Description

Technical Field

[0001] The present invention relates to the technical field of remote sensing monitoring, and particularly to a remote sensing monitoring device for grassland vegetation. Background Art

[0002] Grasslands are usually widely distributed and have complex terrains (such as plateaus and mountains), and grasslands are vulnerable to climate change (such as drought), grazing pressure, pests and diseases, etc. Therefore, it is necessary to continuously track indicators such as vegetation coverage and biomass. However, manual ground monitoring is time-consuming and laborious. If satellite or drone remote sensing is used, data of thousands of square kilometers can be quickly obtained. By using a multispectral sensor, NDVI (Normalized Difference Vegetation Index), LAI (Leaf Area Index), etc. can be obtained to quantify the vegetation growth status and achieve "dead - angle - free" monitoring, significantly reducing labor costs and time costs.

[0003] In the prior art, the commonly used vegetation monitoring means mainly rely on drone remote sensing and vertical remote sensing equipment. The vertical remote sensing equipment has a relatively high height, which increases the difficulty of movement and transportation to a certain extent. When the equipment needs to be transferred from one monitoring point to another, due to its height and weight, special transportation tools and personnel are usually required for operation. And the vertical remote sensing equipment usually needs to be fixed to the ground by pouring, and a large amount of time and effort are required to remove the pouring structure, which not only increases the transportation cost but also may cause equipment damage due to bumps and vibrations during transportation. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a remote sensing monitoring device for grassland vegetation.

[0005] To achieve the above - mentioned purpose, the present invention adopts the following technical solution: A remote sensing monitoring device for grassland vegetation, including a rod body. A multispectral vegetation monitor and an ambient light sensor are provided on the surface of the rod body. The bottom of the rod body is set as a base, and a plurality of universal wheels are fixed to the bottom of the base. A support chute is opened at the bottom of the base, and the support chute penetrates the upper and lower surfaces of the base. A support seat is slidably connected inside the chute, and the support seat is driven by a cylinder, and the cylinder is fixedly connected to the inner cavity of the base.

[0006] Preferably, the rod body is cylindrical, and a lifting chute is formed on the surface of the rod body. An installation seat is slidably connected to the inner wall of the lifting chute. The multi-spectral vegetation monitor and the ambient light sensor are respectively arranged at both ends of the installation seat. The installation seat is driven by a driving component. Existing vertical remote sensing devices mainly complete monitoring through a multi-spectral vegetation monitor and an ambient light sensor. After long-term use, the multi-spectral vegetation monitor and the ambient light sensor need to be regularly overhauled. The multi-spectral vegetation monitor and the ambient light sensor are usually arranged at a relatively high position, and workers need to use climbing tools for overhaul, which is not only time-consuming and laborious, but also has a relatively high safety hazard. To address such problems, the present invention adopts a liftable installation seat. The installation seat integrates a multi-spectral vegetation monitor and an ambient light sensor. By driving the installation seat to lift through the driving component, it is convenient for workers to overhaul the multi-spectral vegetation monitor and the ambient light sensor without the need for tools, which is not only time-saving and laborious, but also eliminates the safety hazard.

[0007] Preferably, the driving component includes a gear. The gear is rotationally connected to an internal extension of the installation seat. A rack is formed on the inner wall of the rod body, and the rack meshes with the gear. A bearing seat is fixed on one side of the internal extension of the installation seat. A worm is rotatably connected between the bearing seats through bearings. A worm gear meshes with the surface of the worm. The worm gear is fixedly connected to the gear, and the worm is driven by a worm rotation motor. The housing of the worm rotation motor is slidably connected to the inner wall of the rod body. By driving the worm to rotate through the worm rotation motor, the worm drives the worm gear to rotate, the worm gear drives the gear to rotate, and the gear drives the installation seat to lift on the surface of the rack.

[0008] Preferably, the helix angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm and the worm gear. When the helix angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm and the worm gear, the worm and worm gear structure has self-locking property, that is, the worm can drive the worm gear to rotate, but the worm gear cannot drive the worm to rotate, which improves the stability of the installation seat and also facilitates adjusting the position of the installation seat.

[0009] Preferably, the multi-spectral vegetation monitor and the ambient light sensor are respectively detachably connected to both ends of the installation seat. The detachable connection further improves the disassembly and assembly efficiency of workers, thereby improving the overhaul efficiency of the multi-spectral vegetation monitor and the ambient light sensor, which is time-saving and laborious.

[0010] Preferably, photovoltaic panels are fixed on both sides of the top of the rod body. The output end of the photovoltaic panel is electrically connected to an inverter. The multispectral vegetation monitor and the ambient light sensor are respectively electrically connected to the inverter. The photovoltaic panels are installed on both sides of the top of the rod body, converting solar energy into electrical energy. The photovoltaic materials inside the photovoltaic panels convert light energy into direct current through the photovoltaic effect. The direct current output by the photovoltaic panels is connected to the inverter. The inverter converts the direct current generated by the photovoltaic panels into alternating current and can also stabilize and regulate the electrical energy to ensure the stability of the output voltage and current. The multispectral vegetation monitor obtains energy through the alternating current provided by the inverter and monitors the spectral characteristics of vegetation, such as the wavelength and intensity of reflected light. It emits light of specific wavelengths and receives the light reflected by the vegetation to analyze information such as the health status, growth state, and photosynthesis efficiency of the vegetation. The ambient light sensor also operates through the alternating current provided by the inverter. Its main function is to measure the light intensity and spectral distribution in the surrounding environment. These data can be used to calibrate the measurement results of the multispectral vegetation monitor or to analyze the impact of ambient light on vegetation growth.

[0011] Preferably, anti-slip patterns are arrayed on the bottom of the support base. The anti-slip patterns increase the friction between the bottom of the support base and the ground, further improving the stability of the vertical remote sensing device.

[0012] Beneficial Effects In the prior art, the commonly used vegetation monitoring methods mainly rely on unmanned aerial vehicle remote sensing and vertical remote sensing devices. The vertical remote sensing devices are relatively tall, which increases the difficulty of movement and transportation to a certain extent. When the device needs to be transferred from one monitoring point to another, due to its height and weight, special transportation tools and personnel are usually required for operation. And the vertical remote sensing devices usually need to be fixed to the ground by pouring, which requires a lot of time and effort to remove the pouring structure. This not only increases the transportation cost but also may cause device damage due to bumps and vibrations during transportation. To solve such problems, the present invention adopts universal wheels to facilitate the movement and handling of the vertical remote sensing device. And after the vertical remote sensing device is transported to another monitoring point, to prevent the vertical remote sensing device from being affected by wind, the cylinder is driven to move the support base downward until the support base is pressed against the ground, preventing the vertical remote sensing device from shaking in strong winds, facilitating the transportation of the device and improving the stability of the device at the same time.

[0016] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. Specific embodiment: Refer to Figure 1-6 , a grassland vegetation remote sensing monitoring device, including a rod body 1, on the surface of the rod body 1 there are arranged a multispectral vegetation monitor 2 and an ambient light sensor 3, the bottom of the rod body 1 is a base 4, at the bottom of the base 4 there are fixed a plurality of universal wheels 14, at the bottom of the base 4 there is provided a support chute, and the support chute penetrates through the upper and lower surfaces of the base 4, inside the chute there is a slidably connected support base 7, the support base 7 is driven by a cylinder 8, the cylinder 8 is fixedly connected to the inner cavity of the base 4, at the bottom of the support base 7 there are arranged anti-slip lines in an array, and the anti-slip lines increase the friction between the bottom of the support base 7 and the ground, further improving the stability of the vertical remote sensing device.

[0018] The rod body 1 is designed to be cylindrical, and a lifting chute 101 is provided on the surface of the rod body 1. An installation seat 6 is slidably connected to the inner wall of the lifting chute 101. The multispectral vegetation monitor 2 and the ambient light sensor 3 are respectively arranged at both ends of the installation seat 6. The installation seat 6 is driven by a driving component. The existing vertical remote sensing equipment mainly completes monitoring through the multispectral vegetation monitor 2 and the ambient light sensor 3. After long-term use, the multispectral vegetation monitor 2 and the ambient light sensor 3 need to be regularly overhauled. The multispectral vegetation monitor 2 and the ambient light sensor 3 are usually arranged at a relatively high position, and workers need to use climbing tools for overhaul, which is not only time-consuming and laborious, but also has a relatively high safety hazard. To solve such problems, the present invention adopts a liftable installation seat 6. The installation seat 6 integrates the multispectral vegetation monitor 2 and the ambient light sensor 3. By driving the installation seat 6 to lift through the driving component, it is convenient for workers to overhaul the multispectral vegetation monitor 2 and the ambient light sensor 3 without using tools, which is not only time-saving and laborious, but also eliminates the safety hazard. The driving component includes a gear 10. The gear 10 is rotationally connected to the inner extension of the installation seat 6. A rack 9 is provided on the inner wall of the rod body 1, and the rack 9 meshes with the gear 10. A bearing seat is fixed on one side of the inner extension of the installation seat 6. A worm 12 is rotatably connected between the bearing seats through bearings. A worm gear 11 meshes with the surface of the worm 12. The worm gear 11 is fixedly connected to the gear 10, and the worm 12 is driven by a worm rotation motor 13. The housing of the worm rotation motor 13 is slidably connected to the inner wall of the rod body 1. By driving the worm 12 to rotate through the worm rotation motor 13, the worm 12 drives the worm gear 11 to rotate, and the worm gear 11 drives the gear 10 to rotate. The gear 10 drives the installation seat 6 to lift on the surface of the rack 9. The helix angle of the worm 12 is smaller than the equivalent friction angle between the meshing teeth of the worm 12 and the worm gear 11. When the helix angle of the worm 12 is smaller than the equivalent friction angle between the meshing teeth of the worm 12 and the worm gear 11, the worm and worm gear structure has self-locking property, that is, the worm 12 can drive the worm gear 11 to rotate, but the worm gear 11 cannot drive the worm 12 to rotate, which improves the stability of the installation seat 6 and also facilitates the adjustment of the position of the installation seat 6.

[0019] The multispectral vegetation monitor 2 and the ambient light sensor 3 are respectively detachably connected to both ends of the installation seat 6. The detachable connection further improves the disassembly and assembly efficiency of workers, thereby improving the overhaul efficiency of the multispectral vegetation monitor 2 and the ambient light sensor 3, which is time-saving and laborious.

The multispectral vegetation monitor 2 and the ambient light sensor 3 are respectively electrically connected to the inverter. The photovoltaic panels 5 are installed on both sides of the top of the rod body 1, converting solar energy into electrical energy. The photovoltaic materials inside the photovoltaic panels 5, such as silicon, convert light energy into direct current through the photovoltaic effect. The direct current output by the photovoltaic panels 5 is connected to the inverter, and the inverter converts the direct current generated by the photovoltaic panels 5 into alternating current, and can also stabilize and regulate the electrical energy to ensure the stability of the output voltage and current. The multispectral vegetation monitor 2 obtains energy through the alternating current provided by the inverter and monitors the spectral characteristics of the vegetation, such as the wavelength and intensity of the reflected light. It emits light of specific wavelengths such as red light and near-infrared light and receives the light reflected by the vegetation to analyze information such as the health status, growth state, and photosynthesis efficiency of the vegetation. The ambient light sensor 3 also operates through the alternating current provided by the inverter. Its main function is to measure the light intensity and spectral distribution in the surrounding environment. These data can be used to calibrate the measurement results of the multispectral vegetation monitor or to analyze the impact of ambient light on vegetation growth.

[0021] Working principle of the present invention: After the vertical remote sensing device is transported to another monitoring point, the air cylinder 8 is opened to drive the support base 7 to move downward until the support base 7 is pressed against the ground. When it is necessary to repair the multispectral vegetation monitor 2 and the ambient light sensor 3, the worm rotary motor 13 is opened to drive the worm 12 to rotate. The worm 12 drives the worm gear 11 to rotate, and the worm gear 11 drives the gear 10 to rotate. The gear 10 drives the mounting seat 6 to lift and lower on the surface of the rack 9, lowering the multispectral vegetation monitor 2 and the ambient light sensor 3 to a low position for the staff to repair the multispectral vegetation monitor 2 and the ambient light sensor 3.
