Description

Technical Field

[0001] This disclosure generally relates to the field of elevation measurement technology, and specifically to a phased integrated elevation transfer measurement method and system for super high-rise buildings. Background Technology

[0002] With the acceleration of urbanization, super high-rise buildings have become the core carriers of urban landmark projects. Their structural designs are becoming increasingly complex, and their heights are constantly breaking records, leading to a corresponding increase in the requirements for construction surveying accuracy. Elevation control, as a core technical aspect of super high-rise building construction, directly determines the structural stability, functional realization, and overall project quality, making it a pressing technical challenge for the industry. Moreover, during construction, in addition to facing environmental factors such as wind, temperature, humidity, and sunlight, as well as elevation transfer deviations caused by the flexible swaying of the steel structure, it is also necessary to address the cumulative loads and vertical compressive deformation caused by the building's increased height. The combined effect of these problems leads to accumulated measurement errors, directly threatening building safety.

[0003] Therefore, how to provide a reliable method for elevation control measurement of super high-rise buildings has become an urgent problem to be solved. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a phased integrated elevation transfer measurement method and system for super high-rise buildings. By synergistic complementarity between steel tape measurement, total station zenith measurement and Beidou elevation measurement, the accuracy limitations of a single method can be effectively overcome, phased technology adaptation of elevation control measurement can be achieved, and the balance between measurement efficiency and accuracy throughout the entire cycle can be optimized.

[0005] In a first aspect, embodiments of this application provide a phased integrated elevation transfer measurement method for super high-rise buildings, including:

[0006] Based on the basic information of the target super high-rise building, an elevation control measurement network is established. The elevation control measurement network includes multiple basic control points of the foundation layer, elevation control points of the target layer, and measurement paths between the basic control points and the elevation control points.

[0007] Based on the phased fusion measurement system, steel tape elevation transfer measurement values, total station zenith verification values, and Beidou elevation measurement values ​​are obtained at the target layer corresponding to each phase.

[0008] The elevation transfer measurement values ​​of the steel tape, the zenith calibration values ​​of the total station, and the elevation measurement values ​​of the Beidou system are fused and analyzed to obtain the elevation control measurement fusion result, which is then used as the elevation control measurement result of the target layer.

[0009] In some embodiments, obtaining the steel tape elevation transfer measurement value of the target layer includes:

[0010] Determine the base layer i corresponding to the target layer, i≥1;

[0011] Obtain the elevation control measurement results of the basic layer i, and based on the elevation control measurement network, use a steel tape measure to measure the nominal length of the steel tape of the (i+n)th layer, where n≥1;

[0012] The nominal length of the steel ruler in the (i+n)th layer is corrected to obtain the actual length of the (i+n)th layer.

[0013] In some embodiments, the nominal length of the steel ruler of the (i+n)th layer is corrected using the following formula to obtain the actual length of the (i+n)th layer.

[0014]

[0015] in, For the (i+n)th layer of steel ruler at temperature The actual length at that time Let be the nominal length of the steel ruler on the (i+n)th floor. Correction for the steel ruler. The coefficient of thermal expansion of the steel ruler is approximately... , The temperature at which the steel ruler was used for testing. The temperature at which the steel ruler is used.

[0016] In some embodiments, obtaining the elevation control measurement results of the base layer i includes:

[0017] When the base layer i is the first layer, a second-order leveling survey is performed based on the base control points to obtain the elevation control survey results of the base layer i;

[0018] When the base layer i is not the first layer, the elevation control measurement result of the base layer i is obtained based on the elevation control measurement result of the target layer of the previous cycle segment.

[0019] In some embodiments, the total station zenith calibration value of the target layer is obtained using the following formula:

[0020] a1+d i+n -k+(a i+n -b i+n )=H i+n

[0021] Where a1 is the instrument height from the horizontal axis of the total station to the "+1000mm" elevation line of the first floor, and d i+n b represents the measurement reading of the total station at the (i+n)th floor. i+n H is the instrument height of the total station from the horizontal axis to the "+1000mm" elevation line of the (i+n)th level. i+nLet be the design elevation of the (i+n)th floor, and be a correction constant.

[0022] In some embodiments, the fusion analysis of the steel tape elevation transfer measurement value, the total station zenith check value, and the BeiDou elevation measurement value to obtain the elevation control measurement fusion result includes:

[0023] The differences between each pair of the steel tape elevation transfer measurement value, the total station zenith check value, and the Beidou elevation measurement value are obtained respectively.

[0024] If multiple of the aforementioned differences all meet the measurement error range corresponding to the engineering measurement standard, then the elevation control measurement fusion result is determined based on the arithmetic mean of the total station zenith check value and the BeiDou elevation measurement value.

[0025] Secondly, embodiments of this application provide a phased integrated elevation transfer measurement system for super high-rise buildings, including:

[0026] The basic module is used to establish an elevation control measurement network based on the basic information of the target super high-rise building. The elevation control measurement network includes multiple basic control points of the basic layer, elevation control points of the target layer, and measurement paths between the basic control points and the elevation control points.

[0027] The measurement module is used to acquire steel tape elevation transfer measurement values, total station zenith verification values, and Beidou elevation measurement values ​​at the target layer corresponding to each stage based on the phased fusion measurement system.

[0028] The fusion module is used to perform fusion analysis on the elevation transfer measurement value of the steel tape, the zenith check value of the total station, and the Beidou elevation measurement value to obtain the elevation control measurement fusion result, and use the elevation control measurement fusion result as the elevation control measurement result of the target layer.

[0029] Thirdly, embodiments of this application provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in embodiments of this application.

[0030] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in embodiments of this application.

[0031] Fifthly, embodiments of this application provide a computer program product, including a computer program, characterized in that, when the computer program is executed by a processor, it implements the method described in embodiments of this application.

[0032] This application provides a phased integrated elevation transfer measurement method and system for super high-rise buildings. Through the synergistic complementarity of steel tape measurement, total station zenith measurement, and BeiDou elevation measurement, it effectively overcomes the accuracy limitations of single methods, achieving complementary principles, contact mechanical measurement, optical ranging, satellite positioning, and error dispersion. The steel tape provides flexible and rapid intra-phase elevation transfer, the total station zenith measurement uses optical ranging accuracy to verify the cumulative error in the middle of the phase, and the BeiDou elevation measurement directly anchors the elevation of the target layer through a control reference, avoiding the accumulation of errors layer by layer. Simultaneously, multi-source data cross-validation can effectively identify and suppress the systematic bias of single methods, theoretically significantly improving the reliability and authenticity of the measurement results. Furthermore, the phased integrated measurement system proposes a phased logic of "basic transfer - same-level verification - benchmark anchoring". Within each phase, the transfer leverages the flexibility and direct measurement capabilities of steel tape to quickly establish a benchmark. Continuous phase transfer employs total station zenith distance measurement to avoid steel tape temperature correction and reversal errors, precisely controlling local accuracy. Benchmark anchoring of the core tube's key layers relies on the "one-time to top" characteristic of BeiDou elevation measurement, combined with an elevation anomaly model to eliminate layer-by-layer transfer errors. This phased technology theoretically achieves a dynamic balance between efficiency and accuracy—steel tape improves efficiency in the low-level phase, total station zenith measurement ensures accuracy in the mid-level phase, and BeiDou controls the benchmark in the high-level phase. Compared to conventional single methods, this approach is more suited to the phased characteristics of super high-rise building construction.

[0042] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] The phased fusion elevation transfer measurement method for super high-rise buildings proposed in this application can be implemented by a phased fusion elevation transfer measurement device for super high-rise buildings, which can be installed on terminal equipment or a server.

[0045] To further illustrate the technical solutions provided in the embodiments of this application, a detailed description is provided below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiments of this application provide method operation instruction steps as shown in the following embodiments or drawings, the method may include more or fewer operation instruction steps based on conventional or non-creative effort. In steps where there is no logically necessary causal relationship, the execution order of these steps is not limited to the execution order provided in the embodiments of this application. In actual processing or when the device executes the method, it may be executed sequentially or in parallel according to the method shown in the embodiments or drawings.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic flowchart of a phased integrated elevation transfer measurement method for super high-rise buildings, provided in an embodiment of this application, is shown. Figure 1 As shown, the method includes:

[0047] Step 101: Based on the basic information of the target supertall building, establish an elevation control measurement network. The elevation control measurement network includes multiple basic control points of the basic layer, elevation control points of the target layer, and measurement paths between the basic control points and the elevation control points.

[0048] It should be noted that elevation control surveying is a mapping process that accurately determines the elevation of target points by establishing a vertical control network. In the embodiments of this application, multiple control points are set up on the foundation layer and the target layer respectively, and a measurement path is established between the basic control points on the foundation layer and the elevation control points on the target layer to form an elevation control surveying network for the target super high-rise building, that is, to establish a vertical control network for the target super high-rise building.

[0049] It should also be noted that, in the embodiments of this application, the base layer is a base layer used as the basis for elevation measurement or for the transmission of elevation information, and can be selected as the first floor of the target super high-rise building or the starting floor of the stage measurement.

[0050] In one specific embodiment, based on the environmental information surrounding the target super high-rise building, such as greenery and buildings, and in accordance with the accuracy requirements of second-order precision leveling in the "National First and Second Order Leveling Measurement Specifications" (GB / T 12897), basic control points and elevation control points can be selected to establish an elevation control measurement network.

[0051] Step 102: Based on the phased fusion measurement system, obtain the steel tape elevation transfer measurement value, the total station zenith check value, and the Beidou elevation measurement value at the target layer corresponding to each phase.

[0052] It should be noted that the phased integrated measurement system divides the target super high-rise building into multiple measurement phases. Within each phase, the advantages of flexible and direct measurement using steel tape measures are utilized to quickly transfer elevation. In the mid-term verification phase, total station zenith distance measurement technology is used to ensure accuracy. This technology does not require temperature or length correction calculations for the steel tape, but it is necessary to specifically control the cumulative errors of the operation platform erected for the outer frame tube and the reverse station measurement at the cross-section of the core tube. In the benchmark anchoring phase, relying on the technical advantages of BeiDou elevation measurement of "one-time top-down, no error accumulation" and combined with accurate elevation anomaly modeling calculations, the precise anchoring of the cross-phase elevation benchmark is achieved.

[0053] Step 103: Perform a fusion analysis on the steel tape elevation transfer measurement value, the total station zenith check value, and the Beidou elevation measurement value to obtain the elevation control measurement fusion result, and use the elevation control measurement fusion result as the elevation control measurement result of the target layer.

[0054] In other words, the embodiments of this application integrate and analyze the steel tape elevation transfer measurement values, total station zenith verification values, and Beidou elevation measurement values ​​to form a closed-loop system of "basic transfer - same-level verification - benchmark anchoring". This system not only leverages the technical characteristics of each measurement method at different construction stages, but also eliminates the systematic bias of a single method through multi-source data comparison, ultimately ensuring the elevation control accuracy and construction quality of super high-rise buildings throughout their entire life cycle.

[0055] In one feasible embodiment, after obtaining the fusion results of elevation control measurements, as follows: Figure 2 As shown, the method also includes accuracy verification of the fusion results of elevation control measurements. If the fusion results of elevation control measurements meet the accuracy verification, they are directly used as the elevation control measurement results of the target layer. If the fusion results of elevation control measurements do not meet the accuracy verification, it is further determined whether there is a measurement error. If there is a measurement error, error adjustment is performed. If there is no measurement error, an adjustment plan is formulated, and adjustments are made layer by layer based on the adjustment plan to obtain the adjusted elevation control measurement fusion results. Accuracy verification is then performed again until the fusion results of elevation control measurements meet the accuracy verification.

[0056] It should be understood that, in the embodiments of this application, the limitations of accuracy of a single method are effectively overcome through the synergistic complementarity between steel tape measurement, total station zenith measurement, and BeiDou elevation measurement. Specifically, conventional elevation measurement usually relies on a single technology, such as full-process steel tape transfer, total station zenith measurement as the main method, or BeiDou elevation measurement as the independent method. Its accuracy is easily limited by inherent defects of the method. For example, steel tape is significantly affected by temperature deformation, tape length error, and human operation. Total station zenith measurement depends on a stable operating platform and has cumulative error due to station reversal. BeiDou elevation measurement is prone to reference deviation due to signal blockage in complex urban environments. However, the phased fusion measurement system proposed in the embodiments of this application achieves complementary principles through the synergistic application of three technologies: steel tape elevation transfer measurement, total station zenith measurement, and BeiDou elevation measurement. It combines contact mechanical measurement, optical ranging, satellite positioning, and error dispersion. Steel tape provides flexible and rapid intra-phase elevation transfer, total station zenith measurement uses optical ranging accuracy to verify the cumulative error in the middle of the phase, and BeiDou elevation measurement directly anchors the elevation of the target layer through control reference, avoiding the accumulation of errors through layer-by-layer transfer. Meanwhile, multivariate cross-validation can effectively identify and suppress systematic biases of a single method, theoretically significantly improving the reliability and authenticity of measurement results.

[0057] Moreover, this application innovatively proposes a phased integrated measurement system to achieve phased technical adaptation of elevation control surveying and optimize the balance between measurement efficiency and accuracy throughout the entire cycle. Specifically, conventional surveying often adopts fixed technical routes, making it difficult to consider the accuracy requirements and operational feasibility of different construction stages. For example, the low-level section requires rapid benchmark transfer but the accuracy requirements are relatively lenient; the middle-level section requires control of cumulative errors but the operating environment is complex; and the high-level section requires absolute benchmark anchoring but traditional methods result in significant cumulative errors. The phased integrated measurement system proposes a phased logic of "basic transfer - same-level verification - benchmark anchoring"; the transfer within a stage utilizes the advantages of flexible operation and direct measurement of steel tape to quickly establish benchmarks; the continuous transfer in stages uses total station zenith distance measurement to avoid steel tape temperature correction and reversal station errors, accurately controlling local accuracy; the benchmark anchoring of the core tube key layer relies on the "one-time to top" characteristic of Beidou elevation measurement, combined with the elevation anomaly model to eliminate layer-by-layer transfer errors. This phased technology theoretically achieves a dynamic balance between efficiency and accuracy—using steel rulers to improve efficiency in the low-level phase, using total station zenith measurements to ensure accuracy in the middle-level phase, and using BeiDou control benchmarks in the high-level phase. Compared to conventional single methods, this approach is more in line with the phased characteristics of super high-rise building construction.

[0058] Furthermore, the closed-loop characteristics of the phased fusion measurement system can reduce systemic biases and enhance accuracy throughout the entire lifecycle. Specifically, conventional measurement systemic biases, such as the cumulative temperature deformation of steel tape layers, the superposition of errors from total station zenith measurements, and the benchmark drift caused by urban obstruction in BeiDou elevation measurements, typically lack effective correction methods and require subsequent rework and calibration. The phased fusion measurement system proposed in this application, through multi-source data comparison and closed-loop system collaborative logic, constructs a complete closed loop of "basic transfer - peer verification - basic anchoring." The rapid transfer of steel tape provides basic data for subsequent verification; the mid-term verification of total station zenith measurements suppresses cumulative errors and provides feedback to correct biases in the transfer process; and the benchmark anchoring of BeiDou elevation measurements unifies the elevation reference at the geocentric coordinate system level, eliminating systemic biases in layer-by-layer transfer. Through multi-technology collaborative verification, the potential error space can theoretically be further compressed. This fusion model of "local precision + global reliability" not only meets the requirements of the specifications, but also eliminates the inherent systematic errors of a single method through cross-verification of multi-source data, providing a more stable and accurate theoretical guarantee for the whole-cycle elevation control measurement of super high-rise buildings.

[0059] In one feasible embodiment, such as Figure 3 As shown, the steel tape elevation transfer measurement values ​​of the target layer are obtained, including:

[0060] Step 301: Determine the base layer i corresponding to the target layer, i≥1.

[0061] It should be noted that the foundation layer i can be the foundation layer of the entire target super high-rise building, such as the first floor, or it can be the foundation layer of the current measurement cycle segment, such as the 10th, 20th, 30th, 40th, 51st, 62nd, etc. The specific selection depends on the design height and construction requirements of the target super high-rise building, and this application does not impose any specific limitations.

[0062] Step 302: Obtain the elevation control measurement results of the base layer i, and based on the elevation control measurement network, use a steel tape measure to measure the nominal length of the steel tape of the (i+n)th layer, where n≥1.

[0063] The elevation control measurement results of the base layer i can be obtained by selecting different acquisition methods depending on the type of base layer i. When base layer i is the first layer, second-order leveling is performed based on the base control points to obtain the elevation control measurement results of base layer i; when base layer i is not the first layer, the elevation control measurement results of base layer i are obtained based on the elevation control measurement results of the target layer of the previous cycle segment.

[0064] It should be understood that, for two consecutive loop segments, the target layer of the previous loop segment can serve as the base layer of the next loop segment. For example, as shown in... Figure 4 As shown, the 10th layer (L10) can be either the target layer of the first loop segment or the base layer of the second loop segment, and so on. Similarly, the 20th layer (L20) can be either the target layer of the second loop segment or the base layer of the third loop segment.

[0065] Furthermore, based on the elevation control measurement network, the nominal length of the steel tape at the (i+n)th layer is measured using a steel tape. Specifically, this involves suspending a qualified steel tape according to the pre-set elevation control points, using standard tension, and obtaining the nominal length of the steel tape between the elevation control point at the (i+n)th layer and the foundation layer i.

[0066] For example, using the southwest corner foundation control point of the core tube of the reference layer as the starting point, during the operation, the steel tape measure is first vertically suspended from the elevation control point of the (i+n)th layer along the measurement path, with a standard weight suspended at the lower end to ensure that the steel tape measure is in a plumb position and to avoid measurement deviations caused by the tilt of the steel tape measure. To reduce external environmental interference, the measurement operation should be carried out during periods of low wind to prevent the steel tape measure from swaying due to wind and affecting the accuracy of the readings. The measurement operation requires coordination between the upper and lower levels. Level instruments are set up simultaneously on the reference layer i and the (i+n)th layer, and the operators read the scale of the steel tape measure synchronously. The accuracy of the data is ensured through bidirectional reading verification.

[0067] Step 303: Correct the nominal length of the steel ruler of the (i+n)th layer to obtain the actual length of the (i+n)th layer.

[0068] It should be noted that, in the embodiments of this application, the nominal length of the steel ruler is corrected through correction calculation.

[0069] Specifically, the nominal length of the steel ruler on the (i+n)th layer is corrected using the following formula to obtain the actual length of the (i+n)th layer.

[0070]

[0071] in, For the (i+n)th layer of steel ruler at temperature The actual length at that time Let be the nominal length of the steel ruler on the (i+n)th floor. Correction for the steel ruler. The coefficient of thermal expansion of the steel ruler is approximately... , The temperature at which the steel ruler was used for testing. The temperature at which the steel ruler is used.

[0072] Therefore, by correcting the nominal length of the steel tape for the temperature, this application can effectively reduce the errors caused by the steel tape itself and the ambient temperature during the elevation transfer measurement process, and further improve the accuracy of the elevation control measurement of the target super high-rise building.

[0073] It should also be understood that, in the embodiments of this application, for each layer in the loop segment, the steel tape elevation transfer measurement value is obtained using the base layer i, which can effectively avoid measurement deviations caused by measurement operations of the steel tape elevation transfer in the loop segment, and further improve the accuracy of elevation control measurement of the target super high-rise building.

[0074] In some embodiments, in order to reduce the correction error of steel tape transfer and avoid the influence of wind on steel tape measurement during vertical elevation transfer, the staged vertical elevation transfer is checked and corrected using the total station zenith distance method, and the elevation measurement results of each cycle section are checked and measured.

[0075] Among them, the basic control point corresponding to the total station zenith measurement is set at the first-layer axis control point. The measurement path is formed by the reserved hole between the basic control point and the elevation control point to realize the upward transmission of elevation.

[0076] Specifically, the total station is set up at the basic control point and strictly leveled. The telescope is leveled (the screen displays 90°), and the reading a1 is taken from the leveling rod erected on the first floor (1st floor) at "+1m". Here, a1 is the instrument height from the horizontal axis of the total station to the first floor (1st floor) at the "+1000mm" elevation line.

[0077] Then, point the telescope towards the zenith (the screen displays 0°), place the measuring rod pad at the pre-drilled hole on the (i+n)th floor where the elevation needs to be transferred, and ensure that the crosshairs marked on the measuring rod pad intersect with the axis of that floor. The surveyor on that floor uses a level and its accessories to determine the three corner points of the measuring rod pad to make it horizontal. Then, invert the prism and place it at the center pre-drilled hole on the measuring rod pad. Operate the total station to measure the distance d. i+n .

[0078] A level instrument is placed on the (i+n)th layer, and a leveling rod is placed on the rod support. Let its reading be a. i+n Then, the leveling rod is erected near the "+1m" elevation of the (i+n)th layer, and its reading is set to b. i+n Then we have:

[0079] a1+d i+n -k+(a i+n -b i+n )=H i+n

[0080] Where a1 is the instrument height from the horizontal axis of the total station to the "+1000mm" elevation line of the first floor, and d i+n b represents the measurement reading of the total station at the (i+n)th floor. i+n H is the instrument height of the total station from the horizontal axis to the "+1000mm" elevation line of the (i+n)th level. i+n Let be the design elevation of the (i+n)th floor, and be a correction constant.

[0081] It should be understood that by moving the leveling rod up and down, its reading is made equal to the calculated b. i+n Draw a line along the bottom of the leveling rod to obtain the "+1000mm" elevation line of the i+n layer. This is the check value of the elevation line of the i+n layer determined by the zenith measurement of the total station.

[0082] Furthermore, each measurement for the total station zenith calibration should be transferred from the foundation control point of the overall foundation layer (i.e., the first floor) of the target super high-rise building, and the elevation point of the foundation layer of the next floor or the next cycle segment should not be used, thereby effectively avoiding the error of elevation transfer between cycle segments.

[0083] In a preferred embodiment, in each cycle segment, the target layer for total station zenith measurement may include at least one, such as the last layer of the cycle segment, or each layer after the middle stage of the cycle segment, such as one or more layers L5-L10 in the first cycle segment (L1-L10). Exemplarily, in this embodiment, total station zenith measurement is performed using an external climbing formwork. Therefore, due to the influence of the external climbing formwork, an operating platform needs to be erected at the outer corner of the core tube to complete the zenith elevation transfer. Furthermore, because the measurement path reserved for measurement tapers inward along the core tube wall section at the transition layer, the target layer for total station zenith measurement includes at least the transition layer and the last layer of the cycle segment.

[0084] In one optional embodiment, the BeiDou elevation measurement employs the BeiDou sixth-generation high-precision measuring instrument. This is achieved by establishing at least two reference control points as reference stations in a stable area surrounding the site, and simultaneously assuming two measuring instruments as elevation control points at the target layer, thus constructing a "dual-reference-station, dual-measuring-station" measurement system. This layout design serves a dual purpose: firstly, it enhances the stability and reliability of the measurement network through joint observations from multiple reference stations, expanding the effective observation range and optimizing the geometric structure; secondly, the mutual verification mechanism between the two measuring stations effectively improves measurement accuracy and reliability, ensuring the reliability of the observation results.

[0085] After the measuring instruments were set up, the antenna height was first measured three times independently using high-precision measuring tools, and the average value was calculated. Simultaneously, key environmental parameters such as measurement time, ambient temperature, and wind speed were recorded to provide complete environmental background information for subsequent data adjustment. Subsequently, all equipment was simultaneously put into static measurement mode and continuously observed for 40 days to obtain sufficiently stable satellite observation data. Comprehensive adjustment calculations were then performed using professional processing software. First, the geodetic height of the basic control points was calculated, and then, based on the regional elevation anomaly model, the normal height consistent with the local geoid was obtained, providing an accurate starting datum for elevation transfer.

[0086] The BeiDou elevation measurement operation is short in duration, and can be completed within 1 hour. Compared with traditional measurement methods, it can significantly reduce manpower and material costs and improve operational efficiency.

[0087] For example, such as Figure 5As shown, taking the top layer (L40) of the fourth cycle segment as the target layer as an example, specifically, elevation control points are set based on the core tube of the 40th layer. The measurement reference station is assumed to be the reference control point of the reference layer. After centering and leveling, the instrument height is measured. A Beidou instrument monitoring platform is erected on the outer scaffold of the target layer (L40). The outer facade of the platform extension wall facilitates the Beidou instrument to receive satellite signals. Using the elevation control point of the target layer as a reference, the Beidou instrument height at the elevation control point is measured using a level. Four Beidou devices at the reference control point and the elevation control point are simultaneously turned on for synchronous static measurement and continuous observation for 40 minutes to obtain sufficient and stable satellite observation data. Comprehensive adjustment calculations are performed using professional post-processing software. First, the geodetic height of the basic control point is calculated. Then, based on the regional elevation anomaly model, the normal height consistent with the local geoid is obtained, providing an accurate starting reference for elevation transfer.

[0088] In one feasible embodiment, the elevation transfer measurement using a steel tape, the total station zenith check value, and the BeiDou elevation measurement value are fused and analyzed to obtain the elevation control measurement fusion result. This includes: obtaining the pairwise differences between the steel tape elevation transfer measurement value, the total station zenith check value, and the BeiDou elevation measurement value; if multiple differences all meet the measurement error range corresponding to the engineering measurement standard, then the elevation control measurement fusion result is determined based on the arithmetic mean of the total station zenith check value and the BeiDou elevation measurement value.

[0089] In other words, for each target layer, especially when the target layer is the top layer of a cyclic segment, the steel tape elevation transfer measurement value, the total station zenith calibration value, and the BeiDou elevation measurement value of the target layer are obtained separately. Then, the differences between these values ​​are obtained, such as the first difference between the steel tape elevation transfer measurement value and the total station zenith calibration value, the second difference between the total station zenith calibration value and the BeiDou elevation measurement value, and the third difference between the steel tape elevation transfer measurement value and the BeiDou elevation measurement value. It is then determined whether the first, second, and third differences all meet the measurement error range corresponding to the engineering measurement standard. If so, it is determined that all three measurement results meet the elevation control requirements for super high-rise buildings. To meet the requirements of elevation control measurement, the arithmetic mean of the total station zenith calibration value and the BeiDou elevation measurement value is used to determine the elevation control measurement fusion result. That is, the arithmetic mean of the total station zenith calibration value and the BeiDou elevation measurement value is used as the elevation control measurement fusion result of the target layer. If not, it is further determined whether there is a measurement error. If there is a measurement error, error adjustment is performed. If there is no measurement error, an adjustment plan is formulated, and adjustments are made layer by layer based on the adjustment plan. The steel tape elevation transfer measurement value, the total station zenith calibration value, and the BeiDou elevation measurement value are obtained again, as well as the differences between each pair of the steel tape elevation transfer measurement value, the total station zenith calibration value, and the BeiDou elevation measurement value.

[0090] Exemplarily, multiple target floors of a certain target super high-rise building were measured to obtain the elevation measurement result table of the core tube elevation control points in Table 1.

[0091] Table 1

[0092]

[0093] Judging from the data, the difference between the Beidou elevation measurement and the zenith measurement of the total station is relatively small, indicating that the measurement results of these two methods are closer to the true value. In contrast, the result of the steel tape elevation transfer measurement is slightly inferior. However, according to the regulations on elevation transfer in the engineering survey standard GB50026-2020, for the height range of 150m < H ≤ 200m, the allowable deviation of measurement is 30mm. The differences of the above three measurement methods do not exceed the deviation range allowed by this specification, so they can all meet the requirements of the elevation measurement of super high-rise buildings.

[0094] Furthermore, it can be seen from the data in the table that there are certain differences between any two of the three conventional measurement methods:

[0095] The steel tape elevation transfer measurement value and the Beidou elevation measurement: The difference at the 40th floor is 0.011m (11mm), at the 51st floor is 0.016m (16mm), and at the 62nd floor is 0.02m (20mm). The maximum difference reaches 20mm.

[0096] The zenith calibration value of the total station and the steel tape elevation transfer measurement value: The difference at the 40th floor is 0.007m (7mm), at the 51st floor is 0.011m (11mm), and at the 62nd floor is 0.014m (14mm). The maximum difference is 14mm.

[0097] The zenith calibration value of the total station and the Beidou elevation measurement: The difference at the 40th floor is 0.004m (4mm), at the 51st floor is 0.005m (5mm), and at the 62nd floor is 0.006m (6mm). The maximum difference is 6mm.

[0098] If only a single method is used for conventional measurement, as the measurement height increases and the measurement process progresses, errors may accumulate, and different methods have their own systematic errors. For example, the steel tape elevation transfer measurement is affected by factors such as temperature and tape length, and there is an accumulated error for the total station zenith calibration during station change. If the maximum difference of 20mm is used to roughly measure the possible error range of conventional single measurement methods.

[0099] It can be seen that the staged fusion measurement system proposed in the embodiment of the present application compares and fuses multi-source data. Taking the 62nd floor as an example, the difference between the Beidou elevation measurement and the total station zenith calibration is relatively small (6mm). It is determined that these two results are closer to the true value, and their arithmetic mean (282.288m) is taken as the most probable value.

[0100] From the perspective of maximum error control: the maximum possible error of a conventional single measurement method is 20mm, while the fusion measurement, by selecting reliable values, controls the error within a smaller range of 6-11mm (considering the difference data from each floor, the minimum difference is 4mm, and the maximum is 20mm, but after selecting reliable values ​​through multi-source data fusion, the actual error range is significantly reduced). Taking the maximum possible error of 20mm as a reference, the accuracy improvement is approximately 50%-70%, leaning towards around 60%. This means that the fusion measurement method can more accurately determine the elevation values ​​of elevation control points, reducing the impact of measurement errors on the construction of super high-rise buildings.

[0101] From the perspective of data stability and reliability: conventional measurement methods exhibit relatively dispersed differences between data layers, and errors may accumulate due to systematic errors from a single method. In contrast, fusion measurement, through comparison of multi-source data, such as steel tape elevation transfer measurement, total station zenith calibration, and BeiDou elevation measurement, cross-verifies the measurement results, making them more stable and reliable. For example, by selecting the average of the BeiDou elevation measurement and total station zenith calibration results as the most probable value, the influence of errors from a single method is reduced, further improving measurement accuracy.

[0102] Overall, this fusion measurement method improves the accuracy of results by about 50%-70% (more likely around 60%) compared to conventional measurement methods, providing more accurate and reliable data for the elevation measurement of super high-rise buildings and effectively reducing the impact of measurement errors on construction.

[0120] In some embodiments, the measurement module 12 is specifically used for:

[0121] The total station zenith check value for the target layer is obtained using the following formula:

[0122] a1+d i+n -k+(a i+n -b i+n )=H i+n

[0123] Where a1 is the instrument height from the horizontal axis of the total station to the "+1000mm" elevation line of the first floor, and d i+n b represents the measurement reading of the total station at the (i+n)th floor. i+n H is the instrument height of the total station from the horizontal axis to the "+1000mm" elevation line of the (i+n)th level. i+n Let be the design elevation of the (i+n)th floor, and be a correction constant.

[0124] In some embodiments, the fusion module 13 is specifically used for:
