Description

Technical Field

[0001] This invention belongs to the field of topographic surveying technology, and more specifically, relates to a multidimensional measurement device and method for land spatial planning topographic surveying. Background Technology

[0002] Territorial spatial planning aims to integrate various spatial resources, optimize urban and rural layout, and achieve efficient land resource utilization and coordinated development of the ecological environment. To ensure the scientific rigor, rationality, and feasibility of the planning, topographic surveying devices are often required. These devices can effectively measure basic data such as elevation and horizontal position, producing detailed and accurate topographic maps that help planners intuitively understand the terrain. However, traditional topographic surveying devices typically employ simple measurement methods, often only capable of single-dimensional measurements. They determine horizontal coordinates and elevation by measuring angles and distances. When considering key factors such as terrain undulations, surface feature distribution, underground geological structures, and pipeline layouts, traditional devices cannot perform multi-dimensional measurements. This results in topographic data severely lacking crucial information, making it difficult to comprehensively represent the entire terrain. Consequently, planning schemes lack feasibility when encountering complex terrain and underground conditions, impacting the scientific rigor and rationality of territorial spatial planning.

[0012] According to an effective embodiment, a workbench is provided on the base, a second electric cylinder is provided on the workbench, and a marker is provided below the workbench. The shaft end of the second electric cylinder passes through the workbench and is connected to the marker. The marker is cross-shaped and has a blade-like bottom.

The multiple sets of liquid inlet pipes are connected by a first connecting pipe, and the multiple sets of liquid inlet chambers are interconnected. The water pump is connected to the first connecting pipe and the liquid storage tank through a second connecting pipe.

[0013] A measurement method, employing the aforementioned multidimensional measurement land spatial planning topographic surveying device, includes the following steps: Step 1: Equipment placement and basic commissioning; Move the device to the measurement position and use multiple sets of fixing components on the base to fix the entire device and ensure its stability. After the device is fixed, the level detector at the bottom of the support platform is activated to effectively detect the levelness of the device. When measuring in more complex terrain, the device may tilt. The level detector will detect that the device is not level and activate multiple sets of first electric cylinders. The first electric cylinders are connected to the support platform through connectors to adjust the height of the support platform. The device will stop after the level detector reports that the support platform is in a level state. Step 2: Install the moving components and the 3D laser scanner; The moving component is connected to the lifting component via a locking component. The locking base and locking block cooperate with the positioning bolt, spring, and locking bolt to securely lock the connecting block at the bottom of the mounting frame into the locking slot, thus installing the moving component. At the same time, the position of the mounting frame is adjusted by turning the adjusting bolt according to measurement requirements. A connecting frame can also be selected as needed. When a connecting frame is required, it is installed at the preset connection positions on both sides of the mounting frame, located at one end of the mounting plate, so that the first slide rail on the mounting plate and the second slide rail on the connecting frame are in contact with each other to form a moving slide rail. One end of the first hydraulic rod at the bottom of the connecting frame is connected to the mounting frame via a pin, forming a triangular structure. Step 3: 3D laser scanner measurement and underground exploration; Based on the measurement area, the electric slider is controlled to move along a sliding rail, which consists of a first rail and a second rail. When the connecting frame is not used, the photoelectric sensor on the first rail is activated and maintains monitoring, allowing the electric slider to move only within the first moving area. When the connecting frame is used, one end of the second rail contacts the first rail, pressing a pressure sensor at one end of the first rail. The pressure sensor sends a signal, causing the photoelectric sensor to monitor the electric slider, allowing it to move between the first and second moving areas. Based on the characteristics of the measured object, the controller activates and sets various parameters of the 3D laser scanner. Simultaneously, the rotary motor is activated, and the rotation stage angle is adjusted, enabling the 3D laser scanner to perform multi-directional scanning and transmit the scanned data to the controller. The controller also activates the ground-penetrating radar, setting its transmission frequency and pulse width parameters. The ground-penetrating radar then detects underground structures, acquires information about the underground structure, and transmits it to the controller. Step 4: Activate the measurement component and acquire data; Activate the lifting assembly to unfold the arc-shaped slide rails, forming a ring between the two sets of arc-shaped slide rails. The electromagnet contacts the magnetic plate and activates the electromagnet to fix the arc-shaped slide rails in place. When the arc-shaped slide rails are folded, the electric pulleys are located in the storage area. When the arc-shaped slide rails are unfolded, the electric pulleys move to the working area. Activate the electric pulleys to move the optical camera along the arc-shaped slide rails, collect surrounding image data, and transmit the collected data to the controller. Step 5: Environmental adjustment to ensure equipment operation; During use, the air pump is activated according to the temperature. By controlling the two sets of solenoid valves on the first conduit, air can be drawn from either the cold air box or the heating box. The cold air box cools the gas, thereby cooling the 3D laser scanner and optical camera; the heating box heats the gas, removing water mist and frost from the lenses of the 3D laser scanner and optical camera when used in low-temperature environments. Step Six: Data Processing and Record Tagging; After the measurement is completed, the collected data is transmitted to the controller for processing. If the measurement area needs to be marked, the second electric cylinder of the workbench is activated to push the marker down, and the blade-shaped part of the marker is removed into the soil. The water pump is activated to spray the marking liquid in the storage tank through the inlet pipe and inlet chamber and out of the outlet hole to form a mark on the ground.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This device integrates a 3D laser scanner, ground-penetrating radar, and measurement components. The 3D laser scanner, through the cooperation of the electric slider, rotating table, and rotating motor of the moving component, can scan the terrain surface from multiple angles and in all directions to obtain the 3D coordinate information of the terrain. At the same time, the ground-penetrating radar can detect underground structures and provide information on underground space. The electric pulley of the measurement component drives the optical camera to move along the arc-shaped slide rail to collect surrounding image data. This data is then fused with the 3D laser scanning and ground-penetrating radar data to achieve multi-dimensional terrain measurement, providing comprehensive and accurate data support for land spatial planning and improving the scientificity and feasibility of planning schemes.

[0015] 2. The mobile assembly includes a cold air box and a heating box mounted on the mounting frame. These effectively ensure stable operation of the equipment under varying ambient temperatures. In high-temperature environments, the air pump and cold air box are activated. The first fan draws outside air into the first chamber, which then enters the second chamber through the vents in the partition block. Due to the funnel-shaped design of the vents, the airflow is accelerated and the temperature is reduced. The air is then blown out through the air outlet of the air ring via the air pump and the second duct, cooling the 3D laser scanner and preventing high temperatures from affecting the equipment's performance and accuracy. In low-temperature environments, the second fan in the heating box blows outside air towards the heating wires. The heated air then defrosts and defoams the equipment through the same path, ensuring normal operation and extending its service life.

[0016] 3. The worktable at the base of the device is equipped with a marking function, which can leave clear marks in the measurement area. When marking is needed, the second electric cylinder is activated to push the marker down, its blade-shaped bottom inserting into the soil, and the second hydraulic rod makes the mark more stable. At the same time, the water pump is activated, and the marking liquid in the storage tank is sprayed out from the outlet through the inlet pipe and inlet chamber, forming a clear mark on the ground. This marking function allows surveyors to quickly locate measurement points, and in subsequent measurements, reviews, or planning implementation, it can accurately find the corresponding location, improve work efficiency, reduce errors caused by inaccurate positioning, and provide convenience for land spatial planning work.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0020] Example 1: As Figures 1 to 19As shown, this invention provides a multi-dimensional measurement device for land spatial planning topographic surveying, including a base 11. The base 11 serves as a basic support, providing the foundation for the stable placement of the entire device. Multiple sets of first electric cylinders 31 are mounted vertically on the base 11. The shaft ends of the first electric cylinders 31 are connected to a support platform 32 via connectors. The height of the support platform 32 can be adjusted by the telescopic operation of the first electric cylinders 31. The connectors are common universal joint structures, allowing the first electric cylinders 31 to adapt to different angle changes of the support platform 32, ensuring smooth raising and lowering of the support platform 32 even under complex terrain conditions. A level detector 23 is installed at the bottom of the support platform 32, acting like a meticulous inspector, monitoring the level of the support platform 32 in real time. Once a tilt is detected, the information is quickly fed back to the control system, and the first electric cylinders 31 respond immediately, precisely adjusting the height of the support platform 32 to ensure the entire device is always in the optimal working posture, providing a stable and reliable platform for subsequent measurement work. A level detector 23 is installed at the bottom of the support platform 32. Its main function is to monitor whether the support platform 32 is level in real time, and it works in conjunction with the multiple sets of first electric cylinders 31. When the level detector 23 detects that the support platform 32 is tilted, it will immediately transmit a signal to the control unit. After receiving the signal, the control unit quickly calculates and sends a command to the first electric cylinders 31, causing the first electric cylinders 31 to adjust the angle of the support platform 32 through extension and retraction adjustment until the level detector 23 reports that the support platform 32 is level, ensuring the stable operation of the entire measuring device. The level detector 23 can be a Leica NA2 level. A lifting assembly and a moving assembly are provided above the support platform 32. The bottom of the lifting assembly is detachably connected to the support platform 32, and multiple sets of locking assemblies are provided on its top. These locking assemblies include locking bases 401 and locking blocks 402, etc. The moving component is securely connected to the lifting component through the cooperation of the positioning bolt 405, spring, and locking bolt 406. The 3D laser scanner 21 is mounted on the rotating platform 507 on the moving plate 503 within the moving component. A rotating motor drives the rotating platform 507 to rotate, coordinating with the movement of the moving plate 503 along the moving slide rail. The moving slide rail consists of a first slide rail 504 on the mounting plate 409 and a second slide rail 505 on the connecting frame 410, enabling scanning of terrain at different angles and positions. The 3D laser scanner 21 can be a FAROFocus S70 3D laser scanner. Simultaneously, the height of the moving component can be adjusted according to usage requirements via the lifting component, thereby adjusting the height of the 3D laser scanner 21. When scanning targets at higher elevations, the lifting component activates, slowly raising the moving component to a suitable height for the 3D laser scanner 21. For measurements in low-lying areas, the lifting component operates in reverse, lowering the scanner height to meet measurement needs in different scenarios, thus improving the flexibility and applicability of measurements.A measuring component is arranged between the support platform 32 and the moving component, and the measuring component is connected to the lifting component. This measuring component includes multiple sets of arc-shaped slide rails 601, etc. The connecting plate 603 on the inner side of the arc-shaped slide rails 601 is rotatably connected to the mounting bracket 602. An electric pulley 611 drives an optical camera 612 to move on the arc-shaped slide rails 601 to collect image data. The optical camera 612 can be a Basler acA2500-14gm optical camera. A ground-penetrating radar 22 is installed at the bottom of the support platform 32. The base 11 has a through slot corresponding to the ground-penetrating radar 22, facilitating its detection of underground structures. The ground-penetrating radar 22 can be a GSSI SIR-4000 ground-penetrating radar. A controller is also located above the support platform 32 to control the operation of each component. The controller can be an Advantech ARK-3520 controller. The battery module on the base 11 powers the entire device. The device can be used with a fixing component to ensure that it is fixed to the ground during operation, avoiding unnecessary shaking.

[0021] like Figures 2 to 5 , Figure 15As shown, the locking assembly includes a locking base 401 and a locking block 402. A protruding locking block 403 is provided on one side of the locking base 401, and a locking groove 404 is formed on the other side. During installation, the bottom of the locking block 402 is inserted into the locking groove 404, initially establishing a connection between the two. Multiple sets of positioning holes are distributed on both the locking block 402 and the locking base 401, and positioning bolts 405 are sequentially inserted into these positioning holes. Here, the length of the positioning bolts 405 is greater than the depth of the locking groove 404, allowing the locking block 402 to slide within a certain range with the locking base 401 via the positioning bolts 405. Multiple sets of springs are also provided between the two, all of which are sleeved on the positioning bolts 405. When disassembling the moving assembly, rotating the locking bolt 406 releases its locking of the locking block 402 and the locking base 401. At this point, due to the elasticity of the spring, the previously compressed spring instantly recovers its deformation, generating an outward thrust, causing the locking block 402 to automatically open and separate from the locking base 401. This simplifies the disassembly process of the moving component and improves operational efficiency. Furthermore, locking holes are provided on the locking base 401 and the locking block 402, through which the locking bolt 406 passes. A rotating nut is fitted onto one end of the locking bolt 406. When further securing of the locking block 402 and the locking base 401 is required, simply rotating the nut will make the connection more secure. Ultimately, a locking groove is formed between the locking block 402 and the locking block 403, and the connecting block 502 of the moving component can be securely locked within this groove, ensuring the stability of the entire device during operation. The locking assembly enables rapid disassembly of the moving component. When disassembly is required, simply unscrew the rotating nut at one end of the locking bolt 406, pull out the locking bolt 406, and the spring fitted on the positioning bolt 405 will take effect, pushing the locking block 402 out of the locking groove 404 of the locking base 401, so that the moving component is separated from other parts. The operation is simple and convenient, and can save a lot of disassembly time.

[0022] The movable component includes a mounting bracket 501. Multiple connecting blocks 502 are provided at the bottom of the mounting bracket 501. These connecting blocks 502 can be engaged in locking slots formed by the locking base 401 and the locking blocks 402, thereby connecting with the locking component. Multiple adjusting holes 407 are provided on the locking base 401. An adjusting bolt 408 can pass through one of the adjusting holes 407, and one end of the connecting block 502 contacts the adjusting bolt 408. When the position of the mounting bracket 501 needs to be adjusted, simply rotating the adjusting bolt 408 will push the connecting block 502 to make a fine adjustment, thus adjusting the position of the mounting bracket 501. The mounting bracket 501 also has multiple mounting plates 409, and connecting brackets 410 are installed on both sides of the mounting bracket 501. The connecting brackets 410 and the multiple mounting plates 409 are detachably connected, facilitating component replacement or adjustment under different measurement requirements. A first hydraulic rod 411 is provided below the connecting frame 410. One end of the first hydraulic rod 411 is rotatably connected to the connecting frame 410 via a movable joint, and the other end is detachably connected to the mounting frame 501 via a pin. The connecting frame 410, the mounting frame 501, and the first hydraulic rod 411 naturally form a triangular structure. This triangular structure enhances the stability of the moving components and ensures reliable operation under various measurement environments.

[0023] The moving assembly also includes a moving plate 503. A first slide rail 504 is mounted on the mounting plate 409, while multiple sets of second slide rails 505 are provided on the connecting frame 410. The two ends of the first slide rail 504 respectively contact the two sets of second slide rails 505 on the connecting frame 410, thus forming a moving slide rail. An electric slider 506 is slidably mounted on this moving slide rail, and the moving plate 503 is connected to the multiple sets of electric sliders 506. When the electric sliders 506 are powered on, they can drive the moving plate 503 to slide on the moving slide rail. A rotatable turntable 507 is also provided on the moving plate 503, and the 3D laser scanner 21 is stably fixed on the turntable 507. A reliable rotary motor is installed at the bottom of the moving plate 503, and the shaft of the rotary motor is connected to the turntable 507. When the surveying work requires scanning the terrain at different angles, the rotating motor is started. The coil inside the motor is energized, generating a magnetic field. Under the influence of electromagnetic force, the motor rotor begins to rotate, which in turn drives the connected rotating platform 507 to rotate synchronously. As the rotating platform 507 rotates, the 3D laser scanner 21 mounted on it also changes its scanning direction, achieving multi-angle scanning of the surrounding terrain, thereby obtaining more comprehensive terrain data and providing rich and detailed information support for land spatial planning. Furthermore, two sets of photoelectric sensors 508 are installed on the first slide rail 504, clearly dividing the sliding rail into a first moving area and a second moving area. The area between the two sets of photoelectric sensors 508 is the first moving area, and the opposite side is the second moving area. The electric slider 506 is typically located within one of these moving areas. Pressure sensors 509 are provided at both ends of the first slide rail 504. When the connecting frame 410 is needed, the second slide rail 505 contacts the first slide rail 504. The pressure sensors 509 can sense the pressure change and provide feedback information for the operation of the entire moving component, ensuring its stable operation. Through the photoelectric sensor 508 and the pressure sensor 509, the electric slider 506 can be effectively prevented from leaving the moving track.

[0024] like Figure 2 , Figure 5 , Figure 6 , Figure 15As shown, a cold air box 510 and a heating box 511 are mounted on the mounting frame 501. Multiple sets of air inlet slots 512 are evenly distributed on both sides of the mounting frame 501, connecting the outside environment to the cold air box 510 and the heating box 511. When the equipment starts its relevant functions, outside air rushes in through the air inlet slots 512 under the influence of pressure difference or a fan. This air provides the necessary air source for the cooling process in the cold air box 510 and the heating process in the heating box 511, allowing outside air to smoothly enter both. A partition block 513 is installed inside the cold air box 510, dividing it into a first chamber and a second chamber. Multiple sets of ventilation holes 514 are also opened on the partition block 513, forming a funnel-like shape with one end of the larger hole facing the first chamber and the other end of the smaller hole facing the second chamber. A first fan 515 is installed in the first chamber. When the device is running, the first fan 515 starts working, drawing outside air into the first chamber through the air inlet 512. As the air passes through the vent 514, the flow rate increases and the temperature decreases due to the flow-limiting effect of the small hole, eventually entering the second chamber.

[0025] The heating chamber 511 houses a second fan 516 and a heating wire 517. The second fan 516 is positioned close to the air inlet slot 512 and between the heating wire 517 and the mounting bracket 501, a layout that improves its performance. When the ambient temperature is low, some components of the equipment, such as the lens of the 3D laser scanner 21, are prone to frost and fogging, affecting measurement work. In this situation, the second fan 516 starts operating. The airflow it generates draws outside air into the heating chamber 511 from the air inlet slot 512 and then blows it towards the heating wire 517. The heating wire 517 generates heat when energized, rapidly raising the temperature of the surrounding air. The heated air then flows along a predetermined path, mirroring the path the air entered. This warm air is delivered to the necessary equipment components, such as the air outlet ring 518, and then blown out from the air outlet 519, acting on the 3D laser scanner 21 and other equipment. This effectively removes frost and fog from the equipment lens, ensuring a clear field of view and good working condition. It avoids malfunctions or measurement errors caused by low-temperature frost and fogging, thus ensuring normal operation of the equipment and extending its service life to some extent.

[0026] An air outlet ring 518 is positioned above the movable plate 503 and fitted onto the 3D laser scanner 21. The air outlet ring 518 has multiple upward-facing air outlets 519. An air extraction pump 520 is also mounted on the mounting bracket 501. The air extraction pump 520 is connected to the cold air box 510 and the heating box 511 via a first conduit, and multiple solenoid valves are installed on the first conduit. By controlling the opening and closing of these solenoid valves, the air extraction pump 520 can selectively extract air from either the cold air box 510 or the heating box 511. The air extraction pump 520 is also connected to the air outlet ring 518 and the measuring components via a second conduit. The gas extracted from the cold air box 510 or the heating box 511 is transported to the air outlet ring 518 via the second conduit and then blown out from the air outlets 519, thereby regulating the temperature around the 3D laser scanner 21 and ensuring its normal operation in different environments.

[0027] like Figure 2 , Figure 8 , Figure 9 , Figure 13 , Figure 14 As shown, the measuring component comprises multiple sets of arc-shaped slide rails 601. Mounting brackets 602 are provided on both sides of the lifting component, providing a mounting base for other components. A connecting plate 603 is provided on the inner side of the arc-shaped slide rail 601. The connecting plate 603 and the mounting bracket 602 are rotatably connected via a movable joint, allowing the arc-shaped slide rail 601 to be adjusted within a certain angle range. A lead screw assembly is mounted on the mounting bracket 602, and a moving block 604 is configured on the lead screw assembly. A sliding groove 605 is formed at the bottom of the connecting plate 603, within which a sliding block 606 is slidably mounted. A support rod 607 is installed below the arc-shaped slide rail 601, with both ends of the support rod 607 rotatably connected to the sliding block 606 and the moving block 604 via rotating shafts. When the lead screw assembly operates, the moving block 604 moves on the lead screw, causing the arc-shaped slide rail 601 to change angle via the support rod 607, adapting to different measurement needs.

[0028] An electromagnet 608 is mounted on the top of the mounting bracket 602, while a magnetic plate is mounted on the top of the connecting plate 603. When the curved slide rail 601 needs to be fixed, the electromagnet 608 is energized and generates magnetism, attracting the magnetic plate and causing the connecting plate 603 to tightly connect with the mounting bracket 602, thereby fixing the curved slide rail 601. Multiple sets of curved slide rails 601 are symmetrically distributed to form a ring structure, which enables omnidirectional measurement of the surrounding environment. A first slide rail groove 609 is formed at the bottom of the curved slide rail 601, and second slide rail grooves 610 are formed on both the inner and outer sides of the curved slide rail 601.

[0029] The measuring assembly also includes multiple sets of electric pulleys 611 and multiple sets of optical cameras 612. The electric pulleys 611 are installed in an inverted state at the bottom of the arc-shaped slide rail 601. Their shape is arc-shaped, and the curvature is completely consistent with that of the arc-shaped slide rail 601. The wheels on the electric pulleys 611 can be engaged within the first slide rail groove 609. Limiting plates 613 are provided on both sides of the electric pulleys 611. The tops of the limiting plates 613 are engaged within the second slide rail groove 610. Multiple sets of protrusions 614 are provided on the inner side of the top of the limiting plates 613. The bottoms of these protrusions 614 are arc-shaped, allowing them to contact the arc-shaped slide rail 601. This ensures the stability of the electric pulleys 611 while reducing the contact area with the arc-shaped slide rail 601, thereby reducing friction. An optical camera 612 is located at the bottom of the curved slide rail 601 and mounted on an electric pulley 611. When the electric pulley 611 is powered on, it moves the optical camera 612 along the curved slide rail 601 to capture images of the surrounding environment and acquire image data. The curved slide rail 601 is provided with a working area and a storage area, which are staggered on the two sets of curved slide rails 601. When the measuring components are not in operation, the electric pulley 611 and the optical camera 612 can be moved to the storage area to avoid damage from external factors; when measurement work is required, they move to the working area and begin normal operation, providing rich image data for the entire topographic survey.

[0030] like Figure 2 , Figure 12As shown, a workbench 12 is mounted on the base 11, and a second electric cylinder 13 is installed on the workbench 12. A marker 14 is positioned below the workbench 12, and the shaft end of the second electric cylinder 13 passes through the workbench 12 and connects to the marker 14. When the second electric cylinder 13 is activated, it can move the marker 14 up and down. The marker 14 is cross-shaped with a blade-like bottom, a shape that facilitates insertion of the marker 14 into the soil. Between the workbench 12 and the marker 14, multiple sets of second hydraulic rods 15 are provided. One end of each second hydraulic rod 15 is connected to the workbench 12, and the other end is connected to the marker 14. The second hydraulic rods 15 provide additional support when the marker 14 is inserted into the soil, making the marker more stable. A storage tank 16 and a water pump 17 are also placed on the workbench 12. The marker 14 has multiple sets of liquid inlet chambers inside. On the inclined surface at the bottom of the marker 14, there is a liquid outlet 18, larger inside and smaller outside. The marker 14 is equipped with multiple sets of liquid inlet pipes 19, and the liquid inlet chambers communicate with the outside through the liquid inlet pipes 19 and the liquid outlet 18. The multiple sets of liquid inlet pipes 19 are connected by a first connecting pipe, and the multiple sets of liquid inlet chambers are also interconnected. The water pump 17 is connected to the first connecting pipe and the storage tank 16 through a second connecting pipe. When marking is required, the water pump 17 draws marking liquid from the storage tank 16, passes it through the second connecting pipe, the first connecting pipe, and the liquid inlet pipes 19 into the liquid inlet chamber, and finally sprays it out from the liquid outlet 18, leaving a clear mark on the ground. Simultaneously, the water pump 17 can be connected to an external water source, allowing for the spraying of a suitable amount of water on the ground before inserting the marker 14 into relatively dry soil. Once the water pump 17 is connected to the external water source, water will be transported to the inlet chamber of the marker 14 and then sprayed out from the outlet hole 18. The sprayed water can moisten and loosen the dry soil, reducing the difficulty of inserting the marker 14 into the soil and allowing it to be inserted more smoothly, ensuring the smooth progress of the marking process and facilitating subsequent measurement work.

[0031] A measurement method, employing any of the above-mentioned multidimensional measurement techniques for land spatial planning topographic surveying devices, includes the following steps: Step 1: Equipment placement and basic commissioning; First, the device is transported to the measurement location using a transport vehicle. Upon arrival, multiple sets of fixing components on the base 11 are used to firmly connect the fixing components to the ground or bearing surface, ensuring the entire device is placed stably and preventing displacement or shaking during the measurement process. After the device is properly fixed, the level detector 23 at the bottom of the support platform 32 automatically starts. The level detector 23 begins working, detecting the horizontal status of the device. If the device tilts during measurement in complex terrain, the level detector 23 will immediately detect this and report that the device is uneven. At this time, multiple sets of first electric cylinders 31 are activated. The first electric cylinders 31 are connected to the support platform 32 via connectors, and their shafts extend and retract, continuously adjusting the height of the support platform 32. The first electric cylinders 31 only stop operating when the level detector 23 indicates that the support platform 32 is horizontal.

[0032] Step 2: Install the moving components and the 3D laser scanner; The moving component is connected to the lifting component using a locking assembly. The locking base 401 and the locking block 402 cooperate through a positioning bolt 405, a spring, and a locking bolt 406. First, the positioning bolt 405 is passed through the corresponding positioning holes, allowing the locking block 402 to slide within a certain range. Then, the spring is put on, and finally, the locking bolt 406 is screwed in and tightened, so that the connecting block 502 at the bottom of the mounting bracket 501 is firmly locked in the locking slot, completing the installation of the moving component. Simultaneously, according to actual measurement needs, the operator uses a tool to turn the adjusting bolt 408, which pushes the connecting block 502, thereby adjusting the position of the mounting bracket 501. Furthermore, depending on the measurement range and accuracy requirements, it is optional to use a connecting bracket 410. When the connecting bracket 410 is required, it is installed at a preset connection position on both sides of the mounting bracket 501, located at one end of the mounting plate 409. After installation, the first slide rail 504 on the mounting plate 409 and the second slide rail 505 on the connecting frame 410 come into contact with each other, forming a movable slide rail. Then, one end of the first hydraulic rod 411 at the bottom of the connecting frame 410 is connected to the mounting frame 501 through a pin, forming a stable triangular structure.

[0033] Step 3: 3D laser scanner measurement and underground exploration; Based on the actual range of the measurement area, the operator controls the electric slider 506 to move on the movable slide rail via the controller. The movable slide rail is composed of a first slide rail 504 and a second slide rail 505. When the connecting frame 410 is not used, the photoelectric sensor 508 on the first slide rail 504 is activated and maintains a monitoring state, limiting the electric slider 506 to move only within the first moving area. When the connecting frame 410 is used, one end of the second slide rail 505 contacts the first slide rail 504, pressing the pressure sensor 509 at one end of the first slide rail 504. The pressure sensor 509 then sends a signal, causing the photoelectric sensor 508 to release the monitoring restriction on the electric slider 506. At this time, the electric slider 506 can move within the range of the first and second moving areas. According to the specific characteristics of the measured object, the 3D laser scanner 21 is activated on the controller, and various parameters, such as the scanning angle range and scanning frequency, are set. At the same time, the rotary motor is activated, driving the rotary table 507 to rotate, adjusting the angle of the 3D laser scanner 21 so that it can scan in different directions. The scanned data is transmitted to the controller in real time. In addition, the ground penetrating radar 22 is activated by the controller, and parameters such as the transmission frequency and pulse width of the ground penetrating radar 22 are set. The ground penetrating radar 22 begins to detect underground, obtain underground structural information, and transmit this information to the controller.

[0034] Step 4: Activation of the Measurement Component and Data Acquisition; Activate the lifting component, which begins to work, causing the arc-shaped slide rail 601 to unfold. As the arc-shaped slide rail 601 unfolds, a ring gradually forms between the two sets of arc-shaped slide rails 601. At this time, the electromagnet 608 on the top of the mounting bracket 602 contacts the magnetic plate on the top of the connecting plate 603, and then the electromagnet 608 is activated, using magnetic force to fix the arc-shaped slide rail 601 in place. When the arc-shaped slide rail 601 is in the folded state, the electric pulley 611 is located in the storage area to avoid collision and damage. When the arc-shaped slide rail 601 is unfolded to the working state, the electric pulley 611 moves to the working area. Activate the electric pulley 611, and the electric pulley 611 moves along the first slide rail groove 609 on the arc-shaped slide rail 601, causing the optical camera 612 mounted on it to move together, taking pictures of the surrounding environment, collecting image data, and transmitting the collected data to the controller in a timely manner.

[0035] Step 5: Environmental adjustment to ensure equipment operation; During device operation, operators constantly monitor the ambient temperature. When the ambient temperature is high, the air extraction pump 520 is activated, and the solenoid valve on the first duct is controlled to extract air from the cold air box 510. The first fan 515 inside the cold air box 510 draws in outside air. After passing through the vent 514 on the partition block 513, the air flow rate increases and the temperature decreases. The air extraction pump 520 then delivers the air through the second duct to the air outlet ring 518, and blows it out from the air outlet 519 to cool the 3D laser scanner 21 and optical camera 612. When operating in a low-temperature environment, the air extraction pump 520 is also activated, and the solenoid valve is controlled to extract air from the heating box 511. The second fan 516 inside the heating box 511 blows outside air towards the heating wire 517. After the air is heated, it is delivered to the equipment via the same path to remove water mist from the lenses of the 3D laser scanner 21 and optical camera 612, ensuring the normal operation of the equipment.

[0036] Example 2: Based on the multi-dimensional measurement topographic surveying device and method for land spatial planning provided in Example 1 of this application, Example 2 of this application proposes a multi-dimensional measurement topographic surveying device and method for land spatial planning. This Example 2 is merely a preferred embodiment of Example 1, and its implementation will not affect the individual implementation of Example 1. Example 2 of the present invention will be further described below.

[0037] like Figure 2 , Figure 10 , Figure 11As shown, the measuring assembly also includes multiple sets of electric pulleys 611 and multiple sets of optical cameras 612. The electric pulleys 611 are mounted inverted at the bottom of the curved slide rail 601. They are designed in an arc shape, with the curvature matching that of the curved slide rail 601, ensuring smooth movement of the electric pulleys 611 on the curved slide rail 601. The wheels on the electric pulleys 611 are precisely engaged within the first slide rail groove 609 at the bottom of the curved slide rail 601, preventing the electric pulleys 611 from detaching from the rail during movement. Limiting plates 613 are provided on both sides of the electric pulleys 611. The tops of the limiting plates 613 are engaged within the second slide rail grooves 610 on the inner and outer sides of the curved slide rail 601, preventing the electric pulleys 611 from wobbling left and right. On the inner top of the limiting plate 613, multiple sets of sliding wheels 615 are also provided. The sliding wheels 615 are in close contact with the arc-shaped slide rail 601, further ensuring the stability of the movement of the electric pulley 611, and also reducing the friction between the limiting plate 613 and the arc-shaped slide rail 601. The optical camera 612 is located at the bottom of the arc-shaped slide rail 601 and is mounted on the electric pulley 611. When the electric pulley 611 is powered on, it will drive the optical camera 612 to move along the arc-shaped slide rail 601 to collect images of the surrounding environment. The arc-shaped slide rail 601 is provided with a working area and a storage area, and the working area and storage area on the two sets of arc-shaped slide rails 601 are staggered. In the non-working state, the electric pulley 611 and the optical camera 612 can be moved to the storage area to avoid damage from external factors; when working, they are moved to the working area to collect data. In addition, an air intake chamber is also provided in the arc-shaped slide rail 601, and the air intake chamber is connected to the moving component through a second conduit. At the bottom of the arc-shaped slide rail 601, multiple sets of air vents 616 are provided. These air vents 616 are located within the first slide rail groove 609, allowing the air intake chamber to communicate with the outside environment through the multiple sets of air vents 616. When needed, cold air and hot air can be supplied to the air intake chamber via a moving component, thereby achieving the function of cooling or defrosting the optical camera 612. In high-temperature environments, cold air is supplied, and the cold air is blown out from the air vents 616, carrying away the heat generated by the optical camera 612 during operation and preventing it from affecting the shooting effect due to overheating. In low-temperature environments, hot air is supplied, and the hot air is blown towards the lens of the optical camera 612, quickly removing the frost condensed on the surface, ensuring that it can shoot normally and obtain clear image data.

[0038] The difference between this embodiment and embodiment one is that a sliding wheel 615 is provided on the inner side of the top of the limiting plate 613. This ensures stability during movement and effectively reduces the friction between the limiting plate 613 and the arc-shaped slide rail 601. During the movement of the electric pulley 611, the sliding wheel 615 remains in close contact with the arc-shaped slide rail 601, reducing hard friction wear between components and extending the service life of the equipment. Simultaneously, an air inlet structure is provided within the arc-shaped slide rail 601, connected to the moving component via a second conduit. This allows hot and cold air generated in the moving component to be transferred to the air inlet, and then vented to the outside through the bottom air outlet 616, enabling cooling or defrosting of the optical camera 612 under different temperature conditions. All other conditions are the same as in embodiment one, and therefore will not be repeated in this embodiment.

[0039] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
