limiting block, moves out of the limiting groove 85, releasing the restriction on the spare cleaning block 7. Under the action of gravity, all the spare cleaning blocks 7 will descend, and the lowest spare cleaning block 7 will contact the mounting arm 6 (i.e., the base 71 of this spare cleaning block 7 contacts the mounting arm 6). At this time, the moving block 73 will be pressed upward by the mounting arm 6, causing it to press the first touch switch 74, turning on the power to the electromagnet 75, so that it generates magnetic force and attracts the spare cleaning block 7 onto the mounting arm 6. At the same time, the second telescopic component 84, carrying the limiting block, resets and inserts into the limiting groove 85 of the lowest spare cleaning block 7 inside the moving frame 82 to fix it. Then, the first telescopic component 83 moves upward and resets the moving frame 82, completing the replacement of the cleaning block 10. After the spare cleaning block 7 is used later, the above steps are followed to replace the spare cleaning block 7 again.

[0041] It should also be noted that during the above replacement process, the central processing unit (computer) controls the work in a unified manner, ensuring the automation of the replacement process; and the automation control is an existing technology (controlled by pre-set programs), which will not be described in detail here.

[0042] In this embodiment, as a further optimization, please refer to... Figure 6The base 71 has a mounting slot at its bottom, and the electromagnet 75 is slidably disposed in the inner cavity of the mounting slot (the electromagnet 75 can move up and down in the inner cavity of the mounting slot). A spring is provided between the electromagnet 75 and the mounting slot. A magnetic block 76 is provided in the inner cavity of the mounting slot, and the magnetic block 76 is located above the electromagnet 75. The magnetic poles of the magnetic block 76 and the electromagnet 75 are the same on the side that are close to each other (the two will generate a repulsive force when they are close to each other; the electromagnet 75 generates magnetic force on both the top and bottom sides). The mounting arm 6 has a slot at its top. When the first touch switch 74 controls the electromagnet 75 to be energized and generate magnetic force, the electromagnet 75 and the magnetic block 76... The two forces will repel each other, causing the electromagnet 75 to move down and insert into the slot, preventing the spare wiping block 7 and wiping block 10 from moving horizontally when installed on the mounting arm 6. This increases the stability of the spare wiping block 7 and wiping block 10 installation and ensures that the spare wiping block 7 and wiping block 10 will not move during the wiping of the collection end 2, ensuring that the wiping is clean. After the electromagnet 75 is de-energized, the magnetic force on the electromagnet 75 disappears, and the magnetic force between the electromagnet 75 and the magnetic block 76 disappears. Under the action of the spring, the electromagnet 75 moves up to reset and moves out of the slot, ensuring that the baffle (feeding part 9) can separate the wiping block 10 or the spare wiping block 7 from the mounting arm 6.

[0043] In this embodiment, as a further optimization, please refer to... Figure 6 and Figure 7 A slot 77 is provided on the side wall of the base 71, and the second touch switch 79 is slidably disposed in the slot 77 (the second touch switch 79 can move left and right in the slot 77). An elastic element 78 (spring) is provided between the slot 77 and the second touch switch 79. The slot 77 is used to store the second touch switch 79. When the spare cleaning block 7 is inside the moving frame 82, the second touch switch 79 is restrained by the moving frame 82 and will be in the inner cavity of the slot 77. At this time, the second touch switch 79 is pressed, that is, the electromagnet 75 cannot be energized. When the spare cleaning block 7 is discharged from the moving frame 82, the second touch switch 79 is unrestrained and moves to the outside of the slot 77 under the action of the elastic element 78.

[0044] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 2 and Figure 3The bottom of the drone 1 is equipped with a mounting box 3. The drive motor 5, the mounting component 81 and the unloading component 9 are all set in the inner cavity of the mounting box 3. An opening 4 is opened on the side wall of the mounting box 3. When the drive motor 5 drives the mounting arm 6 to rotate, the mounting arm 6 and the wiping block 10 or spare wiping block 7 can enter and exit the mounting box 3 through the opening 4. The mounting box 3 can be used to store the drive motor 5, the mounting component 81 and the unloading component 9, which can protect the wiping block 10 and the spare wiping block 7. When the baffle (unloading component 9) scrapes the used wiping block 10 or spare wiping block 7 off the mounting arm 6, the wiping block 10 and the spare wiping block 7 fall to the bottom of the inner cavity of the mounting box 3 and are collected by the mounting box 3.

[0045] It should be noted that the mounting box 3 can be detachably mounted on the drone 1 (e.g., by bolting the two together), so that the mounting box 3 can be removed from the drone 1, and then the drive motor 5, mounting component 81 and unloading component 9 can be removed. The mounting box 3 is composed of a box body and a box panel, which are detachably connected. When the box panel and the box body are separated, the interior of the mounting box 3 can be opened for inspection or replacement of the components inside the mounting box 3.

[0046] In this embodiment, as a further optimization, please refer to... Figure 3 The mounting arm 6 includes a support arm 61 and a movable arm 62 (both support arms 61 and movable arms 62 can be magnetically attracted, such as by iron). The support arm 61 is mounted on the output shaft of the drive motor 5. The support arm 61 is equipped with a drive component (electric telescopic rod). The moving end of the drive component is connected to the movable arm 62. The wiping block 10 is mounted on the movable arm 62. When the drive component is working, it can move the movable arm 62 to move it closer to or further away from the support arm 61, change the length of the mounting arm 6, ensure that it can enter the interior of the mounting box 3, and also ensure that it can wipe the lens of the acquisition end 2 with the wiping block 10 or the spare wiping block 7.

[0047] 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.
