Description

Technical Field

[0001] This invention relates to the field of vegetation monitoring technology, specifically to an Internet of Things (IoT) monitoring device for garden vegetation. Background Technology

[0002] Gardens refer to beautiful natural environments and recreational areas created within a specific region through engineering technology and artistic means, such as modifying the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. Scientific and precise monitoring and management of garden vegetation is a crucial link in ensuring the ecological function and landscape quality of urban green spaces. Multispectral imaging technology provides an effective technical means for this purpose. Based on this technology, an Internet of Things (IoT) monitoring device for garden vegetation collects the reflectance spectrum of vegetation in the visible to near-infrared wavelength range to monitor, analyze, and evaluate related plants and their growth environment in order to obtain the growth status and key physiological indicators of the vegetation.

[0003] While existing IoT monitoring devices can perform routine multispectral imaging monitoring of garden vegetation, in actual use, due to their relatively fixed installation height, rainwater interferes with the normal acquisition of spectral signals during rainy weather, resulting in unclear detection, reduced image quality, and difficulty in obtaining effective monitoring data. Furthermore, their fixed height makes it difficult to adaptively adjust the monitoring height according to weather conditions. This hinders proactively avoiding rain interference during rainy days and makes it difficult to quickly restore the device to optimal operating conditions after the rain stops, thus affecting the accuracy of data acquisition and the overall effectiveness of the monitoring device.

[0022] The specific implementation process is as follows: Rainwater falls on the water collection frame 8. When the rainfall increases and the water accumulation rate of the water collection frame 8 is faster than the drainage rate of the open sections on both sides, the water level inside the water collection frame 8 continuously rises, increasing the overall weight. This causes the support leg 7, which is fixed in the middle of the lower end of the water collection frame 8, to move downwards synchronously. The descending support leg 7 drives the turntable 11, which is rotatably connected to the lower end, to move downwards stably under the constraint of the inner wall of the slide groove 4 opened on the upper side of the rod body 1. The guide rod 12, which is fixed on one side of the turntable 11, is slidably connected to the spiral groove 5 opened on the side wall of the slide groove 4. As the guide rod 12 moves downwards with the turntable 11, the turntable 11 rotates while moving downwards due to the guiding effect of the spiral groove 5. The downward-moving and rotating turntable 11 compresses the support frame 13 that is in contact with the lower end, causing the support frame 13 to compress the spring 14, providing space for the movement of the support frame 13. At the same time, the limiting frame 15, which is fixed to the middle of the lower end of the turntable 11, moves down and rotates synchronously under the limiting of the inner wall of the slide groove 4, which drives the slider 16, which is slidably connected to its inner wall, to rotate under the support of the connecting rod 17, and then drives the connecting rod 17 and the threaded rod 18 fixed at the lower end to rotate synchronously. The outer surface of the rotating threaded rod 18 is threadedly connected to the inner wall of the middle part of the threaded frame 19, allowing the threaded frame 19 to slide downwards under the constraint of the inner wall of the through groove 6. The middle part of the threaded frame 19 is fixed to the middle part of the sealing frame 20, which is slidably connected to the surface of the rod body 1 to shield the through groove 6 and prevent water from entering the through groove 6. At the same time, the moving threaded frame 19 drives the support 21 fixed at the other end and the multispectral camera 2 fixed at the other end to move downwards synchronously. The multispectral camera 2 is electrically connected to the solar panel 3, which supplies it with power. During the downward movement, the unblocking frame 10 fixed on both sides of the rod body 1 slides into the opening of the water collection frame 8. The comb-shaped unblocking frame 10 lifts and unblocks the impurities blocking the outlet of the water collection frame 8. At the same time, the unblocking frame 10 lifts the lifting frame 9 until the lifting frame 9 reaches the top, causing larger impurities falling on the lifting frame 9 to fall off the water collection frame 8. After the rain stops, the previously compressed spring 14 drives the threaded rod 18 to reverse, and all components reset, achieving an adaptive height adjustment effect. The monitoring height can be adaptively adjusted according to the weather conditions. When it rains, the water collection rack 8 uses the weight of the rainwater to automatically trigger the lifting mechanism, driving the multispectral camera to actively descend. This shortens the optical path and reduces the interference of rainwater on the lens and spectral signal, avoiding the collection of invalid or distorted monitoring data. After the rain stops, the spring 14 reset mechanism drives all components to automatically rise, allowing the camera to return to the optimal monitoring height in a timely manner. It can be put back into normal working condition without manual intervention, thereby improving the data acquisition accuracy and overall use effect of the monitoring device.

[0023] Example 2 Rainwater can adhere to the surface of camera lenses, causing blurred images, distorted spectral signals, and reduced effectiveness of monitoring data. Therefore, it is necessary to install a shielding structure to protect the camera from rain, preventing rainwater from directly contacting the lens, thereby improving the environmental adaptability and monitoring reliability of the monitoring device.

[0024] Please see Figures 1-9 As shown, an automatic masking function has been added based on Embodiment 1; Please refer to it again. Figures 1-9 As shown, a stabilizing groove 22 is provided in the middle of the support 21. A stabilizing block 23 is slidably connected to the inner wall of the stabilizing groove 22. A fixing rod 24 is fixed to one end of the stabilizing block 23. A connecting frame 25 is rotatably connected to the outer surface of the fixing rod 24. A connecting rod 26 is rotatably connected to the other end of the connecting frame 25. A shielding frame 27 is fixed to the upper end of the support 21. The stabilizing groove 22 is located on the side of the support 21 near the rod 1. The cross section of the stabilizing groove 22 is cross-shaped. The outer surface of the stabilizing block 23 is slidably connected to the inner wall of the stabilizing groove 22. The vertical section of the stabilizing block 23 is cross-shaped. The upper end of the stabilizing block 23 is fixed to one corner of the shielding frame 27. The shielding frame 27 is located above the multispectral camera 2. The vertical section of the shielding frame 27 is Z-shaped. The lower end of the stabilizing block 23 is fixed to one end of the fixing rod 24. The outer surface of the fixing rod 24 is rotatably connected to the upper end of the connecting frame 25. The lower end of the connecting frame 25 is rotatably connected to the outer surface of the connecting rod 26. One end of the connecting rod 26 is fixed to one side of the rod 1.

[0025] The specific implementation process is as follows: Rainwater falls on the water collection frame 8. When the rainfall increases and the water accumulation rate of the water collection frame 8 is faster than the drainage rate of the hollowed-out positions on both sides, the water level inside the water collection frame 8 continuously rises, increasing the overall weight. This causes the support leg 7, which is fixed in the middle of the lower end of the water collection frame 8, to move downwards synchronously. The moving support leg 7, through the turntable 11, the limiting frame 15, the slider 16, the connecting rod 17, and the threaded rod 18, drives the threaded frame 19 and the support 21 to move downwards synchronously. A stabilizing groove 22 is provided in the middle of the support 21. A stabilizing block 23 is slidably connected to the inner wall of the stabilizing groove 22. A fixing rod 24 is fixed to one end of the stabilizing block 23. The outer surface of the fixing rod 24 is rotatably connected to the upper end of the connecting frame 25, and the lower end of the connecting frame 25 is rotatably connected to the outer surface of the connecting rod 26. One end of the connecting rod 26 is fixed to one side of the rod body 1. When the support 21 moves down, the stabilizing block 23 moves under the support of the connecting frame 25, and drives the upper fixed shielding frame 27 to move synchronously. Finally, the shielding frame 27 moves above the multispectral camera 2, realizing the automatic shielding effect of the camera, forming a physical barrier around the lens, effectively blocking rainwater from directly impacting the lens surface, avoiding light path obstruction and signal attenuation caused by raindrops, ensuring that precision optical components are protected from rainwater corrosion, thereby improving the environmental adaptability and monitoring reliability of the monitoring device.

[0026] Example 3 Cameras are exposed to outdoor environments for extended periods, and rainwater can easily cause impurities to adhere to the lens surface, affecting image quality and the accuracy of spectral data. Therefore, it is necessary to install an automatic cleaning device to clean the lens during rain, thereby improving the long-term operational stability of the monitoring device.

[0027] Please see Figures 1-9 As shown, an automatic cleaning function has been added based on Embodiment 1; Please refer to it again. Figures 1-9 As shown, a rotating frame 28 is rotatably connected to the inner wall of one side of the shielding frame 27. A gear 29 is fixed to one side of the rotating frame 28. The gear 29 meshes with a rack 30. A cleaning brush 31 is fixed to the lower end of the rotating frame 28. The upper outer surface of the rotating frame 28 is rotatably connected to the inner wall of one side of the shielding frame 27. The vertical section of the rotating frame 28 is T-shaped. The middle part of the gear 29 is fixed to the upper side of the rotating frame 28. The gear 29 meshes with the rack 30. One side of the rack 30 is fixed to one side of the support 21. The upper end of the cleaning brush 31 is fixed to the lower end of the rotating frame 28. The bristles of the cleaning brush 31 are in contact with the outer surface of the multispectral camera 2.

[0028] The specific implementation process is as follows: Rainwater falls on the water collection frame 8. When the rainfall increases and the water collection speed of the water collection frame 8 is faster than the drainage speed of the hollowed-out positions on both sides, the water level inside the water collection frame 8 continuously rises, increasing the overall weight. This causes the support leg 7, which is fixed in the middle of the lower end of the water collection frame 8, to move downwards synchronously. The downward-moving support leg 7 drives the threaded frame 19 and the support 21 to move downwards synchronously via the turntable 11, the limiting frame 15, the slider 16, the connecting rod 17, and the threaded rod 18. The downward-moving support 21 drives the shielding frame 27 to move via the stabilizing groove 22, the stabilizing block 23, the fixing rod 24, the connecting frame 25, and the connecting rod 26. The moving shielding frame 27 drives the rotating frame 28, which is rotatably connected to the inner wall on the other side, to move synchronously. The upper side of the rotating frame 28 is fixed to the middle of the gear 29. The gear 29 meshes with the rack 30, which is fixed to one side of the support 21, so that when the shielding frame 27 moves, the rotating frame 28 rotates simultaneously. The moving and rotating frame 28 drives the cleaning brush 31 fixed at the lower end to move and rotate synchronously. When the cleaning brush 31 passes the multispectral camera 2, it cleans the lens surface, removing rainwater, dust and impurities attached to the lens, realizing the automatic cleaning effect of the lens when it rains. This avoids the long-term adhesion of pollutants affecting the imaging quality and the accuracy of spectral data. The physical cleaning of the lens surface by sweeping can effectively remove the stains and attachments left after the rainwater evaporates, preventing them from accumulating on the lens surface and forming a blocking layer. This avoids the scattering or attenuation of incident light due to lens contamination, ensuring that the multispectral imaging unit can always stably receive the spectral signals reflected by the vegetation, thereby improving the long-term operational stability of the monitoring device.
