Description

Technical Field

[0001] The present invention relates to the technical field of ecological carrying capacity assessment, and in particular to an assessment system and method for the ecological carrying capacity of mountain vegetation based on image analysis. Background Art

[0002] As human beings continue to develop and progress, we are increasingly aware of the importance of protecting the environment. As the cornerstone of environmental protection, ecological carrying capacity has also attracted more and more attention. In order to promote sustainable development and ensure that our actions do not cause irreversible damage to the environment, it is necessary to evaluate ecological carrying capacity.

[0003] At present, when evaluating the ecological carrying capacity of mountain vegetation, the image information of mountain vegetation is usually collected by the collection equipment in the evaluation system, and then the evaluation is carried out after analysis based on the collected image information. When the collection equipment in the evaluation system is used, it needs to be installed in the area to be monitored. Generally, the collection equipment is inserted into the soil. Although this method can fix the collection equipment in the area to be monitored, since the image information of mountain vegetation is collected, the collection equipment is installed in the wild. Strong winds are inevitable in the wild, and the existing collection equipment usually does not have a windproof structure. When encountering strong winds, the collection equipment will collapse, which will cause the collection equipment to be damaged and unable to collect image information of mountain vegetation, affecting the evaluation of the ecological carrying capacity of mountain vegetation. To this end, we propose an evaluation system and method for the ecological carrying capacity of mountain vegetation based on image analysis. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see attached Figure 1 -Attached Figure 4

[0035] An evaluation system for the ecological carrying capacity of mountain vegetation based on image analysis, comprising a collection unit for collecting image information of mountain vegetation in a monitored area, a transmission unit for transmitting the image information of mountain vegetation in a monitored area, and an evaluation unit for receiving the image information of mountain vegetation in a monitored area and evaluating the ecological carrying capacity of mountain vegetation;

[0036] The image information of mountain vegetation in the monitored area is collected by the collection unit, and the information such as the growth status of the mountain vegetation in the monitored area can be obtained from the image information of the mountain vegetation. The evaluation unit is, for example, a computer or other processing equipment. The evaluation unit may also include a storage module, a comparison module and an evaluation module. The image information of mountain vegetation in the monitored area collected by the collection unit is stored by the storage module. The image information of mountain vegetation in the monitored area in different time periods or after different events in the storage module is compared by the comparison module to obtain a comparison result. The evaluation module can evaluate the ecological carrying capacity of the mountain vegetation in the monitored area according to the comparison result, and the evaluation level is, for example, excellent, medium and good;

[0037] The above-mentioned different events are, for example, comparing the image information of the growth state of mountain vegetation in the monitored area after being disturbed by human activities with the image information of the growth state of mountain vegetation in the monitored area without being disturbed by human activities;

[0038] The transmission unit is, for example, a wireless communication device.

[0039] The acquisition unit includes: a bottom plate 1, a top plate 2, a rod 3 connecting the bottom plate 1 and the top plate 2, a fixing member provided at the bottom of the bottom plate 1 for inserting and installing in the ground soil, a windproof member rotatably provided between the bottom plate 1 and the top plate 2, and an image acquisition device 19 provided on the top plate 2 through a support frame 27, the image acquisition device 19 is, for example, a camera, for acquiring image information of mountain vegetation in the area to be monitored; wherein,

[0040] The fixing part includes a sleeve 4 fixed to the bottom of the base plate 1, a connecting rod 6 is movably provided in the sleeve 4, one end of the connecting rod 6 passes through the bottom of the sleeve 4 and is provided with an insertion cone 5, and the collection unit is fixed to the area to be monitored through the sleeve 4 and the insertion cone 5. When installing, it is sufficient until the bottom surface of the base plate 1 contacts the installation ground of the area to be monitored;

[0041] The first windproof member includes a hollow rotating column 10 rotatably arranged between the bottom plate 1 and the top plate 2. A wind direction indicator 11 is fixedly sleeved on the outer wall of the hollow rotating column 10. The wind direction indicator 11 always indicates the direction of the wind and can drive the hollow rotating column 10 to rotate under the drive of the wind. An air inlet 12 is arranged on the outer wall of the hollow rotating column 10 in the same direction as that indicated by the wind direction indicator 11. Through this arrangement, the airflow blowing toward the collection unit can enter the hollow rotating column 10 through the air inlet 12. In order to prevent the hollow rotating column 10 from being blocked, a filter can be arranged in the air inlet 12. A one-way valve 13 is arranged in the air inlet 12 so that the airflow entering the hollow rotating column 10 will not be discharged.

[0042] A piston-connecting rod assembly 14 is provided in the hollow rotating column 10 and below the air inlet 12. The piston-connecting rod assembly 14 includes, for example, a piston and a piston rod. The bottom of the piston-connecting rod assembly 14 extends into the sleeve 4 and is connected to the connecting rod 6. The piston-connecting rod assembly 14 is driven by the incoming air to drive the connecting rod 6 to drive the insertion cone 5 to move downward. Through this arrangement, when the external wind force is strong, the wind force can be used to drive the insertion cone 5 to extend further downward into the soil at the original position, thereby increasing the depth of the insertion cone 5 entering the installation ground, increasing the connection strength between the collection unit and the installation ground, and avoiding the collapse of the collection unit.

[0043] Preferably, the image acquisition device 19 of this embodiment is connected to the output end of the rotating device 18, and the rotating device 18 is disposed on the support frame 27. For example, the rotating device 18 is a servo motor and a reducer, and the angle at which the image acquisition device 19 acquires image information can be adjusted by the rotating device 18.

[0044] Preferably, the connecting rod 6 of the present embodiment is T-shaped, and one end of the connecting rod 6 located in the sleeve 4 is slidably arranged in the sleeve 4. A groove is provided on the inner wall of one side of the connecting rod 6, and the bottom of the groove is connected to an arc-shaped clamping member 7 through an elastic member 8. The elastic member 8 is, for example, a spring. The inner wall of the sleeve 4 is provided with a plurality of groups of arc-shaped clamping grooves 9 cooperating with the arc-shaped clamping member 7 from top to bottom. Through this arrangement, when the connecting rod 6 is pushed downward, it can intermittently engage with the corresponding arc-shaped clamping grooves 9 through the arc-shaped clamping member 7, thereby providing a certain fixation for the moving connecting rod 6, but does not affect the downward movement of the connecting rod 6, so that the overall stability of the entire collection unit gradually increases with the number of times facing strong wind weather.

[0045] Preferably, a connecting plug 16 is removably inserted on the side wall of the hollow rotating column 10 of this embodiment and located above the piston connecting rod assembly 14. By unscrewing the connecting plug 16, the gas in the hollow rotating column 10 can be discharged, so as to assist in resetting the internal piston connecting rod assembly 14 during disassembly.

[0046] Example 2

[0047] As a preferred embodiment, the bottom of the hollow rotating column 10 of this embodiment is rotatably connected with a connected flow pipe 17, and a bearing and a bearing sealing ring are provided at the connection between the hollow rotating column 10 and the flow pipe 17. The flow pipe 17 is fixedly arranged in the middle of the bottom plate 1. The top of the flow pipe 17 is hollow and the bottom is closed. Both sides of the bottom plate 1 are provided with a sealing groove 21 connected to the flow pipe 17. A matching extension plate 22 is provided in the sealing groove 21. The inner end of the extension plate 22 is connected to the bottom of the sealing groove 21 through a connecting spring. The hollow rotating column 10 The piston located in the piston connecting rod assembly 14 is filled with gas, which is, for example, an inert gas. When the piston connecting rod assembly 14 moves downward, the gas is compressed into the sealing groove 21 to drive the extension plate 22 to move outward. Through this arrangement, when the external wind force is strong, the piston connecting rod assembly 14 will compress the gas downward to enter the sealing groove 21, and the gas entering the sealing groove 21 pushes the extension plate 22 to move outward, thereby increasing the contact area between the base plate 1 and the installation ground, and further preventing the collection unit from being affected by wind and collapsing.

[0048] Preferably, a notch 23 is provided at the bottom of the extension plate 22 of the present embodiment, the bottom of the notch 23 penetrates the bottom of the extension plate 22, and the outer end of the notch 23 penetrates the outer end of the extension plate 22; the notch 23 is rotatably connected with gripping spikes 24 at equal intervals through a torsion spring, and a limiting plate 20 is vertically provided on the inner wall of the notch 23 inside the gripping spike 24 to limit the gripping spike 24 from rotating inward;

[0049] When the extension plate 22 extends out of the sealing groove 21, the gripping spikes 24 rotate to a vertical state under the action of the torsion spring and contact the installation ground; through this arrangement, the contact area between the base plate 1 and the installation ground is increased while the gripping strength of the base plate 1 is increased, so that the connection strength between the base plate 1 and the installation ground is higher, thereby making it difficult for the collection unit to separate from the installation ground.

[0050] Example 3

[0051] Please see attached Figure 5

[0052] Preferably, the present embodiment further includes a second windshield member disposed outside the image acquisition device 19, the second windshield member includes a V-shaped wind guide member 30 and an arc-shaped transparent member 31 respectively connected to both ends of the V-shaped wind guide member 30, and transparent plates 32 are embedded on both side walls of the V-shaped wind guide member 30, and the arc-shaped transparent member 31 and the transparent plate 32 can be, for example, a transparent plate or transparent glass, etc., through such a configuration, so that the image acquisition device 19 located inside thereof can acquire image information;

[0053] The bottom of the second windshield is provided with a plurality of groups of sliding members slidably connected with the top plate 2, the sliding members are, for example, sliders, and the top of the top plate 2 is provided with an annular slide rail adapted to the slider; a support plate 29 is provided inside the second windshield, a rotating rod penetrating the top plate 2 is provided at the bottom center of the support plate 29, a bearing is provided at the connection between the rotating rod and the top plate 2, so that the second windshield can only rotate, the bottom end of the rotating rod extends to the top of the hollow rotating column 10 and is fixedly connected with a driven gear 25 rotatably connected with the hollow rotating column 10, one side of the driven gear 25 is meshed with a driving gear, and the driving gear is driven to rotate by a rotating device 28 provided on the top plate 2, the rotating device 28 is, for example, a servo motor and a reducer, an infrared receiver is embedded in the driven gear 25, and an infrared transmitter 26 cooperating with the infrared receiver is provided on the wind direction indicator 11;

[0054] When the infrared transmitter 26 receives the infrared signal emitted by the infrared receiver, the tip of the V-shaped air guide 30 faces the same direction as the direction indicated by the wind direction indicator 11. When the infrared transmitter 26 does not receive the infrared signal emitted by the infrared receiver, it sends a control signal to the external control module (for example, a controller, which can be installed on the top plate 2 of the acquisition unit) to drive the control module to control the rotating device 28 to work. After the infrared transmitter 26 receives the infrared signal emitted by the infrared receiver, the control module controls the rotating device 28 to close. Through this arrangement, the tip of the V-shaped air guide 30 is always facing the wind direction, and the wind blowing toward the acquisition unit is guided to flow along the side of the V-shaped air guide 30 through the V-shaped air guide 30, thereby reducing the impact of wind on the image acquisition device 19.

[0055] Preferably, the image acquisition device 19 of this embodiment is connected with a ventilation pipe 35. Specifically, the ventilation pipe 35 is connected with the outer shell of the image acquisition device 19 so that airflow enters the outer shell of the image acquisition device 19 to dissipate heat of the electrical components inside the image acquisition device 19. The ventilation pipe 35 is rotatably sleeved on the outer wall of the fixed cylinder 15, and the fixed cylinder 15 is fixedly arranged on the support plate 29. A bearing and a bearing sealing ring are provided at the connection between the ventilation pipe 35 and the fixed cylinder 15, so that the rotation of the image acquisition device 19 and the windproof member does not affect each other. The fixed cylinder 15 is connected with two groups of air inlet pipes 33 through a connecting hose 34. The two groups of air inlet pipes 33 are respectively penetrated on two groups of transparent plates 32. The cross section of the air inlet end of the air inlet pipe 33 is perpendicular to the side wall of the V-shaped air guide member 30, so that the airflow guided to flow along the side of the V-shaped air guide member 30 can enter the fixed cylinder 15 through the air inlet pipe 33 and the connecting hose 34, and then enter the image acquisition device 19 through the ventilation pipe 35 to dissipate heat for the electrical components in the image acquisition device 19.

[0056] The outer wall of the image acquisition device 19 is provided with heat dissipation holes so that the heat generated by the electrical components in the image acquisition device 19 can be discharged along with the airflow entering the image acquisition device 19 .
