Description

Technical Field

[0001] This invention relates to the field of remote sensing monitoring technology, and in particular to a remote sensing monitoring device for vegetation restoration in soil and water conservation. Background Technology

[0002] Dynamic monitoring of soil and water conservation and vegetation restoration is an important foundation for regional ecological governance and soil erosion control. At present, multispectral remote sensing and lidar remote sensing technologies are mostly used to conduct routine monitoring of vegetation coverage, vegetation growth and surface topography.

[0003] Currently, most of the sensor equipment used for remote sensing monitoring of vegetation restoration in the field is deployed in a fixed outdoor location. It is exposed to complex outdoor environments for a long time and has many technical defects. Existing equipment mostly uses a single sensor to collect data independently, which makes it difficult to achieve synchronous and sequential, same-view linkage acquisition of multispectral and lidar sensors. The matching of monitoring data is poor, and it is difficult to collect meteorological parameters such as wind speed and rainfall at the same time. It is also difficult to correct meteorological errors in remote sensing data, resulting in insufficient accuracy of vegetation restoration monitoring results.

[0004] Therefore, this application provides a remote sensing monitoring device for vegetation restoration in soil and water conservation to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a remote sensing monitoring device for vegetation restoration for soil and water conservation, so as to solve the problem that it is difficult to achieve synchronous and sequential data acquisition from the same viewpoint.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A remote sensing monitoring device for vegetation restoration in soil and water conservation includes a frame with a placement platform. A multispectral intelligent sensor and a lidar sensor are mounted on the placement platform. An intelligent protection component is installed outside the multispectral intelligent sensor and the lidar sensor. An automatic cleaning component is installed inside the placement platform. A synchronous acquisition component is also installed on the placement platform. The intelligent protection component automatically opens and closes according to the operating status of the multispectral intelligent sensor and the lidar sensor, achieving sealed protection when the sensors are idle and open exposure when they are in operation. The automatic cleaning component works in conjunction with the intelligent protection component: when the intelligent protection component is in its operating state... When the intelligent protection component is in its closed protective state, it lowers the automatic cleaning component into the placement platform to ensure unobstructed operation of the sensors. When the intelligent protection component is in its closed protective state, it raises the automatic cleaning component and lifts the synchronous acquisition component, simultaneously cleaning the detection surfaces of the multispectral intelligent sensor and the lidar sensor. The synchronous acquisition component works in conjunction with the intelligent protection component: when the intelligent protection component is open, it raises the synchronous acquisition component to remove the obstruction, allowing the multispectral intelligent sensor and the lidar sensor to simultaneously collect vegetation remote sensing data; when the intelligent protection component is closed, it lowers the synchronous acquisition component to shield the sensor surfaces, preparing for the next synchronous acquisition.

[0007] Optionally, a limiting baffle is provided on the placement platform, and several rollers are installed on the inner side of the limiting baffle. A reference platform is fixedly connected to the placement platform. The reference platform is semi-circular, and two sliding grooves are vertically opened on the arc-shaped end face of the reference platform. The two sliding grooves are respectively vertically sliding and cooperating with the automatic cleaning component.

[0008] Optionally, the intelligent protection component includes a left protective plate and a right protective plate. The left and right protective plates are both clamped between the inner roller of the limiting baffle and the reference platform and form a rotatable connection. A flip motor is installed on the outer side of the left and right protective plates to drive them to flip and open. A trigger rod is fixedly connected to the bottom inner side of the left and right protective plates. The trigger rod is slidably embedded in the groove of the reference platform. A trigger plate is fixedly connected to the trigger rod. The trigger plate is in transmission cooperation with the automatic cleaning component and drives it to rise and fall vertically.

[0009] Optionally, a rotating rod is fixedly connected to the inner side of both the left and right protective plates. The rotating rod is coaxially arranged with the drive shaft of the corresponding flip motor. A gear is fixedly sleeved on the rotating rod. The gear meshes with the synchronous acquisition component to drive its vertical displacement.

[0010] Optionally, an environmental sensor is embedded on the outer side of the right protective plate. The environmental sensor is used to collect real-time meteorological data on wind speed and rainfall in the field environment to assist in the correction of remote sensing monitoring data for vegetation restoration.

[0011] Optionally, the automatic cleaning component includes a base plate on which a small motor is mounted. A flexible cleaning brush is driven to the output end of the small motor. The bottom of the base plate abuts against a trigger plate, and the entire assembly is vertically raised and lowered by the sliding motion of the trigger plate along with the trigger rod.

[0012] Optionally, four fixed connectors are fixedly connected to the top of the inner wall of the reference platform. A sliding rod is fixedly connected to each fixed connector. An opening and closing door is slidably sleeved on the sliding rod. A hinge seat is installed on the upper surface of the base plate and the bottom of the opening and closing door. A hinge rod is hinged to the two sets of hinge seats. A top frame is fixedly connected to the base plate. After the top frame is raised with the base plate, it pushes the synchronous acquisition component to achieve displacement linkage.

[0013] Optionally, the synchronous acquisition component includes two slides symmetrically fixed on the placement platform. Each slide has a sleeve vertically slidably connected inside it. A movable rod is telescopically slidably connected inside the sleeve. A slider is fixedly connected to the top of the movable rod. A fixed rod is fixedly connected to the side of the slider. A baffle is installed on the fixed rod. The baffle is set facing the mirror surface of the multispectral intelligent sensor and the lidar sensor to block the sensor's detection light path.

[0014] Optionally, a vertically arranged toothed plate is fixedly connected to the outer side of the bottom of the sleeve, and the toothed plate meshes with the gear on the rotating rod for transmission.

[0015] Optionally, the bottom surface of the fixed rod abuts against the top surface of the top frame, and the top frame pushes the fixed rod upward as the base plate is raised, causing the slider, moving rod and baffle to move vertically as a whole.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, an intelligent protective component is set up to automatically flip open and close according to the sensor's working status. When idle, it forms a sealed protective structure, which protects the sensor from dust, rain, sun, and contamination by debris. When working, it automatically opens to expose the detection angle. The component uses rollers to rotate in coordination with the reference platform. The flipping process is smooth and stable. It can be linked with the automatic cleaning component and the synchronous acquisition component to achieve mechanical timing coordination. At the same time, it is equipped with an environmental sensor to collect wind speed and rainfall meteorological data in a time-sharing manner, providing meteorological correction and error compensation for remote sensing monitoring data. It has strong adaptability to the field and reduces manual operation and maintenance costs.

[0017] By setting up an automatic cleaning component that works in conjunction with the intelligent protection component, automatic lifting and lowering is achieved. When open, it is retracted and hidden, completely avoiding the sensor's detection optical path and not affecting normal remote sensing data acquisition. When closed, it automatically rises and uses a flexible cleaning brush to gently wipe the sensor mirror, removing dust, moisture, and debris while cleaning without scratching the optical mirror. A four-bar linkage structure drives the automatic opening and closing of the door, sealing and protecting the internal sliding transmission structure of the equipment. This achieves self-cleaning and internal dust and water protection in one integrated system. The structural linkage is reliable and significantly reduces the frequency of maintenance for field equipment.

[0018] By setting up a synchronous acquisition component, the overall synchronous lifting and lowering is achieved through gear and toothed plate meshing transmission. It can accurately switch the sensor optical path blocking and opening states, ensuring that the multispectral sensor and lidar sensor acquire data synchronously from the same perspective and in the same sequence. The sleeve and moving rod extend and retract to match the lifting stroke, and the mechanical linkage achieves orderly interlocking of protection, acquisition and cleaning actions. The whole adopts a pure mechanical transmission structure, which does not require additional power drive. It is stable in operation, has low energy consumption and high synchronization accuracy, and is suitable for long-term unattended monitoring in the field, effectively improving the accuracy and consistency of vegetation restoration remote sensing monitoring data.

[0021] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0022] like Figures 1 to 11As shown, an embodiment of the present invention provides a remote sensing monitoring device for vegetation restoration in soil and water conservation, including a frame 1. A platform 2 is fixedly installed on the frame 1, serving as an integral support base for supporting various functional components. A multispectral intelligent sensor 6 and a lidar sensor 7 are symmetrically arranged on the platform 2. The device achieves integrated remote sensing monitoring of vegetation coverage, vegetation growth, and topography in the soil and water conservation area through the combination of these two sensors. An intelligent protective component 3 surrounds the multispectral intelligent sensor 6 and the lidar sensor 7. An automatic cleaning component 4 is embedded inside the platform 2. A synchronous acquisition component 5 is also installed on the platform 2 corresponding to the sensor positions. The intelligent protective component 3 can automatically flip open and close according to the working start / stop status of the multispectral intelligent sensor 6 and the lidar sensor 7. When the field monitoring operation is idle, the intelligent protective component 3 closes to form a sealed cover, protecting the two sensors from dust, rain, and sun. When monitoring is in operation, the intelligent protective component 3 flips open, allowing the sensors to be fully exposed for unobstructed detection. The automatic cleaning component 4 and the intelligent protective component 3 form a mechanical linkage: when the intelligent... When the protective component 3 flips open to enter the working state, it simultaneously drives the automatic cleaning component 4 to descend into the internal cavity of the placement platform 2, completely avoiding the sensor's detection field of view and not affecting the normal remote sensing operation of multispectral and lidar sensors. When the monitoring is completed, the intelligent protective component 3 flips closed to enter the protective state, simultaneously driving the automatic cleaning component 4 to rise upward. During the lifting process, it simultaneously lifts the synchronous acquisition component 5 and precisely approaches the detection mirrors of the multispectral intelligent sensor 6 and lidar sensor 7, completing the automatic cleaning of dust, water vapor, and debris on the mirrors, ensuring the accuracy of imaging and ranging in the next monitoring. The synchronous acquisition component 5 also forms a linkage and transmission with the intelligent protective component 3: when the intelligent protective component 3 flips open, it drives the synchronous acquisition component 5 to rise synchronously through the meshing transmission of gear 307, removing the obstruction of the sensor detection mirrors, enabling the multispectral intelligent sensor 6 and lidar sensor 7 to carry out remote sensing data acquisition for soil and water conservation and vegetation restoration synchronously in time sequence and from the same perspective. When the intelligent protective component 3 flips closed, it drives the synchronous acquisition component 5 to descend and reset, preparing the mechanical and optical paths for the next synchronous data acquisition.

[0023] like Figures 3 to 7As shown, a limiting baffle 201 is fixedly installed on the placement platform 2. The limiting baffle 201 has an enclosed structure, and several rollers 202 are evenly spaced on the inner side of the limiting baffle 201. The rollers 202 can reduce the frictional resistance of the protective plate when it is turned over and ensure smooth rotation. A reference platform 203 is fixedly connected in the center of the placement platform 2. The reference platform 203 is set as a semi-circular structure, which plays a role in positioning, guiding and supporting. Two sliding grooves 204 are symmetrically opened vertically on the arc-shaped end face of the reference platform 203. The two sliding grooves 204 have a vertical through structure and form a vertical sliding guide cooperation with the moving parts of the automatic cleaning component 4, which restricts the automatic cleaning component 4 to move smoothly up and down only in the vertical direction and avoids deviation and jamming.

[0024] like Figure 5 and Figure 8 As shown, the intelligent protection component 3 includes a left protective plate 301 and a right protective plate 302 arranged symmetrically. Both the left and right protective plates 301 and 302 are clamped between a roller 202 mounted inside a limiting baffle 201 and a semi-circular reference platform 203, forming a stable rotating connection structure. A flip motor 303 is fixedly installed on the outer side of both the left and right protective plates 301 and 302, serving as a power source to drive the corresponding protective plates to flip and open at fixed points. A trigger rod 304 is vertically fixedly connected to the bottom inner side of both the left and right protective plates 301 and 302. The trigger rod 304 is vertically slidably embedded in the corresponding groove 204 of the reference platform 203, and moves along the groove 204 in a combined arc and vertical motion as the protective plate flips. A trigger plate 305 is fixedly connected to the top of the trigger rod 304. The trigger plate 305 is a horizontally stressed structure that forms a resistance with the top of the automatic cleaning component 4. With the transmission mechanism in place, the automatic cleaning component 4 can be driven to rise and fall vertically as the displacement of the trigger rod 304 changes. Rotating rods 306 are fixedly connected to the inner sides of the left protective plate 301 and the right protective plate 302. The rotating rods 306 are coaxially set with the drive shaft of the corresponding flip motor 303 and rotate coaxially with the motor. A gear 307 is fixedly fitted on the rotating rod 306. The gear 307 rotates synchronously with the rotating rod 306 and forms a meshing transmission with the synchronous acquisition component 5, converting the rotational motion into the vertical linear displacement of the synchronous acquisition component 5. An environmental sensor 308 is embedded in the outer wall of the right protective plate 302 without occupying additional installation space. The environmental sensor 308 is used to collect environmental wind speed and rainfall meteorological data of the monitoring area in real time in the field. It can be used for meteorological correction and error compensation of subsequent vegetation remote sensing monitoring data, improving the accuracy and reliability of soil and water conservation vegetation restoration monitoring results.

[0025] like Figure 3 , Figure 4 , Figure 7 and Figure 9As shown, the automatic cleaning assembly 4 includes a horizontally arranged base plate 401, which serves as the integral support and mounting base. A small motor 402 is fixedly mounted on the upper surface of the base plate 401. The output end of the small motor 402 is connected to a flexible cleaning brush 403. The flexible cleaning brush 403 is made of soft and wear-resistant material, which can flexibly wipe the sensor mirror surface without scratching the optical mirror. The bottom surface of the base plate 401 forms a vertical abutment with the upper surface of the trigger plate 305. The trigger plate 305 slides in the slide groove 204 following the trigger rod 304, directly pushing or lowering the base plate 401, thereby driving the entire automatic cleaning assembly 4 to achieve smooth vertical lifting and lowering. Four fixed connectors 404 are fixedly connected in a ring at the top of the inner wall of the reference platform 203. The four fixed connectors 404 are arranged in a rectangle to ensure force distribution. The uniform, fixed connecting piece 404 is fixedly connected to a sliding rod 405, and an opening and closing door 406 is slidably sleeved on the sliding rod 405. The opening and closing door 406 can slide vertically along the sliding rod 405 to realize the automatic opening and closing sealing of the internal cavity of the placement platform 2. The upper surface of the base plate 401 and the bottom of the opening and closing door 406 are respectively installed with hinge seats 407. The upper and lower sets of hinge seats 407 are hinged together with a hinge rod 408, forming a four-bar linkage mechanism. When the base plate 401 is raised and lowered, the opening and closing door 406 is pushed and pulled synchronously through the hinge rod 408 to realize the opening and closing of the cavity. The upper side of the base plate 401 is also vertically fixedly connected to a top frame 409. The top frame 409 is a rigid pushing structure that rises and falls synchronously with the base plate 401. During the lifting process, it pushes the synchronous acquisition component 5 upward to realize the mechanical displacement linkage between the two components.

[0026] like Figures 10 to 11As shown, the synchronous acquisition component 5 includes two slide rails 501 symmetrically fixed on the placement platform 2. The two slide rails 501 are arranged in parallel vertically to provide linear guidance for the sliding components. Each slide rail 501 has a sleeve 502 vertically slidably mounted inside. The sleeve 502 can slide up and down along the slide rail 501 without jamming. The sleeve 502 is hollow inside and is slidably connected to a moving rod 503. The moving rod 503 can be vertically extended and retracted inside the sleeve 502 to adapt to height linkage requirements. A slider 504 is fixedly connected to the top of the moving rod 503. The slider 504 is vertically slidably adapted to the slide rail 501. A fixing rod 505 is horizontally fixedly connected to the slider 504. A sensor baffle 506 is fixedly installed on the outer end of the fixing rod 505. The sensor baffle 506 is horizontally positioned facing the detection mirror of the multispectral intelligent sensor 6 and the lidar sensor 7, and can be raised and lowered with the mechanism for precise positioning. The optical path of the sensor is partially blocked or avoided, enabling switching between optical path blocking and synchronous acquisition. A toothed plate 507 is vertically fixedly connected to the outer bottom of the sleeve 502. The toothed plate 507 is a vertical straight rack structure. The toothed plate 507 meshes with the gear 307 on the rotating rod 306 to transmit power, converting the rotational power of the flip motor 303 into the vertical linear motion of the toothed plate 507 and the sleeve 502, realizing the synchronous lifting and lowering of the two sets of synchronous acquisition components 5. The bottom surface of the fixed rod 505 and the top end face of the top frame 409 form a vertical abutment fit. When the top frame 409 rises synchronously with the bottom plate 401, it pushes the fixed rod 505 upward, thereby driving the slider 504, the moving rod 503 and the sensor baffle 506 to move vertically in sync, which facilitates the operation of the flexible cleaning brush 403. The structure is compact and the action is synchronized, making it suitable for long-term unattended remote sensing monitoring of soil and water conservation vegetation in the field.

[0027] The working principle of the technical solution provided by this invention is as follows: When the device is in standby protection mode, the left protective plate 301 and right protective plate 302 of the intelligent protection component 3 are completely closed. At this time, the trigger rod 304 is positioned with the protective plate, so that the trigger plate 305 abuts against the lower end face of the base plate 401 of the automatic cleaning component 4, and the automatic cleaning component 4 is vertically lifted to the position above the opening and closing door 406. The top frame 409 fixed on the base plate 401 pushes the fixed rod 505 of the synchronous acquisition component 5 upward, so that the moving rod 503 slides upward relative to the sleeve 502, thereby driving the slider 504, the fixed rod 505 and the sensor baffle 506 to move upward synchronously. The sensor baffle 506 leaves the position of the sensor light path blockage. At the same time, the flexible cleaning brush 403 driven by the small motor 402 on the automatic cleaning component 4 precisely fits the detection mirror of the multispectral intelligent sensor 6 and the lidar sensor 7, and performs flexible rotation wiping to remove dust, water vapor and small debris from the mirror surface, which not only ensures the monitoring accuracy, but also avoids scratching the optical mirror surface.

[0028] When the intelligent protection component 3 is in the closed state, the environmental sensor 308 embedded on the outside of the right protective plate 302 is exposed and works normally. It can collect real-time online meteorological data of wind speed and rainfall in the monitoring area, which is used for meteorological correction and error compensation of subsequent vegetation remote sensing monitoring data, effectively improving the accuracy and reliability of soil and water conservation vegetation restoration monitoring results.

[0029] When remote sensing data acquisition is required, the flip motor 303 drives the left protective plate 301 and the right protective plate 302 to flip and open synchronously. The trigger rod 304 slides along the slide groove 204 of the reference platform 203 as the protective plate flips, driving the trigger plate 305 to move downward synchronously, releasing the top support limit on the base plate 401. After the trigger plate 305 moves down, the base plate 401 and the entire automatic cleaning assembly 4 fall down synchronously. The top frame 409 no longer pushes the fixed rod 505 upward, and the moving rod 503 loses its upward support force. Under its own gravity, it falls back to the bottom of the sleeve 502 relative to the sleeve 502, driving the sensor baffle 506 to move downward and reset, temporarily blocking the detection optical path of the multispectral intelligent sensor 6 and the lidar sensor 7.

[0030] As the intelligent protection component 3 flips open, the flip motor 303 drives the coaxially connected rotating rod 306 and gear 307 to rotate synchronously. The gear 307 meshes with the toothed plate 507 of the synchronous acquisition component 5 for transmission. After the sensor baffle 506 briefly falls back to block the light path, the gear 307 continues to drive the toothed plate 507 and the sleeve 502 to slide upward along the slide rail 501 as a whole. The sleeve 502 drives the moving rod 503, the slider 504, the fixed rod 505 and the sensor baffle 506 to move upward together. The sensor baffle 506 avoids the light path again and no longer blocks the detection light path. The multispectral intelligent sensor 6 and the lidar sensor 7 are exposed and synchronously carry out remote sensing data acquisition for vegetation restoration.

[0031] As the trigger plate 305 moves downward with the trigger rod 304 and the automatic cleaning component 4 descends and is stored, the upper surface of the base plate 401 and the bottom of the opening and closing door 406 are respectively hinged to the hinge rod 408 through the hinge seat 407, forming a four-bar linkage structure. When the base plate 401 descends, the top of the hinge rod 408 moves towards the middle, causing the opening and closing door 406 to slide vertically and close along the sliding rod 405. When the automatic cleaning component 4 is completely inserted into the internal cavity of the reference platform 203, the opening and closing door 406 is completely closed, forming a dustproof and waterproof seal for the transmission and sliding components inside the placement platform 2.

[0032] When remote sensing data acquisition is completed and the intelligent protection component 3 changes from open to closed and reset, the mechanism operates in a reverse logic sequence: First, gear 307 meshes with toothed plate 507, driving sleeve 502 and synchronous acquisition component 5 to move downwards and into position, causing sensor baffle 506 to fall back first to block the sensor's detection light path, completing standby light-blocking and dust prevention. Then, left protective plate 301 and right protective plate 302 are completely closed, trigger plate 305 pushes upwards again against the push base plate 401, driving automatic cleaning component 4 to move upwards and return to position. At the same time, top frame 409 gently lifts the synchronous acquisition component 5, which is already in the blocked state, for fine adjustment, so that the flexible cleaning brush 403 accurately fits the sensor mirror surface, preparing for the next mirror cleaning operation.

[0033] In addition, the environmental sensor 308 has a time-sharing operation characteristic: it only works normally when the intelligent protection component 3 is closed and exposed, collecting real-time meteorological data such as wind speed and rainfall in the field. When the intelligent protection component 3 is fully opened, the environmental sensor 308 is stored and hidden inside the structure with the protective plate, and cannot be exposed to collect data. It enters a dormant protection state, which not only avoids invalid sampling, but also protects the environmental sensor 308 body in the field and extends the service life of the equipment.

[0034] The entire machine is supported by the frame 1 and the placement platform 2. The rotation and sliding guidance are provided by the limit baffle 201, roller 202 and reference platform 203. The linkage sequence of each component is clear and the action interlock is precise. No manual intervention is required. It can adapt to complex field conditions for a long time and stably complete the remote sensing dynamic monitoring task of vegetation restoration in soil and water conservation areas.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
