Description

Technical Field

[0001] This invention relates to the field of information acquisition technology, and more specifically, to a long-distance land planning geographic information survey and acquisition system based on network interaction. Background Technology

[0002] With the development of refined and information-based land spatial planning, long-distance land planning geographic information surveying and collection has placed higher demands on the efficiency, accuracy, and coverage of data acquisition. Traditional surveying methods rely on manual field operations, which have limitations such as long cycles, high costs, and poor terrain adaptability, making it difficult to meet the real-time needs of large-scale, long-distance land surveying. Against this backdrop, UAV surveying technology, with its advantages of mobility, high operational efficiency, accurate data acquisition, and ability to cover complex terrain, has become the core operational carrier in long-distance land planning geographic information surveying and collection systems, and is widely used in scenarios such as land boundary surveying, land use status surveys, ecological environment monitoring, and site selection for planning projects.

[0003] The long-distance land planning geographic information survey and acquisition system based on network interaction uses drones equipped with high-definition cameras, lidar, GPS positioning and other sensors to collect geospatial data in real time. With the help of network technologies such as 5G and satellite communication, the survey data is remotely transmitted to the back-end processing center, realizing remote control of survey operations, real-time data analysis and sharing, which greatly improves the intelligence level and operation radius of land planning surveys. However, drones face multiple challenges in long-distance survey operations, such as complex natural environments, external interference and operational risks. The safety of the equipment directly determines the success or failure of the survey task and the integrity of the data. Drone protection technology has become a key support for ensuring the stable operation of the system.

[0004] Currently, there are many shortcomings in the protection of drones in land surveying scenarios. In terms of natural environment protection, long-distance surveys often involve complex areas such as mountains. Obstacles in complex terrain, such as trees, buildings, and high-voltage lines, are prone to collisions with drones, causing equipment damage. In terms of self-protection, the existing protective structures of drones are mostly general-purpose rigid protections, which are large in size, heavy in weight, and have poor adaptability. This increases the drone's load burden and shortens its flight range. More importantly, the existing protective structures are mostly fixed in shape and cannot be dynamically adjusted according to the operation scenario. When it is necessary to flexibly move through complex terrain, fixed protective structures can easily increase flight resistance or cause entanglement risks. When operating in open areas, it is difficult to provide comprehensive protective coverage, making it difficult to balance the protective effect and the operation efficiency. Therefore, we provide a long-distance land planning geographic information surveying and acquisition system based on network interaction. Summary of the Invention

[0005] The purpose of this invention is to provide a network-interactive long-distance land planning geographic information survey and acquisition system to solve the problems mentioned in the background art above: In terms of self-protection, the existing protective structures of drones are mostly general-purpose rigid protection, which has the problems of large size, heavy weight and poor adaptability. This increases the drone's load and shortens its flight time. More importantly, the existing protective structures are mostly fixed in shape and cannot be dynamically adjusted according to the operation scenario. When it is necessary to flexibly move through complex terrain, the fixed protective structure is prone to increasing flight resistance or causing entanglement risk. When operating in open areas, it is difficult to provide comprehensive protective coverage, making it difficult to balance the protective effect and the operation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This network-interactive long-distance land planning geographic information surveying and acquisition system includes unmanned aerial vehicles (UAVs). Using UAVs as the core execution platform and relying on real-time network interaction technology, the system achieves accurate and efficient surveying and acquisition of geographic information within long-distance land planning areas. The overall process is divided into five stages: task assignment, main operation, data feedback, interactive verification, and task completion, as detailed below: During the network interaction task issuance phase, the ground control center, based on the needs of land planning, delineates the long-distance survey area and sets the data collection parameters, such as elevation measurement accuracy, land feature type identification range, and flight path altitude. The task instructions are transmitted to the UAV's airborne control system via 4G, 5G, or satellite networks. After receiving the instructions, the UAV automatically verifies the feasibility of the task, such as whether the battery life covers the survey area and whether the no-fly zone is avoided. It then sends the task confirmation information back to the ground center via the network, forming a two-way network interaction closed loop from the ground to the air. During the autonomous survey and data acquisition phase, the UAV takes off along a preset route and enters the long-distance survey area. It then uses onboard equipment such as a multispectral camera, lidar, and GPS positioning module to collect geographic information. The lidar is responsible for collecting terrain elevation data and three-dimensional structure data of ground features. The multispectral camera captures spectral information such as surface vegetation cover and land use type. The GPS module records the UAV's position coordinates in real time to ensure that the collected data is accurately matched with the geographic spatial location. During the acquisition process, the UAV's onboard sensors perform preliminary screening of the raw data through an edge computing module. At the same time, the UAV transmits information such as acquisition progress and equipment operating status to the ground center in real time via the network. During the real-time data transmission and dynamic adjustment phase, the UAV, relying on a high-bandwidth, low-latency network, transmits the pre-processed geographic information data, such as topographic point cloud data and ground feature spectral images, back to the ground control center in real time. The geographic information system at the ground center quickly analyzes and visualizes the transmitted data, allowing land planning personnel to view the geographic information of the surveyed area in real time. If incomplete data collection is found in a local area, the ground center can send dynamic adjustment commands to the UAV via the network. After receiving the commands, the UAV automatically changes its flight path, adjusts its flight altitude, or re-collects data, realizing a real-time network interactive operation mode from data collection to feedback and then to adjustment. During the multi-terminal network interaction data verification phase, after the UAV completes the data collection task in the preset area, it packages all the raw data and the preliminary processed data and transmits them to multiple terminal nodes such as the ground center and cloud server through the network. The ground center and cloud server cross-verify the data to verify the accuracy and consistency of the data. At the same time, the system supports land planning personnel from multiple terminals to access cloud data through the network for collaborative review to ensure that the collected data meets the technical standards of land planning. After the mission concludes and data archiving phase, and data verification is successful, the ground center sends a return command to the UAV via the network. The UAV autonomously returns and is recovered. The cloud server categorizes and archives the finally verified geographic information data, forming a standardized land planning geographic information database for subsequent land spatial planning, resource surveys, and other work. The entire process achieves efficient data flow and management through network interaction. The UAV is externally fixedly connected to four support rods, symmetrically distributed, with each rod having an L-shaped structure. A support plate is fixedly connected to the outer end of each support rod, away from the UAV. The four support plates are divided into two groups, with opposing groups forming one group. These two groups of support plates have inner and outer sections. A first protective strip is fixedly connected to the outside of the support plate. A rotating plate is rotatably connected to the outside of the support plate near the drone. There are four rotating plates in total, and the four rotating plates are symmetrically distributed. A second protective strip is fixedly connected to the outside of the rotating plate. A rotating rod is rotatably connected to the inside of the drone and above the support rod. The rotating rod is rotatably connected to the support plate. A third protective strip is sleeved on the outside of the rotating rod. The third protective strip is fixedly connected to the rotating rod. A transmission mechanism is provided between the third protective strip and the second protective strip. Under the action of the transmission mechanism, when the rotating rod drives the third protective strip to rotate, the second protective strip on each support plate will also rotate together, thereby realizing the synchronous unfolding and folding of the second and third protective strips.

[0007] Preferably, the first, second, and third protective strips are all arc-shaped structures. The arc-shaped structure prevents them from touching each other when the whole is unfolded and folded. When the two sets of first, second, and third protective strips are fully unfolded, they form a sphere, achieving the purpose of providing all-round protection for the drone.

[0008] Preferably, the transmission mechanism includes a spur gear, which is sleeved on the outside of the rotating rod and fixedly connected to the rotating rod. Movable plates are slidably connected to the outside of two adjacent rotating plates. A sliding groove is provided inside each movable plate, and a sliding rod is slidably connected inside the groove. The sliding rod is fixedly connected to the rotating plate. A rack is fixedly connected to the outside of each movable plate near the spur gear, and the rack meshes with the spur gear. When the rotating rod rotates, it drives the spur gear to rotate. The spur gear, through the rack, drives the upper and lower movable plates to move. The movable plates press the sliding rod against the inner wall of the groove, causing the sliding rod to drive the rotating plate to rotate. The rotating plate then drives the second protective strip to rotate, thus achieving the automatic unfolding and folding of the second protective strip.

[0009] Preferably, a limiting groove is formed inside the rack, and a limiting plate is slidably connected inside the limiting groove. The limiting plate is fixedly connected to the support plate. The limiting groove and the limiting plate both have a T-shaped cross-section. The outer side wall of the limiting plate fits against the inner side wall of the limiting groove. The limiting groove and the limiting plate limit the rack and the movable plate. At the same time, the T-shaped cross-section design can prevent the rack and the movable plate from detaching. A dust cover can be installed on the outside of the support plate to protect the spur gear and the rack.

[0010] Preferably, there are four rotating rods, two of which are fixedly connected, and a first connecting rod is fixedly connected between the other two rotating rods. A servo motor is fixedly connected to the bottom of the drone. The output shaft of the servo motor passes vertically through the drone and extends into the interior of the drone. The output shaft of the servo motor is rotatably connected to the drone. A first bevel gear is fixedly connected to the output end of the servo motor. A second bevel gear is sleeved on the outside of each rotating rod. The second bevel gear is fixedly connected to the rotating rod. The first bevel gear and the second bevel gear are meshed together. When the servo motor is started, it can drive the rotating rod to rotate through the first bevel gear and the second bevel gear.

[0011] Preferably, the first connecting rod is a U-shaped structure, and the four rotating rods are all on the same horizontal plane. In order to prevent collisions, the other two rotating rods on the same straight line are connected by the first connecting rod of the U-shaped structure. Since the rotating rods only need to rotate 90 degrees, the first connecting rod of the U-shaped structure will not collide with other rotating rods when rotating from one side to the other.

[0012] Preferably, a support sleeve is fitted around the rotating rod, the support sleeve is fixedly connected to the UAV, the rotating rod is rotatably connected to the support sleeve, a connecting plate is fitted around the support sleeve, the connecting plate is fixedly connected to the support sleeve, and the support rod is fixedly connected to the connecting plate. The support sleeve serves two purposes: firstly, it protects the rotating rod from debris entanglement, and secondly, it supports the rotating rod, allowing it to rotate smoothly. The connecting plate positioned between the support sleeve and the support rod further enhances the support capacity of the support rod and prevents deformation.

[0013] Preferably, a second connecting rod is fixedly connected between the support plate and the first protective strip. The first protective strip is positioned between the two outer support plates, and the second connecting rod is positioned between the first protective strip and the other two, i.e., the two inner support plates. This mainly improves the overall stability of the first protective strip. A groove is provided on one side of the third protective strip. The groove works in conjunction with the second connecting rod. When the third protective strip rotates from vertical to horizontal, the second connecting rod or rotating rod will be inside the groove, which can prevent the third protective strip from touching the second connecting rod or rotating rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1) This network-interactive long-distance land planning geographic information survey and acquisition system provides comprehensive protection and strong anti-collision capabilities during use. After the servo motor drives the transmission mechanism to activate multiple sets of protective strips, the fixed first protective strip, together with the rotatable second and third protective strips, forms a spherical protective layer. This protective layer is distributed in a star-shaped pattern in the four directions of front, back, left, and right, and in a grid pattern in the top and bottom direction. It can provide all-dimensional protection for the drone without blind spots. For various obstacles commonly found in complex terrains, such as tree branches, building corners, and high-voltage lines, this protective layer can effectively resist direct collisions between the drone and obstacles, reduce the probability of damage to the drone's fuselage, propellers, and other core components due to collisions, and significantly improve the flight safety and stability of the drone in complex operating environments.

[0015] 2) This network-interactive long-distance land planning geographic information survey and acquisition system balances protective functions with operational flexibility, highlighting its folding and storage advantages. When the drone needs to be folded and stored or flexibly traverse complex terrain, the servo motor drives in reverse. Through the linkage of transmission components such as bevel gears, flat gears, and connecting rods, the second and third protective strips rotate in opposite directions and achieve compact folding. After folding, the whole structure is a flat ring structure. This structural design can effectively reduce air resistance during drone flight, avoiding the impact of excessive protective structure volume on flight flexibility. On the other hand, it can significantly reduce the risk of drone getting entangled with obstacles such as tree branches and cables, ensuring the efficiency of drone traversing narrow spaces. At the same time, the unfolding and folding of the protective strips are completed automatically through mechanical transmission without manual intervention, ensuring both the need for comprehensive protective coverage and the operational efficiency and ease of use of the drone.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 14A network-interactive long-distance land planning geographic information survey and acquisition system includes a drone 1. The drone 1 is externally fixedly connected to four support rods 2, symmetrically distributed. Each support rod 2 has an L-shaped structure; the longer end connects to the drone 1's fuselage, and the shorter end connects to the side of a support plate 3. The support plate 3 has a disc-shaped structure. With the drone 1's fuselage as the horizontal plane, the axes of the support rods 2 and the support plate 3 are set at a 45-degree angle. This is primarily to prevent the third protective strip 8 from colliding with the support rods 2 when rotated to a horizontal position. The outer end of each support rod 2, furthest from the drone 1, is fixedly connected to the support plate 3. The four support plates 3 are divided into two groups, with opposing groups forming one group. These two groups of support plates 3 have inner and outer sections. A first protective strip 4 is positioned between the two outer support plates 3. The four outer second protective strips 6 have the same diameter as the first protective strip 4, while the third protective strips 8 are smaller. The four innermost second protective strips 6 are one ring smaller than the outermost third protective strips 8, and the innermost third protective strips 8 are one ring smaller, creating a layered effect. The support plate 3 is fixedly connected to the outside of the first protective strip 4. The support plate 3 is rotatably connected to the side of the drone 1. There are four rotating plates 5, which are symmetrically distributed. The rotating plates 5 are fixedly connected to the outside of the second protective strips 6. The drone 1 is rotatably connected to the inside of the rotating rod 2 and above the support rod 2. The rotating rod 7 is rotatably connected to the support plate 3. The rotating rod 7 is fitted with a third protective strip 8. The third protective strip 8 is fixedly connected to the rotating rod 7. A transmission mechanism 9 is set between the third protective strip 8 and the second protective strip 6. Under the action of the transmission mechanism 9, when the rotating rod 7 drives the third protective strip 8 to rotate, the second protective strip 6 on each support plate 3 will also rotate together, thereby realizing the synchronous unfolding and folding of the second protective strip 6 and the third protective strip 8.

[0020] Furthermore, the first protective strip 4, the second protective strip 6, and the third protective strip 8 are all arc-shaped structures. The arc-shaped structure ensures that they will not touch each other when the whole is unfolded and folded. When the two sets of first protective strip 4, second protective strip 6, and third protective strip 8 are fully unfolded, they form a sphere, which is a cross shape when viewed from the front, back, left, and right, and a square shape when viewed from above and below, thus achieving the purpose of providing all-round protection for the drone 1.

[0021] Furthermore, the transmission mechanism 9 includes a spur gear 10, which is sleeved on the outside of the rotating rod 7 and is fixedly connected to the rotating rod 7. A movable plate 11 is slidably connected to the outside of two adjacent rotating plates 5. A groove 12 is provided inside the movable plate 11, and a slide rod 13 is slidably connected inside the groove 12. The slide rod 13 is fixedly connected to the rotating plate 5. A rack 14 is fixedly connected to the outside of the movable plate 11 near the spur gear 10. The rack 14 meshes with the spur gear 10. When the rotating rod 7 rotates, it not only drives the third protective strip 8 to rotate but also drives the spur gear 10 to rotate. The spur gear 10 drives the upper and lower movable plates 11 to move via the rack 14. The movable plate 11 presses against the slide rod 13 through the inner wall of the groove 12, causing the slide rod 13 to drive the rotating plate 5 to rotate. The rotating plate 5 then drives the second protective strip 6 to rotate, thus achieving the automatic unfolding and folding of the second protective strip 6.

[0022] Furthermore, a limiting groove 15 is provided inside the rack 14, and a limiting plate 16 is slidably connected inside the limiting groove 15. The limiting plate 16 is fixedly connected to the support plate 3. The cross-sections of the limiting groove 15 and the limiting plate 16 are both T-shaped structures. The outer side wall of the limiting plate 16 fits against the inner side wall of the limiting groove 15. The limiting groove 15 and the limiting plate 16 limit the rack 14 and the movable plate 11, so that the rack 14 and the movable plate 11 can only move vertically. At the same time, the T-shaped cross-section design can prevent the rack 14 and the movable plate 11 from detaching. A dust cover can be installed on the outside of the support plate 3 to protect the spur gear 10 and the rack 14.

[0023] Furthermore, there are four rotating rods 7 in total. Two rotating rods 7 are fixedly connected, and a first connecting rod 20 is fixedly connected between the other two rotating rods 7. A servo motor 17 is fixedly connected to the bottom of the drone 1. The output shaft of the servo motor 17 passes vertically through the drone 1 and extends into the interior of the drone 1. The output shaft of the servo motor 17 is rotatably connected to the drone 1. A first bevel gear 18 is fixedly connected to the output end of the servo motor 17. A second bevel gear 19 is sleeved on the outside of the rotating rod 7. The second bevel gear 19 is fixedly connected to the rotating rod 7. The first bevel gear 18 and the second bevel gear 19 are meshed. When the servo motor 17 is started, it can drive the rotating rod 7 to rotate through the first bevel gear 18 and the second bevel gear 19. When the rotating rod 7 rotates, the two sets of second protective strips 6 and third protective strips 8 can be unfolded and folded.

[0024] Furthermore, the first connecting rod 20 has a U-shaped structure, and all four rotating rods 7 are on the same horizontal plane. In order to prevent collisions, the other two rotating rods 7 on the same straight line are connected by the first connecting rod 20 with the U-shaped structure. Since the rotating rods 7 only need to rotate 90 degrees, the first connecting rod 20 with the U-shaped structure will not collide with other rotating rods 7 when rotating from one side to the other, and at the same time, it ensures the normal operation of the transmission.

[0025] Furthermore, a support sleeve 21 is fitted around the rotating rod 7, the support sleeve 21 is fixedly connected to the UAV 1, the rotating rod 7 is rotatably connected to the support sleeve 21, a connecting plate 22 is fitted around the support sleeve 21, the connecting plate 22 is fixedly connected to the support sleeve 21, and the support rod 2 is fixedly connected to the connecting plate 22.

[0026] Furthermore, a second connecting rod 23 is fixedly connected between the support plate 3 and the first protective strip 4. The first protective strip 4 is located between the two support plates 3 on the outer side, and the second connecting rod 23 is located between the first protective strip 4 and the other two, that is, the two support plates 3 on the inner side. This is mainly to improve the overall stability of the first protective strip 4. A groove 24 is provided on one side of the third protective strip 8. The groove 24 is used in conjunction with the second connecting rod 23. When the third protective strip 8 is rotated from vertical to horizontal, in order to prevent the third protective strip 8 from touching the second connecting rod 23 or the rotating rod 7, a groove 24 is provided on the third protective strip 8. When the third protective strip 8 is rotated to the horizontal position, the second connecting rod 23 or the rotating rod 7 will be inside the groove 24, thereby ensuring that the third protective strip 8 can be folded into place.

[0027] The usage steps of this invention are as follows: When using this network-interactive long-distance land planning geographic information survey and acquisition system, the servo motor 17 at the bottom of the UAV 1 is started, and its output shaft drives the first bevel gear 18 to rotate. The first bevel gear 18 meshes with the second bevel gear 19 sleeved on the outside of the rotating rod 7, thereby driving the rotating rod 7 to rotate. The four rotating rods 7 are divided into two groups, and the two rotating rods 7 in the same group are connected by the first connecting rod 20 of the U-shaped structure to ensure that the rotating rods 7 in the same group rotate synchronously. Moreover, the U-shaped structure can avoid collision and interference with the other group of rotating rods 7 during rotation. The rotating rods 7 rotate At the same time, the rotating rod 7 directly drives the third protective strip 8, which is fixedly connected to it, to rotate synchronously, realizing the automatic unfolding or folding action of the third protective strip 8. While the rotating rod 7 rotates, it drives the externally fixed spur gear 10 to rotate. The spur gear 10 meshes with the rack 14 on the outside of the movable plate 11, driving the movable plate 11 to move linearly. During this process, the T-shaped limiting groove 15 and the limiting plate 16 cooperate with each other to limit the rack 14 and the movable plate 11, ensuring that they can only move in a straight line and preventing them from disengaging. When the movable plate 11 moves, the inner wall of its internal sliding groove 12 presses against the sliding rod 13 fixed to the rotating plate 5. The rotating plate 5 is driven to rotate, which in turn drives the second protective strip 6, which is fixed to it, to rotate synchronously, realizing the linkage unfolding or folding of the second protective strip 6 and the third protective strip 8. The first protective strip 4 is an arc-shaped structure fixed between the two outer support plates 3, and is connected to the inner support plate 3 through the second connecting rod 23 to ensure structural stability. When the second protective strip 6 and the third protective strip 8 are fully unfolded under the action of the transmission mechanism 9, the first protective strip 4, the second protective strip 6, and the third protective strip 8 together form a spherical protective layer. This protective layer is in a star shape in the four directions of front, back, left, and right, and in a vertical direction. The grid-shaped structure provides all-around protection for the drone 1. It can effectively resist collisions with obstacles in complex terrain, such as trees, buildings, and high-voltage lines. When it needs to be folded for storage, the servo motor 17 drives in the reverse direction, which drives the second protective strip 6 and the third protective strip 8 to rotate in the opposite direction through the above transmission path. Finally, it achieves a compact folding of the multiple layers of the second protective strip 6 and the third protective strip 8. Especially when it is necessary to flexibly navigate complex terrain, the overall flat ring structure after folding can effectively reduce flight resistance, reduce the risk of entanglement, and provide comprehensive protection coverage while taking into account operational efficiency.
