Description

Technical Field

[0001] The present invention relates to the technical field of geographic information data collection, and in particular to a surveying and mapping geographic information data collection device. Background Art

[0002] The collection of surveying and mapping geographic information data is of great significance to many aspects, including urban planning and construction, agricultural production and rural development, environmental protection and ecological restoration, national security and disaster prevention and mitigation, and the application and development of geographic big data.

[0003] In terms of environmental protection and ecological restoration, surveying and mapping geographic information data collection plays an irreplaceable role. Through surveying and mapping, risks of natural disasters such as geological disasters and floods can be discovered and warned in a timely manner, providing a scientific basis for the formulation of disaster prevention and mitigation measures. This is of great significance for protecting people's lives and property and maintaining social stability.

[0004] In terms of geographic big data applications, it is the foundation. Based on modern surveying and mapping, geographic information systems, remote sensing, satellite navigation and positioning technologies, geographic big data provides data support for various fields by collecting, storing and managing multiple types of geographic spatiotemporal big data. These data have a wide range of application scenarios in land planning, real estate allocation, environmental protection facilities, water conservancy construction, public safety, health care, tourism education and other fields.

[0005] Light reflection is a common and challenging problem in the surveying and mapping process. When light intersects with objects such as the ground and buildings, part of the light will be reflected back. This reflection phenomenon may cause distortion of the surveying and mapping data. In the case of using devices such as cameras or laser scanners to obtain geographic information, reflected light may interfere with the measurement process, resulting in uneven brightness and darkness in the image, blurred images, and the inability to accurately obtain some ground features. The surveying and mapping geographic information data acquisition device currently used is generally supported by a tripod support frame, on which instruments for collecting geographic information are installed. It is usually possible to detect whether the instrument can rotate on the tripod support frame, so as to survey different surveying and mapping points. However, for the above-mentioned light problem, it is difficult to reduce the impact of light problems on the accuracy of surveying and mapping data by adjusting the surveying and mapping instruments without moving the tripod support frame.

[0006] Therefore, the present invention proposes a surveying and mapping geographic information data acquisition device to reduce the impact of light changes (such as light intensity, light angle, etc.) on surveying and mapping accuracy. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a surveying and mapping geographic information data acquisition device to reduce the impact of light changes (such as light intensity, light angle, etc.) on surveying and mapping accuracy.

[0008] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a surveying and mapping geographic information data acquisition device, including a tripod support frame and a surveying and mapping data acquisition instrument, a lifting component for adjusting the height of the surveying and mapping data acquisition instrument is installed on the top of the tripod support frame, a rotating seat is fixedly connected to the top of the lifting component, a guide plate is fixedly connected to the top of the rotating seat, a guide groove is opened on the top of the guide plate, the guide groove is slidably matched with a sliding component for changing the plane coordinates of the surveying and mapping data acquisition instrument, and the surveying and mapping data acquisition instrument is rotatably connected inside the sliding component.

[0009] Principle of the basic solution: The horizontal height of the surveying and mapping data collector is adjusted through the lifting assembly to meet the height adjustment requirements during geographic surveying and mapping, and the guide plate is able to rotate 360° using the rotating seat. The sliding assembly can then be moved to any position within the set plane through the guide groove on the guide plate. By adjusting the position of the surveying and mapping data collector, a position with better light conditions can be selected for data collection, thereby improving the collection accuracy of surveying and mapping geographic data.

[0010] The above scheme has the following beneficial effects:

[0011] 1. Compared with the existing technology, this solution integrates multifunctional components such as a tripod support frame, a lifting assembly, a rotating seat, a guide plate and a sliding assembly. After the tripod support frame is fixed, the surveying and mapping data acquisition instrument can be flexibly adjusted in three-dimensional space without moving the entire device, so that workers can adjust the specific position of the surveying and mapping data acquisition instrument according to actual conditions (light changes), which not only improves the flexibility of data collection, but also can meet the surveying and mapping needs in different geographical environments, and significantly improve the efficiency and accuracy of surveying and mapping operations.

[0012] 2. In this solution, the lifting assembly can accurately adjust the height of the surveying and mapping data collector to ensure that stable and accurate data can be obtained under different terrain conditions. At the same time, the 360° rotation function of the rotating seat enables the surveying and mapping data collector to cover the target area in all directions, avoiding surveying and mapping blind spots caused by angle limitations, so that workers can quickly complete the surveying and mapping data collection of a certain area. The cooperation between the guide groove and the sliding assembly further enhances the flexibility of the device, allowing surveyors to easily move the surveying and mapping data collector to the desired position (within the range of the device) to select a suitable position for surveying and mapping data collection, reduce the impact of light problems on surveying and mapping data, and obtain more accurate and comprehensive geographic information data.

[0013] Furthermore, the lifting assembly includes an adjusting rod threadedly connected to the triangular support frame, and the top of the adjusting rod is fixedly connected to the bottom of the rotating seat.

[0014] Beneficial effect: By rotating the adjustment rod, the height of the rotating seat and the surveying and mapping data acquisition instrument above it can be accurately adjusted. Since the adjustment rod and the tripod support frame are connected by threads, this mechanical adjustment method has stability and reliability, and can ensure the precise positioning of the surveying and mapping data acquisition instrument in the vertical direction.

[0015] Furthermore, the sliding assembly includes a concave support frame, a sliding base is fixedly connected to the bottom of the concave support frame, and a first roller and a second roller are respectively arranged on both sides of the sliding base, and the outer edges of the first roller and the second roller are in contact with the two side walls of the guide groove; the two inner side walls of the concave support frame are symmetrically rotatably connected with stabilizing shafts, and the stabilizing shafts are rotatably connected to the two side walls in the width direction of the surveying and mapping data acquisition instrument at one end close to each other and the connection points are close to the top of the surveying and mapping data acquisition instrument; the second roller is coaxially fixedly connected with a transmission assembly, and the transmission assembly is threadedly connected with a shading assembly.

[0016] Beneficial effects: The design of the first roller and the second roller enables the sliding assembly to move smoothly along the guide groove, reducing friction and resistance, improving the smoothness and stability of movement, helping to ensure that the surveying and mapping data acquisition instrument remains stable during movement, and can quickly complete the movement, reducing surveying and mapping errors caused by shaking or bumps.

[0017] The surveying and mapping data collector is rotationally connected to the concave support frame through a stabilizing axis, so that the surveying and mapping data collector can better maintain its posture stability during movement, which helps to prevent the surveying and mapping data collector from tilting or flipping due to external forces, thereby ensuring the accuracy of the surveying and mapping data.

[0018] Furthermore, the shading assembly includes a first shading plate threadedly connected to the transmission assembly, and sliding grooves are symmetrically opened on the top of the concave support frame. Both ends of the first shading plate in the width direction are respectively slidably matched with the two sliding grooves.

[0019] Beneficial effect: When the second roller rotates, the design of the first shading plate and the transmission assembly enables the surveying and mapping personnel to drive the movement of the transmission assembly in the process of moving the concave support frame, thereby causing the first shading plate to slide along the sliding groove, adjusting the position of the first shading plate, and performing adaptive adjustment, thereby performing preliminary shading processing on the surveying and mapping data acquisition instrument, so that the light conditions are kept within a suitable working range, so as to reduce light interference and improve the accuracy of the surveying and mapping data.

[0020] Furthermore, an arc-shaped through groove is opened on the outer surface of the concave support frame near one end of the first roller, and the center of the arc-shaped through groove is located on the central axis of the stabilizing shaft; a limit rod is fixedly connected to the side of the surveying and mapping data acquisition instrument near the arc-shaped through groove, and the limit rod passes through the arc-shaped through groove at one end away from the surveying and mapping data acquisition instrument and is threadedly connected with a locking nut; the diameter of the limit rod is smaller than the width of the arc-shaped through groove.

[0021] Beneficial effects: The combined design of the arc-shaped slot and the limit rod enables the surveying and mapping data collector to maintain stable support and positioning when rotating around the stable axis to adjust the angle. At the same time, since the limit rod can move freely along the arc-shaped slot, the surveying and mapping data collector can flexibly adjust the tilt angle within a certain range to adapt to different surveying and mapping needs and environmental conditions, further reduce the possibility of light interference, and improve the flexibility of the device.

[0022] By rotating the locking nut, the position of the limit rod in the arc-shaped through slot can be accurately fixed, thereby fixing the angle of the surveying and mapping data collector. This allows surveyors to easily adjust the surveying and mapping data collector to the required angle according to the requirements of the surveying and mapping task, and ensure that it remains stable during the surveying and mapping process, which helps to improve the accuracy and reliability of the surveying and mapping data.

[0023] The gear train is a gear that is engaged with the first and second gears and is engaged with the gear of the gear train. The gear train is a gear that is engaged with the gear of the gear train and is interlocked with the gear of the gear train. The gear train is a gear that is engaged with the gear of the gear train and is interlocked with the gear of the gear train.

[0024] Beneficial effects: The power is transmitted through the meshing of the bevel gear set, and the power of the second roller during rotation is transferred to the threaded rod. The rotation of the threaded rod drives the first shading plate to slide along the sliding groove. At the same time, the multi-stage bevel gear transmission is adopted to realize the association between the sliding of the concave support frame and the sliding of the first shading plate, so that the position of the first shading plate is fine-tuned through the movement of the concave support frame, thereby improving the accuracy of the shading adjustment, so as to improve the accuracy of the surveying and mapping geographic data. Through a series of transmission designs, the concave support frame and the first shading plate are linked, and the position of the first shading plate can be adjusted synchronously while the concave support frame is moved, and the surveying and mapping data acquisition instrument is subjected to preliminary shading treatment, thereby reducing light interference and improving the accuracy of the surveying and mapping data. Through the linkage design, the surveying and mapping personnel can flexibly adjust the shading range and angle of the shading component according to the actual light conditions, which not only improves the flexibility of the surveying and mapping work, but also enables the shading component to better adapt to different surveying and mapping environments and light conditions. It can also help to maintain the stability of the surveying and mapping data acquisition instrument during movement and prevent surveying and mapping errors caused by light changes or external forces. The linkage design enables the shading component to respond quickly to light changes and adjust the shading range in time, thereby ensuring the continuity and accuracy of surveying and mapping data collection.

[0025] Furthermore, the guide plate and the guide groove are both arc-shaped structures.

[0026] Beneficial effects: The guide plate and guide groove of the arc structure can better fit the moving track of the sliding component (such as the first shading plate or other mapping components), reduce the shaking and deviation of the concave support frame during the movement, thereby enhancing the stability of the guide and ensuring that the mapping component can accurately and smoothly move along the predetermined path. At the same time, the design of the arc structure can also ensure that when the guide plate does not rotate, the concave support frame is moved, and the mapping data acquisition instrument therein is always aligned with the center of the guide plate, that is, always aligned with the area where data needs to be collected, avoiding the problem of re-adjustment.

[0027] Furthermore, the shading assembly also includes a second shading plate arranged at the bottom of the first shading plate, and the first shading plate is slidably matched with the second shading plate.

[0028] Beneficial effects: The combined use of the first shading plate and the second shading plate can form a more rigorous shading structure. By adjusting the relative position between the first shading plate and the second shading plate, effective shielding of light of different angles and intensities can be achieved, thereby improving the shading effect and reducing the interference of light on the surveying and mapping data acquisition instrument. The sliding fit design between the first shading plate and the second shading plate allows surveying and mapping personnel to flexibly adjust the shading range and angle of the shading assembly according to actual surveying and mapping needs, which not only improves the flexibility of surveying and mapping work, but also enables the shading assembly to better adapt to different surveying and mapping environments and light conditions, and better cooperate with the movement of the concave support frame to select the position.

[0029] Furthermore, both inner side walls of the guide groove, the outer surface of the first roller and the outer surface of the second roller are bonded with anti-slip layers.

[0030] Beneficial effect: The presence of the anti-slip layer increases the friction between the guide groove and the sliding components (such as the first roller, the second roller and other components connected thereto), helping to ensure that the first roller and the second roller are stable rollers in the guide groove, reducing the possibility of the second roller slipping, thereby ensuring that the movement of the second roller can be stably transmitted to the threaded rod, causing the first shading plate to slide, thereby improving the stability and accuracy of the entire surveying and mapping geographic information data acquisition device.

[0031] Furthermore, a second anti-slip layer is provided on one side of the concave support frame close to the locking nut.

[0032] Beneficial effect: The second anti-skid layer can increase the friction between the concave support frame and the locking nut, ensuring that the locking nut can be firmly fixed on the concave support frame after tightening, and helping to prevent the locking nut from loosening under vibration or external force, thereby ensuring that the angle adjustment of the surveying and mapping data acquisition instrument remains accurate and stable. And by adding the second anti-skid layer, the connection between the concave support frame and the locking nut becomes more firm and stable, which helps to improve the structural strength and stability of the entire surveying and mapping geographic information data acquisition device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The following is further described in detail through specific implementation methods:

[0043] Embodiment 1:

[0044] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: a surveying and mapping geographic information data acquisition device, including a tripod support frame 1 and a surveying and mapping data acquisition instrument 6, a lifting component for adjusting the height of the surveying and mapping data acquisition instrument 6 is installed on the top of the tripod support frame 1, a rotating seat 12 is fixedly connected to the top of the lifting component, a guide plate 2 is screwed fixedly connected to the top of the rotating seat 12, a guide groove is opened on the top of the guide plate 2, the guide plate 2 and the guide groove are both arc structures, the guide groove is slidably matched with a sliding component for changing the plane coordinates of the surveying and mapping data acquisition instrument 6, the guide plate 2 and the guide groove with an arc structure can better fit the moving trajectory of the sliding component, reduce the shaking and deviation of the sliding component during the movement, thereby enhancing the stability of the guide, and ensuring that the surveying and mapping component can accurately and smoothly move along the predetermined path.

[0045] The lifting assembly includes an adjusting rod 13 threadedly connected to the tripod support frame 1 , and the top of the adjusting rod 13 is fixedly connected with the bottom of the rotating seat 12 by bolts.

[0046] The sliding assembly includes a concave support frame 3, a sliding base 14 is integrally formed at the bottom of the concave support frame 3, and a first roller 15 and a second roller 16 are respectively arranged on both sides of the sliding base 14, and the outer edges of the first roller 15 and the second roller 16 are in contact with the two side walls of the guide groove; the two inner side walls of the concave support frame 3 are symmetrically connected to the stabilizing shaft 10 for rotation, and the stabilizing shaft 10 is rotationally connected to the two side walls of the surveying and mapping data acquisition instrument 6 in the width direction at one end close to each other, and the connection points are close to the top of the surveying and mapping data acquisition instrument 6; the second roller 16 is coaxially fixedly connected to the transmission assembly, and the transmission assembly is threadedly connected to the shading assembly.

[0047] The shading assembly includes a first shading plate 5 threadedly connected to the transmission assembly, and a sliding groove 4 is symmetrically opened at the top of the concave support frame 3. The two ends of the first shading plate 5 in the width direction are respectively slidably matched with the two sliding grooves 4. In addition, when collecting surveying and mapping geographic data, if the weather is good (i.e., the light conditions are good), there is no need to perform shading treatment, so that the middle part of the first shading plate 5 and the part located in the sliding groove are detachably connected (in the form of a buckle / slot) to be installed and uninstalled according to actual conditions, thereby further improving the adaptability of the device and not affecting data collection in normal light. At the same time, shading treatment can also be performed when the reflected light is strong.

[0048] The transmission assembly includes a first rotating shaft 17 coaxially screwed and fixedly connected with the second roller 16. The top end of the first rotating shaft 17 passes through the sliding base 14 and extends to the inside of the concave support frame 3 and is coaxially keyed to a first bevel gear 18 ( Figure 4 ), the first bevel gear 18 is meshed with the second bevel gear 19, the second bevel gear 19 is coaxially keyed to the second rotating shaft 20, and the right end of the second rotating shaft 20 is coaxially keyed to the third bevel gear 21 ( Figure 4), the third bevel gear 21 is meshed with the fourth bevel gear 22, the fourth bevel gear 22 is coaxially keyed to the third rotating shaft 23, and the top of the third rotating shaft 23 is coaxially fixedly connected to the fifth bevel gear 24 ( Figure 4 ), the fifth bevel gear 24 is meshed with the sixth bevel gear 25, and the sixth bevel gear 25 is coaxially fixedly connected with a threaded rod 26 located in the sliding groove 4 near one end of the second roller 16; the concave support frame 3 and the sliding base 14 are both rotatably matched with the first rotating shaft 17; the second rotating shaft 20, the third rotating shaft 23 and the threaded rod 26 are all rotatably matched with the concave support frame 3.

[0049] The specific implementation process is as follows: first, the tripod support frame 1 is stably placed on the ground or on the geographical location to be surveyed, and then the height of the rotating base 12 and all the components above it are adjusted by rotating the adjustment rod 13. Under normal light conditions, it is only necessary to rotate the arc-shaped guide plate 2 to align the surveying and mapping data collector 6 with the area to be collected, and then collect the surveying and mapping geographic data.

[0050] When the reflected light entering the surveying and mapping data acquisition instrument 6 is strong, the concave side of the guide plate 2 is first aligned with the data acquisition area (the surveying and mapping data acquisition instrument 6 is always aligned with the center of the guide plate 2, that is, it is always aligned with the area where data needs to be collected), and then the concave support frame 3 is pushed to move along the guide groove on the guide plate 2. Since the outer edges of the first roller 15 and the second roller 16 are in contact with the inner wall of the guide groove, the first roller 15 and the second roller 16 are rotated by friction; when the second roller 16 rotates, it will drive the first rotating shaft 17 to rotate, and the first rotating shaft 17 will drive the first bevel gear 18 to rotate and drive the second bevel gear 19 meshing with the first bevel gear 18, and then the second bevel gear 19 will drive the second rotating shaft 20 to rotate and the second rotating shaft 20 will drive the third bevel gear 21, and then the third bevel gear 21 will drive the fourth bevel gear 22, and then the fourth bevel gear 22 will drive The third rotating shaft 23 is driven, and the third rotating shaft 23 drives the fifth bevel gear 24, and then the fifth bevel gear 24 drives the sixth bevel gear 25, so that the threaded rod 26 is driven to rotate through the sixth bevel gear 25. Since both sides of the first light shielding plate 5 in the width direction are slidably matched with the sliding groove 4 (slider sliding groove method), the movement direction and method of the first light shielding plate 5 are limited, so that the threaded rod 26 and the first light shielding plate 5 form a ball screw structure, and then the rotation of the threaded rod 26 is converted into the sliding of the first light shielding plate 5, so as to realize the association between the movement of the first light shielding plate 5 and the movement of the concave support frame 3, so that the first light shielding plate 5 is fine-tuned synchronously by moving the concave support frame 3, so as to quickly adjust the intensity of the reflected light entering the surveying and mapping data acquisition instrument 6, so that it reaches a reasonable range for surveying and mapping data acquisition, so as to reduce the influence of light changes (such as light intensity, light angle, etc.) on the surveying and mapping accuracy.

[0051] Embodiment 2:

[0052] The difference from Example 1 is that Figure 1 , Figure 2 and Figure 3 As shown, an arc-shaped through groove 7 is formed on the outer surface of the concave support frame 3 near the end of the first roller 15, and the center of the arc-shaped through groove 7 is located on the central axis of the stabilizing shaft 10; a limit rod 9 is fixedly connected to the side of the surveying and mapping data acquisition instrument 6 near the arc-shaped through groove 7, and the limit rod 9 passes through the arc-shaped through groove 7 at the end away from the surveying and mapping data acquisition instrument 6 and is threadedly connected with a locking nut 8; the diameter of the limit rod 9 is smaller than the width of the arc-shaped through groove 7. When the angle of the surveying and mapping data acquisition instrument 6 needs to be adjusted, the staff can push the limit rod 9 to slide in the arc-shaped through groove 7 to adjust the angle of the surveying and mapping data acquisition instrument 6 in real time, thereby finding a better angle for surveying and mapping data acquisition and improving the accuracy of the collected surveying and mapping data.

[0053] Embodiment 3:

[0054] The difference from Example 2 is that, since the movement range of the first shading plate 5 is limited, that is, its shading effect is limited, when the ambient light conditions for data collection are poor (the reflected light intensity is high), it may happen that no matter how the concave support frame 3 and the first shading plate 5 are moved, the light conditions entering the surveying and mapping data acquisition instrument 6 cannot reach an appropriate range, so the shading assembly also includes a second shading plate 11 arranged at the bottom of the first shading plate 5, and the first shading plate 5 and the second shading plate 11 are slidably matched. The second shading plate 11 increases the overall shading adjustment range of the device. When the first shading plate 5 cannot meet the light intake requirements of the surveying and mapping data acquisition instrument 6, the second shading plate 11 can be manually slid, and the first shading plate 5 and the second shading plate 11 work together to meet the light intake requirements of the surveying and mapping data acquisition instrument 6, thereby improving the accuracy of the collection of surveying and mapping geographic information data and reducing the impact of light changes on surveying and mapping accuracy.

[0055] Embodiment 4:

[0056] The difference from Example 3 is that when the second roller 16 moves in the guide groove, if the friction between the second roller 16 and the inner wall of the guide groove is insufficient, the second roller 16 will slide relative to the inner wall of the guide groove instead of rolling, making it difficult to effectively rotate the second roller 16 to drive the first rotating shaft 17, and further difficult to effectively drive the threaded rod 26 to rotate through a series of transmissions, and difficult to synchronize the movements of the concave support frame 3 and the first shading plate 5, thereby reducing the efficiency of shading adjustment. Therefore, the first anti-slip layer is bonded to the two inner walls of the guide groove, the outer surface of the first roller 15 and the outer surface of the second roller 16, thereby increasing the friction between the second roller 16 and the inner wall of the guide groove and reducing the possibility of sliding.

[0057] At the same time, when the angle of the concave support frame 3 is fixed by the locking nut 8, a second anti-slip layer is provided on the side of the concave support frame 3 close to the locking nut 8, which increases the friction coefficient when the locking nut 8 contacts the concave support frame 3, so that the worker can rotate the locking nut 8 more easily and quickly, and there is no need to excessively squeeze the locking nut 8 and the concave support frame 3, so that the angle of the concave support frame 3 can be fixed, so that the worker can adjust the angle of the surveying and mapping data acquisition instrument 6 by turning the locking nut 8 to suit the actual situation.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
