Description

Technical Field

[0001] The present invention relates to the field of geodetic surveying equipment, and specifically to a geospatial information surveying equipment and its surveying method. Background Art

[0002] Geospatial information surveying, as a key means to obtain Earth's spatial information, plays an indispensable role in many fields such as urban planning, resource exploration, environmental monitoring, and disaster warning. With the increasing requirements for the accuracy, comprehensiveness, and acquisition efficiency of geospatial information data in various industries, geodetic surveying equipment has been continuously innovating and developing.

[0003] Traditional geodetic surveying equipment has significant deficiencies in terms of stability. Common surveying equipment usually relies on a simple tripod for support. In complex terrains such as mountainous and hilly areas, it is difficult for the tripod to find a completely flat and stable support surface, and it is prone to shaking. Even on relatively flat ground, in the case of a gentle breeze, the equipment supported by the tripod will also be displaced or tilted due to wind interference, resulting in deviations in the surveying data. In some surveying tasks with extremely high accuracy requirements, such as geological surveying in the early stage of urban subway line planning, the slightest shaking of the equipment may cause the measurement results to deviate from the actual situation, thereby affecting the planning and implementation of the entire project.

[0004] The limitations of the instrument clamping method have also been plaguing the surveying industry. Most traditional equipment uses a rigid clamping device to fix surveying instruments, such as total stations and laser scanners. During the operation of this clamping method, due to the difficulty in precisely controlling the clamping force, it is extremely easy to damage the outer surface of the instrument. The optical lens part of a total station is very precise. If the clamping force is too large, it may cause the lens to be displaced or scratched, affecting the focusing and collection of light, and resulting in errors in the measured angle and distance data. Moreover, the traditional clamping device cannot flexibly adapt to surveying instruments of different sizes and shapes. For some new or special-specification instruments, additional custom-made fixtures are often required, increasing the cost and operational complexity.

[0005] The inconvenience of equipment movement has also been a long-standing problem. Traditional surveying equipment is large and bulky. When transferring the surveying location, multiple people are required to cooperate in carrying it, which is a cumbersome process and consumes a large amount of manpower and time. In remote areas in the wild, the roads are rough and vehicles are difficult to pass, and it is even more difficult to carry the equipment manually. For example, in forest resource surveying, when transferring from one observation point to another, it may be necessary to cross dense forests. Carrying the equipment not only has low efficiency but also easily causes the equipment to be damaged by collisions, seriously affecting the progress and quality of the surveying work.

[0006] The accuracy issue of equipment level calibration cannot be ignored either. Most traditional calibration methods rely on manual experience and conduct rough calibration through simple tools such as level gauges. This method is greatly affected by human factors, and there may be significant differences in the calibration results of different operators. In the preliminary surveying and mapping of some large-scale engineering construction projects, such as the cross-sea bridge, the requirement for equipment level is extremely high. Even the slightest tilt angle, after cumulative long-distance measurement, will cause a huge deviation between the final surveying and mapping data and the actual situation, posing serious potential hazards to engineering design and construction.

[0007] The comprehensiveness of surveying and mapping is also restricted by traditional equipment. Many traditional surveying and mapping equipment can only collect data within a limited angle range. To achieve full-range surveying and mapping, it is necessary to adjust the equipment position and angle multiple times, which is complex in operation and prone to missing data in some areas. In the geographical information surveying and mapping for urban 3D modeling, if the information of all angles of the city cannot be comprehensively obtained, the constructed 3D model will have data gaps and cannot truly and accurately reflect the actual situation of the city. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the present invention provides a geographical information surveying and mapping device and its surveying and mapping method, which solve the problems of unstable support, easy damage of the instrument, inconvenient movement, inaccurate calibration and incomplete surveying and mapping of traditional geographical information surveying and mapping equipment. Through innovative structural design, the stability, applicability, convenience, surveying and mapping accuracy and comprehensiveness of the equipment are improved.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: A geographical information surveying and mapping device includes a base. A rotating disk is movably installed in the middle of the top end of the base. A positioning seat is arranged above the base. Clamping blocks are movably installed on both sides of the upper surface of the positioning seat. Chute grooves are opened on both sides of the top end of the positioning seat. A cross frame is fixedly installed in the middle of the positioning seat through a bracket. Rotating frames are movably installed at both ends of the cross frame. Spring pieces are fixedly installed on both sides inside the cross frame, and the ends of the spring pieces extend into the interiors of the corresponding rotating frames on the side. Pressing rollers are fixedly installed on the inner top sides of the rotating frames, and the bottom ends of the pressing rollers are in contact with the upper surfaces of the corresponding spring pieces on the side. Swing rods are movably installed at the top ends of the rotating frames, and the ends of the swing rods are movably installed in the middle of the bottom ends of the corresponding clamping blocks on the side. A fixed rod is fixedly installed in the middle of the bottom end of the base. A movable rod is movably installed at the bottom of the fixed rod. A number of first cross rods are movably installed on the outer diameter of the fixed rod. A number of second cross rods are movably installed on the outer diameter of the movable rod. The outer ends of the corresponding second cross rods and the outer support plates are respectively movably installed on both sides of the inner ends of the outer support plates.

[0010] Preferably, lower hinge supports are fixedly installed on both sides of the top end of the rotating disk. Electric cylinders are movably installed on both sides of the top end of each lower hinge support. Upper hinge supports are fixedly installed at the four corners of the bottom end of the positioning seat. The ends of the electric cylinders are movably installed at the bottom ends of the corresponding upper hinge supports on the corresponding sides.

[0011] Preferably, a hemispherical groove is formed in the middle of the top end of the rotating disk. A hemisphere is movably arranged inside the hemispherical groove. A Mark point marker is fixedly installed on the upper surface of the hemisphere. A calibration camera is fixedly installed in the middle of the bottom end of the positioning seat.

[0012] Preferably, disks are movably installed on the front and rear sides of the upper surface of the positioning seat. Connecting rods are movably installed on both sides of the top end of each clamping block. The ends of the connecting rods are movably installed on the outer sides of the tops of the corresponding disks on the corresponding sides. Handles are fixedly installed in the middle of the top ends of the clamping blocks.

[0013] Preferably, support platforms are also movably installed on both sides inside the cross frame. A double-acting cylinder is fixedly installed in the middle of the bottom end of the cross frame. The driving ends on both sides of the double-acting cylinder are respectively fixedly installed at the bottom ends of the support platforms.

[0014] Preferably, a rotating motor is fixedly installed on one side of the base. The driving end of the rotating motor extends into the interior of the base and is fixedly installed with a driving bevel gear. A driven bevel gear is fixedly installed at the bottom end of the rotating disk, and the bottom side of the driven bevel gear is meshed and connected with the top of the driving bevel gear.

[0015] Preferably, a telescopic cylinder is fixedly installed in the middle of the bottom end of the fixed rod, and the end of the telescopic cylinder is fixedly installed at the inner bottom of the movable rod.

[0016] Preferably, universal wheels are fixedly installed at the bottom ends of the outer support plates.

[0017] A surveying method for a geographic information surveying device, characterized by comprising the following steps:

[0018] Step 1: First, start the telescopic cylinder. While the telescopic cylinder pulls the movable rod upward, it drives all the outer support plates to expand outward, and uses the expanded outer support plates to support the device.

[0019] Step 2: Pull the handle outward. By the action of the disk and the connecting rod, drive the two clamping blocks to move outward simultaneously, place the surveying instrument in the middle of the positioning seat, and after releasing the handle, use the elastic reset function of the spring piece to cooperate with the swing rod to make the clamping blocks move inward simultaneously to clamp and fix the surveying instrument.

[0020] Step 3: Use the universal wheels to move the device to the scene to be detected. When the device has an inclination angle, start the calibration camera. The calibration camera will scan the Mark points on the hemisphere. At the same time, use the coordinated expansion and contraction of the four electric cylinders to correct the angle of the positioning seat until the calibration camera completely scans the middle of the Mark points, indicating that it is in a completely horizontal state at this time;

[0021] Step 4: Start the surveying and mapping instrument to conduct surveying and mapping of geographical information. During this period, drive the active bevel gear to rotate through the rotating motor, drive the driven bevel gear and the rotating disk to rotate, and then drive the surveying and mapping equipment to rotate, realizing the all-round surveying and mapping of geographical information.

[0022] The present invention provides a geographical information surveying and mapping device and its surveying and mapping method. It has the following beneficial effects:

[0023] 1. In the present invention, the telescopic cylinder drives the movable rod to rise. By using the cooperation of the first cross rod and the second cross rod, the outer support plate is unfolded outward, providing a wider support surface for the device, significantly improving the stability during the subsequent surveying and mapping process, and reducing the measurement error caused by the device shaking.

[0024] 2. The unique structural design of the clamping block, swing rod, rotating frame and spring piece in the present invention can effectively avoid wearing the outer surface of the instrument due to excessive clamping force when clamping the surveying and mapping instrument. At the same time, the two-way cylinder can drive the support platform to change the spring piece support point, flexibly adjusting the clamping elastic force, greatly increasing the applicability to different types and sizes of surveying and mapping instruments.

[0025] 3. The cooperation of the calibration camera with the hemisphere and the Mark points in the present invention, combined with the coordinated expansion and contraction of the four electric cylinders, can quickly and accurately correct the angle of the positioning seat, ensure that the device is in a completely horizontal state, thus significantly improving the accuracy of geographical information surveying and mapping and providing a reliable data basis for subsequent data analysis.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment:

[0036] Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides a geographic information surveying and mapping device, such as Figure 1As shown in the figure, it includes a base 1. The base 1 serves as the basic support structure of the entire device, providing a platform for the installation and operation of various components above. A rotating disk 2 is movably installed in the middle of the top end of the base 1. The rotating disk 2 can rotate flexibly on the base 1, driving other components installed on it to adjust the orientation. Above the base 1, there is a positioning seat 3. The positioning seat 3 is used to accurately position the surveying instrument to ensure that the surveying instrument is in an accurate position during operation. On both sides of the upper surface of the positioning seat 3, clamping blocks 11 are movably installed. The clamping blocks 11 can move on the positioning seat 3, thereby realizing the clamping and loosening operations of the surveying instrument. On both sides of the top end of the positioning seat 3, sliding grooves 15 are opened. The clamping blocks 11 slide in the sliding grooves 15, ensuring the smoothness and accuracy of their movement. Inside the middle part of the positioning seat 3, a cross frame 16 is fixedly installed through a bracket. The cross frame 16 provides an installation foundation and support for some key components inside. At both ends of the cross frame 16, rotating frames 17 are movably installed. The rotating frames 17 can rotate around the cross frame 16, playing a key transmission role during the clamping process of the entire instrument. On both sides inside the cross frame 16, spring plates 18 are fixedly installed, and the ends of the spring plates 18 extend to the inside of the corresponding side rotating frames 17. The spring plates 18 can undergo elastic deformation under the action of the rotating frames 17, thereby generating a force to clamp or loosen the surveying instrument. Inside the inner top of the rotating frames 17, pressing rollers 19 are fixedly installed, and the bottom ends of the pressing rollers 19 are in contact with the upper surface of the corresponding side spring plates 18. As the rotating frames 17 rotate, the pressing rollers 19 can apply pressure to the spring plates 18, causing them to bend and deform. At the same time, during the deformation process of the spring plates 18, the positions of the pressing rollers 19 will also change accordingly to compensate for the change in the elastic potential energy of the spring plates 18. At the top ends of the rotating frames 17, swing rods 22 are movably installed. One end of the swing rod 22 is connected to the rotating frame 17, and the other end is connected to the clamping block 11, capable of transmitting the rotation action of the rotating frame 17 to the clamping block 11, driving the clamping block 11 to move. The ends of the swing rods 22 are movably installed in the middle of the bottom ends of the corresponding side clamping blocks 11, ensuring the stability and accuracy of the transmission. In the middle of the bottom end of the base 1, a fixed rod 26 is fixedly installed. The fixed rod 26 provides a connection foundation for the support structure below. At the bottom of the fixed rod 26, a movable rod 27 is movably installed. The movable rod 27 can move up and down at the bottom of the fixed rod 26. On the outer diameter of the fixed rod 26, a number of first cross rods 29 are movably installed. On the outer diameter of the movable rod 27, a number of second cross rods 30 are movably installed. The first cross rods 29 and the second cross rods 30 cooperate with each other. When the movable rod 27 moves up and down, the position of the outer support plate 31 can be changed. The outer ends of the corresponding side second cross rods 30 and the outer support plate 31 are respectively movably installed on both sides of the inner side end of the outer support plate 31, enabling the outer support plate 31 to expand outward or retract inward under the action of the first cross rods 29 and the second cross rods 30.

[0037] In this embodiment, lower hinge supports 4 are fixedly installed on both sides of the top end of the rotating disk 2. The lower hinge supports 4 provide connection points for the installation of the electric cylinders 6 and can ensure that the electric cylinders 6 can rotate flexibly during operation. Electric cylinders 6 are movably installed on both sides of the top end of the lower hinge supports 4. The electric cylinders 6 can provide power for the angle adjustment of the positioning seat 3 through telescopic actions. Upper hinge supports 5 are fixedly installed at the four corners of the bottom end of the positioning seat 3. The ends of the electric cylinders 6 are movably installed at the bottom ends of the corresponding upper hinge supports 5 on the corresponding sides. Through this connection method, the electric cylinders 6 can accurately control the tilt angle of the positioning seat 3, ensure that the positioning seat 3 is in a horizontal state, and improve the surveying and mapping accuracy.

[0038] Furthermore, a hemispherical groove 7 is formed in the middle of the top end of the rotating disk 2. The hemispherical groove 7 is used to place the hemisphere 8 and provides a stable placement position for the hemisphere 8. The hemisphere 8 is movably arranged inside the hemispherical groove 7. The hemisphere 8 can rotate freely within the hemispherical groove 7, and its position state can be used to reflect the level condition of the device. A mark point 9 is fixedly installed on the upper surface of the hemisphere 8. The mark point 9 serves as a calibration reference point for calibrating the camera 10. The calibration camera 10 scans it to determine whether the device is level. A calibration camera 10 is fixedly installed in the middle of the bottom end of the positioning seat 3. The calibration camera 10 can scan the mark point 9 on the hemisphere 8 and, in combination with the actions of the electric cylinders 6, realize the calibration of the levelness of the positioning seat 3.

[0039] Furthermore, disks 12 are movably installed on the front and rear sides of the upper surface of the positioning seat 3. The disks 12 can rotate on the positioning seat 3, and their rotation can drive the connecting rods 13 connected thereto to move, thereby driving the clamping blocks 11 to move. Connecting rods 13 are movably installed on both sides of the top end of the clamping blocks 11. One end of the connecting rod 13 is connected to the clamping block 11, and the other end is connected to the disk 12, which can convert the rotation of the disk 12 into the linear movement of the clamping block 11. The ends of the connecting rods 13 are movably installed on the outer sides of the top ends of the corresponding disks 12, ensuring the stability of the connection and the effectiveness of the transmission. Handles 14 are fixedly installed in the middle of the top ends of the clamping blocks 11. By holding the handles 14 and pulling, the operator can conveniently control the movement of the clamping blocks 11, thereby realizing the loading and unloading operations of the surveying instrument.

[0040] Furthermore, support platforms 20 are also movably installed on both sides inside the cross frame 16. The support platforms 20 can adjust their positions within the cross frame 16, changing the support point positions of the spring pieces 18. A double-acting cylinder 21 is fixedly installed in the middle of the bottom end of the cross frame 16. The double-acting cylinder 21 can output power to both sides simultaneously, driving the support platforms 20 to move inward or outward synchronously. The driving ends on both sides of the double-acting cylinder 21 are respectively fixedly installed at the bottom ends of the support platforms 20, ensuring that the double-acting cylinder 21 can accurately control the positions of the support platforms 20, thereby flexibly adjusting the support points of the spring pieces 18 and changing the elastic force for clamping the surveying instrument.

[0041] Further, a rotating motor 24 is fixedly installed on one side of the base 1. The rotating motor 24 provides the power source for the rotation of the entire surveying and mapping equipment. The driving end of the rotating motor 24 extends into the interior of the base 1 and is fixedly installed with a driving bevel gear 25. After the rotating motor 24 is started, it can drive the driving bevel gear 25 to rotate at a high speed. The bottom end of the rotating disk 2 is fixedly installed with a driven bevel gear 23, and one side of the bottom end of the driven bevel gear 23 is meshed with the top of the driving bevel gear 25. The rotation of the driving bevel gear 25 can drive the driven bevel gear 23 to rotate through the meshing action, and then drive components such as the rotating disk 2 and the positioning seat 3 installed on the rotating disk 2 to rotate together, realizing the all-round surveying and mapping of geographical information.

[0042] Further, a telescopic cylinder 28 is fixedly installed in the middle of the bottom end of the fixed rod 26, and the end of the telescopic cylinder 28 is fixedly installed at the inner bottom of the movable rod 27. The telescopic cylinder 28 can accurately control the up and down position of the movable rod 27 at the bottom of the fixed rod 26 through telescopic actions, so as to realize the control of the expansion or retraction of the outer support plate 31.

[0043] Further, universal wheels 32 are fixedly installed at the bottom ends of the outer support plates 31. The universal wheels 32 can enable the outer support plates 31 to drive the entire equipment to move flexibly, facilitating the transportation of the equipment to different surveying and mapping locations, reducing labor consumption and time costs.

[0044] A surveying and mapping method for a geographical information surveying and mapping equipment, characterized by comprising the following steps:

[0045] Step 1: First, start the telescopic cylinder 28. While the telescopic cylinder 28 pulls the movable rod 27 upward, it drives all the outer support plates 31 to expand outward, and uses the expanded outer support plates 31 to support the equipment.

[0046] Step 2: Pull the handle 14 outward. By the action of the disk 12 and the connecting rod 13, drive the two clamping blocks 11 to move outward simultaneously, place the surveying instrument in the middle of the positioning seat 3, and after releasing the handle 14, use the elastic reset action of the spring piece 18 to cooperate with the swing rod 22 to make the clamping blocks 11 move inward simultaneously to clamp and fix the surveying instrument.

[0047] Step 3: Use the universal wheels 32 to move the device to the scene to be detected. When the equipment has an inclination angle, start the calibration camera 10. The calibration camera 10 will scan the Mark point markings 9 on the hemisphere 8. At the same time, use the coordinated telescopic actions of the four electric cylinders 6 to correct the angle of the positioning seat 3 until the calibration camera 10 completely scans the middle of the Mark point markings 9, indicating that it is in a completely horizontal state at this time.

[0048] Step 4: Start the surveying instrument to survey geographical information. During this period, rotate the motor 24 to drive the rotation of the driving bevel gear 25, drive the driven bevel gear 23 and the rotating disk 2 to rotate, thereby driving the surveying equipment to rotate and realizing the all-round surveying of geographical information.

[0049] Working principle: First, start the telescopic cylinder 28. The telescopic cylinder 28 begins to work, and its piston moves upward, pulling the movable rod 27 upward. When the movable rod 27 rises, it will drive one end of all the second cross rods 30 to move upward accordingly. Since one end of the first cross rod 29 is installed on the fixed rod 26 and the other end is cross-connected to the second cross rod 30, with this structural cooperation, all the outer support plates 31 are driven to expand outward. The expanded outer support plates 31 form a relatively large support surface, and this support surface is used to support the equipment, significantly improving the stability of subsequent surveying and mapping, and effectively reducing the measurement errors caused by equipment shaking. Subsequently, pull one of the handles 14 outward, and the operator applies a pulling force to drive the clamp 11 at the bottom of the handle 14 to move outward. When the clamp 11 moves, the connecting rods 13 connected to both sides of its top will move together. The movement of the connecting rods 13 will drive the disk 12 connected to them to rotate. During the rotation of the disk 12, it will drive the connecting rods 13 connected to the other side to move, and then drive the clamp 11 on the other side to also move outward. Subsequently, place the instruments for surveying and mapping, such as total stations, laser scanners, etc., in the center of the positioning seat 3. At the same time, when the clamp 11 moves outward, it will drive one end of the swing rod 22 connected to it to move simultaneously, causing the other end of the swing rod 22 to press down and bend the rotating frame 17. When the rotating frame 17 rotates downward, the pressure roller 19 installed inside it will apply pressure to the spring piece 18, bending the spring piece 18. During this process, the gradually bent spring piece 18 will accumulate elastic potential energy. However, as the spring piece 18 continues to bend, the position of the pressure roller 19 inside the rotating frame 17 will also change accordingly, thereby compensating for the continuously increasing elastic potential energy of the spring piece 18. Subsequently, release the handle 14. At this time, the elastic potential energy accumulated by the spring piece 18 is released, and through the transmission of the swing rod 22, it drives the two clamps 11 to move inward simultaneously to clamp the surveying and mapping instrument. This unique clamping method ensures that the instrument is clamped without being worn on the outer surface due to excessive clamping force. In addition, the two support platforms 20 can be driven to move synchronously inward or outward by the double-acting cylinder 21. The piston of the double-acting cylinder 21 extends or retracts to both sides, pushing the support platform 20 to move, changing the support point position of the spring piece 18, and thus changing the elastic force magnitude of each clamping, greatly increasing the applicability to different types and sizes of surveying and mapping instruments. After clamping the surveying and mapping instrument, move the device to the destination to be surveyed through the universal wheels 32 installed at the bottom of the outer support plates 31. The operator pushes the equipment, and the universal wheels 32 rotate flexibly, facilitating the movement of the equipment. When the equipment has an inclination angle, start the calibration camera 10. The calibration camera 10 begins to work, scanning the mark points 9 on the hemisphere 8. At the same time, using the coordinated telescopic action of the four electric cylinders 6, the electric cylinders 6 adjust their telescopic lengths according to the information fed back by the calibration camera 10 to correct the angle of the positioning seat 3 until the calibration camera 10 completely scans the middle of the mark points 9. At this time, it indicates that the equipment is in a completely horizontal state, improving the surveying and mapping accuracy.Finally, start the surveying and mapping instrument to conduct surveying and mapping of geographical information. During this period, drive the rotation of the driving bevel gear 25 by rotating the motor 24. The rotating motor 24 is powered on and operates to drive the driving bevel gear 25 to rotate at a high speed. The rotation of the driving bevel gear 25 drives the driven bevel gear 23 and the rotating disk 2 that meshes with it to rotate, thereby driving the surveying and mapping equipment installed on the rotating disk 2 to rotate, realizing the all-round surveying and mapping of geographical information and obtaining more comprehensive and accurate geographical information data.

9. A surveying and mapping method based on the geographic information surveying and mapping device according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: First, the telescopic cylinder (28) is started, and the telescopic cylinder (28) pulls the movable rod (27) upward, while driving all the outer support plates (31) to expand outward, and the expanded outer support plates (31) are used to support the equipment; Step 2: Pull the handle (14) outwards, and use the function of the disc (12) and the connecting rod (13) to drive the two clamping blocks (11) to move outwards at the same time, and place the surveying and mapping instrument in the middle of the positioning seat (3). After releasing the handle (14), use the elastic force of the spring sheet (18) to reset, and cooperate with the swing rod (22) to make the clamping blocks (11) move inwards at the same time, so as to clamp and fix the surveying and mapping instrument; Step 3: Use the universal wheel (32) to move the device to the scene to be detected. When the device is tilted, start the calibration camera (10). The calibration camera (10) will scan the mark point mark (9) on the hemisphere (8). At the same time, use the coordinated telescopic effect of the four electric cylinders (6) to correct the angle of the positioning seat (3) until the calibration camera (10) completely scans the middle of the mark point mark (9). The surface is now in a completely horizontal state; Step 4: Start the surveying and mapping instrument to survey and map the geographic information. During this process, the active bevel gear (25) is driven to rotate by the rotating motor (24), thereby driving the driven bevel gear (23) and the rotating disk (2) to rotate, thereby driving the surveying and mapping equipment to rotate, thereby achieving a full range of surveying and mapping work on the geographic information.
