Description

Technical Field

[0001] The present invention relates to the field of seedling monitoring, and in particular to a seedling monitoring device for analyzing forest regeneration capacity. Background Art

[0002] Forest regeneration capacity is a core indicator for assessing the health, resilience and future productivity of forest ecosystems. Forest regeneration is mainly achieved through natural regeneration and artificial regeneration. Artificial regeneration is more stable and controllable, and the survival rate of seedlings is higher. The survival, growth status and spatial distribution of seedlings are the most direct and sensitive factors reflecting the natural regeneration potential of forests. Accurate, efficient and long-term monitoring of forest seedling dynamics is of vital importance to the sustainable development of forests, restoration of degraded ecosystems, biodiversity protection and response to climate change.

[0003] Existing seedling monitoring equipment used for forest regeneration capacity analysis is usually carried out by investigators who carry the equipment to the target monitoring site of artificially regenerated seedlings. After installing a fixed bracket, a high-definition camera is used to take multiple images of the seedlings over a long period of time.

[0040] An auxiliary support 14 is fixedly mounted on the top of the other two pillars 1. An auxiliary rod 15 is rotatably mounted between the two ends of the auxiliary support 14. An auxiliary block 16 is slidably connected to the surface of the auxiliary rod 15.

[0041] A longitudinal moving mechanism 4, the longitudinal moving mechanism 4 being fixedly mounted on the top of the transverse moving block 303 and the auxiliary block 16;

[0042] A vertical moving mechanism 5, wherein the vertical moving mechanism 5 is fixedly installed on one side of the longitudinal moving mechanism 4;

[0043] A high-definition camera 6, which is fixedly mounted on the bottom of the vertical moving mechanism 5;

[0044] The Internet of Things controller 2 is used to connect and manage sensors, actuators and communication modules in the device.

[0045] The longitudinal moving mechanism 4 includes a longitudinal support 401, which is fixedly installed on the top of the lateral moving block 303 and the auxiliary block 16. A longitudinal screw 402 is rotatably installed between the two ends of the longitudinal support 401. The surface of the longitudinal screw 402 is threadedly connected to the longitudinal moving block 403. One end of the longitudinal screw 402 passes through the longitudinal support 401 and extends to the outside. The end of the longitudinal screw 402 located outside the longitudinal support 401 is fixedly connected to a longitudinal motor 404.

[0046] The vertical moving mechanism 5 includes a vertical support 501, which is fixedly installed on one side of the longitudinal moving block 403. A vertical screw 502 is rotatably installed between the two ends of the vertical support 501. The surface of the vertical screw 502 is threadedly connected to the vertical moving block 503. One end of the vertical screw 502 passes through the vertical support 501 and extends to the outside. The end of the vertical screw 502 located outside the vertical support 501 is fixedly connected to a vertical motor 504.

[0047] The high-definition camera 6 is fixedly installed at the bottom of the vertically movable block 503 , and the shooting end of the high-definition camera 6 is vertically downward.

[0048] During actual use, the high-definition camera 6 can be selected as EZVIZ C3W Pro; the Internet of Things controller 2 is a control system used to integrate the entire process of data acquisition, processing, transmission, control and system management and has networking functions; one side of the vertical moving block 503 is shaped like a T-shaped plate; the auxiliary support 14 and the horizontal support 301 are the same length.

[0049] The working principle of the seedling monitoring device for forest regeneration capacity analysis provided by the present invention is as follows:

[0050] First, the device is installed by means of support 1 at the site where the seedlings are to be artificially regenerated in the forest.

[0051] Then, a large area of seedlings is photographed by the high-definition camera 6, and the image recognition algorithm is used to analyze the number of leaves, branch structure, crown area, etc. The collected data is uploaded to the cloud by the Internet of Things controller 2 for storage. When photographing and collecting seedlings farther away in an area, the horizontal motor 13 is started to drive the horizontal screw 302 to rotate. The horizontal screw 302 is threadedly connected to the horizontal moving block 303, so that the horizontal moving block 303 moves horizontally, and the auxiliary block 16 and the auxiliary rod 15 cooperate to drive the longitudinal support 401 to move horizontally. The longitudinal motor 404 is started to drive the longitudinal screw 402 to rotate. The longitudinal screw 402 is threadedly connected to the longitudinal moving block 403 to drive the vertical support 501 to move vertically. At this time, the high-definition camera 6 can shoot at any point on the plane in the area where the seedlings are artificially renewed, avoiding errors caused by shooting at a long distance.

[0052] Then, when the seedlings have just broken through the soil and their growth is low, the vertical motor 504 is started to drive the vertical screw 502 to rotate. The vertical screw 502 is threadedly connected to the vertical moving block 503 to drive the vertical moving block 503 to move in the vertical direction. The vertical moving block 503 drives the high-definition camera 6 to rise and fall in the vertical direction, thereby also driving the high-definition camera 6 to shoot any point in the three-dimensional space. As the seedlings grow, the height of the high-definition camera 6 can be gradually increased, and the seedling image can be captured more clearly with its own zoom.

[0053] Finally, after the seedlings have grown for a period of time, the monitoring equipment can be disassembled and moved to other locations that need monitoring.

[0054] Compared with related technologies, the seedling monitoring device for forest regeneration capacity analysis provided by the present invention has the following beneficial effects:

[0055] By setting up a three-axis linkage of the horizontal moving mechanism 3, the longitudinal moving mechanism 4, and the vertical moving mechanism 5, the high-definition camera 6 can be used to shoot at any point in the three-dimensional space to eliminate errors, without the need for manual long-term round-trip planting area, so as to facilitate the acquisition of all-round and multi-angle seedling morphological images. The high-definition camera 6 works in coordination with its own optical zoom function when it is vertically raised and lowered with the vertical moving block 503. It can synchronously raise the camera position and shorten the focal length after the seedling grows taller, always maintaining clear imaging quality of leaf texture and branch details, and accurately adapting to the monitoring needs of seedlings at different stages from breaking through the soil to growing taller.

[0056] Second embodiment

[0057] Please refer to Figure 6-Figure 8Based on the seedling monitoring device for forest regeneration capacity analysis provided in the first embodiment of this application, the second embodiment of this application provides another seedling monitoring device for forest regeneration capacity analysis. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0058] Specifically, the difference of the seedling monitoring equipment for forest regeneration capacity analysis provided in the second embodiment of the present application is that a probe mechanism 7 is fixedly installed on one side of the vertical support 501, and the probe mechanism 7 includes a three-stage hydraulic cylinder 701, and the three-stage hydraulic cylinder 701 is fixedly installed on one side of the vertical support 501 through a support plate, and a probe 702 is fixedly installed at the bottom end of the three-stage hydraulic cylinder 701.

[0059] It also includes a water supply mechanism 8, which includes a water tank 801 placed on the ground, a submersible pump 802 fixedly installed at the bottom of the inner wall of the water tank 801, and a water supply pipe 803 fixedly connected to the output end of the submersible pump 802. The water supply pipe 803 passes through one side of the water tank 801 and extends to the outside, and the end of the water supply pipe 803 is connected to a hose 804. Two discs 806 are rotatably installed on one side of the water tank 801 through two rotating frames 807, and a winding column 805 is fixedly installed between the two discs 806. The hose 804 is arranged on the surface of the winding column 805, and a motor 808 is fixedly installed on one side of one of the discs 806. The motor 808 is fixedly installed on one side of the water tank 801 through a bracket, and the end of the hose 804 is connected to a ring-shaped water outlet pipe 809.

[0060] The bottom of the annular water outlet pipe 809 is opened, and the annular water outlet pipe 809 is adapted to be installed with the three-stage hydraulic cylinder 701 .

[0061] During actual use, the probe 702 is integrated with a pH detection sensor and a humidity and temperature sensor; a water inlet is provided at the top of the water tank 801; a hole is provided at the bottom of the annular water outlet pipe 809 as a water outlet; the hose 804 on the winding column 805 is in the initial state, and after resetting, it is in other states without affecting the next release of the hose 804.

[0062] The working principle of the seedling monitoring device for forest regeneration capacity analysis provided in this embodiment is as follows:

[0063] First, water is replenished inside the water tank 801 through the water inlet. During the shooting process, soil testing is performed to determine the soil conditions of the seedlings at different growth stages. The three-stage hydraulic cylinder 701 drives the probe 702 downward to enter the soil to analyze the pH value, humidity, temperature, etc. The probe 702 enters the soil and is on the side of the seedling without touching the seedling.

[0064] Then, after the probe 702 completes the detection and uploads the data, the three-stage hydraulic cylinder 701 drives the reset and starts the submersible pump 802 to pump water from the water supply pipe 803 to the hose 804. Finally, water is discharged downward from the water outlet hole at the bottom of the annular outlet pipe 809 to clean the sensor on the probe 702 to avoid errors in the next detection. At the same time, the cleaning water flow is reused as irrigation water to replenish water for the seedlings.

[0065] Finally, the hose 804 is wound around the surface of the winding column 805. When the three-stage hydraulic cylinder 701 follows the vertical support 501 to different points for detection, the winding column 805 releases the hose 804 as the disc 806 rotates and moves with it. When resetting, the motor 808 is started to drive the disc 806 to rotate. The rotation of the disc 806 drives the winding column 805 to rotate and cooperate to wind the hose 804 back onto the surface of the winding column 805.

[0066] Compared with related technologies, the seedling monitoring device for forest regeneration capacity analysis provided in this embodiment has the following beneficial effects:

[0067] By setting up the probe 702, multiple parameters of the seedling soil at different stages can be detected during shooting, which is beneficial for investigators to analyze the impact of environmental factors on seedling growth. By setting up the annular water outlet pipe 809, the sensor on the probe 702 can be cleaned during the downward water discharge process to avoid cross-data influence. The cleaning water flow can be reused as irrigation water to replenish water for the seedlings.

[0068] Third embodiment

[0069] Please refer to Figure 6 、 Figure 9 and Figure 10 Based on the seedling monitoring device for analyzing forest regeneration capacity provided in the first embodiment of this application, the third embodiment of this application provides another seedling monitoring device for analyzing forest regeneration capacity. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0070] Specifically, the difference of the seedling monitoring equipment for forest regeneration capacity analysis provided in the third embodiment of the present application is that a switching mechanism 9 is fixedly installed on one side of the high-definition camera 6, and the switching mechanism 9 includes a fixed block 901, and the fixed block 901 is fixedly installed on one side of the high-definition camera 6. A rotating shaft 902 is rotatably installed inside the fixed block 901, and a filter 903 is fixedly installed on the bottom end of the rotating shaft 902. A ratchet 904 is fixedly installed on the top of the rotating shaft 902, and a spring base 905 is fixedly installed on the top of the high-definition camera 6. The spring base 905 is fixedly connected to a drive plate 907 through a spring 906, and a pawl 908 is fixedly installed on one side of the drive plate 907, and the pawl 908 engages with the ratchet 904.

[0071] The two ends of the filter 903 are two types of filters, namely a red filter end and a green filter end, which are used to suppress ambient light interference.

[0072] Two support frames 10 are fixedly installed between the two left pillars 1. Three bending plates 11 are fixedly installed on the two support frames 10. The three bending plates 11 are each provided with three bending parts and a brush plate 12 is fixedly installed on the top of the three bending parts.

[0073] In actual use, the brush plate 12 uses antistatic carbon fiber bristles; the brush plate 12 is detachable and replaceable.

[0074] The working principle of the seedling monitoring device for forest regeneration capacity analysis provided in this embodiment is as follows:

[0075] First, when photographing the seedlings in the entire area, filter 903 was set to avoid interference from ambient light in the forest sunlight. The red light reflectivity of the red filter end of filter 903 directly reflects the photosynthetic potential of the leaves, and the green filter end of filter 903 can clearly depict the outline of the leaf edge.

[0076] Then, after photographing the seedlings with the red end of the filter 903, the longitudinal moving block 403 drives the high-definition camera 6 to move to the left to the position of the bending plate 11. After the movement is completed, the driving plate 907 is in contact with one side of the bending plate 11, and the driving plate 907 squeezes the spring 906 to contract, and the pawl 908 also moves to the right. The red end of the filter 903 moves to the top of the brush plate 12 for cleaning. When continuing to move to the right to shoot, the driving plate 907 disengages from the bending plate 11 and the spring 906 drives the driving plate 907 to reset. At this time, the pawl 908 engages the ratchet 904 to push it to rotate 180°, thereby switching the filter 903 to the green end.

[0077] Then, the three bending plates 11 can cooperate with the high-definition camera 6 to switch the filter 903 at different horizontal points. The brush plates 12 are fixedly installed on the top of the three bending parts. The filters 903 can be switched at different vertical heights while cleaning the used filters 903 to avoid the attached dust and impurities affecting the taken pictures.

[0078] Finally, the pictures taken with the two filters 903 are analyzed by an algorithm to form an image that avoids interference from ambient light.

[0079] Compared with related technologies, the seedling monitoring device for forest regeneration capacity analysis provided in this embodiment has the following beneficial effects:

[0080] After the spring 906 is compressed by the driving plate 907 and detached from the bending plate 11, the pawl 908 pushes the ratchet 904 to automatically switch the two ends of the filter 903, thereby separating specific spectral information and enhancing the identifiability of the physiological and structural characteristics of vegetation. The brush plate 12 can remove impurities such as dust and pollen to avoid reduced imaging accuracy. By setting three bending plates 11, the filter 903 can be switched at different horizontal points. The bending part of the bending plate 11 itself can switch the filter 903 at different vertical heights and clean the used filter 903 at the same time, meeting the needs of different growth stages when monitoring seedlings.
