Description

Technical Field

[0001] This invention relates to the field of ground engineering, and more particularly to a ground leveling device and method based on regional flatness assessment. Background Technology

[0002] Floor flatness is an important indicator in floor pouring, reflecting the surface flatness of the floor in the ground project. If the floor surface is uneven, it will affect the placement of furniture or equipment and drainage function. Therefore, in the construction stage, accurately assessing the surface flatness of the floor and leveling it before hardening is an indispensable step in the ground project.

[0003] Currently, existing technologies typically use measuring rulers and levels to assess the flatness of the concrete surface after it has been laid. However, these technologies rely on manual operation, and if the operators lack sufficient experience, the accuracy of the flatness assessment will be low. Existing technologies use point cloud scanning equipment to assess the flatness of the concrete surface after it has been laid. However, these technologies are cumbersome to operate and require complex point cloud data processing. These existing technologies have limitations in practical use, resulting in poor reliability of the flatness assessment. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a floor leveling device and method based on regional flatness assessment. This method enables rapid assessment of regional flatness during concrete paving, thereby identifying uneven areas and leveling the floor, thus improving the reliability of floor leveling.

[0005] To achieve the above objectives, embodiments of the present invention provide a ground leveling device based on regional flatness assessment, comprising: a base, a pole, a scanning rotation control module, a laser ranging module, a terminal processing control module, and a leveling module; the base is mechanically connected to the pole, the pole is mechanically connected to the scanning rotation control module, the scanning rotation control module is mechanically connected to the laser ranging module, and both the scanning rotation control module and the laser ranging module are electrically connected to the terminal processing control module; the terminal processing control module is electrically connected to the leveling module; the scanning rotation control module is used to control the horizontal rotation of the laser ranging module in the plane of the base. The system obtains the horizontal rotation angle; controls the laser ranging module to rotate vertically in the plane of the base to obtain the vertical rotation angle; the laser ranging module scans the test points on the ground based on the horizontal and vertical rotation angles to obtain ranging data; the terminal processing control module receives the horizontal rotation angle, vertical rotation angle, and ranging data; based on the horizontal and vertical rotation angles and ranging data, it obtains a fitted trend line; based on the fitted trend line, it obtains the regional flatness assessment result; and sends the regional flatness assessment result to the flattening module so that the flattening module can flatten the ground according to the regional flatness assessment result.

[0006] This invention proposes a floor leveling device based on regional flatness assessment. It collects horizontal rotation angles, vertical rotation angles, and distance measurement data through a scanning rotation control module and a laser ranging module. A terminal processing control module processes this data to obtain a fitted trend line. The flatness of the area is then assessed based on this trend line, yielding a regional flatness assessment result. This result is sent to the leveling module for floor leveling. The device uses horizontal and vertical rotation angles to help fit a straight line within the area's plane. By determining the elevation of the test points along this line, it can identify any uneven areas and facilitate floor leveling. Furthermore, the rotating laser ranging module can assess the flatness of more areas, enabling rapid regional floor flatness assessment. This assessment can be completed during concrete paving, mitigating the limitations of traditional floor leveling. Data processing requires only horizontal and vertical rotation angles and distance measurement data, simplifying calculation parameters and improving the reliability of floor leveling.

[0007] Furthermore, the terminal processing control module receives horizontal rotation angle, vertical rotation angle, and distance measurement data; based on the horizontal rotation angle, vertical rotation angle, and distance measurement data, it obtains a fitted trend line; based on the fitted trend line, it obtains the regional flatness assessment result; and it sends the regional flatness assessment result to the flattening module, so that the flattening module can flatten the ground according to the regional flatness assessment result. This module includes: a data receiving unit, a distance value acquisition unit, an elevation value acquisition unit, a trend line fitting unit, a flatness assessment unit, and a flattening control unit. The data receiving unit receives horizontal rotation angle, vertical rotation angle, and distance measurement data. The system includes: rotation angle, vertical rotation angle, and distance measurement data; a distance value acquisition unit to obtain the measured distance value based on the vertical rotation angle and distance measurement data; an elevation value acquisition unit to obtain the measured elevation value based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and base pole elevation; a trend line fitting unit to obtain a fitted trend line based on the measured distance value and measured elevation value; a flatness evaluation unit to obtain the area flatness evaluation result based on the preset trend line and the fitted trend line; and a flatness control unit to control the flatness module to flatten the ground based on the area flatness evaluation result.

[0008] Through the above scheme, the terminal processing control module collects horizontal rotation angle, vertical rotation angle, and distance measurement data through the data receiving unit. The distance value acquisition unit calculates the measured distance value based on the vertical rotation angle and distance measurement data, which can determine the distance between the ground test point and the ground leveling device. The elevation value acquisition unit calculates the measured elevation value based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole, which can determine the elevation of the corresponding ground test point. The trend line fitting unit obtains a fitted trend line based on the measured distance value and measured elevation value. The flatness evaluation unit sets a preset trend line and then fits the trend line. The flatness of the area is evaluated along the trend line to obtain the flatness evaluation result. Finally, the flatness control unit controls the flatness module to flatten the ground according to the flatness evaluation result. Thus, by obtaining the distance and elevation of the ground test points, a fitted trend line is obtained, and the flatness of the area is evaluated on the ground test points along the fitted trend line. This enables rapid evaluation of the flatness of the area ground. The flatness evaluation of the area ground can be completed during the concrete paving process, which weakens the limitations of ground leveling. Data processing only requires horizontal rotation angle, vertical rotation angle and distance measurement data, simplifying the calculation parameters and thus improving the reliability of ground flatness.

[0009] Furthermore, the distance value acquisition unit is used to obtain the measured distance value based on the vertical rotation angle and the distance measurement data, including: acquiring the vertical rotation angle based on a preset angle interval; obtaining the distance measurement data based on the vertical rotation angle; and calculating the measured distance value based on a preset geometric relationship using the vertical rotation angle and the distance measurement data.

[0010] The above scheme obtains the vertical rotation angle according to the preset angle interval, measures the distance data of the test point of the floor according to the vertical rotation angle, and calculates the measured distance value according to the preset geometric relationship, the vertical rotation angle and the distance data. By simplifying the data processing process, a simple geometric relationship is used to characterize the distance relationship between the test point of the floor and the floor leveling device, providing a reliable data basis for subsequent acquisition of fitting trend lines and regional flatness assessment, thereby improving the reliability of floor leveling.

[0011] Furthermore, the elevation value acquisition unit is used to obtain the measured elevation value based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole, including: obtaining the initial elevation value based on the preset geometric relationship, horizontal rotation angle, vertical rotation angle, and distance measurement data; and obtaining the measured elevation value by subtracting the initial elevation value from the elevation of the base pole.

[0012] The above solution, based on preset geometric relationships, vertical rotation angles, and distance measurement data, combined with horizontal rotation angles, can determine the initial elevation value of the ground test point. Then, by subtracting the elevation from the elevation of the base pole, the measured elevation value is obtained, eliminating the influence of possible errors in the ground leveling device itself, and obtaining the elevation of the ground test point. By simplifying the data processing process, the elevation of the ground test point is obtained, providing a reliable data basis for subsequent acquisition of fitting trend lines and regional flatness assessment, thereby improving the reliability of ground leveling.

[0013] Furthermore, the trend line fitting unit is used to obtain a fitted trend line based on the measured distance value and the measured elevation value, including: obtaining the slope coefficient and elevation coefficient of the fitted trend line based on the measured distance value, the measured elevation value and the preset fitting algorithm; and obtaining the fitted trend line based on the slope coefficient and elevation coefficient of the fitted trend line.

[0014] The above scheme obtains the slope coefficient and elevation coefficient of the fitted trend line by measuring distance and elevation values ​​and using a preset fitting algorithm. The fitted trend line is then processed to obtain the fitted trend line. Thus, the process of assessing the flatness of the ground is set on the fitted trend line. There is no need to conduct the flatness assessment after the concrete paving is completed. Instead, the flatness of the ground can be assessed in real time during the concrete paving process, which improves the efficiency of identifying uneven areas. Furthermore, only the data on the fitted trend line needs to be analyzed, reducing the amount of data processing and thus improving the reliability of the flatness of the ground.

[0015] Furthermore, the flatness assessment unit is used to obtain regional flatness assessment results based on preset trend lines and fitted trend lines, including: obtaining preset fitted trend line slope coefficient and preset fitted trend line elevation coefficient based on preset trend lines; if the difference between the preset fitted trend line slope coefficient and the fitted trend line slope coefficient meets the flatness slope requirement, obtaining regional flatness slope assessment results; if the difference between the preset fitted trend line elevation coefficient and the fitted trend line elevation coefficient meets the flatness elevation requirement, obtaining regional flatness elevation assessment results; and obtaining regional flatness assessment results based on regional flatness slope assessment results and regional flatness elevation assessment results.

[0016] The above scheme sets a preset trend line. By analyzing the slope coefficient of the preset fitted trend line and the slope coefficient of the fitted trend line, as well as the elevation coefficient of the preset fitted trend line and the elevation coefficient of the fitted trend line, the slope and elevation of the test points on the fitted trend line can be quickly analyzed and evaluated to obtain the regional flatness evaluation results. The flatness of the ground can be quickly evaluated in real time during the concrete paving process, simplifying the calculation parameters and improving the reliability of the ground flatness.

[0017] Furthermore, the leveling control unit is used to control the leveling module to level the ground based on the regional leveling assessment results, including: calculating the elevation difference between adjacent ground test points based on the regional leveling assessment results and the fitted trend line; calculating the average elevation deviation and standard elevation deviation based on several sets of elevation differences between adjacent ground test points; and controlling the leveling module to level the ground based on the average elevation deviation and standard elevation deviation.

[0018] By using the above scheme, the elevation difference between adjacent floor test points is calculated, and the average elevation deviation and standard deviation of the floor test points on the fitted trend line are calculated. Thus, by analyzing the local elevation difference between adjacent floor test points, the floor can be locally leveled. This allows for real-time rapid assessment and leveling of the floor flatness during the concrete paving process, improving the reliability of floor flatness.

[0019] Furthermore, the base includes: a base with several bolts; several bolts for leveling the base.

[0020] The above solution, by setting leveling bolts, reduces the problem of large errors in measurement data caused by uneven ground. By ensuring the accuracy of data measurement, the accuracy of ground flatness assessment is guaranteed, thereby improving the reliability of ground flatness.

[0021] This invention also provides a method for leveling a floor based on regional flatness assessment, comprising: receiving horizontal rotation angle, vertical rotation angle, and distance measurement data; obtaining a fitting trend line based on the horizontal rotation angle, vertical rotation angle, and distance measurement data; obtaining a regional flatness assessment result based on the fitting trend line; and sending the regional flatness assessment result to a leveling module so that the leveling module levels the floor according to the regional flatness assessment result.

[0022] This invention proposes a method for leveling a floor based on regional flatness assessment. It collects horizontal rotation angles, vertical rotation angles, and distance measurement data, processes this data to obtain a fitted trend line, and then assesses the regional flatness based on this trend line. The assessment result is then sent to a leveling module for floor leveling. The method uses horizontal and vertical rotation angles to help fit a straight line within the plane of the area. By determining the elevation of the test points on this line, it can identify any uneven areas and facilitate floor leveling. Furthermore, a rotating laser distance measurement module can be used to assess the flatness of more areas, thus enabling rapid assessment of regional floor flatness. This assessment can be completed during concrete paving, mitigating the limitations of floor leveling. Data processing only requires horizontal and vertical rotation angles and distance measurement data, simplifying calculation parameters and improving the reliability of floor leveling.

[0023] Furthermore, based on the horizontal rotation angle, vertical rotation angle, and distance measurement data, a fitted trend line is obtained, including: obtaining the measured distance value based on the vertical rotation angle and distance measurement data; obtaining the measured elevation value based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and base pole elevation; and obtaining the fitted trend line based on the measured distance value and measured elevation value.

[0024] The above scheme collects horizontal rotation angle, vertical rotation angle, and distance measurement data. The measured distance value is calculated using the vertical rotation angle and distance measurement data to determine the distance between the test point and the floor leveling device. The measured elevation value is calculated based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole to determine the elevation of the corresponding test point. A fitted trend line is obtained based on the measured distance and elevation values. By setting a preset trend line, the flatness of the area is evaluated along the fitted trend line to obtain the area flatness evaluation result. Finally, the leveling module is controlled to level the floor based on the area flatness evaluation result. Thus, by acquiring the distance and elevation of the test points, a fitted trend line is obtained, and the area flatness of the test points along the fitted trend line is evaluated, enabling rapid evaluation of the area floor flatness. The area floor flatness evaluation can be completed during concrete paving, reducing the limitations of floor leveling. Data processing only requires horizontal rotation angle, vertical rotation angle, and distance measurement data, simplifying calculation parameters and improving the reliability of floor flatness.

[0038] One possible implementation method has the following structure for each module: See [link / description] Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic diagram of the mechanical structure of a floor leveling device based on regional flatness assessment, provided in one embodiment of the present invention. Figure 1 ; Figure 4 A schematic diagram of the mechanical structure of a floor leveling device based on regional flatness assessment, provided in one embodiment of the present invention. Figure 3 ; Figure 5 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 1 ;like Figure 2 , Figure 3 and Figure 4As shown, the external structure of the ground leveling device for regional flatness assessment consists of a base 1, a pole 2, a scanning rotation control module 3, and a laser ranging module 4. The base 1 is mechanically connected to the pole 2, the pole 2 is mechanically connected to the scanning rotation control module 3, and the scanning rotation control module 3 is mechanically connected to the laser ranging module 4. The scanning rotation control module 3 rotates horizontally and vertically in the plane of the base 1. The laser ranging module 4 rotates vertically in the plane of the base 1 along with the scanning rotation control module 3 and scans the ground test points. The terminal processing control module 5 is located inside the ground leveling device for regional flatness assessment. Both the scanning rotation control module 3 and the laser ranging module 4 are electrically connected to the terminal processing control module 5 to realize data acquisition signal transmission and module control signal transmission.

The scanning rotation control module 3 and the laser ranging module 4 can be connected to the terminal processing control module 5 by wired electrical connection or wireless connection, etc.

[0039] The working principle of each module is as follows: Base 1 and pole 2 support scanning rotation control module 3, laser ranging module 4, and terminal processing control module 5. Scanning rotation control module 3 rotates horizontally in the plane of base 1 to obtain a horizontal rotation angle, and also rotates vertically in the plane of base 1 to obtain a vertical rotation angle. These horizontal and vertical rotation angles are then transmitted to terminal processing control module 5 for processing. Laser ranging module 4 rotates vertically in the plane of base 1 along with scanning rotation control module 3 and scans the ground test points to obtain ranging data, which is then transmitted to terminal processing control module 5 for processing.

In addition to receiving the horizontal and vertical rotation angles from the scanning rotation control module 3 for area flatness assessment, it can also directly set the horizontal and vertical rotation angles according to user needs and send them to the terminal processing control module 5 for processing into control commands. This commands control the scanning rotation control module 3 to rotate, driving the laser ranging module 4 to collect ranging data, thereby achieving the area flatness assessment.

[0040] This invention proposes a ground leveling device based on regional flatness assessment. It collects horizontal rotation angle, vertical rotation angle, and distance measurement data through a scanning rotation control module and a laser ranging module. A terminal processing control module processes this data to obtain a fitted trend line. The regional flatness is then assessed based on this trend line, yielding a regional flatness assessment result. This result is sent to the leveling module, which then levels the ground according to the assessment. The device utilizes the horizontal rotation angle... By using a vertical rotation angle to assist in fitting a straight line within the plane of the area, it is only necessary to determine the elevation of the test points on that line to reflect whether there are uneven areas on the ground, thus enabling ground leveling. Furthermore, the rotation laser ranging module can be used to evaluate the flatness of more areas, thereby achieving rapid assessment of regional ground flatness. Regional ground flatness assessment can be completed during the concrete paving process, reducing the limitations of ground leveling. Data processing only requires horizontal rotation angle, vertical rotation angle, and ranging data, simplifying calculation parameters and improving the reliability of ground flatness.

[0041] As an example of an embodiment of the present invention, the terminal processing control module 5 is used to receive horizontal rotation angle, vertical rotation angle, and distance measurement data; obtain a fitting trend line based on the horizontal rotation angle, vertical rotation angle, and distance measurement data; obtain a regional flatness assessment result based on the fitting trend line; and send the regional flatness assessment result to the flatness module so that the flatness module can flatten the ground according to the regional flatness assessment result.

[0042] One possible implementation method is described in [link to implementation details]. Figure 5 and Figure 6 , Figure 5 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 1 ; Figure 6 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 2 ;like Figure 5 and Figure 6 As shown, the terminal processing control module 5 receives the horizontal rotation angle. Vertical rotation angle θ i and ranging data d i Then, based on the vertical rotation angle θ i and ranging data d i Calculate the measured distance value L i According to the horizontal rotation angle Vertical rotation angle θ i Distance measurement data d i Calculate the measured elevation value based on the base and upright elevation h0, and then calculate the measured distance L. i The system calculates and fits a trend line based on the measured elevation value.

The area flatness assessment result is then sent to the flattening module 6. The flattening module 6 receives the area flatness assessment result and adjusts the flattening equipment parameters according to the content of the area flatness assessment result to achieve flattening of the uneven area.

[0043] Through the above scheme, the terminal processing control module collects horizontal rotation angle, vertical rotation angle, and distance measurement data through the data receiving unit. The distance value acquisition unit calculates the measured distance value based on the vertical rotation angle and distance measurement data, which can determine the distance between the ground test point and the ground leveling device. The elevation value acquisition unit calculates the measured elevation value based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole, which can determine the elevation of the corresponding ground test point. The trend line fitting unit obtains a fitted trend line based on the measured distance value and measured elevation value. The flatness evaluation unit sets a preset trend line and then fits the trend line. The flatness of the area is evaluated along the trend line to obtain the flatness evaluation result. Finally, the flatness control unit controls the flatness module to flatten the ground according to the flatness evaluation result. Thus, by obtaining the distance and elevation of the ground test points, a fitted trend line is obtained, and the flatness of the area is evaluated on the ground test points along the fitted trend line. This enables rapid evaluation of the flatness of the area ground. The flatness evaluation of the area ground can be completed during the concrete paving process, which weakens the limitations of ground leveling. Data processing only requires horizontal rotation angle, vertical rotation angle and distance measurement data, simplifying the calculation parameters and thus improving the reliability of ground flatness.

Figure 1 ; Figure 6 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 2 ;like Figure 5 and Figure 6 As shown, based on an initial rotation angle of θ s and the final rotation angle is θ e The vertical rotation angle θ is obtained according to the preset angle interval Δθ. i According to the vertical rotation angle θ i Determine the location of the floor test point and obtain the distance from the floor test point to the floor leveling device for regional flatness assessment, i.e., the distance measurement data d. i Based on the preset geometric relationship, by vertically rotating by an angle θ i and ranging data d i Calculate the measured distance value L i The specific calculation formula is as follows:

[0046] L i =d i .sin(θ i );

[0047] The above scheme obtains the vertical rotation angle according to the preset angle interval, measures the distance data of the test point of the floor according to the vertical rotation angle, and calculates the measured distance value according to the preset geometric relationship, the vertical rotation angle and the distance data. By simplifying the data processing process, a simple geometric relationship is used to characterize the distance relationship between the test point of the floor and the floor leveling device, providing a reliable data basis for subsequent acquisition of fitting trend lines and regional flatness assessment, thereby improving the reliability of floor leveling.

[0048] As an example of an embodiment of the present invention, the elevation value acquisition unit 53 is used to obtain a measured elevation value based on the horizontal rotation angle, the vertical rotation angle, the distance measurement data and the elevation of the base pole, including: obtaining an initial elevation value based on a preset geometric relationship, the horizontal rotation angle, the vertical rotation angle and the distance measurement data; and obtaining the measured elevation value by subtracting the initial elevation value from the elevation of the base pole.

Figure 1 ; Figure 6A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 2 ;like Figure 5 and Figure 6 As shown, based on preset geometric relationships and horizontal rotation angles... Vertical rotation angle θ i and ranging data d i Calculate the initial elevation value h c The formula for calculating the initial elevation value is as follows:

[0050]

[0051] By comparing the elevation h0 of the base pole with the initial elevation value h c By subtracting the values, we obtain the measured elevation value p. i The specific calculation formula is as follows:

[0052]

[0053] The above solution, based on preset geometric relationships, vertical rotation angles, and distance measurement data, combined with horizontal rotation angles, can determine the initial elevation value of the ground test point. Then, by subtracting the elevation from the elevation of the base pole, the measured elevation value is obtained, eliminating the influence of possible errors in the ground leveling device itself, and obtaining the elevation of the ground test point. By simplifying the data processing process, the elevation of the ground test point is obtained, providing a reliable data basis for subsequent acquisition of fitting trend lines and regional flatness assessment, thereby improving the reliability of ground leveling.

[0054] As an example of an embodiment of the present invention, the trend line fitting unit 54 is used to obtain a fitted trend line based on the measured distance value and the measured elevation value, including: obtaining the slope coefficient and the elevation coefficient of the fitted trend line based on the measured distance value, the measured elevation value and the preset fitting algorithm; and obtaining the fitted trend line based on the slope coefficient and the elevation coefficient of the fitted trend line.

[0055] One possible implementation method is to construct an objective function based on a preset fitting algorithm, such as the least squares method, as follows:

[0056]

[0057] Combined with the measured distance value L i and measured elevation value p i The slope coefficient 'a' and elevation coefficient 'b' of the fitted trend line are calculated using the following formulas:

[0058]

[0059] Based on the slope coefficient 'a' and elevation coefficient 'b' of the fitted trend line, a fitted trend line is constructed as follows:

[0060] p = aL + b;

[0061] The above scheme obtains the slope coefficient and elevation coefficient of the fitted trend line by measuring distance and elevation values ​​and using a preset fitting algorithm. The fitted trend line is then processed to obtain the fitted trend line. Thus, the process of assessing the flatness of the ground is set on the fitted trend line. There is no need to conduct the flatness assessment after the concrete paving is completed. Instead, the flatness of the ground can be assessed in real time during the concrete paving process, which improves the efficiency of identifying uneven areas. Furthermore, only the data on the fitted trend line needs to be analyzed, reducing the amount of data processing and thus improving the reliability of the flatness of the ground.

[0062] As an example of an embodiment of the present invention, the flatness assessment unit 55 is used to obtain a regional flatness assessment result based on a preset trend line and a fitted trend line, including: obtaining a preset fitted trend line slope coefficient and a preset fitted trend line elevation coefficient based on the preset trend line; if the difference between the preset fitted trend line slope coefficient and the fitted trend line slope coefficient meets the flatness slope requirement, obtaining a regional flatness slope assessment result; if the difference between the preset fitted trend line elevation coefficient and the fitted trend line elevation coefficient meets the flatness elevation requirement, obtaining a regional flatness elevation assessment result; and obtaining a regional flatness assessment result based on the regional flatness slope assessment result and the regional flatness elevation assessment result.

[0063] One possible implementation involves pre-setting a trend line and obtaining the slope coefficient 'a' of the pre-set fitted trend line. s And the preset fitting trend line elevation coefficient b s The preset trendline expression is as follows:

[0064] p = a s L+b s ;

[0065] Based on the difference between the slope coefficient of the preset fitted trend line and the slope coefficient of the fitted trend line, the regional flatness slope assessment result is obtained. Based on the difference between the elevation coefficient of the preset fitted trend line and the elevation coefficient of the fitted trend line, the regional flatness elevation assessment result is obtained. Finally, based on the regional flatness slope assessment result and the regional flatness elevation assessment result, the regional flatness assessment result is obtained. Specifically, in one test of this embodiment, the rotation angle of the scanning rotation control module 3 in the horizontal direction of the plane where the base 1 is located is set to 30°. The height of the laser ranging module 4 from the reference surface of the base plate (equivalent to the elevation h0 of the base pole) is 60cm. The preset angle interval Δθ is 1°. Scanning measurements are performed on 10 ground test points. The collected data is shown in Table 1, as follows:

[0066] Table 1 Experimental Data

[0067]

[0068] Based on the data in Table 1, the expression for the fitted trend line is calculated as: p = 0.01L + 0.3; in this embodiment, the preset fitted trend line is: p = 0 × L + 0.2; it can be seen that the difference between the preset fitted trend line slope coefficient and the fitted trend line slope coefficient is 0.01cm, and the difference between the preset fitted trend line elevation coefficient and the fitted trend line elevation coefficient is 0.1cm. This indicates that the ground test point on the fitted trend line is slightly higher than the plane where the preset fitted trend line is located by 0.1cm, and there is a small additional slope with a slope value of 0.01cm. In this embodiment, the flatness slope requirement is set as a ≤ 0.012, b ≤ 0.15. Therefore, it can be seen that the ground test point on the fitted trend line is slightly higher than the plane where the preset fitted trend line is located by 0.1cm, and there is a small additional slope with a slope value of 0.01cm, which meets the flatness slope requirement. The result of the regional flatness assessment is that no flattening operation is required.

[0069] The above scheme sets a preset trend line. By analyzing the slope coefficient of the preset fitted trend line and the slope coefficient of the fitted trend line, as well as the elevation coefficient of the preset fitted trend line and the elevation coefficient of the fitted trend line, the slope and elevation of the test points on the fitted trend line can be quickly analyzed and evaluated to obtain the regional flatness evaluation results. The flatness of the ground can be quickly evaluated in real time during the concrete paving process, simplifying the calculation parameters and improving the reliability of the ground flatness.

[0070] As an example of an embodiment of the present invention, the leveling control unit 56 is used to control the leveling module to level the ground based on the regional leveling assessment results, including: calculating the elevation difference between adjacent ground test points based on the regional leveling assessment results and the fitted trend line; calculating the average elevation deviation and the standard elevation deviation based on several sets of elevation differences between adjacent ground test points; and controlling the leveling module to level the ground based on the average elevation deviation and the standard elevation deviation.

[0071] In one specific implementation method, if the regional flatness assessment result meets the flatness and slope requirements, it indicates that the overall flatness meets the requirements. To make the flatness assessment more accurate, this embodiment also performs local analysis to check for excessive elevation differences. Based on the regional flatness assessment results and the fitted trend line, the adjacent ground test points (p) are calculated. i and p i+1 Elevation difference Δp i,i+1 The specific calculation formula is as follows:

[0072] △p i,i+1 =|p i+1 -pi |;

[0073] Using the 10 data points in Table 1, the elevation difference Δp between adjacent ground test points is... i,i+1 The results are shown in Table 2:

[0074] Table 2. Results of elevation difference between adjacent ground test points.

[0075]

[0076]

[0077] As shown in Table 2, the local elevation differences at data points 1, 2, 3, and 4 are relatively large. Therefore, this area needs to be locally leveled. The reliability of the leveling can be further verified by calculating the average elevation deviation and standard deviation of the elevation using the elevation differences between adjacent test points. The specific formulas are as follows:

[0078]

[0079] In this embodiment, the elevation difference Δp between the 10 data points in Table 1 and their adjacent ground test points is used. i,i+1 The calculated average elevation deviation is 0.2cm and the standard deviation is 0.4cm. This is significantly different from the preset average elevation deviation threshold of 0.1cm and standard deviation threshold of 0.06cm. This indicates that the surface where the fitted trend line is located has large local undulations and needs further leveling. The result is sent to the leveling module 6 to control the leveling module 6 to level the ground.

[0080] By using the above scheme, the elevation difference between adjacent floor test points is calculated, and the average elevation deviation and standard deviation of the floor test points on the fitted trend line are calculated. Thus, by analyzing the local elevation difference between adjacent floor test points, the floor can be locally leveled. This allows for real-time rapid assessment and leveling of the floor flatness during the concrete paving process, improving the reliability of floor flatness.

[0081] As an example of an embodiment of the present invention, the base 1 includes: the base 1 is provided with a plurality of bolts 7; the plurality of bolts 7 are used to level the base 1.

[0082] One possible implementation method is described in [link to implementation details]. Figure 7 , Figure 7 A schematic diagram of the mechanical structure of a floor leveling device based on regional flatness assessment, provided in one embodiment of the present invention. Figure 4 ;like Figure 7 As shown, the base 1 is equipped with 4 bolts 7 to level the ground leveling device based on the regional flatness assessment before the regional flatness assessment begins. In this embodiment, in addition to using bolts to achieve leveling, a sliding element that can adjust the elevation can also be used.

[0083] The above solution, by setting leveling bolts, reduces the problem of large errors in measurement data caused by uneven ground. By ensuring the accuracy of data measurement, the accuracy of ground flatness assessment is guaranteed, thereby improving the reliability of ground flatness.

[0084] Example 2

[0085] See Figure 6 , Figure 6 This is a schematic flowchart illustrating the steps of a ground leveling method based on regional flatness assessment, provided in one embodiment of the present invention. Figure 6 As shown in the figure, this embodiment of the invention proposes a ground leveling method based on regional flatness assessment, including steps 101 to 104, each step of which is as follows:

[0086] Step 101: Receive horizontal rotation angle, vertical rotation angle, and distance measurement data;

[0087] Step 102: Based on the horizontal rotation angle, vertical rotation angle, and distance measurement data, obtain the fitted trend line;

[0088] Step 103: Based on the fitted trend line, obtain the regional flatness assessment results;

[0089] Step 104: Send the regional flatness assessment results to the flatness module so that the flatness module can flatten the ground according to the regional flatness assessment results.

[0090] In one specific implementation method, after receiving the horizontal rotation angle, vertical rotation angle and distance measurement data, the terminal processing control module 5 calculates the fitting trend line, obtains the area flatness assessment result based on the fitting trend line, and then sends the area flatness assessment result to the leveling module 6. The leveling module 6 receives the area flatness assessment result and adjusts the leveling equipment parameters according to the content of the area flatness assessment result to achieve leveling of the uneven area.

[0091] This invention proposes a method for leveling a floor based on regional flatness assessment. It collects horizontal rotation angles, vertical rotation angles, and distance measurement data, processes this data to obtain a fitted trend line, and then assesses the regional flatness based on this trend line. The assessment result is then sent to a leveling module for floor leveling. The method uses horizontal and vertical rotation angles to help fit a straight line within the plane of the area. By determining the elevation of the test points on this line, it can identify any uneven areas and facilitate floor leveling. Furthermore, a rotating laser distance measurement module can be used to assess the flatness of more areas, thus enabling rapid assessment of regional floor flatness. This assessment can be completed during concrete paving, mitigating the limitations of floor leveling. Data processing only requires horizontal and vertical rotation angles and distance measurement data, simplifying calculation parameters and improving the reliability of floor leveling.

[0092] As an example of an embodiment of the present invention, step 102 includes steps 201 to 203, each of which is as follows:

[0093] Step 201: Based on the vertical rotation angle and distance measurement data, obtain the measured distance value;

[0094] Step 202: Based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole, obtain the measured elevation value;

[0095] Step 203: Based on the measured distance and elevation values, obtain the fitted trend line.

[0096] One possible implementation method is described in [link to implementation details]. Figure 5 and Figure 6 , Figure 5 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 1 ; Figure 6 A geometrical diagram of a floor leveling device based on regional flatness assessment, provided for one embodiment of the present invention. Figure 2 ;like Figure 5 and Figure 6 As shown, the terminal processing control module 5 receives the horizontal rotation angle. Vertical rotation angle θ i and ranging data d i Then, based on the vertical rotation angle θ i and ranging data d i Calculate the measured distance value L i According to the horizontal rotation angle Vertical rotation angle θ i Distance measurement data d iCalculate the measured elevation value based on the base and upright elevation h0, and then calculate the measured distance L. i The system calculates and fits a trend line based on the measured elevation value. It then compares and evaluates the area flatness assessment result based on the preset trend line and the fitted trend line. The area flatness assessment result is then sent to the flattening module 6. The flattening module 6 receives the area flatness assessment result and adjusts the flattening equipment parameters according to the content of the area flatness assessment result to achieve flattening of the uneven area.

[0097] The above scheme collects horizontal rotation angle, vertical rotation angle, and distance measurement data. The measured distance value is calculated using the vertical rotation angle and distance measurement data to determine the distance between the test point and the floor leveling device. The measured elevation value is calculated based on the horizontal rotation angle, vertical rotation angle, distance measurement data, and the elevation of the base pole to determine the elevation of the corresponding test point. A fitted trend line is obtained based on the measured distance and elevation values. By setting a preset trend line, the flatness of the area is evaluated along the fitted trend line to obtain the area flatness evaluation result. Finally, the leveling module is controlled to level the floor based on the area flatness evaluation result. Thus, by acquiring the distance and elevation of the test points, a fitted trend line is obtained, and the area flatness of the test points along the fitted trend line is evaluated, enabling rapid evaluation of the area floor flatness. The area floor flatness evaluation can be completed during concrete paving, reducing the limitations of floor leveling. Data processing only requires horizontal rotation angle, vertical rotation angle, and distance measurement data, simplifying calculation parameters and improving the reliability of floor flatness.
